[QUOTE="hexah, post: 1156908, member: 333852"] I was wondering when someone would try to make a dtt UHD mux. The 4k frame is four 1080 frames, so how will they squeeze the data into a dynamic 4-7 Mbps stream? h.266 is the latest and greatest but no real development or improvement yet. The patent pool seems to be a problem, again. h.265 is supposed to be the main choice but patent pool problems have meant there is not enough development and not enough effort on libre open alternatives. h.264 has had a huge amount of development because "h.262" MPEG was awful. There is a good libre offering x264. The work has been on encoding efficiency, and on processing the image before presenting it to the encoder. So perhaps it can be made to work with h.264 at level 5.1 with a lot of preprocessing the input giving an output which is soft and similar to the look of 0.6 to 1.0 Mbps h.264 broadcasts found on dtt in some countries. Add marketing crap and rake in the money?!? [/QUOTE]
