ABSTRACT:
A method and system for synchronizing display of data relating to a predetermined application between an interactive terminal and at least one mobile interface device having a display. The at least one mobile interface device receives a user input signal and transmits the user input signal for synchronization with the interactive terminal. A set-top transceiver device is operatively coupled to the interactive terminal and receives the user input signal from the at least one mobile interface device. The set-top transceiver device also transmits a synchronization signal to the at least one mobile interface device and the interactive terminal. A central processing unit having a database is operatively coupled to the set-top transceiver device for receiving and processing the user input signal based on the database to obtain the synchronization signal for receipt by the set-top transceiver device. The synchronization signal includes a first display control signal for controlling the display of the at least one mobile interface device and a second display control signal for controlling the display of the interactive terminal.
