Adaptive Quality Of Service For Streamed Mpeg-4

In streaming technologies, multimedia data is continuously fed to the user while they are processing (viewing, listening to, reading) the data. However, streaming with a specified Quality of Service (QoS) is not yet a solved problem. We are building a prototype system to adapt multimedia streaming to a fluctuating network load and/or client requests, thereby providing adaptive QoS. We have shown the feasibility of adjusting QoS levels during transmission by dynamically modifying which transmission layers are actually sent, as well as the transmission profiles and packet priority ratios
