Automatic color killer

Color killer threshold [4:0]

Automatic color killer:

00 = Automatic mode (default)

01 = Reserved

10 = Color killer enabled, the C terminals are forced to a zero color state

11 = Color killer disabled

Color killer threshold [4:0]:

11111 = 31 (maximum)

10000 = 16 (default)

00000 = 0 (minimum)

present

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
