Adaptive Media Playout Algorithm Based on Delay Prediction
Liangbao Jiao · Jisuanji gongcheng · 2009
Aiming at the drawbacks in AMP-Live model,a NEW Adaptive Media Playout(NEWAMP) algorithm based on packet-delay prediction is proposed.The main modification is that,the predicted value of the future channel and the buffer state may be used as the basis of playout policies.Moreover,after thining the playout speed and considering the maximum end-to-end delay,the algorithm performance may be improved further.In contrast to the classical media playout,NEWAMP algorithm decreases the average buffer delay more than 50 percent with low enough packet loss ratio of overflow and downflow.To the traditional AMP-Live algorithm,not only the packet loss ratio of overflow and downflow is decreased,but also the average buffer delay is deceased almost 40 percent.Experimental results show this algorithm is effective.
