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.

Method and apparatus for supporting multiple broadcasters independently using a single conditional access system

A method, apparatus, article of manufacture, and a memory structure for inserting a watermark in a media program is described. In an exemplary embodiment, the method comprises the steps of receiving data comprising the media program in the receiver disposed at a subscriber station, generating a watermark, the watermark generated at least in part according to a secure data processor-unique identifier irreversibly stored in the secure data processor, processing the received data to reproduce the media program, and inserting portions of the generated watermark in the reproduced media program at locations determined at least in part according to the secure data processor-unique identifier to produce a watermarked media program provided for display.

Method and apparatus for hardware-enforced, always-on insertion of a watermark in a video processing path

Hardware-enforced, always-on insertion of a watermark in a video processing path

A method and apparatus for securely and remotely enabling the playing of a media program encrypted by a content encryption key over the Internet is disclosed. A license encryption key and a content decryption key are separately and securely transmitted to the receiver. The license encryption key is stored in the CAM and later used to decrypt the content encryption key so that the media program may be recovered.

Method and apparatus for providing secure internet protocol media services

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.

Secure storage and replay of media programs using a hard-paired receiver and storage device

A system and method for storing and retrieving program material for subsequent replay is disclosed. The method includes accepting a receiver ID associated with a receiver key stored in a memory of the receiver, determining a pairing key for encrypting communications between the conditional access module and the receiver, encrypting the pairing key with the receiver key, and transmitting a message comprising the encrypted pairing key to the receiver. The apparatus comprises a receiver for receiving a data stream transmitting a media program encrypted according to a media encryption key and an encrypted media encryption key and a conditional access module, communicatively coupleable with the receiver.

Method and apparatus for encrypting media programs for later purchase and viewing

A method and apparatus for presenting a media data stream complying with a broadcast encryption standard is disclosed. A dongle is removably coupleable to a rendering device, with the dongle performing transcoding so as to allow presentation of the media in a secure manner without modification of the rendering device software or hardware.

System and method for media transcoding and presentation

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 moduleattributes), 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.

Service activation of set-top box functionality using broadcast conditional access system

A method for tuning used in a broadcast data system having a receiving station with a memory, wherein the receiver station files data and real-time data is disclosed. The method includes storing the memory in a table having tuning information corresponding to a plurality of IP addresses and ports, receiving a download request based on a user input, and using the download request to identify download information including an IP address and a port. The method further includes using the identified IP address and port to open a connection to a socket, using the table to determine tuning information corresponding to the identified IP address and port, and using the tuning information to tune the receiver station to the identified IP address and port.
