Abstract
(EN)
A broadcast data access system is provided for receiving broadcast data by applications residing on a multimedia client, where the broadcast data is a set of modules on a data carousel that are being broadcast over a broadcast network. The broadcast data access system includes an interest manager configured to store a plurality of interests, such that each interest identifies an available module on the data carousel being requested by an application. The system further includes at least one application having registered an interest for a first module with the interest manager, and a dispatcher distributing the first module to the requesting application by accessing the interest manager.

L'invention concerne un système d'accès à des données radiodiffusées qui permet à des applications résidant chez un client multimédia de recevoir des données radiodiffusées. Lesdites données constituent un ensemble de modules sur un train de données diffusées sur un réseau de radiodiffusion. Ledit système comprend un gestionnaire d'intérêt conçu pour stocker une pluralité d'intérêts, chaque intérêt identifiant un module, disponible sur ledit train, demandé par une application. Le système comprend en outre au moins une application ayant enregistré un intérêt pour un premier module à l'aide du gestionnaire d'intérêt, et un répartiteur qui distribue le premier module à l'application de demande par l'accès au gestionnaire d'intérêt.
