Method and apparatus for uniquely identifying a copy of a motion picture
disposed on a media. The method includes the steps of selecting two or
more motion picture scenes. Each of the motion picture scenes is an
identifiable portion of the motion picture distinct from every other
portion of the motion picture. Once the scenes have been identified, two
or more sequences can be defined within each of the motion picture scenes
such that each sequence includes two or more frames. For example, the
motion picture can have three scenes, each divided into twenty eight
sequences, with each of the sequences containing 12 frames. Once the
scenes and sequences have been selected, at least one of the sequences
from each scene is marked to define a uniquely identifiable marking
pattern on the media.
