<p>A system (10) allows a user to obtain additional data related to information being broadcast via a given media. The entire system (10) includes a data distribution station (11) that emits a main signal portion (18) and a secondary signal portion (20) having a signature corresponding to the main signal portion (18). A receiver system (12) receives the main signal portion (18) and converts it to a form perceptible by an individual. It also receives the secondary signal portion (20), which would typically represent a telephone number. The user can selectively transmit data carried by the secondary signal portion (20) to a specific site (15). This specific (15) site includes a data relay system (14) able to receive the transmitted secondary signal portion (20) and in response transmit specific data back to the receiver system (12) for storage and use by the individual.</p> |
