Abstract

Procédé pour la distribution de séquences vidéos selon un format de flux nominal (101) constitués par une succession d'images, chaque image étant constituée d'une succession de blocs, et dans lequel au moins un desdits blocs d'une desdites images est calculé par prédiction de mouvement par rapport à au moins une image dite de référence, ladite prédiction de mouvement étant codée dans le flux (101) avec au moins un vecteur de mouvement, ledit flux (101) sur lequel on procède, avant la transmission à l'équipement client (8), à une analyse pour générer un premier flux modifié, présentant le format d'un flux nominal, et présentant des images modifiées par la substitution de certaines données par des données de même nature, et un deuxième flux d'un format quelconque, comportant les données substituées et les informations numériques aptes à permettre la reconstruction dudit flux modifié, puis à transmettre séparément les deux flux ainsi générés depuis le serveur (12) vers l'équipement destinataire (8), et pour lequel on calcule sur l'équipement destinataire (8) une synthèse d'un flux au format nominal en fonction dudit premier flux et dudit deuxième flux caractérisé en ce que ladite modification consiste à modifier au moins un desdits vecteurs de mouvement.
