Synthesis of an image of a view from data of a multi-view video. The synthesis includes an image processing phase as follows: generating image synthesis data from texture data of at least one image of a view of the multi-view video; calculating an image of a synthesised view from the generated synthesis data and at least one image of a view of the multi-view video; analysing the image of the synthesised view relative to a synthesis performance criterion; if the criterion is met, delivering the image of the synthesised view; and if not, iterating the processing phase. The calculation of an image of a synthesised view at a current iteration includes modifying, based on synthesis data generated in the current iteration, an image of the synthesised view calculated during a processing phase preceding the current iteration.

A method performed by an electronic device for requesting tiles relating to a viewport of an ongoing omnidirectional video stream is provided. The ongoing omnidirectional video stream is provided by a server to be displayed to a user of the electronic device. The electronic device predicts for an impending time period, a future head gaze of the user in relation to a current head gaze of the user, based on: A current head gaze relative to a position of shoulders of the user, a limitation of the head gaze of the user bounded by the shoulders position of the user, and a current eye gaze and eye movements of the user. The electronic device then sends a request to the server. The request requests tiles relating to the viewport for the impending time period, selected based on the predicted future head gaze of the user.
