Here’s something that the major movie studios might want to see for themselves. The S-VIEW SV510 is a portable video key that can be programmed ahead of time. Unless you plug this key into a USB port and enter the access code, you can’t watch the movie.

The access code is from 6 to 12 digits and can be set by the movie studio or download service to match the predetermined code assigned to the movie in its original incarnation. It also has a handy remote-disconnect feature, in case it gets lost or stolen.

The device comes from a company called Cinea, a subsidiary of Dolby Labs that offers a handful of other products, all in the anti-piracy field.
