摘要
A network of local area audience response systems is coupled together at a central audience response processing station by a satellite communication system for real time audience response analysis, nationally or internationally. Each local area station and each response unit may be identified and verified by allocation of specific time slots for response preferably synchronously related to a TV picture program transmission carrying the audience questions to be answered. Wireless transmission of the question and answer signals in digital format of beeps of a single frequency keeps transmission channels narrow. The system may be operated in conjunction with TV broadcasting or independently.
