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.
