A video decoding device comprising: de-multiplexing means for de-multiplexing a bitstream including PCM block size information; PCM block size determination means for determining a PCM block size for parsing a PCM header based on the PCM block size information de-multiplexed by the de-multiplexing means; PCM header parsing means for parsing the PCM header from the bitstream, in a block of the PCM block size determined by the PCM block size determination means; entropy decoding means for entropy-decoding transformed data of an image in the bitstream; inverse transform means for inverse-transforming the transformed data entropy-decoded by the entropy decoding means; PCM decoding means for decoding by PCM decoding PCM data of the image in the bitstream; and decoding control means for controlling the entropy decoding means and the PCM decoding means based on the PCM header parsed by the PCM header parsing means.
