Abstract

An anti-piracy system introduces distortion (204) into a recorded image, while maintaining a high quality projected image. The video source material includes modulated entities for providing artifacts incompatible with the content of the video source material and selectively deliverable information that the projection system uses to demodulate the entities. A projector receives the information about the modulated entity and corrects, or demodulates, the entity (210). The projection system (208) also imposes a recording device dependent interference on the projected images.
