1. A method of scalable coding of moving images using at least one reference image for at least one image to code, that comprises, at least on passing, for a so-called “current” image, from an initial quality level to an intended quality level different from the initial quality level: a step ( 705 ) of coding the current image as far as the intended quality level to provide a coded current image, a step ( 710 ) of reconstructing the current image at the intended quality level by using the coded current image and at least one reference image for the intended quality level, to provide a reconstructed current image of intended quality level, a step ( 715 ) of obtaining at least one reference image of the current image at the initial quality level, to provide a prediction image for the initial quality level, a step ( 720 , 725 ) of determining a differential texture refinement depending on the prediction image for the initial quality level and on the reconstructed current image of intended quality level and a step( 730 ) of coding the differential texture refinement.
