Abstract

La présente invention concerne un procédé de formation de paquets de transport pour la transmission, d'un dispositif serveur vers au moins deux dispositifs clients, de données représentatives d'une séquence d'images codée, les données codées étant encapsulées dans des paquets de transport comprenant une première portion composée d'une pluralité de champs et une seconde portion. Le procédé comprend les étapes d'obtention (E40) d'une information de routage pour chaque dispositif client, et de formation (E43, E45) d'au moins un paquet de transport à partir de données codées, de sorte qu'au moins un champ de la première portion de chaque paquet de transport formé est généré en fonction d'au moins une information de routage obtenue.L'invention concerne également un dispositif de formation de paquets associé, un procédé et dispositifs de transfert et un procédé et dispositif de réception de paquets de transport formés selon le procédé brièvement décrit ci-dessus.
