Applying digital rights management to multi-media file playback

摘要

A method begins with a processing module of a centralized digital video storage (DVS) system that supports a plurality of subscriber units, receiving a request for playback of a stored multi-media file from a subscriber unit. The method continues with the processing module determining whether the stored multi-media file is a subscription based file or a publically available file. When the stored multi-media file is the subscription based file, the method continues with the processing module accessing digital rights management data regarding subscription based multi-media files to determine the subscriber unit's digital rights to the stored multi-media file. When the subscriber unit's digital rights include playback of the multi-media file, the method continues with the processing module sending a unique copy of the stored multi-media file to the subscriber unit in accordance with a unique slice retrieval pattern of the subscriber unit.
