    Abstract: PROBLEM TO BE SOLVED: To provide a moving picture decoding method capable of reducing the amount of encoding to efficiently perform encoding and decoding. SOLUTION: The method for decoding moving pictures, includes the steps of: holding step for acquiring a second quantization matrix and a matrix ID from a code train to hold them; step for extracting a matrix ID, which accompanies picture encoded data and specifies a quantization matrix used when the current picture is encoded, from the code train; and quantization matrix specifying step for specifying a quantization matrix corresponding to the extracted matrix ID. A picture is composed of a luminance component and two color difference components. In the quantization matrix specifying step, when a quantization matrix for a color difference component does not exist in a quantization matrix specified by the matrix ID, a quantization matrix for another color difference component is specified as a quantization matrix used for color difference component.
