Abstract:
The present technology relates to an encoder and an encoding method, a decoder and a decoding method, and a program by which encoding efficiency is able to be improved by constraining an appearance probability of a predetermined quantization value of an encoding target to 0 when encoding with a combination of Huffman encoding and multidimensional encoding is performed.

Claim (Index 1):
A decoder comprising:\n a reception unit configured to receive a plurality of codes including a plurality of variable length codes and constraint information, wherein the constraint information identifies whether an appearance probability of a predetermined quantization value is constrained or not; and a decoding unit configured to decode the plurality of variable length codes received from the reception unit by extracting a quantization value for each of the plurality of variable length codes from a constraint code book when the appearance probability of the predetermined quantization value is constrained and from an unconstraint code book when the appearance probability of the predetermined quantization value is not constrained, wherein the appearance probability of the predetermined quantization value is constrained to 0 when a combination of Huffman decoding and multidimensional decoding is performed, and wherein the reception unit and the decoding unit are each implemented via at least one processor.
