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 is provided by which a client device obtains authorized access to content delivered over a content delivery network. The method includes receiving an entitlement management message (EMM). The EMM includes at least one cryptographic key and a device registration server certificate ID (DRSCID) identifying a currently valid device registration server (DRS) public key certificate. The DRSCID obtained from the EMM is compared to a stored DRSCID value. An entitlement control message (ECM), which includes an encrypted traffic key for decrypting content, is received. If the DRSCID obtained from the EMM is determined to match the stored DRSCID, the traffic key is decrypted with the cryptographic key or a key derived from the cryptographic key to thereby access the content.

摘要： A process is provided. The process determines member devices in a domain of devices. Further, the process encrypts a set of content with a content encryption key to generate an encrypted set of content. In addition, the process encrypts the content encryption key with each of a plurality of pre-fetch keys to generate a plurality of encrypted content encryption keys. Each of the pre-fetch keys corresponds to a member device in the domain of devices. Finally, the process stores each of the encrypted content encryption keys in a content license corresponding to a member device in the domain of devices. The encrypted content may be stored on a removable medium. Further, the process allows another device to play back the content from the same removable medium.

摘要： A method and apparatus are provided for enabling a Universal Plug and Play (UPnP) device to be automatically provisioned to access services without the need for manual interaction. In accordance with the invention, when a UPnP device needs to be provisioned, it automatically obtains pre-provisioning information from a provisioning device on the home network, and uses the pre-provisioning information to interact with the provisioning device to cause the UPnP device to be provisioned. The provisioning enables the UPnP device to access services, including digital rights management (DRM) services, over a network.
