| Abstract: | IPTV is interactive internet protoeol TV.The enhancement of QoS is of great significance for the promotion and development of IPTV.Considering the Quality of Service in IPTV system and the scheduling algorithm of WiMAX,this paper proposes an improved scheduling algorithm,which aims at meeting requirements of IPTV＇s QoS.To decrease the delay of real-time traffic,the weight of different business is calculated,which ensures the priority of real-time business.Simulation result shows that the policy has good performance in delay and throughput.It can promote the QoS performance of IPTV system. |
