Abstract
Apparatus for compressing data is disclosed in which input data is compressed by a vector quantization process and decoded by the vector quantization process. The input data and the decoded input data are compared and a difference signal as produced. A portion of the difference signal is preferably losslessly compressed and transmitted with the vector quantized input signal to a decoder over a communication channel. The decoder decodes the vector quantized portion of the signal and the compressed difference signal for reconstructing the input signal with an error which is less than that which would result from uncompensated vector quantization.
