Thomson watermarking technology adopted by server companies

Top d-cinema server manufacturers Doremi, GDC, QuVis and Tamedia are adopting Thomson’s NexGuard digital cinema watermarking solution to help protect motion picture content from in-theater piracy.

The server companies will incorporate NexGuard audio and visual forensic content identification technology into their exhibition hardware for digital cinema applications. Doremi recently completed testing the watermarking solution and is already shipping its NexGuard-enhanced product line, while QuVis, GDC and Tamedia are finalizing the integration process.

Thomson’s NexGuard watermarking solution embeds the date, time and place of projection into a digital motion picture’s image and soundtrack during playback in movie theaters. When the information is extracted from pirated materials with NexGuard’s detection and recovery system, it pinpoints the exact source of the leakage.

The company said that NexGuard’s watermark exceeded the Digital Cinema Initiative (DCI) specifications in its ability to withstand compression in hard media and on the Internet, and in its capacity to store more than the prescribed amount of critical identification information. It is invisible during both 2K and 4K exhibition and inaudible in multichannel playback.

In addition to NexGuard, Thomson’s proprietary forensic watermark fuels NexTracker, the company’s broadcast and Internet content management and verification system, and MediaSign, its digital imagery and printed document security solution.
