Abstract

본 발명은 멀티디스크재생시스템의 메모리공유화장치에 관한 것으로, 동영상/음성정보가 기록된 비디오 CD의 정보를 복원처리하는 MPEG오디오/비디오디코더(32, 36)를 갖춘 비디오 CD디스크처리계통과 그래픽정보가 기록된 CDG디스크의 정보를 처리하는 CDG디코더(22)를 갖춘 CDG디스크처리계통을 구비하여 구성된 멀티디스크재생시스템에 있어서, 상기 비디오 CD처리계통과 CDG디스크의 처리계통에 공유가능한 데이터영역을 갖춘 단일의 메모리수단(22a)과, 그 메모리수단(22a)과 상기 비디오 CD처리계통의 경로를 설정하기 위한 제1스위칭수단(44), 상기 메모리수단(22a)과 상기 CDG디스크처리계통과의 경로를 설정하기 위한 제2스위칭수단(46), 현재 재생대상으로 되는 디스크의 종류에 따라 상기 제1스위칭수단(44)과 상기 제2스위칭수단(46)를 선택적으로 스위칭제어하는 제어수단(10) 및 상기 제1스위칭수단(44)의 제어단측에 설치되어 상기 제어수단(10)의 제어하에 상기 제1스위칭수단(44)과 제2스위칭수단(46)의 활성화를 역전시키기 위한 인버터수단(48)을 갖추어 구성된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory sharing apparatus of a multi-disc playback system, comprising a video CD disc processing system and graphic information including an MPEG audio / video decoder (32, 36) for restoring information of a video CD on which video / audio information is recorded. A multi-disc playback system comprising a CDG disc processing system having a CDG decoder 22 for processing information of a recorded CDG disc, comprising: a data area shareable between the video CD processing system and the CDG disc processing system; A single memory means 22a, a first switching means 44 for setting the path of the memory means 22a and the video CD processing system, a path between the memory means 22a and the CDG disk processing system. Second switching means 46 for setting the switching means, and selectively switching the first switching means 44 and the second switching means 46 according to the type of the disc to be reproduced. The control means 10 and the first switching means 44 are provided on the control end side to reverse the activation of the first switching means 44 and the second switching means 46 under the control of the control means 10. Inverter means 48 is configured to be configured.
