Abstract

본 발명은 캠코더의 오디오 신호 녹음회로에 관한 것으로, 운동경기나 어린이가 놀고 있는 장면등을 원거리에서 촬영할 때 피사체에 간단한 송신장치를 부착하고, 그 송신기에서 전송되는 음성신호를 촬영자가 위치한 캠코더에서 수신하여 이를 기록하기에 적당한 신호로 변환한다음 영상신호와 함께 기록매체에 기록하므로써 다른 도움없이 촬영자가 원거리에서 피사체의 영상과 함께 음성신호를 녹음 할 수 있다.The present invention relates to an audio signal recording circuit of a camcorder, and attaches a simple transmitter to a subject when shooting a sports game or a scene where a child is playing at a distance, and receives a voice signal transmitted from the transmitter from a camcorder where the photographer is located. By converting the signal into a signal suitable for recording, and then recording the recording signal together with the video signal, the photographer can record the audio signal together with the image of the subject from a distance without any help.
