  • Transaction based interactive television system
    Patent number: 5526035
    Abstract: An interactive television system where interactive information is inserted in the vertical blanking interval of a standard television signal. The signal is received and decoded by a settop decoder which sends the decoded signal via an infrared signal to a handheld device. The viewer using the handheld device can interact with a game, sports, or educational event or other presentation on the television. The system includes a proprietary high level command language and programmer (PIU) tables which are maintained in the memory of the handheld device. The PIU tables store the transactions of the various events presented on the television. The transactions are sent from the insertion system to the decoder throughout the broadcast of the television program.

  • Interactive television security through transaction time stamping
    Patent number: 5519433
    Abstract: A system for providing security on an interactive television system. Two sets of interactive data, with time stamps, are separately sent to a remote location. At the remote location, the time stamps are checked against a remote clock, a time difference being noted for both sets of data. The two time differences are compared to determine if one set of data has been delayed as compared to the other. Non-delayed data can be used to update a game score for an interactive game. After the game is completed, the remote clock is compared to a central clock. The difference between the two clocks are compared to the time difference for non-delayed data to determine whether the entire aggregate of interactive data was delayed.
