发明名称 TRANSAKTIONSGEBUNDENES INTERAKTIVES SYSTEM
摘要 An interactive television system is disclosed where interactive information is inserted in the vertical blanking interval of a standard television signal (20) or some other appropriate medium. The signal is received and decoded by a settop device (28) which sends the decoded signal, via an infrared signal, to a handheld device (32). The system includes an interactive program authoring system (12), and programmer tables in the memory of the handheld device which store data for various interactive events. This system allows a viewer to enter and exit events at any time without having to wait for information to be downloaded and without losing scores. Furthermore, this system allows many interactive programs to run concurrently over extended periods of time while maintaining cumulative scores in the handheld device for each interactive program or series of programs. <IMAGE>
