Session-based watermarking in live IPTV environment
Dmitri Jarnikov, Egbert Westerveld, Jeroen M. Doumen · 2012
Protecting content, distributed over IPTV networks, from being illegally redistributed by legal subscribers requires methods beyond traditional conditional access and digital rights management systems. Adding watermarking techniques allows one to trace the user would an infringement have occurred. In this paper we describe a practical way to uniquely watermark content for each receiving device in a live IPTV environment. Special focus is given to finding a solution that fits into existing IPTV infrastructures.
