Claims (1)

VCR이 온이 되어 마이컴(1)의 입력단자(I1)에 '하이'신호가 입력되는가를 검출하여 '하이'상태이면 그의 출력단자(O1)를 통해 '하이'신호를 출력시켜 영상 처리부(2)에 VCR의 CCVS신호가 입력되도록 한다음 키 입력부(3)에서 소정의 키가 눌려져 입력단자(I2)에 인터럽트 신호가 입력되는가를 검출하여 인터럽트 신호가 없으면 종료하되 인터럽트 신호가 있으면 채널 전환키인가를 검출하는 제1과정과;상기 제1과정에서 채널 전환키가 아니면 입력된 키에 해당하는 명령을 수행한 후 종료하되 채널 전환키가 입력되면 출력단자(I1)를 통해 '로우'신호를 출력시켜 영상 처리부(2)에 TV의 CCVS신호가 입력되도록 한 후 채널을 전환시키고, 종료하는 제2과정과;상기 제1과정에 입력단자(I1)에 '로우'신호가 입력되면 키 입력부(3)에서 소정의 키가 눌러져 인터럽트 신호가 입력되는가를 검출하여 인터럽트 신호가 입력된면 눌러진 키가 AV전환키인가를 검출하여 AV전환키이면 출력단자(O1)을 통해 '하이'신호를 출력시켜 영상 처리부(2)에 VCR의 CCVS신호가 입력되도록 한다음 종료하되 AV전환키가 아니면 입력된 키에 해당하는 명령을 수행한 후 종료하는 제3과정으로 이루어짐을 특징으로 하는 VCR스카트 모드시 AV/TV자동 전환 방법.When the VCR is turned on to detect whether the 'high' signal is input to the input terminal I 1 of the microcomputer 1 and outputs the 'high' signal through its output terminal O 1 when the 'high' state is detected. The CCVS signal of the VCR is input to (2), and then a predetermined key is pressed by the key input unit 3 to detect whether an interrupt signal is input to the input terminal I 2 . A first step of detecting whether a switching key is applied; if the channel switching key is not input in the first step , the terminal terminates after performing a command corresponding to the input key, but if the channel switching key is input, A second process of outputting a signal so that the CCVS signal of the TV is input to the image processing unit 2, switching channels, and terminating; a low signal is input to the input terminal I 1 in the first process; When a predetermined key is pressed in the key input section 3, the interrupt The call by detecting the Is input pressing surface with an interrupt signal input binary key to when detecting the applied AV switch key AV change key through an output terminal (O 1) outputs a "high" signal from the VCR to the video processor (2) A method of automatically switching between AV and TV in a VCR mode, characterized in that the CCVS signal is input and terminated, but is terminated after the command corresponding to the input key is terminated. ※참고사항:최초출원 내용에 의하여 공개되는 것임※ Note: The information will be disclosed based on the initial application.
