[opendtv] Re: 1080P Question

But, how bad does it look when content is encoded xvYCC and the display (or 
something else in the signal chain) clips negative RGB coefficients to Rec 709 
gamut?

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.

When source and display are both at xvYCC the results are sepctacular!

We transmit based on Rec. 709 (HD color space).  Digital-cinema theaters may 
transcode to whatever works best for them.

So practical use of 1080p/60 for transmission is questionable at best. This 
format is in use for display of Mark Schubin events. Have these events utilize 
the xvYCC color space or HDTV color space?

1080p60 in a theater setting is useful for live Pay Per View events. John -----

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? Best Regards, Mike Tsinberg Key Digital Systems Cell:
