Tom Perkins, a legendary venture capitalist and partner of Kleiner Perkins Caufield & Byers, alluded to the research at a dinner gathering here Tuesday, part of the Progress & Freedom Foundation's annual conference.
"We have a new projection technology that we think will make the image immune from a teenager sitting in the (audience) with a video camera," Perkins said.
An HP spokesman confirmed that the company was working on a research project fitting that description, but declined to provide any further details.
If adopted, the company's technology could help prevent the piracy of movies with handheld camcorders, a technique that typically yields low-quality results but nevertheless has bedeviled the movie industry. A federal law enacted this springwithout permission of the copyright owner.
Another company, called Cinea,in 2002 for a similar idea. That company used slight modifications in the "timing and modulation of the light used to display the image" in order to distort any videotaped version of the film, the company's grant proposal said.
Cinea wasin late 2003.
Perkins didn't elaborate on what HP had planned, and joked that he probably wasn't supposed to divulge what he did. "I'll probably get whacked for saying this," he told the audience at the conference.
HP sells a line of digital projectors for office and home theater use.
