摘要
在各种接入技术使用的家庭网络有线传输媒质中,G.HN技术涉及电源线、双绞线和同轴电缆,能够最大程度地利用已布设的各种线缆,为视频业务的承载提供必要的网络覆盖和接入实体。随着大带宽低延迟业务的发展,家庭网络对超高清(Ultra HD,UHD)业务传输的需求日益突出,G.HN在承载UHD时面临挑战。给出G.HN承载UHD业务时应具备的功能性能规格,并对G.HN的后续发展作出展望。
Power line,twisted pair and coaxial cable are all included in home network cable transmission medium by G.HN.On the network coverage and terminal access level,G.HN provides support for popularity of video service using all kinds of cables that had been arranged.With the development of large bandwidth and low latency services,the demand for transmission of UHD services in the home network has become increasingly prominent and G.HN is facing challenges when carrying UHD services.This paper gives the suggestion for the requirement of G.HN s function and devices’performance.Finally,the future development of G.HN is prospected.
