Traditional broadcasters struggle to widely support even 4K, but new layered codecs like VVC offer some hope. They will be particularly helpful for streamers and for hybrid delivery (a base layer via DTT or DTH or cable + OTT for the enhancement layers).
@ciation The NHK "Super Hi-Vision" project, the implementation of which can be observed at the "NHK Open House" originally envisaged achieving 8K120 Hz. During the research there occurred optimization separately for stationary and mobile TV receivers with a standard channel width of 6 MHz. VVC encoding provides a significant increase in video signal compression compared to HEVC. In analog TV, each pixel contains a large number of color levels. If in a digital video stream placing multiple bits in one bit as in an SSD, further increases can be achieved compression ratio for DTT, which at 8K120 Hz will increase 8 times compared to 4K60Hz. There are China CCTV-8K based on 5G and AVS3 codec and DVB 8K works.
8K is successfully advancing in various directions, with the exception of DTT (Digital terrestrial television).
