Product data
7.1.6 Primary video channel
7.1.7 Secondary video channel
PNX8510/11 supports color space conversion only in the primary RGB Standard
definition data path. The fixed coefficients of this color space matrix are as follows:
R = Y + 1.371 x Cr
G = Y - (0.336 x Cb + 0.698 x Cr)
B = Y + 1.732 x Cb
The secondary display consists of the Y and UV processing data path of a video
encoder only. The synchronization information will be extracted from the incoming D1
data stream. The structure of the secondary display pipe is shown in
