Claims (1)

무신호 입력시 기록을 자동해제하는 장치에 있어서, 오디오 및 비디오 신호를 입력하는 입출력부(1)와, 상기 입출력부(1)에 결합하여 외부 입력 및 출력을 제어하기 위한 입출력 선택부(2)와, 상기 입출력 선택부(2)에 결합하여 비디오 신호로부터 V동기신호와 C동기신호를 분리하고 상기 C동기신호를 출력하는 C동기 검출기(3)와, 상기 C동기 검출기(3)에 결합되어, 상기 C동기 신호를 수신하여, 재생관련동작제어와 외부 채널선택 및 외부 입력선택 전환제어 출력신호를 출력하는 마이크로 컴퓨터/서보시스템 제어부(4)와, 상기 마이크로 컴퓨터/서보시스템 제어부(4)에 결합하여 상기 마이크로 컴퓨터/서보시스템 제어부(4)로부터의 동기주기동안 상기 C동기신호가 얻어지는 경우에는 기록모드를 유지하고 상기 C동기신호가 얻어지지 않은 경우에도 기록모드를 해제하는 비디오 처리부(6)와,상기 입출력 선택부(6)에 결합하여 상기 마이크로 컴퓨터/서보시스템 제어부(4)로부터의 제어정보를 수신하고 문자정보를 화면상에 표시하는 온 스크린 표시부(5) 및, 상기 비디오 처리부(6)에 결합하여 자기헤드 판독 및 기록하는 신호를 증폭하는 헤드 증폭부(7)로 이루어진 것을 특징으로 하는 무신호 입력시 기록자동해제 방법.An apparatus for automatically releasing recording upon no signal input, comprising: an input / output unit (1) for inputting audio and video signals, and an input / output selection unit (2) for controlling external input and output in combination with the input / output unit (1) Coupled to the input / output selector 2 to separate the V-synchronous signal and the C-synchronous signal from the video signal, and output the C-synchronous signal to the C-synchronous detector 3 and the C-synchronous detector 3. And a microcomputer / servo system controller 4 which receives the C sync signal and outputs a playback related operation control, an external channel selection and an external input selection switching control output signal, and the microcomputer / servo system controller 4. In combination with the C synchronization signal obtained during the synchronization period from the microcomputer / servo system controller 4, the recording mode is maintained and the recording mode even when the C synchronization signal is not obtained. A video processor (6) for releasing the signal, and an on-screen display (5) coupled to the input / output selector (6) for receiving control information from the microcomputer / servo system controller (4) and displaying character information on a screen (5). And a head amplifying part (7) coupled to the video processing part (6) to amplify a signal for reading and writing the magnetic head. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
