Abstract—Along with the rapid development of 3G and 4G technologies, mobile video services have gained its popularity among users around the world. Consequently, Content Providers (CPs), Service Providers (SPs), and especially, the operators are paying increasing attentions to the quality of experience (QoE) of the video services which could be easily affected by the quality of network. In this paper, a novel real-time objective video QoE assessment method is proposed and a software assessment system is built to test the video service quality in the real network. Firstly, in the test terminals, the QoE measurement of the entire video services is conducted by collecting all of the customers’ experience in full-reference method, and then the QoE scores are evaluated through an accurate mathematic model. Secondly, the artifact of compression caused by video encoding should also be taken into account. Model in this part adopts no-reference method in consideration of the varied screen sizes in different terminals. What’s more, the platform also evaluates the error of network in the part of video transmission by associating no-reference PSNR with network delay, jitter, and packet loss ratio. The results of Mean Opinion Score (MOS) tests show that the proposed models estimate QoE with high quality estimation accuracy respectively. We develop a software toolkit using the test methodologies above, which can help the operators to make measurements for its network. This software toolkit is useful as a QoE monitoring tool on video streaming services and can be deployed on real network conveniently.
