Patent 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.
