Abstract

본 발명은 TV 수상기와 관련된 것으로서, 종래에는 이것의 시청자가 특정채널을 시청하다가 다른 채널의 프로그램을 확인하기 위해서는 신문을 뒤적인다거나, 직접 수조작으로 채널을 전환시켜 봄으로써 다른 프로그램의 내용을 확인할 수 밖에 없어 불편한 것이었다. 본 발명은 상기예의 문제점을 개선할 수 있도록 저렴하고 가벼운 휴대용 TV수상기를 채널스캐닝전용 TV 수상기로 활용할 수 있도록 한 것으로서 이는 특히 이러한 TV수상기의 시시템에는 스위치 전환에 의해 방송채널을 일정시간 간격 순차적으로 자동 스캐닝하는 채널스캐닝부(10)를 구비시킨 구성의 텔레비전수상기의 채널 선국시스템을 제공하는데 있다.The present invention relates to a TV receiver, and in the related art, a viewer of a specific channel checks the contents of another program by searching a newspaper or switching channels by manual operation to check a program of another channel. There was no choice but to be inconvenient. The present invention is to enable a cheap and light portable TV receiver to be used as a channel scanning dedicated TV receiver in order to improve the problems of the above example, in particular the system of such a TV receiver by sequentially switching the broadcast channel by a predetermined time intervals A channel tuning system for a television receiver having a channel scanning unit 10 for automatic scanning is provided.
