Under NGB Mode The Optimization And Application Program Of The Cable TV Network In Xi’an

Currently existing cable television network, because there is no a unified standard of mature, the domestic various provinces and cities of the cable TV network construction in oneself fumble, relatively northwest catv two-way process in China is relatively slow.As the capital city of northwest China, Xi’an is important in the background of the country to accelerate the pace of triple play and face the competition from other network operators. How to optimize the existing cable network to meet the next generation of broadcast television networks (NGB) building requirements, giving users a more convenient and efficient application experience while reducing their costs to speed up the construction pace of structural reform and improving network competition in the industry force out a suitable route, Xi’an broadcasting their technology is particularly urgent and important. Combined with two-way cable network in Xi’an stage in the construction process of transformation emergent problems and my several years experience in industry, lessons learned and the future direction of development thinking cable research,so I chose the topic of this paper.This paper is a summary of historical experience, to explore the domestic and international trends in optical access network technology, based on the analysis of the actual characteristics of the cable TV network in Xi’an, compared to the current mainstream network technology, in conjunction with their work summed up in Xi’an Cable bidirectional network problems in the construction process, Xi’an cable backbone ring network, metro and access network status quo and make feasibility analysis overview and system optimization, and technology demonstration area west of Ham District as a pilot project in while its network needs analysis and feasibility analysis of the network, give specific recommendations and intelligent network technology to optimize two-way design, built to meet future diverse business network. Proposed smart home concept, design, interactive on-demand IPQAM based networking solutions, building Quanchengquanwang manageable and controllable network management system, intelligent terminal application deployment. Make the network cable to meet future application requirements, competition and self-confidence to deal with the challenges of the industry.
