Pedestal not present:
0 = 7.5 IRE pedestal is present on the analog video input signal (default)
1 = Pedestal is not present on the analog video input signal
VBI raw:
0 = Disable (default)
1 = Enable
During the duration of the vertical blanking as defined by VBLK start and stop registers 22h through 25h, the chroma samples are
replaced by luma samples. This feature may be used to support VBI processing performed by an external device during the vertical
blanking interval. To use this bit, the output format must be the 10-bit ITU-R BT.656 mode.
Luminance signal delay [3:0]:
Luminance signal delays respect to chroma signal in 1
× pixel clock increments.
0111 = Reserved
0110 = 5 pixel clocks delay
0001 = 1 pixel clock delay
0000 = 0 pixel clock delay (default)
1111 =
–1 pixel clock delay
1000 =
–8 pixel clock delay
