Claim One:
1. A method for processing a signal, comprising: compressing, decompressing, or both compressing and decompressing, the signal in a processor, wherein the compressing step comprises processing the signal in the processor to generate encoded data, and the decompressing step comprises processing the encoded data in the processor to generate a reconstructed signal approximating the signal, wherein: the encoded data comprises three or more distinct data layers, including one base layer, one or more common layers, and one or more enhancement layers; the reconstructed signal is a base level reconstructed signal or an enhancement level reconstructed signal; the enhancement level reconstructed signal is of higher quality than the base level reconstructed signal; the base level reconstructed signal is generated only from the base layer and one or more of the common layers; and the enhancement level reconstructed signal is generated only from one of the enhancement layers and one or more of the common layers.
