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.
