Motion picture encoding and counterfeit tracking system and method |
摘要 |
Information is incorporated into motion picture film prints in the form of images or patterns that appear as unobtrusive defects or artifacts. The unique codes are used in association with the print number of the film and are reproduced in video copies of the film made by counterfeiters. This code can be read from the counterfeit copy and can be used to trace the source of the counterfeit. The digits of the print number are recorded in separate frames to increase the difficulty to counterfeiters in detecting and deleting them.
