摘　　要：介绍了一种基于Symbian智能手机的视频共享系统。智能手机将拍摄的视频内容压缩后通过无线信道上传到服务器,其它智能手机可以从该服务器上下载上传的视频内容,或者以流的方式进行实时解码播放。本文阐述了该系统的整体结构,重点介绍了客户端软件的设计与实现,包括Symbian平台上H.264视频编解码器以及视频传输模块的实现;实现了一个原型系统,并给出系统性能的测试结果。该系统的现实意义在于充分利用移动通信优势来满足人们视频应用的需求,使得人们相互间可以方便地共享身边的场景。A Symbian-based smartphone video sharing system is introduced,in which the videos captured by the smart phone onboard camera are uploaded to server after being compressed, then those videos can be downloaded from server to other smart phones,or be downloaded with video streaming and then be decompressed g〉 played. In this paper, the architecture of the system is described. The design and implementation of client applications is the most important part, including the implementation of H. 264 video codec on the Symbian platform and video transmission module. Finally a prototype system is implemented and the performance testing results are given. The practical significance of this system lies in its ability to satisfy the people＇s demand for that it is very convenient to share scene around each other,with the advantages of mobile communications.
