Abstract:
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.
