Abstract:
1. A method of generating a reconstructed block, comprising: deriving an intra prediction mode of a prediction unit using three intra prediction modes which are determined by left and above intra prediction modes; determining a size of a current block using transform size information; generating a prediction block of the current block according to the intra prediction mode; generating a residual block of the current block according to the intra prediction mode and the size of the current block; and generating a reconstructed block of the current block using the prediction block and the residual block, wherein the size of the current block is equal to or smaller than a size of the prediction unit, and the sizes of the prediction block, the residual block and the reconstructed block are equal to a size of a transform unit, and the transform size information includes one or more split_tu_flags, and wherein generating the residual block of the current block comprises:
