Abstract
Examples of the present invention provide a method of delivering media, such as a video sequence, to a client device from a server, taking into account the relative importance of different portions of the video sequence. The sequence is divided into temporal segments, with each segment encoded at a plurality of bitrates (and hence qualities). A viewer importance parameter is assigned to each segment, indicating the relative importance of that segment, with the information stored in a manifest file or similar. The client receives this segment and viewer importance data in a manifest file. As soon as the client is aware of a future segment marked as having higher viewer importance than the next segment for download, the client initiates the download of this further segment by making a request (e.g. HTTP request), while making a concurrent request for the delivery of the next segment.
