Abstract
이 발명은 외부 입력장치로부터 인가되는 오디오/비데오 신호를 무선 주파수 신호로 변조하는 RF 모듈레이터와, 상기 RF 모듈레이터 및 안테나로부터 입력되는 RF 신호를 해당 채널별로 선국하는 튜너와, 상기 튜너로 부터 선국된 신호를 영상 및 음성신호로 검파하여 분리 처리하는 오디오/비데오 신호처리부와, 상기 오디오/비데오 신호 처리부로부터 분리 처리된 신호를 재차 RF 신호로 변조하는 RF 모듈레이터로 구성된 케이블 델레비젼용 컨버터를 구현함으로써, 외부에서 임의로 인가되는 오디오/비데오 신호를 RF 전송신호와 동일하게 신호처리하여 방문객의 확인 영상, 녹화된 영상 및 음성신호를 텔레비젼에 디스플레이할 수 있다.The present invention provides an RF modulator for modulating an audio / video signal applied from an external input device into a radio frequency signal, a tuner for tuning an RF signal input from the RF modulator and the antenna for each channel, and a signal tuned from the tuner. By implementing an audio / video signal converter comprising an audio / video signal processor for detecting and separating the video and audio signals and an RF modulator for modulating the signal separated from the audio / video signal processor into an RF signal again. The audio / video signal randomly applied to the signal may be processed in the same manner as the RF transmission signal to display a visitor's confirmation image, a recorded image, and an audio signal on a television.
