Abstract

본 발명은 텔레비젼에서의 채널 선국 방법에 관한 것으로서, 이를 위하여, 텔레비젼에서 텔레비젼 방송, 유선 방송 및 라인 입력을 자동으로 절환해 가면서 채널을 선국하는 방법으로서, 채널 업/다운을 위한 키신호가 입력되는지를 체크하여채널 업/다운을 위한 키신호가 입력되면 현재의 모드를 파악하는 제 1단계와; 현재 모드가 텔레비젼 방송 모드이고 입력된 키신호가 채널 업을 위한 키신호이면 텔레비젼 방송 채널을 증가시키면서 채널 선국을 하다가 증가된 텔레비젼 방송채널이 최상위 채널을 벗어나면 라인 입력으로 절환하여 출력하는 제 2단계와; 현재 모드가 텔레비젼 방송 모드이고 입력된 키신호가 채널 다운을 위한 키신호이면 텔레비젼 방송 채널을 감소시키면서 채널 선국을 하다가 감소된 텔레비젼 방송채널이 최하위 채널을 벗어나면 유선 방송 채널의 최상위 채널로 절환하여 출력하는 제 3단계와; 현재 모드가 유선 방송모드이고 입력된 키신호가 채널 업을 위한 키신호이면 유선 방송 채널을 증가시키면서 채널 선국을 하다가 증가된 유선방송 채널이 최상위 채널을 벗어나면 텔레비젼 방송 채널의 최하위 채널로 절환하여 출력하는 제 4단계와; 현재 모드가 유선 방송 모드이고 입력된 키신호가 채널 다운을 위한 키신호이면 유선 방송 채널을 감소시키면서 채널 선국을 하다가 감소된 유선 방송 채널이 최하위 채널을 벗어나면 라인 입력으로 절환하여 출력하는 제 5단계와; 현재 모드가 라인 입력모드이고 인가된 키신호가 채널 업을 위한 키신호이면 유선 방송 채널의 최하위 채널로 절환하여 출력하는 제 6단계와; 현재 모드가 라인 입력 모드이고 인가된 키신호가 채널 다운을 위한 키신호이면 텔레비젼 방송 채널의 최상위 채널로 절환하여 출력하는 제 7단계를 포함하는 텔레비젼에서의 채널 선국방법을 제공함으로서, 채널 업/다운키만으로 기억된 텔레비젼 방송 채널, 유선 방송 채널과 라인 입력 신호를 순차적으로 자동 절환하여 채널 선국을 할 수 있는 편리함을 제공할 수 있는 것이다.The present invention relates to a channel tuning method in a television. To this end, a method for tuning a channel while automatically switching television broadcasting, cable broadcasting, and line input in a television is provided, wherein a key signal for channel up / down is inputted. Checking a current mode when a key signal for channel up / down is input by checking a; If the current mode is a television broadcasting mode and the input key signal is a key signal for channel up, the second step of channel selection while increasing the television broadcasting channel and switching to line input when the increased television broadcasting channel is out of the top channel is outputted. Wow; If the current mode is a TV broadcast mode and the input key signal is a key signal for channel down, the channel is tuned while reducing the TV broadcast channel. When the reduced TV broadcast channel is out of the lowest channel, it is switched to the highest channel of the cable broadcasting channel. Performing a third step; If the current mode is the cable broadcasting mode and the input key signal is the key signal for channel up, the channel is tuned while increasing the cable broadcasting channel. When the increased cable broadcasting channel is out of the top channel, the channel is output to the lowest channel of the TV broadcasting channel. A fourth step of doing; If the current mode is a cable broadcasting mode and the input key signal is a key signal for channel down, channel tuning is performed while reducing the cable broadcasting channel; Wow; A sixth step of switching to the lowest channel of the cable broadcasting channel if the current mode is the line input mode and the applied key signal is a key signal for channel up; If the current mode is a line input mode and the applied key signal is a key signal for channel down, providing a channel tuning method in a television comprising a seventh step of switching to the highest channel of the television broadcasting channel and outputting the channel up / down channel. It is possible to provide convenience for channel selection by automatically switching between a television broadcast channel, a cable broadcasting channel, and a line input signal stored only with a key.
