A system, method, and electronic chip for compressing a digital data signal while maintaining a quality level is disclosed. A signal is received that is representative of a quality level. The signal may be received into a computer system or into an electronic chip, such as an application specific integrated circuit or an electronic chip operating with a computer system. A digital data signal, which may be a digital image stream is decorrelated based in part on the received quality level. The decorrelated digital data signal is quantified according to frequency so as to provide equal resolution across all frequencies. The quantified digital data signal is then entropy encoded. The digital data signal is thereby compressed. Upon decompression, the uncompressed data maintains the desired quality level over all values. If the values are color components within a digital image stream, the color components will have the desired S/N ratio.
