Abstract
A multiplexed video signal interface in accordance with the present invention provides a multiplexed component video signal in which, in addition to the component video signals with OSD data and user-controllable contrast and video gain, includes control signal components for image brightness and CRT bias along with the ability to individually control such control signal components. This advantageously minimizes the complexity of the necessary signal interfaces and allows for greater integration of circuit functions, thereby significantly reducing circuit complexity, size and costs.
