Abstract: Monitoring an audience member tuned to a broadcast program. A portable audience monitoring unit is adapted to be worn by the audience member, and it detects a signal corresponding to the broadcast program to which the audience member is tuned. The detected signal is stored in the audience monitoring unit, and then the detected signal stored in the audience monitoring unit is outputted. The outputted detected signal is communicated to a central processing station by a communication means for transmitting the outputted detected signal with Cellular Digital Packet Data (CDPD) technology. In another embodiment, the communication means utilizes a ReFLEX protocol.

Abstract: A method and apparatus for, interactively with a broadcast program that is being performed, enabling access to supplementary materials related to the program from a broadcast signal that is a combination of a programming signal and a supplementary materials signal. The broadcast output signal is received at a location of an audience. The programming signal of the received output signal is performed for the audience, with reproduction equipment. A signal related to the supplementary material signal is extracted from the received broadcast signal. Access to the supplementary material corresponding to the supplementary material signal is enabled in response to an interactive control signal actuated by a member of the audience tuned to the programming signal being performed, and based on the extracted signal.
