Xiaomei Zhang · Railway Computer Application · 2005
A new QoS mapping for streamed MPEG-4 video based on differientiated service was presented.In this mechanism,QoS indexes were defined based on available network bandwidth and the frame type of MPEG-4 to set the type of service.Inorder to differientiate service,different management and different attemper of queue were taken.The simulation resultsshowed that the proposed QoS mapping could take advantages of the DiffServ architecture,make an improvement in thevideo quality.
