CA 2124000
A transaction based interactive televi- ion system (20) includes an insertion system (22) for inserting in a preferred embodiment coded interactive information in the vertical blanking interval of a standard television sig- nal. The signal is received and decoded by a decoded system (24) which includes a settop decoder (30) which sends an infrared signal to a handheld device (28). The viewer using the handheld device (28) can interact with a game, sports, or educational or event or other presentation on television. The system includes proprietary high level command language and a proprietary set of PIU tables which are handheld in non-volatile memo- ry (74) of the handheld device (28). The PIU tables store the transaction of the various events presented on the television. The PIU tables allow the various events to be broken down into a number of transactions. Thus, for a sports event with interleaved commercials, a number of PIU tables would be used to store a collection of transactions used for the main event and additional PIU tables are used for storing transactions for each of the various interleaved commercials.
