Abstract (en)
[origin: WO03087961A1] A television entertainment system (Fig. 2) has two-way communication capability with a hand-held remote device (20) accessing an external information source (32). It includes a television receiver (42) adapted to receive television programming content, and a television set top box (52) adapted to receive program related information over a broadcast channel and transmit the program related information to the hand-held remote device. The hand-held remote device (20) is adapted to visually render information received over a broadcast channel and synchronize (34) delivery of the program related information with delivery of related information from the external information source (32).
