•

CSMFMT = 01 , YCBCR input source with YUV and

RGB outputs.

Matrix conﬁguration:

Ycomposite

= MCF1 * Yin

= MCF4 * CB

= MCF6 * CR

= MCF8 * (MCF1 * Yin + MCF2 * CB

+ MCF3 * CR)

= MCF9 * (MCF1 * Yin + MCF5 * CB)

= MCF10 * (MCF1 * Yin +

MCF7 * CR)

•

CSMFMT = 10 , RGB input source with YUV and

YPBPR outputs.

Matrix conﬁguration:

Ycomposite

= MCF1 * Gin + MCF2 * Bin +

MCF3 * Rin

= MCF4 * Bin + MCF5 * Ycomposite

= MCF6 * Rin + MCF7 * Ycomposite

= MCF8 * Ycomposite

= MCF9 * U

= MCF10 * V

•

CSMFMT = 11 , RGB input source with YUV and RGB

outputs.

Matrix conﬁguration:

Ycomposite

= MCF1 * Gin + MCF2 * Bin +

MCF3 * Rin

= MCF4 * Bin + MCF5 * Ycomposite

= MCF6 * Rin + MCF7 * Ycomposite

= MCF8 * Gin

= MCF9 * Bin

= MCF10 * Rin

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.
