LEAN PRIVATE COPY OF MEDIA CONTENT WITHIN NETWORK-BASED DIGITAL VIDEO RECORDINGS

摘要

Described herein are techniques and mechanisms for providing a lean private copy of media content. According to various embodiments, a private copy of a media content item may be made specific to a user account. For example, to use a private copy of a media content item to present that media content item, a client machine may need to first perform operations such as account authentication, content licensing, and device-based DRM. The private copy of the media content item may be significantly deduplicated such that the actual size on disk of the private copy is small relative to the size of the uncompressed media content item. The private copy of the media content item may include reference information which maps the user account associated with the copy to data files associated with the recording.
