> So they are claiming that ACR is done entirely through audio processing, and no visual data from the screen itself is used? That...doesn't seem plausible.

It's probably easier to do and every bit as accurate as just using a screenshot.

And it's still exactly what I don't want them doing. There's literally zero reason for LG to be building an advertising profile on me because I was foolish enough to buy one of their TVs. This isn't something that makes their products better, it's spying.

Here's how it's been done in the past

Audio is a bit easier to turn into a fingerprint for identification vs video. Video has a lot of smaller subtle changes that happen from things like compression which make it a lot harder to identify. It's why youtube still hasn't figured out piracy, but they'll knock you immediately if you play 5 seconds of copyrighted music.

To me, it's not even about why they're doing it (building an advertising profile). I don't want them doing it at all, for any reason.

When I buy something from the store, my relationship is between me and the store, for the 30 seconds it takes for me to pay for it. I don't want an ongoing relationship with the device manufacturer. I don't want to be tethered in any way to the manufacturer. I don't want to have an account with the manufacturer. I don't want the device sending anything to the manufacturer, advertising related, telemetry, or even a single bit "user has used your product." Do you get it, manufacturers?? I don't want any kind of relationship with you! I want to purchase my product and use it by myself not with you.

I feel like the world is bossed by people who read (well, ok listened to a 5 minute summary on a grindlife podcast at 1.5x speed) about the Trojan Horse and thought they smelled a business opporunity.

It’s a lot less data to process as well.

Is it within fair use to surreptitiously record copyrighted music?

Unless the piracy is silent, surely audio fingerprinting would catch it?

As much as I detest ACR this seems more plausible than screenshots but I wouldn't trust LG regardless.

Audio is much easier to fingerprint and match against content.

wouldn't taking screenshots in fact not always be possible depending on the content you are watching? For example netflix with their hardware level drm? (Although its their TV they possibly have ways around that with some custom hardware)
