Designation And Implementation Of Mobile Streaming Media Based On BREW Platform

Compared with computer, the client of mobile streaming media has smaller size,limited process power and always was placed in the wireless environment. So the highquality of client’s processing power is quit important.A mobile streaming media system solution based on BREW platform waspresented in the thesis. We focus on the client’s designation, implementation andimprovement. We research a coding and transmission strategy used in the BREWplatform that is already optimized by us. The designation and implementation of theclient is studied profundity. The five modules of the client (including network, audioplaying, video decoding and displaying, audio and video synchronization, cachingmechanism) are analysis and improved. Data packets transmitted from the server arereceived and recombines by the client, audio and video are decoded and displayedrespectively. Though this the client implements a various operations of streaming mediaincluding play, pause, fast forward, rewind, stop, sound/brightness adjustment and so on.Concurrent events that may be appeared in the implementation of streaming media aredesigned and implemented. In order to improve the serve quality and the client’sprocessing speed, the MDP technologies are employed at the stream media client. Theresults shows that they can reduce the utilization of the mobile’s ARM.
