Video QoS Monitoring and Control Framework over Mobile and IP Networks

With the development of network technology, multimedia applications in various video forms are widely used in network services. In order to leverage video QoS, it becomes a pressing problem to monitor and control video QoS during network transmission of video. In this paper, we propose a monitoring and control framework for video QoS over IP and mobile network. Also, we develop a low computational complexity and more effective video quality assessment (VQA) method based on human visual system (HVS), Improved Human Visual Model (I-HVM), and propose Adaptive and Dynamic Sampling Strategy (ADSS) of video feature, to monitor video quality at both ends of our framework. The experimental results show that our framework can monitor well video QoS over IP and mobile network. Consequence, to leverage video QoS, dynamic control can be applied to transmission decision of video service according to the monitoring results of video QoS by our framework.
