Title (EN) THREE-DIMENSIONAL VIDEO PROCESSING
(FR) TRAITEMENT DE VIDÉO EN TROIS DIMENSIONS
Abstract:
(EN) A method and system for three-dimensional video content processing is disclosed comprising an operation of receiving first video data representing three-dimensional video content arranged as a plurality of first tiles associated with respective sub-areas of an image. Another operation comprises providing data indicating for each first tile a depth range of video content within said tile. Another operation comprises determining for each first tile a respective volume based on the depth range. Another operation comprises determining a field of view of a user in relation to the first tile volumes. Another operation comprises rendering of the first video data for one or more first tiles only if their determined volume is at least partially within the field of view.
(FR) L'invention concerne un procédé et un système de traitement de contenu vidéo en trois dimensions, consistant : à recevoir des premières données vidéo représentant un contenu vidéo en trois dimensions agencé sous la forme d'une pluralité de premiers pavés associés à des sous-régions respectives d'une image ; à fournir des données indiquant pour chaque premier pavé une plage de profondeur de contenu vidéo dans ledit pavé ; à déterminer pour chaque premier pavé un volume respectif sur la base de la plage de profondeur ; à déterminer un champ de vision d'un utilisateur par rapport aux premiers volumes de pavé ; à rendre des premières données vidéo pour un ou plusieurs premiers pavés uniquement si leur volume déterminé s'inscrit au moins partiellement dans le champ de vision.
