<p>The field of the invention is that of the coding of auxiliary data for the reconstruction of undersampled animated electronic images, particularly for TVHD transmission over MAC channel. …<??>The objective is to furnish a rate-regulating method allowing auxiliary data coded at variable rate of the type using a compression procedure comprising a step for selection, for each elementary image block, of an optimal processing from several concurrent compression processings carried out in parallel, the processings comprising in particular at least one low rate-consuming processing, to be made to travel through a fixed rate channel. …<??>According to the invention, the method is characterised in that the choice of compulsory processing is forced from one of the low rate-consuming processings (11), during the said step for selection of an optimal processing, when the rate (13) of the said auxiliary data approaches or exceeds the rate (10) permitted per unit of transmission. …<IMAGE>… </p> |
