Abstract
본 발명은 음성다중 텔레비젼 방송을 시청하다가 브이씨알을 사용하여 녹화하는 경우 한쪽 채널로는 우리말(또는 영어)로 방송을 시청하고 다른 한쪽 채널로는 영어(또는 우리말)로 기록하여 테이프 재생시 처음 시청시와 다른 언어로 들을 수 있도록 함으로써 어학학습에 도움을 줄 수 있도록 한 오디오/비디오 기기의 음성다중채널에 의한 기록장치 및 방법에 관한 것으로, 입력되는 FM음성의 중간 주파를 검파하는 음성중간주파 검파부(20), 음성 중간주파 검파부(20)로부터 주(L)신호를 일정레벨로 증폭하는 주신호 증폭부(21), 음성주간주파 검파부(20)로부터 부(R)신호를 검파하는 부신호 증폭부(22)와, 음성다중 선택 및 라인출력을 선택하고 이에따른 제어신호를 입력시키기 위한 키 입력부(23), 주신호증폭부(21)와, 부신호증폭부(22)의 신호를 상기 키입력부(23)로부터의 제어신호에 따라 스위칭 및 제어부(24), 스위칭 및 제어부(24)의 출력중 일정대역의 신호만 통과시켜 텔레비젼의 좌측스피커(26)로 출력시키는 제1로우패스필터(25), 스위칭 및 제어부(24)의 출력중 일정대역의 신호만 통과시켜 텔레비젼의 우측스피커(27)로 출력시키는 제2로우패스필터(28), 스위칭 및 제어부(24)의 출력중 일정대역의 신호만 통과시켜 라인출력으로 내보내는 제3로우패스필터(29)로 이루어진다.According to the present invention, when a voice TV is recorded and then recorded using V-CAL, the broadcast is watched in Korean (or English) on one channel and the English (or Korean) is recorded on the other channel, which is the first time when the tape is played. The present invention relates to a recording device and a method using a multi-channel audio / video device for aiding language learning by allowing a user to listen to a language other than poetry. A main signal amplifying unit 21 for amplifying the main (L) signal to a predetermined level from the voice middle frequency detector 20, and a negative (R) signal from the negative frequency detection unit 20 is detected. Signals of the sub-signal amplifier 22, the key input unit 23, the main signal amplifier 21, and the sub-signal amplifier 22 for selecting the voice multiple selection and the line output and input a control signal accordingly. Key In response to the control signal from the unit 23, the first low pass filter 25 for passing only signals of a predetermined band among the outputs of the switching and control unit 24 and the switching and control unit 24 and outputting them to the left speaker 26 of the television. ), The second low pass filter 28 which passes only a signal of a predetermined band during the output of the switching and the control unit 24 to the right speaker 27 of the television, and a signal of a certain band during the output of the switching and control unit 24. It consists of a third low pass filter 29 that passes through only to pass through the line output.
