摘要
IPTV是一种集互联网、多媒体、通信等多种技术于一体的全新系统,在从内容制作到终端接收的整个实现过程中,涉及到包括编码、数字版权管理、内容分发网络、机顶盒等许多关键技术,本文对这些关键技术进行了详细介绍和分析,并针对现有IPTV集中交换模式的缺陷,提出了基于集中式P2P技术的IPTV系统,提高了IPTV服务质量和系统性能。
IPTV is a new system that integrates internet, multimedia communication and other kinds of technologies. This paper describes the architecture of IPTV system, and analyzes the key technology of content creation, content integration, content transmission, and IPTV terminal. The IPTV system based on concentrated P2P technology is also proposed to overcome the flaw of the concentrated exchange pattern in existing IPTV. It is believed that the new system will effectively improve the quality of service and performance. IPTV is moving rapidly towards massmarket adoption. The involvement of incumbent telecoms operators in most major markets by 2007 will provide the marketing, word-of-mouth and - for the many conservative-minded television viewers yet to switch to digital TV - the credibility that could boost the market for all IPTV providers.
