Abstract
본 발명은 외부 영상 신호 및 방송 영상 신호를 서로 간섭하지 않도록 하면서 선택적으로 스위칭하기에 적당하도록 한 영상 기기의 영상 신호 간섭 방지 장치에 관한 것으로, 종래에는 외부 영상 신호 및 방송 영상 신호를 선택적으로 스위칭할 경우 서로 영상 간섭하는 결점이 있었으나, 본 발명에서는 신호 분리부(3)의 영상 신호 및 외부 영상 신호에 뮤트부(9)를 접속시켜 사용하지 않는 영상 신호를 접지로 흘려 뮤트시켜므로써 영상 간섭을 제거하므로 상기 결점을 개선시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing video signal interference of a video device suitable for selectively switching the external video signal and the broadcast video signal without interfering with each other. Conventionally, an external video signal and a broadcast video signal can be selectively switched. In this case, although there is a drawback of interfering with each other, in the present invention, the video signal of the signal separation unit 3 and the external video signal are connected to the muting unit 9 to remove the unused video signal to ground, thereby eliminating image interference. Therefore, the above defects can be improved.
