Abstract
A quantization device includes: a trellis-structured vector quantizer which quantizes a first error vector between an N-dimensional (here, 'N' is two or more) subvector and a first predictive vector; and an inter-frame predictor which generates a first predictive vector from the quantized N-dimensional subvector, wherein the inter-frame predictor uses a predictive coefficient comprising an N×N matrix and performs an inter-frame prediction using the quantized N-dimensional subvector of a previous stage.
