From my sources, it will support triple layer BD (100 GB) but that will probably be on a title by title basis (like dual layer now). 10 bit 4:2:0 for color resolution. BT 1886 for gamma AFAIK
, but we'll see.
Obviously none of this is set in stone, this is just what my inside source is saying, and he is rarely if ever wrong on this stuff. But he says they are still going back and forth and the delay has to do with everyone deciding on something and the BDA (CE companies) and studios are not seeing eye to eye.
Thanks a lot for sharing this insider info and for confirming the UHD res.
Have you noticed that in the CNET article linked above by imgEL http://www.cnet.com/news/4k-blu-ray-...reaming-media/
the Panasonic guy mentions BT2020, not P3, and says that the players will be able to detect if the displays handles such gamut and make use of it?
This is interesting on two points.
First BT2020 would make more sense than P3 if the res. is UHD and not 4K. I'd say that 4K/P3 makes sense, UHD/BT2020 also, but UHD/P3 makes little sense. Do they crop the P3 master or do they scale it to fit the smaller UHD res? Neither is ideal, so I'd prefer 4K/P3 personally, at least we could make use of the 1.89:1 4K panels on the 4K Sony PJs. I'd love to replace my 16/9 screen by a 19/10 one to make use of that and get smaller black bars. That would be a good compromise for me between 2.35 and 1.78.
Second it would mean that no consumer display available currently or in the near future can take advantage of the larger gamut, unless they have a delivery mechanism in place to adapt to P3 as well as rec709. Also rec709 and rec2020 share the same D65 white point so it would make it much easier to switch between the two, while P3 has a different white point which a slight calibration hassle.
It would be interesting to find out more about this if your source is reachable
EDIT: One last thing that would be interesting is if there is any support for 21/9, which is part of the HDMI 2.0 specs.
