The color space matrix consists of 10 multipliers with inde-
pendently adjustable coefficients, and a resolution of
0.00049 (1/2048). The amount of gain varies among coeffi-
cients, Table 1 summarizes the gain for each coefficient.

To aid in the programming of the color space matrix Table 2
and Table 3 provide a set of default input and output values
for 100% color bars. The component values given will be
after the preprocessing block and prior to the sync and ped-
estal insertion. The blank, pedestal, and sync values are
given as a reference. Table 4 and Table 5 give the default
coefficients values for the CSM in all modes and standard
video formats.
