Title
(EN) VIRTUAL REALITY VIEWPOINT VIEWPORT CENTER POINT CORRESPONDENCE SIGNALING
(FR) SIGNALISATION DE CORRESPONDANCE DE POINT CENTRAL DE FENÊTRE D'AFFICHAGE D'UN POINT DE VUE DE RÉALITÉ VIRTUELLE
Abstract
(EN)
A mechanism for virtual reality (VR) video coding is disclosed. The mechanism includes receiving a bitstream including at least a portion of a coded virtual reality (VR) video filmed from a plurality of viewpoints and including a correspondence between viewport centers for the viewpoints. The portion of the VR video at a center point of a source viewport at a source viewpoint is decoded and forwarded toward a display. The source viewpoint is switched to a destination viewpoint. A destination viewport is determined at the destination viewpoint based on the source viewport and the correspondence between viewport centers for the viewpoints. The portion of the VR video at a center point of the destination viewport at the destination viewpoint is decoded and forwarded to the display.

L'invention concerne un mécanisme de codage vidéo de réalité virtuelle (RV). Le mécanisme consiste à recevoir un flux binaire comprenant au moins une partie d'une vidéo de réalité virtuelle codée (VR) filmée à partir d'une pluralité de points de vue et comprenant une correspondance entre des centres de fenêtres d'affichage pour les points de vue. La partie de la vidéo VR à un point central d'une fenêtre d'affichage source au niveua d'un point de vue source est décodée puis transmise à un dispositif d'affichage. Le point de vue source est commuté vers un point de vue de destination. Une fenêtre d'affichage de destination est déterminée au niveau du point de vue de destination d’après la fenêtre d'affichage source et la correspondance entre les centres des fenêtres d’affichage pour les points de vue. La partie de la vidéo VR à un point central de la fenêtre d'affichage de destination au niveau du point de vue de destination est décodée puis transmise au dispositif d’affichage.
