Industry consultant Ron Williams talks about what he learned at the recent Hollywood Post Alliance Tech Retreat, including the upcoming ATSC 3.0 terrestrial-broadcasting standard, cable shows being broadcast over the air, the Aereo online-terrestrial service, the new Google/YouTube codec, the importance of high dynamic range and wide color gamut for the future of UHD, the finalization of the SMPTE UHD specifications, the industry's adoption of audio and video over IP, the coming domination of China in the consumer AV market, answers to chat-room questions, and more.

Unfortunately the benefits of HDR (and all the wider gamuts) are radically reduced by the heavily compressed consumer delivery formats. Uncompressed Rec709 (the current consumer/broadcast color spec/gamut) is so different from the Rec709 we get from Blu-Ray, let alone cable or streaming, that most HT buffs would likely be blown away if they saw a demonstration.
I really hope the wider-gamuts/HDR discussions and proposals include a new consumer delivery format that will adequately support the color/visual improvements for which we're paying.
Scott, A key question:
Is the proposed ATSC 3.0 compatible with the current ATSC?
If not how does the industry expect to make the transition -- for both transmission and reception sides?
The NTSC to ATSC transition required two 6MHz channels per station, but in many markets there are not many spare channels and the FCC is trying to shift many frequencies away from broadcast to cell phones...
