1. Method of coding a video image sequence in coefficients of frequency sub-bands with different spatial resolutions, the method comprising forming at least one data stream having at least one restitution level comprising coefficients of frequency sub-bands having a spatial resolution equal to a spatial resolution of the restitution level, inserting, in at least one of the restitution levels, coefficients of frequency sub-bands having a spatial resolution higher than the spatial resolution or resolutions of the at least one restitution level.
