Future set-top boxes and gateways from Thomson SA are going to come with video watermarking tech that will allow investigators to pinpoint the origin of pirated videos. The tech, NexGuard, identifies "individual copies of the films distributed digitally to cinemas or on DVD as preview copies for reviewers and awards juries." Before video content leaves a gateway or set-top box, it embeds a watermark unique to each device using the box's digital video chip.
The watermarks identify both the "network operator distributing the content" and the individual device. A spokesman said that people "should not be upset about this unless they are widely redistributing content." Thomson sees it as a way to "slow down piracy without limiting the use of the consumer."
So, if you feel upset or limited, that means you're a pirate.
