摘要
以"传送与节目分离、业务提供与用户驻地分离"的建网理念构建的下一代有线数字电视网络,由骨干网到用户驻地网每用户最少需要42Mbit/s的速率,能以什么样最有效的技术把用户园区和骨干网连接起来,是本文主要讨论的问题。
The construction of next generation Cable Digital TV network is based on the ideal of ＂transmission and program separation, the business provide and customer premise separation＂. One customer at least needs 42 Mbit/s from the Backbone net to Customer Premise Network. How to connect the customer area with the back-bone network most effectively is the problem that this paper mainly discusses.
