Abstract
본 발명은 VCR의 시간데이타 기록 및 재생장치에 관한 것으로, 마그네트 테이프의 제어트랙에 시각데이타를 기록하여 테이프의 위치정보를 시간 정보로 기록재생할 수 있도록 한 시간데이타 기록 및 재생장치를 제공함에 그 목적이 있다.The present invention relates to a time data recording and reproducing apparatus of a VCR, and to provide a time data recording and reproducing apparatus capable of recording and reproducing time position information of a tape by recording time data on a control track of a magnet tape. There is this.
본 발명은 상기 목적을 달성하기 위해 영상신호로 부터 수직동기신호를 검출하는 수직동기신호검출부(1), 상기 수직동기신호검출부(1)의 출력을 1/2분주한 분주기(2), 상기 수직동기신호검출부(1)의 출력을 일정시간 지연시키는 지연부(5), 상기 지연부(5)에 지연된 수직동기신호로 시간데이타를 생성하는 시간데이타 생성부(6), 상기 1/2분주기(2)의 출력과 시간데이타 생성부(6)의 출력을 합성하는 합성부(7), 상기합성부(7)의 출력을 테이프에 기록하기 위한 제어헤드(3)로 구성하고 테이프의 제어트랙에 기록된 데이타를 재생하는 제어헤드(3), 제어헤드(3)에 의해 재생된 신호에서 동기신호를 검출하는 동기신호검출부(8), 검출된 동기신호를 일정시간 지연시키는 지연부(9), 지연부(9)의 출력신호와 상기 제어헤드(3)에 의해 재생된 신호를 사용하여 시간데이타를 재생하는 시간데이타 재생부(10)로 구성함을 특징으로 한다.The present invention provides a vertical synchronous signal detector (1) for detecting a vertical synchronous signal from an image signal, a divider (2) for dividing the output of the vertical synchronous signal detector (1) by 1/2 to achieve the above object, A delay unit 5 for delaying the output of the vertical synchronization signal detection unit 1 for a predetermined time, a time data generation unit 6 for generating time data with the vertical synchronization signal delayed by the delay unit 5, and the 1/2 minute Composed of a synthesizing unit 7 for synthesizing the output of the period 2 and the output of the time data generating unit 6, and a control head 3 for recording the output of the synthesizing unit 7 on a tape, and controlling the tape. A control head 3 for reproducing the data recorded in the track, a synchronization signal detection unit 8 for detecting a synchronization signal in the signal reproduced by the control head 3, and a delay unit 9 for delaying the detected synchronization signal for a predetermined time ), Time data using the output signal of the delay section 9 and the signal reproduced by the control head 3 Characterized in that it consists of a time data reproducing unit 10 for reproducing.
