Based on requirement of real-time network video conference for computer supported collaborative product design in Web environment, a pure software multi-user video conference system of the similarity B/S structure was developed. JMF (Java media framework) was adopted to achieve system development. Transmission and control of multimedia data were implemented by the streaming media technology of transport and control in conference process. By way of using real-time transport protocol (RTP) and real-time transport control protocol (RTCP), the performance and quality of conference data streams were dynamic monitored. Streaming media reception and send services of conference process were achieved by programming mechanisms of JMF RTP. Based-on Java Bean, Servlet and Applet program design languages, the system framework and client browser program design were completed, integration with product data management (PDM) system was implemented. The system provides a multimedia supporting platform for knowledge exchange and sharing in collaborative design process.
