ADAPTIVE STREAMING AWARE NETWORK NODE, CLIENT AND METHOD WITH PRIORITY MARKING

摘要

In adaptive streaming, video segments are available in one or more quality levels, and each video segment is de livered 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.

1. An adaptive streaming aware network node able to stream video segments of a video session to a client, said video segments being available in one or more quality levels, and each video segment being delivered to said client in a quality level specified in a request received from said client,
wherein said adaptive streaming aware network node comprises: session monitoring means for collecting buffer fill information indicative for a buffer volume at said client occupied by said video session; priority calculation means for determining a priority level for video segments of said session in function of said buffer fill information; and video segment marking means for marking video segments of said session with said priority level.
