Abstract
A video decoding apparatus includes a decoder to decode division information related to dividing a current block into subblocks, and reconstruct transform coefficients of each of the subblocks identified by the division information, and thereby generate transformed residual subblocks; an inverse transformer to inverse-transform each of the transformed residual subblocks, and thereby generate residual subblocks; a predictor to generate predicted subblocks by intra-predicting each of the subblocks; an adder to reconstruct the current block by adding the predicted subblocks to the residual subblocks corresponding thereto; and a first filter to perform deblocking-filtering on boundaries between the subblocks in a reconstructed picture including the reconstructed current block.
