摘要： A communication system 10 includes a head end 12. The head end communicates with a system gateway 26. A plurality of user devices 28 is coupled to the gateway 26. The gateway receives the plurality of first encrypted signals, decrypts the plurality of first encrypted signals to form unencrypted signals and encrypts the unencrypted signals with a second encryption to form a plurality of second encrypted signals and communicates the second encrypted signals to the plurality of user devices. The signals may also be super-encrypted signals. That is, rather than un-encrypting at the gateway, the first encrypted signals may be again encrypted.

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 (CW) 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 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.
