Abstract

Dans la présente invention, une lecture d'un contenu configuré par des ensembles de données partielles commence relativement rapidement après l'acquisition d'une pluralité d'ensembles de données partielles de performances ou assimilées. Un dispositif de distribution (10) comprend : un moyen de distribution (122) qui distribue à un dispositif de lecture une pluralité d'ensembles de données partielles (1111), autrement dit de segments de données correspondant respectivement à une pluralité de parties configurant un contenu, et d'ensembles de données de mélange (1121) créés en intégrant au moins deux ensembles de données partielles de la pluralité d'ensembles de données partielles en un seul ensemble de données ; et un moyen de commande (121) qui commande le moyen de distribution d'une manière telle que le niveau de priorité de distribution des ensembles de données de mélange est supérieur au niveau de priorité de distribution de chaque ensemble de données partielles de la pluralité d'ensembles de données partielles.
