Abstract

방송 신호를 수신하는 TV 및 VCR에 있어서, 방송신호 입력상태를 문자신호로 화면에 디스플레이 시켜 현재 수신 조건에 대한 정보를 제공하는 것으로써 튜너 입력과 라인 입력을 스위칭 소자(SW1)에서 선택하고 선택된 영상 신호는 AGC(30)를 통한 후 동기 검출기(40)에서 영상 신호 유무가 검출되어지며 상기 동기 검출기(40)의 출력과 키 입력에 따라 마이콤(50)에서 문자 데이터의 출력과 스위칭 소자(SW1)의 동작을 제어하고 동기 검출기(40)의 출력으로 AGC(30) 출력과 위사 영상 신호 발생기(80)의 출력을 선택한 후 문자 신호를 혼합시켜 출력되게 한 것으로써 방송 수신 상태에 대한 정보를 문자 신호로 화면에 디스플레이 시킬 수 있게 된다.In TVs and VCRs receiving broadcast signals, the broadcast signal input state is displayed on the screen as a text signal to provide information on the current reception condition. The tuner input and the line input are selected by the switching element SW1, and the selected image is selected. After the AGC 30 is detected, the presence or absence of an image signal is detected by the synchronization detector 40, and the output of the text data and the switching element SW1 by the microcomputer 50 according to the output of the synchronization detector 40 and a key input. By controlling the operation of the signal and selecting the output of the AGC 30 and the weft image signal generator 80 as the output of the synchronization detector 40, and then mixed the text signal to output the information on the broadcast reception status text signal Can be displayed on the screen.
