Claim Text:
1. A video decoding apparatus comprising: a decoder configured to an inverse transformer configured to reconstruct a residual block corresponding to each of the transform blocks by inversely transforming the transform blocks in units of the size of each of the transform blocks; a predictor configured to generate a predicted block by using an intra-prediction; an adder configured to reconstruct the current block by adding the residual block to the predicted block; and a filter configured to identify transform boundaries between the transform blocks in the reconstructed current block by using the size of each of the transform blocks determined based on both the size of the current block and the information on the transform type, and then perform deblocking-filtering on at least part of the transform boundaries, wherein the decoder is configured to identify whether the current block is divided into a plurality of blocks and then recursively identify whether each of divided blocks is further divided, based on the transform information, to thereby identify blocks which are not further divided as the transform blocks, wherein the decoder is configured to reconstruct each of the transform blocks by scanning transform coefficients corresponding to each of the transform blocks according to a scanning pattern corresponding to each of the transform blocks, and wherein the scanning pattern is determined based on the size of each of the transform blocks.
