本文档考虑了将底层网络架构从当前的互联网迁移到信息中心网络（ICN）架构对视频分发的影响。由于未来网络中的大部分流量预计将是视频，我们考虑如何修改现有的视频流传输机制。介绍了在ICN上进行视频分发的几个重要问题。所涵盖的各种情景包括：发展HTTP上的动态自适应流（DASH）以在ICN上工作并利用最近的ISO/IEC运动图像专家组（MPEG）标准，在ICN上分层编码，使用对等（P2P）机制引入对视频的不同要求，使对等流协议（PPSP）适应ICN，由于互联网协议电视（IPTV）增加的延迟约束，对ICN产生了更严格的要求，并在ICN中管理数字权利。最后，除了考虑现有的机制将如何受到ICN的影响，本文列出了一些研究问题，以设计ICN特定的视频流机制。
This document considers the consequences of moving the underlying network architecture from the current Internet to an Information- Centric Networking (ICN) architecture on video distribution. As most of the traffic in future networks is expected to be video, we consider how to modify the existing video streaming mechanisms. Several important topics related to video distribution over ICN are presented. The wide range of scenarios covered includes the following: evolving Dynamic Adaptive Streaming over HTTP (DASH) to work over ICN and leverage the recent ISO/IEC Moving Picture Experts Group (MPEG) standard, layering encoding over ICN, introducing distinct requirements for video using Peer-to-Peer (P2P) mechanisms, adapting the Peer-to-Peer Streaming Protocol (PPSP) for ICN, creating more stringent requirements over ICN because of delay constraints added by Internet Protocol Television (IPTV), and managing digital rights in ICN. Finally, in addition to considering how existing mechanisms would be impacted by ICN, this document lists some research issues to design ICN-specific video streaming mechanisms.
