20160198202, "Digital Rights Management for Segmented Content," assigned to KPN (NL).
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.
20160182466, "TransDRM for Streaming Media," assigned to CodeShop BV (NL)
A method for trans-muxing media content into various consumption formats in a content delivery network, the method comprising the steps of reading a server manifest file, dynamically re-encrypting the media content from the at least one DRM setting into one or more re-encrypted DRM formats, and updating the server manifest file to identify a trans-mux support of the one or more re-encrypted DRM formats. The server manifest file can include a key id and a content encryption key that authorize a re-encrypting of media content, and at least one Digital Rights Management (DRM) setting identifying a source of media content. Other embodiments are disclosed.
