Abstract

본 발명은 비디오그래픽어레이(Video Graphics Array)화면상에 다수개의 영사화면을 겹쳐서 표시할 수 있는 화상화면 다중겹침구현회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image screen multiple overlapping implementation circuit capable of displaying a plurality of projection screens on a video graphics array screen.

이 회로는 각 비디오오버레이보드에서 디지탈신호로 변환한 후 화면상에 출력이 가능하도록 R.G.B 디지탈신호로 처리된 다수개의 영상신호를 하나의 화면상에 표시되도록 병렬접속하여 비디오그래픽어레이신호와 조절되어 모니터로 출력됨으로써 다수의 서로 다른 영상신호를 표시할 수 있다.This circuit is controlled by video graphic array signal by connecting multiple video signals processed as RGB digital signal in parallel to display on one screen after converting each video overlay board into digital signal. By outputting a plurality of different video signals can be displayed.
