Abstract
A DRM server parses a request received from a client for a content identifier and client classification information. The content identifier identifies the requested content and client classification information describes the capabilities of the client. The DRM server determines a policy for the requested content. The policy specifies rules for determining access rights for the content responsive to the capabilities of the client. The DRM server determines access rights for the requested content responsive to the capabilities of the client and the policy. The DRM manager then provides the requested content and the determined access rights to the client.
