1. A method of coding at least one image comprising the steps of: cutting of the image into a plurality of blocks, grouping of blocks into a predetermined number of subsets of blocks, coding in parallel of each of said subsets of blocks, the blocks of a subset considered being coded according to a predetermined sequential order of traversal, said coding step comprising, for a current block of a subset considered, the sub-steps of: predictive coding of said current block with respect to at least one previously coded and decoded block, entropy coding of said current block on the basis of at least one probability of symbol occurrence, wherein: in the case where the current block is the first block to be coded of a subset considered, said probability of symbol occurrence is that which was calculated for a coded and decoded predetermined 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, said probability of symbol occurrence is that which was calculated for at least one coded and decoded block belonging to said same subset.
