Abstract

A method performed by a server of a communication network for making an HTTP media stream accessible to a client is provided. A Media Presentation Description (MPD) is generalized, such that the MPD is provided with at least one period element sequentially arranged according to a media play timeline. Each period element is provided with at least one representation such that at least one of the period elements is provided with at least two alternative representations. Each representation is provided with an ordered sequence of at least one media segment URI. Each media segment URI references at least one media segment of the HTTP media stream. The generated MPD enables a client to select representations and to acquire referenced media segments based on the selected representations.
