QoS Assured Multi-rate H.264 Scalable Video Multi-cast with Network Coding in Lossy Networks
In this paper, the authors propose a new multi-rate H.264 scalable video multicast in lossy network using network coding. They first prioritize video layer based on its effect to the end-to-end video quality. Each video layer is routed via the path obtained from the optimization framework under the constraints on Quality of Service (QoS) guarantees. The data transmissions of lower layers, which are more important for decoding process in video reproduction, are assigned to more reliable paths with QoS guarantee to further improve user's experience.
