Abstract (en)
[origin: WO2010043811A1] The invention relates to a method of coding an image sequence, comprising a step of splitting (11) a current image into blocks of standard size, termed macroblocks. According to the invention, the method comprises, for at least one current macroblock of said current image, the following steps: - construction (12) of at least one block of greater size than said current macroblock, termed a large block, comprising said current macroblock and at least one neighbour macroblock in said current image, taking account of characteristics of said current image; - coding (13) of said large block, delivering base coding information, making it possible to reconstruct a base layer of said current image, and for at least one large block, determination (14) of enhancement information associated with at least one macroblock present in said large block.
