METHOD AND APPARATUS FOR ENCODING AND DECODING

摘要

PURPOSE: A video decoding method and a computer-readable recording medium thereof are provided to improve encoding efficiency. CONSTITUTION: A prediction mode specify unit determines an intra prediction mode for a current block (S1220). A scanning unit performs scanning of a residual signal from the intra prediction of the current block (S1240). The scanning unit determines a scanning type of the residual signal of a luminance signal and a chrominance signal of the current block based on the intra prediction mode for a luminance sample of the current block.
