Abstract
In adaptive streaming, video segments are available in one or more quality levels, and each video segment is delivered to the client (103) in a quality level specified in a request received from that client (103). In order to reduce the risk for buffer underrun, an adaptive streaming aware network node (101) comprises: —session monitoring means (111) for collecting buffer fill information indicative for a buffer volume at the client (101) occupied by a video session; —priority calculation means (112) for determining a priority level for video segments of the session in function of the buffer fill information; and —video segment marking means (113) for marking video segments of the session with the priority level.
