Abstract

본 발명은 비디오 컴팩트 디스크 장치의 실행속도 개선방법에 관한 것으로, 비디오씨디의 재생동작중에 트레이오픈 신호가 입력될 경우 트레이오픈 기능을 수행하는 트레이오픈 기능 수행단계와, 이 트레이오픈 기능 수행단계 후에 디스크가 삽입될 경우 삽입된 디스크의 티오씨내에 있는 정보를 읽어들이는 디스크 TOC읽기 수행단계와, 이 디스크 TOC읽기 수행단계 후에 삽입된 디스크가 비디오 컴팩트 디스크인지를 판단하는 디스크 판단단계와, 이 디스크 판단단계후에 삽입된 디스크가 비디오 컴팩트 디스크일 경우 기저장되어 있던 티오씨내의 정보를 읽어들이는 기저장 티오씨 읽기 단계와, 이 기저장 티오씨 읽기 단계 후에 기저장된 티오씨의 정보와 현재 삽입된 디스크에서 읽어들인 티오씨내의 정보가 일치하는지를 비교 판단하는 티오씨 비교판단단계와, 이 티오씨 비교판단단계 중에 판단한 결과 기저장된 티오씨의 정보와 삽입된 디스크 티오씨내의 정보가 일치할 경우는 버전읽기를 즉시 실행하는 버전읽기 단계와, 이 버전읽기 단계 후에 디스크 버전이 V2.0일 경우는 트랙내에 있는 고해상도 정치화상데이터를 읽어들이는 트랙정보 읽기 단계와, 이 트랙정보 읽기단계 후에 디스크 버전 V2.0기능을 실행시키는 버전 V2.0기능 실행단계로 이루어져, 현재 재생중인 디스크의 티오씨내의 정보를 읽어 저장시키고 디스크 교체시 그 교체디스크의 티오씨와 저장되어 있던 티오씨의 정보를 비교 판단하도록 하므로써, 디스크 교체에 따른 복잡한 검색절차 수행없이 신속히 디스크 내장정보를 재생하게 되므로 사용의 편리성을 향상시킬 수 있음은 물론 정보처리 실행시간을 상당히 감소시킬 수 있으므로 이에따라 시스템의 기능성도 증가하도록 된다.The present invention relates to a method for improving execution speed of a video compact disc device, comprising: a tray open function performing a tray open function when a tray open signal is input during a video CD playback operation; and a disk after the tray open function performed. A disc TOC read step of reading information contained in TioC of the inserted disc when a disc is inserted, and a disc determination step of determining whether the inserted disc is a video compact disc after this disc TOC read step; If the disc inserted after the step is a video compact disc, the prestored TOS read step of reading information stored in the pre-stored TioC, and the prestored TIO information and the currently inserted disc after this prestored TIOC read step. Tio comparison comparing the information in Tio read from If the judgment step and the information of the stored TioC and the information in the inserted disk TioC are the same as judged during the TioC comparison judgment step, a version reading step for immediately executing the version reading and a disc version after this version reading step In the case of V2.0, it consists of a track information reading step of reading high resolution static image data in a track, and a version V2.0 function execution step of executing a disc version V2.0 function after this track information reading step. Reads and stores information in TioC of a disc being played and compares the information of TioC and stored Tioc of the replacement disk when replacing a disc, so that disc internal information can be quickly reproduced without performing complicated search procedures following disc replacement. As a result, convenience of use can be improved and information execution time can be significantly reduced. Since yiettara is to increase the system's functionality.
