Abstract

본 발명은 가전기기 등의 채널선국 시스템과 관련된 것으로서, 종래에는 지역적으로 다수개 할당된 방송 채널의 각개 채널프로그램이 어떠한 것이 방송되고 있는가를 확인할려면 신문매체를 통해 확인하던가 또는 수많은 채널을 수조작으로 일일이 선택하여 확인할 수 밖에 없는 환경이어서 이에따른 불편을 피할 수 없다는 문제점이 있었다.The present invention relates to a channel selection system such as a home appliance, and in the related art, in order to check what is being broadcasted by each channel program of a plurality of broadcast channels allocated locally, it is necessary to check through a newspaper medium or manually operate a large number of channels. There was a problem that can not be avoided by following the environment that can not be selected and confirmed.

본 발명은 이러한 문제점을 개선할 수 있도록 리모콘 송신기나 또는 T.V수상기 세트 등에는 다수개의 방송채널을 일정한 수순으로 일정시간 만큼 자동으로 전환시킬수 있도록한 채널스캐닝로직(1)을 구비시킨 구성의 가전기기의 채널자동 스캐닝시스템을 제공하는데 있다.The present invention provides a home appliance having a channel scanning logic (1) equipped with a channel scanning logic (1) for automatically switching a plurality of broadcast channels in a predetermined sequence in a remote control transmitter or a TV receiver set to solve such a problem. It is to provide a channel automatic scanning system.
