ABSTRACT:
An encoder has a function of converting received digital RGB signals into analog television signals and a function of displaying on-screen displays. An internal chrominance signal generating section is driven and controlled by subsidiary display data supplied from outside via a subsidiary display data input terminal to output digital subsidiary display chrominance signals. A multiplexer selects and alternatively outputs either received main display signals or subsidiary display chrominance signals from the internal signal generating section. Switching of the multiplexer is controlled by a switching signal that is supplied from outside via a terminal.
