摘要

The invention refers to a process of coding at least one image divided into sections,by applying the --prediction (C2) stages of the data of a current section in relation to at least one already encoded reference section,then decoded,by providing a predicted section (C6) of a set of residual data by comparing the relevant data with the current section and the section that has foreseen,that the remaining data are linked to different digital information respectively,intended to undergo an entropic coding. Before the processing stage of a signal containing that coded information,the following steps are carried out:from that set of identified residues,a subset containing residual data,capable of being modified,Calculation (C8) of the value of a function representative of the residual data of that identified subset,Comparison (C9) of this estimated value with at least one value of one of these digital information-depending on the outcome of that comparison,modification (C10) or not at least one of the remaining data of that subset,-in the event of modification,Enteropium coding (C20) of that minimum of one modified residual data.
