【摘要】：随着网络多媒体技术的飞速发展,互联网上的多媒体应用层出不穷。IPTV业务是基于IP宽带网络的电视广播业务,作为一种新兴的互联网业务,为运营商提供了新的商业价值。IPTV业务对IP网络提出了很高的要求,如高带宽、实时、高质量等要求。其技术实现难点是：如何接入直播电视节目?如何在有限的IP网络带宽下,为用户提供尽可能高画质、低抖动、可管理的电视节目?这将对IPTV的编码技术、IP承载网络的承载能力、全网的组播能力提出相当大的挑战。本文的研究正是从这几个方面出发探讨这些问题。宁夏IPTV系统全国首创性与宁夏广电合作,接入宁夏广电直播节目,形成独特的“宁夏模式”,为IPTV节目内容运营提供了新的运营方式。为了更好的实现IPTV业务运营,本文首先设计了宁夏IPTV的业务特性和系统结构以及对承载网络的带宽和安全需求,结合目前宁夏电信互联网现状,对现有的IP城域网提出了改造方案并实施改造,解决了全网组播单播业务混合部署、组播复制点设置等问题。其次,本文还对IPTV系统融合手机电视业务以及户外电子广告业务进行了详细的组网方案说明。通过对IPTV系统的升级改造,确保IPTV业务在承载网中可靠运行的同时,为电信手机用户提供手机电视业务,户外LED大屏提供集约化的广告管理业务,为IPTV系统融合新业务提供了有益参考。最后本文针对未来IPTV系统发展做了探讨,指出了IPTV业务今后大规模开展后,必须对IPTV承载网及时调整,对IPTV的安全和稳定都具有十分重要的意义。
[Abstract]:With the rapid development of network multimedia technology, multimedia applications on the Internet emerge in endlessly. IPTV services are television broadcasting services based on IP broadband network, as a new kind of Internet services. IPTV provides operators with new business value. IPTV services put forward very high requirements for IP networks, such as high bandwidth, real-time, high quality and so on. The technical difficulties are: how to access live TV programs? How to provide users with the highest quality, low jitter and manageable TV programs under the limited IP network bandwidth? This will pose a great challenge to IPTV coding technology and IP bearer network's carrying capacity and the whole network's multicast capability. The research of this paper is from these several aspects to discuss these problems. Ningxia IPTV system is the first in China to cooperate with Ningxia Radio and Television to connect with Ningxia Radio and Television Live Program, forming a unique "Ningxia Mode", which provides a new operation mode for IPTV program content operation. In order to better realize IPTV service operation, this paper first designs the service characteristics and system structure of Ningxia IPTV, and the bandwidth and security requirements of carrying network, combining with the current situation of Ningxia Telecom Internet. The existing IP metropolitan area network (IP man) is reformed and implemented, which solves the problems such as the mixed deployment of multicast unicast services and the setting of multicast replication points. Secondly, the IPTV system integrated mobile TV service and outdoor electronic advertising service are described in detail. The IPTV system is upgraded to ensure that the IPTV service can run reliably in the carrying network, and at the same time, it can provide mobile TV service for the telecom mobile phone users, and provide intensive advertising management service for the outdoor LED large screen. It provides a useful reference for IPTV system to integrate new services. Finally, this paper discusses the development of IPTV system in the future, and points out that after the large-scale development of IPTV service in the future, it is necessary to adjust the IPTV carrier network in time, which is of great significance to the security and stability of IPTV.
