摘要
介绍了SDH的帧结构和基本复用原理，在此基础上，探讨了视频信号在SDH上的传输技术。文章详细叙述了2．048Mbps的电视会议信号、34．368Mbps的视频信号和8Mbps的MPEG－2传输流复用映射进SDH帧结构的方法；SDH数字复用设备的组成和原理；最后介绍一个具有SDH接口的MPEG－2多媒体系统终端机设计实例。
Transmission network is trending to SDH (Synchronous Digital Hierarchy)mainly basis on optical fabric. In this paper, SDH frame structure and basic multiplex principle are introduced firstly. Afterwards, transmission technique of video signal on SDH, especially the multiplex and mapping methods of 2. 048Mbps video conference signal.34. 368Mbps video signal and SMbps MPEG-ⅡTS signal is studied in detail. Finally, SDH digital multiplex device is introduced.
