RGB Inputs

To avoid the black level of the inserted signal

differing from the black level of the normal video

signal, the external RGB are clamped to the black

level of the luminance signal. Therefore, an AC

coupling is required for the RGB inputs.

The RGB inputs are controlled by a 12dB range

contrast control stage.
