Patent ID: 11893679

Abstract:
The disclosure discloses methods and devices for transmitting and rendering a 3D scene. The method for transmitting comprises: segmenting a space into m angular sectors, the m angular sectors each corresponding to an angular distance from a viewport, and the space into n depth ranges; obtaining (11) at least one first patch, generated from a first view of the 3D scene, said at least one first patch comprising a texture component and a depth component; obtaining (12) at least one atlas, generated from at least one second view of the 3D scene, said at least one atlas being built by packing together at least one second patch generated for at least one point of one of said second view that is not visible in another view of the 3D scene and that belongs to a same angular sector among the m angular sectors, and a same depth range among the n depth ranges, at least one of morn being greater than or equal to 2, said at least one second patch comprising a texture component and a depth component, wherein each of the at least one first patch and the at least one second patch is based on at least one of a sector and a depth; generating (13) a first subset of streams comprising m′ pairs of streams and a second subset of streams comprising m′×n′ pairs of streams; and transmitting (14) the first and second subsets of streams to the terminal.
