but i just wondering:
Not even the Samsung UE55F9000 seems to have the wider rec2020 gamut..whats that all about?..cheap specs for the first versions of 4K tvs..rec2020 is standard for UHDTVs right?
i also have seen a test from the new Xperia Z Ultra tablet that has Triluminos color.
from those results its only producing rec709 colors.
(maybe the problem there was the lack of Triluminos content i dont know)
what do you think?
is there a diffrence between Triluminos content such as the new Mastered in 4K discs vs regular blu rays
None of the current 4K TVs support Rec.2020 to my knowledge. I assume that this will change in future versions. We saw a very similar pattern with the first Full HD TVs. Many unanswered questions back then. Some of the first Full HD TVs didn't even support Full HD processing throughout the entire picture processing chain, so Full HD would be downscaled, processed, and then upscaled again. The first 4K TVs only seems to embrace the lowest requirements for 4K. Sony takes it a bit further with xcColor support, but it's still far from Rec.2020.
There is some chatter in the industry about HDMI 2.0. Some lobbying is going on, and some seem to suggest that certain interest groups (traditional TV channel providers) lobby to have the Rec.2020 color gamut excluded from HDMI 2.0, simply because they could never carry that over their limited TV pipes. That would be bad. If that happens it will probably mean that we will be stuck on Rec.709 for a few more years, despite cable standard alternatives to HDMI. TV makers don't seem very keen on adopting Thunderbolt and DisplayPort.
We also had a quick talk in the comment section so I just thought I would re-post what I wrote about xvColor and "post processing".
It is not a post process per se. Only if you enable xcColor on a non-xcColor encoded movie. With for example the Mastered in 4K Blu-ray movies, xcColor is encoded into the video, based on studio masters of movies in DCI color space.
xvColor uses the same color primaries (and secondary colors points), and the same 6500 K white point. In other words you can basically use the same BT.709 calibration.
The extended colors in xvColor lies outside the grey scale range (of video levels), so if a xcColor signal (such as on the Mastered in 4K Blu-rays) is sent to a non-xcColor supported panel, it just throws the extra information away. These Triluminos TVs can use the extra information.

USB discs or downloaded?
damn this tv is nice
price is not
I think we will learn more about next-gen Blu-ray and HDMI 2.0 either at IFA 2013 this September or at IBC 2013 a bit later in September. Right now Sony only has a hard drive based solution with the FMP-X1 4K player. Sony's PlayStation 4 will also have access to the 4K movie service, but it will probably still be via download.
Hopefully price is coming down soon
