The process for coding a mosaic of images giving a stream of coded data the mosaic being composed of subimages, the subimages being composed of image elements, resynchronization markers in the stream allowing resynchronization of the data at reception level, wherein the subimages are placed under one another in the image to be coded so as to give a mosaic, the mosaic is coded element by element according to a TV-type scan so as to provide data of the stream, the first element of each subimage being identified, and a resynchronization marker is placed in the stream, before each first element of a subimage, so as to identify the data relating to the subimage.
