摘要：
海量信息存储与检索一直是基于IPTV的网络影视系统的重要问题。针对现有系统的不足，提出了一种新型的网络影视存储系统，给出了该系统的模型及实现方法。该系统采用对等存储模型以及热点处理机制提高系统的存储效率；同时，该系统采用基于分布式哈希表的对等搜索方法提高影片的检索效率，并提供透明的用户接口。较之传统系统，该 该系统具有较高的存储效率及检索速度。
关键词: IPTV 网络影视 对等存储模型 热点扩散 分布式哈希表
Abstract:
Mass information storage and retrieval has been an important issue of the network video systems based on IPTV. Aiming at the disadvantages of traditional systems, a novel network video storage system is proposed. And the model and its implementation method are given. The system adopts a P2P storage model and the hotspot processing meehanism to improve storage efficiency. Based on a distributed hash table, the system utilizes a P2P retrieval method to accelerate film searching and so on. And a transparent client interface is given. Compared with the traditional systems, this one is efficient and fast
Key words: IPTV, network video, P2P storage model, hotspot anneal, distributed hash table （DHT）
