电视消费者喜欢互动性和个性化。互联网协议电视（IPTV）系统通过提供包括视频点播（VoD）、网络个人视频记录（NPVR）和时移TV（TSTV）的不同服务来帮助满足这种期望。然而，这些服务由于需要针对每个活动客户的单播视频流而在网络上施加了沉重的业务负载。本文讨论了通过在网络中引入存储来减少网络流量负载的方法，从而避免了在城域网或核心网上支持单播流量的需要，以及将内容智能地放置在这些存储设备上的算法。描述了一种用于智能再分发的算法，该算法努力将最合适的内容放置在消费者附近。本文进一步讨论了这种新的网络存储模式如何有助于提高IPTV消费者的体验质量，并有助于部署互联网视频和共享用户生成的内容（UGC）。
Television (TV) consumers adore interactivity and personalization. Internet Protocol television (IPTV) systems help satisfy this desire by providing different services including video-on-demand (VoD), network personal video recording (NPVR), and time shift TV (TSTV). However, these services place a heavy traffic load on the network by requiring a unicast video stream for each active customer. This paper discusses means to reduce the network traffic load by introducing storage deep in the network—thus avoiding the need for unicast traffic support over the metro or core network—and algorithms to place content intelligently on those storage devices. An algorithm for intelligent redistribution is described that endeavors to place the most appropriate content close to consumers. The paper discusses further how this new paradigm of network storage can help improve quality of experience for the IPTV consumer and can assist in the deployment of Internet video and sharing of user-generated content (UGC).
