The required input signals are: luminance and negative colour difference −(R−Y) and −(B−Y), and a 3-level sandcastle pulse for control purposes. Linear RGB signals can be inserted from an external source. RGB output signals are available for driving the video output stages. This circuit provides automatic cut-off control of the picture tube.
