Abstract

A digital broadcast system, comprising a master radio broadcast station located at a main predetermined location for formatting and broadcasting a plurality of channels of digitized program data in a spread spectrum, time and frequency hopping waveform to remote mobile and stationary receivers. A plurality of relatively low power range extension radio broadcast stations are provided, each said range extension station being located in selected areas and, each range extension station being adapted to receive and store one or more channels of program information from the master station. A separate program distribution system coupling the received and store of each range extension radio broadcast station with the master radio broadcast station, said separate distribution system, including, for each range extension station at least one path selected form satellite, microwave, fiber-optic, coaxial cable and telephone paths, for coupling one or more channels of program information to each range extension station. The channels of digital data re-broadcast from each of the range extension radio broadcast stations is synchronized with broadcasts from the master radio broadcast station such that a mobile receiver traveling between edges of reception of two or more low power range extension radio broadcast stations does not evidence interference therebetween.
