Research on Domestic Application and Optimization of DVB-ASI Signal Interface Board in Optical Transport Network

本文主要介绍在OTN光传送网中直接接入传输DVB-ASI信号的工作原理,针对DVB-ASI信号接口板卡在实际应用中所遇到的问题进行分析与研究,以及如何对DVB-ASI信号接口板卡的性能进行优化。本次优化工作实现了DVB-ASI信号直接在OTN光传送网更高质量传输适配的目标,在提高广播电视传输系统集约化水平和有效降低系统成本的基础上,减少了对国外技术的依赖,增强了相关技术的自主可控能力。

This paper mainly introduces the working principle of directly accessing and transmitting DVB-ASI signals in an optical transport network(OTN),analyzes and studies the problems encountered in the actual application of DVB-ASI signal interface boards,and optimizes the performance of DVB-ASI signal interface boards.This optimization work has achieved the goal of higher quality transmission adaptation of DVB-ASI signals in the optical transport network,improving the level of concentration of the broadcast and television transmission system and effectively reducing system costs.It also reduces the dependence on foreign technology and enhances the self-controllable ability of the broadcast and television transmission field.
