Abstract: The present automatic update mechanism provides a method for determining whether computer-readable components loaded within a memory device are at a level of protection specified for protected content that a media application is attempting to process. If a current level of protection provides lower protection that the level specified, a file is updated to achieve at least the level of protection specified by the protected content. Updating the file to achieve the level of protection is performed in a manner that minimizes rebooting of a computing device.

Abstract: The present automatic update mechanism provides a method for periodically checking for updates to support a trusted environment. During the periodic check, an indication from an update service is received if there is a recommended update. Upon receiving the indication, a new revocation list is downloaded from the update service and saved as a pending revocation list. The pending revocation list is then available for on-demand update when protected content requests a higher level of protection on a computing device than the protection provided by a current level of protection on the computing device.

Abstract: A DRM System. A DRM system comprising a service provider, a CE device coupled to the service provider, and an XMR license disposed upon the CE device.

Abstract: To communicate requirements for a digital license from a receiver of corresponding digital content to a computing device upon which the digital content is to be rendered, the receiver tunes the content and locates within the content information relating to the requirements for the license, constructs the requirements from the located information, and sends such constructed requirements to the computing device. The computing device upon receiving the sent requirements constructs the license based on such received requirements, stores such constructed license in a license store of such computing device, and thereafter renders the content only in accordance with the license. Thus, the receiver need not communicate the license itself to the computing device.

Abstract: An enterprise network architecture has a trust link established between two autonomous network systems that enables transitive resource access between network domains of the two network systems. The trust link is defined by data structures maintained by each of the respective network systems. The first network system maintains namespaces that correspond to the second network system and a domain controller in the first network system, or a first network system administrator, indicates whether to trust individual namespaces. An account managed by a domain in the second network system can request authentication via a domain controller in the first network system. The first network system determines from the trust link to communicate the authentication request to the second network system. The first network system also determines from the trust link where to communicate authorization requests when administrators manage group memberships and access control lists.

Abstract: Transmitter and receiver computing device are interconnected by a network. The transmitter transmits protected digital content to the receiver in a manner so that the receiver can access the content even though the content is directly licensed to the transmitter and not the receiver.
