摘要： The present invention discloses an apparatus and method for distributing channel key data to an endpoint device. In one example, the present invention provides channel key data to at least one endpoint device prior to the endpoint device being tuned to at least one channel associated with the channel key data. The endpoint device is then informed of the expiration time of the channel key data and is subsequently, upon request, provided the replacement channel key data on a optimized basis (e.g. randomized or utilizing some other optimization algorithm) prior to the expiration time of the original channel key data.

摘要： A process may be utilized by the DVR. The process receives a plurality of segments of a set of content and a plurality of corresponding content rule sets. Further, the process provides one or more instructions to record and encrypt the plurality of segments of the set of content on a storage medium. In addition, the process provides the plurality of content rule sets to the DRM component to be inserted into a locally generated and secured content license associated with the encryption of the set of content. The secured content license includes a master key and a list of the plurality of corresponding content rule sets that have been received in order of reception. The process receives a plurality of marker tokens from the DRM component in order to facilitate trick mode playback.

摘要： A source device determines content rights for encrypted content in the first encoding standard using a first rights data file. The source device creates a second rights data file for transcoded content in the second encoding standard. The source device performs a key management operation including communicating a decryption key for the encrypted content in the first encoding standard to a transcoder. The source device transfers the encrypted content in the first encoding standard to the transcoder. The transcoder decrypts the encrypted content, transcodes the content from the first encoding standard to the content in the second encoding standard, and re-encrypts the content in the second encoding standard using a second encryption key. The transcoder then transfers the encrypted content in the second encoding standard to an indicated device.

摘要： A method and system (100) for providing third party authentication when requesting content and/or services from an application server (106). The method is applicable to key management protocols that utilize the concept of tickets. The method and system include a client (102) being coupled with a third party application server (107), wherein the client submits a request for content from the third party application server and the third party application server returns requested information and corresponding authentication. The client further couples with a first application server (106), wherein the client submits a key request (KEY_REQ) including the third party server information and corresponding authentication to the first application server. The first application server authenticates the third party server information and verifies client authorization based on third party information. The first application server returns a key reply (KEY_REP) if the third party server information is authenticated and client authorization is verified.

摘要： A session rights object and authorization data are used for defining a consumer's access right to a media content stream. The access rights are determined at a caching server remotely located from the consumer rather than locally at the end user site. In a first aspect, in a computing network having a content provider, a key distribution center, a caching server and a client, a method for controlling client access to a real-time data stream from the caching server, is disclosed. The method includes receiving, by the client, a session rights object from a content provider, the session rights object defining access rules for accessing the real-time data stream; receiving, by the client, authorization data from the key distribution center, the authorization data defining the client's access rights to the real-time data stream; forwarding to the caching server the session rights object and the authorization data; comparing, by the caching server, the session rights object with the authorization data to determine client authorization; and if the client is authorized, streaming, by the caching server, the real-time data stream to the client.
