#2> Smart TVs from Samsung and LG take screenshots of what you are watching even when you are using them to display images from a connected laptop or video game console

Unfortunately I wasn't able to find a non-paywalled link myself. This _appears_ to reproduce the article text: https://kbin.melroy.org/m/technology@lemmy.world/t/480211

#3> [...] in their automatic content recognition systems [...] Samsung TVs can take screenshots every 500 milliseconds and LG TVs every 10 milliseconds
I wonder how much energy it take to analyze 4k images 10 times a second?

I have to think that whatever they're using this for, it could be done at a much lower data resolution.

#5Best Buy sells the "DuraPro - Partial Sun Series 43" Class LED Outdoor Partial Sun 4K UHD TV (2023)" which is supposedly a "non-smart" TV. I just ran a search and don't know anything about it, personally. They could still be screenshotting AFAIK.

10ms is 100Hz not 10Hz.
A conservative assumption would be that they use all spare cpu time for spyware? Maybe 1-10W extra if small arm processors?

#9Alphonso inc. develops the tech https://lgads.tv/site-privacy-policy/. Looked into the LinkedIn of some of the employees and it looks like a huge operation.

#10Someone needs to put a network sniffer on a bunch of different TVs and see exactly what traffic they're generating and how much. Sending 120 4k images per minute (or worse, 6000 for the LG) on a residential WiFi connection should be pretty obvious, and it should be fairly easy to block too.
