摘　　要：移动媒体业务发展势头强劲,目前存在于GPRS网络上的移动视频点播系统还存在着一些问题,点播效果不太理想.文章对此问题进行了深入的分析,提出一种依托于JXTA和JXME为底层P2P通信体系的移动视频点播系统,对整个点播系统的体系架构进行了一定的分析和设计,并对其中的无线通讯、移动流媒体传输与播放、数据冗余策略等关键技术进行了分析和论证,最后通过一个仿真实验,在一定程度上,验证了该系统的优势和可行性。The development of mobile media business is very strong currently, there are some actual problems in the mobile VOD system of GPRS network and the VOD result is paper, the main problems are analyzed, and a new mobile VOD system of P2P structure of JXTA/JXME is presented, the whole architecture of the system is the key techniques such as wireless communication, the transfers and playing data redundancy strategies, and data transmission scheduling mechanism are Finally, to a certain extent, not very satisfying. In this based on the communication analyzed and designed, and of mobile streaming media, analyzed and demonstrated. the feasibility and advantages of the system are verified by a simulation experiment.
