Radio over IP传输系统的架构和规范 |
随着有线电视网向深度光纤或光纤到户(FTTH)架构的迁移,现在更容易提供双向高质量的媒体服务,而这需要非常高速的数字传输各种高质量的内容。由于有线电视网通过在头端和电缆调制解调器(CM)之间传输射频(RF)信号来提供服务,因此需要为传输RF信号对有线电视网的配置和设备进行优化。为了迁移到使用全光纤接入的有线电视,建议通过新的网络设备来改变服务运营商(SO)现有网络设备,且服务运营商通过基于HFC的有线电视网来提供广播服务和各种数据服务。因此,需要一种高效费比的解决方案,以可部署、可接受的方式迁移到基于光纤的有线电视网。本[新]建议书草案提供了一种高效费比的解决方案,以使基于HFC的有线电视网设备适应基于光纤的有线电视网设备。RoIP系统旨在发射基于电缆数据传送服务接口规范(DOCSIS)的上行流(US)有线调制解调器RF信号至有线调制解调器终端系统(CMTS),其使用的媒介为有线光纤电视网的IP传输。 |
