Abstract

본 발명은 하이파이 VTR의 음성녹화/재생장치에 관한 것으로, 외부로부터 입력되는 방송신호는 튜너에서 선국되도록 한 후 음성다중부에서 캐리어의 유무로 음성다중방송신호인가의 여부를 검출하고, 상기의 음성다중부로부터 검출신호를 입력받은 마이크로 프로세서에서는 음성다중방송중 녹화방식에 따른 데이타신호를 서보로 출력하여 데크에서 음성다중임을 나타내는 콘트롤펄스와 함께 음성다중의 방송신호가 녹화되도록하고, 재생시에는 콘트롤펄스를 인식한 마이크로 프로세서에서 데이타신호를 스테레오 음성출력부로 출력함으로써 사용자에 의해 부음성 또는 주음성+부음성이 선택되지 않으면 주음성만 출력되도록하여 사용자의 혼동을 방지토록 한 것이다.The present invention relates to an audio recording / reproducing apparatus of a hi-fi VTR. The broadcasting signal inputted from the outside is tuned by a tuner, and then the audio multiplexing unit detects whether the audio multicasting signal is applied with or without a carrier, The microprocessor that receives the detection signal from the multiple part outputs the data signal according to the recording method during the voice multi-broadcast to the servo so that the voice multi-broadcast signal is recorded together with the control pulse indicating that the sound is multiply from the deck. By recognizing the microprocessor, the data signal is output to the stereo audio output unit so that the main audio is output only when the sub audio or the main audio + sub audio is not selected by the user to prevent confusion of the user.
