Digital Signature

Just when you think you got this licked.

The productions want to put a digital signature into our DVD presentation.

"I've seen that video before. Here's the serial number...."

Of course, we not allowed to change any of the visible pixels that they spent months creating.

Any ideas?

Sounds like you want USVO's MediaSentinel product. It puts forensic watermarks onto SD video in real time during a Digibeta-to-Digibeta dub.

NexGuard is great
