Claims (1)

  1. 다수의 VTR을 구비한 광화상회의 시스템에 있어서, 교환기를 통하여 소정의 가입자 번호로 출력되는 DTMF 신호를 수신하여 소정의 디지털데이타로 변환하여 출력하는 DTMF 리시버(100)와, 상기 DTMF 리시버(100)에서 출력되는 상기 디지털 데이타를 디코드하여 소정의 기능선택 신호를 출력하는 디코더(200)와, 상기 디코더(200)에서 출력되는 상기 기능선택 신호를 입력하여 상기 VTR의 전원을 온／오프하기 위한 제어신호를 발생하는 전원제어회로(300)와, 상기 디코더(200)에서 출력되는 상기 기능선택 신호를 입력하여 상기 VTR의 기능을 선택하기 위한 제어신호를 발생하는 기능제어회로(400)로 구성함을 특징으로 하는 VTR 원격조정장치.
