CA 2511397

A computing device has instantiated thereon a protected media path for delivering content from a source to a sink. In the protected media path, a media base provides a protected environment in the computing device and includes a common infrastructure of core components effectuating processing of content from any particular source and delivering the processed content to any particular sink, and also includes a policy engine enforcing policy on behalf of the source. The policy corresponds to the content from the source and includes rules and requirements for accessing and rendering the content, whereby the media base allows content to flow through the computing device in a protected fashion, and allows for arbitrary processing of the protected content in the computing device.

Selon l'invention, un dispositif informatique comprend un chemin de supports protégé instancié sur celui-ci et destiné à la distribution d'un contenu d'une source à un bloc récepteur. Dans le chemin de supports protégé, une base de supports définit un environnement protégé dans le dispositif informatique et comprend une infrastructure commune de composants centraux assurant le traitement du contenu à partir de n'importe quelle source particulière ainsi que la distribution du contenu traité à n'importe quel bloc récepteur particulier. Elle comprend également un moteur de réglementation destiné à la mise en application d'une réglementation pour le compte de la source. La réglementation correspond au contenu en provenance de la source et comprend des règles et des exigences pour l'accès au contenu et la restitution de ce dernier. La base de supports permet au contenu de traverser le dispositif informatique de manière protégée et permet un traitement arbitraire du contenu protégé dans ce dispositif informatique.
