Forward-looking content aware encoding for next generation UHD HDR WCG HFR

摘要

This paper shows how the future challenges ofvideo compression can be met by leveraging both expertisein optimized compression and latest advances in artificialintelligence, thus spending exactly the right amount of bitson each piece of video information. As we envision a worldof life-like TV, enhanced in all possible degrees of freedom,immersive 8K HDR WCG HFR is just knocking at our door.Although technology is improving at a constant pace,processing and transmitting such an amazing amount ofinformation remains an incredible challenge. The BBCtransmitted a UHD HDR live feed of the FIFA 2018 WorldCup at 36 Mbps. The ATEME TITAN Live encoder does italready at 22Mbps and lower. Even though the future ITU-TISO/IEC VVC is promising a 50% coding efficiency gaincompared to HEVC, compression will not be enough, thusleading to strategies like UHD forum Phase B guidelinesrecommended content aware encoding [1].
