A. MPEG strictly specifies the YCbCr color space, not YUV or YIQ or YPbPr or YDrDb or any other color difference variations. Regardless of any bitstream parameters, MPEG-1 and MPEG-2 Video Main Profile specify 4:2:0 chroma ratio, where the color difference channels (Cb, Cr) have half the resolution or sample grid density in both the horizontal and vertical direction with respect to luminance. MPEG-2 High Profile includes an option for 4:2:2 and 4:4:4 coding. Applications for this are likely to be broadcasting and contribution equipment.
