ABSTRACT:
The invention lies within the area of image compression coding, in particular of MPEG type, which uses recoding help data. The invention affords a solution for reusing the help data selectively. To this end, the invention adjoins an electronic signature representative of the constraints of the coder. Thus, it becomes possible to determine whether the help data are reusable or not for a subsequent coding using other constraints.
