Claims (2)

영상기기에서 무신호 입력시 전원오프 방법에 있어서, 동기신호의 유무를 판별하는 제1과정과, 상기 제1과정에서 동기신호가 없을시 음성신호를 뮤트시킨후 전원을 오프시키는 제2과정으로 이루어짐을 특징으로 하는 무신호 입력시 전원오프 방법.A power-off method when no signal is input from a video device, comprising: a first step of determining whether a synchronization signal is present; and a second step of turning off the power after muting the audio signal when there is no synchronization signal in the first step Power off method when no signal input, characterized in that. 제1항에 있어서, 상기 제2과정이 동기신호가 없을시 음성 뮤트 신호를 생성하여 음성을 뮤트 시키는 과정과, 상기 뮤트 생성과정에서 음성을 뮤트시키고 TV모드 또는 비디오 모드를 판별하는 과정과, 상기 모드 판별과정에서 비디오모드일시 전원을 즉시 오프시키고 TV모드일시 채널을 순차적으로 탐색하여 전채널에 동기신호가 없을시 전원을 오프시키는 과정으로 이루어짐을 특징으로 하는 무신호 입력시 전원오프 방법.The method of claim 1, wherein the second process comprises: generating a voice mute signal to mute the voice when there is no synchronization signal, muting the voice and determining a TV mode or a video mode in the mute generation process; In the mode determination process, the video mode temporary power is turned off immediately and the TV mode temporary channel is sequentially searched to turn off the power when there is no synchronization signal in all channels. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
