摘要: A sub-picture category (SP_CAT) is added to a unit header (SPUH) configuring unit, and flag “Raw” indicating pixel data run length compression/non-compression provided in the header. Original with 4-bit/1-pixel configuration subjected compression, if after compression exceeds size of original data, “Raw”=1 (non-compression) specified. If slightly compressed, “Raw”=0 (compression) specified, thereby enabling efficient recording information medium.
