A device (100) that enables generation of a response to a data stream sent in combination with a broadcast signal (162) is described. The device comprises a receiver circuit (100, 200, 300) that detects the broadcast signal (162) and extracts data that enables unique identification of a specific occurrence of a broadcast segment from at least a portion of the data stream; memory (114, 220, 320) for storing at least the data that enables the unique identification of the specific occurrence of the broadcast segment; a display (110, 210, 380) for displaying information corresponding at least in part to the broadcast segment; an input control (116,112) that enables the selection of at least part of the displayed information and further enables the generation of the response; and a transmitter (156, 218, 318) that transmits a response packet corresponding to the response generated using the input control, the response packet including at least the data that enables unique identification of the specific occurrence of the broadcast segment of the selected part of the displayed information, to a response authentication system. |
