A system and method for broadcast response generally employing RDS, DARC, or similar technology is provided, including a method for responding to a broadcast comprising extracting an event identifier from a broadcast signal; detecting a response by a user to the broadcast signal; polling a communications device to determine a user identifier; and communicating the event identifier and the user identifier when the user response is detected.

Systems and methods are provided for broadcasting a signal. A multiplexer combines a first signal from a first signal source and a second signal from a second signal source as a time divisional multiplexed signal and provides a timing signal, distinct from the time division multiplexed signal, that indicates, for a given time, from which of the first and the second signal source a corresponding portion of the time divisional multiplexed signal originated. A signal conditioning component receives each of the time divisional multiplexed signal and the timing signal and alters the time division multiplexed signal in a manner that prepares the signal for broadcast. The signal conditioning component dynamically alters its behavior according to the timing signal. An antenna transmits the time division multiplexed signal.
