| 1 | A Survey of Multimedia Big Data显示文摘Multimedia big data brings tremendous challenges as well as opportunities for multimedia applications/services. In this paper, we present a survey and tutorial for multimedia big data. After discussing the characteristics of multimedia big data such as human-centricity, multimodality, heterogeneity, unprecedented volume, and so on, this paper provides an overview of the state-of-the-art of multimedia big data, reviews the latest related technologies, and discusses the technical challenges. We conclude this paper with a discussion of open problems and future directions. | Zaijian Wang Shiwen Mao Lingyun Yang Pingping Tang | 2018 | China Communications2018，15，1： | 1 |
| 2 | Quality of experience evaluation of HTTP video streaming based on user interactive behaviors显示文摘User interactive behaviors play a dual role during the hypertext transfer protocol(HTTP) video service: reflection and influence. However, they are seldom taken into account in practices. To this end, this paper puts forward the user interactive behaviors, as subjective factors of quality of experience(QoE) from viewer level, to structure a comprehensive multilayer evaluation model based on classic network quality of service(QoS) and application QoS. First, dual roles of user behaviors are studied and the characteristics are extracted where the user experience is correlated with user interactive behaviors. Furthermore, we categorize QoE factors into three dimensions and build the metric system. Then we perform the subjective tests and investigate the relationships among network path quality, user behaviors, and QoE. Ultimately, we employ the back propagation neural network(BPNN) to validate our analysis and model. Through the simulation experiment of mathematical and BPNN, the dual effects of user interaction behaviors on the reflection and influence of QoE in the video stream are analyzed, and the QoE metric system and evaluation model are established. | Li Wenjing Yu Peng Wang Ruiyi Feng Lei Dong Ouzhou Qiu Xuesong | 2017 | The Journal of China Universities of Posts and Telecommunications2017，24，3： | 0 |
