Abstract
A video decoding apparatus using an intra-prediction, performs a method including: reconstructing information on an intra-prediction mode of a current block to be decoded from a bitstream, wherein the current block is a square block; reconstructing transform block information from the bitstream and reconstructing transform coefficients corresponding to each of one or more transform blocks divided in a quad tree structure from the current block; and reconstructing the current block based on the information on the intra-prediction mode and the reconstructed transform coefficients of the transform blocks.
