Abstract: A method is described for processing an omnidirectional video by a client device, said omnidirectional video being associated with a 3D coordinate system for determining a spatial position of video data of said omnidirectional video on a curved surface, preferably a sphere, said method comprising: receiving a manifest file, the manifest file comprising a plurality of tile stream identifiers for identifying a plurality of tile streams, the tile streams comprising video frames having image views, whereby the image views of video frames of different tile streams cover different regions of a 2D projection of the omnidirectional video, a region defining a tile; selecting on the basis of spatial relation information in the manifest file and on the basis of a viewpoint of a user of the client device a first tile streams associated with a first resolution and a first tile position and a second tile stream associated with a second resolution and a second tile position, the second resolution being lower than the first

Abstract: Encoded video data representing partial video images is decoded from a first video stream such as a HEVC bitstream. The first video stream comprises video images divided into a spatial array of independently decodable slices. The first video stream comprises network abstraction layer units that each contain video content data for a respective one of the slices preceded by a header that comprises parameters relating to the respective one of the slices in relation to the first video stream. Previously prepared information such as meta data about positions of parameters in the network abstraction layer units or a plurality of different versions of the network abstraction layer units for different partial image sizes (different picture sizes) is used.
