This paper chiefly introduces the model of Video Conferencing System, H.323 standard
of ITU-T and RTP/RTCP protocol, and realizes a WAN-Oriented Video Conferencing
System—VCSW (Video Conferencing System on WAN). In VCSW, RTP/RTCP protocol is used for transporting media data and video conference on WAN can be established, so VCSW has abroad application scope. This paper stresses analyzing RTP/RTCP protocol, realizes it and modifies some details of it according to our device condition: reduces some fields of RTP and RTCP header, removes some information managed by RTP/RTCP. Consequently in testing of lab, good effect is achieved.
Keywords: Video Conferencing System on WAN (VCSW); Real-time Transport Protocol (RTP); Real-time Transport Control Protocol (RTCP); RTP Session; Multipoint Control Unit (MCU)
