In the quantizer, a classifier (101) selects a classification code vector indicating the type of feature having the correlation with the vector to be quantized from a plurality of classification code vectors. A switch (102) selects a first codebook corresponding to the type from a plurality of first codebooks. An error minimizing section (105) selects a first code vector closest to the vector to be quantized from a plurality of first code vectors constituting the selected first codebook. An additivity factor determining section (106) selects an additivity factor vector corresponding to the type from a plurality of additivity factor vectors.

摘要： A coding device is provided with features in which optimum coding in a higher layer is flexibly carried out based on a coding result of a lower layer and a quality audio signal in limited circumstances is served to users. In this coding device, a basic layer coding unit codes an input signal to generate a basic layer information source code and outputs a linear prediction coefficient (LPC) and a quantum LPC, which are parameters calculated at coding, to an expanded layer control unit. A basic layer decoding unit decodes the basic layer information source code. An adding unit reverses a polarity of a basic layer decoded signal, adds the same to the input signal, and calculates a difference signal. The expanded layer control unit generates expanded layer mode information indicative of a coding mode in an expanded layer based on the LPC and the quantum LPC. An expanded layer coding unit codes the difference signal obtained from the adding unit under control of the expanded layer control unit.

摘要： To implement scalable coding, a base layer coding section encodes an input signal to obtain base layer coded information, which is decoded by a base layer decoding section to obtain a base layer decoded signal and long term prediction information (pitch lag). An adding section inverts the polarity of the base layer decoded signal to add to the input signal, and obtains a residual signal. An enhancement layer coding section encodes a long term prediction coefficient calculated using the long term prediction information and the residual signal to obtain enhancement layer coded information. Also using the long term prediction information, an enhancement layer decoding section decodes the enhancement layer coded information to obtain an enhancement layer decoded signal. An adding section adds the base layer decoded signal and enhancement layer decoded signal to obtain a speech/sound signal.
