    摘要： A cable television system provides conditional access to services. The cable television system includes a headend from which service “instances,” or programs, are broadcast and a plurality of set top units for receiving the instances and selectively decrypting the instances for display to system subscribers. The service instances are partially-encrypted using public and/or private keys provided by service providers or central authorization agents. Keys used by the set tops for selective decryption may also be public or private in nature, and such keys may be reassigned at different times to provide a cable television system in which piracy concerns are minimized.

    摘要： A conditional access overlay system utilizing partial encryption without requiring additional program identifiers. The conditional access overlay system generates duplicate critical packets for separate encryption that are sent using the same packet identifier. The rest of the content stream is sent in the clear. However, these duplicated packets are sent without incrementing a continuity counter relative to one another. The overlay packets with non-incremented continuity counter are sent as the second packet immediately following the original critical packet. At the receivers, the incumbent set-top will use the first of the two encrypted packets while the overlay set-top is programmed to use the second of the two encrypted packets. Therefore, methods for verifying alignment of associated packets may be used to distinguish between multiple encryption methods in conditional access overlay systems.

    摘要： A method for determining whether the terminal is authorized to receive the selected service is practiced in a terminal of a conditional access system in which a user selects a service, the selected service being associated with a frequency, the terminal having a tuner and a secure element with at least one authorized entitlement unit number stored therein. The method includes receiving at least one encrypted entitlement control message corresponding to the service, and decrypting each of the at least one encrypted entitlement control message in the secure element, each decrypted entitlement control message revealing at least one first entitlement number associated with the selected service. The method further includes determining that the terminal is authorized to receive the selected service when any first entitlement number of any decrypted entitlement control message represents any number of the at least one authorized entitlement unit number. Alternatively, the method includes receiving at least one entitlement control message corresponding to the service, and authenticating each of the at least one entitlement control message in the secure element, each authenticated entitlement control message revealing at least one first entitlement number associated with the selected service. The method further including determining that the terminal is authorized to receive the selected service when any first entitlement number of any authenticated entitlement control message represents any number of the at least one authorized entitlement unit number.

    摘要： Examples of a system, method, and apparatus for encrypting and recording content are presented. When content is recorded to storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of a first set-top box and a duplicate of the content instance key is encrypted with the public key of other than said first set-top box. A private key corresponding with the public key of the first set-top box may be used to decrypt the content instance key, or a private key corresponding to the public key of other than the first set-top box may be used to decrypt the duplicate of the content instance key so that the encrypted content from the removable storage media may be made available in the clear.
