Abstract: Methods, apparatus and streams are disclosed for encoding, transmitting and decoding volumetric video. Volumetric video is encoding in the form of a patch atlas sequence. The patch atlas is generated, and a sub-set of patches is selected to be partitioned, for instance on a size criterion. Metadata are associated with the atlas in a data stream to indicate which and according to which partitioning mode patches are encoded. At the rendering side, a level of sampling level is selected according to memory and processing resources of the end-device. Only parts of partitioned patches are decoded as a function of the selected sampling level.

Abstract: The invention is related to a 3D (three-dimensional) scene presenting method and associated devices using a shared reference document and a corresponding set of 3D update document. When the presentation engine is triggered to access or present a target 3D scene among the set of target 3D scenes, it parses the shared reference document and the corresponding 3D scene update document among the set of 3D scene update documents to generate the target 3D scene description document describing the to-be accessed or presented 3D scene, renders the generated description document and updates the presenting 3D scene as the target scene.

Abstract: 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.

Abstract: Example apparatus disclosed herein to implement signature matching with meter data aggregation for use in media identification applications include a match job aggregator to aggregate batches of meter data from a meter to form aggregated meter data associated with the meter, and a hash matcher to identify a valid hash key match between meter hash keys generated from meter signatures in the aggregated meter data and reference hash keys corresponding to a collection of media assets. Disclosed example apparatus also include a signature matcher to align, based on the valid hash key match, a sequence of reference signatures corresponding to a first media asset associated with the valid hash key match and a corresponding sequence of the meter signatures, and compare the sequence of reference signatures and the corresponding sequence of meter signatures to identify media represented by at least a portion of the sequence of the meter signatures.
