Abrégé
(EN)
A device for playing digital media comprises a connection for receiving content over a network and a digital rights management ('DRM') module that identifies rights for the received content by accessing a DRM data structure. The DRM data structure can be a temporal cache. The device receives content and the DRM module identifies identifiers associated with the content and/or the device. The DRM module uses the identifiers to access the DRM data structure and identify rights associated with the content. The identified rights are applied to the content to prevent and/or permit activities with respect to the content. Permitted activities for the content may be presented in a display of the device and can be updated as the content changes and/or as rights associated with content change. Content providers and other authorized entities can change the rights associated with particular content by updating the DRM data structure.

L'invention concerne un dispositif de lecture de multimédia numérique comprenant : une connexion pour recevoir un contenu sur un réseau, et un module de gestion de droits numériques (DRM) qui identifie des droits pour le contenu reçu par accès à une structure de données DRM. Ladite structure de données DRM peut être une antémémoire temporelle. Le dispositif reçoit un contenu et le module DRM identifie des identificateurs associés au contenu et/ou au dispositif. Le module DRM utilise les identificateurs pour accéder à la structure de données DRM et identifie des droits associés au contenu. Les droits identifiés sont appliqués au contenu pour empêcher et/ou autoriser des activités par rapport à ce contenu. Les activités autorisées pour le contenu peuvent être présentées sur un affichage du dispositif et être mises à jour lorsque le contenu change et/ou lorsque les droits associés changent. Les fournisseurs de contenu et les autres entités autorisées peuvent changer les droits associés à un contenu particulier par mise à jour de la structure de données DRM.
