| In recent years, with the continuous development of mobile internet, there are more and more mobile streaming media systems that can be downloaded from internet. As the 3G network has higher data transmission rate and data service capability, 3G network operators can not only provide users with high quality voice service, but also to provide high-speed streaming media business.Firstly, this paper discusses the development of streaming media systems based on mobile internet, analyzes the characteristics of several popular mobile streaming media system at home and abroad and summarizes several problems of the mobile streaming media service. To solve these problems, this paper presents a mobile streaming media system. This system is based on 3G network and WiFi. In addition to providing live video and on-demand video, this system has also achieved some distinctive features like time-shifted TV and ordered recording.Next, this paper discusses the key technologies of the mobile streaming media system. The paper starts with a general analysis of the system's business logic framework, overall technical architecture and function modules. Then this paper analyzes the design of some important modules of the system like live video module, on-demand video module, time-shifted TV module, ordered recording module, advertising module and load balance module.Finally, this paper describes some tests of streaming media server and load balance module. The end of the paper summarizes the practical significance and innovation of this research and proposes further research. |
