摘要
目前的网络视频传输质量监控模型大多是针对UDP的,而TCP视频传输质量监控模型的建立仍是一个待解决的问题。在基于MDI算法的UDP视频传输质量监控模型基础上,提出了能有效实时反应TCP视频传输质量的八个评估指标,并创建对应的监控模型进行实时指标计算。实验结果证明了该模型的可靠性和实用性。
The present network streaming media quality monitoring models are mostly only applicable to UDP streaming media, while TCP streaming media quality Monitoring Model building is still an unsolved problem. Through the study of the present UDP streaming media quality Monitoring Model based on MDI algorithm, This paper introduces eight indexes which can rcflect the present TCP streaming media quality effectively, and the model is built to calculate the indexes. Experiment shows that the model is reliable and can be used widely.
