In one embodiment, a method for enabling a single assembly of content to be played on a plurality of player devices, each having at least one available digital rights management (DRM) algorithm involves registering a plurality of player devices associated with a client with a database registry, wherein each of the plurality of player devices is enabled to play content using at least one (DRM) algorithm when an appropriate license has been secured; upon registering the plurality of player devices, registering the one or more associated DRM algorithms with each player device; upon receipt of a request for delivery of specified content to the client, searching the database registry for a list of compatible devices and compatible DRM algorithms for the content; obtaining a plurality of licenses to the content, at least one for each DRM algorithm for the player devices associated with the client; obtaining the content from a content provider; and encrypting the content under each of the DRM algorithms to produce multiple DRM selectively encrypted content, wherein, the unencrypted segments of content are assembled together with each of the DRM encrypted duplicate selected segments to produce a single unified content assembly that can be played on any of the player devices. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
