Abstract
A video encoding method includes: determining a size of a current block to be encoded and encoding information for indicating the size of the current block; encoding division information related to dividing the current block into one or more subblocks; predicting a subblock divided from the current block by using an intra prediction mode corresponding to the subblock; generating a residual block by subtracting the predicted block from the subblock; transforming the residual subblock by using a transform size identical to a size of the subblock; and encoding information on transform coefficients of the transformed residual subblock.
