目前,我省各县已基本开通采用数字技术的光缆干线,实现了全省、全市范围内的联网。同时,我县有线数字电视实现了全覆盖:光纤同轴电缆混合网(HFC)以光纤为干线、同轴电缆为分配网的接入网。在平常的工作中,我们对于有线数字电视网络的现状与管理,遇到了一些实际问题。为了进一步完善有线数字电视网络的传输质量与管理,试以本文做一探讨,供参考。
At present, all counties in our province have basically opened optical fiber trunk lines using digital technology and realized networking within the province and the whole city. At the same time, my county wired digital TV to achieve full coverage: fiber coaxial cable hybrid network (HFC) to fiber as the trunk, coaxial cable distribution network access network. In normal work, we have encountered some practical problems with the status quo and management of cable DTV networks. In order to further improve the transmission quality and management of cable digital television network, try to do a discussion of this article for reference.
