Abstract
A technique for determining whether a program transmitted in a programming signal by a signal source was perceived by audience members within a specified time period. The programming signal is combined with a code signal to form a broadcast signal, wherein occurrence of the code signal corresponds to an occurrence of the program, and wherein the code identifies the program. The broadcast signal is monitored at a central processing facility and each received code is stored with an adjacent segment of the programming signal to create a master data base. Using a device located in the vicinity of an audience member, code signals corresponding to a program as it is being performed by program reproduction equipment and perceived by the audience member are monitored, and each code signal is stored with its said adjacent segment of the programming signal to create audience monitoring data. Based on the master data base and the audience monitoring data, determining whether the audience member perceived the program within a specified time period.
