Abstract

La présente invention concerne un système pouvant fournir une émission radiodiffusée en même temps que des contenus associés à ladite émission. Elle concerne en particulier un système de fourniture de services de portail radiodiffusés qui synchronise des contenus d'émission diffusés en mode continu provenant de plusieurs sources d'émission avec des contenus diffusés en mode non continu se rapportant à diverses émissions diffusées à partir de plusieurs sources d'émission en mode non continu, par l'intermédiaire de réseaux informatiques câblés ou sans fil, tels qu'Internet, de manière à fournir aux utilisateurs des émissions interactives temps réel. Le système de fourniture de services de portail radiodiffusés de l'invention, en tant que partie d'un système intégré de prestation de services, comprend un serveur de services (210) qui traite les contenus diffusés en mode non continu reçus tant de fournisseurs de contenus diffusés en mode non continu (T/ICP) (230) que de fournisseurs de contenus diffusés en mode continu (SCP) (220), offre un site de fourniture de services de portail permettant de rechercher dans la base de données les contenus diffusés en mode non continu se rapportant à des émissions radiodiffusées demandées par l'utilisateur, et de produire lesdits contenus. Le système comprend également une application de visualisation intégrée (33) permettant de jouer en temps réel les contenus diffusés en mode continu reçus des fournisseurs de contenus diffusés en mode continu (SCP) (220), de recevoir de la base de données les contenus diffusés en mode non continu dans un serveur de services (210), et de jouer en temps réel les contenus diffusés en mode non continu en même temps que les contenus diffusés en mode continu, de façon à présenter lesdits contenus.
