摘　　要：目前,IPTV技术还存在服务效率低、重定向机制复杂、网络需要更高带宽、资源调度不灵活等问题。为了更好地满足IPTV业务发展的需要,有必要引进一种更为先进的IPTV网络架构。在介绍了IPTV技术和P2P对等计算技术基础上,提出了一种基于超级节点的P2P-IPTV系统的设计方案,给出了基于超级节点的P2P-IPTV体系结构,并介绍了基于该体系结构的P2P-IPTV系统原理。At present,problems of low services efficiency,complexity in re-direction mechanism,needs of higher bandwidth,no agility in resources scheduling,still exist in IPTT technology.To better meet the need of IPTV oper- ation development,an advanced IPTV networks frame should be introduced.After the presentation of IPTV and P2P technology,a solution of super node based P2P-LPTV system was put forward,including the architecture and the principle of system based on the structure.
