Abstract

본 발명은 비디오-컴팩트디스크 플레이어에서 컴팩트디스크인터렉티브-디지탈비디오(CDI-DV 이하'CDI-DV'라 칭한다.)를 재생하는 방법에 관한것으로, 외부로부터 컴팩트디스크의 재생신호가 입력되면 마이크로컴퓨터는 드라이브 내에 있는 컴팩트디스크가 CDI 방식인지 여부를 판단하는 단계와, CDI방식이 아니면 기존의 방식대로 TOC를 읽어 저장하여 재생하는 단계와, CDI방식의 디스크이면 파일 구조 볼륨 디스크립터를 찾아 단계와, 패스 테이블의 주소를 읽는 단계와, 패스테이블로 점프하는 단계와, 각각의 패스테이블의 디렉토리를의 시작주소를 읽어 저장하는 단계와, 상기 단계에서 저장된 시작 주소를 이용하여 각각의 디렉토리의 시작위치로 점프하여 디렉토리 리코더를 찾는 단계와, 이후 각각의 파일 중 엠펙 데이타 파일만을 트랙으로 순차적으로 등록하는 단계와, VCD의 경우처럼 트랙의 주소부터 재생을 시작하는 단계를 순차적으로 수행하는 간단한 프로그램으로 CDI-DV를 재생할 수 있도록 함으로써 매우 유용하다.The present invention relates to a method of playing a compact disc interactive-digital video (hereinafter referred to as "CDI-DV") in a video compact disc player. Determining whether the compact disc in the drive is a CDI method; reading, storing, and playing a TOC according to a conventional method, if not a CDI method; and finding a file structure volume descriptor if the disk is a CDI method; Reading the address of, jumping to the passtable, reading the starting address of each passtable's directory, and jumping to the start of each directory using the start address stored in the step. Locating the directory recorder, and subsequently only the MPEG data file of each file is sequentially tracked. The steps of starting playback from the address of the track, as in the case of VCD for registering in a simple program to perform in sequence is useful to be able to play by the CDI-DV.

How to Play Compact Disc Interactive Digital Video on Video Compact Disc Players

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제3도는 본 발명 비디오-컴팩트디스크 플레이어에서 컴팩트디스크인 터렉티브-디지털비디오를 재생하는 기능을 가진 컴팩트 디스크 플레이어의 동작 흐름도이다.3 is an operation flowchart of a compact disc player having a function of playing interactive-digital video, which is a compact disc, in the video-compact disc player of the present invention.

Claims

When the play signal of the compact disc is input from the outside, the microcomputer determines whether the compact disc in the drive is a compact disc interactive (CDI) method. Reading, storing, and playing back a table of content (TOB), finding a file structure volume descriptor for a CDI disk, reading an address of a pass table, and jumping to a pass table. And reading and storing the start address of the directory of each passtable, and finding the directory recorder by jumping to the start position of each directory using the start address stored in the step, and then each file. Registering MPEG data files as tracks sequentially, starting with the track address as in the case of video compact discs. A method of reproducing a digital video-compact disk of teorek creative in compact disc players - the step of starting the raw video, characterized by carrying out sequentially.
