Abstract

L'invention se rapporte à des protocoles de messagerie conçus pour être utilisés entre des composants d'un système de fourniture de guides de programmes interactifs (IPG). Un tel protocole permet d'utiliser plus efficacement la largeur de bande finie disponible pour la distribution de séquences vidéo de IPG. Une réalisation de l'invention comprend des protocoles de messagerie permettant la communication entre un gestionnaire de session (702), un générateur de trains de transport (704) et un terminal d'abonné (706). Ce protocole de communication du générateur de trains de transport (704) vers le terminal d'abonné (706) spécifie le contenu pour une table d'indexation de la diffusion à la demande qui peut être transmise au sein d'une section privée d'un train de transport MPEG. Ce contenu inclut une liste de trains de données disponibles de diffusion à la demande. Le protocole de communication du terminal d'abonné (706) vers le gestionnaire de session (702) inclut des messages d'acquisition, de communication et de demande. Le protocole de communication du gestionnaire de session (702) vers le générateur de trains de transport (704) inclut des messages de communication de trains de données, de demandes de trains de données et de remise à zéro, et le protocole de communication du générateur de trains de transport (704) vers le gestionnaire de session (702) inclut des accusés de réception de ces messages.
