Abstract

본 발명은 오디오/비디오정보의 녹화제어방법에 관한 것으로, 단면 또는 양면 레이저디스크(12)에 기록된 정보를 VCR장치(30)에 의해 비디오테이프상에 녹화하기 위해 데이터분리부(24)에 의해 상기 레이저디스크(12)로부터 디스크정보(리드인 정보)가 검출되면 VCR장치(30)의 제어부(34)는 테이프구동메카니즘(24)을 제어하여 비디오신호처리부(36)와 오디오신호처리부(38)에서 처리된 비디오신호와 오디오신호가 비디오테이프상에 녹화되도록 제어하고, 그 레이저디스크(12)의 재생완료시 검출되는 리드아웃 디스크정보에 기초해서 상기 비디오데이프에 대한 녹화를 일시정지시키도록 제어하여 불필요한 배경화면의 녹화를 방지함과 더불러, 경보음발생부(44)와 증폭부(46)에 의해 레이져디스크(12)의 교환시점을 경보함으로써 디스크의 교체를 위해 레이저디스크재생장치(10)의 출력장치인 텔레비전 화면을 주시해야 하는 번거로움이 배제되도록 한 것이다.The present invention relates to a method for controlling recording of audio / video information. The present invention relates to a method of controlling recording of audio / video information by means of a data separator 24 for recording information recorded on a single-sided or double-sided laser disc 12 on a videotape by the VCR device 30. When disc information (lead-in information) is detected from the laser disc 12, the control unit 34 of the VCR device 30 controls the tape driving mechanism 24 to control the video signal processing unit 36 and the audio signal processing unit 38. Control to record the video signal and the audio signal processed by the video tape on the video tape, and pause the recording of the video data based on the readout disc information detected when the laser disc 12 is finished playing. In addition to preventing unnecessary recording of the background screen, the alarm sound generating unit 44 and the amplifying unit 46 alert the point at which the laser disk 12 is replaced, so that the laser disk can be replaced. The hassle of having to watch the television screen as the output device of the playback device 10 is eliminated.
