基于外交互式的双向CATV网络系统

External Interactive Two-way CATV Network System

分析单向CATV网络不能进行双向交互的原因 ,提出建立上行外交互式通道的方法实现单向CATV网络向双向交互式网络的改造 ;分析Internet网络上下行数据流量的特点 ,说明外交互式网络正好适应于Internet网络数据传输 ;介绍常见的几种外交互式辅助网络的类型 ,最后以电力线外交互网络为实例 。

This paper has analysed the reason that one way CATV network can’t carry on the two way interactive,proposed transforming one way CATV into two way interactive network by setting up upload external interactive channel,analysed the characteristic of the data flow of the Internet network from upload to download,introduced the characteristic and types of the external interactive network,finally took network outside the power line as an instance,described the realization course of the external interactive.
