Automatic color killer:

00 = Automatic mode (default)

01 = Reserved

10 = Color killer enabled, the UV terminals are forced to a zero color state. 11 = Color killer disabled

Color killer threshold [4:0]:

1 1111 = 31 (maximum)

1 0000 = 16 (default)

0 0000 = 0 (minimum)

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 = Disabled (default)

1 = Enabled

During the duration of the vertical blanking as defined by the VBLK start and stop line registers at subaddresses 22h through 25h (see Sections 2.11.22 and 2.11.23), the chroma samples are replaced by luma samples. This feature can be used to support VBI processing performed by an external device during the vertical blanking interval. In order to use this bit, the output format must be 10-bit ITU-R BT.656 mode.

Luminance signal delay [3:0]: Luminance signal delays with respect to the chroma signal in 1pixel clock increments.

0111 = Reserved

0110 = 6-pixel delay

0001 = 1-pixel delay

0000 = 0 delay (default)

1111 = −1-pixel delay

1000 = −8-pixel delay
