数字电视双向网络HFC优化方案设计与实施

Design and Implementation of HFC Optimization Scheme for Digital TV Bidirectional Network

深入研究网络基础建设环境、系统运行功能以及传输网络部署等基本情况,设计了一种新型的数字电视双向网络混合光纤同轴电缆(Hybrid Fiber Coax,HFC)组织架构,并通过中国电缆数据服务接口规范(China-Data Over Cable Interface Specifications,C-DOCSIS)实现对各级多路播出平台和终端设备的智能监控,全面提升了系统运行效率,降低了噪声与干扰等信号对源信号的影响,并为对接5G通信技术应用打下坚实基础。

This paper deeply studies the network infrastructure environment,system operation functions,transmission network deployment and other basic conditions,designs a new type of digital TV two-way network Hybrid Fiber Coax(HFC)organizational structure,and realizes intelligent monitoring of multi-channel broadcasting platforms and terminal equipment at all levels through China-Data Over Cable Interface Specifications(C-DOCSIS)technical specifications,comprehensively improves the system operation efficiency,reduces the impact of noise and interference signals on source signals,and laid a solid foundation for the application of 5G communication technology.
