IP’s suitability for live broadcasting is no longer debatable. It’s been proven in a variety of real-world global deployments over the past several years. Even so, there’s lingering skepticism around IP and a surprising lack of understanding.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s. In the last article we looked at the incredibly complex relationship between lines and frames for NTSC systems used in the USA. In this article we look at the systems used in the UK and Europe.
AlphaDogs is one of the west coast’s premiere post houses, but even they find the prospect of creating UHD projects challenging.
Interest in TV SFNs is growing because ATSC 3.0 is designed to leverage SFNs for maximum bandwidth, with Pearl and Sinclair scouting the trail to a new way of broadcasting. SFNs aren’t new. Springfield MO Fox affiliate KRBK has been operating a multi-transmitter ATSC 1.0 SFN for several years. How is 3.0 going to be different?

It is not just broadcasters and pay TV operators that have struggled to cope with the accelerating momentum behind OTT, because it has been just as challenging for their technology providers.
The race to ever higher pixel counts never seems to end. One result is that consumers now believe that the path to higher quality images is through more pixels. Yet, other technologies like HDR, WCG and HFR can enhance every TV pixel by adding clarity, depth, and realism without requiring more bandwidth or expensive new production and broadcast workflows. The path forward depends choices made by television set makers as well as broadcasters.
