摘　　要：基于MSTP以太网专线进行远程视音频传输,是一种结构简单、线路便宜、容易搭建的传输系统。由于MSTP以太网专线的独特设计,点到点的透传方式,容易实现对用户MAC帧点到点的透传,在线路上能独享带宽,业务延迟小,且和其它业务完全隔离,安全性高,这种业务适合广播级视音频信号远程传输的应用。Remote video and audio transmission base on MSTP Ethernet private line is a system featuring structure simple, line cheap and easy to build. Due to the unique design of MSTP Ethernet private line, the point-to-point transparent way is easy to realize the user MAC frame's point-topoint transmission. With the system, user can share the bandwidth alone with small delay and complete isolation with other service. Performances of the system i t it for broadcast video and audio signal remote transmission.
