In order to improve interactive compression using compression state information, the side information caches of communicating parties must be updated, or synchronized. The present invention is directed to a method of synchronizing side information databases within an interactive compression system comprising two communicating parties comprising the steps of transmitting, from the a first communicating party to the second communicating party, a device hierarchical node index; comparing the device hierarchical node index with a server hierarchical node index and then determining a shared hierarchical node index based on common entries in the two hierarchical node indexes.
En vue d'améliorer la compression interactive au moyen d'informations propres à l'état de compression, les mémoires caches d'informations annexes de parties communiquant peuvent être mises à jour ou synchronisées. La présente invention concerne un procédé de synchronisation de bases de données d'informations annexes dans un système de compression interactive comprenant deux parties communiquant. Ce procédé consiste à transmettre un index de noeuds hiérarchique de dispositif depuis la première partie communiquant à la seconde partie communiquant, comparer ledit index à un index de noeuds hiérarchique de serveur et, puis, déterminer un index de noeuds hiérarchique partagé sur la base d'entrées communes dans les deux index de noeuds hiérarchiques.
