The researchers have discovered that automatic content recognition (ACR) tracking is active most of the time, even when TVs are used as “dumb” HDMI devices. In other words, the TV manufacturers are monitoring your private moments as well. There’s apparently no monitoring of streaming content in the UK, but there is in the US.
The only good news is that these TVs can seemingly be configured to disable ACR, provided the owners know this activity is taking place and are able to find the right settings. (I recently looked at the configuration of our TVs again, and understanding the various settings was far from easy.)
It’s a bit difficult, you’ll need be good with your solder.
I dunno. I was able to open my wife’s Sony Xperia to DIY battery swap, and then break (and fail to resolder) the antenna in the process. Can’t be that hard on a smart TV.
