Abstract
Methods and devices for encoding and decoding 3D scenes of an immersive video are disclosed with the related data stream. Taking advantage of the fact that parts of the 3D scene does not change from one frame of the video to another, even when the cameras move and/or the lighting condition change, dynamic and static parts of the 3D scene are encoded in different atlases. In an embodiment, static patch atlases are repeated between two updates. In another embodiment, only updates are encoded and transmitted. The decoder maintains a memory associating entity of the 3D scene with a set of static patches that is updated with instructions linked to update static patch atlases. At each presentation time the static part of the 3D scene to decode is obtained from the memory.
