RGB / YUV
Setup Select
This bits specifies the blanking pedestal on the analog RGB and YUV outputs during active
video. Typically, this bit should be a “1” during (M) NTSC and (M, N) PAL operation. Otherwise,
it should be a “0”. This bit does not affect the analog composite or Y/C outputs.
0 = 0 IRE
1 = 7.5 IRE
