Abstract

Un procédé destiné à distribuer un matériau de jeu dans un système d'IPTV est décrit dans la présente invention. Le procédé comprend les étapes consistant à : obtenir, après la réception d'un message de demande de distribution de matériau de jeu, une adresse de source du matériau de jeu selon la demande de matériau de jeu; obtenir une adresse de nœud cible à laquelle le matériau de jeu est distribué selon une stratégie de distribution de matériau; et distribuer directement le matériau de jeu à l'adresse de source au nœud cible qui correspond à l'adresse du nœud cible. La présente invention décrit également un système de distribution de matériau de jeu dans un système d'IPTV qui comprend : une plate-forme de commande qui est utilisée de façon à obtenir l'adresse de source de la base de données de films d'un fournisseur de contenu après la réception d'une demande de matériau de jeu et obtenir une adresse de nœud cible selon une stratégie de distribution de matériau; et un nœud de zone qui est utilisé de façon à sauvegarder le matériau de jeu. Par conséquent, avec le procédé et le système destinés à distribuer un matériau de jeu dans un système d'IPTV fournis dans la présente invention, le matériau est distribué directement depuis l'adresse de source de matériau jusqu'à l'adresse cible, les liens intermédiaires de la distribution de matériaux sont réduits et des copies inutiles du matériau sont évitées. Ainsi le temps de distribution du matériau est réduit de manière évidente.
