Cinavia watermark on all movie theater soundtracks released via film distribution networks; the second use-case is for the provision of a Cinavia watermark on all Blu-ray Disc releases that points to the presence of an accompanying AACS key. If a "theatrical release" watermark is detected in a consumer Blu-ray Disc audio track, the accompanying video is deemed to have been sourced from a "cam" recording. If the "AACS watermark" is present in the audio tracks, but no accompanying and matching AACS key is found on the disc, then it is deemed to have been a "rip" made by copying to a second blank Blu-ray Disc. , known hardware players which can detect Cinavia watermarks include the PlayStation 3 (began with v3.10 System Software), as well as newer Blu-ray Disc players. Overview Cinavia works to prevent copying via the detection of a watermark recorded into the analog audio of media such as theatrical films and Blu-ray Discs. The intent is to prevent all copying, both counterfeit copies and legal copies of one's own content (for example, format shifting). Verance claims on their website that, while the watermark is able to survive recording through microphones (such as recording a film in a movie theater with a camcorder), as well as compression and encoding, it is imperceptible to human hearing, and the presence of the watermark does not affect audio quality. When media with the watermark 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 (such as not being an authorized movie projector in the case of a cam bootleg, or not utilizing AACS in the case of a copy of a commercial Blu-ray Disc or CSS in the case of a copy of a commercial DVD), a message is displayed (either immediately or after a set duration) 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. Messages Following an intervention by the Cinavia+AACS system, one of four messages is displayed to reflect the specific situation in which a watermark was detected. The messages are numbered "Cinavia message code
