MySpace.com is testing technology from Audible Magic that blocks distribution of user generated videos containing unauthorized copyrighted content.

Audible Magic's digital finger printing solution screens video uploaded by users and blocks any video matching a fingerprint in MySpace's database.

The move -- which is being billed as a "pliot program" -- comes three months after Universal Music Group filed a copyright infringement lawsuit against the social networking giant and its parent company News Corp. for enabling unauthorized distribution of music videos.

In announcing the launch of the new video filtering solution MySpace claimed it is "already blocking users from uploading any audio or video files containing Universal Music Group's music that is not authorized, while allowing all of the extensive free authorized promotional uses that UMG and its artists currently enjoy on MySpace." The social networking giant also stressed that it has offered the full-range of its content protection tools to all other major music labels and to other content owners, free of charge.

"MySpace is dedicated to ensuring that content owners, whether large or small, can both promote and protect their content in our community," said Chris DeWolfe, CEO and co-founder of MySpace.

Last November MySpace launched a similar content filtering solution for audio files using technology from Gracenote. That solution blocks unauthorized uploading of music.

MySpace says it has also developed a special content take-down tool to make it easier and more efficient for copyright owners to request removal of any user-posted content they claim is unauthorized.

Media companies are putting increasing pressure on operators of viral video communities and their parent companies to curb unauthorized uploading of film and TV files.

UMG is reportedly close to settling with Bolt.com--another social networking
site offering viral videos that it filed suit against for copyright infringement around the same time of the MySpace action. In tandem with the settlement deal, which could be announced as early as this week, Bolt will sell itself to rival gofish.com for $30 million.

Meanwhile Viacom last week ordered the removal of more than 100,000 infringing clips circulating on YouTube, a unit of internet search giant Google.

YouTube late last year announced content licensing deals with Warner Music Group, UMG, and Sony BMG Music Entertainment ad vowed to implement a new
content filtering technology that would block unauthorized distribution of copyrighted works. However that technology is yet to launch.

The company is yet to win similar support from film and TV companies.

At the same time Google is feeling increasing heat from the film industry, which is complaining that the company is benefiting from doing business with Web sites that offer illegal movie downloads.
