BALTIMORE and IRVING, Texas—Sinclair and Nexstar Media Group are launching a consumer awareness campaign Sept. 17 to educate viewers in 13 markets about the benefits of NextGen TV.

The campaign will run in seven Nexstar markets—including Cleveland; Austin, Texas; Kansas City, Mo.; Tampa, Fla.; Portland, Ore.; Buffalo, N.Y.; and Denver—and in six Sinclair markets—Las Vegas; Columbus, Ohio; Nashville, Tenn.; Baltimore; Seattle; and Washington.

The campaign’s goal is to raise viewer awareness of NextGen TV. Available as a TV spot and a social media post, the promo asks: “On game days, who’s got next? With NextGen TV, you do.” The message informs viewers that NextGen TV delivers their favorite games in UHD and immersive sound, as well as their local news, weather and favorite shows.

The campaign builds on the consumer-education initiative Sinclair developed and tested in Columbus during the summer.

“Consumer education is an important part of accelerating adoption of NextGen TV,” said Del Parks, president of technology at Sinclair. “Our experience in Columbus demonstrated that when consumers understand what NextGen TV is, how to access it and the benefits it can deliver, we can meaningfully increase engagement. By partnering with Nexstar, we can take what we learned from that campaign and bring a consistent, consumer-friendly message to viewers across an even broader group of markets. Now is the time for all broadcasters to begin promoting the advantages of NextGen TV.”

The campaign also includes website GoNextGenTV.com, where consumers can learn what NextGen TV programming is available in their area using a search-by-ZIP code feature.

The site also explains the steps needed to set up a NextGen TV viewing experience, whether with an ATSC 3.0-compatible set or a converter box and existing TV. It offers an extensive list of consumer devices—including converter boxes, NextGen TV sets, antennas and cables—as well as a frequently asked questions section and a list of the standard’s benefits.

“The transition to NextGen TV has been a story of broadcasters working together to bring new capabilities to TV viewers. The cooperation and collaboration with Sinclair to educate those viewers is the next chapter in that story,” said Brett Jenkins, Nexstar’s executive vice president and chief technology and digital officer. “We’re confident that as consumers come to understand the advantages of NextGen TV, they will be eager to adopt it and will seek out TV models with ATSC 3.0 capability.”

KINGS PARK, NY—Multidyne Video & Fiber Optic Systems will introduce SilverBack-IP, the newest member of its SilverBack Series of fiber camera adapters, at the 2026 IBC Show, Sept. 11-14 at the RAI Amsterdam. SilverBack-IP brings native SMPTE ST 2110 connectivity to Multidyne’s fiber camera platform, providing a direct path for integrating digital cinema cameras into modern IP production environments, the company said.

Multidyne developed the SilverBack Series to help content producers bring the cinematic quality of digital cinema cameras into live multi-camera production. The lightweight, vendor-agnostic adapters convert digital cinema cameras for SMPTE studio-camera workflows and have been deployed across live sports, concerts, television productions, houses of worship and other professional production environments.

Purpose-built for the industry’s transition from SDI, SilverBack-IP retains the series’s mobility, camera flexibility and familiar operational benefits while moving the transport layer to IP. The new design enables production teams to connect their preferred cinema cameras directly to SMPTE ST 2110 networks while maintaining the camera-centric workflows that have made SilverBack a fixture in live cinematic production.

SilverBack-IP features dual 25GbE network interfaces and supports SMPTE ST 2022-7 hitless protection across the two fibers within SMPTE hybrid cable, providing redundant network paths for demanding live production environments. Two 12G-SDI and two 3G-SDI connections accommodate a broad range of HD and UHD workflows, with video, audio, intercom and data encapsulated and de-encapsulated as standardized IP streams.

The IP architecture removes many of the point-to-point limitations associated with traditional camera chains. Rather than requiring signals such as intercom, timing and video to be discretely connected and distributed through dedicated hardware, SilverBack-IP makes those signals available within the ST 2110 network infrastructure. Integrated intercom, for example, can operate as an ST 2110-30 audio essence flow, allowing production teams to source and associate intercom audio through the network instead of a dedicated point-to-point connection.

The dual 12G-SDI capability also positions SilverBack-IP for emerging immersive production requirements. Stereoscopic cameras that generate discrete right- and left-eye UHD signals can deliver two simultaneous 12G-SDI feeds into the adapter, allowing both signals to be transported into the ST 2110 environment. The architecture extends SilverBack’s vendor-agnostic philosophy to new generations of digital cinema and immersive cameras, allowing producers to select the most suitable cameras.

SilverBack-IP’s studio camera-style physical design puts controls, menu access and system status directly in front of the camera operator. Full-size professional connectors complement the operator-centric interface, marking a departure from the traditional ENG-style cameraback configuration of earlier SilverBack systems. The result is a familiar studio-camera experience while retaining the flexibility of adapting a digital cinema camera for live production.

SilverBack-IP supports both 12V and 24V camera systems when paired with appropriate Multidyne power extension solutions, accommodating traditional cinema cameras as well as newer high-power camera platforms, the company said. The adapter can operate independently of a camera as a standalone fiber gateway, allowing production teams to place the unit remotely and transport video, intercom and other signals between SDI endpoints and IP networks.

Multidyne will be in Stand 11.C12.

As U.S. TV station owners’ prospects increasingly depend on how they deal with challenges posed by the global 5G juggernaut, newfound flexibility in the use of the fast-evolving cellular technology is opening more promising paths to their success in the battles ahead.

“We’re now at our last chance to remain a viable communications platform across all devices,” said Mark Aitken, president of ONE Media Technologies, Sinclair’s engineering unit. The opportunity lies in the fact that multiple strands in the long and complex evolution toward broadcast and mobile service integration are coming together on commercially viable chipsets capable of making things work across all fronts, he added.

“Whether our integration into the 5G domain is by way of ATSC 3.0, 5G Broadcast or some combination of the two, we as an organization don’t care,” Aitken said. What matters above all is “over-the-air broadcast remaining viable.”

Whatever Means Necessary
Many in broadcast TV circles, including Aitken, first viewed 5G Broadcast as an approach to multicasting video and other content to smartphones aimed at circumventing ATSC 3.0. But Aitken said he saw things differently after learning about the ATSC 3.0/5G Broadcast strategy implemented by Castanet, with live LPTV prototype services supporting the current 3GPP (Third Generation Partnership Project) version of 5G Broadcast on ATSC 3.0 transmitters in Las Vegas and Silicon Valley.

In fact, Aitken said, ONE Media plans to test the Castanet platform on Sinclair’s WIAV-CD Washington, D.C., once the LPTV station receives the multiplexing and exciter equipment from Castanet partner Televes.

“We can see how [the Castanet solution] plays against the widest variety of 3.0 receivers,” Aitken said. “I think we have a bigger variety than just about anybody. If it comes out as claimed, why wouldn’t we support another means?”

How long before the solutions developed by Sinclair and Castanet will be relevant to getting ATSC 3.0/5G convergence off the ground remains to be seen. Eventually—and not so far in the future—TV station owners will be able to bolster the long-term viability Aitken said they’re looking for by leveraging 5G as a so-called bootstrapped radio access network (RAN) component of ATSC 3.0 transmitters through implementation of the recently announced Broadcast-to-Everything (B2X) standard.

The emerging 5G/TV convergence stems from the fact that both ATSC and the wireless industry’s 3GPP have moved their respective architectures ever closer through successive waves of standards development. Like LTE, ATSC 3.0 employs orthogonal frequency-division multiplexing (OFDM) modulation, and like the New Radio (NR) version of 5G, the B2X Radio Access Network (BRAN) framework will employ OFD Multiple Access (OFDMA) to support slicing capabilities with disaggregation between core and edge processing sites.

Optimizing 5G
But B2X does away with reliance on 5G broadband, although it employs techniques similar to those adopted in 3GPP’s latest Release 19 version. The idea with B2X is to optimize execution of all 5G-like functionalities in accordance with ATSC 3.0 architecture while ensuring smooth interoperability between the two domains.

Current U.S. broadcaster options related to using 5G Broadcast with ATSC 3.0, as supported by the Sinclair and Castanet solutions, are a bridge to opportunities across a virtually unlimited range of 5G multicast verticals anchored by B2X, ATSC President Madeleine Noland said. As for broadcasters that feel constrained by the fact that bandwidth availability for 5G multicasting is highly restricted by the current “lighthouse” sharing scenario of ATSC 3.0 spectrum, where Federal Communications Commission rules require full-power stations to continue ATSC 1.0 broadcasts, Noland said to stay tuned.

“I think it’s a good idea to keep an eye on B2X and what that can enable in the future,” she said.

One example of bridge-building to BTX already underway is in India, where government-run broadcaster Prasar Bharati and its technology partners are conducting direct-to-mobile (D2M) 5G/ATSC 3.0 service trials in 19 cities in preparation for commercial rollout by year-end. Smartphones and other devices will run on chipsets developed by Saankhya Labs, now owned by Tata Group’s Tejas Networks, with investment support from Sinclair. This full-reception system is built on a patented, software-defined radio platform that supports demodulator, antenna, filter and other front-end components, Aitken noted.

As this phase of the D2M strategy takes hold across India, Prasar Bharati and its tech partners have begun gearing up for the transition to B2X with high-profile standards development support from the Indian Institute of Technology (IIT) Bombay. Sinclair and the other partners backing Saankhya Labs have launched Sampige Semiconductors to create B2X chipsets “in roughly the same time frame that semiconductors supporting 5G Broadcast will be appearing in some smartphones,” Aitken said.

Ready for Qualcomm
LPTV spectrum owners, who are free of 1.0/3.0 simulcast requirements, represent an immediate market for 5G Broadcast solutions providers, as long as they implement 5G Broadcast over ATSC 3.0 transmitters as required by the FCC. Castanet is allied with what founder and Executive Chairman Vern Fotheringham describes as a coalition of LPTV spectrum holders with footprints covering 60% of the U.S. population. Castanet documents point to expectations of expanding that base to 95%.

Castanet’s immediate goal is to ensure broadcast customers are fully prepared to capitalize on the projected 2028 rollout of smartphones equipped with new Qualcomm chipsets, Fotheringham said. Those chipsets support 3GPP Release 19 advancements that bring TV reception and 5G applications together on smartphones and tablets without requiring a separate tuner or SIM card and with no impact on a user’s data cap. These
systems-on-chips (SOCs) will enable interleaving, which allows non-TV 5G signaling to share the same spectrum with TV broadcasts, and CAS muting, which prevents that TV protection mechanism from impeding the 5G flows.

Once the smartphone turnover cycle puts these new devices into mass circulation sometime around 2031-32, the floodgates should open for broadcasters, Fotheringham said. “Our capex for the 5G Broadcast master site is equivalent to the cost of a 4G macro-level site but serves population areas covered by hundreds or even thousands of those cell sites,” he added. This translates to a massive cost reduction for 5G multicasting compared to MNO reliance on narrowcast streaming, he said.

The LPTV Factor
Of course, there are two sides to 5G tech advances, with benefits also accruing in directions unfavorable to the ATSC 3.0 agenda. One such trend is the widely publicized push by some segments of the LPTV community for freedom from FCC rules limiting use of 5G Broadcast to ATSC 3.0 broadcasters.

Last month, LPTV broadcaster XGN and sister company X1 Mobile, along with Tyche Media LLC, owner of WCRN-LD Boston, filed a petition with the FCC requesting permission to completely replace ATSC TV broadcasts with 5G Broadcast distribution. This goes beyond last year’s filing by the largest LPTV station owner HC2 Broadcasting—soon to be acquired by Dish founder Charlie Ergen—that seeks authority to use 5G Broadcast overlaid on a single ATSC 1.0 TV channel with no 3.0 requirement.

The proposed rule change would require LPTV stations to stream at least one free TV channel and to devote at least 50% of the remaining spectrum capacity to the types of public-safety applications ATSC 3.0 broadcasters are considering with use of 5G, such as emergency alerts, first-responder data and GPS backup.

WCRN for the past three years has been running FCC-sanctioned tests demonstrating 5G Broadcast delivery of linear programming streams, emergency alerts, global positioning and many other public-safety solutions, said Frank Copsidas, founder of XGN/X1 and founder and president of the LPTV Broadcast Association. Elsewhere, Copsidas said, LPTV stations in France, Africa and other countries with fewer regulatory restrictions are pursuing commercial rollouts of 5G Broadcast services.

“By 2029, short-form programming produced by the TDF Group for LPTV distribution will be available to 90% of the French population,” he said.

Another player pushing 5G Broadcast—but with the full expression of the Release 19 version—is Austria-based Big Blue Marble.
With support for interleaving and CAS muting, the company’s Nakolos platform is ideally suited for enabling 5G Broadcast over existing DVB-T2 infrastructure in Europe free of licensing restrictions, said Johann Mika, Big Blue Marble’s chief innovation officer.

“From a regulatory perspective, in Austria, for example, we can ask for a 10-year license for 5G Broadcast with no issue,” Mika said. But, as with Castanet, the “missing piece for us is mobile phones.” Broadcast organizations across Europe are “working to get phone costs lower,” he added, noting that with the wait for Release 19-capable chipsets, things “aren’t 100% set yet.”

But when they are, those Qualcomm-designed chipsets will also open the gate for MNOs and 5G fixed wireless access (FWA) providers to put 5G Broadcast to use over their own networks, said Andrew Towe, a 5G Broadcast specialist and participant in media streaming standards who worked closely with WCRN at the outset of the 5G Broadcast testing project in Boston.

“It will be pretty impressive when you get to an ecosystem with all the 5G advanced capabilities working on smartphones,” Towe said, noting there is a widespread expectation in many quarters, including among European broadcasters, that when that happens, “5G is going to take over.”

Aitken is well aware of the “threat,” which he said is a big reason suppliers and broadcasters must be incentivized to move ahead with preparations for 5G rollout on ATSC 3.0, free of the 1.0 broadcast burden.

“We’re just waiting for somebody to cut the shackles,” he said. “Until they do, we have to hop around on one foot with our hands behind our backs.”

BOTHELL, Wash.—The Alliance for IP Media Solutions (AIMS) has announced that ITDev and Bolin Technology have joined the organization as its newest members.

The additions bring a professional PTZ camera and AV-over-IP hardware manufacturer and a FPGA design and IP licensing specialist into the alliance, further broadening the range of expertise represented among AIMS members as adoption of IPMX and SMPTE ST 2110-based standards continues to expand across broadcast and Pro AV, the group said.

“Both Bolin Technology and ITDev each bring a different, valuable perspective to AIMS,” said Andrew Starks, director of product marketing, Macnica Broadcast & Pro AV; Board Member and Marketing Work Group Chair, AIMS. “ITDev’s FPGA design expertise supports the engineering work behind IPMX, while Bolin’s experience building PTZ cameras for broadcast and live production gives us a direct line into how these standards perform in the field.

BOCA RATON, Fla.—Florida Atlantic University said Dolby Laboratories has acquired a video-compression technology portfolio FAU had developed through a long-standing research partnership with OP Solutions LLC (OPS).

At the heart of the portfolio is technology that contributed to Versatile Video Coding (VVC), also known as H.266, the international video-compression standard finalized in 2020 by the International Organization for Standardization and the International Telecommunication Union. VVC reduces video data requirements by approximately 50% compared with the previous High Efficiency Video Coding standard while maintaining the same visual quality.

Although VVC is not yet widely deployed by streaming services, due to the lack of hardware support, the codec has been adopted by Brazil's TV 3.0 standard as well as DVB broadcasters in Europe. ATSC approved the standard for 3.0 in April.

The portfolio comprises 683 intellectual property assets, including 250 granted patents worldwide and 73 United States patents, which were invented by FAU researchers in the College of Engineering and Computer Science. The research was sponsored by OPS, which provided strategic research support, patent development and commercialization expertise, while FAU faculty conducted the underlying technical research.

“This acquisition exemplifies the power of combining world-class faculty expertise with strong industry partnerships,” said FAU President Adam Hasner. “Technology developed at Florida Atlantic has evolved from groundbreaking university research into an international standard and is now part of the portfolio of one of the world’s leading media technology companies. Its applications span digital media, national security, autonomous systems and emerging AI technologies, demonstrating how FAU research is driving innovation and economic impact on a global scale.”

The transaction also highlights the success of the research and commercialization partnership between FAU and OPS. Through the collaboration, OPS sponsored advanced video-coding research at FAU while helping guide intellectual property development and commercialization efforts.

“This achievement illustrates the power of sustained investment in research excellence and strategic partnerships,” said Stella Batalama, Ph.D., dean of the College of Engineering and Computer Science. “Working with OP Solutions, our faculty took video-compression research from the lab into a global standard, and that work is now part of Dolby’s portfolio. It is a clear example of FAU research reaching real products and returning value to the university.”

Sixteen U.S. patents developed through the FAU-OPS collaboration have been declared essential to the VVC standard and are licensed through the Access Advance VVC patent pool for worldwide commercial implementation. Dolby acquired the portfolio from OPS, which held the patent rights following assignment from FAU.

The International Telecommunication Union (ITU), the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) are seeking innovations that significantly surpass the capabilities of the current Versatile Video Coding (VVC) standard and have issued a call for proposals for the next generation of video compression technology.

The formal registration for proposals period runs from Aug. 1 to Sept. 1.

The call for proposals from the Joint Video Experts Team—a partnership of ITU-T Study Group 21 (multimedia, content delivery and cable TV) and ISO/IEC JTC 1/SC 29 (coding of audio, picture, multimedia and hypermedia information)—marks the start of the process to develop a new video coding standard by 2029.

Submissions will be evaluated by the 45th meeting of the Joint Video Experts Team next January.

The project continues a longstanding tradition of joint work that has produced VVC (ITU H.266 | ISO/IEC 23090-3), along with the Emmy Award-winning High Efficiency Video Coding (ITU H.265 | ISO/IEC 23008-2) and Advanced Video Coding (ITU H.264 | ISO/IEC 14496-10).

The call for proposals covers a broad range of content types and use cases, including streaming services, video conferencing, social media, gaming, content creation, extended reality (XR), machine vision, and high-dynamic-range (HDR) video.

The Joint Video Experts Team said proposals may introduce entirely new coding tools, improved system architectures or novel approaches to advance the state of the art in video compression.

Reflecting an increasingly diverse video ecosystem, innovations will be evaluated across diverse test content ranging from HDR and ultra-high-definition (UHD) video to gaming, screen content and user-generated media.

The call invites innovations that demonstrate either significantly improved compression performance or important new functionality beyond the capabilities of VVC.

The groups said they welcome innovations addressing future multimedia requirements, including those arising from the continued evolution of AI-enabled content creation, processing, analysis and delivery.

All proposals will undergo rigorous evaluation through both formal subjective quality assessment and objective performance measurements.

Proposals can be submitted here.

Imagine building a TV business based on streaming IP-packetized local TV channels to viewers on a market-by-market basis. Who would have thought of that?

Well, it turns out the broadcasters, broadcast vendors and CE companies responsible for developing the ATSC 3.0 standard aren’t the only ones. In early July, a tech company called “FreeCast,” specializing in providing “streaming Platform-as-a-Service” solutions, threw its hat into the ring with the announcement of FreeCast Cities.

The service combines local TV channels, free streaming channels, premium television services, on-demand entertainment and subscription management into a single consumer experience. Currently in beta, FreeCast will enable consumers to access this content via supported TVs, mobile devices, computers and connected streaming platforms, according to a press release.

The FreeCast Cities announcement came about three months after a company called Landover Saturn 5 proposed to the Federal Communications Commission that it conduct an auction of a nationwide block of TV channels 28–36.

The two are unrelated in most respects but share a common thread: They both give the FCC even more to consider as it works on its final report and order regarding ATSC 3.0, which is expected to be out before the end of the year.

To be sure, neither proposal is a slam dunk. FreeCast must successfully navigate its way through rights negotiations with stations and their networks before it has a chance of fulfilling what it calls its “consumer-focused design philosophy,” namely, “One City. One Login. All Your Television.”

Regarding the Landover proposal, the FCC has much to consider, not the least of which is whether it wishes to empower a private entity to conduct the proposed auction on its behalf.

What’s worrisome is these proposals further muddy the waters for the commission as it considers its NextGen TV report and order—something a television industry seeking clarity on sunsetting today’s DTV standard and an expeditious transition can ill afford.

A Bit Overwhelming
A month or so ago, I reported about my stroke and my upcoming open-heart surgery to bypass four significantly clogged cardiac arteries.

Since then, I have undergone the surgery and am convalescing at home. While I am not ready to run down the aisles at NAB Show any time soon, the doctors assure me that after my outpatient rehab is complete, I will be back in the swing of things. In fact, following the operation, my surgeon told me I now have “the heart of a 20-year-old.”

I also wanted to report that the outpouring of support, well wishes and prayers from both family and friends, as well as many in the TV industry, has been a bit overwhelming. I want to thank everyone for their supportive texts, emails, phone calls, cards and flowers. They have meant the world to me.

As I sign off, I will echo the closing of my last column. I am eager to put this all behind me and get back in the swing of things, reporting on our fast-changing industry.

Interest in the Broadcast Positioning System, or BPS—a relatively new offshoot of the ATSC 3.0 standard—continues to grow, sparking the creation of a new company tasked with developing the technology for commercial deployments.

In addition to their regular services, broadcasters that have adopted ATSC 3.0 can also deploy BPS by transmitting very precise timing signals. The BPS signals are received and decoded similarly to satellite-delivered global positioning system (GPS) signals (also referred to as “Global Navigation Satellite System” or GNSS signals), and may be used to pinpoint the receiver’s geographic location and as a highly accurate time reference.

Too Many Eggs in One Basket
An obvious question about the development and rollout of such an alternative to the long-established GPS technology is: Why is it needed? Doesn’t GPS function well enough in most applications?

The answer lies in the dependency upon GPS signals that now exists among many business sectors and industrial operations. These extend far beyond vehicular navigation.

GPS has become an invisible utility that provides precision time to U.S. critical infrastructure, so much so that the National Security Council describes it as a single point of failure, with the National Institute of Standards and Technology (NIST) estimating the risk to the U.S. economy exceeding $1 billion per day, according to Sam Matheny, formerly executive vice president of the National Association of Broadcasters’ Broadcast Positioning System group and now CEO of Merkhet Solutions, an independent company launched by NAB in June.

“Critical infrastructure includes the energy grid, communications networks, financial and data centers—the infrastructure that undergirds every facet of modern life,” Matheny said.

Harvey Arnold, senior vice president of engineering at Sinclair, which has been working with the NAB to develop BPS, said GPS delivery of timing information is very much a “single thread” with no place to go should that thread break.

“As time goes on, you hear more and more about GPS’s lack of resiliency,” Arnold said. “GPS transfers time, not just positional information. This time-transfer function is very important.”

As GPS relies on reception of relatively weak signals from orbiting satellites, he noted, it is especially vulnerable to blocking or jamming—intentional or otherwise—from stronger terrestrial RF sources.

“People don’t pay much attention to how easy it is to jam or ‘spoof’ GPS signals,” Arnold said. “However, this can affect such things as financial transactions, which require accurate time stamps. It’s after jamming or spoofing attacks that people get excited.

“GPS has become the ‘gold standard’ for time transfer,” he continued. “It’s ubiquitous, but it’s a weak signal that’s subject to jamming and spoofing. Even space junk has the potential to disrupt it. Such issues are common to any space-based communications system. Russia and China have a backup for their GPS systems; we don’t.”

Bad Things Do Happen
Matheny noted that GPS disruptions aren’t just speculative—they can and do occur.

“On March 19, 2026, 12 airplanes reported false positions at Dallas-Fort Worth airport as a result of GPS interference,” Matheny said. “In mid-May 2024, solar storms impacted GPS such that farmers across the Midwest were advised to postpone use of their GPS-assisted tractors during planting season.”

Matheny also flagged a January 2022 incident in which GPS service was disrupted for more than 33 hours in the Denver area, affecting both aircraft and ground-based users over eight square miles. The cause of the outage was later determined to be accidental, traced to a transmitter inadvertently operating in GPS spectrum.

GPS jamming or spoofing (the replacement of valid GPS information with spurious signals) occurs frequently in military combat zones and also along the U.S. southern border, Matheny noted.

“While illegal, there are numerous low-power jammers that can be found for sale online,” he said. “These are known to be used by people who would like to conceal their movements, but in doing so also create interference issues in their vicinity.”

A commercial-grade GPS jammer is currently available for military applications, Matheny added, and Russia has demonstrated its ability to use satellite-transmitted signals to interfere with GPS operations.

BPS to the Rescue
Given these vulnerabilities, BPS technology seems to have arrived just in time to bolster the existing GPS navigational and time-transfer applications.

“The beauty of BPS is that it can easily become part of a broadcast system,” Arnold said. “Transmitters and towers are already in place. Once stations have converted to ATSC 3.0, the cost to add BPS is nominal.

Added Matheny: “The amount of equipment is relatively small in that you need a BPS synchronizer and a source of reference time. However, I’ll note that BPS has to function as a single, synchronized, managed network and is not something that a station would just go out and do on their own as each station has to be part of a coordinated system. That is why we launched Merkhet Solutions to deploy BPS nationwide service.”

Where Are We Now?
The concept of using broadcaster-originated signals as a GPS-adjunct dates back about five years, in a paper delivered at the 2021 NAB Broadcast Engineering and IT (BEIT) conference by its inventors: NAB’s Tariq Mondal, Bob Weller and Sam Matheny. Demonstrations and field testing began shortly afterwards and continue to the present.

Matheny said Merkhet Solutions currently has a cooperative R&D agreement in place with NIST covering several aspects of the technology, as well as a contract
with the U.S. Department of Transportation for BPS field studies. He also described testing of BPS technology in a power grid application.

“We partnered with Dominion Energy [a Richmond, Va.-based energy producer and distributor] for this effort, and have BPS installed at one of the largest power substations on the East Coast,” he said. “BPS is being evaluated for use with phasor measurement units and fault detection systems. The results thus far are positive and meet the needs of energy grid operations.”

Dominion Energy testing involves over-the-air signals from WHUT-TV Washington, D.C., and WNUV Baltimore, Arnold said.

“WNUV receives WHUT-TV, which is about 40 miles away,” he explained. “It’s configured as the ‘leader’ station which is referenced to the coordinated universal [CUT or UTC]time reference sent from the NIST facility in Boulder, Colo.”

The Baltimore station (WNUV) receives the time information signal from the Washington station (WHUT-TV), resynchronizes to it, and then retransmits this precision time information in a “leader-follower” manner, Arnold continued.

“As the BPS network develops, such ‘leader-followers’ can serve as important tools in helping to economically extend the coverage of the BPS network,” he added.

Sinclair is getting ready to turn on another BPS station (WIAV-CD, a Class-A station in Washington, D.C.) to determine how many hops are possible before the timing signal is degraded.

“This will also provide a third location for testing and analysis of BPS positioning information,” Arnold said.

Time to Retire ATSC 1.0
BPS is a unique application of ATSC 3.0 and cannot be added to ATSC 1.0, according to Metheny.

“It has to do with the signal and framing structure where BPS is leveraging the bootstrap emission time, which doesn’t exist in 1.0,” he said. “Additionally, the use of a highly robust physical layer pipe [PLP] in ATSC 3.0 enables a BPS signal that operates below the noise floor, which also isn’t possible with 1.0.”

Arnold and Matheny agreed that a nationwide BPS deployment won’t be possible until a hard date for ATSC 1.0 shutoff is established.

“We need more transmitters and geographic separation for good positional information in implementing BPS,” Arnold said. “This requires the sunsetting of ATSC 1.0. That’s one of our pushes right now.”

Matheny added: “A firm time frame for transition would certainly be helpful. That is true for BPS as well as for consumers and NextGen TV generally. Having a timeline certainty enables everyone to plan and invest accordingly. My hope is that BPS can help accelerate the transition, as it solves a well-defined and big problem.”

NEW YORK—The IAB Tech Lab has released AAMP 2.3, a notable update to the Agentic Advertising Management Protocols that are designed to help organizations deploy AI agents within existing advertising infrastructure.

More specifically, AAMP 2.3 expands the open framework for Agentic Advertising with enterprise-ready deployment, integrated privacy diligence, stronger pricing integrity, broader platform support, and the finalization of key industry standards.

“The industry has already shown what's possible with AI agents,“ IAB Tech Lab CEO Anthony Katsur said. “Now, the focus is making them reliable in the environments where advertising actually happens,. Organizations need infrastructure they can trust. They need AI agents that work across systems, respect consumer privacy regulations, and make decisions with repeatable accuracy. AAMP 2.3 gives the industry that foundation, moving agentic advertising into everyday business.…

The release comes as agentic advertising is making rapid progress, with AI agents demonstrating how they can automate planning, buying, selling and optimization.

AAMP 2.3 is designed to accelerate the next phase of that development by providing the industry with a common framework that enables those capabilities to operate within the technology environments companies already use. It lets organizations deploy model-agnostic agentic stacks that connect to major inventory sources while remaining interoperable across the broader advertising ecosystem.

The release also introduces new capabilities making production deployments more practical. Organizations can deploy AAMP through Amazon Bedrock AgentCore; expand buying across additional platforms, including Metal integrate Google Ad Manager reporting; and build on new open-source contributions from HyperMindz and Mixpeek. Together, these enhancements give buyers, sellers, publishers and technology providers greater flexibility to integrate AI agents into existing workflows using the systems they already have in place, the IAB Tech Lab said.

As AI agents begin handling more transactional decisions, confidence in the information being used becomes increasingly important, IAB Tech Lab said.

To address that issue, AAMP 2.3 integrates the IAB Diligence Platform and SafeGuard Privacy directly into the Buyer Agent, helping organizations embed privacy diligence into agent workflows. Enhanced pricing guardrails also improve the accuracy and integrity of transaction data, IAB Tech Lab said, creating greater confidence for buyers and sellers as agentic advertising moves into production.

Beyond that, the IAB Tech Labs reported that Agentic Audiences are now ready for fully programmatic and agentic transactions, extending standardized agentic workflows into audience activation.

New features and developments in AAMP 2.3 include:

• Enterprise-ready deployment through Amazon Bedrock and Databricks.
• Deterministic negotiation guardrails with proven end-to-end real negotiation.
• Server-side trust verification on every price-moving path.
• Support for Meta buying.
• Google Ad Manager reporting integration.
• IAB Diligence Platform and SafeGuard Privacy approval gate integrated into the Buyer Agent.
• Enhanced pricing guardrails that improve pricing accuracy across Buyer and Seller Agents.
• Any path that commits spend is deterministic and provable with human approvals outside of value-based thresholds.
• Inventory availability is always based on real, not derived, numbers.
• Fully conforming to the OpenDirect open standard and validated against the spec.
• Deals Sync API MCP Server contributed by HyperMindz.
• Content Taxonomy Parser contributed by Mixpeek, adding semantic IAB Content Taxonomy v3 classification, contextual inventory discovery and enrichment and brand-safety scoring.
• Agentic Audiences v1.0 ready for transactions.

NEW YORK—The IAB Tech Lab has announced the release of the Podcast Technical Measurement Guidelines v2.3, an update to the industry's technical framework for measuring podcast downloads, audience, and ad delivery using server-side log data.

The updated guidelines clarify how measurement should be applied across both audio and video podcasts distributed through open RSS feeds and podcast applications that rely on server-side file delivery. The guidelines are available for public comment for 30 days until August 19, 2026.

[More on the growing interest in video podcasting in the new TV Tech, Radio World and TVBEurope ebook here.]

"Measurement only works at scale if everyone is counting the same way," said Anthony Katsur, CEO, IAB Tech Lab. "These updates give the industry clearer guidance for today's podcast ecosystem and help reduce the inconsistencies that slow deals down and create unnecessary questions. That is good for buyers, publishers, and everyone responsible for reporting the numbers."

More specifically, v2.3 updates terminology from "listener" to "podcast consumer" and adds guidance around URL prefix measurement, RSS enclosure URL changes, invalid traffic considerations, and the application of different measurement window approaches.

These updates also provide clearer implementation guidance for organizations responsible for measuring podcast audiences and advertising delivery.

The change of terminology lays a foundation for work in 2027 on v3.0 guideline, which will be focusing on the growth area of streaming video podcasts. That next version of the guidelines is currently in development by the Podcast Technical Working Group, and anyone interested in supporting their development should email techlab@iabtechlab.com to join.

"Server-side log data remains the backbone of podcast measurement, and these updates reflect the continued evolution of the medium," said Hugo Martel, senior vice president of podcast and content delivery, Triton Digital. "Clearer guidance for video podcast measurement is a welcome addition, helping the industry adapt as podcast consumption expands across formats while giving publishers and advertisers greater confidence in the insights they rely on."

In releasing the new version, the IAB Tech Labs also noted that the podcast ecosystem continues to rely heavily on server-side log analysis because most podcast applications do not provide client-side playback confirmation yet. The updated guidelines help members reduce measurement discrepancies, better account for video podcasts, improve the handling of duplicate downloads and platform-driven anomalies, and promote more consistent reporting across the marketplace. For buyers, the guidance strengthens confidence that reported downloads, audience, and ad delivery are being counted consistently. For publishers, hosting providers, measurement vendors, and platforms, it provides clearer implementation guidance that supports a more trusted podcast advertising marketplace.

"These updates give the market more clarity around how podcast audiences and ad delivery should be measured, which ultimately benefits everyone relying on those numbers," said Robert Freeland, founder & CTO, Podtrac. "Our industry depends on trusted measurement that everyone can understand and apply consistently. These updates help bring that consistency."

The Podcast Technical Working Group led the development of Version 2.3 through industry collaboration and member input. IAB Tech Lab encourages publishers, platforms, measurement providers, and other stakeholders to review the draft and provide feedback during the public comment period before the guidelines are finalized.

WASHINGTON—ATSC has completed a major revision of its A/85 Recommended Practice: Techniques for Establishing and Maintaining Audio Loudness for Digital Television, marking the first comprehensive update to the industry reference since 2013.

ATSC said the revision, which expands the guidance beyond traditional television to address today's hybrid broadcast and streaming environment, is designed to help media organizations comply with loudness requirements and maintain a high quality viewing experience as they continue to transition toward IP-based and hybrid broadcast-broadband delivery models.

"As audiences increasingly consume content across both over-the-air and streaming platforms, maintaining a consistent listening experience has become more important than ever," said Madeleine Noland, president of ATSC. "This update to A/85 gives the industry practical, contemporary guidance that reflects today's production and distribution workflows while preserving the high-quality viewer experience broadcasters have worked to deliver for many years."

The newly revised ATSC Recommended Practice modernizes the document with numerous technical clarifications and introduces two important new annexes:

• Guidance for establishing and maintaining consistent loudness for streaming media services using both metadata-based and non-metadata-based audio codecs.
• A new Loudness and True Peak Quick Reference designed to simplify implementation for engineers and content providers.

More specifically, the revised A/85 Recommended Practice provides recommendations for audio measurement, monitoring, production, metadata management, dynamic-range control and loudness management throughout the content creation and delivery chain. By incorporating lessons learned from more than a decade of implementation, as well as addressing emerging streaming workflows, the document helps ensure consistent audio presentation regardless of how viewers access content, the ATSC reported.

As broadcasters await a decision from the FCC to shut down the current ATSC 1.0 broadcast format, the industry’s leading lobbyist is reiterating its support for ATSC 3.0, (aka “NextGen TV”).

Since last October, when the FCC voted on a proposal to determine a date when to sunset ATSC 1.0, debate has swirled around the timing of the shutdown and what consumer protections will be in place to ensure viewers don’t lose access to free over the air broadcasting. The commission is expected to announce a final decision by the end of 2026.

The NAB, which has promoted NextGen TV as a way for broadcasters to better compete in the increasingly complex TV landscape, told the FCC six months ago that continuing uncertainty over the lack of a date is hampering progress.

“The record developed here confirms that the Commission’s central task is no longer to debate whether NextGen TV is worth pursuing—stakeholders across the ecosystem recognize that it is—but to decide whether the transition will be allowed to succeed through an orderly, coordinated framework, or instead be stranded indefinitely in a regime of regulatory uncertainty and half-measures, all to the detriment of the viewing public,” the NAB said in comments filed with the commission in February.

Currently approximately 76% of U.S. households can receive a NextGen TV signal, according to the ATSC. In April, Pearl TV Group, a consortium of broadcasters and tech suppliers, announced the launch of an initiative to develop consumer converter boxes that could retail for under $60.

The association has also launched a campaign to help preserve live sports on free over the air TV, again noting the increased competition from streaming giants.

The ability to access live sports over free TV, competition from Silicon Valley and the very survival of broadcasting were tied together in NAB’s latest blog. The association also took aim at viewers who criticize the content protection aspects of ATSC 3.0, with many claiming that certain devices on the market don’t carry the necessary software to decode DRM-protected signals.

“ATSC 3.0 includes security and service-protection mechanisms as part of its technical framework, just as modern communications and entertainment platforms routinely protect their content and distribution systems, the NAB said. “There is an important reason for these protections. Broadcasters invest substantial resources to secure sports, entertainment and other high-value programming. They also invest every day in local journalists, meteorologists, production professionals and the technology needed to keep communities informed and safe.”

“Without reasonable safeguards, unauthorized businesses can capture local stations’ signals and resell them at scale without permission or compensation,” the association added.

NAB also criticized the possibility that the broadcast industry could be saddled with outdated technology, impacting its competitiveness.

“Requiring broadcasters to operate a decades-old standard forever would effectively make free, over-the-air television the only major communications platform that is never permitted to modernize,” it said. “That would not protect viewers. Over time, it would leave viewers with an increasingly outdated service while streaming platforms, wireless providers and global technology companies continue to innovate.”

Hitomi Broadcast will introduce Spectra, a new HDR color verification tool as well as its Matchbox Panorama timing solution at IBC2026, Sept. 11-14 at the RAI Amsterdam. Expanding its capabilities beyond timing and synchronization, Spectra helps engineers confirm that color remains accurate as pictures move through complex production and distribution routes, the company said.

Live workflows now carry more formats and versions through the same facility, including SDR and HDR outputs from a single production. As signals pass through converters, routers, processors, LUTs and software workflows, one configuration error can leave the program technically wrong even when the picture looks acceptable during initial checks.

“In the pressure of set-up, errors in a video source can be missed because there is a recognizable picture,” said Russell Johnson, Director at Hitomi. “If the color path is wrong, that problem can travel through the workflow and affect the final program.

“Engineers are dealing with more sources, more formats and more delivery paths than ever before,” Johnson added. “With MatchBox, we made timing checks fast, objective and simple. With Spectra, we are applying the same thinking, giving teams certainty that the image is being handled correctly before it reaches the viewer.”

Hitomi’s color verification solution generates a defined set of test colors at the source, sends them through the normal program route and analyzes them at the end. By comparing the received colors with the expected result, it can highlight incorrect LUTs, unexpected conversions and routing errors between SDR and HDR paths.

That gives engineers a fast, objective check which reduces reliance on visual judgement alone and helps catch configuration errors before they become visible on air, according to the company.

MatchBox Panorama will also make its IBC debut following its launch at the 2026 NAB Show in April. Matchbox provides a wide view of timing throughout the entire production workflow of a live broadcast. Panorama brings timing measurements from across complex production workflows into one central view, helping teams identify where delay is being introduced across facilities, remote production and software-based environments.

MatchBox Panorama is a standalone software product designed for larger production environments. It is already proven within the Grass Valley AMPP ecosystem, with further integrations with other manufacturers to be released soon.

Hitomi will be in Stand 10.A40 during the show.

For most of broadcast history, captioning was treated as a metadata problem. QC systems checked whether caption data was present, whether files were correctly formatted, and whether character encoding was valid. If a CEA-608 or CEA-708 stream was embedded and a sidecar file — SCC, SRT, WebVTT — was properly formed, the asset passed. Whether the captions accurately reflected what was spoken was largely outside the scope of automated review.

FCC requirements in the United States and emerging mandates across Europe have moved from nominal compliance gates to substantive quality standards. Caption files that pass every technical check can still fail on accuracy, synchronization, or readability.

What broadcast and streaming organizations need is content-level validation: verifying that captions are accurate, properly timed, readable, and ready for multiplatform delivery. Captioning is becoming part of the broader media intelligence layer — one that evaluates a caption track against the content it accompanies, treating accuracy, timing, readability, and compliance as properties the system actively measures.

Caption Accuracy Starts With the Audio Track
The practical difference between metadata validation and content validation shows up in what each one misses. A traditional QC pass confirms that a caption file is present and well- formed. It does not detect dialogue that was misheard during transcription, lines that were omitted, or text that lags consistently behind speech — all failure modes that reach viewers and, increasingly, regulators.

Content-intelligent captioning systems work directly with audio. Modern automatic speech recognition (ASR) models transcribe spoken dialogue from the audio track, producing a reference against which existing captions can be checked, or generating a new track directly. Current-generation ASR achieves word error rates below 5% on standard broadcast dialogue — comparable to experienced human transcribers, and substantially lower than error rates produced under the time pressure of manual captioning at scale.

Accurate transcription addresses what is said; alignment addresses when it appears. AI alignment engines analyze audio waveforms to synchronize caption timing against actual speech, accounting for pace variation and pausing that fixed-offset methods miss. Captions that drift from dialogue constitute a real accessibility failure, and automated alignment catches those errors systematically across an entire content library. These systems can also surface compliance risk before delivery, flagging assets where timing drift, word error rate, or reading speed exceeds regulatory thresholds.

How Captions Render on Screen
A caption that is correctly transcribed and timed can still be difficult to follow if segmented poorly. Breaking mid-phrase or mid-clause forces viewers to piece together meaning across display windows. This presents a functional problem for all audiences and a more significant one for viewers with hearing impairments who rely on captions as their primary communication channel.

Rather than breaking text at fixed character counts, machine learning models identify natural language boundaries, such as clause endings, breath pauses, and semantic units, then segment accordingly. The result is captions that read more naturally. Emerging standards reflect this: quality evaluation is increasingly extending from file validity to content readability, including reading speed, display duration, and caption segmentation.

A complete evaluation also requires reference to the video frame. Text that covers a speaker's face, obscures on-screen graphics, or overlaps burnt-in text creates problems that fall outside the scope of transcription-level review. Managing visual placement has traditionally required frame-by-frame manual review or post-production adjustment — both slow and unsystematic at the scale modern workflows demand.

Video analysis integrated into current captioning platforms detects faces, on-screen graphics, and critical visual elements, then adjusts caption positioning automatically. These tools can also prevent captions from spanning scene-change boundaries, a source of visual discontinuity invisible to metadata validation. The caption track is evaluated against the full audio-visual context of the content it serves — a quality assurance step that operates where file-level checks end.

From One Validated Track to Many
Once a base caption track has been validated, the same content intelligence can carry through to multilingual delivery. Machine translation pipelines generate multilingual versions from that source track without a proportional increase in localization effort. Additionally, systems incorporating large language models can preserve timing, segmentation logic, and reading-speed compliance across the target language, so translated tracks inherit the quality properties of the source without a separate QC cycle.

Broadcast, OTT, and streaming platforms each impose distinct caption format requirements, and a caption track that passes QC for one delivery destination may fail for another. Generating and validating multiple output formats — SCC, WebVTT, TTML, and others — within the same pipeline means format-specific compliance is confirmed once, upstream, before distribution splits across platforms.

Accuracy That Compounds With Use
One persistent limitation of traditional captioning pipelines is that errors recur without systematic correction. When a captioning process mishandles a recurring term, such as a character name, an athlete, or a brand, that error propagates across multiple assets with no mechanism to resolve it at the source.

Content-intelligent platforms address this through a continuous learning loop. When operators review and correct AI-generated captions, those corrections are captured and used to fine-tune the underlying model. Over successive production cycles, the system becomes progressively more accurate for that organization's specific content mix, speakers, and terminology. This provides a meaningful advantage over static vendor relationships, where the same errors resurface without correction.

Moving Quality Decisions Upstream
These capabilities move captioning from a production checkpoint into a media quality system. Content-intelligent workflows generate structured, validated caption data that feeds directly into MAM systems, localization platforms, and distribution pipelines. The caption track arrives at each stage as a verified asset, ready for use without additional QC. That changes where quality decisions happen. Compliance risk is surfaced before delivery.

Multilingual tracks inherit the quality properties of the source. Format-specific requirements are confirmed once, before distribution splits across platforms. The underlying shift is from discovering caption failures at the point of delivery, where correction is costly and timelines are unforgiving, to catching them at the point of production.

NEW YORK—In an important development that will improve ad planning and measurement by establishing standardized definitions for digital video product types and their advertising formats, the Interactive Advertising Bureau (IAB) has released the Redefining Media Types (RMT) Standard for public comment.

Developed with IAB Tech Lab, the standard is open for public comment from brands, agencies, publishers, ad tech partners, networks, and other industry stakeholders through August 8.

“As the video marketplace has expanded across platforms, formats, and viewing experiences, the industry needs a more consistent way to define and classify digital video environments,” said Jamie Finstein, vice president, Media Center at IAB. “The Redefining Media Types Standard is intended to give buyers, sellers, publishers, and platforms a shared, future-proof language that improves planning, execution, and measurement across the entire ecosystem.”

“Many of the technical systems supporting digital advertising still rely on inconsistent or outdated classifications for video,” IAB Tech Lab CEO Anthony Katsur said. “By partnering with IAB on this framework, we can help connect these definitions to the technical standards and infrastructure needed to support adoption across the industry.”

The RMT Standard is aims to create comprehensive, standardized definitions for digital video product types and their associated advertising formats, including connected TV, online video, social video, FAST, video podcasting and retail video. The definitions consider channels, screens, context and ad formats, with the goal of serving as an authoritative guide for media agencies, publishers, networks, technology partners, and brands.

The standard addresses a core problem in video advertising: legacy media classification terms were built to describe distribution technology and business models, not consumer experience.

For brands and agencies, inconsistent definitions can lead to misaligned planning strategies, incomparable measurement across platforms, and media investments that do not reflect the intended viewing environment. For publishers and platforms, inconsistent terminology can create confusion around inventory packaging, monetization, and buyer expectations. For ad tech and measurement providers, the lack of standardized classification makes it more difficult to support interoperability and consistent reporting across systems.

The IAB noted that the RMT Standard provides a two-layer classification system designed to support both strategic planning and operational execution.

The first layer organizes video advertising environments into four macro buckets grounded in consumer viewing experience, including “Lean Back Viewing”, “Personal Screen Viewing” and “Passive and Communal Viewing.” These buckets are based on how a viewer is cognitively and physically oriented to the screen, rather than the technology delivering the content or the business model funding it.

The second layer applies binary impression-level attributes that allow individual impressions to be classified with precision across platforms and devices, including:

• Sound state
• Skip-enabled versus completion-required
• Full-screen presentation
• Addressability
• Availability of signals
• Measurability
• Device
• Ad Formats

This operational layer gives planners, buyers, measurement vendors, and ad tech platforms a shared set of signals that can be used at the point of transaction, the IAB explained.

Together, the two layers support both planning and technical execution. The macro buckets give the industry a shared language for strategy and cross-platform planning, while the operational attribute layer provides a framework for impression-level classification that can be encoded into OpenRTB bid requests and Project Eidos taxonomy fields.

The framework is intended to create clearer expectations and more consistent communication across the buy-side, sell-side, and technology ecosystem by:

• Helping brands and agencies align media investment with the intended consumer viewing experience.
• Giving publishers and media owners more consistent ways to package and describe inventory.
• Supporting more interoperable reporting and measurement across platforms.
• Providing ad tech and measurement providers with standardized signals that can be used operationally at the point of transaction.
• Creating a more stable standards foundation as video formats, platforms and viewing behaviors evolve, and new media types enter the mix.

A number of industry players praised the release in these statements:

• “Given the extent of change in the video marketplace, from what and where people watch to how advertisers execute ad campaigns, it was critical to come together as an industry and develop a new, contemporary video marketplace framework,” said Adam Gerber, head of strategy, Media.net. “The ambiguity and obsolescence of legacy definitions and ways of working were holding back growth and creating friction in the market. This new standard attempts to fix that and provide a common language for all marketplace participants to apply within the context of their individual businesses.”
• “With the constant innovation and increased complexity of our digital ecosystem, it is important for the industry to have consistent guiding principles in place,” said Alex Stone, senor vice president, managing director, Horizon Media. “These IAB standards are our guardrails which we will use as our progression accelerates for years to come.”
• “As streaming and cross-platform video consumption continue to evolve, premium video remains one of the most effective environments for brands,” said Michael Reidy, senior vice president, Small and Medium Business Growth, Advertising & Partnerships, NBCUniversal. “As an industry, we have an opportunity to align around clearer, more consistent standards that drive greater media effectiveness and deliver simplicity for our partners across buyers, sellers, and technology platforms.”
• “The way people watch video has changed dramatically, but the language the industry uses to describe it hasn’t kept pace,” said Colt Cheadle, senior manager, sales activation, Spectrum Reach. “As video continues to evolve across platforms, screens, and viewing experiences, establishing a common framework is essential to reducing complexity, improving collaboration, and helping buyers and sellers make more informed decisions."

The public comment period for the RMT Standard is open from July 8 through Aug. 8. IAB and the IAB Tech Lab will continue working with industry stakeholders, working group participants, and standards contributors to refine the framework and support adoption across the ecosystem.

NEW YORK—The IAB Tech Lab digital advertising technical standards-setting body has announced SupplyChain v1.1, a significant proposed upgrade to the OpenRTB SupplyChain Object, commonly known as “schain” that is designed to give advertisers and buyers a more complete view of how programmatic bid requests are generated and handled.

“This is one of the most significant transparency enhancements to the digital advertising supply chain in years,” said Anthony Katsur, CEO, IAB Tech Lab. “Advertisers deserve to understand not only who participates in a transaction financially, but also who takes full control of a given request before it reaches a buyer. By expanding SupplyChain to include technical custody, we're providing the industry with a more complete picture of the programmatic ecosystem and creating a stronger foundation for trust, accountability, and investment in the open internet.”

IAB Tech Lab also invited the industry to participate in the public comment period until August 21, 2026.

The update, developed through extensive work by the Programmatic Supply Chain Working Group and guided by the Programmatic Supply Chain Commit Group, expands the role of schain beyond the traditional payment-flow view of the supply chain.

The change will allow buyers to see not only which companies participate in the commercial flow of a transaction, but also which entities take technical custody of a bid request as it moves through systems such as Prebid, ad servers, SSAI platforms, SDKs, wrappers, and other infrastructure.

The result, the IAB Tech Lab reported, is a more complete and accurate view of the programmatic supply path. The update is expected to help buyers improve supply-path optimization, reduce duplicative bid requests, and better identify all companies involved in the programmatic transaction.

In announcing the update, the IAB Tech Lab also released statements from industry leaders across the buy side, sell side, and advertising infrastructure ecosystem voicing strong support for SupplyChain v1.1. Those statements included:

• “OpenRTB exists to make programmatic advertising more interoperable, more scalable, and more trustworthy,” said Neal Richter, VP, Amazon Ads, and Chair of the IAB Tech Lab Board of Directors. “This update is an important step forward because it gives buyers a clearer understanding of how supply is actually created and transmitted. Greater transparency is how we build a healthier marketplace and give advertisers more confidence to invest in the open internet.”
• “The open internet should be the most transparent, accountable, and efficient place for advertisers to spend money,” said Paul Bannister, Chief Strategy Officer, Raptive. “This change helps make that possible. When buyers can see both the commercial path and the technical path of a bid request, they can make better decisions, reward high-quality supply, and reduce waste caused by opaque or duplicative infrastructure.”
• “Longer supply chains are not automatically worse supply chains,” said Rob Hazan, The Trade Desk. “A longer chain that accurately discloses the parties involved in the impression is better for buyers than a short chain that hides important information. With fully traceable supply chains, the industry can finally move beyond simplistic node-counting and toward a more sophisticated understanding of which supply paths best correlate to advertiser performance and outcomes.”
• “Advertisers should not have to choose between scale and clarity,” said Chris Kane, Founder, Jounce Media. “The best supply paths are the ones buyers can understand. By expanding schain to include technical custody, the industry gets closer to a world where efficiency is measurable, duplication is easier to identify, and value-added partners can be distinguished from unnecessary hops.”

The OpenRTB Working Group considered multiple implementation approaches and recommended a model that adds custody-taking entities directly to the main schain, using the hp=0 designation when an entity is not part of the payment flow.

This approach preserves the integrity of the existing schain model while giving buyers a fuller view of technical participation in the bid request lifecycle.

The Working Group also recognized that, in many cases, schains will become longer as transparency improves. To support adoption and minimize disruption, IAB Tech Lab will provide rollout guidance recommending that SSPs and DSPs coordinate staged testing, validate parsing behavior, monitor bid health, and progressively scale SupplyChain v1.1 traffic.

The proposed update also reinforces the open and collaborative nature of OpenRTB. The specification has long served as the common language for real-time bidding across the digital advertising ecosystem, and this change reflects months of discussion among companies across the buy side, sell side, and infrastructure layers.

SupplyChain v1.1 is intended to help buyers understand three critical dimensions of a bid request: how it originated, who took technical custody of it, and which parties participated in the payment flow. Together, those signals can improve trust, reduce ambiguity, and help the market direct spend toward the most efficient and highest-quality supply paths.

WASHINGTON—Sam Matheny, CEO of newly launched Merkhet Solutions, today told a House subcommittee that the country is becoming “dangerously overdependent” on GPS satellites for delivery of precise timing and positioning data.

Merkhet Solutions is the company spun off from the National Association of Broadcasters to develop commercial uses for the Broadcast Positioning System, a terrestrial backup to GPS. In testimony before the House Communications and Technology Subcommittee, Matheny warned lawmakers that GPS disruptions from jamming, spoofing, cyberattacks or natural failures could endanger critical infrastructure including energy, telecommunications, data centers and financial services.

These “risks endanger virtually every American critical infrastructure sector, including energy, telecommunications, data centers and financial services, where a disruption to precision time can trigger grid instability, network outages and lost transactions,” Matheny said.

BPS provides a backup to GPS by leveraging the nation’s TV broadcast transmission infrastructure to deliver precise timing information. “BPS is a patented terrestrial timing and position technology that leverages existing high-power broadcast infrastructure and licensed spectrum already covering the United States,” Matheny told the subcommittee. “BPS was first conceived by my team at NAB in 2021, and you can think of it as the terrestrial equivalent of GPS.”

A potential loss of GPS would affect national security and pose an economic risk of $1 billion in losses per day, Matheny testified.

Matheny laid out five BPS advantages, including:

• An infrastructure that is already in place.
• Transmission of BPS signals from high-power, tall towers in diverse locations, making it difficult to jam or spoof at scale.
• BPS uses existing licensed spectrum.
• BPS supports unlimited simultaneous users, meaning no bottlenecks—an essential element for emergency and critical infrastructure applications.
• BPS is independent of GPS and other global navigation satellite systems, functioning even when GPS is compromised.

Congress can help advance the speed and scale at which BPS can begin offering reliable GPS backup service, Matheny said.

“First, Congress should help accelerate BPS installation and operations through funding for traceable time, station hardware, calibration and ongoing network operations and monitoring,” he said.

Congress also “should support and work” with the Trump Administration in designating a lead agency to “expedite the activation of BPS and other complements to GPS,” he said.

“Finally, Congress should encourage the Federal Communications Commission to complete the important work it has already initiated on ATSC 3.0,” Matheny said. “In addition to the significant benefits to television viewers, including upgraded picture and sound and better emergency alerting, the full benefits of BPS cannot be harnessed until the FCC completes its work on the ATSC 3.0 transition.”

More information on Merkhet Solution is available on the Merkhet website.

WASHINGTON—At its annual NextGen Broadcast Conference this week, ATSC honored Julia Kenyon of the Consumer Technology Association (CTA) with the 2026 Bernard J. Lechner Outstanding Contributor Award.

“Julia is an excellent consensus builder and techno-diplomat who is a graceful and very competent leader,” ATSC President Madeleine Noland said. “She knows how to help groups get things done efficiently and collegially, which is a real art. Not only has she led multiple ATSC committees, but Julia also has a terrific sense of humor and is able to blend levity with the serious nature of standards work. She is always curious, and most recently has been helping ATSC participants really lean into the benefits of developing artificial intelligence tools.”

Kenyon has served as Vice Chair of ATSC Specialist Group on Interactive Environment (TG3/S38), Vice Chair of ATSC Implementation on Conformance (IT-3), and Chair of ATSC Specialist Group on Management and Protocols (TG3/S33). Additionally, for more than three years, she has served as CTA’s lead technical representative for the NextGen TV Test Suite development, working not only with ATSC but as chair of CTA’s own groups that work with the test suite.

Kenyon also guided ATSC in the development of A/381, the recommended practice for use of the broadcaster application for NextGen TV.

“Julia Kenyon brings unique skills to the challenge of ensuring NextGen TVs work properly with the advanced services ATSC 3.0 broadcasts provide,” said Brian Markwalter, vice chair of the ATSC board of directors and senior vice president of research and standards for the CTA. “Besides her visible leadership in ATSC and CTA standards groups, Julia directs the TV testing program that backs the NextGen TV logo. CTA commends Julia on this recognition of all she has done for ATSC and the industry.”

“Julia is an exceptional contributor to ATSC 3.0,” added Dr. Paul Hearty of Technology Advisors, an ATSC board member and ATSC Technical Group 3 (TG3) chair. “She leads and contributes to standards and compliance development both in ATSC and in CTA, covering the spectrum from origination of services at broadcast to consumption at consumer devices. She maintains balance, fairness, and technical rigor—as well as humor—throughout.”

The Bernard J. Lechner Outstanding Contributor Award is given each year to an ATSC member whose technical and leadership contributions have been exemplary.

With the Federal Communications Commission rules for an auction of at least the congressionally mandated 100 MHz of C-band spectrum expected as soon as July, many broadcasters had a laser-beam focus on how best to proceed with signal contribution and distribution alternatives during the 2026 NAB Show.

A breakfast event organized by The Hive Group, a public relations and creative agency headquartered in McLean, Va., on behalf of LTN, shed a great deal of light on the issues and alternatives from both the broadcaster and vendor points of view. For the purposes of this column, I’ll focus on the former.

Brad Cheney, vice president of field operations and engineering at Fox Sports, moderated a panel discussion about the challenges of living with less C-band spectrum. Panelists included David Johnson, senior vice president of technology at The Walt Disney Co., Alastair Hamilton, senior vice president of distribution, engineering and architecture at Fox, and Ken Fuller, vice president of distribution and technology operations at Paramount/CBS.

While video of the event posted to YouTube is available, panelists made several points worth calling attention to here.

There are multiple ingredients to success, including quality, reliability and availability, that must match what broadcasters have today in C-band. What each broadcaster ultimately chooses to do will include a mix of technologies. “There is not one silver bullet solution that gives us what we have today,” Fuller said. Finding what’s right will require “a testing curve” and a “learning curve.”

Matching C-band reliability is a big job. As things stand today, broadcasters have 99.999% C-band reliability. Disney has a lot of experience using non-satellite fiber IP and the public internet. That provides it with a good basis for comparison with C-band. “The primary challenge there is, it’s not five 9s,” said Johnson. “When you think about five 9s compared to four 9s, that’s four minutes difference in a 30-day period.” That translates into a “significant difference in quality and reliability that we need to solve for.”

Packet recovery via the internet is concerning. Some alternatives to C-band involve multiple transport paths, such as Ku-band with internet backup for dropped packets. After looking at nearly 200 major markets, Fox found ISP internet outages to be “quite alarming,” said Hamilton. “Some major markets were down for hours and hours.”

Distribution to small MVPDs will be a challenge. Taken together, Disney, Fox, Paramount/CBS, Warner Bros. and other major broadcasters deliver more than 10 Gbps of content to MVPD partners. That’s not a problem for the largest players with fiber connectivity. But the 10% of MVPDs that are smaller operators is “the bit that worries me,” said Hamilton. “I think we are going to have to get creative to service those.”

Opex reimbursement will be key. Unlike the last C-band auction, maintaining service won’t simply be a matter of replacing capital equipment. Recurring operational expenses for alternatives to C-band will be a major factor. “The blanket statement…is you [government reimbursement funds] will have to pay for our Opex for 10 years,” Fuller said. “Now, what does that mean? We don’t know yet.”

We will be holding a TV Tech Talk webinar July 29 on the ramifications of the C-band auction and available alternatives. Rebecca Hanson, director-general of the North American Broadcasters Association, will be our featured speaker. I am moderating.

NEW YORK—As media companies face growing problems with AI bots and crawlers, the IAB Tech Lab has issued guidance that is designed to help publishers and content owners better evaluate and manage how non-human agents, including AI systems, access their content as they work to adopt the Tech Lab’s CoMP API framework for managing content crawling.

The new guidance, which is now available for public comment until June 26, 2026, outlines different approaches content owners and publishers can take to inform access from non-human user agents with the aim of helping the ecosystem make more informed decisions alongside the adoption of the CoMP API V1.

“Giving content owners clear, practical guidance is key if we want adoption to move forward in a meaningful way,” said Anthony Katsur, CEO, IAB Tech Lab. “This work helps simplify a complex area so companies can make decisions that fit their business while supporting a more sustainable marketplace.”

The IAB Tech Lab noted that following the release of the CoMP API V1, it became clear that many content owners and publishers have not yet developed formal strategies around their approach to bots and crawlers, which sit outside the scope of the API itself.

To address this gap, the CoMP Working Group developed this guidance to outline the range of available approaches and the advantages and trade-offs of each strategy. This gives stakeholders a clearer understanding of how to manage access from all non-human traffic, including AI systems in a way that aligns with their business goals.

More specifically, the guidance is designed to support the adoption of the CoMP API by helping content owners navigate an area that can be operationally complex and resource-intensive and is aimed at non-technical leadership to give them the questions they need to ask.

Those questions will ultimately help them understand the value and hard costs associated with each lever they pull. With clearer direction on these strategies, organizations can make more confident decisions, reduce risk, lower their operating cost, and operate more efficiently as they engage with AI systems. Establishing these strategies is also critical to enabling partnerships between AI systems and content owners, which are necessary to build a sustainable and scalable content marketplace.

A number of industry participants involved in the development of the guidance also emphasized the importance of clarity and practical direction as the ecosystem evolves.

“Content owners are being asked to make important decisions quickly, often without clear frameworks,” said Shailley Singh, EVP & COO, IAB Tech Lab. “This guidance helps break down the options so they can choose an approach that aligns with their goals.”

“The AI revolution has caught many publishers with their front doors wide open, essentially leaving the lights on for bots and crawlers to pilfer intellectual property.” added Scott Messer, principal & founder, Messer Media, “This IAB Tech Lab guidance is the essential roadmap content owners need—a practical framework to navigate the complex maze of decisions, tech, and tools available to protect their business. By empowering publishers to identify who is really there, this guide helps them distinguish between a value-driving 'ally' and a resource-draining 'extractor'. Managing AI bots is no longer just a technical background task; it is a critical business strategy for protecting what you’ve built and restoring a fair exchange of value for your content.”

Similarly, Dave Bellous, vice president of strategy, Metal Toad, explained that “non-human traffic now dominates most of the open web, and AI agents and crawlers are steepening the curve. Blanket bot-blocking is no longer a useful strategy. For publishers, advertisers, and ad-tech alike, distinguishing beneficial automation from invalid traffic through graduated, standards-based controls has become a baseline requirement. The Bot and Crawler Guidance from IAB is a much-needed tool in crafting a modern web strategy.”

Tom Koch, head of sales, ads and marketing ecosystem at TwelveLabs also highlighted the importance of the guidance in addressing the problem of bots and crawlers: "As AI agents increasingly serve as proxies for consumers, publishers and platforms need clearer frameworks for transparency and control. The crawler management framework is an important step toward giving content owners greater visibility into how their content is accessed and used. TwelveLabs is proud to contribute as this work is foundational to ensuring video, the richest form of data, is no longer overlooked in how AI engages with the web."

The guidance was developed by the CoMP Working Group, with public comment providing an opportunity for industry feedback ahead of finalization. IAB Tech Lab will continue working with members to support implementation and encourage adoption of both the guidance and the CoMP API.

IAB Tech Lab invites the industry to participate in the public comment period until June 25, 2026. To review the guidance, https:///iabtechlab.com/botmanagement/.

VIENNA—Big Blue Marble has announced that its Nakolos platform is the first end-to-end 5G Broadcast solution worldwide to implement the complete feature set introduced with 3GPP Release 19, achieved in collaboration with ecosystem partners Bitstem, TRedess and SYES.

The milestone follows two years of active standardization contributions with organizations including the European Broadcasting Union and Broadcast Networks Europe, and for the first time enables broadcasters and broadcast infrastructure providers to validate and deploy all major Release 19 enhancements in real-world environments, Big Blue Marble said.

U.S. broadcasters are also considering the use of 5G in ATSC 3.0, with many low-power TV broadcasters advocating a switch from ATSC 1.0 to 5G Broadcast after 1.0 sunsets.

Built on a carrier-grade, 3GPP-native architecture, Nakolos has evolved continuously from Release 14 through Release 19, according to Big Blue Marble. The platform now supports a complete set of new capabilities that directly address the economic and operational realities of 5G Broadcast rollout, including Time Frequency Interleaving (TFI), which enables the reuse of existing transmission sites while improving signal robustness; CAS-Muting functionality, which allows existing DVB-T2 infrastructure to be repurposed for 5G Broadcast transmission, substantially reducing initial deployment costs; and support for the new early-deployment frequency bands B112, targeting the U.S. market, and B113, targeting Europe and other global markets.

In combination with Release 19-compatible transmitter solutions from TRedess and SYES, and the new Bitstem 5GR receiver platform, released in conjunction with this announcement, customers can now validate and deploy complete interoperable 5G Broadcast chains under real operating conditions rather than in isolated proof-of-concept environments.

“Release 19 represents a concrete step forward for commercial 5G Broadcast, not a future promise,” said Johann Mika, chief innovation officer at Big Blue Marble. “The features introduced in this release give network operators a credible path to cost-efficient deployments using infrastructure they already have. With Nakolos, they can begin that transition today, ahead of the first generation of commercial 5G Broadcast-enabled consumer devices.”

Devices should be commercially available within the next few years, said Big Blue Marble, which is positioning Nakolos “as the platform for operators who need to be infrastructure-ready before mass-market adoption begins.”

“LPTV has discovered a path for the future; it is time for full power to find a path of its own. Then again, imitation is the sincerest form of flattery. —‘SuperFrank” Copsidas, Chairman and Founder, LPTV Broadcasters Association

To the editor of TV Tech:

This is in response to Mark Aitken’s op-ed posted on May 14, Op-Ed: Stop the False Choice—5G Broadcast Can Ride Inside ATSC 3.0, and We Can Deploy Now.

There is no false choice. Mark Aitken’s public acknowledgment of 5G Broadcast’s real strengths—its native alignment with mobile ecosystems, familiar tooling, and clear potential for reaching everyday phones—is refreshing. Still, the situation for Mark and the dedicated team at Sinclair/ONE Media is understandable.

They have invested years of sincere engineering effort into ATSC 3.0, and watching it struggle for relevance in a mobile-first world must be exhausting. The Op-Ed reads less like a confident vision and more like a heartfelt plea to keep the dream alive through increasingly complex workarounds. When so much has been invested, letting go is painful. But good intentions do not make the hybrid proposal practical.

The Time-Slicing Compromise Is a Sad Technical Patch
It is unfortunate to see talented engineers spotlighting three delicate scheduling “knobs”—CAS muting cycles, 5 ms frame alignments, and bootstrap timing promises—as if they represent breakthrough innovation. In reality, this is a fragile hack: two mismatched waveforms awkwardly sharing spectrum, complete with guard times, drift compensation, and coordination overhead that reduce efficiency and introduce real operational risks.

The small-scale Castanet pilots are admirable as lab efforts, but the use of ATSC 3.0 in Castanet is essentially a bandaid solution until 5G Broadcast is fully licensed and available. Presenting this as ready for broad deployment feels like wishful thinking born from necessity rather than strength. Much creativity is being spent gluing incompatible systems together instead of pursuing cleaner solutions.

The “Chips in Phones” Claim Deserves Gentle Honesty
The repeated emphasis that ATSC 3.0 mobile receivers are ready today comes across as more hopeful than realistic. Saankhya/Tejas demodulators exist in niche Indian reference designs, yet mainstream consumer smartphones remain untouched. Full receiver integration—antennas, RF front-ends, power management, and usable software—stays confined to controlled demos, not products people actually buy and carry.

Meanwhile, 5G Broadcast benefits from riding inside the cellular modems already present in billions of phones. The community continues to hold onto “we built some tablets” stories while the broader ecosystem has moved on.

The India D2M Hope Feels Like a Distant Lifeline
Reliance on India’s government-backed trials to generate global momentum and open the stubborn U.S. market for ATSC 3.0 is understandable. India’s unique policy environment and genuine need for low-cost solutions are real. What the Op-Ed does not mention, however, is that India’s largest wireless carrier, Jio, is actively involved in 5G Broadcast trials nationwide together with Prasar Bharati, India’s public broadcaster. Jio’s 5G Broadcast trial in Delhi, for example, is testing delivery to smartphones for both broadcast TV and public warning notifications.

Expecting India’s ATSC 3.0 efforts to magically overcome America’s carrier-controlled ecosystem, regulatory gridlock, and consumer apathy toward broadcast tuners is more poignant than persuasive. It reads like a last best hope rather than a credible strategy and does not fully reflect what is actually happening in India or Brazil.

The Phased Plan Reflects Deep Investment, Not Momentum
The three-phase roadmap—scale today’s limited ATSC 3.0 datacasting, publish yet another coexistence profile, then hope India delivers devices—feels less like bold progress and more like a holding pattern to protect existing infrastructure. After all these years, broadcasters are still being asked to wait for meaningful mobile datacasting wins.

In the end, Mark’s sincerity and the solid technical merits ATSC 3.0 offers for home and portable reception are not in doubt. But it is unfortunate to watch talented people defend such convoluted hybrids and optimistic projections when the mobile world has already chosen its direction.

True progress in broadcast datacasting will come from technologies that meet consumers where they are—inside their everyday phones—rather than asking them to embrace yesterday’s compromises. The ATSC community deserves better than fighting these rearguard actions. They deserve a graceful evolution.

Mounting demand for a next-generation video streaming solution that surpasses the latency and unidirectional limitations imposed by the currently dominant streaming architecture is generating strong support for a new standard known simply as "MOQ" (Media over QUIC).

While by all accounts, it will take at least a few more months before the Internet Engineering Task Force finalizes the MOQ specifications, there are now multiple projects underway allowing producers to try out this new multidirectional, multi-latency approach to streaming.

“There’s a buzz and excitement in the air about MOQ we’ve never seen before,” says Will Law, chief architect for the cloud technology group at Akamai and a leader in the IETF MOQ initiative.

HEIGHTENED INTEREST AT NAB
This was evident at the recent NAB Show where MOQ demos abounded on the exhibit floor and an overflow crowd filled the large meeting room devoted to the NAB’s first-ever session on the standard. Entities announcing infrastructure support for MOQ included public CDN operators Broadpeak, CacheFly, Cloudflare, and CDN77 as well as cloud compute platform providers Akamai, Amazon Web Services (AWS) and Oracle Cloud Infrastructure (OCI).

Streaming software system suppliers demonstrating delivery of payloads and advanced features over MOQ-enabled facilities included Ateme, Bitmovin, EZDRM, Nomad Media, Norsk Media, Oracle Media, Synamedia, Red5 and Wowza,.

While proprietary real-time streaming systems supporting video conferencing and a host of other applications have been around for several years, MOQ is meant to satisfy the need for a standardized, ubiquitously available two-way superhighway over which video flows in any direction at any scale with latencies attuned to specific use-case requirements. That’s why Red5, a successful provider of a highly scalable WebRTC-based streaming platform, is throwing its weight behind MOQ, says Red5 CEO and co-founder Chris Allen.

“WebRTC was designed as a peer-to-peer protocol, which means there’s no standard for scaling the way we do by building out clustered cloud resources,” Allen says. “MOQ was designed from the get-go as a scalable broadcast technology for the internet, which we believe will accelerate adoption of next-generation streaming.”

The foundational set of MOQ specifications, known as MOQ Transport (MOQT), marks an incompatible break with conventional streaming modes like HLS and MPEG DASH that are based on the Hypertext Transfer Protocol (HTTP). As a so-called connectionless platform, MOQT employs a simple publish/subscribe approach to streaming by signaling the start and end points of a session while avoiding the thousands of request/response exchanges that transpire between clients and servers in HTTP streaming.

QUIC is a modern transport protocol built on UDP that is designed to make web connections faster, more secure, and more resilient. It was originally developed by Google and later standardized by the Internet Engineering Task Force as RFC 9000

Moreover, the new standard provides a way to automatically tune end-to-end latencies to whatever levels meet user requirements, including real-time 200-400ms latencies that are imperceptible to humans as well as what Law calls “interactive live” at 2 seconds for use in sports betting, online casino gambling, banking and similar applications and “conservative live” supporting ironclad HD, 4K, and, eventually, 8K quality persistency at 5 seconds.

ALL YOU NEED IS CACHE
With decoding and other device rendering processes managed through leading browsers, MOQ in most instances doesn’t require client plug-in software. And depending on how MOQ-ready CDNs are designed, MOQ can also support recording live content for short-term replay and catchup and long-term storage for VOD archives and cloud DVR applications. “VOD just means my cache is big enough to hold stuff that was live a while ago,” Law says.

Paralleling MOQT development, there are other initiatives within IETF and through the closely affiliated ad hoc organization known as the OpenMOQ Software Consortium that are aimed at creating a practical operating environment for the transport protocol. They include media layer streaming formats emerging from IETF, a new client player template developed by Red5 and endorsed by the consortium, and several ready-to-deploy players, , including a MOQ-based plug-in for Bitmovin’s new multi-purpose Player Web X platform.

“We have an array of features we enable, and each is treated as an individual plug-in,” says Bitmovin product manager Jacob Arends, who describes Player X as the latest, completely rebuilt version of its popular Web X player. “From a player [configuration] perspective there’s not much more to it than that,” but with MOQ playback departing from the HTTP norms, “it takes a lot of heavy lifting on the cloud side.”

While much of the focus on MOQ has to do with overcoming the limitations of conventional B2C streaming, the protocol also needs to be accommodated in post-production playouts to producers’ broadcast and OTT affiliates, notes Gwendal Simon, senior director for video network technology at Synamedia. “We’re bringing MOQ into our Quortex PowerVu multitrack contribution management system,” Simon says.

STAMFORD, Conn.–The LPTV Broadcasters Association today sent a formal letter to FCC Chairman Brendan Carr calling for immediate regulatory action to allow low-power television to use the 3GPP 5G Broadcast standard as a voluntary transmission option for LPTV stations.

The letter urges the Federal Communications Commission to fast-track a Notice of Proposed Rulemaking in response to HC2 Broadcasting’s 2025 Petition for Rulemaking (MB Docket No. 25-168) and move expeditiously toward final rules. HC2—which owns 131 LPTV/Class A stations and four full-power stations—has been granted experimental licenses to allow two LPTV stations in Connecticut to test 5G Broadcast.

If approved, LPTV operators say they could use 3GPP 5G Broadcast to deliver linear TV, live events, emergency alerts, and datacasting directly to millions of 5G- and 6G-enabled smartphones and tablets—no additional hardware or SIM card required.

The association has been at the forefront of using 5G Broadcast as an alternative to ATSC 3.0, (aka NextGenTV), to which U.S. broadcasters are transitioning. 5G Broadcast is a direct-to-mobile platform that runs independently of any other service on a smartphone chip be it cell service, satellite, wifi, or Bluetooth.

Frank Copsidas, an early advocate of 5G Broadcast—which has garnered more support in Europe than in the U.S. so far—is chairman and founder of the LPTV Broadcasters Association and began publicly pushing for the use of 5G Broadcast in 2023 after he formed “XGN,” a startup dedicated to promoting the standard. That same year, XGN began testing 5G via LPTV station WWOO-LD in Westmoreland, N.H., which had been awarded the industry’s first application for an experimental 5G Broadcast STA.

At the NAB Show last month, another start-up, Castanet, announced the launch of a hybrid ATSC 3.0 and 5G Broadcast internet pilot network in Las Vegas. The pilot network uses ATSC 3.0 as the transport layer for 5G Broadcast in alignment with current FCC regulations and industry standards. Castanet said the deployment demonstrates how LPTV spectrum can serve as a foundational asset in next-generation internet infrastructure.

In his letter to the FCC chairman, Copsidas said broadcast TV “has been stuck in the regulatory Stone Age while cellular technology has advanced at lightning speed.”

“Recognizing 3GPP 5G Broadcast under Part 74 will unleash a major new opportunity for investment,” Copsidas wrote. “Industry forecasts show the U.S. market for 5G Broadcast services and infrastructure is poised to grow tenfold over the next five years**. It’s time to delete this outdated dichotomy and give American broadcasters — especially agile LPTV operators—the tools to capture this explosive growth while strengthening emergency communications and delivering the mobile-first experience consumers demand.”

Copsidas said that new smartphones that support 3GPP 5G Broadcast are slated to be deployed this fall and said that LPTV is the “ideal proving ground for this technology.”

“The spectrum, technology and Q3 2026 smartphone rollouts are ready,” the letter concludes. “The only missing piece is forward-looking policy.”

NEW YORK—IAB Tech Lab has announced new Attributes to describe live content and a new Substitution Macro in OpenRTB.

It has also opened up public comments on them through May 28, 2026.

The updates introduce standardized bidstream signals that help define whether content is a livestream, real-time, or a first broadcast, along with enhancements that allow more explicit communication of pricing and discounting between supply and demand platforms.

"As more live events move into programmatic channels, a total shift in strategy is needed; buyers must condense weekly budgets into mere hours," said Anthony Katsur, CEO, IAB Tech Lab. "By providing clearer signals, we're giving buyers and sellers the transparency they need to fully capitalize on ultra-premium, real-time inventory."

The update clarifies an existing field and adds two optional fields to OpenRTB and AdCOM objects that allow sellers to describe the "liveness" of content in the bid request. These fields distinguish between content that is occurring at the exact moment a bid is sent, content that is being streamed in real time but not necessarily live, and content that is in its first scheduled broadcast window. This added layer of signaling gives buyers more precise context about the nature and timing of the inventory they are evaluating.

In tandem, updates to substitution macros refine how price-related data is passed in the bidstream, specifically enabling clearer communication of discounts and net pricing back to demand-side platforms. Together, these changes improve how both content metadata and pricing signals are expressed within OpenRTB, reducing interpretation gaps between buyers and sellers.

These enhancements address growing complexity in programmatic environments, particularly with the rise of CTV and live event inventory supported by initiatives such as the Live Event Ad Playbook. As more live and near-live programming becomes available programmatically, differences in timing and format, from live sports to premieres to streaming channels, directly influence how inventory is valued. Clearer signals help buyers make more informed bidding decisions and support more efficient pricing and yield for sellers.

"Live content signals help us better understand the context of live inventory so we can deliver buyers' budgets effectively," said Rob Hazan, GM, Product Management, The Trade Desk. "This enables agencies and advertisers to better achieve their marketing goals and sellers to more effectively monetize their most valuable media assets."

The work was developed through the Programmatic Supply Chain Commit Group, with continued industry input encouraged during the public comment period, which remains open through May 28, 2026. Feedback will inform final specification updates and broader adoption across the ecosystem.

LAS VEGAS—Complaints from viewers unable to access free over-the-air ATSC 3.0 broadcast signals are giving the standard (aka “NextGen TV”) a black eye in the view of many consumers and the ATSC is using the NAB Show to address those concerns.

As broadcasters gather in Las Vegas for the 2026 NAB Show, April 19-22, the Security Authority (A3SA), member of the broadcast standards group reiterated the importance of securing ATSC 3.0 over-the-air broadcasts and said that the “vast majority” of the 40 or so NextGen TV sets available on the market are fully capable of accessing decrypted broadcast content.

The announcement comes after the Pearl TV consortium announced the launch of a campaign to develop new low-cost $60 or under NextGen TV devices in an effort to kickstart the transition from ATSC 1.0 to 3.0.

In addition to prototype boxes from DTH, Skyworth, and Zinwell, the A3SA will showcase new and existing upgrade receivers from Airwavz, MyVelo TV, and Zapperbox, to demonstrate secure and reliable delivery of ATSC 3.0 broadcast content while delivering new recording and in-home distribution options for consumers and broadcasters. Attendees can check them out at the ATSC Booth in the Central Hall (C1655)

A3SA Managing Director Joe St. Jean explained the importance of securing 3.0 broadcast signals in an age of ever more sophisticated piracy technologies that have long been a mainstay of streaming companies.

“Free, over-the-air television remains one of the most important and accessible platforms for delivering news, sports, and entertainment to American households,” he said. “Content security is a key enabler of that future, giving content owners the confidence to continue making high-value programming available on broadcast TV. We know that content piracy is a real threat and imposes multi-billion dollar revenue losses on the sports industry, particularly.

“It’s a fact that premium sports and live programming increasingly require content protection as a condition of distribution platforms and that broadcasters are competing directly with streaming platforms that have long used content protection,” St. Jean added. “ Without protection, high-value programming will migrate to subscription-based platforms. And content protection helps preserve free over-the-air television as a competitive platform for premium content.

“We’re also pleased to note that A3SA recently commissioned a focused review, conducted by a certified public accounting firm, of A3SA-enabled televisions in the market today. We confirmed that nearly 40 NextGen TV models from Hisense, Panasonic, Samsung, Sony, and TCL, comprising the vast majority of the 18.5 millions A3SA-enabled televisions sold, are fully capable of decrypting protected content, with or without an Internet connection, ensuring that consumers can reliably access the full benefits of next-generation broadcast services.”

New Receiver Innovations on Display:

• Airwavz.tv will showcase the TvXplorer Suite with decryption capabilities for A3SA-protected content. A broadcaster professional analysis tool, the TvXplorer suite’s support for A3SA’s technology protects premium content while enabling seamless delivery to authorized users. TvXplorer delivers trusted protection at scale with enterprise-level security and authentication, ensuring content stays protected from source to screen.
  
• MyVelo TV, a next-generation broadcast-first platform provider, introduces the MyVelo TV Premiere, designed to seamlessly unify free NextGen TV, streaming apps, and premium picture performance into a single experience. Built for how people actually watch TV, MyVelo TV supports all major HDR formats, including Dolby Vision, HDR10+, HLG, and Advanced HDR by Technicolor.
  
• The ZapperBox Whole-Home Gateway is available in quad-tuner, dual-tuner, single-tuner, and mini configurations to extend ATSC 3.0 signals throughout the home. Zapperbox will show a new hardware model—the first NextGen TV quad-tuner whole home gateway with Zapper Mini receivers for secondary rooms. ZapperBox will also showcase a new software release with Advanced HDR by Technicolor for dual-tuner and quad-tuner receivers.

PRINCETON, N.J.—Triveni Digital today announced that it has added ISDB-Tb capability for its StreamScope MT-70 MPEG analyzer platform. Designed specifically for Brazilian broadcasters, the solution provides comprehensive monitoring and troubleshooting capabilities for ISDB-Tb services while supporting the country’s transition to TV 3.0 (also known as DTV+), according to the company.

Triveni will showcase StreamScope MT-70 with support for ISDB-tb and TV 3.0 at the 2026 NAB Show, April 19-22, in Las Vegas in ATSC booth C1655.

In 2025, Brazil announced adoption of the physical layer of the ATSC 3.0 protocol for TV 3.0, its next generation broadcast standard.

“As Brazil transitions to TV 3.0, broadcasters need reliable, end-to-end visibility across both legacy and next-generation broadcast television services,” said Mark Simpson, president and CEO at Triveni Digital. “With StreamScope MT-70 ISDB-Tb, we’re extending our proven monitoring and analysis capabilities and empowering Brazilian broadcasters to deliver exceptional quality, quickly resolve issues, and confidently manage the complexities of operating in a dual-standard environment.”

The new version of StreamScope MT-70 seamlessly integrates with Triveni’s StreamScope Enterprise centralized quality assurance system, enabling broadcasters to monitor and analyze quality across their entire broadcast operation—from ISDB-Tb to TV 3.0 services. This unified approach is critical as Brazil enters a lengthy simulcast period where both standards will coexist on air, Triveni said.

Built with Brazil-specific support for SBTVD ABNT NBR 15603 tables and descriptors, StreamScope MT-70 ensures accurate validation and deep visibility into regional broadcast requirements. The solution is available in multiple deployment options, including rack-mount systems, software, and in the cloud, giving broadcasters the flexibility to deploy it based on their operational needs.

WHITE PLAINS, N.Y. — The Society of Motion Picture and Television Engineers (SMPTE) has released more details about the SMPTE ST 2110 IP Media Roadshow at the 2026 NAB Show, announced last month.

On Tuesday, April 21, SMPTE will hold a a first-of-its-kind, full-day in-person bootcamp, designed to equip media professionals with the practical knowledge needed to confidently design, deploy, and operate IP-based production systems.

The program runs from 10 a.m. to 5 p.m. in Rm. N252 in the North Hall of the Las Vegas Convention Center.

Grounded in real-world broadcast, live production, and hybrid environments, the Roadshow goes beyond theory — focusing on how IP media systems actually perform in the field. As the organization responsible for developing and maintaining the SMPTE ST 2110 standards, SMPTE brings a depth of expertise and vendor-neutral perspective unmatched by any other training provider, connecting specification language directly to operational practice.

“The industry’s shift to IP-based production is well underway, and professionals need more than theory — they need practical, systems-level knowledge they can apply from day one,” said Jesse Janosky, Senior Engineering Leader and ST 2110 Instructor at JPM Technology Consulting. “This Roadshow bridges that gap — grounding standards in the real-world decisions engineers face every day.”

Full-Day Program Schedule
Opening with a welcome and introduction to the SMPTE ST 2110 Working Group from Merrick “Rick” Ackermans — Director of RF and Transmissions Engineering at CBS/Paramount, Chair of the SMPTE ST 2110 Drafting Group, and a SMPTE Fellow — the bootcamp moves through six structured modules that progress from foundational concepts to hands-on system design. Jesse Janosky provides a run-of-day overview before the technical sessions begin.

• Module 1 — ST 2110 Foundations & Standards Overview (Chris Lapp, Cisco): An introduction to the ST 2110 standards suite and the foundational principles of IP-based media transport.
• Module 2 — Precision Time Protocol (ST 2059) for Live Production (Willem Vermost, EBU): A deep dive into how PTP enables deterministic synchronization across live production facilities, followed by a supplementary session on warning signs and failure modes when PTP begins to drift, led by Steve Kolta of Meinberg.
• Module 3 — Audio Over IP in ST 2110 Environments (Andreas Hildebrand, Lawo): Coverage of AES67 and ST 2110 audio transport standards, including packetization, flow configuration, MADI over IP, and practical deployment considerations.
• Module 4 — Network Fabric Design for Media (Gerard Phillips, Arista Networks; Chris Lapp, Cisco): Multicast routing, bandwidth planning, and redundancy strategies for networks carrying real-time, uncompressed media, followed by a session on identifying bottlenecks led by Cassidy Lee Phillips.
• Module 5 — Deployment and Operational Failure Points (Nestor Amaya, EVS): Identification of the design decisions and configuration errors most commonly encountered in the field, and a practical framework for avoiding them.
• Module 6 — Team Practicum: Sample RFP and System Design (Jesse Janosky & Cassidy Lee Phillips): A collaborative exercise built around a realistic RFP scenario covering client needs assessment, workflow mapping, functional diagramming, product research, and deployment partner qualification. The day concludes with team RFP presentations.

What attendees gain extends well beyond the six modules. A shared technical vocabulary, greater confidence in infrastructure decision-making, and a clearer picture of where adjacent technologies — including IPMX, NDI, Dante, and JPEG-XS — fit within the broader standards landscape are among the key takeaways. The program is suited for broadcast and media engineers, systems integrators, live and remote production teams, media IT and cloud professionals, early-career professionals, and students.

Registration is available a la carte and includes a NAB Show Floor Pass. Non-members pay $550; SMPTE members, NAB members, students, and government attendees are eligible for the $450 rate. Discounts are also available for SMPTE Education alumni.

For broadcasters that have yet to convert from Serial Digital Interface (SDI) to SMPTE ST 2110 IP production workflows across portions or all of their facilities, three new industry initiatives within and outside SMPTE bode well for accelerating the pace of IP adoption.

While ST 2110 has taken center stage as the driving force behind the industry’s ability to embrace the scaling, remote connectivity and other efficiencies of IP software technology, SDI still serves as the dominant production backbone in 82% of broadcast operations, according to the 2026 edition of Haivision’s annual survey on global broadcast tech trends released last month.

‘It’s a Pain’
As Samuel Recine, Matrox Video’s vice president for strategic partnerships, noted, “It’s not easy to migrate entire facilities to 2110.” Even as new-build requirements and aging SDI facilities unleash inevitable migrations to IP production, ST 2110 users attest to facing hurdles they would rather not contend with.

For example, when executives at a recent industry gathering were asked about their biggest challenges with ST 2110, several singled out problems with using the Precision Time Protocol (PTP) to ensure synchronization across video, audio and metadata streams.

“It’s a pain,” said Peter Wehner, executive vice president of technology operations and engineering at Mobile TV Group, which supplies mobile units for live sports and other productions. “When something goes wrong, there are different reasons every time.”

“I agree; it’s PTP,” concurred Jason Taubman, senior vice president for technology at Game Creek Video, another mobile production fleet supplier. In addition, while “we’re all in on 2110,” another big issue has to do with scaling, where managing “tens of thousands of signals is a huge challenge,” he said.

But the good news is “we’re now feeling comfortable with IP interoperability,” Taubman added. “We can cherry-pick vendors from off the shelf.”

Indeed, there’s every reason to expect the pace of ST 2110 adoption will accelerate as interoperability extends into other areas vital to usage. This includes vendor compatibility enabled by the IP Media Experience (IPMX) standard backed by the Alliance for IP Media Solutions (AIMS), the Linux Foundation-backed Media eXchange Layer (MXL) software development kit (SDK) and SMPTE’s emerging ST 2138 standard, also known as Catena.

So far, when it comes to live venue-centered production, “2110 in the field is typically limited to large deployments—big trucks, big network centers, where you need lots of streams, lots of devices,” Cobalt Digital Chief Technical Officer Ciro Noronha noted. “All those big guys are going to 2110.”

Bringing Pro AV Into the ‘MiX’
This has been a major step toward minimizing the amount of field-deployed equipment via remote connectivity over IP to core production centers. Now, thanks to IPMX, these benefits can be more readily exploited in smaller live broadcast productions as well as a vast range of other use cases that have been off limits to ST 2110, including Pro AV, corporate media and education productions that traditionally rely on High Definition Multimedia Interface (HDMI) switchers and cable for digital operations.

This year’s ISE in Barcelona demonstrated how suppliers are rapidly adopting IPMX as a software upgrade to existing ST 2110 products and as the foundation for a new generation of products that work at extremely low latencies with asynchronous and synchronous sources in compressed or uncompressed modes without requiring the use of PTP. “I call it ST 2110 made easy,” Noronha said.

At the 2026 NAB Show, Cobalt is introducing IPMX in one of its audio monitoring units along with the new blueCORE “processing box” supporting 2110 input and output gateway functionality. “Everything we do from now on will be
IPMX-compliant,” Noronha said, bringing “all the benefits [of ST 2110] without the big price tag.”

Elsewhere on the show floor, Imagine Communications is promoting features unrelated to IPMX that have been added to its ST 2110 products, but in the broader scheme, the company is highly focused on bringing the new standard into its portfolio, according to John Mailhot, Imagine’s senior vice president of product management. The company will soon obtain certification for products already in line with the standard, he said, while “others will be compatible
over time.”

For now, Imagine will concentrate on touting ST 2110-related advances like a new graphics workflow enhancement to its recently introduced XVR playout engine and an expansion of multiview capabilities in workflows under control of its Selenio Network Processor. In the latter case, Mailhot said, Imagine is leveraging technology obtained with its recent Pixel Power acquisition to “present operations people everything they need to see all their work in one solution,” including low-latency remote feeds from satellites and other sources.

Matrox, another supplier all in with IPMX, has exploited the compatibility between IPMX and ST-2110 to the fullest extent by offering each of its ST-2110-related products as a “superset” that can be deployed with software tuned to either mode.

For example, Recine said, an IP/SDI converter that’s used in a complex ST 2110 broadcast environment where all live flows must be synchronized can also be purchased in IPMX mode for conversions in business, education or other more limited production situations where PTP synchronization isn’t essential, including portions of a broadcast facility that aren’t involved in “the mission-critical part of producing live content.”

Media eXchange Layer
Meanwhile, another realm of versatility that alleviates ST 2110 usage burdens is opening with the introduction of the MXL software development kit (SDK). By creating a template for packaging video, audio and data essences as microservices in container-virtualized data centers, MXL “is a way of breaking down the barriers, not having to encapsulate 2110 every time you want to do another bit of processing in the workflow,” said Daniel Robinson, product manager for MXL at Matrox Video.

MXL has strong industry support with collaboration from the EBU, the North American Broadcasters Association (NABA) and a growing coterie of European and Canadian media companies such as CBC/Radio-Canada, BBC, France TV, RTÉ (Ireland), SRG SSR (Switzerland), SVT (Sweden), SWR/ARD (Germany) and VRT (Belgium). Extending the reach to global proportions, including the U.S., are vendor “implementers” Appear, Amazon Web Services (AWS), Grass Valley, Imagine Communications, Intel, Lawo, Matrox Video, NVIDIA, Riedel Communications and Telos Alliance.

Matrox is one of about six vendors “that have actually got it working in our product,” Robinson said. Many components in the Matrox product line were already configured to work in the containerized environment, but there is greater demand for the cost savings that come with such efficiencies in an open-source environment, especially one that avoids a drawn-out standardization process, he noted.

Hardware Control
The third initiative, SMPTE ST 2138, would expand interoperability essential to speeding the transition to IP by defining an open-source media control system that securely connects all devices pertinent to broadcasters’ IP-based production operations, regardless of whether transport is via ST 2110, NDI or something else.

This includes support for connecting everything that receives production output, as well as devices supporting data-center lighting, power maintenance and other operations, noted Chris Lennon, a SMPTE fellow serving as director of standards strategy at Ross Video, who has been a key figure behind the initiative.

“From our perspective, SMPTE ST 2138 is driven by customer demand,” Lennon said. “It’s hard to deny we have a serious problem with well over 200 proprietary control systems in operation.” The open-source OpenGear Protocol (OPG) developed years ago by Ross Video is the foundation for ST 2138, which has been greatly enhanced for today’s cloud operations with microservice-based scalability and other innovations, he explained.

At press time, five documents defining the 2138 protocol stack were slated for posting for input from the community at large, with a tentative cutoff date six months from now, depending on whether there’s enough consensus to merit the final push to standardization. It remains to be seen how broad industry support will be at this early stage, as other approaches to a universal IP device control system take hold in other industries’ forums.

“Luckily, many of them can work with the rapidly growing standards like 2110 and IPMX,” Sam Racine noted. One aspect that could be critical to broadcast industry buy-in to ST 2138 is that it is fully compatible with MXL. “We’ve done proofs of concept to show they are complementary and can work together,” Lennon said.

For many suppliers, the question of incorporating ST 2138 into their software stacks is still on the back burner. “If it’s important to our customers, we’ll support it,” Imagine’s Mailhot said. “Right now, there are a lot of things customers say they want that we’re actively doing.”

But the overall direction in broadcast production is clear. The all-out hunt is on for whatever it takes to make ST 2110 a more viable bridge from SDI to IP.

All of these new initiatives (and more) will be highlighted at SMPTE’s IP Showcase, part of the Tech Chat Theater in the West Hall during the 2026 NAB Show, April 19-22 in Las Vegas. The showcase is sponsored by AIMS, AMWA and the VSF.

Pearl TV’s over-the-air converter box survey, released last month, reveals the existence of a long-suspected viewer class.

As the industry awaits a rulemaking from the Federal Communications Commission it hopes will bring certainty to the end of ATSC 1.0 to make way for a full rollout of 3.0, Pearl TV appears to be attempting to reassure regulators with research showing over-the-air TV viewers are willing to spring for an inexpensive converter box to ensure post-transition reception.

The research, conducted by Magid and released in the “Pearl TV Over-The-Air Converter Box: Consumer Key Findings” report, asked 600 adults 25-65 years old who watch a minimum of two hours of OTA TV per week what they thought about the prospect of shelling out a few dollars for a one-time purchase of a converter “to maintain free access to local TV content without recurring monthly fees.”

Spoiler alert: Four out of five respondents would buy a converter box with basic features. That should give some peace of mind to the commission if it chooses to set a date or dates certain for a 1.0 sunset as NAB has petitioned rather than continue with a voluntary transition, albeit with fewer regulatory restrictions.

While highly pertinent to the transition discussion, the thing that caught my eye was the report identifying the “emergence of the ‘Omni-Viewer’ segment” of OTA TV fans.

Who are omni-viewers? The “tech-savvy group… who intentionally blend free local broadcasting with digital streaming,” the report said.

“Nearly two-thirds of antenna users also subscribe to streaming services, demonstrating that, for these consumers, broadcast television is complementing, rather than being replaced by, modern digital platforms,” it said.

I’ve long suspected this class of TV viewer exists. After all, I am one. I’ve also suspected TV broadcasters can take advantage of the existence of this set of viewers who are equally adept at streaming content via the internet and OTA TV. Here are three ways they can:

• Cement viewer loyalty and grow the OTA audience. Installing a rooftop antenna or one in the attic isn’t especially hard but neither is it particularly easy or convenient. (Was that really a brown recluse spider I saw in the roof rafters as I squirmed on my back across the ceiling joist?) But with OFDM-based ATSC 3.0, a simple indoor antenna may be all that’s needed for reliable reception. That may be enough for omni-viewers to spread the word to their friends and family.

• Enhance the viewing experience with interactivity. Broadcasters already have some experience leveraging both OTA and streaming delivery of television, à la Broadcast Enhanced Streaming Channels and RUN3TV-based program start over. How else might they enhance TV viewing and benefit economically? Targeted ads, QR code-triggered shopping carts and others not-yet imagined or at least made public?

• Hyper-local news and advertising content. Who needs the expense and headache of local SFNs and deploying LDM solutions if it’s possible to deliver specific, targeted news and commercials to neighborhoods, districts and other defined zones? Even to individual omni-viewers?

Bottom line: The omni-viewer has arrived. Broadcasters need to begin acting like it.

The Media eXchange Layer (MXL) has officially moved from Release Candidate to a stable production release.

The project’s steering committee has officially launched version 1.0.0 of MXL on GitHub, enabling vendors and developers to integrate MXL support into their products.

According to the European Broadcasting Union, which has been shepherding MXL to its release, the development process included alpha versions and release candidates, which were tested by EBU members and the industry. Their feedback contributed to the finalization of the stable production release. Work to update MXL’s roadmap will continue.

The EBU added it expects to see the first MXL-compatible products announced in the next few months, possibly at NAB Show.

MXL: Aligning broadcast production with software

[This article originally appeared in our sister publication TVBEurope.]

While broadcasters eagerly await an FCC rulemaking they hope brings clarity to a sunset of ATSC 1.0, the TV industry continues incremental progress on ATSC 3.0 with new technology, business and marketing developments that will play important parts on the NextGen TV stage at the 2026 NAB Show, April 18-22, at the Las Vegas Convention Center.

(Editor’s Note: This article was written prior to the Federal Communications Commission rulemaking [MB Docket No. 16-142] reply comment deadline of Feb. 18.)

Among them are the latest developments on the Broadcast Positioning System (BPS), various enhancements to the standard, addressable multicast service, datacasting business progress and the latest on the headway ATSC 3.0 is making outside the United States. These and other 3.0 developments, however, are overshadowed by any FCC movement on its pending Notice of Proposed Rulemaking aimed at the transition to NextGen TV and sunsetting the existing ATSC 1.0 digital television service.

“I think what we need to see happen is a clear sunset date,” said Robert Folliard, senior vice president for government relations and distribution at Gray Media. “Everybody knows from their own personal lives that without a deadline, nothing ever happens. I think consumer electronics, manufacturers, broadcasters, everyone needs a clear road map for us to get this done.”

Leave No Viewer Behind
Perhaps the thorniest issue obstructing bringing today’s DTV to a date-certain conclusion is 3.0’s lack of backward compatibility with 1.0. For an industry that’s built upon serving the public with free news, sports and entertainment—and relies on the ad and retrans revenue they generate—a flash cut stranding over-the-air viewers is simply out of the question.

In January at CES 2026, Pearl TV announced an effort to take on this issue with its Converter Box Initiative, a program that aims to make affordable converter devices with a target price below $60 available to viewers for their existing TVs. At the 2026 NAB Show, the business group representing seven major TV station groups will discuss the progress it’s made on the initiative since then.

“Right now, we’re pulling together the tenets of the program, which provide for set-top box makers to participate where we’ve negotiated special discounts on aspects that would otherwise commercially be higher priced without this negotiation,” Pearl TV managing director Anne Schelle said.

While such lower-cost converters may not include the full attributes of the standard available on a NextGen TV, they will ensure viewers can maintain their over-the-air service and receive “the better audio and video capabilities” of 3.0, she said.

Converter boxes meeting the program’s specifications will qualify manufacturers for special component discounts Pearl TV is negotiating that will help to keep the price down by guaranteeing volume. “Guaranteed volume means everything in the supply chain to drive lower costs,” she said.

At the show, Pearl TV will release details of the devices’ specifications, as well as the findings of a qualitative study conducted by Magid Associates to test the $60 price target against feature trade-offs, Schelle said.

Delivering a lower-cost converter today would be a challenge given the AI server-
driven demand for DDR5 RAM and the associated price spike. However, by the time final FCC 3.0 transition rules are set and implemented, it’s likely memory costs will go back down, she said.

The availability of lower-cost converters addresses one of three main questions the FCC raised in its NPRM, Folliard said. “I think if we as broadcasters were to go to the FCC and say, ‘Give us a sunset date, thank you,’ the answer is going to be ‘no.’

“But if we go in, which is what we’re doing, saying, ‘We’re going to produce a low-cost converter device that makes sure consumers are not left behind,” he said. “We’ve done consumer research that finds over-the-air antenna users today say, ‘Yeah, I would pay that price. That’s a bargain.’ We’ve addressed the DRM concerns that are out there and solved the signal signing concerns that are out there, if we can tick off each of those items, I think it’s a different story.”

Tech Developments
NAB Show traditionally gives vendors the chance to roll out their latest advancements. The same is true of those focused on 3.0 technology with exhibits in their own booths, the ATSC booth in the Central Hall (C1655), the Pilot Pavilion and elsewhere.

At the time of this writing, many of these exhibit details are unclear. However, as in year’s past, the Advanced Television Systems Committee (ATSC) is producing a tearsheet that will be available at the show to inform attendees the location of vendor booths with 3.0 technology, the times and locations of 3.0-related presentations and “all the fun stuff, the happy hours and the cool events,” said ATSC President Madeleine Noland.

ATSC’s new vice president of standards development, Luis Fausto, and Noland will present an update on ATSC 3.0 during the SBE Ennes workshop on April 22.

Sinclair will highlight its work on development of “Broadcast-to-Everything” (B2X) in the ATSC booth. “That work is essential for a variety of reasons, the biggest of which is opening up the total available market to our IP platform,” said Mark Aitken, president of ONE Media and senior vice president of Advanced Technology at Sinclair.

Work is underway at ONE Media Technologies and more broadly by ATSC to align the standard with all of the 3GPP platforms and services. Among those is enabling IP multicast via 3.0 with addressable data flows, something datacasting clients can rely upon to ensure their valuable data is only received by those to whom they intend to send it.

“The work going on right now is a bridging technology that will bring us all the way to physical layer addressing, which changes the nature of the waveform itself,” said Aitken, adding that proof-of-concept deployments are expected in the second half of the year.

ATSC 3.0 Network Design
Advancing ATSC 3.0 network design is among the projects going on at the standards organization and will likely be a topic of discussion at its NAB Show booth. “We’re working on Recommended Practices for network design,” ATSC’s Noland said.

“How many transmitters do you need? What kind of robustness do you need? We have some of that work done in A/327 already, but this is a little bit of a bigger project where you’re really thinking about, ‘How can you set up your ModCods and your towers to achieve a given goal,’” she said.

Gray Media intends to tout its efforts to leverage the 3.0 over-the-top back channel to ensure robust OTA reception.

“One of the key things we have heard loud and clear from consumers is that the 1.0 signal is not great,” Gray’s Folliard said. “It’s not robust; it’s not reliable. If you can give me a way to get a more reliable signal that I don’t lose when the wind blows, that alone may be the biggest underappreciated consumer benefit of the 3.0 signal.”

Gray has been working with ATSC and others on updating the 3.0 standard to allow what the station group is calling “recovery channels,” he said. “If you are getting an over-the-air signal and it’s all fine, and then you temporarily lose it—maybe because of the digital cliff effect—what will happen is you’ll be able to get the signal automatically via the internet.”

Calling these recovery channels a “game changer” for OTA television, Folliard said the update to the standard will enable broadcasters to deliver “a perfectly stable and reliable OTA signal to viewers.”

Much work still needs to be done, and “much of what we have done is still theoretical,” he said. “Nonetheless, it is incredibly promising and another example of why we need to push the 3.0 transition forward.”

NAB Show will also give broadcasters the chance to learn the latest advances in BPS, including what’s going on with the U.S. Department of Transportation-funded BPS testing and a realignment of NAB tech leadership to focus on the ATSC 3.0-based backup to GPS. Several papers will be presented on BPS as well as demonstrations in the NAB Pilot booth and vendor booths.

EdgeBeam Wireless, the 3.0 datacasting-focused joint venture of E.W. Scripps, Gray Media, Nexstar Media Group and Sinclair formed in January 2025 and announced later that year, will be at the NAB Show with two goals in mind: supporting its partners and talking to other broadcasters that could help it extend its 3.0 footprint, EdgeBeam CEO Conrad Clemson said.

Expanding the Ecosystem
“From the time I got here [June 2025] up until a couple of months ago, we would look at both the breadth and depth of our ATSC 3 deployments and say, ‘Wow, look at all the places we are. Isn’t this great?’” Clemson said. “Now we have a different conversation: ‘We’re trying to get an opportunity up here, and I don’t have coverage or I don’t have the depth of coverage I need.’”

NAB Show is “a great time” for EdgeBeam to start the process of expanding its coverage ecosystem, he said.

The show will also see a large contingent of broadcasters from other countries on hand to support or investigate the standard. Fresh off success in Brazil, where the ATSC 3.0 physical layer and other components of the standard were selected for that nation’s new DTV+ (formerly known as TV 3.0) standard, the ATSC organization will focus its efforts on the Americas and India, said Noland.

“We’re putting our resources there because our feeling is that in the Americas, there’s more of a clear path,” she said.

All of these 3.0 developments will occur against the backdrop of the FCC rulemaking that many broadcasters hope will bring clarity to an ATSC 1.0 sunset. For his part, Aitken is encouraged by recent Truth Social posts from President Donald Trump and FCC Chair Brendan Carr in support of Nexstar’s acquisition of Tegna, which he said demonstrate the government’s understanding of the vital role local TV broadcasters play in their communities.

“The relevance of local markets, the relevance of what we do in those local markets is increasingly understood,” he said. “Our uniqueness is distinguished by the roles we play there. We’ve now got this platform [3.0] to make a new business and strengthen our ability to serve our local communities. But we are resource-constrained [by the channel-sharing 3.0 rollout].

“There has to be some deference given to ensure the success of that service because an authorized service that cannot be received is not a service. It’s a policy failure.”

GENEVA—The HbbTV Association, a global initiative dedicated to providing open standards for advanced interactive TV services via broadcast and broadband networks, has published version 2.0.5 of its core specification.

HbbTV 2.0.5 is an update to HbbTV 2.0.4, published two years ago, and represents a significant technical advancement for hybrid and interactive television services. The update was approved at the latest meeting of the HbbTV Steering Group.

“HbbTV 2.0.5 represents an important step forward in the evolution of hybrid TV services,” said Vincent Grivet, chair of the HbbTV Association. “With formalized DRM, support for next-generation codecs such as AV1 and VVC, enhanced DVB-I integration, and WebAssembly capabilities, the specification aligns to the most recent and impacting market trends, enabling more sophisticated, secure and feature-rich services. It demonstrates HbbTV’s continued commitment to advancing the connected TV ecosystem for broadcasters, platform operators, content owners and viewers alike.”

The most notable change is the formal integration of Digital Rights Management (DRM) into the core specification.

While HbbTV devices have supported DRM for many years, this is the first time it has been explicitly defined, providing a harmonized, interoperable approach across the ecosystem. Support for at least one of the DRM systems listed in the HbbTV DRM specification published six months ago – Microsoft PlayReady or Google Widevine – is required.

This formalization is essential for enabling secure delivery of premium content and meeting the requirements of broadcasters, platform operators, rights holders, and content owners, ensuring a compelling experience for viewers.

WebAssembly support, already present to some extent in HbbTV devices via browser engines such as Chrome or WebKit, is now formally included in the specification. This allows advanced features such as efficient decoding of auxiliary video streams, including sign language services demonstrated by Catalan public broadcaster 3Cat at trade shows IBC 2025 and HbbTV Symposium and Awards 2025.

Additional web security measures have been incorporated, and support for the VVC and AV1 video codecs has been defined, although implementation of these codecs is optional. Several simplifications for implementers have also been introduced: unused features have been removed, others marked for deprecation, and some requirements relaxed to improve interoperability.

The integration between HbbTV and DVB-I introduced in HbbTV 2.0.4 is further improved in 2.0.5. The specification now clarifies how DVB-I applications associated with entire service lists can be supported, enabling platforms or service aggregators to obtain GDPR consent or agreement to terms and conditions. Implementation feedback, particularly regarding HbbTV and DVB-I integration, has resulted in numerous technical corrections being included.

The HbbTV Association plans to issue a Request for Proposals (RfP) in the coming weeks to extend its Conformance Test Suite to support HbbTV 2.0.5.

The HbbTV 2.0.5 specification and an associated explainer document are now available in the HbbTV Resource Library.

I can still remember the first time I clipped a lavalier microphone on someone for a TV broadcast. It was during my internship at AT&T Corporate Television in 1978, back when razor blades were still used for editing and the smell of hot glue meant progress.

The mic was a Sony ECM-50, a small, rugged piece of engineering that quickly became my favorite. It needed a quirky little “N” battery that you could only find in specialty stores, but it sounded beautiful.

A few months later, I met what felt like pure science fiction: my first professional wireless microphone system. It was a Sony UHF transmitter and receiver paired with that same ECM-50 element, and for the first time, I could capture sound without being chained to a cable. The audio was clear, the signal was stable, and there were no wires to trip over. It just worked.

For a long time, wireless microphones felt like magic. Today, they feel more like triage. The magic has been replaced by management. Behind every concert, broadcast, or corporate event, there’s now a quiet war being fought over invisible real estate: radio spectrum.

The Shrinking Airwaves
Wireless microphones used to have plenty of room to breathe. For decades, most systems operated comfortably within the UHF television range from 470-806 MHz. These frequencies offered the perfect balance of power, antenna size, and propagation. But that was before governments realized the commercial value of those airwaves.

The first big hit came in 2009, when the transition to digital television freed up the 700 MHz band. The Federal Communications Commission auctioned that space to mobile broadband carriers like AT&T and Verizon, shrinking the number of open TV channels available for wireless microphone use. A few years later, it happened again with the 600 MHz band, much of which went to T-Mobile. Each time, the usable spectrum for professional microphones shrank.

While those auctions raised billions of dollars for the U.S. Treasury, none of that windfall ever found its way back to the professional audio community that once depended on those frequencies. Wireless microphone users—from broadcasters to theaters to houses of worship—lost access to critical portions of the spectrum without compensation or assistance to transition. The mobile carriers that won the auctions gained valuable assets, while production teams were left scrambling to replace equipment and redesign systems at their own expense. In effect, it was a one-sided trade: Culture and communication ceded ground so commerce could expand.

What had once been an open field is now a narrow alley. In most major cities, there may be only one or two available TV channels left for unlicensed wireless microphones. The rest belong to high-power mobile networks or other licensed users. As one engineer put it, “It’s like trying to park 50 trucks in a two-car garage.”

Problems and Solutions
I recently sat down with Mike Sinclair, a professional sound designer, to chat about problems and possible solutions. He's worked on everything from live events to concerts to corporate audio and described it bluntly: “You can plan every cue, map every signal path, and test every channel, but if you don’t have enough frequencies to manage the production there’s very little you can do.”

Even when you do find enough open frequencies, it doesn’t mean it will stay quiet. Modern environments are packed with devices that share or spill into the same spectrum. Multiple digital services are now actively competing for what is ultimately the same limited bandwidth.

The problem isn’t just about congestion; it’s about unpredictability. What used to be simple “set and forget” gear now requires active management. Sound engineers who once mixed audio now find themselves either running RF scans, plotting frequency tables, and negotiating for airspace—or spending a boatload of additional cash buying wireless systems that will do the investigating and hopping for you. Every production feels like a temporary truce with chaos.

The answer is often counterintuitive. You might think throwing more power and more money at the problem would make things easier, but in many cases, it doesn’t. As Sinclair told me, when multiple wireless systems have to coexist in tight spaces, very close together—like, for example, Broadway theaters—the solution is precision, not brute force. Engineers have to be surgical, using highly directional antennas and carefully tuned devices that keep their signals tightly contained to avoid interference.

Devices Fight Back
To survive in this new landscape, manufacturers have had to reinvent their technology. Early wireless microphones operated on fixed frequencies. Modern systems can tune across wide ranges, automatically scan for open spectrum, and adjust power output on the fly.

One possible approach could be treating each microphone as a separate radio signal, using one wide channel to transmit dozens of audio streams using time-division multiplexing. In simple terms, it sends tiny slices of each audio channel in rapid succession so that multiple mics can share a single piece of spectrum without stepping on each other. Sennheiser, one of the world’s leading innovators in professional wireless audio, has been at the forefront of developing new spectrum-efficient technologies, such as Wireless Multichannel Audio Systems (WMAS).

Joe Ciaudelli, the company’s director of spectrum and innovation, explained that WMAS technology "occupies a broader bandwidth but transmits multiple audio channels within that space using time-division multiplexing. This design dramatically increases spectral efficiency, enabling dozens of microphones to operate in a single TV channel.”

Solutions like this allow both microphones and in-ear monitors to operate in the same RF channel, dynamically allocating bandwidth based on priority. A lead performer can get full-fidelity, low-latency audio, while a backstage communication channel can tolerate higher latency and lower quality. For large productions, this means far more microphones can coexist peacefully in the same space.

For high-profile events, technology alone isn’t always enough. On-site professional frequency coordination can offer productions peace of mind by managing and accounting for each frequency.

Companies like Professional Wireless Systems (PWS) provide RF management and coordination for various events, including major productions like the Super Bowl Halftime Show. Jim Van Winkle, general manager at PWS, emphasizes that their competitive edge lies in on-site experience. He notes that an experienced RF coordinator is a "game-changer," bringing invaluable knowledge for pre-planning and crucial troubleshooting if issues arise.

For smaller or budget-limited productions, advanced technology safeguards can still help avoid chaos. One such approach uses wireless transmit/receive pairs that continually search for and stand by with clean backup channels. If interference or dropouts are detected on the main channel, the devices automatically switch to that backup while beginning a new search for the next available path.

Another company that has fully embraced the need for adaptability is Wisycom, a manufacturer long respected for its RF engineering in broadcast, live performance, and location sound. Its CEO, Davide Morsiani, said RF coordination has become "one of the biggest challenges in modern production—not because engineers lack skill, but because the spectrum itself is shrinking and unpredictable. Every location behaves differently, and even the same venue can change throughout the day. Our goal is to give users visibility and flexibility across the widest possible tuning range, so they can adapt instantly rather than rely on luck."

And one final approach that should be mentioned, despite its quixotic nature, would be for the FCC to actually begin policing the use of approved frequencies, as it's clear that everyone isn’t playing nicely in the sandbox.

Unified Voices
Technology alone isn’t enough. The professional audio industry has also learned that it needs a stronger and more unified voice in the policy arena. Shure led the formation of the Wireless Microphone Spectrum Alliance (WMSA), bringing together manufacturers, engineers, and end users to create a coordinated front at a time when spectrum access continues to shrink.

Shure has been deeply involved in the development of regulations in the United States and other countries, with spectral efficiency as the center point of its advocacy. According to Prakash Moorut, Shure’s global head of spectrum and regulatory affairs, WMSA now provides a platform for the industry to proactively educate policymakers about preserving wireless microphone access to spectrum, even as manufacturers innovate to use the remaining airwaves more efficiently.

The WMSA's work is already gaining traction. With more than 200 members, it has begun drawing attention in Washington at a critical moment, as the United States prepares to co-host the 2026 FIFA World Cup and later welcome the 2028 Los Angeles Olympics, two enormous global events that will rely on hundreds of wireless microphones for live performance, broadcast, and ceremony production.

Its outreach spans the White House, National Telecommunications and Information Administration (NTIA), FCC, and Congress, reinforcing how essential wireless microphones are to live performance, broadcast, cultural storytelling, religious services, and civic engagement. As Sinclair put it, “We can innovate all we want, but without spectrum, we’re just building better paperweights.”

Sinclair also floated an idea that goes beyond better microphones and smarter antennas—fixing the imbalance at its source. Many parts of the radio spectrum are still occupied by legacy government systems that haven’t been modernized in decades. Instead of pleading for scraps of spectrum, the professional audio industry could partner with agencies to modernize their outdated communications equipment, offering better technology in exchange for access to cleaner airwaves.

He suggested manufacturers and private sector innovators could help by providing modern replacements for that aging infrastructure, freeing up underused bands for shared, coordinated access. “There are military and public safety systems out there still running gear designed in the 1970s,” Sinclair said. “They’re holding huge chunks of spectrum hostage because no one’s upgraded them.”

As Moorut noted, during the 600 MHz auction, broadcasters—one of the largest groups of professional wireless microphone users—received roughly half of the auction’s proceeds, around $10 billion. That scale of compensation underscores how valuable this spectrum is to the wider media ecosystem, why the wireless production community must be included when national spectrum decisions are made, and how meaningful funding already exists to support the kind of modernization Sinclair is calling for.

Engineering Creativity Under Constraint
Despite the challenges, the show always goes on. Engineers have adapted by developing meticulous coordination strategies that resemble air traffic control. Frequencies are planned weeks in advance, with backup sets pre-programmed and tested. Large events can involve dozens of engineers managing hundreds of transmitters and receivers, all synchronized to avoid collisions.

Sinclair recalled a recent broadcast where every spare frequency was spoken for. “We had to label each transmitter like it was a boarding pass," he said. "One mistake and someone’s mic would vanish mid-sentence.” Some productions have even started reverting to wired microphones for reliability, not as a nostalgic choice but as a practical one.

It’s a strange twist: The technology that once symbolized freedom now represents a kind of scarcity. Yet within those constraints, creativity thrives. It forces precision, collaboration, and a renewed respect for the craft of live sound.

If history is any guide, the demand for wireless bandwidth will only grow. Each new generation of mobile networks (5G, 6G, and beyond) will hunger for more spectrum. Without deliberate protection for professional audio, the remaining white spaces could vanish entirely.

Spectrum is a shared public resource. Every wireless signal, from a singer’s microphone to a teenager’s smartphone, travels through the same air. What’s at stake isn’t just bandwidth, it’s the ability to express and connect through live sound.

The professional audio community has always been inventive, finding ways to make art work under constraint. But the next chapter will depend on collaboration—engineers pushing technology forward, manufacturers sharing innovation, and policymakers ensuring that culture has a place in the spectrum. The future of wireless audio won’t be about finding empty space. It will be about learning how to share it wisely.

OSLO, Norway—Appear, a global provider of live production technology, today announced that its X Platform has been officially verified by YouTube for Secure Reliable Transport (SRT) live streaming. This verification enables broadcasters, rights holders, and production teams to deliver high-quality live content to YouTube using Appear’s X5, X10, and X20 hardware platforms, providing a seamless, resilient and low-latency high-quality streaming workflow for news, sports, and live event coverage, the company said..

“Becoming a YouTube-verified encoder partner is a significant step forward for us and our customers,” said Thomas Bostrøm Jørgensen, CEO at Appear. “It reinforces our position in professional-grade IP contribution and gives our users a powerful new route to reach global audiences across one of the most important platforms in digital media.”

Appear says its partnership with YouTube was prompted when a major European broadcast platform approached YouTube to request support for Appear’s encoders in their production pipeline. That initiated a collaboration between Appear and YouTube, culminating in full verification for Appear’s hardware-based AVC/HEVC encoding and SRT streaming, further expanding Appear’s reach across a broader ecosystem of FAST, OTT and hybrid broadcasters.

“YouTube collaborates with technology partners to ensure their products meet our highest standards for reliability and performance when streaming to YouTube Live” says Callum Hewett, Live Solutions Consultant, YouTube. “We’re pleased to verify Appear’s X Platform for SRT delivery which we hope will streamline content delivery for all of their partners. It’s been great working with Appear on this and I look forward to seeing high-quality, resilient live production workflows delivered to YouTube via the Appear platforms.”

The broadcast industry has seen major transformations, but what we’re facing now is a deeper shift. It’s not just transport or tools. It’s a rethinking of how we build, scale, and operate live production infrastructure.

You’ve probably heard “infrastructure as code” a lot lately. For some, it’s the next step in automating and scaling live production. For others, it sounds like handing your OB van to a DevOps engineer with a YAML file.

I get the skepticism. But if you look at where the pain points in live production are today, you’ll see this isn’t just another tech trend. It’s a strategic necessity.

Why This Feels Risky (and why it’s necessary)
For decades, broadcast engineering has been a hardware-first, hands-on craft. SDI routers, frame syncs, multiviewers, and patch panels were built with precision and meant to run 24/7. Rebuilding a live environment on demand in the cloud? That’s a radical shift.

This works well for customers in sports, OTT, and fast-channel environments. They want modular workflows, not one-size-fits-all systems. But flexibility brings complexity.

It’s relatively easy to code infrastructure to spin up servers, storage, and connections. But configuring tech from 10 different vendors? That’s the real challenge. You need a unified, software-based control system.

The Real Bottleneck: Control
The industry’s made progress solving video transport. SMPTE ST 2110 helped us move beyond SDI into scalable IP production. But in focusing so hard on transport, we overlooked something else: control.

As we added more vendors, cloud services, and hybrid workflows, that gap became more obvious. It’s not just the complexity. It’s the manual overhead of stitching together multiple systems in real time. That doesn’t scale.

Customers don’t want one big system from one vendor. They want to curate their own stack. At Ross, we now support over 200 control protocols across our products. No one would design a system that way, but here we are.

Event-based, ephemeral infrastructure makes sense. But with a dozen vendors, each with different APIs and quirks, spinning it up isn’t trivial.

What is Infrastructure as Code?
It means managing infrastructure with software logic instead of manual steps.

Think:

• Configuration as version-controlled text files
• Automated deployments of full production environments
• Predefined templates that launch workflows in minutes

Engineers don’t need to become Python programmers. But they’ll spend less time fixing protocol mismatches and more time producing content.

In software, Infrastructure as Code defines entire environments, networks, services, storage, application workflows, via configuration files. Tools like Terraform and Ansible aren’t just for DevOps anymore. Broadcast engineers need them to deliver scalable, on-demand infrastructure.

At AWS, this approach runs some of the most advanced live workflows in the industry. It’s not just about cost, it’s about agility.

Not Just Hype: A Culture Shift
Let’s be honest: not everyone’s ready for this.

Broadcast engineers aren’t usually trained in cloud orchestration or declarative configs. That’s not a criticism. It reflects how the industry grew up. Our workflows were built to be robust and hands-on.

Going in as a traditional engineer will be tough. If we don’t invest in training — or use automation to bridge the gap — adoption will stall. But tools exist to help. That’s part of what SMPTE ST 2138 (Catena) is about.

ST 2138 provides a vendor-agnostic, software-based control layer across on-prem, private cloud, and public cloud, without rewriting APIs each time.

The Payoff: Real Agility
The goal isn’t to turn live production into a science experiment. It’s to reduce friction—especially when you need to launch fast, reconfigure often, and scale on demand.

Software-defined infrastructure lets teams work faster and more consistently. It’s the only path forward if you need to do more with less. You can’t afford brittle, inflexible systems.

With a software-defined control layer you can:

• Launch events in hours, not days
• Automate failover, resource allocation, and monitoring
• Test environments in isolation
• Run infrastructure only when needed
• That’s not just smart engineering. It’s good business.

Final Thoughts: Change is Hard; Standing Still is Harder
ST 2138 provides a unified control standard across vendors, platforms, and environments. It simplifies control and enables multi-vendor automation.

This shift challenges legacy thinking, skills, and comfort zones. But it’s already happening. If you’re skeptical, that’s healthy. But the transition won’t wait.

To future-proof operations and protect quality and creativity, we must stop start seeing infrastructure as code: reusable, testable, scalable, and under your control.

That’s not the end of engineering. It’s the evolution of it.

Infrastructure as code won’t replace the art of live production. It just changes how we manage the canvas.

The draft of ST 2138 (Catena) is now open for consultation. If you’ve ever wrestled with multi-vendor control or hybrid workflows, we need your help.
