Abstract: Based on requirement of network conferences for networked collaborative product design processes in Web environment, transmit and control technology of streaming media and Java Media Framework(JMF) technology are analyzed, Real-time Transport Protocol(RTP) and Real-time Transport Control Protocol(RTCP) and mechanism of JMF RTP programming are discussed. System infrastructure of similarity Browser/Server(B/S) structure and streaming media synchronization mechanism based on timestamp are put forward, video conference system of similarity B/S structure is developed based on JMF, system framework design and browser design of client-end are realized, and integration with Product Data Management(PDM) system is implemented.

Key words: collaborative design, network video conference, similarity B/S structure, system integration
