Abstract
L'invention concerne un procédé de transmission d'une vidéo immersive entre une unité réseau et au moins un équipement de visualisation permettant à une pluralité d'utilisateurs de visualiser simultanément ladite vidéo immersive, la vidéo immersive comprenant une suite d'ensembles d'images chacune composée de blocs de pixels, la vidéo immersive étant transmise sous une forme compressée à chaque équipement de visualisation. Le procédé est mis en œuvre par l'unité réseau et comprend pour chaque ensemble d'images : obtenir (501) une information représentative d'un point de vue sur la vidéo immersive de chaque utilisateur ; déterminer (502) au moins une zone d'image, dite zone privilégiée, correspondant à au moins une partie des points de vue ; pour chaque image comprise dans l'ensemble d'images, appliquer (503) aux blocs de pixels n'appartenant pas à une zone privilégiée, un taux de compression en moyenne plus élevé qu'une moyenne des taux de compression appliqués aux blocs de pixels appartenant à une zone privilégiée ; et, transmettre (504) l'ensemble d'images à chaque équipement de visualisation.
