THATCHAM, U.K.—Test and measurement provider Phabrix, a Leader Company, has announced that its distributor, Logic Media Solutions, has sold multiple Phabrix Qx rasterizers, Leader LV5600 waveform monitors and LV7600 rasterizers to TVN Live Production. 

Headquartered in Hanover, Germany, TVN is one of Europe’s leading providers of mobile television services, working on high-profile productions including soccer tournaments and music festivals for more than 35 years. The company is also in demand as a supplier and partner in the development and introduction of innovative technical solutions.

The adoption of Ultra-High Definition (HDR) and High Dynamic Range (HDR) production workflows provided the impetus for TVN’s latest investment in T&M and monitoring equipment, the companies said. 

“With the beginning of the era of UHD and HDR, it was an easy decision to choose Phabrix instruments for our technical positions, and Leader instruments for our operator positions” said TVN CEO Markus Osthaus, adding that the two brands’ products fulfilled the company’s requirements for “user-friendly and flexible measurement devices for professional broadcast use”.

Working closely with Christophe Bingemer, managing director of Phabrix/Leader reseller Logic Media Solutions, TVN decided upon an investment comprising Phabrix Qx rasterizers, Leader LV5600 waveform monitors and LV7600 rasterizers. 

The Qx rasterizer brings together all the advanced tools required for transitioning to the next generation of video formats. Designed for HD/3G/6G/12-SDI and IP ST 2110/2022-7/2022-6 environments, as well as 4K/UHD production and advanced HDR analysis, the instrument set includes tools for rapid fault diagnosis, compliance monitoring and product development. 

Also supporting both new and legacy workflows, the Leader LV5600 is a ‘True Hybrid’ waveform monitor compatible with 4K/HD/SD-SDI signals and UHD/HD/SD IP signals, the company said. 

The LV7600 rasterizer offers the same capabilities as the flagship LV5600 but in a low-profile 19 inch 1U form-factor for easy rack or desk mounting. Engineering-related features include test pattern generation, eye pattern display, closed-caption monitoring, CIE chroma chart, HDR measurement, focus assist, customizable screen layout, tally interface and 4K/UHD operation as well as 10G/25G IP input and 12G-SDI interfaces.

Osthaus said that the new Phabrix and Leader equipment has already been deployed during its commitments to multiple tournaments: “TVN applies Phabrix/Leader measurement equipment at all Bundesliga matches, as well as UEFA tournaments such as Champions League, Europa League and Conference League – thus always providing the best picture quality and signal quality for our customers.”

As to the future, further investments in Leader group products are evidently a possibility. “When we plan and set up new studios or OB vans, the Phabrix/Leader products have become part of our standard equipment,” noted Osthaus, adding that the brands have “always been at the cutting edge of technology, and usually ahead of the competition in terms of innovation.”

“It is always gratifying to hear that a company with such a prestigious track-record as TVN Live Production has put its trust in Phabrix and Leader T&M and monitoring equipment for its work on hugely important productions like Bundesliga and the UEFA Champions League,” Masayoshi Ishihara, managing director, Leader Europe said. “With expectations rising ever-higher in the era of UHD and HDR production, TVN can depend upon the versatility and robust performance of the Qx rasterizers and LV5600 monitors to ensure that its customers – and their viewers – experience the best possible quality every time.”

 Newbury, UK—Phabrix has released a V4.3 software update for its Qx and QxL hybrid IP/SDI rasterizers that adds a multitude of new supported formats including RGB SDI and ST 2110 IP standards support as well as a unique and comprehensive 2110 IP Generation Toolset.

Phabrix CEO Phillip Adams noted that “this new software is the first in an intense six-month release roadmap. With a new powerful ST 2110 IP generation toolset, and a huge quantity of new SDI and IP standards supported, the Qx Series offers our customers a future-proof technology investment to stay ahead of the rapidly changing IP environment.”

The Qx Series is available in two platforms, the Qx and QxL, both with a common look and feel, providing an accessible user interface and intuitive toolsets for full operational flexibility and easy migration from an SDI to an IP centric operation, the company reported. 

The flexible architecture of both the Qx and QxL offers in-field license upgrades for SDI-UHD/4K, HDR as well as engineering grade data view and ANC packet inspection tools.

A factory fitted hardware option provides RTE real time SDI eye and jitter analysis with the further option of a highly advanced SDI-STRESS toolset. 

The Series’ comprehensive feature set supports HD/3G/6G/12G-SDI, 10G/25G IP interfaces, and HD/UHD, IP SMPTE 2022-6, SMPTE 2110-10/20/30/31/40 with ST 2022-7 and AMWA NMOS.

ALEXANDRIA, Va. — Rapid acceptance of IP video is driving many changes to traditional test and measurement equipment. There will always be the need for familiar quality control devices like waveform monitors and vectorscopes, but studios and content creators today also need the ability to examine the data they generate — and that data is increasingly distributed at blindingly fast speeds.

Couple that with the LCD/LED and microprocessor revolutions, and a lot of today’s test gear looks nothing like what was used 20 or 30 years ago. As dedicated video distribution facilities (think SDI) are replaced by IP networks, test gear manufacturers are sprinting to keep up with the new measurement realities — often coming up with innovations in the size, capabilities and performance of the latest test and measurement products.

“The test requirements for SDI systems are relatively well known and documented,” said Ian Valentine, business director for the video product line for Beaverton, Ore.-based Tektronix. “However, as the industry transitions to IP-based technologies, a whole series of new measurements is required to understand what is happening on the network during the transmission of packets containing video, audio and metadata. This includes packet loss, packet jitter, RTP sequence errors, and packet timestamp delay factors to mention a few.”

IP VIDEO TRANSPORT STANDARD

The recently developed SMPTE 2110 standard for IP transmission of professional video, audio and data is a big reason why there is a need for IP test gear in a television environment.

“There are a whole series of measurements around the timing of video, audio and data against PTP [precision time protocol] to keep the network synchronized,” Valentine said. “Timing is particularly important when dealing with the SMPTE 2110 standard where the video, audio and data essence is all sent in separate streams. Being able to test the integrity of the separate data paths is essential to ensuring that transmission reliability is maintained.”

With 12G-SDI and the latest high-speed Ethernet networks, even the most mundane basics have to be reconsidered. Take, for example, the BNC connector.

“As the industry transitions to IP-based technologies, a whole series of new measurements is required.” —Ian Valentine, Tektronix

“The BNC connector that the industry has used for more than 50 years is a spring-loaded bayonet — and using the real-time eye capabilities of the Phabrix Qx, you can see that this technology is right on the limit simply by touching and waggling the BNC connector and cable,” said Prinyar Boon, product manager for U.K.-based Phabrix. “Around 10mV signal amplitude variation is typically observed per connection. Return loss requires serious consideration and the extremely high rise and fall times specified can result in significant eye degradation with small changes in geometry. The good news is that correctly designed interfaces are very robust and reliable, and will operate at all SDI rates from SD through to 12G.”

‘DEVIL IS IN THE DETAIL’

BNC connectors are just the tip of the iceberg.

“At a very high level, going from 3G-SDI to 12G-SDI is the same, only faster — but the devil is in the detail,” Boon said. “However, the bandwidth change from 3 GHz to 12 GHz, or more typically 1.5 GHz to 12 GHz, means that 12G-SDI is much harder to implement. Components, printed circuit board material, stack buildup and physical layout all have to be remodeled, reselected and re-optimized. Even the bond wiring within an IC [integrated circuit] now has a significant impact on performance, and the latest generation of ICs are looking to use flip-chip technology to overcome this.”

Once the signal leaves the broadcaster’s facility and heads toward the viewer, IP distribution networks outside the studio are different in many ways from those inside.

“The main idea is to take a holistic view to analyzing the end-to-end content delivery chain, looking at the whole picture to determine the ‘cause-and-effect’ of any issues rather than simply isolated parameters here or there,” said Ted Korte, chief operating officer for Melbourne, Fla.-based Qligent. “Each method of content distribution — from ATSC 3.0 broadcasts to OTT delivery — has its own vital metrics, but it’s important to evaluate everything ranging from low-level quality-of-service metrics [which are very signal-specific] to humanly-perceivable QoE metrics.”

One popular way of television distribution has long been the cable TV industry, which has adopted hybrid-fiber/coax technology to deliver both traditional cable TV channels and broadband service. The standard for interleaving cable TV and bidirectional data on the same network is called DOCSIS (data-over-cable service interface specification), which is now up to DOCSIS 3.1 Full-Duplex.

With cable networks supporting bandwidth from 0 Hz to 1.2 GHz, it is a tough job to test and validate their performance. Rohde & Schwarz is one company that has a test set that can be used to test and maintain performance on DOCSIS cable networks, going up to 1.8 GHz for downstream signals to the home.

WHAT’S IN THE FUTURE?

There is a lot going on with technology in the television industry, so what looks to be one of the trends for test and measurement gear in the next couple of years?

“From [our] perspective, ATSC 3.0 will gain momentum over that timeframe,” said Ralph Bachofen, vice president for sales and marketing at Princeton, N.J.-based Triveni Digital. “This, of course, will include HDR and other advanced technologies and protocols as part of the migration. This makes it critical using a flexible test and measurement solution that can adapt based on market changes and advanced applications.”

On the production side, it’s clear that 4K is the target standard for production and its associated test devices.

“We see a demand for UHD/4K 3G- and 12G-SDI based systems,” Boon said. “With the 2018 Winter Olympics, Royal Wedding and 2018 World Cup all being shot and now distributed live in UHD HDR, there is clear proof that the technology is viable. Simultaneously shooting live productions in both conventional standard dynamic range [ITU-R BT.709] and HDR [ITU-R BT.2100] with wide color gamut poses its own set of challenges. This is particularly true with a mix of SDR/709 and HDR/2100 sources, be they cameras, replay systems or graphics devices.”

Every part of the production chain will need to be monitored to maintain the pristine quality to which viewers have become accustomed.

“Successful production of HDR/WCG content requires the right tools and new measurement techniques,” Valentine said. “Camera setup, for example, is more crucial than in the past given the risk of creating issues (e.g., noise in dark areas) that can’t be fixed in post-production. New techniques are also required to monitor the various camera log formats and conversion to PQ (perceptual quantizer) or HLG (hybrid-log gamma). HDR/WCG content production is the future.”

This is just a quick look at the corner of the industry dedicated to test and measurement, but it demonstrates how new standards bring new methods to examine and maintain the quality of those standards.
