Wireless CDN video streaming architecture for IPTV

Abstract__ Wireless IPTV (Internet Protocol TeleVision) aims to make the traditional IPTV
and related services available to users anywhere, anytime, on any device, and through any
network. Mobile streaming TV is one of the alternatives to deploy such a system; others are
DVB-H or MediaFLO. In this paper we propose an alternative CDN-based architecture to
distribute contents to different access networks, in order to create a triple screen platform.
The core elements of the system are the video streamers, acting as surrogates of the mobile
CDN-based architecture, installed in the access networks (including mobile), and the
transcoding servers in the premises of the content providers. The paper focused on the
wireless part of the system, analyzing the architecture and performance results related with
the video coding and the efficiency obtained due to the placement of the streaming servers.
The system has been deployed by a Spanish media company for its use with different
Telcos, ISPs and media companies.
