Automatic Content Recognition (ACR)

(temporary):

Smart TVs of multiple brands have a feature called Automatic Content Recognition, which sends several screenshots per minute of whatever plays on the device to the manufacturer for analysis. This includes content from external inputs and thus could include private photos and videos of the user, as well as third parties who never agreed to anything of that nature. This is required to be opt-in in the US, but most people inadvertently agree to it with the EULA of the device.
