Abstract

본 발명은 영상재생 처리장치와 관련된 것으로서, 종래의 이러한 장치에선 CD플레이어등의 디지탈 출력을 합성 중첩하여 TV수상기등에 표출처리하는 수단을 가지고 있지않아 영상 재생처리장치의 이용효율이 저하되고 그 연출 기능을 떨어뜨리게 되는 원인이 되었으나, 본 발명에선 상기와 같은 종래기술의 문제점을 개선할수 있도록, 외부 영상과 내부 DC그래픽 영상 데이타를 중첩처리 제어하는 메인마이콤(17)과, CD그래픽 마이콤(12) 및 디코더부(13), 동기 분리회로(15a) 영상입력 선택 회로(17a)등을 포함하는 영상재생 처리장치를 제공하는데 있다.The present invention relates to an image reproducing processing apparatus. In the related art, such a conventional apparatus does not have a means for synthesizing and superimposing digital outputs such as a CD player on a TV receiver or the like so that the utilization efficiency of the image reproducing processing apparatus is lowered and its directing function. However, in the present invention, the main microcom 17, CD graphics microcom 12, and the like which superimpose and control the external video and the internal DC graphic video data in order to improve the problems of the prior art as described above. An image reproduction processing apparatus including a decoder unit 13, a synchronous separation circuit 15a, an image input selection circuit 17a, and the like is provided.
