Digital Image Decoder (DIGITAL IMAGE DECODER)

摘要

The present invention relates to a digital image decoding apparatus and, more particularly, to a digital image decoding apparatus which, when a motion vector of a current block is lost as a result of checking an image bitstream through an error detecting unit, The vector of the current block is reconstructed and compensated by the motion vector of the previous block among the previous frame image data stored in the frame memory through the motion compensation unit to compensate for the motion of the current block due to a channel error or the like, If the vector is lost, the image data of the current block is reconstructed and compensated by the motion vector of the previous block, so that deterioration of image quality caused by loss of the motion vector can be prevented.
