The watermarking and steganography facility provided by Cinavia is designed to stay within the audio signal and to survive all common forms of audio transfer, including lossy data compression using discrete cosine transform, MP3, DTS, or Ogg Vorbis. In conjunction with the existing Advanced Access Content System (AACS) digital rights management (DRM) inclusion of Cinavia watermarking detection support became mandatory for all consumer Blu-ray Disc players from 2012. Survives psychoacoustic compression models (MP3/Vorbis) and non-destructive audio transformations and filteringĬinavia, originally called Verance Copy Management System for Audiovisual Content ( VCMS/AV), is an analog watermarking and steganography system under development by Verance since 1999, and released in 2010.
