经过多年的发展，内容网络（CN）已经变得越来越复杂，技术上也越来越多样化。现代CN被设计为更适应通信环境、设备和用户需求。然而，一个悬而未决的问题是提供服务的质量仍在波动。因此，用户体验可能会受到负面影响。为了保持令人满意的用户体验水平，开发一种可行的解决方案来衡量视频服务满足用户期望的程度是至关重要的。根据用户的主观意见评估视频质量是一项复杂的任务。在本文中，我们解决了这一任务的挑战，并设计了一个综合框架，使用一些全面的功能模块。我们的框架集成了客观的质量评估模型的文物测量（AM）和交付质量（QoD）的方法。只有最合适的模型被激活的框架考虑到个人的评估任务的要求。我们还介绍了我们最近的工作，实现框架的关键功能模块。两个研究所之间的联合主观实验也进行了模型的实施和评估的目的。实验结果验证了综合框架的概念，并显示其关键模块的有效性，估计视频服务的质量水平。
Through years of development Content Networks (CN) have become more sophisticated and more technically diverse. Modern CN are designed to be more adaptive to communication environment, devices and user requirements. However, one open issue is the still fluctuating quality of service provision. As a result user experience can be negatively affected. In order to maintain a satisfactory level of user experience it is crucial to develop a feasible solution to measure the extent to which video services meet users' expectation. Assessing video quality with respect to users' subjective opinions is a complex task. In this paper we address challenges of this task and design an integrated framework using a number of comprehensive functional modules. Our framework integrates objective quality assessment models of Artifacts Measurement (AM) and Quality of Delivery (QoD) approaches. Only the fittest models are activated by the framework considering requirements of individual evaluation tasks. We also introduce our recent work of realising key functional modules of the framework. Joint subjective experiments between two institutes have also been carried out for the purpose of model implementation and evaluation. Results from experiments verify the concept of an integrated framework and show the effectiveness of its key modules in estimating the quality level of video services.
