With the mobile communication technology developing rapidly, wireless bandwidth can be used more and more, which will make high-speed video services occupy most of the wireless communication traffic. This paper presents a QoE evaluation model based on video content, combined with video jitters and packet loss rate. The experimental results show that the evaluation results of the model can reflect the video QoE better and have good performance. INTRODUCTION In the process of network technology developing rapidly, real-time data such as voice and video in the network are in large scale[1]. However, due to the limited bandwidth of the network, the video needs to be compressed before transmission. In the process of transmission and other issues, which led to the user finally received the video data, and the original video data there are some differences. The degree of this video distortion will have a significant impact on the Quality of Experience (QoE)[2]. At present, the existing video evaluation standard is mainly through the difference between the source video and received video’s parameters to get the video distortion, or combined with the transmission process of network services parameters to establish the QoE evaluation model[3]. However, this evaluation standard ignores the influence of video content on the subjective feelings of users. This paper consider the characteristics of video content and the quality of service parameters of transmission network, and establishes a QoE evaluation standard based on video content . In the test of mathematical models it also considers the user's subjective feelings. ORGANIZATION OF THE TEXT The effect of video jitters and packet loss on QoE The jitters in the network makes the video stream receiving time not constant, usually if the video stream packet jitters time exceeds a certain threshold range decoder, it will discard this packet, which directly affect the video stream in the terminal display[4]. In this section, the QoE values of video transmission under different jitters conditions are obtained experimentally. The delay is set to 120 ms during the experiment. The experimental results are shown in Figure 1. At the same time, the experimental results shows when video objects and background changes violently, the user experience value will be more sensitive to jitters. 584 5th International Conference on Frontiers of Manufacturing Science and Measuring Technology (FMSMT 2017) Advances in Engineering Research (AER), volume 130
