Status Under The Triple Play Iptv In China Unicom Network Design

"Triple play" is the community for many years been a focus of attention and focus, but also people the information and network development of a vision and expectations.With the "triple play" the continuous progress of the process, China has basically met the conditions for further development of triple play technology, network infrastructure and market space, speed up network convergence has entered a crucial period.With the official launch of pilot triple play, IPTVnetwork construction of China Unicom has entered a rapid development period.Broadband telecommunications network using IPTVservice platform, set the Internet, multimedia, communications and other technology, and to set-top box or other audio and video codecs with the ability of digital devices for the terminal, by aggregating a variety of SP content and value-added streaming media services applications, including digital television to provide users with a variety of interactive services including brand-new technology.It is well adapted to the current trend of rapid development of the network, full and effective use of network resources.IPTV's main selling point is the interaction, and the Inter net business expansion.IPTVcan also be very easy to the television services and Internet browsing, e-mail, and a variety of online information consulting, entertainment, education and business functions together in the future competition in a dominant position.IPTVis a new technology evolved in the industry, it will profoundly change people's entertainment and lifestyle, and herald a new and huge markets.However, the introduction of new technologies, new business, but also to system design, network organization, coding standard selection and so bring greater flexibility and complexity.The IPTVas a new business in China Unicom is currently no proven network design specification, there are some aspects of networking problems.This paper is in the research in Beijing, Heilongjiang, Shanghai, Liaoning and other provinces of the IPTVsystem construction experience, IPTVsystems for how the different network environment of networking.This paper from the IPTV, networking, implementation, and provides business, coding standards, system security, user access, network performance and network cases, etc., for the networking technology in the discussion.Hope that through this article, IPTVnetwork construction can provide a reference.
