The Research On Bearing Capacity Of IPTV Based On MAN

The vigorous development of broadband wins opportunities for the IP network operators. Just because of the broadband, various applications such as video, game, stock and electric business become unprecedented brilliancy.For the purpose of seizing the opportunity, the IP network operators have to build a high-efficient broadband value-added service to support platform. On one hand, the platform can appeal to the operators who have various value-added service deliver service on it. On the other hand, the platform can provide the users with a bridge for receiving service easily. Therefore, IPTV service, as a charge value-added service, has possessed the marketing condition.IPTV video broadcast system is mainly based on the Multicast technology and IGMP protocol which exist for a long time, providing management structure and software structure design on account of the actual situation of the IP metro network and the operating demand of the operators. In this way, the system resolves theoretically the technical problems and management issues of the video broadcast from the center to the client.IPTV:Actually, it delivers clear TV program through broadband multimedia. The quality of image and sound, much higher than that of the current cable TV, can achieve the effect of DVD surround sound or even the AC-35.1 track effect. Moreover, the number of channels is more than the traditional cable TV, for example, the traditional cable TV can deliver about 70 analog channels whereas the broadband multimedia can deliver at least more than 200 DVD-qualified digital TV programs.Under the trend of "triple-play", the application of voice, data and media can be offered by one IPTV operator, which means to the customers that the focus has transferred to the cost performance of the provided service. By summarizing the global experience of popularizing IPTV, comparing the differences among the government regulation, industry competition, technology and the current service, and analyzing the advantages and disadvantages of the competition of telecom operators and Cable TV Companies, the develop strategy is being discussed and the competitive strategy is being worked out.This article includes mainly the following content:1. Research Background:Introduce the current background and relevant protocol standard of IPTV technology.2. Research Status:Introduce briefly the current access based on the means of "IP STB+TV", and the Authentication Method is PPPOE or DHCP. Explain the important parameters and demands of IPTV carrying network in details and then analyze deeply the reform and construction procedures and scheme of IP metro carrying network.3. Research Scheme:Explain overall content and initial assumption, including some different IPTV network modes.
