Home gateway manufacturer Thomson plans to incorporate video watermarking technology into future set-top boxes and other video devices. The watermarks, unique to each device, will make it possible for investigators to identify the source of pirated videos. Thomson developed the technology, NexGuard, to identify individual copies of the films distributed digitally to cinemas or on DVD as preview copies for reviewers and awards juries. NexGuard can mark video encoded in MPEG-2, MPEG-4 AVC (H.264) and VC-1 formats.”]
