Methods, devices and stream are disclosed to encode and decode a volumetric content. At the encoding, the space of the volumetric content is divided in distinct sectors according to at least two different sectorizations. One atlas is generated for each sectorization or a single atlas is generated encoding all the sectorizations. At the decoding, a sectorization is selected according to the current direction and field of view, according to user's gaze navigation and according to prediction of the upcoming pose of the virtual camera controlled by the user. Sectors are selected according the selected sectorization and the current direction and field of view and only patches encoded in regions of the atlas associated with these sectors are accessed to generate the viewport image representative of the content seen from the current point of view.

Method and apparatus for encoding and decoding volumetric video

Methods, devices and stream are disclosed to encode and decode a scene (such as a point cloud) in the context of a patch-based transmission of a volumetric video content. The present principles relate a method of dividing an atlas image in regions, a region being associated with a sector of the space of the scene and packing patches obtained by projecting points comprised in the associated sector only. The atlas and related metadata are encoded in a data stream; At the rendering, a set of sectors is selected based on the current field of the user. Only pixels of regions associated with the selected sectors are accessed to generate the viewport image representative of the scene viewed from the current point of view.

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.

Devices and methods for generating and rendering immersive video

A method and an apparatus for decoding a volumetric video are disclosed. Such a method comprises receiving a data stream representative of a file comprising information for selecting, according to a rendering viewpoint, at least one atlas comprising color and depth data patches associated with a viewpoint in said volumetric video, said color and depth data patches being generated with respect to depth and color reference data acquired from a reference viewpoint in said volumetric video.

Method and apparatus for decoding a 3D video

A method and device for packet processing implemented by a packet processing device is described. The packet processing device is connected to a communication network from which the packet processing device receives and/or transmits packets in a context of network service chaining. The method includes obtaining a set of packets, each packet of the set of packets comprising at least one specific characteristic; grouping the packets of the set of packets according to the at least one specific characteristic, and delivering at least two subsets of packets; and adding, to at least one of the subsets of packets, metadata common to the packets of the at least one subset of packets.
