The Teletrax® Story

For decades, owners of all kinds of video footage—from news to soap operas, sports matches to feature films—have struggled to get accurate information on when and where their footage was broadcast. It was a problem crying out for a digital solution…

Teletrax® is the most accurate way to monitor how your broadcast material is used. It combines advanced technology with a worldwide monitoring network. To understand why Teletrax is better, look at how it emerged…

The revolution started in the Netherlands where the Philips' watermarking technology (named Watercast) was pioneered. Scientists and engineers at Philips (now Civolution) had been experimenting with a range of technologies for making broadcast footage digitally traceable. Solutions such as audio watermarking were rejected since they could be removed at the dubbing stage. Fingerprinting technologies—where the unique properties of an image are analysed—were rejected as problematic, possibly inaccurate and slow. The most accurate and reliable approach proved to be video watermarking where an imperceptible code is placed in the picture. This can be detected instantly and permanently since the only way to destroy the code is to destroy the footage itself. Watercast was the technological bedrock on which an accurate broadcast monitoring system could be built.
