Apparatus and method for controlling television receiver
First Claim
1. A method for controlling a television receiver comprising the steps of:
- (a) checking whether an input signal is a rotary encoder signal outputted from a rotary encoder;
(b) when said input signal is a rotary encoder signal, checking whether said input signal is an increase signal or a decrease signal and operating the television in accordance with said rotary encoder signal; and
(c) when said input signal is not a rotary encoder signal, checking whether said input signal is a key signal, and, when said input signal is a key signal, operating the television in accordance with the corresponding key signal;
wherein step (b) further includes the sub steps of;
when a first input signal has been applied from said rotary encoder, reading a second input signal applied from said rotary encoder to a second interrupt terminal and when said second input signal is a high signal, setting an increase flag, and when said second input signal is a low signal, checking whether a decrease flag has been set and,when said decrease flag has been set, resetting said decrease flag and recognizing said second input signal as a decrease direction signal;
when said decrease flag has not been set, recognizing said second input signal as an erroneous signal;
and wherein, when said second input signal has been applied from said rotary encoder, reading said first input signal applied from said rotary encoder to a first interrupt terminal and checking whether said first input signal is a high signal or a low signal; and
when said first input signal is a high signal, setting said decrease flag; and
when said first input signal is a low signal, checking whether said increase flag has been set and,when said increase flag has been set, recognizing said first input signal as an increase directional signal, andwhen said increase flag has not been set, recognizing said first input signal as an erroneous signal.

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.
