ATSC 3.0 continues its march toward acceptance as the television transmission standard in the U.S., with many products boasting of compatibility. In addition to ATSC 3.0 getting nods of approval by both the FCC and industry groups, the television repack continues apace, and that is also driving development of new products.
GATESAIR will highlight its Maxiva VAXTE air-cooled transmitter, for Band III and low-band VHF, with support for power levels up to 38kW. The VAXTE is driven by the XTE software-defined exciter featuring real-time adaptive correction and ATSC 3.0 capability.

SATELLITE, MICROWAVEAND REMOTE
In the past 10 years, the growth of IP technology and cellular networks created a revolution in how signals are sent from a remote camera back to the studio. Where you once had dedicated lines (expensive), satellite feeds (expensive) and microwave links (expensive), now relatively cheap internet service or cellular wireless links can do the same with much more flexibility at a tiny fraction of the price.
We’re almost at the point where a well-equipped cell phone and a solid 4G wireless connection can do most of what it used to take a microwave truck to do. And it doesn’t require a license… or insurance.
AMT will feature the StreetNode portable LTE camera transmitter and SkyNode helicopter transmitter for its ENGenesis LTE microwave system.
BMS will discuss the MTxx24VHD unmanned COFDM microwave link that offers low-latency wireless HD video in a small, light footprint targeted at UAVs and other unmanned systems. The MTxx24VHD provides secure HD video transmission using AES encryption and H.264 compression.

MARSHALL ELECTRONICS and IMT will show their combined wireless video solution for live broadcasts and sporting events. The integrated bundles include one of IMT’s ultra-miniature wireless video systems (IMTDragonFly or MicroLite 2 HD COFDM wireless video transmitter), as well as a Marshall Mini-Broadcast POV camera such as the CV502.
MOSELEY will show its mobile and fixed microwave line, including the DTV Link- A STL systems. The DTV Link-A works in any microwave band from 1.5 GHz to 13 GHz and it can carry data loads as high as 155 Mbps.
VIDOVATION will demonstrate ABonAir’s AB512 radio system. Built on a bidirectional radio channel between transmitter and receiver, ABonAir’s wireless video links acknowledge the correct acceptance of each group of pixels with only a 7ms delay for applications in which latency of 2-6 frames or 30-90 ms is unacceptable.
COMREX will showcase LiveShot, which delivers live, two-way HD video and audio over a range of IP networks at latencies as low as less than 200mS.
DEJERO will feature CellSat, a system that works with the company’s EnGo mobile encoder to combine cellular networks with Intelsat satellite connectivity, increasing reliability and coverage. CellSat simplifies transmission using multiple connection paths so field crews can capture live news and events with confidence.
LIVEU will highlight its flagship LU600 portable transmission solution with the HEVC Pro card. Combined with the 4K HEVC Pro card, the LU600 allows broadcasters and content creators to benefit from high video performance and bandwidth efficiency in a small package.
TVU NETWORKS will introduce TVU Timelock, which enables remote events to be produced from a control room in a separate location. With the solution, TVU transmitters can synchronize together at a set latency, allowing mobile and wireless at-home/REMI prodocutions without being tethered. Also new is the TVU Transcriber, an AI-based audio-to-text transcribing service that uses voice recognition technology. The company will also introduce improvements to its existing line of IP video workflow solutions, with enhancements to its video acquisition, transmission, production, distribution and management technologies.
IP & STREAMING
AKAMAI will showcase its liveOrigin platform, which combines broadcast-quality ingestion, low-latency, a “self-healing” network and performance monitoring/reporting to support the same level of quality for live and linear video streaming that’s expected of traditional broadcast TV. Akamai is complementing its delivery capabilities with demonstrations of its Broadcast Operations Control Center (BOCC) and its Broadcast Operations Support System (BOSS), media analytics tools that are designed to provide operational insight and telemetry from origin to viewer, offering control of and visibility into video operations and performance.
ARTEL will feature its DigiLink line of IP distribution products, including the DL4360x modular 3RU 12-slot chassis that can support multiple channels of video and Ethernet traffic.
DVEO will highlight the T-Mux IP/IP multiport multiplexer/demultiplexer that is used to combine or uncombine any number of incoming MPEG-2/H.264 IP transport streams, SPTS or MPTS.
BARNFIND will introduce the BTF1-41 series, the company’s first signal transport product with 12GB capacity and built-in SDI to IP. The series will use the BarnStudio control system and offer the same third-party control as the existing BarnOne 3G system.

COBALT DIGITAL will debut the 9414DAEO/OE-12G multichannel fiber extension cards that can transport 12G-SDI video over optical cable. The 9414DAEO/OE-12G installs in an openGear frame that can hold up to 10 cards, providing 20 channels of 12G transport.
COMREX will debut EarShot, which provides telephone-based live studio program and IFB audio to field-based remote broadcasts. Up to 30 users can listen to program or IFB feeds by calling into EarShot with a mobile phone, and EarShot can handle up to four program feeds, or two IFB feeds.
MULTIDYNE will debut the latest version of its SilverBack signal transport system: Silverback-12G, which provides a full-bandwidth fiber-optic link between two cameras and a production truck or control room. The company will also showcase the VF-9000, which addresses the growing need for higher signal density, format flexibility and operational versatility in a fiber transport frame and is available in 18- and 36-channel versions.
CABLE, FIBER & CONNECTORS
Now that production and editing in 4K is common and virtually no more expensive than HD, cables, connectors, patch panels and terminal gear is increasingly built to support uncompressed 4K transmission. If you are putting new cable and infrastructure into a facility, it makes sense to future-proof it by going the 4K route (also known as “12G”). Expect to see lots of 12G fiber and cabling solutions at the 2018 NAB Show.
BELDEN will feature its new 4694R RG6 precision video coax designed for 4K indoor riser applications. Rated out to 12 GHz, 4694R meets SMPTE 2082-1 (12 Gbps) and SMPTE 2081-1 (6 Gbps), as well as HD-SDI.

The singlemode fiber-optic cable with polyurethane jacket can be used for temporary deployment directly on the ground in all terrains. They are available with LC, SC or ST connectors and in a variety of lengths. Camplex will also spotlight its HF-FCFF-CM-T SMPTE fiber tactical hybrid camera cables that meet SMPTE 304M and 311M standards. Terminated with Canare FCFA to FCMA connectors, the lightweight cables are designed with an abrasion-resistant polyurethane jacket targeted at temporary installation where quick retrieval and recurrent use is necessary.
GRASS VALLEY will show off its Viper family of fiber-optic connectivity product, including the Viper 1 that provides two-way video, audio, intercom and data transport.
