Bandwidth adaptive smoothing for multimedia delivery
Jae‐Wook Kim, Rhan Ha, Hojung Cha · 2002
Providing a satisfactory multimedia application service in networking environments requires an effective media delivery mechanism. However, a common network such as the Internet does not provide a guaranteed network bandwidth to accommodate multimedia service in a reliable fashion. A typical approach to assist multimedia delivery is via buffer management in the end system. Buffer management techniques are classified into two categories: one is adapting the changes in network load and the other is smoothing the bandwidth requirement. The former may cause a serious loss of service quality and the latter is not able to adapt to the dynamic network condition. The authors propose bandwidth adaptive smoothing which is adaptive to the dynamic networks and also supports better quality of service by smoothing the bandwidth requirement. Simulation results with a prerecorded MPEG video, show that the quality of video delivered is improved with the proposed technique.
