I missed seeing Joe on this trip
. Alas, I think there is zero chance the format will be anything but 4:2:0, 8-bit when it comes. Joe is right of course. We should make it 10 bit because that is the production resolution (if not higher). Correct conversion to 8 bit requires dither which makes compression harder. So 10 bit can actually take the same bandwidth as 8 bit! But folks don't understand that and will most likely go with 8 bits again. Higher color sampling will take more bandwidth and will also requires more CPU cycles/RAM/Power in the decoders. And studios may want to make sure the specs don't approach digital cinema. For these reasons I don't think we are going to get anything more than a resolution bump. Even there, I don't expect 4K to come anytime soon in volume. There will be many incompatible sampling type service (e.g. what Sony is doing by bundling a server with their 84 inch UltraHD set), but nothing representing mass market is on the roadmap yet.
