Watching football this fall, I've been thinking about a little box that sits on my table and mutes the TV whenever an ad comes on. Not decoding HDMI HDCP or anything, but a webcam + AI or whatever that watches football with me and mutes ads. Similar to plane detection, maybe. Are there any projects like this?

Usually football trasmissions have identifiable elements in the screen, such as the score, the match title, etc... and those are fixed elements that do not appear in ads. For example: https://i.imgur.com/blebca8.png

Or the title bar below. You could do some basic OCR on a Pi, when the team names are readable, keep the volume up, when they are not, disable it.

related: automated Las Vegas plane spotting https://www.youtube.com/watch?v=d5PtT7KdlKc this person has some sort of OpenCV setup from a high-rise view. (bonus: Air Force One is currently there)

I'm kind of surprised that they would park it next to other planes like that. Especially with what appears to be no ground troops surrounding the plane.

That place is crawling with cops from the gutter to the street lights.

Nice idea! Related: In Black Mirror, they pause the advertisement when you disable the sound. So maybe you'll eventually have to use a separate sound system whereby they cannot detect that you're muting it. Then, they'll track your eyes and require you to watch the screen :) At which point do you stop consuming?

Black mirror haha I think Samsung actually does it.

Yeah... of course our execs took that Black Mirror course. Don't want to get left behind.

You can see from the photos how people might mistake planes for drones or UAP's.

Every single one of those pictures, even the blurry ones, even the ones taken at night, all look like airplanes. People aren't getting airplanes confused with drones because they look the same. People are getting worked up about drones because of collective paranoia, and then they are seeing what they want to see.

Your last sentence negated the first and only furthered my point. Moving lights in low visibility are open to a variety of interpretations.

Looking at the electric consumption of my 30 closest neighbors using an RTL-SDR, I'm still wondering what I should do with the information.

Are the electric readings sent in plaintext or trivially decrypted?

> Then, they'll track your eyes and require you to watch the screen :) Check out the recent controversy over Activision and Call of Duty. Evidently the game code requires access to your webcam and the company has patents on using your gameplay to train a bot that play like you do, then uses the idle time to make the bot play while you are away. This bulks up the pool of players ensuring you are matched with people re…

Source?

>then uses the idle time to make the bot play while you are away

Surely they're better off using a GPU cluster to do training like every other AI company?

only ethical move would be to move your own consumption to when theirs is lowest and not retain any data but your own

Given that drone warfare is now a thing this seems like it could be useful as the basis of a personal drone detection and warning kit that soldiers could wear over their helmet to spot drones and give say an audible warning in the soldiers ears that lets the soldier locate the drone direction and maybe azimuth with pitch - lower frequency for a low drone and high for one more overhead. Not sure if such a thing alread…

Shotguns have proven ineffective as drone defenses. Range is too short and the targets are too fast.

Was thinking of some recent videos where a small drone closes right up to an individual soldier and explodes - assuming those aren't AI generated. But I expect there will be drone hunting drones and drone dogfights will be a thing.

Unencrypted, I'm sure.

I hadn't thought to look for smart meters, but my RTL-SDR (and my Flipper Zero) can pick up all sorts of temperature sensors, etc.

A quick google found this rtlamr project with a number of blog posts about people doing this with it.

Rk3588's have HDMI input (I think with hdcp decoding) that you can use v4l2 API. The multiplane API can be a bit tricky, but otherwise somewhat trivial
