Use of “Emergable Watermarks” as Copy Indicators for Securing Video Contentthe video had been illegally copied, and distort the image quality. Testing of a prototype implementation demonstrated the effectiveness of this method. The peak-signal-to-noise-ratio in watermarked video was adjustable by more than 28 dB. Use of this method should help deter the illegal copying and/or distributing of copyrighted videos.
