Abstract

Procédé de protection d'un flux vidéo compressé pouvant être décomposé en un premier plan composé d'objets d'un premier type et d'un second plan composé d'objets d'un second type contre les erreurs lors de la transmission de ce flux sur un lien non fiable, caractérisé en ce qu'il comporte au moins les étapes suivantes : a) analyser le flux dans le domaine compressé (1 1, 12) afin de définir différentes zones de l'image dans lesquelles de la redondance va être ajoutée, les vecteurs estimations de mouvement et les coefficients transformés obtenus dans le domaine compressé sont transmis à l'étape d'ajout de redondance, b) ajouter de la redondance (13a, 13b, 14) aux objets desdites zones déterminées à l'étape précédente, a), en tenant compte des vecteurs estimations de mouvement et des coefficients transformés obtenus dans le domaine compressé, c) transmettre l'ensemble des zones formant l'image.
