Abstract

A system is provided that includes a captioning computer system, a caption caster controller, a caption caster system, and a portable receiver system having an eye piece. The captioning computer system generates a caption stream associated with a radio program and transmits the caption stream to the controller. The controller identifies the program associated with the received caption stream, identifies the caption caster system as being located in the coverage area of the identified program, and distributes the received caption stream to the caption caster system based on its location and the radio program'"'"'s coverage area. The caption caster system sends the caption stream received from the controller to the portable receiver system via a radio station communication channel, to which each portable receiver system may be selectively tuned such that the captions extracted from the stream may be displayed on the eye piece of the portable receiver system.
