[WM]: [WM] Protecting from screen capture

["Babu, Mandava" <Babu@crimsonlogic.com>]

Hi All,
 
Can some one give me pointers to find the relevant documents or technology which talks about protecting the illegal copying of
cinema. Is it possible to watermark traditional cinema screening ? 
 
The real problem is: When the movie is being screened in cinema, few ppl just walkin with a digital v. camera and shot the whole
movie. The immediate next day you can see the pirated VCD's are available in the market. Is some one know of any watermarking
technology that can protect the film ?
 
regards
