Abstract

본 발명은 일반적인 비디오 시디 플레이어에서 재생 가능한 CD-DA, CD-G, 비디오 시디 디스크 이외의 시디-아이 디지탈비디오(DV) 디스크도 재생 가능토록 한 시디-아이 디지탈비디오 디스크 재생방법에 관한 것이다.The present invention relates to a method for reproducing a CD-DA digital video disc, such as a CD-DA, a CD-G and a video CD disc, which can be reproduced by a general video CD player.

이러한 본 발명은 디스크가 삽입되면 TOC영역의 AO PSEC 위치를 판독하여 디스크의 종류를 판별하고 그 판별한 디스크의 종류가 시디-아이 디스크일 경우 디스크의 라벨을 판독하는 제1과정과; 디스크의 라벨중 경로 테이블을 읽어 물리적인 어드레스를 계산하는 제2과정과; 계산한 물리적 어드레스로 디렉토리 블럭 어드레스를 탐색하고 그 탐색한 디렉토리 블럭 어드레스에 기록되어 있는 디렉토리 레코드를 해석하는 제3과정과; 디렉토리 레코드를 해석하여 엠펙 화일의 시작점을 찾고 재생시 상기 엠펙 화일의 시작점부터 재생을 행하는 제4과정을 순차 실행시키게 되는 것이다.The first aspect of the present invention includes a first step of reading the AO PSEC position of the TOC area when the disc is inserted to discriminate the disc type and reading the label of the disc if the disc type is a CD-I disc; A second step of calculating a physical address by reading the path table among the labels of the disc; A third step of searching for a directory block address with the calculated physical address and interpreting the directory record recorded in the searched directory block address; A fourth step of searching for a start point of the MPEG file by interpreting the directory record, and reproducing from the starting point of the MPEG file at the time of reproduction.

Claims

Reading the AO PSEC position of the TOC area when the disc is inserted to discriminate the disc type and reading the label of the disc if the discriminated disc type is a CD-I disc; A second step of calculating a physical address by reading a path table among the labels of the disk; A third step of searching for a directory block address with the calculated physical address and analyzing a directory record recorded in the searched directory block address; And a fourth step of analyzing the directory record to find the starting point of the MPEG file and playing back from the starting point of the MPEG file at the time of reproduction.
