Title (EN) SECURE LICENSE ENFORCEMENT FOR EXPANDABLE PERIPHERALS ON IOT (SLEEPI) DEVICES
(FR) EXÉCUTION DE LICENCE SÉCURISÉE POUR DES PÉRIPHÉRIQUES EXTENSIBLES SUR DES DISPOSITIFS IOT (SLEEPI)
Abstract:
(EN) Managing playback of a media file, including detecting, while a media file is playing, a trigger mechanism indicating a change in optimal play characteristics of the media file from an original format, wherein the playback of the media file is associated with a first license, in response to detecting the trigger mechanism, instructing a trusted execution environment to request an updated license from a content provider of the media file, and upon receiving a second license for the media file, the trusted execution environment enforces play of the media file using the second license for a second format. The second license allows for the play of the media file to continue at the optimal play characteristics.
(FR) L'invention concerne la gestion de la lecture d'un fichier multimédia, qui consiste à détecter, pendant qu'un fichier multimédia est lu, un mécanisme de déclenchement indiquant un changement de caractéristiques de lecture optimales du fichier multimédia à partir d'un format d'origine, la lecture du fichier multimédia étant associée à une première licence, en réponse à la détection du mécanisme de déclenchement, à donner l'instruction à un environnement d'exécution de confiance de demander une licence mise à jour à partir d'un fournisseur de contenu du fichier multimédia, et après réception d'une seconde licence pour le fichier multimédia, l'environnement d'exécution de confiance exécute la lecture du fichier multimédia à l'aide de la seconde licence pour un second format. La seconde licence permet à la lecture du fichier multimédia de se poursuivre aux caractéristiques de lecture optimales.
