ABSTRACT:
Apparatus and method for controlling, using a rotary encoder, a television receiver. The remote control unit comprises a keyboard, a rotary encoder controlling the volume and the output level of a selected OSD signal as well as selecting a channel and a position of OSD signal, a remote control microprocessor and a remote signal transmitter. The television receiver unit comprises a remote signal receiver, a microprocessor and a signal processing circuit. The remote control microprocessor checks whether an input signal is a rotary encoder signal and whether the input signal is an increase signal, and operates in accordance with the rotary encoder signal or the corresponding key signal. The microprocessor of the television receiver unit checks whether a rotary encoder signal has been inputted, operates the inputted rotary encoder signal as a channel increase or decrease signal or as a control signal corresponding to a selected on-screen display signal, displays an OSD signal indicative of the output level of the selected OSD signal, and displays the OSD signal on the screen.
