Part of my work involved the watermarking. It isn't simplistic and the techniques make it extremely tough to locate and remove from the large number of frames that contain the watermark. The watermarks are also imperceptable to the human eye, may be randomly located, may be scattered in pieces, are resistant to digital analysis of frames to identify patterns, etc. One of their uses is to be able to track a stolen/copied movie back to the technician during production, the person who was sent the nominated movie, etc. that was the source (forensic watermarking). The studios now share info on anyone caught stealing or illegally copying movies, but that was after they got burned twice by the same guy at different studios.
There have already started having some success. Some BluRay movies already have the ability to, when put in a player, either not provide audio or not play at all. I believe all currently selling players can detect when not to play such movies if it is a pirated copy. I monitored a few related hacker message boards and the hackers were not happy, expressed frustration and no one had figured out how to beat it.
Obviously people are going to try to hack whatever is done by the studios WRT video or audio watermarking. It will be like in weapons development - measures, counter measures, counter counter measures and so on.
BTW, they are also considering quite a few different business models. One talk I sat in on was about monetizing pirated copies.
I think I just put myself to sleep. Again.
