Migration towards ST 2110 and ST 2022-6 video networks for production and content delivery is picking up pace as the advantages of IP versus traditional SDI over coaxial cable carriage become more evident. The key drivers of IP include the introduction of more flexible and scalable business models based on virtualization and cloud technologies, along with the economies of scale and speed of technology development that stem from the use of commercial off-the-shelf (COTS) IT equipment.
As higher resolutions become the “norm” in television production and broadcasting, improvements in coaxial cables and associated connectors to enhance performance in the 12G operating range provides a more practical solution for 4K transport.
4K imagery has become the quality standard for many broadcast applications. A key requirement is that the transmission links be of sufficient bandwidth. Links using H.264 can be overwhelmed by the much higher bandwidth requirements of 4K video. HEVC is often the better solution. How does it work and what are some benefits?
Last year, more than 400 original series hit the small screen. With no signs of slowing; predictions suggest 2017 could beat records, with over 500 programmes launched. It’s now possible for companies to make video easily accessible online and with the widespread adoption of Video on Demand (VOD) the content floodgates have opened like never before.

Broadcasters have historically not had to endure regular large-scale technology transitions. Sure, the industry moved from B/W to color, analog to digital, and SD to HD. But the upcoming move from the familiar and comfortable SDI technology to an IP-centric facility has many technical managers apprehensive. It is time to be calm and carry on.
Japanese broadcasters are preparing for the 2020 Tokyo Olympic Games, including getting ready for 8K UHDTV. In 2018, public broadcaster NHK will roll out the needed ISDB-S3 standard. The multichannel R&S SLG signal generator from Rohde & Schwarz was used for the 8K satellite tests.
In this interview, we meet Sean Prickett – a “young gun” audio mixer that’s making a name for himself on some of TV’s most high-profile live and audition shows. Most recently, Sean was A1 for the live-broadcast finals of the CBS reality-TV dance competition “So You Think You Can Dance” (SYTYCD), which just wrapped its 14th season. Other impressive A1 credits include the 2017 U.S. Presidential Inaugural Balls, SYFY Channel’s “Live from Comic-Con,” and MTV’s “Wonderland” and “VMA Weekend,” and he’s already out working on the new season of “American Idol.”
At the start of 2013, BCE at RTL City was a hole in Luxembourg’s ground and in less than four years they were on air broadcasting 35 different channels across Europe and Singapore. Costas Colombus is BCE’s Special Projects Manager and gave The Broadcast Bridge a unique insight into how they made this mammoth installation work, including describing the issues and how they overcame them along the way.
In this second article in the series we look at the IP routers Costas and his team chose, and why.
