Abstract
A video decoding method includes decoding a bitstream including generating a quantized frequency transform block from the bitstream, reconstructing a residual block by inversely quantizing and inversely transforming the quantized frequency transform block, generating a prediction block by predicting a current block to be reconstructed, reconstructing the current block by adding the generated prediction block to the reconstructed residual block and performing a deblocking filtering with respect to a boundary between subblocks within a frame including the reconstructed current block, by allowing numbers of filtered pixels in a first block of the subblocks and a second block of the subblocks that engage in the filtering to be different depending on one or more predetermined criterion.
