NBC Universal today revealed in a discussion with the New York Times that Microsoft is working to implement an anti-piracy filter into its Zune media players. While not outlining the amount of progress, the studio's digital chief J. B. Perrette says that Microsoft has agreed to work on a "cop" that would check the legitimacy of videos loaded on the device; those deemed illegal would refuse to play. The implementation would function similarly to automatic blocks being tried at YouTube and other sites, which are claimed to stop easy bootlegging by checking such data as the title or basic track information.
