The color space matrix consists of 3 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
provides a set of default input and output values for 100%
color bars. The component values given will be after the pre-
processing block and prior to the sync and pedestal insertion.
The blank, pedestal, and sync values are given as a reference.
Table 4 gives the default coefficients values for the CSM.
