分组网络中的视频质量评估

Quality evaluation of video over packet networks

分组网络中的视频质量评估虽然从理论上可以采用一般的视频质量评估方法,但是由于视频在网络上传输的特殊情况以及宽带业务运营的要求,需要满足实时性高、资源开销小等要求。首先描述了分组网络中的视频质量评估方法及其模型分类,介绍了目前在分组网络中的视频质量评估方面的研究成果,并分析和总结了它们的优缺点及性能;最后展望了评估方法及模型的发展。

Quality evaluation of video over paeket networks can use the general methods of video quality evaluation,but it has to meet the special requirements of quality evaluation in packet networks, such as real-Lime,low cost of resource ete. This paper firstly deseribed the classification of the methods and models in the quality evaluation of video over packet networks, then in- trodueed the present methods and models in the topic, and analyzed their merit and demerit, and performanee,finally gave the perspective of quality evaluation of video over packet networks.
