ABSTRACT:
A multi-channel video signal processing circuit with a bias control and respective video channel gain controls. The bias signal, which corresponds to a nominal video signal brightness level, is shared among the video channels which, in accordance with respective video gain control signals, process incoming component video signals to provide corresponding outgoing component video signals such that each one of the outgoing component video signals has a nominal outgoing video signal brightness level related to the bias signal and a corresponding one of the gain control signals.
