Conversion Operation
RGB data is converted to YUV by the following matrix expression :
Y = a11*R + a12*G + a13*B + b1
Cb= a21*R + a22*G + a23*B + b2
Cr= a31*R + a32*G + a33*B + b3
aij 10bit signed real ( lower 8bit is fraction )
bi 8bit unsigned integer
Each coefficients can be defined by following registers.
Cb and Cr components are reduced half after this operation to form the 4:2:2 format.
