CONTENT PROTECTION FOR AUDIO AND VIDEO CONTENT
Music, film and video piracy is a multi-billion dollar problem that undermines the growth of new models for offering entertainment to consumers and harms all participants in the global entertainment industry. Modern digital formats employed for sale or rental of commercial audio and video content to consumers-such as DVD, Blu-Ray Disc, and iTunes-incorporate content protection technologies that control access to and use of the content and limit its unauthorized copying and redistribution. Parties seeking to engage in unauthorized distribution and copying of protected commercial music or video content must circumvent the content protection to obtain a decrypted copy of the content. Once a decrypted copy of the content is obtained, the content protection technology is no longer effective at governing access to it and the decrypted content may be subject to unlimited use, copying, and redistribution.
CONTENT PROTECTION AND DIGITAL WATERMARKING
Digital watermarking provides an added layer of security to the content protection chain to deter unauthorized use of content by embedding watermarks that identify the permitted uses of the content into the music or motion picture soundtrack prior to theatrical, packaged media (Blu-ray Discs, DVDs) and online digital distribution. Devices read the watermark during playback or copying of content. If the watermark indicates that the use is unauthorized, the playback or copying is stopped or the audio is muted, and an explanatory message may be displayed.
