【摘要】： IPTV业务是基于电信宽带网络的宽带业务平台,以机顶盒或其它具有音视频编解码能力的数字化设备为终端,通过聚合SP的各种流媒体服务内容和增值应用,为用户提供多种互动多媒体服务的一项业务。IPTV业务主要有广播、点播、时移电视、信息服务、视频通信、互动游戏、消息服务、音乐、卡拉OK/MTV、远程教育、互动广告、个人定制录像、互联网浏览等。它是一种新型电视传播形式,填补了宽带视频应用方面的空白。用户可以随意点播,成本低廉,一旦形成规模,将带来极大的利益。IPTV是一场新技术演变出来的产业,它将深刻改变人们的娱乐和生活方式,预示着一个及其巨大的新市场产生。 在我国国内,IPTV业务也已取得相当大的发展。尤其是在上海,由于上海电信和上海文广的通力协作,截至2007年末,上海的IPTV的用户数已经超过了30万,展示了良好的市场发展潜力。 然而,新业务新技术的引入,也给系统设计、网络组织等都带来了更大的灵活性和复杂性。而IPTV作为一项新兴业务,在业界目前尚没有成熟的网络设计方面的规范,导致了相当多的组网问题。 本论文就是在调研了上海、浙江、江西、广西、海南等省的IPTV系统建设经验之后,针对如何进行IPTV系统在不同网络环境下组网的研究。本论文从IPTV的组网方式、提供的业务及实现方式、编解码标准、系统安全、用户接入方式、网络的性能指标及组网案例等方面,对于组网技术进行了研讨。希望通过本论文,能够为IPTV网络的构建提供一定的参考。
[Abstract]:IPTV service is a broadband service platform based on telecommunication broadband network, with set-top box or other digital equipment with audio and video codec as the terminal, by aggregating all kinds of streaming media service content and value-added application of SP, IPTV services mainly include broadcast, on-demand, time-shift television, information services, video communications, interactive games, messaging services, music, karaoke / MTV, distance education, interactive advertising, Personal customized video, Internet browsing, etc. It is a new form of television transmission, filling the gap in broadband video applications. Users can be on demand at will, low cost, once formed, will bring great benefits. IPTV is a new technology evolved from the industry, it will profoundly change people's entertainment and lifestyle. It heralds the emergence of an extremely large new market. In our country, IPTV business has also made considerable development. Especially in Shanghai, as a result of the collaboration between Shanghai Telecom and Shanghai Wenguang, by the end of 2007, the number of IPTV users in Shanghai had exceeded three hundred thousand, showing a good market potential. However, the introduction of new business and new technology has brought more flexibility and complexity to system design, network organization and so on. As a new business, IPTV has no mature specification in network design, which leads to a lot of networking problems. After investigating the experience of IPTV system construction in Shanghai, Zhejiang, Jiangxi, Guangxi and Hainan provinces, this paper studies how to construct IPTV system under different network environment. In this paper, the networking technology is discussed from the aspects of the networking mode of IPTV, the service and realization mode, coding and decoding standard, system security, user access mode, network performance index and networking cases, etc. It is hoped that this paper can provide some reference for the construction of IPTV network.
