What is better RGB or ycbcr444 or ycbcr422?
For monitors, always use full RGB (0-255). For TVs, use YCbCr 4:4:4 (preferably). From there, to YCbCr 4:2:2 and to YCbCr 4:2:0 the amount of chroma subsampling increases, while the bandwidth required decreases. With that, also the quality degrades, as more subpixel color values are discarded/approximated.
Why is YCbCr better than RGB?
YCbCr Video
The difference between YCbCr and RGB is that RGB represents colors as combinations of red, green and blue signals, while YCbCr represents colors as combinations of a brightness signal and two chroma signals. In YCbCr, Y is luma (brightness), Cb is blue minus luma (B-Y) and Cr is red minus luma (R-Y).
What does YCbCr stand for?
YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YCBCR or Y′CBCR, is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y′ is the luma component and CB and CR are the blue-difference and red-difference chroma components.
What is the difference between YUV and YCbCr?
YUV is an analog system. YCbCr is a digital system and widely used in video compression e.g. MPEG2. The range of RGB is 0.. 255 e.g. R value can be from 0 – 255.
