Abstract

L'invention concerne un procédé de transmission hiérarchique pour réseau de diffusion multimédia mobile, qui consiste en premier lieu à diviser l'ensemble du système de diffusion multimédia mobile en structure de réseau multi-niveau, à configurer une ressource réseau séparée pour chaque réseau dans chaque réseau de niveau. En second lieu, après que le trafic du réseau de niveau supérieur est un flux de données multiplexées, il sera envoyé directement à tous les terminaux dans la zone de couverture du réseau de ce niveau via l'émetteur du réseau de ce niveau, ou aux récepteurs correspondants via les émetteurs du réseau de distribution et du réseau de niveau inférieur. Enfin, le récepteur reçoit des signaux provenant de différents réseaux de manière sélective selon la portée du réseau où il réside. Le procédé, selon l'invention, permet de résoudre le problème de goulot d'étranglement, à savoir que l'autorisation de l'opérateur de réseau doit être obtenue lorsqu'un service doit être envoyé à travers différentes zones, réalisant véritablement le réseau national, ainsi que le service de diffusion national et la combinaison du fonctionnement du réseau national, le réseau local fonctionnant mieux.
