Scheduling Algorithm Based on VBR Video Traffic Prediction for TS Multiplexers in DVB-H Networks
Bin Wang, Rong Ding · Dianzi xuebao · 2006
A challenge was brought to the scheduling algorithm of TS multiplexers by timeslicing technology adopted in DVB-H.We proposes a scheduling algorithm based on variable bit rate(VBR) video traffic prediction for TS multiplexers in DVB-H networks.This algorithm allocates the bandwidth of next scheduling cycle in advance by the prediction of VBR video traffic,and meets the requirement about scheduling algorithm needed by the technology of time-slicing.Our scheduling algorithm can achieve significantly lower delay and higher utilization of bandwidth,in comparison with CBR scheduling algorithm.
