摘　　要：3G移动网络的高速数据传输能力使得移动流媒体的实现成为可能。本文从移动网络和移动流媒体传输协议的特点入手,结合DirectShow开发多媒体的优势,探讨了移动流媒体播放器设计中的流媒体服务器的交互、缓冲区的设置、视音频同步以及RTSP源过滤器等关键技术,研制出一个适用于移动网络环境的流媒体播放器,并进行了实际验证和测试。With the bandwidth increasing of mobile network from GPRS,CDMA to 3G,which makes it possible to play streaming media on mobile device. A new type of mobile streaming media player based on DirectShow platform is proposed due to its good performance for multimedia functionalities. The paper gives the solution to the main techniques related to mobile media player, such as streaming media server interaction, buffer setting, video and audio synchronization and RTSP Source Filter, and so on. Based on these key techniques, a mobile streaming media player has been implemented and verified on the mobile network environment.
