ABSTRACT:
A receiver contains a demodulator system that can extract digital data from wireless radio frequency signal. The digital data contains three sets of compressed digital audio data. Two sets of compressed digital audio data are delivered in a first frequency band and the other set in a second frequency band. The set in the second frequency band and one of the sets in the first frequency band are stored in a memory system and the remaining set is not stored in the memory system. A user can select one of these three sets of compressed digital audio data for decompression and then converted to analog audio signal.
