Abstract
본 발명은 컴팩트 디스크에 있어서, 라인 그래픽 기능을 수행할수 있는 라인 그래픽컴팩트 디스크 재생장치에 관한 것으로 컴팩트 오디오 디스크 데이타 포맷의 서브코드중 종래에 사용하지 않던 R-W채널을 사용하여 라인그래픽 기능을 수행하는 것을 목적으로 하며 라인 그래픽 메모리와 서브코드 동기신호 검출회로와 R-W오류검출회로와 라인 그래픽 프로세서와 라인 그래픽 표시부를 포함하여 구성되면 컴팩트 디스크의 이용효율을 증가시키는 효과가 있다.The present invention relates to a line graphic compact disc reproducing apparatus capable of performing a line graphic function in a compact disc. It is intended to increase the efficiency of use of a compact disc if it includes a line graphic memory, a sub code synchronous signal detection circuit, a RW error detection circuit, a line graphic processor, and a line graphic display unit.
