UG-180
RGB_OUT , IO, Address 0x02[1]
A control to select output color space and the correct digital blank level and offsets on the RGB or YPrPb outputs. It is used in
conjunction with the INP_COLOR_SPACE[3:0] and ALT_GAMMA bits to select the applied CSC.
Function
RGB_OUT Description
0 (default) YPbPr color space output
1 RGB color space output
ALT_GAMMA , IO, Address 0x02[3]
A control to set the colorspace of the input video. To be used in conjunction with ALT_GAMMA and RGB_OUT to configure the color
space converter. A value of 4'b1111 selects automatic setting of the input color space base on the primary mode and video standard
settings. Setting 1000 to Setting 1110 are undefined.
Function
ALT_GAMMA Description
0 (default) No conversion
1 YUV601 to YUV709 conversion applied if input is YUV601. YUV709 to YUV601 conversion applied if input is YUV709
