发明名称 TRANSACTION BASED INTERACTIVE TELEVISION SYSTEM
摘要 A transaction based interactive television 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 signal. 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 maintained in non-volatile memory (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.
