l CCIR 601
Y = ^{77R + 150G + 29B}

Range: 16 ~ 235
Cb = ^{− 44R − 87G + 131B} + 128
256
Range: 16 ~ 240
Cr = ^{131R − 110G − 21B} + 128

Range: 16 ~ 240
l Reverse CCIR 601
R = Y + 1.336 (Cr − 128 )− 0.002(Cb − 128 )
G = Y − 0.700(Cr − 128)− 0.334(Cb − 128)
B = Y − 0.006 (Cr − 128 )+ 1.732(Cb − 128)
