IPTV系统中的视频记录是一种有前途的服务，其提供与更靠近诸如机顶盒的用户设备存储TV内容有关的时移服务。现有的方法不支持具有相关内容的节点之间的协作，这一事实可能影响整个系统的性能。为了使这项服务更具互动性和主动性，本文提出了一种新的基于性能的IPTV内容共享网络，使用智能个人信息网络（智能PIN）的架构，它使用以用户为中心的实用程序为基础的多媒体数据复制方案（MDRS）。这允许基于网络性能和用户对所交换的多媒体内容的兴趣来交换数据，以便实现高效的内容共享。所提出的解决方案进行了评估，通过广泛的模拟和结果表明，与其他两个现有的通用数据复制方案相比，大大改善了行为。
Video recording in IPTV systems is a promising service that provides time-shifted services in relation to storing TV content closer to user devices such as set-top boxes. Existing approaches do not support collaboration between nodes which have correlated contents, a fact that can affect the performance of the overall system. To make this service more interactive and proactive, this paper presents the architecture using the smart personal information network (Smart PIN) as a novel performance-based content sharing network for IPTV content which uses a user-centric utility-based multimedia data replication scheme (MDRS). This allows the exchange of data based on both network performance and user interest in exchanged multimedia content in order to achieve efficient content sharing. The proposed solution is evaluated through extensive simulations and results show much improved behavior in comparison with two other existing general purpose data replication schemes.
