IP组播在数字电视信号传输系统中的应用

摘要

The traditional long-distance transmission of digital TV operation mode is based on the SDH network DS3 signal.With the application of the signal source with the TS over IP,it is more conducive for Digital TV signal transmission to use Resilient Packet Ri%传统数字电视长距离的传输调度方式都是采用SDH网络DS3信号,随着TS OVER IP信号源的应用,使用MSTP网络并利用RPR弹性分组环技术组播信号实现数字电视传输,更有利于数字电视信号的传输。
