Abstract

본 발명은 온/오프 시간을 설정하여 온/오프 시간에 픽쳐 온/오프시키는 영상기기에서, 픽쳐 온 시 신호가 있는 채널을 찾아 선국하고 전채널에 신호가 없으면 픽쳐 오프시키는 방법을 제공하는 것으로 종래 픽쳐 온 시 선국된 채널의 신호 유무에 관계없이 디스플레이시킴으로써 신호가 없을 경우 불필요한 전력 낭비를 초래하게 된다.The present invention provides a method of finding and tuning a channel with a signal when a picture is turned on, and turning off a picture when no signal is present in all channels in an image device that sets an on / off time and turns a picture on / off at an on / off time. When the picture is on or off, the channel is displayed regardless of the presence or absence of the signal of the tuned channel, thereby causing unnecessary power waste.

따라서 미리 채널을 설정해 준후 픽쳐 온 시에 설정된 채널을 선국하여 신호가 있으면 그대로 디스플레이시키고 신호가 없으면 채널을 증가시킨후 다시 신호 유무를 체크하게 하여 신호가 있는 채널을 선국하게 하며 전채널에 걸쳐 신호가 없으면 픽쳐 오프시키도록 한 것이다.Therefore, after setting the channel in advance, the channel set up at the time of picture on is tuned and displayed if there is a signal. If there is no signal, the channel is increased and the signal is checked again to tune the channel with the signal. If not, the picture is turned off.

Claims (1)

설정된 온/오프 시간을 현재 시간과 비교하여 온/오프 시간에 픽쳐 온/오프시킴에 있어서, 온/오프 시간 설정시 선국 채널 번호를 설정하는 채널 설정단계와, 픽쳐 온 시 설정된 채널에서의 신호 유무를 판단하여 신호가 있는 경우 화면을 디스플레이시키는 신호 판단 단계와, 상기 신호 판단 단계에서 신호가 없으면 채널을 증가시킨후 최초 설정 채널과 비교하는 채널 비교 단계와, 상기 채널 비교 단계에서 증가시킨 채널과 설정 채널이 같지 않으면 신호 판단 단계를 수행시키고 증가시킨 채널과 설정 채널이 같으면 픽쳐 오프시키는 채널 선택 단계를 수행하도록 한 것을 특징으로 하는 픽쳐 '온'시 자동 선국 방법.A channel setting step of setting a preset channel number at the time of setting the on / off time in the picture on / off time by comparing the set on / off time with the current time, and whether there is a signal in the channel set at the time of picture on A signal determination step of displaying a screen when there is a signal, and a channel comparison step of increasing a channel and comparing it with an initial set channel if there is no signal in the signal determination step, and a channel and a setting increased in the channel comparison step. And performing a channel determining step of performing a signal determination step if the channels are not the same, and performing a channel selection step of turning off the picture if the increased channel and the set channel are the same. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
