Title
(EN) AUGMENTED REALITY SUPPORT IN OMNIDIRECTIONAL MEDIA FORMAT
(FR) PRISE EN CHARGE DE RÉALITÉ AUGMENTÉE DANS UN FORMAT DE MÉDIA OMNIDIRECTIONNEL
Abstract
(EN)
A method, apparatus, and computer program are provided for decoding and rendering an omnidirectional media bitstream, wherein the media derived from the omnidirectional media bitstream comprises a background layer. The method includes acquiring an omnidirectional media bitstream. The method further includes determining, from the omnidirectional media bitstream, whether there is transparency in the background layer. The method further includes responsive to determining that there is transparency in the background layer, decoding and rendering the omnidirectional media bitstream with transparency in the background layer. The method further includes responsive to determining that there is no transparency in the background layer, decoding and rendering the omnidirectional media bitstream without transparency in the background layer.

La présente invention concerne un procédé, un appareil et un programme d’ordinateur permettant de décoder et de rendre un flux de bits de média omnidirectionnel, le média déduit du flux de bits de média omnidirectionnel comprenant une couche d’arrière-plan. Le procédé comprend l’acquisition d’un flux de bits de média omnidirectionnel. Le procédé comprend en outre le fait de déterminer, à partir du flux de bits de média omnidirectionnel, s’il y a une transparence dans la couche d’arrière-plan. Le procédé comprend en outre, en réponse au fait de déterminer qu’il y a une transparence dans la couche d’arrière-plan, le décodage et le rendu du flux de bits de média omnidirectionnel avec la transparence dans la couche d’arrière-plan. Le procédé comprend en outre, en réponse au fait de déterminer qu’il n’y a pas de transparence dans la couche d’arrière-plan, le décodage et le rendu du flux de bits de média omnidirectionnel sans la transparence dans la couche d’arrière-plan.
