摘要： A computing device segregates licenses for corresponding content according to relatively short lived licenses for relatively short lived content and relatively long lived licenses for relatively long lived content. The computing device stores the relatively short lived licenses in a more temporary and volatile license store, and the relatively long lived licenses in a more permanent and non-volatile license store. Thus, the relatively short lived licenses are deleted when the temporary license store is turned off and do not create disorder in the permanent license store.

摘要： A sequence of content keys are shared between a receiver of pieces of digital content and a computing device upon which the content is to be rendered. The receiver encrypts each piece of content according to a corresponding content key in the sequence and forwards the encrypted content to the computing device and the computing device decrypts the encrypted content according to the corresponding content key. The receiver initially transmits to the computing device an initialization digital license with an initial content key (CK0) therein. Each of the receiver and the computing device derive a new content key (CKx) in the sequence from the initial content key (CK(0)) in the sequence on an as-needed basis and in a coordinated fashion. The initialization license is required only once for the sequence of content keys, and the receiver need not explicitly communicate (CKx) to the computing device for each piece of content.

摘要： A receiver tunes content and initially does not locate information relating to requirements for a corresponding license, and therefore constructs a default message including default requirements and sends such constructed default message with such default requirements to a computing device that is to render the content. The computing device upon receiving the sent default message with the default requirements constructs a default version of a license based on such received default requirements, stores such constructed default version of the license in a license store of such computing device, and thereafter renders the content only in accordance with the default version of the license.

摘要： A digital license includes an identification of a removal service that can authorize removing such license. A client selects the license to be removed and the service, constructs a challenge including therein a challenge license identification block (LIB) identifying the license to be removed, and sends the challenge to the service. The service receives the challenge, stores at least a portion of the challenge in a database, constructs a response corresponding to the challenge and including therein a response LIB identifying the license to be removed and an identification of the service, and sends the response to the client. The client receives the response, employs the response LIB from the response to identify the license to be removed, and removes the identified license upon confirming that the identification of the service in the identified license matches the identification of the service in the response.

摘要： A computing device has encrypted content and a corresponding license having a decryption key for decrypting the content. The license allows the computing device to render the content thereon. The computing device may issue a sub-license based on the license to a portable device. The sub-license allows the portable device to render the content thereon and has the decryption key. The portable device has a digital device certificate including information thereon. The computing device receives from the portable device the device certificate thereof, and determines based on rules in the license and the information on the portable device in the device certificate whether the computing device can issue the sub-license to the portable device. If so, the computing device constructs such sub-license to include the decryption key (KD) and transmits the constructed sub-license to the portable device.
