ABSTRACT:
An information processing method used for compressing or decoding picture data wherein, in securing an area in which to store restored picture data, pre-set processing can be performed speedily without producing caching errors. Storage sites on a data memory are allocated to luminance signals and to associated chroma signals so that the luminance signals and the associated chroma signals will be copied in different locations in a data cache. The luminance signals and the associated chroma signals so allocated are stored in the data memory. For decoding, plural picture data related with one another are allocated to different locations in the data memory so that the picture data will be copied indifferent addresses in the data memory.
