METHOD AND APPARATUS FOR CODING/DECODING A VIDEO USING AN INTRA PREDICTION

摘要

A video decoding apparatus using an intra-prediction, includes: a decoder configured to reconstruct information on an intra-prediction mode of a current block to be decoded from a bitstream, and reconstruct transform block information from the bitstream and reconstruct transform coefficients corresponding to each of one or more transform blocks divided in a tree structure from the current block; an inverse transformer configured to reconstruct residual signals by inversely transforming the transform coefficients corresponding to each of the transform blocks; a predictor configured to generate predicted pixels based on the information on the intra-prediction mode; and an adder configured to add the residual signals to the predicted pixels.
