A system for identifying and responding to different broadcast programs

摘要

A receiver (30) responds to a variety of programs transmitted from different radio stations (22). Each radio station transmits both programs (23) and program codes (25) that describe associated programs. When a response button (32) on a radio receiver is pressed during a given program, the receiver automatically transmits a response code acknowledging the program. The radio listener is then relieved of the burden of having to manually dial a phone number and vocally acknowledging a response to a radio station operator.
