Green can be computed from Brightness (Luminance), Red, and Blue information.
Y, R, and B are not stored for every pixel 4:2:2 sampling: Y on every pixel, R+B on every other 4:2:0 sampling: Y on every pixel, each of R and B on every fourth pixel 4:1:1 sampling: Y on every pixel, R+B on every fourth pixel
