  • Film fingerprinting
    Patent number: 8060942
    Abstract: A technique for film marking includes coding a print identifier into a binary-coded serial number; identifying particular frames (bit frames) that will be used to convey the bits (binary digits) of the binary-coded serial number and marking these bit frames in accordance with the particular bit values of the binary-coded serial number. The presence of a predefined mark on a bit frame is representative of a binary digit having a value of one, while the absence of the predefined mark on a bit frame is representative of a binary digit having a value of zero.
    Type: Grant
    Filed: April 27, 2004
    Date of Patent: November 15, 2011
    Assignee: Thomson Licensing

  • Film fingerprinting
    Patent number: 7979710
    Abstract: A technique for film marking includes coding a print identifier into a binary-coded bit-complement serial number; identifying particular frames that will be used to convey the bits of the binary-coded bit-complement serial number and marking these bit frames in accordance with the particular bit values of the binary-coded bit-complement serial number. The presence of a predefined mark on a bit frame is representative of a binary digit having a value of one, while the absence of the predefined mark on a bit frame is representative of a binary digit having a value of zero.
