Abstract
본 발명은 영상가요재생시스템의 음성신호다중화장치에 관한 것으로, 디지탈 오디오채널에 스테레오 반주음이 기록되는 한편 아날로그 오디오채널에 반주음과 가수음성이 혼재되는 형태로 기록된 영상가요매체의 재생이 가능한 영상가요재생시스템에서, 상기 영상가요매체의 디지탈 오디오채널에 기록된 스테레오반주음을 디지탈처리하는 수단(10)과, 상기 영상가요매체의 아날로그 오디오채널에 기록된 스테레오반주음을 아날로그처리하는 수단(12), 상기 디지탈처리된 스데레오반주음과 상기 아날로그처리된 스테레오 반주음을 각기 스위칭출력하는 제1 및 제2스위칭수단(16,18), 이 스위칭수단(16,18)에 의해 설정되는 디지탈모드 또는 아날로그모드와 영상가요모드에서 상기 디지탈 반주음과 상기 아날로그 반주음 및 가수음성을 레벨조정하여 음성다중화처리하는 음성다중화수단(20), 영상가요모드의 수행을 위해 음성입력장치(마이크)의 접속시 정상적인 재생모드로부터 영상가요모드로 스위칭되어 상기 음성다중화수단(20)에서 음성다중화된 다음 제1 및 제2증폭수단(22,24)에서 증폭된 음성다중화 오디오신호를 제3 및 제4증폭수단(30,32)에서 증폭된 다음 출력되도록 하는 제4 및 제5스위칭수단(26,28), 상기 아날로그신호처리수단(12)에 접속되는 아날로그오디오신호의 경로를 설정하는 제3스위칭수단(34), 정상적인 재생모드 또는 영상가요모드에 따라 상기 제1스위칭수단(16)과 제2스위칭수단(18)을 스위칭제어함과 더불어 상기 음성다중화수단(20)에 의해 설정되는 아날로그오디오신호의 레벨을 검출하여 제3스위칭수단(34)을 통과한 아날로그오디오신호를 증폭하는 제5증폭수단(36)의 증폭전압을 제어하는 제어수단(14)을 갖추어 구성된 것이다.The present invention relates to an audio signal multiplexing apparatus of a video flexible playback system, wherein a stereo accompaniment sound is recorded on a digital audio channel, while an accompaniment sound and a mantissa sound are recorded on an analog audio channel. Means for digitally processing stereo accompaniment sounds recorded in a digital audio channel of the image flexible medium, and means for analog processing stereo accompaniment sounds recorded in an analog audio channel of the image flexible medium ( 12) first and second switching means (16,18) for switching and outputting the digitally processed stereo accompaniment sound and the analogly processed stereo accompaniment sound, respectively, the digital set by the switching means (16,18). Mode by adjusting the digital accompaniment sound, the analog accompaniment sound and the mantissa sound in the analog mode or the image flexible mode. When the voice multiplexing means 20 performs the multiplexing operation and the audio input device (microphone) is connected to perform the video flexible mode, the voice multiplexing means 20 switches from the normal playback mode to the video flexible mode and then multiplexes the voice in the multiplexing means 20. And fourth and fifth switching means 26 and 28 for amplifying the voice multiplexed audio signal amplified by the second amplifying means 22 and 24 and then outputting the amplified audio signal by the third and fourth amplifying means 30 and 32. A third switching means 34 for setting a path of an analog audio signal connected to the analog signal processing means 12, the first switching means 16 and the second switching means in accordance with a normal playback mode or an image flexible mode; 18, the fifth amplifying means 36 for detecting the level of the analog audio signal set by the voice multiplexing means 20 and amplifying the analog audio signal passing through the third switching means 34. Control of amplification voltage It is configured and equipped with control means (14).
