Abstract
(EN)
This disclosure describes a dynamic pattern elimination compression method to eliminate redundant patterns, the content of which is not known a priori, by identifying the candidate dynamic patterns and marking them, then checking to see if there are any duplicate occurrences within the entire message by searching for markers, if a marker is found, checking to see if the pattern occurred before, if not, assigning a unique variable to the pattern, if so replacing the pattern with the variable that was assigned for this pattern, and if a pattern is found only once, removing the variable assigned to it.
(FR)
L'invention concerne un procédé de compression par suppression de motifs dynamiques, destiné à supprimer des motifs redondants dont le contenu n'est pas connu a priori, consistant à : identifier les motifs dynamiques candidats et les marquer; vérifier si le message complet contient des apparitions en double en recherchant des marqueurs; en cas d'identification d'un marqueur, vérifier si le motif est déjà apparu; dans le cas contraire, attribuer une variable unique au motif; le cas échéant, remplacer le motif par la variable attribuée à ce motif; et si le motif n'est apparu qu'une seule fois, éliminer la variable qui lui est attribuée.
