Abstract: An integrity hash is obtained of rights information stored at a client device. The rights information is associated with content stored at the client device. The integrity hash is encrypted using a client device key to generate an encrypted hash. The client device key is externally inaccessible from the client device. The encrypted hash is stored on the client device.

Abstract: A method of relicensing digital encrypted radio media content transmitted via a network and received by a user electronic device includes receiving a request to relicense an encrypted digital media data file included within digital encrypted radio media content. The encrypted digital media data file is retrieved from the digital encrypted radio media content stored in a memory of the user electronic device. The encrypted digital media data file is decrypted using a radio encryption key to generate an unbound digital media data file. The unbound digital media data file is bound with the user electronic device to generate a bound encrypted digital media data file. The bound encrypted digital media data file is stored in the memory of the user electronic device.

Abstract: A device initialization method includes generating a license request for a personal media device. A timeout indicator may be obtained for a subscription associated with the personal media device. The license request and the timeout indicator may be combined to form a device license for the personal media device. The device license may be digitally-signed to form a signed device license.

Abstract: A method, computer program product and computing device for receiving a request to load at least one new media content item on a personal media device. The size of the at least one new media content item is compared with the amount of storage space remaining on the personal media device to determine if the personal media device has sufficient available storage space. If the personal media device does not have sufficient available storage space, a relative weight associated with at least one old media content item stored on the personal media device is ascertained, the relative weight corresponding to a likelihood that the at least one old media content item will be rendered on the personal media device.

Abstract: A personal media device includes a housing assembly, a display panel located on the housing assembly, and a control assembly located on the housing assembly. The control assembly includes a slider assembly, a first switch assembly positioned proximate a first side of the slider assembly, and a second switch assembly positioned proximate a second side of the slider assembly. The control assembly is configured to extend across substantially an entire width of the housing assembly.

Abstract: In accordance with one embodiment of the present invention, a digital certificate is used to link an arbitrary provisioned right with an associated arbitrary digital action to be performed by a client device on or with respect to a protected digital content object. In one embodiment, the certificate is associated with one or more secure components, which are utilized by the client device in association with performance of the digital action.

Abstract: In one embodiment, an elapsed playback time associated with a digital playback device is determined and compared to an allotted playback time for the device. In the event the elapsed and allotted playback times satisfy a predetermined relationship with respect to one another, further content playback on the device may be denied or otherwise regulated until content playback rights intrinsic to the device are renewed or “recharged”.

Abstract: In accordance with one embodiment of the present invention, secure content objects are transcoded from an input format to an output format based upon identified capabilities of a receiving device. In one embodiment, a plurality of trusted processing components are identified to collectively transcode the secure content object from the identified input format to the determined output format. In one embodiment, each of the trusted processing components are authenticated prior to operating on the secure content object.

Abstract: A system and method for producing and using a protected optical media is described. One feature provides for a compact disc containing digital rights management protection to prevent unauthorized copying of copyrighted materials. Another feature provides for secure copying, storage, transfer, and playback of digital audio content from a protected compact disc or computer storage. Yet another feature provides for a versatile optical media that can be used in both traditional audio compact disc players and in computer CD-ROM drives without risking the security of the content on the media or preventing purchasers from having a robust content experience.
