Abstract

본 발명은 티브이/브이씨알 복합시스템의 음성편집장치에 관한 것으로, 종래의 티브이/브이씨알 복합시스템에서는 사용자가 음성신호를 편집하기를 원함에도 불구하고 재생시에 음성신호를 편집할 수 있는 음성편집기능, 즉 더빙기능이 없기 때문에, 사용자의 티브이/브이씨알 복합시스템에 대한 편집욕구를 전혀 충족시켜 줄 수 없다는 문제점이 있다. 따라서 본 발명은 외부마이크입력부와 음성믹싱부 및 제2스위치를 이용하여 종래의 티브이/브이씨알 복합시스템에 음성편집기능 즉 더빙기능을 추가함으로써 브이씨알 테이프에 기록되어 있는 영상신호와 음성신호를 재생하면서 그 음성신호만을 편집할 수 있도록 한 것이다.The present invention relates to a voice editing apparatus of a TV / VC composite system. In the conventional TV / VC composite system, a voice editing function that can edit a voice signal at the time of playback even though a user wants to edit the voice signal is provided. That is, since there is no dubbing function, there is a problem in that the user cannot satisfy the editing desire for the TV / V composite system. Therefore, the present invention reproduces the video signal and the audio signal recorded on the VRC tape by adding a voice editing function or dubbing function to the conventional TV / VCAL system using the external microphone input unit, the audio mixing unit and the second switch. While only the audio signal can be edited.
