Abstract (en)
[origin: WO2012120217A1] The invention relates to a method of coding at least one image comprising the steps of splitting the image into a plurality of blocks (MB), of grouping said blocks into a predetermined number of subsets of blocks, of coding each of said subsets of blocks in parallel, the blocks of a subset considered being coded according to a predetermined sequential order of traversal. The coding step comprises, for a current block of a subset considered, the sub-step (C341) of predictive coding of said current block with respect to at least one previously coded and decoded block, and the sub-step (C345) of entropy coding of said current block on the basis of at least one probability of appearance of a symbol. In the case where the current block is the first block to be coded of a subset considered, said probability of appearance of a symbol is that which was calculated for a predetermined coded and decoded block of at least one other subset. In the case where the current block is a block of said subset considered, other than said first block of the latter, said probability of appearance of a symbol is that which was calculated for at least one coded and decoded block belonging to said same subset.
