Providing a reward as an incentive for a person to become an audience member of at least one program being performed by reproduction equipment. A programming signal used for broadcasting the program with a programming signal source is encoded with discrete code signals, such that a preset number of the code signals occur within a given period of time, to produce an output signal which is broadcast. The broadcast output signal is received, and the code signals therein are detected. The number of the code signals detected while the person is an audience member of the at least one program is compared with predetermined reward issuance criteria. A reward is issued when the reward issuance criteria are met by the number of detected code signals.
