Abstract

La présente invention porte sur un procédé et sur un dispositif permettant de partager un fichier dans un réseau DLNA, ainsi que sur un système DLNA. Le procédé consiste : à acquérir, au moyen d'un serveur multimédia (DMS), une première demande de partage demandant de partager un fichier multimédia et transmise par un premier lecteur multimédia (DMP) ; à déterminer, au moyen du serveur DMS, si le fichier multimédia doit être ou non partagé au moyen d'un second lecteur DMP ; et si le serveur DMS détermine que le fichier multimédia doit être partagé, à sélectionner, à partir d'une table d'enregistrement partagée par rapport au fichier multimédia, un second lecteur DMP et à transmettre un message de redirection au premier lecteur DMP, le message de redirection comportant des informations d'adresse du second lecteur DMP et la table d'enregistrement partagée stockant des informations d'adresse associées à de multiples lecteurs DMP ayant partagé le fichier multimédia.
