随着信息技术的不断发展,多媒体应用越来越普及,广播电视也越来越向智能化方向发展,人们对VOD点播、视频会议、远程医疗、远程办公、远程教学等有了更多的需求,这就需要以更快的网络带宽速度为前提,因而将双向HFC网络技术应用于广电数据通信网络中就具有重要的现实意义。本论文分别从双向HFC网络技术的应用要求和双向HFC网络改造方式两个方面展开论述,探讨了其在完善广电数据通信网络中的应用。
With the continuous development of information technology, multimedia applications are becoming more and more popular. Radio and television are also becoming more and more intelligent. There is an increasing demand for VOD, video conferencing, telemedicine, telecommuting and distance learning , Which requires a faster network bandwidth as a prerequisite, so the two-way HFC network technology used in radio and television data communications network has important practical significance. This paper discusses the application requirements of bi-directional HFC network technology and the way of bi-directional HFC network transformation respectively, and discusses its application in the improvement of broadcasting and television data communication network.
