发明名称 SEGMENTED MEDIA CONTENT RIGHTS MANAGEMENT
摘要 Segmented media content rights management is described. In embodiment(s), a media device can receive segments of protected media content from media content streams that each include a different version of the protected media content. A media content file can be generated to include the segments of the protected media content that are sequenced to render the protected media content for viewing. A file header object can be instantiated in a file header of the media content file, where the file header object includes DRM-associated features, such as one or more DRM licenses, properties, and/or attributes that correspond to the media content file to provision all of the segments of the protected media content together.
