Thanks Craig,
Yes if more 1080p content will come out with HDR the HDR will definitely be
more mainstream. In the case perhaps existing infrastructure: Cable and
Satellite STB's, Apple TV's can deliver 1080p HDR with a firmware upgrade.
Is it possible to use the same HDR metadata for 1080p or 4K versions of the
same content?
Best Regards,
Mike Tsinberg

Thanks Mark. This does a good job of describing the many significant ambient
light issues we are facing as we move to HDR.
My very un-scientific analysis, based on looking at TVs last week at Best Buy,
is that the use of OLED is likely to bring at least some of the benefits of HDR
to the masses across a variety of devices.
One other comment related to Mike's question about 1080P with HDR.
Much will depend on how affected industries decide to move forward with HDR and
improved masters. Obviously Hollywood is 4K with HDR and WCG now, although the
debate about film versus 4/8K electronic acquisition still continues. In the
end, Hollywood will deliver 4K to theaters, and 4K versions on Blu Ray and for
streaming. But I expect 1080P streaming will dominate.
For broadcasters the issue is related to the need to support both live and
pre-recorded programming. As you have implied, I believe the next step is to
move to 1080P (at all frame rates) with HDR and WCG. There's just not going to
be much need for higher delivered resolution with TVs that upsample to 4K. The
viewer will see more improvement from any available bits being used to improve
compression than to deliver 4K samples.
Regards
Craig

What's the effect when projecting on cinema-size screens? Seems like the
darkened venue is a plus, but the huge screen a minus? Almost like it would
require lasers.
