ABSTRACT:
A copy protection comprehending cache catalog with a media jukebox tracks not only the titles of the media themselves, but also the number of copies of each media title, and the copy protection status of each media. When a particular media is not limited to a set number of licensed users, then this media alone is permitted to be used to support multiple users with the hard drive cache in the media jukebox. If, however, a particular media title is limited to one licensed use at a time, per copy of that title, then the hard drive cache is capable of sending data to match the number of copies of media in the jukebox.
