Abstract: The design approach of a Linux-based embedded MPEG-4 Video Server (EMP4VS) with MPEG-4 Hardware Encoder was studied. The implementation of an EMP4VS was presented from the aspects of hardware architecture, software design, control/video data flow, the QoS mechanism, and client software. The extension of EMP4VS B/S architecture with middleware server was also discussed.

Key words: video server, embedded system, RTP/RTCP protocol, MPEG-4, Linux
