Title (EN) DIGITAL RIGHTS MANAGEMENT FOR SEGMENTED CONTENT
(FR) GESTION DE DROITS NUMÉRIQUES POUR CONTENU SEGMENTÉ
Abstract:
(EN) A method and a system for enabling delivery of at least part of a digital rights management (DRM) protected segmented content item to a content processing device is described wherein segmented content item is associated with a manifest file, comprising at least a first segment identifier associated with a first segment being encrypted on the basis a first key; and, a second segment identifier associated with a different, second, segment being encrypted on the basis of a second key; said manifest file further comprising key information for enabling decryption of at least one of said first and second encrypted segments. Said method may comprise: a secure module, preferably a DRM module, in said content processing device requesting a DRM server access to at least part of said segmented content item; and, providing said secure module access to at least part of said key information, if said content access request is granted by said DRM server.
(FR) L'invention concerne un procédé et un système pour permettre la fourniture d'au moins une partie d'un élément de contenu segmenté protégé par gestion de droits numériques (DRM) à un dispositif de traitement de contenu, l'élément de contenu segmenté étant associé à un fichier de manifeste comprenant au moins un premier identificateur de segment associé à un premier segment qui est chiffré avec une première clé, et un deuxième identificateur de segment associé à un deuxième segment, différent, qui est chiffré avec une deuxième clé; ledit fichier de manifeste comprenant également des informations de clé permettant le déchiffrement d'au moins un desdits premier et deuxième segments chiffrés. Ledit procédé peut consister : à ce qu'un module sécurisé, de préférence un module DRM, présent dans ledit dispositif de traitement de contenu, demande l'accès par un serveur DRM à au moins une partie dudit élément de contenu segmenté; et à donner audit module sécurisé l'accès à au moins une partie desdites informations de clé, si ladite demande d'accès au contenu est honorée par ledit serveur DRM.
