Abstract
A content protection query module (CPQM) dynamically queries content protection items supported on the client device. The CPQM automatically identifies content protection configurations, based on the results of the queries. Using a variety of business rules and policies, the CPQM may select a content protection configuration from the configurations for packaging and providing protected content to the client device. The CPQM may instruct the client device to expect the protected content in the selected configuration, thereby enabling the client device to configure itself, as appropriate, for such configuration. The client device may include a media player that selects based on the instructions which DRM module to employ, providing the DRM module with instructions regarding where to obtain decryption keys/licenses for the content, and even instructing the DRM module which decryption mechanism to employ to decrypt the received protected content.
