Abstract

L'invention concerne un procédé et un système de commande de la génération d'un flux de couches supérieures, par exemple un flux de transport, portant un programme formé d'au moins un flux élémentaire, par exemple un signal audio codé ou un signal vidéo codé. Le flux de couches supérieures est formé de segments en série, par exemple des paquets, contenant des informations spécifiques aux couches supérieures, par exemples des en-têtes, et des segments de données de flux élémentaire. Le débit binaire d'un ou de plusieurs flux élémentaires est adapté à une relation de changement dynamique associant le débit binaire desdits flux élémentaires au débit binaire de la partie du flux de couches supérieures portant ceux-ci.
