Abstract

본 발명은 비디오 신호의 도시청을 예방하기 위해 스크램블링된 비디오 신호를 디스크램블링을 행할 때 조정하는 CATV 컨버터의 디스크램블러 오프셋 조정회로에 관한 것으로서, 사용자의 요청에 의해 제어신호를 출력하는 제어부와, 상기 제어신호에 따른 오프셋 전압을 디스크램블러로 출력하는 전자 볼륨부로 구성된다. 본 발명은 CATV 컨버터와 이격된 장소에서 리모콘을 이용하여 오프셋 전압을 조정할 수 있고 조정된 오프셋 전압이 디스플레이되기 때문에 다시 오프셋 전압을 조정할 필요가 있을 때 용이하게 조정할 수 있으며, 오프셋 전압을 조정하기 위하여 CATV 컨버터의 내부를 열고 닫아야 하는 불편함이 없어지는 효과가 있다.The present invention relates to a descrambler offset adjustment circuit of a CATV converter that adjusts a scrambled video signal when descrambling to prevent city view of the video signal. The electronic volume unit outputs an offset voltage according to the control signal to the descrambler. The present invention can adjust the offset voltage by using the remote control in a location away from the CATV converter, and the adjusted offset voltage is displayed so that it can be easily adjusted when it is necessary to adjust the offset voltage again, and to adjust the offset voltage The inconvenience of opening and closing the inside of the converter is eliminated.
