Abstract
A receiver contains a demodulator system that can extract digital data from wireless radio frequency signal. The digital data contains two sets of compressed digital audio data corresponding to two audio programs. The receiver also contains two decompressors. If a user selects a first audio program, a first compressor is used to decompress a first set of compressed digital audio data. If a user selects a second audio program, a second decompressor is used to decompress a second set of compressed digital audio data. The wireless radio frequency signal can be transmitted using a transmitter.
