Zusammenfassung:An encoding device comprising: a quantization circuit that generates a quantization parameter that includes information about a vector quantization codebook; and a control circuit that sets the number of available bits according to conditions for encoding based on the difference between the number of bits available for encoding of the target sub-vector and the number of bits for the quantization parameter of the target sub-vector.
