Abstract:
1. An apparatus for generating analog audio signal from wireless radio frequency signal modulated with a first set of compressed digital audio data and a first set of associated index data, modulated with a second set of compressed digital audio data and a second set of associated index data, and modulated with a third set of compressed digital audio data, the apparatus comprising: a demodulator for demodulating the wireless radio frequency signal; memory for storing digital data, the stored digital data including the first and the second sets of compressed digital audio data and the first and the second sets of associated index data; a user interface allowing a user to select the stored digital data or the third set of compressed digital data; an output device; a controller for providing the first and the second sets of associated index data to be manifested on the output device if the user selects the stored data, the user interface further allowing the user to select the first or the second sets of compressed digital audio data in response to perceiving the first and the second sets of associated index data on the output device; a decompressor subsystem for decompressing the first set of compressed digital audio data to generate a first decompressed digital audio data if the user selects the first set of compressed digital audio data, decompressing the second set of compressed digital audio data to generate a second decompressed digital audio data if the user selects the second set of compressed digital audio data, and for decompressing the third set of compressed digital audio data to generate a third decompressed digital audio data if the user selects the third set of compressed digital audio data; and a digital to analog converter for generating the analog audio signal from the first decompressed digital audio data, the second decompressed digital audio data or the third decompressed digital audio data.
