RGB_OUT, IO Map, Address 0x02, [1]
RGB_OUT is used in conjunction with the INP_COLOR_SPACE[3:0] and
select the applied CSC (refer to Table 45). It sets up the output color space and the correct digital
blank level and offsets on the RGB or YPrPb outputs.

ALT_GAMMA , IO Map, Address 0x02, [3]
ALT_GAMMA is used in conjunction with the INP_COLOR_SPACE[3:0] and
select the applied CSC (refer to
formats, irrespective of the input formats. If this bit is set, it gives an output that is in a different
format from the input.

Description
Output color space is YUV
Output color space is RGB
Table 45). The output YUV can be in the YUV601 or YUV709
Description
YUV601 input, RGB_OUT = 0 – YUV601 output
YUV709 input, RGB_OUT = 0 – YUV709 output
YUV601 input, RGB_OUT = 0 – YUV709 output
YUV709 input, RGB_OUT = 0 – YUV601 output
