Abstract
Segmented media content rights management is described. 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.
Claims20
A computer storage device having computer-executable instructions stored thereon that, responsive to execution by a processor, perform a method comprising:
- receiving segments of protected media content from media content streams that each include a different version of the protected media content;
- generating a media content file that includes the segments of the protected media content that are sequenced to render the protected media content for viewing;
- and
- instantiating a file header object in a file header of the media content file, the file header object including DRM-associated features that correspond to the media content file to provision all of the segments of the protected media content together.
A method comprising:
- distributing segments of protected media content from media content streams that each include a different version of the protected media content, the segments of the protected media content being sequenced in a media content file to render the protected media content for viewing at a media device;
- and
- providing DRM-associated features that are included with a file header object in a file header of the media content file, the DRM-associated features corresponding to the media content file to provision all of the segments of the protected media content together.
A method comprising:
- receiving first segments of video content in a standard-definition format from a first video content stream;
- receiving second segments of the video content in a lower-definition format from a second video content stream if available bandwidth decreases;
- and
- receiving third segments of the video content in a higher-definition format from a third video content stream if available bandwidth increases.
