Abstract
본 발명은 비디오 카세트 레코우더의 전원 자동 차단방법에 관한 것으로, 종래에는 비디오 카세트 레코우더를 이용하여 방송신호를 시청하거나 비디오 테이프에 기록된 영상/음성신호를 시청하는 중에 비디오 카세트 레코우더의 동작모드를 절환하지 않고 텔레비젼 수상기의 동작모드를 비디오 카세트 레코우더 모드에서 텔레비젼 수상기 모드로 절환하여 텔레비젼 수상기를 시청하는 경우 비디오 카세트 레코우더에 동작전원이 공급되어 불필요한 전력소비되는 결점이 있었다. 본 발명은 비디오 카세트 레코우더의 동작전원이 공급되는가를 확인하는 단계와 ; 상기 단계에서 동작전원이 공급되면 동작전원이 공급된 시간을 카운팅하면서 키 입력이 이루어지는가를 확인하는 단계와 ; 키가 입력되면 비디오 카세트 레코우더를 입력된 키에 대응되는 동작모드로 절환하고 키 입력이 없으면 방송신호가 입력되는가를 확인하는 단계와 ; 방송신호가 수신되지 않으면 카운팅값을 클리어 한 후 카운팅을 시작하고 일정시간이 경과하여도 방송신호가 입력되지 않으면 비디오 카세트 레코우더의 동작전원을 차단하는 단계를 수행하도록 이루어진 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically shutting off power of a video cassette recorder. In the related art, a video cassette recorder is used while a broadcast signal is watched using a video cassette recorder or a video / audio signal recorded on a video tape. When switching the operation mode of the television receiver from the video cassette recorder mode to the television receiver mode without switching the operation mode of the TV receiver, the operating power is supplied to the video cassette recorder, which consumes unnecessary power. . The present invention comprises the steps of checking whether the operating power of the video cassette recorder is supplied; Checking whether a key input is made while counting the time when the operating power is supplied when the operating power is supplied in the step; Switching a video cassette recorder to an operation mode corresponding to the input key when a key is input, and checking whether a broadcast signal is input when there is no key input; If the broadcast signal is not received, the counting value is cleared and the counting starts. If the broadcast signal is not input even after a predetermined time elapses, the operation of the video cassette recorder is cut off.
