This document considers the consequences of moving the underlying network architecture to an Information-Centric Network (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, covering a wide range of scenarios: we look at how to evolve DASH to work over ICN, and leverage the recent ISO/IEC MPEG Dynamic Adaptive Streaming over HTTP (DASH) standard; we consider layered encoding over ICN; P2P mechanisms introduce distinct requirements for video and we look at how to adapt PPSP for ICN; IPTV adds delay constraints, and this will create more stringent requirements over ICN as well. As part of the discussion on video, we discuss DRMs in ICN. Finally, in addition to consider how existing mechanisms would be impacted by ICN, this document lists some research issues to design ICN specific video streaming mechanisms.
