Design And Implement Of Client In Video Playing System On Wireless Mobile Terminal

With the development of the 3G network technology and the high efficiency of video compression technology, as well as the the well performance of mobile terminals, it becames possible that the wireless streaming media applications is widely used in mobile terminals.Video playing system on wireless mobile terminal is an interactive streaming media playing system in the wireless environment. With combining video abstract technology, video compression technology and streaming media technology, the system extracts the abstraction of the video, and then provides the video channel and video information as the preview for the users to select, which allows users to select and play the video clips according to their interest. And it greatly improves the user experience.In this thesis, the client subsystem in wireless interactive streaming media system is presented, it implements the gain of the media list information, the browsing of video abstract information, the real-time playing of the video clips and many other functions, and it provides users with new experience of touch screen. The paper introduces the related technologies which used in the wireless interactive streaming media system, including streaming media technology, video abstraction, HTTP, RTSP, etc. On the basis of existing technology, symbian mobile streaming media system solution is proposed. And it gives the customer terminal equipment requirements and functional description, and a detailed analysis of the client process.The focus of this thesis is to discuss the design and implementation of the interactive streaming media download terminal on the symbian platform. In the thesis, it introduces the building of symbian platform environment, program development and packaging. It divides the client subsystem into GUI module, player module and network communication module. And the interfaces and implementation methods of the modules is described detailly, the interaction is illustrated. Through analyzing the result of the system test, the functions of the system is validated, and it is proven that the system's function and performance meet the design requirements.In the end, we give the summary of the whole thesis, describe the current shortcomings of the client subsystem, future work and summary the work and research progress during master-degree study.
