Abstract

La présente invention concerne un procédé de traitement vidéo comprenant la mise en œuvre, pour une conversion entre un bloc vidéo actuel d'une image actuelle appartenant à des données multimédias visuelles et une représentation de flux binaire des données multimédias visuelles, d'un tampon comprenant des échantillons de référence de l'image actuelle pour une dérivation de bloc de prédiction du bloc vidéo actuel. Un ou plusieurs échantillons de référence dans le tampon qui sont marqués comme indisponibles pour la dérivation ont des valeurs qui ne sont pas comprises dans une plage de valeurs de pixel.
