The invention relates to a video decording device, and the device comprises an extraction device used for extracting PCM block size information from a bit stream; a PCM block size determination device used for determining PCM block size minimum value for analyzing PCM head based on the PCM block size information; a PCM head analyzer used for that if the block type is as an intra-frame predicdion and the size of the block is equal to or greater than the minimum value of the PCM block size, the PCM head is analyzed by the bit stream in the block; an entropy decoding device used for analyzing changed data of an image in the bit stream; a PCM decoding device used for decoding the PCM data of the image in the bit stream through PCM decoding; and a decoding control device used for controllling the entropy decoding device and the PCM decoding device based on the PCM head.
