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.
