Abstract
(EN)
The present invention relates to a data compression method, and more specifically to a data compression method which can improve data compression rates by running, in parallel, a method in which a string dictionary is created and an index is stored and a method in which compression codes for the strings are stored when data is to be compressed. According to the present invention, compression rates are improved and decompression rates are effectively raised.

La présente invention concerne un procédé de compression de données, et plus spécifiquement un procédé de compression de données qui peut améliorer les taux de compression des données en exécutant, en parallèle, un procédé selon lequel un dictionnaire de chaînes est créé et un index est stocké, et un procédé selon lequel les codes de compression des chaînes sont stockés lorsque les données doivent être compressées. Selon la présente invention, les taux de compression sont améliorés et les taux de décompression sont efficacement augmentés.

본 발명은 데이터의 압축방법에 관한 것으로서, 보다 상세하게는 컴퓨터 데이터를 압축할 때 문자열 사전을 생성하여 인덱스를 저장하는 방법과 문자열에 대한 압축코드를 저장하는 방법을 병행함으로써 압축률을 향상시킬 수 있도록 하는 데이터의 압축방법에 관한 것이다. 본 발명에 따르면 압축률이 향상되고 압축 해제시의 속도가 빨라지는 효과가 있다.
