Digital output signal ?

[shacard]

Hello,

Do we know the kind of digital video signal Blu-ray players can output ?
- RGB 4:4:4
- YCbCr 4:4:4/YCbCr 4:2:2
- the two of them ?

Some displays or scalers, with only DVI/HDCP input, may only support RGB signal...

From what I heard, RGB 4:4:4 will be supported.

Well, the answer seems to be in the HDMI 1.2 specifications :

"6.2.3 Pixel Encoding Requirements

Only pixel encodings of RGB 4:4:4, YCBCR 4:2:2, and YCBCR 4:4:4 (as specified in Section 6.5)
may be used on HDMI.
All HDMI Sources and Sinks shall be capable of supporting RGB 4:4:4 pixel encoding.
All HDMI Sources shall support either YCBCR 4:2:2 or YCBCR 4:4:4 pixel encoding whenever that
device is capable of transmitting a color-difference color space across any other component
analog or digital video interface except where that device would be required to convert RGB video
to YCBCR in order to meet this requirement.
All HDMI Sinks shall be capable of supporting both YCBCR 4:4:4 and YCBCR 4:2:2 pixel encoding
when that device is capable of supporting a color-difference color space from any other
component analog or digital video input.
If an HDMI Sink supports either YCBCR 4:2:2 or YCBCR 4:4:4 then both shall be supported.
An HDMI Source may determine the pixel-encodings that are supported by the Sink through the
use of the E-EDID. If the Sink indicates that it supports YCBCR-formatted video data and if the
Source can deliver YCBCR data, then it can enable the transfer of this data across the li"nk."
