ABSTRACT:
A vector quantizer for quantizing the vector of image and audio information, the vector quantizer being capable of efficiently encoding a compensation predictive error signal at a reduced bit rate by performing adaptive vector quantization after judging the significance of the compensation predictive error signal in blocks, and capable of movement compensation inter-frame vector encoding in which variable-length encoding of movement vector is facilitated and information production control is achieved easily.
