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.

1. A method for execution by one or more processing modules of one or more computing devices of a centralized digital video storage (DVS) system that supports a plurality of subscriber units, the method comprises:
receiving a request for playback of a stored multi-media file of a plurality of stored multi-media files from a subscriber unit of the plurality of subscriber units, wherein the centralized DVS system stores the plurality of stored multi-media files as a plurality of dispersed storage error encoded data objects, wherein one of the plurality of dispersed storage error encoded data objects corresponding to the stored multi-media file includes a plurality of sets of encoded data slices, and wherein each of the plurality of subscriber units is assigned a unique slice retrieval pattern; 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, 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; and when the subscriber unit's digital rights include playback of the multi-media file, sending a unique copy of the stored multi-media file to the subscriber unit in accordance with the unique slice retrieval pattern of the subscriber unit, wherein the unique slice retrieval pattern of the subscriber unit indicates a unique pattern for identifying a decode threshold number of encoded data slices of the plurality of sets of encoded data slices.
