摘要:
A method and apparatus for providing conditional access to media programs is disclosed. An embodiment of the method comprises the steps of generating a validation message in at least one of the receiver stations, the validation message comprising an answer to a validation query; transmitting the validation message directly from the receiver to the satellite on an always-on backchannel communications link; and receiving the media programs from the satellite only if the validation message matches an expected validation message.

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 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.
摘要:
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.

A method apparatus for providing conditional access to media programs is disclosed. The apparatus comprises a first conditional access module that is integral with a receiver; a second conditional access module that is removably communicatively coupleable with the receiver; and a conditional access kernel that controls the conditional access operations of the first conditional access module and the second conditional access module according to a control structure received by the receiver from a remote source.

摘要:
A method, apparatus, article of manufacture, and a memory structure for delivering purchase information comprising storing purchase information for a purchase of a user in a set top box. The set top box (STB) is configured to receive and display the broadcast signals through a tuner onto a display device. The STB establishes a connection to the Internet through a user initiated action (e.g., when the user accesses the Internet using the STB). A new transmission control/Internet protocol (TCP/IP) connection is obtained using the established user-initiated Internet connection without the user requesting the connection. A secure electronic connection is established with a server through the new TCP/IP connection. The purchase information is then transmitted from the STB through the secure electronic connection to the server.
