Abstract
The process utilizing the inter mode with motion estimation with respect to a reference image and the intra mode, wherein: an exclusion zone which includes the macroblocks which lie even partially in the location of the imagette is defined in the image, the motion estimation of the macroblocks of the image not belonging to the exclusion zone cannot take account of an image block belonging to the exclusion zone in the reference image.
