World Cup 2018 in UHD HDR on BBC iPlayer OTT service

If you live in the UK you can watch the World Cup live via the BBC iPlayer OTT service in 4K and HDR (HLG). This is very cool. You can read all about it here:

The only downside is that they have a very poor live HEVC encoder. From the BBC Blog:

"The distribution to iPlayer will be Main 10 Profile, Level 5.1 HEVC with HLG signalling. This is the same as we used for our Blue Planet II trials. For Blue Planet II we were able to use non real-time encoding. For our World Cup 2018 coverage we must use real-time encoding. The current state of the art for live HEVC encoding means we need to use increased bitrates and reduce the number of representations we can make available. For the World Cup we will be offering:

  • 3840x2160p50 36Mbit/s

  • 2560x1440p50 16Mbit/s

  • 1920x1080p50 10Mbit/s

  • 1280x720p50 7Mbit/s

They really need our Chestnut HEVC live encoder. We could reduce the bitrates by ½ to ⅔ with the same quality and generate all the HLS/DASH renditions in parallel.
