Patent ID: 7856217

Claim:
An apparatus for generating analog audio signal, comprising: a demodulator for retrieving digital data from wireless radio frequency signal, the digital data comprising a first set of compressed digital audio data associated with a first audio program and a second set of compressed digital audio data associated with a second audio program, the first set of compressed digital audio data having been compressed outside of the apparatus from a first set of digital audio data, the second set of compressed digital audio data having been compressed outside of the apparatus from a second set of digital audio data; a first decompressor comprising a first digital audio decompression algorithm; a second decompressor comprising a second digital audio decompression algorithm; a user interface allowing a user to select the first or the second audio program; and a control subsystem for applying the first decompressor to decompress the first set of compressed digital audio data if the user selects the first audio program and applying the second decompressor to decompress the second set of compressed digital audio data if the user selects the second audio program.
