摘要
介绍了以IntelXScale处理器PXA270为核心的嵌入式系统平台,分析了IPv6组播与流媒体协议原理,移植了对IPv6有良好支持的Linux操作系统及Qtopia嵌入式图形系统。在此基础上,针对上述嵌入式系统移植和优化开放源代码的优秀媒体播放器MPlayer,实现了支持IPv6组播与流媒体传输的嵌入式IPv6网络视频终端。随后对该视频终端的媒体播放性能进行了测试与分析,并搭建了移动IPv6试验床,通过与IPv6网络流媒体服务器联机验证了视频终端功能。
An embedded platform based on Intel XScale processor PXA270 is adopted, IPv6 multicast and stream media transport protocol is analyzed, and the newest version Linux and embedded GUI Qtopia are ported to Lied. Then an open source media player named MPlayer for Lied system is ported and optimized, so a video terminal supporting embedded IPv6 multicast and stream protocol is implemented. The ability of the terminal is then tested and analyzed with Video frames in different formats. Finally, by constructing a mobile IPv6 test-bed in which two IPv6 ready stream servers run, the stream function of the terminal is verified.
