so, you don't think the white noise video encodes any information about the device being paired and is actually pre-recorded and is exactly the same for every pairing process. In other words, if you you try to pair two sets of devices in the same room at exactly the same time -- it would get confused?

It would probably get confused, or whatever watch can communicate with the phone first would be paired and the other would just time out.

Nothing in that video looks like the camera is facing the watch long enough to capture any important data. It might be watching for the <BACK and (I) icons on the screen just to hold off showing the sync video until the watch is in-hand.

it actually took me good 15-20 seconds or so to pair up (holding a camera pointing at the watch), that's why I made an assumption there is some encoding/decoding going on.
