IPTV或基于互联网的电视广播将显著改变人们获取信息、娱乐以及相互协作的方式。与现在的电视系统相比，IPTV给观众更多的选择，看什么和如何看，并允许用户轻松地播放自己的节目，从而“民主化”的信息广播。然而，要实现IPTV的愿景，有许多具有挑战性的问题，如基于内容的频道发现和选择，用户视图定制，和高效的媒体流。这份立场文件描述了未来IPTV系统的框架，数百万观众可以选择多个频道，以定制的方式观看，并以对等的方式相互合作，以提供电视节目。
IPTV, or Internet-Based TV broadcasting is going to significantly change the way people obtain information, get entertainment, and possibly collaborate with each other. Compared with today’s TV system, IPTV gives the viewers more choice as to what to watch and how to watch, and allows users to broadcast their own programs easily, thus “democratizing” information broadcasting. To realize the vision of IPTV, however, there are many challenging issues, such as content-based channel discovery and selection, user view customization, and efficient media streaming. This position paper describes a framework for future IPTV systems where millions of viewers can select multiple channels, view them in a customized way, and cooperate with each other in a peer-to-peer fashion for TV program delivery.
