Haven?t heard about Cinavia? Chance are, you will soon if you download pirated movies and attempt to play them back on a Blu-ray player or through a PS3. Cinavia is a somewhat new DRM technology that uses "audio watermarking" embedded into the audio stream portion of a movie. In a nutshell, what it does is compare the source of the audio to the format in which a movie was released (ie theatrical or commercial disc), and if the watermarked audio source detects a difference, the movie will either be mute (but most likely not play at all). So far, there have been at least two popular movies found on peer-to-peer that contain Cinavia DRM: TS/CAM versions of The Wolfman and Shutter Island.
How Cinavia is applied - an example: If someone were to "CAM" a movie and use a ?line? audio source (from a headphone jack, as opposed to recording the ?crowd?), the watermark in the ?line? audio will search for its match - in this case, being a theatrical source. Since a TS or CAM?s ?line? audio doesn?t match the original release format, Cinavia will block or restrict playback of the file. (Technical info can be found here and here).
