Abstract

L'invention concerne un procédé de codage et un dispositif de codage d'un flux de données représentatif d'une vidéo omnidirectionnelle, et corrélativement un procédé de décodage et un dispositif de décodage d'un flux de données représentatif d'une vidéo omnidirectionnelle. Selon l'invention, le flux de données représentatif d'une vidéo omnidirectionnelle comprend des données codées d'au moins une couche de base représentative d'une vidéo 2D ou 3D représentative d'une vue d'une scène capturée par la vidéo omnidirectionnelle, et des données codées d'au moins une couche de rehaussement représentative de la vidéo omnidirectionnelle, la au moins une couche de rehaussement étant codée par prédiction par rapport à la au moins une couche de base.
