I think there may be a bit of confusion, and hopefully I can help you in terms of comparing the notice and notice and notice and takedown. In terms of film and television content, there are two different types of online piracy the business folks here are concerned with. The first is content that is hosted and allows people to either download and stream, and that's where you have a notice and takedown regime to deal with, because you want to get that infringing content off the web.
In Europe, for example, they deal with it in a different way. They say you can't have the benefit of a safe harbour if you have actual or constructive knowledge of what's happening on your server.
