Abstract

1.청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

컴팩트디스크를 재생하는 장치에 관한 것이다.A device for reproducing a compact disc.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

단일의 컴팩트디스크 재생장치에서 각종의 컴팩트디스크들(CD-I와 비디오CD, 포토CD와 비디오CD, 디지탈오디CD와 그래픽CD)을 식별한다.In a single compact disc player, various compact discs (CD-I and video CD, photo CD and video CD, digital audio CD and graphic CD) are identified.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명의 CD판별방법은 CD상의 TOC영역의 A0위치에 기록되어 있는 PSEC정보를 분석하여 CD-I유형의 디스크 혹은 컴팩트디스크 인터액티브 브리지 유형의 디스클를 일차적 판별하고, 상기 일차적으로 판별된 각각의 결과들 및 CD의 2초 16프레임상에 기록되어 있는 경로테이블에 VCD디렉토리가 존재하는지 여부를 이용하여 CD-I와 비디오CD를 구별하고, 포토CD와 비디오DC를 구별하는 것을 특징으로 한다.The CD discrimination method of the present invention analyzes the PSEC information recorded at the A0 position of the TOC area on the CD to discriminate the disc of the CD-I type disc or the compact disc interactive bridge type and to determine the discs of the primary discriminated type. The CD-I and the video CD are distinguished from each other by using the results and whether or not the VCD directory exists in the path table recorded on 2 seconds and 16 frames of the CD.

4. 발명의 중용한 용도4. Significant use of the invention

각종의 컴팩트디스크를 재생하기 위한 장치.A device for reproducing various compact discs.
