Abstract
A coding method for coding a picture in a moving picture with a processor configured to code, on a block-by-basis, each picture in the moving picture, to generate a coded stream. The processor transforms each picture into coefficients representing spatial frequency components and quantizes the coefficients with a quantization matrix. Identification information identifying the quantization matrix is provided in the coded stream in predetermined units to reduce the amount of data to be coded. The processor is configured to use a coded quantization matrix for a chroma component rather than a default quantization matrix.
