Abstract
A method of communicating data in a satellite digital audio radio (SDAR) system includes transmitting two radio frequency digital signals to a SDAR receiver within a motor vehicle. The two signals include substantially identical information. Each signal includes universal data, and also group-specific data that may or may not be relevant to the particular receiver. The group-specific data is located in a predetermined time location within the signals. This method includes combining the group-specific data from one of the two signals with group-specific data from the other signal to create a group-specific output signal. Similarly, the universal data from one of the two signals is combined with universal data from the other signal to create a universal output signal.
