Abstract: A method is described for rendering a spatial part of an immersive video on a display of a client device comprising a tile frame retrieval device, a decoder device and a renderer device, wherein the immersive video comprises video frames, each video frame being spatially divided in tile frames, and the immersive video comprises tile streams, each tile stream representing a spatial part of the immersive video and each tile stream comprising a plurality of said tile frames, and wherein the client has stored tile stream mapping information, that indicates for each tile stream a respective position on a surface of a two-dimensional or three-dimensional model, such as a sphere or cube, the method comprising based on said tile stream mapping information and a viewport, the tile frame retrieval device determining a plurality of tile streams, and requesting encoded video data from a server, the encoded video data comprising, for each determined tile stream, an encoded tile frame that comprises encoded data representa

Abstract: A method of transmitting a request for video data comprises a client device transmitting a request for high-resolution spatial-element frames of a spatial element of a video to a distribution node for each spatial element of the video in a user's field of view for which a client device does not possess a current high-resolution spatial-element frame. The video comprises a plurality of spatial elements and the plurality of spatial-element frames comprises both non-inter-coded spatial-element frames (152) and inter-coded spatial-element frames (151). The request identifies the spatial element and specifies a starting point (179) corresponding substantially to a current time. The request is for data comprising a temporal segment of high-resolution spatial-element frames starting substantially at the starting point (179) and of which the first high-resolution spatial-element frame (173) is not inter coded. The method further comprises the client device receiving the requested data.
