摘要： A method and apparatus for storing and retrieving program material for subsequent replay is disclosed. The method comprises the steps of receiving a data stream comprising the program material encrypted according to a first encryption key, decrypting the program material; re-encrypting the program material according to a second encryption key; and storing the re-encrypted material in a media storage device. The program material is played back by retrieving the re-encrypted material from the media storage device and decrypting the re-encrypted program material. In one embodiment, the second encryption key is derived from metadata describing replay rights. In a further embodiment, the media storage device also stores the second encryption key which has been further encrypted by a key that is unique to the device used to receive the program material.

摘要： A host receiver and a client receiver are operatively in a direct broadcast satellite system. Program materials received by the host receiver from the direct broadcast satellite system are decrypted by the host receiver. The decrypted program materials are then encrypted at the host receiver using a copy protection key. The copy protection key is encrypted at the host receiver using a host-client pairing key shared between the host receiver and client receiver. The encrypted program materials and the encrypted copy protection key are transferred from the host receiver to the client receiver. The transferred copy protection key is decrypted at the client receiver using the host-client pairing key. The transferred program materials are then decrypted at the client receiver using the decrypted copy protection key.

摘要： A method and apparatus for distributing video content from a direct broadcast satellite system between a host receiver and a client receiver. A family pairing key is transmitted from the direct broadcast satellite system to both the host and client receivers. The family pairing key received by the host and client receivers is decrypted using receiver keys uniquely associated with the host and client receivers, respectively. Decrypted program materials are then encrypted at the host receiver using a copy protection key generated by the host receiver using content information decrypted by the family pairing key. The encrypted program materials are transferred from the host receiver to the client receiver. The encrypted program materials are decrypted at the client receiver using the copy protection key. Like the host receiver, the copy protection key is generated by the client receiver using content information decrypted by the family pairing key.

摘要： Program materials received from a direct broadcast satellite system are distributed between a host receiver and a client receiver for remote decryption. Using either a same pairing key or different host and client pairing keys, an encrypted media encryption key is received at both the host and client receivers, and the encrypted media encryption key is decrypted at both the host and client receivers using the pairing key. Encrypted program materials are received from the broadcast system at the host receiver, and the encrypted program materials are decrypted at the host receiver using the media encryption key. The encrypted program materials are also transferred from the host receiver to the client receiver, where the encrypted program materials are decrypted at the client receiver using the media encryption key.

摘要： A method, apparatus, and article of manufacture provide the ability to process digital media content. A secret key (Ka) is obtained and encrypted into an authorization key message (AKM) message. One or more entitlement keys (Ke) are then obtained and encrypted using the secret key (Ka) as an encryption key into an entitlement management message (EMM). One or more media content encryption keys (Kc) are obtained and encrypted using one or more of the entitlement keys (Ke) as encryption keys into an entitlement control message (ECM). Digital media data content (Dc) is then obtained and encrypted using the one or more media content encryption keys (Kc). The AKM, EMM, ECM, and encrypted digital media data content are then delivered to a set-top box that is configured to provide digital media services with the content.

摘要： A method, apparatus, and article of manufacture limit unauthorized access to digital services. A hidden non-modifiable identification number is embedded into a nonvolatile memory component. The hidden number uniquely identifies a device containing the nonvolatile memory component and access to digital services is based on rights associated with the hidden number. Access to the nonvolatile memory is isolated such that access to the identification number is limited to a fixed state custom logic block. The custom logic block has hardware configured to use the hidden number and other information to provide an output that is a function of the hidden number and that can be used to confirm an identity of a device without revealing information that can be used to impersonate the device.
