  • Patent number: 8577033
    Abstract: 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.

  • Patent number: 8396216
    Abstract: Systems and method for partial encryption are disclosed. One example method comprises: creating a program association table to include a first program number which identifies a program encrypted in accordance with a first encryption scheme, and a second program number which identifies the same program encrypted in accordance with a second encryption scheme; and creating a program map table for the same program to include first audio and video identifiers associated with the first encryption scheme and second audio and video identifiers associated with the second encryption scheme.

  • Patent number: 8130965
    Abstract: A system and method for the retrieval and transfer of encrypted content from a failed set-top box by a content transcription device. When content is recorded to the storage device of a set-top box, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of the set-top box and a duplicate of the content instance key is encrypted by another public key other than the public key of the set-top. In the event the set-top fails, the encrypted content on the storage device may be retrieved from the storage device by decrypting the duplicate content instance key with the private key that corresponds with the public key that encrypted the duplicate of the content instance key.

  • Patent number: 8095785
    Abstract: 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.

  • Patent number: 7861082
    Abstract: In a subscriber television system having a headend, a server, and plurality of client-receivers, the server, which is remote from the headend, is adapted to receive a validation-message from one or more client-receivers. The validation-message includes content and an authentication-token. The server validates that the sender of the validation-message is a valid client-receiver of the subscriber television system using an authentication-token and a validator that is known to both the server and to at least one of the client-receivers.

  • Patent number: 7860250
    Abstract: A server in a subscriber television network receives service instances from a headend of the subscriber television network. The server is adapted to encrypt according to an encryption scheme and re-transmit service instances to a client-receiver. The server reformats the service instance from a first format into a second format the client-receiver can access the service instance.

  • Patent number: 7805399
    Abstract: The present invention is directed towards providing a partial dual-encrypted stream in a conditional access overlay system. The headend equipment includes an aligner, identifier, and remapper (AIR) device (615) that receives a clear stream and one or two encrypted streams, where the two encrypted streams have been encrypted by two different encryption schemes. The AIR device (615) identifies critical packets associated with the clear stream and subsequently allows two encrypted streams to pass and drops the critical packets of the clear stream. A multiplexer (640) then combines a percentage of the non-critical packets of the clear stream and the critical packets of the two encrypted streams to provide the partial dual-encrypted stream.

  • Publication number: 20090323946
    Abstract: 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.

  • Patent number: 7602914
    Abstract: A system and method for encrypting and recording content to removable storage media for use by multiple set-tops. When content is recorded to the storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of one set-top box and a duplicate of the content instance key is encrypted with the public key of another set-top box. Either set-top box may decrypt the content instance key with the private key that corresponds with its public key so that the encrypted content from the removable storage media may be made available in the clear.

  • Patent number: 7602913
    Abstract: A system and method for retrieval and transfer of encrypted content from a first set-top box utilizing a second set-top box. When content is recorded to the storage device of the first set-top box, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of the first set-top box and a duplicate of the content instance key is encrypted by the public key of the second set-top box. The encrypted content on the storage device may be retrieved by decrypting the duplicate content instance key with the private key that corresponds with the public key of the second set-top box that encrypted the duplicate of the content instance key.
