Abstract :
Camcorder piracy has great impact on the movie industry. Although there are many methods to prevent recording in theatre, no recognized technology satisfies the need of defeating camcorder piracy as well as having no effect on the audience. To realize anti-piracy, we uses a new paradigm of information display technology, called temporal psychovisual modulation (TPVM). TPVM exploits the difference in image formation mechanisms of human eyes and imaging sensors. Based on this difference, we build a prototype system on the platform of DLP® LightCrafter 4500™ which features high speed pattern display. The display system serves as a proof-of-concept of anti-piracy system.
