Abstract
소정의 외부 입력단자에서 동기신호가 검출되면 검출된 외부 입력모드로 자동 절환해 주는 외부 입력 자동 절환회로가 개시되는 바, 이는 복수의 외부 입력단자에서 각각 구비되어 비데오 테이프 카세트가 VTR 데크에 삽입되거나 비데오 테이프 카세트가 삽입된 상태에서 재생키가 입력되는 재생모드에서 상기 외부입력단자를 통해 입력되는 동기신호를 검출하는 복수의 동기신호 검출부와, 상기 동기신호 검출부에서 동기신호가 검출되면 텔레비젼의 파워를 첵크하여 스탠바이상태이면 텔레비젼의 파워를 온한 후 동기신호가 검출된 외부 입력단자의 비데오 모드를 수신하기 위해서 현재의 모드를 비데오 모드로 자동 절환하고, 동기신호가 소정 시간동안 입력되지 않을 경우 TV 모드 또는 TV파워 오프모드로 절환하는 제어부로 구성됨으로써, VTR테크에 비데오 테이프 카세트가 삽입되거나 비데오 테이프 카세트가 삽입된 상태에서 비데오 재생키가 입력되면 모든 절환키나 텔레비젼 파원 온 키와 같은 별도의 조작없이 바로 비데오를 시청할 수 있게 되어 유저에게 편리함을 준다.An external input automatic switching circuit for automatically switching to a detected external input mode when a synchronous signal is detected at a predetermined external input terminal is provided, and each of the plurality of external input terminals is provided so that a video tape cassette is inserted into the VTR deck. A plurality of sync signal detectors for detecting a sync signal input through the external input terminal in a play mode in which a play key is input while a video tape cassette is inserted; If the camera is in standby and standby mode, the current mode is automatically switched to the video mode to receive the video mode of the external input terminal where the synchronization signal is detected after the TV is turned on. VTR TECH by the control unit to switch to TV power off mode When the video tape cassette is inserted or a video tape cassette video reproduction key is input, in the inserted state is able to watch the video immediately without further operations such as switching every key-on key pawon TV gives a convenience to the user.
