Abstract

본 발명은 브이씨알의 오디오 뮤트장치에 관한 것으로, 종래에는 브이씨알의 재생 또는 녹화시 오디오신호가 일정레벨로 고정되어 있고 뮤트시키기 위해 스틸키나 스톱키를 선택하여 재생이나 녹화화면을 정지시키거나 재생이나 녹화동작을 중지시켜야 하고 다시 동작을 수행하려면 다시 키선택을 하여야 하는 불편함이 있었다. 이러한 점을 감안하여 본 발명에서는 오디오신호처리부에 오디어신호뮤트부를 접속하여 녹화나 재생시 사용자가 오디오 뮤트기능을 선택하면 마이컴의 제어에 따른 일정시간동안 오디오신호를 일정레벨로 뮤트시켜 영상신호를 재생 또는 녹화한다. 따라서, 브이씨알의 녹화나 재생시 오디오 뮤트에 따른 키조작이 단순해지고 브이씨알에서 비디오 테이프의 편집이 가능하다.The present invention relates to an audio mute apparatus of V-Cal. In the related art, an audio signal is fixed at a predetermined level during the playback or recording of a V-Cal, and a still key or a stop key is selected to mute or stop the playback or the recording image. However, it was inconvenient to stop the recording operation and to select the key again to perform the operation again. In view of the above, the present invention connects the audio signal muting unit to the audio signal processing unit, and when the user selects the audio muting function during recording or playback, the audio signal is muted at a constant level for a predetermined time under the control of the microcomputer to generate an image signal. Play or record. Therefore, key operation according to audio muting is simplified when recording or reproducing the VR, and the video tape can be edited in the VR.
