That type of technology alone would cost you at least $2M to build.
So either your statement is incorrect or Vizio got a terrible ROI on this (sans fine).
Just use something like pHash (e.g. https://github.com/JohannesBuchner/imagehash), screen cap the centre of the screen (say, a quarter of the screen in total) every minute, hash and then send the 8 byte hex string back to home base.
Even if you had the system up and running, you would still need to create a large database system managing 100 billion data points each day and integrate the stream of information with your customers APIs.
$2m worth of developer time going into this project is very likely. Thinking you could do this in a couple of days is simply ignorant.
