Zusammenfassung: | PROBLEM TO BE SOLVED: To provide information concerning broadcast or recorded segments to which audience members have been exposed, to detect which segments were actually broadcast at a given time period, to provide media exposure records for audience members to a centralized facility, and to receive information from a centralized facility, via an encoded transmission hidden within a pre-existing transmission channel. SOLUTION: A personal monitor, worn by the audience member, monitors reproduced broadcast or recorded audio signals, and generates monitored audio signal information including source identification information. Next, the personal monitor transmits the monitored audio signal information, including the source identification information to a wireless receiver via wireless transmission. Then, the wireless receiver transmits the source identification information to a base station located at the home of the audience member, and the base station transfers information that identifies the source to a centralized data processing facility.
