You may find my questions totally noob, but i would like to make clear theory about color conversions.
i didnt found a sub-forum for general theory about displays or bluray players so i post it here. Moderators can always move it anywhere.
All the people in HTPC`s area talk about the new madVR - video renderer and the noticable improve of Picture Quality.
According to the developer there is no way to upsample the color on a pc without converting this to RGB first. Its impossible the card to output untouched YCbCr data,
so he suggests to set our htpc cards' pixel format to rgb and our display`s input source also to rgb.
With this project we skip one color conversion setting it up fullRGB 4:4:4 all the way. The only conversion that happens this way is the 4:2:0 to RGB.
But what happens with our standalone bluray players? Does anybody know if consumer electronics when uplsampling 4:2:0 to 4:2:2 or YCbCr 4:4:4 also convert the color first to rgb and then to YCbCr?
If we assume that we have a perfect bluray player like oppo93 and a display capable to handle both RGB/YCbCr which color format we would choose?
YCbCr 4:4:4 or RGB?
Where is the best place to do the color conversion?
4:2:0 to 4:4:4 in the player ---> 4:4:4 to RGB on the display (two color conversions)
or option 2:
4:2:0 to rgb in the player ---> no color conversion on the display (one color conversion)
