METHOD AND NETWORK EQUIPMENT FOR ENCODING AN IMMERSIVE VIDEO SPATIALLY TILED WITH A SET OF TILES

An encoder (310) configured for encoding an immersive video spatially tiled with a set of tiles in one or more representations, a tile covering a portion of a scene of the immersive video, said immersive video being temporally divided into a plurality of video segments, a video segment being further defined by a plurality of tile segments, a tile segment being associated with a tile of the set of tiles,wherein the encoder (310) comprises one or more memories (314) and one or more processors (313, 315), configured for:- obtaining, for each time section among a set of time sections temporally dividing the immersive video, proximity values associated with the tiles representing a proximity of the tiles with respect to a region of interest of the scene,- assigning, for each time section, bit-rate upper limits to the tiles depending on the obtained proximity values of the corresponding tiles,- encoding, for each time section, the tiles of the set of tiles according to one or more representations in accordance with their corresponding assigned bit-rate upper limits.
