Abstract
An audio and data interactive system and method includes at least one base unit and at least one remote unit. The at least one base unit has a first microprocessor-based control and the at least one student unit has a second microprocessor-based control, a speaker system and a wireless transceiver. The first control combines digital data with at least one audio signal within the human hearing range and supplies the combined digital data and audio signal to the first transceiver. The second control separates the combined digital data and audio signal from the second transceiver into the digital data in the audio signal. The second control supplies the audio signal to the speaker system and causes the second wireless transceiver to transmit in response to the digital data.
