"This week, Justin.tv is rolling out new measures to protect copyrighted live video streams from being pirated on their site. The technology the company is using will allow them to remove pirate channels without having to issue a takedown notice first.

Using technology from Vobile, an online video publishing company, Justin.tv partners (including FOX), will be able to use VideoDNA™ "fingerprinting" technology to watermark their digital content. If the content is spotted elsewhere on the site, Justin.tv will automatically remove the infringing channel. Think of it as DRM for real-time, streaming media."
