Abstract
Immersive 3D video content includes a plurality of preferably overlapping cells, each cell representative of a volume in the content, wherein a cell providing both content corresponding to a virtual central camera in the cell and parallax information from virtual peripheral cameras around the centre position can be next to a cell providing only parallax information to be used with the content corresponding to the virtual central camera. A device for rendering immersive video, renders a viewpoint corresponding to a user's current position, tracks and predicts the user position, and if the user position moves to a cell with central camera content, retrieves the content and parallax information, and if the user position moves to a cell with only parallax information, retrieves the parallax information and, if necessary, also the cell with the content. This arrangement can reduce bandwidth and storage for the immersive 3D video content.
