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.
