Designing And Implication Of Streaming Media Client Based On Windows Mobile

Mobile streaming media technology is a hot topic in research these yeas. But, at the present time, most streaming media systems mainly focus on desktop computer or base on Web. Along with 3G business has officially entered the commercial phase and intelligent terminal mobile develops rapidly, mobile streaming media technology has broad market demand on mobile phone, remote education, mobile TV and video conference have been universal step by step. Based on the background, this paper combines actual demand, designs and implements streaming client based on Windows Mobile phone, especially processes the the algorithm optimization for H.264 JM decoder .The main work of this paper:1) Introduce the background and application of the project, by analytic comparison of the current and trend situation of smart phone and determine to use Windows Mobile operating system as the project platform. Describe the overview of Windows Mobile operating system, and discuss the the key technology of streaming media.2) Analyse the user demand of the client, the main framework of the system, and disucuss the design plan of streaming client based on Windows Mobile phone in detail. Divede the client into user interface, media engine and the control of network data transmission.3) Research the algorithm of Audio/Video synchronization, due to the phenomenon of not perfect Audio/Video synchronization during playing, access some advantage and disadvantage of algorithm of Audio/Video synchronization, design and implement the plan of video synchronization to audio.4) Due to the unefficent of parsing ini text on terminal mobile, put forward an design plan based on limited state machine, and achieve some effect.Based on the above work, in the China Mobile TD-SCDMA network environment, we test the client's functionality and performance. It successfully implements the basic functions of streaming media playing, with good fluency and user experience.
