Abstract
본 발명은 현재 사용하고 있는 채널중 가장 큰 채널(13번 채널)을 경계채널로하여 그 경계 채널까지만 채널을 탐색하고 유효채널을 설정하고 또한 탐색한 채널의 수신전계강도의 세기가 너무 강하거나 약한 신호의 해당채널은 자동으로 스킵(skip)하여 원하는 채널만을 기억하도록 하는 텔레비전 수상기의 자동 채널 설정방법을 제공함에 그 목적이 있다.According to the present invention, the largest channel of the currently used channel (channel 13) is used as the boundary channel, and the channel is searched only up to the boundary channel, the effective channel is set, and the received field strength of the searched channel is too strong or weak. It is an object of the present invention to provide an automatic channel setting method of a television receiver in which a corresponding channel of a signal is automatically skipped to store only a desired channel.
상기한 본 발명의 목적을 달성하기 위한 방법은 시청자가 텔레비전 수상기를 구동시키고 자동 채널설정모드를 선택할 경우 방송 동기신호를 검출하는 단계와; 상기 방송동기신호에서 자동이득제어 전압을 검출하여 해당 채널의 정상적인 화면의 자동 이득 제어전압인가를 판단하는 단계와; 상기 자동이득제어 전압이 정상적인 화면의 범위에 속할 경우 채널을 기억한 후 다음 채널을 자동 탐색하고 현재의 채널이 최종채널인지를 판단하여 종료하는 단계;로 이루어짐으로 달성되는 것이다.A method for achieving the above object of the present invention comprises the steps of: detecting a broadcast synchronization signal when a viewer drives a television receiver and selects an automatic channel setting mode; Detecting an automatic gain control voltage from the broadcast synchronization signal to determine whether an automatic gain control voltage of a normal screen of a corresponding channel is applied; If the automatic gain control voltage is within the range of the normal screen, and after storing the channel automatically searching for the next channel, and determining whether the current channel is the last channel to terminate.
