摘要
针对Web网络协同产品设计过程网络会议的需求,分析流媒体传输与控制技术、JMF媒体框架技术,研究RTP/RTCP流媒体传输与控制协议和JMF RTP编程机制,建立类B/S结构的系统框架和基于时间戳的RTCP流媒体同步机制,开发基于JMF类B/S结构的网络视频会议系统,实现总体设计、客户浏览器设计以及与PDM系统的集成。
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.
