Abstract
A method and apparatus are provided for identifying predetermined individual members of a television viewing audience/marketing group in a plurality of monitored areas. A plurality of predetermined identification signals are stored each corresponding to one of the predetermined individual members. A transmitter device for transmitting a unique predetermined identification signal is associated with each of the predetermined individual members. A receiver device in each of the plurality of monitored areas receives the transmitted predetermined identification signals and applies the received signals to an associated memory device used for storing the received individual member signals. A central processor periodically retrieves the stored individual member signals from each memory device. The received predetermined identification signals are compared with the stored predetermined identification signals to identify the predetermined individual members and further processed to correlate each of the identified individual members at different ones of the monitored areas.
