Abstract

La présente invention concerne un procédé pour synchroniser des flux de données sur support dans un réseau de téléphonie mobile à commutation par paquets (1). Selon cette invention, au moins deux flux de données sur support de type différent sont transmis à un terminal (2) dans le cadre de la prestation d'un service de transmission en continu par un serveur multimédia (6). Afin de simplifier la synchronisation des flux de données sur support de type différent, le serveur multimédia (6) transmet au terminal (2) les flux de données sur support de type différent sur une seule liaison (7) utilisant un protocole de transport, sous forme d'un flux de données sur support commun, puis le terminal reçoit le flux de données sur support commun et affiche les flux de données sur support de type différent contenus dans celui-ci. Cette invention concerne également un terminal et un dispositif.
