Abstract
A method for adaptive streaming of video is described, wherein the method comprises: transmitting first metadata to a client apparatus, the first metadata defining a first adaptation set, an adaptation set defining one or more sets of segment identifiers, each set of segment identifiers defining a plurality of linearly playable media segments of a predetermined resolution, each media segment in a set of media segments having an identical playback duration, the first metadata enabling a client apparatus to request media segments and sequentially playout the media segments; receiving navigation information from the client apparatus, the navigation information defining at least a first region, in the video frames of the first adaptation set; selecting second metadata defining a second adaptation set on the basis of spatial playback information and a spatial distance or a spatial overlap between the first region and a second region in video frames of the first adaptation set, wherein the spatial playback information signals the server apparatus that the second region is linked to media segments of the second adaptation set; and, transmitting the second metadata or information for retrieving the second metadata to the client apparatus, the second metadata enabling the client apparatus to playback media segments of the second adaptation set after the playback of media segments of the first adaptation set.
