摘要

PROBLEM TO BE SOLVED: To provide a method for decoding residual coefficients of a transform unit (TU) and a method for encoding residual coefficients from residual samples.SOLUTION: The method for encoding and decoding residual coefficients includes steps of: decoding two color difference residual coefficient arrays corresponding to each of 4x4 color difference blocks of a first color difference channel after four luminance residual coefficient arrays of a luminance channel is decoded; and decoding two color difference residual coefficient arrays corresponding to each of 4x4 color difference blocks of a second color difference channel after the two color difference residual coefficient arrays of the first color difference channel are decoded.SELECTED DRAWING: Figure 11
