Abstract

본 발명은 2채널의 영상 신호를 동시에 동일 테이프에 기록시 상기 2채널의 음성 신호를 동시 기록할 수 있는 복수채널음성신호 기록장치에 관한 것이다.The present invention relates to a multi-channel audio signal recording apparatus capable of simultaneously recording the two-channel audio signal when two video signals are simultaneously recorded on the same tape.

본 발명은 표준 모드의 1트랙 피치에 2개의 트랙을 형성하여 2채널의영상 신호를 기록가능하게 하는 복수채널 기록장치에있어서, 제 1 제 2채널의 음성 신호를 처리하여 스테레오, 음성 다중 방송에 따라 모노(L+R), 좌, 우 또는 주음성, 부음성으로 각각 분리하는 제 1, 제 2 음성 처리 회로와, 선택 신호(S)에 의해 상기 제 1, 제 2음성 처리 회로에서 각각 출력되는 모노, 좌, 우 또는 주음성, 부음성을 선택하여 출력하는 오디오 스위칭부와 상기 오디오 스위칭부를 통해 출력되는모노 신호를 테이프의 리니어 오디오 트랙에 바이어스 기록하는 리니어 기록 회로와, 상기 오디오 스위칭부를 통해 출력되는 좌, 우 또는 주, 부음성 신호를 테이프의 심층부에 주파수변조 기록하는 하이파이 기록 회로로 구성되어, 2채널의영상 신호를 하나의 테이프에 동시 기록할 경우 상기 2채널에서 나오는 좌, 우, 모노 또는 주, 부음성 기록의 선택폭을 넓혀 재생 음질을 향상시킬 수 있다.The present invention provides a multi-channel recording apparatus for recording two channels of video signals by forming two tracks on one track pitch in a standard mode, and processing audio signals of the first and second channels for stereo and audio multicasting. Therefore, the first and second voice processing circuits respectively separated into mono (L + R), left, right or main audio and sub-audio, and output from the first and second voice processing circuits by the selection signal S, respectively. An audio switching unit for selecting and outputting a mono, left, right or main voice, and a sub-audio, and a linear recording circuit for bias-recording a mono signal output through the audio switching unit to a linear audio track of a tape; It consists of a hi-fi recording circuit for frequency-modulated recording of the left, right, main, and negative audio signals to the deep part of the tape, so that two channels of video signals can be simultaneously recorded on one tape. In this case, playback quality can be improved by widening the selection range of the left, right, mono or main and sub audio recordings from the two channels.
