Category (FI): H04N19/13,H04N19/70,H04N19/593
Stage: PROBLEM TO BE SOLVED: To provide an intra-frame prediction mode mapping method for improving decoding efficiency.SOLUTION: A decoding method decodes a syntax element of information on a candidate intra prediction mode when one of the candidate intra prediction modes for the current block is the same as the intra prediction mode, and decodes syntax elements of the remaining intra prediction modes when they are not the same. A prediction block is generated on the basis of the intra prediction mode of the current block, and a reconstructed block is generated on the basis of the prediction block. The remaining intra prediction mode information has a shorter codeword length of an index than the candidate intra prediction mode. The syntax element of the remaining intra prediction mode information is a value coded using a fixed 5 bits.SELECTED DRAWING: None (Grant)
