Abstract

본 발명은 캠코더에 오디오 기능을 부가하는 기술에 관한 것으로, 일반적인 캠코더에서 캠코더 고유의 기능의에 부가적인 기능이 구비되어 있지 않아 사용자가 캠코더를 이용한후, 시간적으로 여유가 있을때 무료하게 시간을 보내야되는 결함을 해소시키지 위하여 캠코더에 라디오 기능을 부가하고, 녹재된 오디오신호를 재생하여 오디오 녹음상태를 자체적으로 체크할 수 있게 하였다.The present invention relates to a technique for adding audio functions to a camcorder, and since a user does not have an additional function of a camcorder-specific function in a general camcorder, a user should spend time freely when there is time after using the camcorder. In order to eliminate the defects, a radio function was added to the camcorder, and the recorded audio signal was reproduced so that the audio recording state could be checked by itself.
