Abstract

본 발명은 자동 프로그램 제어장치에 관한 것으로, 종래에는 채널이 기억되어 있지 않을 경우 방송이 수신되지 않을 뿐만아니라 채널 업, 다운이 되지 않으며 채널 기억을 위해 사용자가 임의의 자동 프로그램 키를 사용하여 제품의 성능 및 신뢰성이 떨어지는 문제점이 있었다.The present invention relates to an automatic program control apparatus. In the related art, a broadcast is not received when a channel is not stored, and a channel is not up and down, and a user uses an automatic program key to store a channel. There was a problem of poor performance and reliability.

본 발명은 상기와 같은 문제점을 감안하여 메모리 판별부 및 동기판별부 장착하여 채널메모리가 되어 있지 않는 경우에도 자동적으로 프로그램이 되어 채널을 메모리하고 채널 업, 다움을 할 수 있어 제품의 성능 및 신뢰성을 향상시키는 효과가 있다.In view of the above problems, the present invention can be programmed automatically even when the memory discriminating unit and the synchronizing unit are not equipped with a channel memory to memorize the channel and improve the channel performance. It is effective to improve.

Claims

A channel driving state of the storage unit 3 is determined in a television driving circuit in which the microcomputer 2 controls and drives the chroma unit 4 of the tuning unit 1 with the signal of the storage unit 3 storing the channel. The microcomputer 2 by the memory discriminator 5, the clock generator 6 which outputs a clock signal according to the output state of the memory discriminator 5, and the clock signal of the clock generator 6; A synchronization discrimination control unit 8 for controlling the synchronization discrimination unit 9 which discriminates the synchronization signal and outputs the OSD signal to the channel up signal and the chroma unit 4, and the synchronization signal of the synchronization discrimination unit 9 And a synchronization controller 10 for detecting, a clock generator 7 for generating a clock, and a program controller 11 for controlling the automatic program of the microcomputer 2 by the clock generator 7. Automatic program control.
