A method for protecting a DVD video includes deriving a distinct version of the video data from sequential distinct data objects contained in a content database. Each data object has at least one member and selected data objects have at least two members that produce discernibly different analog output signals. In the exemplary embodiment, the members of a data object correspond to alternate "camera angles" in the DVD context. By selecting among alternate data objects available in the content database, the identity of an agent who is to be responsible for that copy is encoded in the particular copy. A modified player encodes the identity of the player into the reproduced analog video signal by making choices from among the members of the selected multi-member data objects.
