There are several standards regulating the YUV colorspace:

Y' = 0.299*R' + 0.587*G' + 0.114*B'
U' = -0.147*R' - 0.289*G' + 0.436*B' = 0.493*(B' - Y')
V' = 0.615*R' - 0.515*G' - 0.100*B' = 0.877*(R' - Y')
R' = Y' + 0.000*U' + 1.140*V'

Cb = -0.169*R' - 0.331*G' + 0.500*B' = 0.564(B - Y')
Cr = 0.500*R' - 0.419*G' - 0.081*B' = 0.713(R - Y')
R' = Y' + 0.000*U' + 1.403*V'
