Wait a minute! I thought xvYCC WAS "deep color" and currently comes in three flavors: 8-bit (24-bit RGB), 12-bit (36-bit RGB) and 16-bit (48-bit RGB), with the last one offering 281,474,976,710,656 possible colors. Also, it was my understanding that the first "deep color" device was not a BluRay player but the Sony PlayStation 3. Am I wrong??

It seems xvYCC as well Deep Color and Dolby Tru HD features of HDMI 1.3 may only be implemented in Blu Ray and only be displayed on devices that are capable. For the rest of the media distribution infrstratute it is mission impossible. Even in Schubin's Super High Quality digital theater system it is not happening...

I?m struggling with that chicken/egg problem for Internet delivered content. It might be possible to write new rules for a new channel and new devices, but if those files land on legacy devices or plug into legacy displays resulting in people have green faces ? I don?t see a bridge to transition from a 709 to xvYCC world of content and devices. Well, if all render devices recognized xvYCC content and displays, and could convert to 709 output if xvYCC isn?t supported, then it would work ? but requiring that of all devices (which eliminates most existing devices) isn?t likely.

This format is in use for display of Mark Schubin events. Have these events utilize the xvYCC color space or HDTV color space?

John ----- Original Message ----- From: "Mike Tsinberg" To: Sent: Monday, August 31, 2009 2:04 PM Subject: [opendtv] Re: 1080P Question In that case I see a motion problem. If original film is captured with 24 frames/sec and converted to 1080p/60 frames/sec for display - the motion will have 2/3 pull down type of motion jitter. On the other hand 24 frames/sec film displayed at 72 Hz or 96 Hz will not have such problems. So what is the point to display 1080p/60 in the movie theater?
