摘要: A video coding or decoding method operable to generate blocks of quantised spatial frequency data by quantising the according a selected quantisation step size and matrix modifying for use at different respective block positions within an ordered samples, being with respect least two chrominance subsampling formats; comprises one formats, defining more matrices as predetermined modifications reference defined formats.
