Have you ever been in such a dilemma that when you play a backup disc of a Blu-ray movie on your PS3 or other Blu-ray players for entertainment then something unexpected and unpleasant happens -- the audio of the Blu-ray movie gets muted or it just stops playing, and you see a message on the screen tells you that the content being played is protected by Cinavia and is not authorized for playback on this device. What happened?
What is Cinavia? How does it work?
Cinavia technology is a kind of new protection for movies from theaters and disc releases in DVD & Blu-ray, aiming to limit the use of copies of movies, television shows, and other professionally produced videos that have been made without the permission of the copyright owner.
It requires two parts to work: a proprietary imperceptible audio watermark, and a piece of hardware which is able to detect that watermark. When media with the watermark embedded in the audio track is played back on a system with Cinavia detection, its firmware will detect the watermark and check that the device on which it is being played is authorized for that watermark. If the device is not authorized, a message is displayed stating that the media is not authorized for playback on the device and that users should visit the Cinavia web page for more information. Depending on the device and firmware, once the message is triggered, the audio may be muted, or playback may stop entirely.
