Claims (2)

사용자에 의해 선택되어지는 방송국 코드 또는 방송 프로그램 코드를 마이크로 프로세서에 의해 메모리에 저장하고, 방송신호의 수직 귀선기간에 포함되어 있는 방송국 코드 및 방송프로그램 코드를 수직 귀선신호로부터 데이타 슬라이즈에 의해 분리된 데이타 신호를 데이타 처리부에서 분리하여 다른 메모리에 저장하여, 상기 마이크로 프로세서에서 각 메모리에 저장된 데이타를 순차적으로 비교하여 동일한 경우 상기 다른 메모리에 해당 어드레스에 저장된 방송국 코드의 채널로 절환되도록 구성된 것을 특징으로 하는 텔레텍스트 모드에서 TV모드로의 자동 절환 방식.The broadcasting station code or the broadcasting program code selected by the user is stored in the memory by the microprocessor, and the broadcasting station code and the broadcasting program code included in the vertical return period of the broadcasting signal are separated from the vertical return signal by the data sledding. The data signal is separated from the data processor and stored in another memory, and the microprocessor sequentially compares the data stored in each memory, and in the same case, switches to a channel of a broadcasting station code stored at the corresponding address in the other memory. Automatic switching from teletext mode to TV mode. 상기 특허 청구의 범위 제1항에 있어서, 방송국 코드 또는 방송 프로그램 코드를 전송신호의 수직 귀선 기간중의 몇개의 수평 라인을 이용하여 코드화 신호를 만들어 방송국과 방송프로그램을 비교 식별할 수 있도록 구성된 것을 특징으로 하는 텔레텍스트 모드에서 TV모드로의 자동 절환 방식.The method according to claim 1, characterized in that the broadcasting station code or the broadcasting program code is constructed by using a plurality of horizontal lines during the vertical retrace period of the transmission signal to make a coding signal so that the broadcasting station and the broadcasting program can be identified and compared. Automatically switch from Teletext mode to TV mode. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
