    Abstract:

    As the rapid development of network communication and multimedia technology, demand of embedded video surveillance devices is also increasing. This paper provides an embedded video server solution, which uses a high robustness and high compression algorithm-H.264, to encode video source and transplants the open-source Live555 as streaming media module which is responsible for receiving external RTSP connection request, packing sound and video data in a RTP way, as well as sending them. In the end, lots of tests have been done by using standard streaming media client VLC, which prove a timely, fluent and better picture/sound quality.
