河北广电网络 IP数字电视传输系统的设计与应用

摘要

根据数字电视传输系统的现状，结合河北广电网络的特点，规划和设计符合实际情况的数字电视综合传输系统。该系统在省干DWDM网和数据网的基础上，采用IP技术，实现了主备两路同时传输。结合现有的数字电视传输系统，充分考虑IP系统所具有的优势和不足，克服了传统系统的缺点但保持了它的稳定可靠性。%Based on the current situation of the domestic digital TV transmission system,this paper combines the characteristics of Hebei radio and television network and aims to plan and design the digital TV integrated transmission system.This system adopts IP Technology on the basis of the DWDM net and data network as a way to realize two-way simultaneous transmission at the same time.Considering the existing digital television transmission system,the advantages and disadvantages of IP system have been taken into consideration.There-fore,it overcomes the shortcomings of traditional systems and still maintains its stability and reliability.
