Abstract

Dispositif de mise à jour de table de configuration de service à courte durée permettant de mettre à jour la table de configuration de service à courte durée dans les trames de multiplexage du support de service. Le dispositif de mise à jour de table de configuration de service à courte durée comprend une unité d'analyse et une unité de comparaison. L'unité d'analyse reçoit la trame de multiplexage du support de service et analyse l'en-tête de la trame de multiplexage reçue pour obtenir le champ spécifique. L'unité de comparaison compare le champ spécifique obtenu par l'unité d'analyse avec le numéro de séquence de mise à jour de la table deconfiguration de service dans la table de configuration de service à courte durée qui est enregistrée dans l'unité de comparaison, et effectue le traitement correspondant en fonction du résultat de la comparaison. Le dispositif de mise à jour de la table de configuration de service à courte durée peut être appliqué dans un terminal de diffusion multimédia mobile.
