Document Type and Number:
WIPO Patent Application WO/2021/256082
Kind Code:
A1
Abstract:
The present invention reduces the number of encoded bits in vector quantization. This encoding device is provided with: a quantizing circuit which generates a quantization parameter including first information relating to a vector quantization codebook, and second information relating to code vectors included in the codebook; and a control circuit which employs a second number of bits based on the difference between a first number of bits available for encoding of a sub-vector in the vector quantization, and the number of bits in the sub-vector quantization parameter, to control encoding of the first information with respect to the sub-vector.
