专利汇可以提供METHOD AND APPARATUS FOR DATA COMPRESSION WITH REDUCED DISTORTION专利检索,专利查询,专利分析的服务。并且Apparatus for compressing data is disclosed in which input data is compressed by a vector quantization process (22) and decoded by the vector quantization process (30). The input data and the decoded input data are compared and a different signal (dr) is produced. A portion of the difference signal (drs) is preferably losslessly compressed and transmitted with the vector quantized input signal to a decoder over a communication channel. The decoder (14) decodes the vector quantized portion of the signal (Ivq) and the compressed difference signal (dLR) for reconstructing the input signal with an error which is less than that which would result from uncompensated vector quantization.,下面是METHOD AND APPARATUS FOR DATA COMPRESSION WITH REDUCED DISTORTION专利的具体信息内容。
