> Roughly twice per second, a Roku TV captures video “snapshots” in 4K resolution. These snapshots are scanned through a database of content and ads, which allows the exposure to be matched to what is airing. For example, if a streamer is watching an NFL football game and sees an ad for a hard seltzer, Roku’s ACR will know that the ad has appeared on the TV being watched at that time. In this way, the content on screen is automatically recognized, as the technology’s name indicates. The data then is paired with user profile data to link the account watching with the content they’re watching. https://advertising.roku.com/learn/resources/acr-the-future-...

I'm on my second one and I've owned them since the first version. My current one is the first generation 4k that's ... seven years old? Still works like new.
It was a rabbit hole and in the end I got back using my NVIDIA Shield. This is about 10 years now, but it’s actually still the best option.
