A method and apparatus for brokering the enablement of the communication of encrypted media programs from a plurality of independent broadcasters to a plurality of receivers is disclosed. The system makes use of a pairing key for each provided service, which is differently encrypted by a pairing server and by the broadcaster providing the service. The encrypted versions of the pairing key are decrypted in a first receiver module using information known to the pairing service but not the broadcaster and in a second receiver module using information known to the broadcaster. The pairing key is used to cryptographically bind the first and second receiver modules.

A system and method for increasing the difficulty of cloning high-value software. A system in accordance with the present invention comprises a secure transformation engine, which receives and combines source code and configuration data to generate a software listing, a compiler, coupled to the secure transformation engine, for compiling the software listing and generating a compiled listing, a metadata generator, coupled to the compiler, for integrating hardware specific metadata with the compiled listing to generate an unserialized image, and a serialization server, which receives the unserialized image and serializes the unserialized image using at least pre-programmed values.

An apparatus and method for transmission security is presented. A receiver communicatively coupleable to an identifiable conditional access module (CAM) to enable reception of the service uses an authenticator to control the operability of the receiver according to a comparison between the identified conditional access module and a list of conditional access modules.

An initiation of a purchase is received from a user into a receiver. Receiver software is activated that causes the display of a purchase screen having at least one field. Purchase information is received from the user into the field. The purchase information identifies an initial television subscription service for an initial activation of the receiver and an initial television programming package for the receiver. A secure electronic connection is established with a vendor and the purchase information is transmitted from the receiver to the vendor. A confirmation number is received from the vendor that confirms that the purchase has been allowed. The receiver also receives authorization for the initial activation of the subscription television service, the receiver, and television programming package. The received authorization is then used to activate and configure the receiver to allow the display of the subscription television services.

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 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.

A method, apparatus, and article of manufacture provide the ability to activate functionality in a set-top box. A feature authorization message is received in a set-top box. The feature authorization message comprises one or more rules to be evaluated (wherein each of the rules comprises one or more tests for a status of one or more conditional access module attributes), one or more event requirements for rule evaluation, and one or more features that are dependent by the rule evaluation result (wherein each of the one or more features represents a set of one or more abilities of hardware and/or software of the set-top box). When one or more of the event requirements have been met, the one or more rules are evaluated to obtain a result. The ability to use the one or more features are then set based on the result.

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.
