The method comprising: a step for partitioning the image into regions, a region being made up of a set of consecutive or non-consecutive blocks, according to the television scanning order of the image, an inter- or intra-block coding step, the blocks being coded by region according to an ordering of the regions, and, for a region, according to the order of succession of the blocks that make up the region, a coded block error correction step, is characterized in that, a step for analysing the field of movement is carried out to calculate a “lifespan” parameter assigned to a block and corresponding to its probability of existence in subsequent images, according to the movement vector associated with this block, the partitioning step is performed taking into account the value of this parameter to define and order the regions of the image from most important to least important, the error correction step uses a more effective error correction algorithm for the coded data corresponding to the first regions than for the data corresponding to the latter regions.
