摘　　要：介绍了基于MPEG-4硬件实时编码器的嵌入式流媒体服务器的设计,阐述了系统的硬件组成,并从MPEG-4视频流封装、RTP/RTCP协议实现、开源RTSP协议库的应用和Web服务器的构建等方面介绍了软件系统的具体实现过程。此外,还对实时传输中所涉及的时间戳和QoS机制的实现方法进行了介绍。实验结果表明,该系统具有丢包率低和容错能力强等特点,适用于移动视频监控等实际应用场合。An embedded streaming media server design based on the MPEG-4 real-time hardware encoder is presented, The construct of the system hardware is explained. And the sottware system realization process is indicated on the several aspects of MPEG-4 video streaming package, RTP/RTCP implementation, open source RTSP protocol library and web server application. In addition, the timestamp and QoS mechanism for the implementation method in the real-time transmission is introduced, Experimental results show that the system can achieve low-loss rate and preferable fault-tolerant capability, and it can be applied to mobile video surveillance and other practical applications.
