Abstract: Anti-piracy measures for stereoscopic 3D content media displayed in dual lens projection systems are achieved by the forensic marking of each image in a stereoscopic image pair with separate component forensic marks or dots associated with each image of an image pair. In one example, the component mark used for marking one image of the pair is identical to the component forensic mark used for marking the other image of the pair. In another example, the component marks are different from each other. When superimposed over each other in proper alignment, the two component marks form a composite forensic mark. In this latter example, they each lack one or more of the forensic dots or shapes existing in the composite mark, and the component marks may or may not have one or more corresponding forensic dots or shapes in common.

Abstract: A method and system are disclosed for archiving video content to film and recovering the video from the film archive. Video data corresponding to the content and a characterization pattern associated with the data are provided as encoded data, which is recorded onto a film for producing a film archive. The characterization pattern contains spatial, temporal and colorimetric information relating to the video data, and provides a basis for recovering the video content from the film archive.

Abstract: A method and system are disclosed for archiving video content to film and recovering the video from the film archive. Video content and a characterization pattern associated with the content are provided as encoded data, which is recorded onto a film and processed to produce a film archive. By encoding the video data using a non-linear transformation between video codes and film density codes, the resulting film archive allows a film print to be produced at a higher quality compared to other film archive techniques. The characterization pattern contains spatial, temporal and colorimetric information relating to the video content, and provides a basis for recovering the video content from the film archive.
