Abstract
A broadcast station transmits radio frequency signals containing on-demand, main program, and index materials to a plurality of receivers. The receivers contain means for separating the index material from the other materials. The receivers contain a signal switch for selecting one of the materials. A user can decide to listen to any of these materials by pressing a button. The receivers contain control logic that can direct the signal switch to select the desired material. After the on-demand material is played, the signal switch automatically switches back to the main program material.
