Abstract

L'invention concerne un procédé de codage vidéo au cours duquel: - a) on code des images successives (F) d'une séquence vidéo pour générer des paramètres de codage, - b) on inclut les paramètres de codage dans un flux de sortie (Φ) à transmettre à une station (B) comportant un décodeur (2), - c) on reçoit de ladite station des informations de retour sur la restitution des images de la séquence vidéo par le décodeur, - d) on analyse les informations de retour pour : • d1 ) identifier, parmi les images restituées, si au moins une image comprend au moins une partie qui a été perdue au niveau du décodeur, • d2) identifier, parmi les images codées s'étant succédées entre, d'une part, ladite image restituée et, d'autre part, une image courante à coder, au moins une partie d'image qui se réfère à ladite partie perdue identifiée à l'étape d1 ), - e) on code ladite image courante de la séquence vidéo selon un mode de codage qui est fonction de l'identification ou de la non identification d'au moins une partie perdue telle qu'effectuée à l'étape d).
