Abstract
This invention relates to a method and a device providing a content listing comprising a data structure (200) comprising a content listing (CDS) representing a number of media content items (100), where a media content item (100) is represented two times by a first (DRM id(s)) and a second (Dom.ID) representation if the media content item (100) belongs to a specific Digital Rights Management system (DRM) (300; 400) protecting the media content item (100). The first representation (DRM id(s)) comprises an identifier of the type of Digital Rights Management system (DRM) (300; 400) that protects the media content item (100), and the second representation (Dom.ID) comprises the first representation and additional information relating to the identification and/or a state of the specific Digital Rights Management system (DRM) (300; 400) that the media content item (100) belongs to. Hereby, handling of access to a given content item when the given rights related to a content item may differ depending on the state or situation of the DRM content is obtained, since information relating to this may be implemented in the second (or additional)representation. Additionally, it is also possible to provide a single implementation (comprising at least two representations) that can be handled as optimally as possible by both aware and unaware control points.
