The Research On The Integration Of Telecom,TV And Internet Networks Of The Catv Full-service Network Construction Model And Its Implementation

In three Network convergence situation,the broadcast networks after digitaltransformation, already have the basis to the development of full-service network. Inaccordance with the spirit of the executive meeting of the State Council in2010, thecable industry and the telecommunications industry in2010-2012will be to carry outtwo-way pilot from2013to2015, the full realization of the development of triple play.Broadcasting, telecommunications market structure separate operation is about tocease to exist, in this situation, the radio and television operators how to own cableTV network to transform and turn into a full-service network platform became thedevelopment of cable network operators direction. Obviously, how to build aQuanchengquanwang, manageable and controllable network operators to provideinteractive video and data services, from providing a purely broadcast-TV business,transforming into one of the most important aspect is the construction Cablebidirectional network. This paper studies the full-service platform, the basis of opticalnetwork and several two-way network transformation model and its implementationsin Hunan Cable, the work done mainly include the following aspects:First, the research and analysis on a variety of cable-way network structure, tostudy the existing two-way network upgrade mode, through a comparative study of asuitable construction of Hunan wired network upgrade ideas;Second, the development of various types of value-added services, needs analysis,and so on LAN, CMTS, xPON network upgrade model network construction, analyzetheir respective advantages and disadvantages based the FTTx xPON two-waynetwork transformation model, its key the technology for the analysis.Third, to study the current HFC network status, proposed1550systemEPON-based video-on-demand business platform building programs, and EPONnetwork proposed the two baseband the EOC and modulation EOC establishednetwork model and modulated EOC four mainstream technologies (HomePlug,HomePNA, MOCA, WiFi) to do the analysis, EPON LAN and EPON EOC model,and on this basis to establish two model scenarios;Fourth, based on EPON technology model, for Hunan Cable network, carried outthe detailed design and Yongzhou Blue Mountain cable network, for example,elaborated the design implementation process.
