OTN传输在地市广电的应用

Application of OTN Unidirectional Transmission in DVB Signal Transmission

利用近年来主流的OTN传输技术实现DVB信号的远距离传输。同时将OTN单向传输技术及交换机组播强推等技术相结合,拦截DVB数据接收单位发送过来的所有请求,既实现了数据的顺利下传,又保障了DVB前端核心平台的安全。对以上技术进行了详细的阐述,希望能为其他广电单位在实施相关项目的时候提供建议和经验。

In recent years, the mainstream transmission technology OTN is used to realize the long-distance transmission and download of DVB signals. At the same time, for the security of DVB front-end, it combines ONT unidirectional technology and switch broadcasting push technology to intercept all data sent from download units. In this paper, the above technologies are elaborated in detail, hoping to provide suggestions for other radio and television units in the implementation of related projects.
