摘要
An audience surveying technique for identifying individual members of an audience listening to and/or watching a program performed from a programming signal source. A stationary apparatus is operatively arranged at a reception location with a plurality of portable devices designed to be worn by the audience members. The stationary apparatus detects and stores a surveying code transmitted with the program, and it also periodically emits a trigger signal which causes the portable devices to respond by emitting a unique identification signal pre-stored in each one. The stationary apparatus also detects and store the identification signals. By associating the detected surveying code with the detected identification signals it is possible to quickly, accurately and reliably identify the individual audience members tuned to a particular program.
