Abstract

La présente invention concerne un système et un procédé de plateforme de distribution de contenu à base de publication/abonnement. Le système de plateforme de distribution de contenu comprend : un objet intelligent pour publier un contenu thématique ; un terminal utilisateur pour s'abonner au contenu de thème de l'objet intelligent ; un courtier pour fournir un service pour la publication et l'abonnement du contenu de sujet ; et un serveur composite pour s'abonner au contenu de thème à partir du courtier, mapper le contenu de thème à chaque sujet et virtualiser et stocker ledit contenu de thème, générer un nouveau contenu composite virtuel en effectuant une virtualisation complexe sur le contenu de thème virtualisé, et publier le contenu composite au moyen du courtier.
