Abstract

이 발명은 TV 화면상에 수신되는 전체 채널에 해당되는 방송 화상이 디스플레이되도록 하여 그 선택을 용이하고 신속하도록 한 TV수상기의 채널선택장치에 관한 것이다.The present invention relates to a channel selection apparatus of a TV receiver, in which a broadcast image corresponding to all channels received on a TV screen is displayed so that selection thereof is easy and quick.

이 발명은 안테나(ANT)또는 케이블(CAB)를 통해 수신되는 신호중 소망하는 신호만을 소정주파수에 동조하는 튜너부(10);상기 튜너부(10)를 통해 입력되는 신호중 키입력부(30)를 통해 등록된 채널만을 자동으로 선택하여 주는 채널자동선택부(20); 상기 채널자동선택부(20)에 채널검색을 위한 채널설정명령, 검색시장명령등을 키입력하여 주는 키입력부(30); 상기 채널자동선택부(20)에서 출력되는 선택된 채널신호를 중간주파수(IF) 처리하는 중간주파수처리부(40); 상기 중간주파수처리부(40)에서 출력되는 선택된 채널의 화상을 순간화상단위로 저장하는 순간화상저장부(50); 및 상기 순간화상저장부(50)에서 전송되어온 화상신호가 CRT상에 순차적으로 디스플레이되도록 제어하는 CRT부(60);를 포함하여 구성된다.According to an embodiment of the present invention, a tuner unit 10 tunes only a desired signal among signals received through an antenna ANT or a cable CAB to a predetermined frequency; and a key input unit 30 of signals input through the tuner unit 10. A channel automatic selection unit 20 for automatically selecting only a registered channel; A key input unit 30 for inputting a channel setting command for searching a channel, a search market command, etc. to the channel automatic selection unit 20; An intermediate frequency processor (40) for processing an intermediate frequency (IF) of the selected channel signal output from the channel automatic selection unit (20); An instantaneous image storage unit 50 for storing the image of the selected channel output from the intermediate frequency processor 40 in an instant image unit; And a CRT unit 60 which controls the image signals transmitted from the instant image storage unit 50 to be sequentially displayed on the CRT.

따라서, 이 발명은 50여개의 에어방송 및 케이블방송에 대한 방송내용을 한 화면에서 동시에 검색할 수 있게 되어 채널 선택이 용이할 뿐 아니라 국산 TV시스템의 수출효과중 마케팅 포인트로서 이용이 가능한 효과가 있다.Therefore, the present invention can search the broadcast contents of about 50 air and cable broadcasts simultaneously on one screen, which makes it easy to select channels and can be used as a marketing point among export effects of domestic TV systems. .
