Nowadays, mobile WEB video application got rapid development, and the video service quality evaluation and the analysis of the network performance have become an urgent demand. In this paper, we propose a new framework and method to assess the subjective quality of mobile web video based on no-reference (NR) model. Through discuss the structure of TD mobile network and the application of web video, the paper built a set of testing process for mobile video on demand service and fault location method based on the result of network structure and the business of video quality evaluation. The actual test results from TD network shows the proposed way can measure the web video quality and find the bottleneck location of the transmitting network. The evaluation result of video on demand quality is in accordance with the subjective feeling of the user. The benchmark contrast testing method proved to be practical and feasible in the real test, thus providing readily available tools for video service quality assessment.

The advance of wireless and mobile technology introduces a new type of Video-on-Demand (VOD) systems, namely the mobile VOD systems, that provide VOD services to mobile clients. It is a challenge to design broadcasting protocols for such systems because of the following special requirements: (1) fixed maximum bandwidth requirement: the maximum bandwidth required for broadcasting a movie should be fixed and independent of the number of requests, (2) load adaptivity: the total bandwidth usage should be dependent on the number of requests; the fewer the requests the smaller the total bandwidth usage, and (3) clients sensitivity: the system should be able to support clients with a wide range of heterogeneous capabilities. In the literature, there are some partial solutions that give protocols meeting one or two of the above requirements. In this paper, we give the first protocol that meets all of the three requirements. The performance of our protocol is optimal up to a small constant factor.
