ABSTRACT:
A technique is used in a selective call communication system (100) and in a broadcast communication system (106) to provide additional information about a broadcast to a selective call device (111). A broadcast receiver (109) receives a broadcast that includes a prompt (220), such as a FLEX.TM. logo, and an information address signal (305), such as an inaudible portion of the sound portion of the broadcast. The prompt indicates that additional information is available in a message to be transmitted by the selective call communication system. The selective call device receives the information address signal when activated to do so in response to the prompt. The selective call device receives and decodes an information address from the information address signal and uses it to recover the message at a protocol position indicated by the information address. The additional information is then recovered from the message.
