Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

디지탈 비디오 디스크 재생에 관한 기술이다.A technique for playing digital video discs.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

에러정정에 소요되는 불필요한 시간을 줄이는 장치 및 방법을 제공함에 있다.An apparatus and method for reducing unnecessary time required for error correction are provided.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

디지탈 비디오 디스크 재생장치의 에러정정 제어방법에 있어서, 에러의 정정여부를 판단하여 에러가 정정되지 않았으면 메모리 잔량을 판단하여 반복정정 여부를 결정하는 과정과, 반복정정이 결정되면 리-시크 여부를 판단하는 과정과, 상기 판단결과 리-시크로 설정되어 있으면 리-시크후 현재의 에러정정 블럭에서 다시 에러정정을 실시하고, 리-시크로 설정되어 있지 않으면 그래로 현재의 에러정정 블럭에서 다시 에러정정을 실시하는 과정과, 상기 에러의 정정여부 판단시 에러가 정정되었거나 상기 반복정정의 불가 판단시 다음 에러정정블럭에 대한 에러정정을 실시하는 과정으로 이루어짐을 특징으로 한다.In the error correction control method of a digital video disc reproducing apparatus, if the error is not corrected and the error is not corrected, the process of determining whether to repeat the correction by determining the remaining memory amount and re-seeking if the correction is determined is repeated. If it is set to re-seeing, the error correction process is performed again in the current error correction block after re-seeking, and if it is not set to re-seeing, the error is corrected again in the current error correction block. And performing error correction for the next error correction block when determining that the error is corrected or when iterative correction is impossible.

4. 발명의중요한 용도4. Important uses of the invention

디지탈 비디오 디스크 재생시의 에러정정을 제어하는 데 이용한다.Used to control error correction during digital video disc playback.
