|TTR's proprietary music anti-piracy technology is a unique hardware-based technology which prevents the unauthorized copying of CDs.
MusicGuard protection is on the CD itself and is introduced as part of the production process. During the glass mastering process, a specially modified CD-encoder introduces selective alternative alterations to the EFM data stream. These alterations do not affect the audio quality of the original CDs in any manner. CDs protected by MusicGuard play normally in the existing base of CD/DVD players around the world. Music quality is exactly the same, as it would be if the CD were not MusicGuard protected. When one tries to make a copy of a MusicGuard protected CD with any of the many CD-to-CD copying programs or "track rippers", the copy is unusable. Either the copying process itself will abort or the quality of the unauthorized copy will be unacceptably inferior to the original music. Similarly, attempts to produce MP3 files from a MusicGuard protected CD will either fail or result in inferior and unusable audio.
