Symbol-display system

This invention discloses an anti-piracy system including video representation signature apparatus for computing a forbidden signature of a forbidden video representation, communication apparatus for communicating the forbidden signature to a playing device, and a playing device adapted to receive and play back a recorded video representation, the playing device including reception apparatus for receiving the forbidden signature communicated by the communication apparatus, recorded video representation signature apparatus for computing a signature of the recorded video representation, and playback control apparatus operative to prevent playback of the recorded video representation if the computed signature of the recorded video representation matches the forbidden signature communicated to the playing device

System for preventing playback of unauthorized digital video recordings

A subscriber unit in a television system including an integrated receiver and decoder (IRD) including a first smart card reader which is operative to accept a first smart card, and a remote control including a second smart card reader which is operative to accept a second smart card. The first smart card and the second smart card, when inserted in the corresponding first and second smart card readers respectively, are operative to communicate with each other in wireless communication over a wireless communication link to control access to services.

Distributed IRD system

A pay television system including a pay television network and a subscriber unit which receives pay television transmissions via the pay television network and displays the pay television transmissions on televisions coupled thereto. The subscriber unit includes at least two pay television decoders, wherein a first decoder includes a first card reader and a second decoder includes a second card reader. The system also includes a first smart card which is operative, upon insertion in a first slot in the first card reader, to activate decoding of the pay television transmissions in the first decoder and a second smart card which is operative, upon insertion in a second slot in the second card reader, to activate decoding of the pay television transmissions in the second decoder. The second smart card deactivates in accordance with predetermined criteria and reactivates upon insertion in the first slot in the first card reader after removal of the first smart card from the first card reader.

Smart card chaining in pay television systems

A system for producing an output scrambled digital data stream from an input scrambled digital data stream. The input scrambled digital data stream includes a plurality of control messages (ECMs), each ECM including coded information for generating a control word (CW) associated with the ECM and being encoded using an ECM key. The input scrambled digital data stream also includes a plurality of segments of scrambled digital data, each segment of scrambled digital data being associated with one of the plurality of ECMs and being scrambled using the CW associated with the ECM. A method for producing the output scrambled digital data stream includes replacing each of the plurality of ECMs with a corresponding transformed ECM (TECM), each corresponding TECM comprising coded information for generating the CW associated with the corresponding ECM and being encoded using a TECM key, thus producing the output scrambled digital data stream, wherein the ECM key is replaced with a new ECM key at an ECM key change time, and the TECM key is not replaced at the ECM key change time.

Digital recording protection system

This invention discloses a vehicle theft prevention system which is operative to communicate with a central control station that transmits control signals to the vehicle, the system including an antenna, a receiving unit coupled to the antenna and operative to receive, via the antenna, the control signals transmitted by the central control station, and a processor which is operative to apply interference to operation of at least one critical engine component in the vehicle after an interruption in reception of the control signals at the receiving unit.
