That's extremely hard. Good luck getting something like that to actually work. The senior electronics engineer who might be able to create such grabbing system has probably a better-paying job somewhere else.
If you could manufacture a device that would bypass virtually all forms of video/audio DRM, you could make some nice pocket change I'm sure. Or at the very least you could impress at a convention.
I am more bored than you could ever possibly be. Go back to work.
