Abstract
A method of transmitting digital audio broadcasting signals comprises the steps of generating a plurality of output frames of information to be transmitted, wherein each of the output frames includes a plurality of blocks of data and each of the output frames is synchronized with an absolute time reference, and transmitting the output frames to a plurality of receivers. The information to be transmitted can identify the location of a transmitter. Transmitters that broadcast in accordance with the method and receivers that receive the transmitted signal are also disclosed. A method is also provided for receiving digital audio broadcasting signals comprising the steps of receiving a digital audio broadcasting signal comprising a plurality of output frames of information to be transmitted, wherein each of the output frames includes a plurality of blocks of data and each of the output frames is synchronized with an absolute time reference, and determining the start of each output frame relative to an absolute time reference.
