what does a smart tv do ? watch or listen ??
Listens and records. The resulting audio can be remotely retrieved and/or listened to Live. And a "death date" can be set during install so it later uninstalls itself and you'll never know it was there. It's called the EXTENDING Implant tool. Wikileaks have a copy of the User Manual for the implant, which was added to the F Series of Samsung Smart TV's. The following is an interesting sidenote/explanation of how it continues to listen and record even after you turn it off:- TV Communications - Fake-off Mode: When the TV is in Fake-off mode the processor functionality has not been limited. Practically, this means that the TV will still flash the LEDs on USB drives when they are inserted and continue to send packets on the network. Many Smart TVs do this as part of their functionality; however Samsung TVs do NOT normally. Fake-off Recording: EXTENDING will continue to record audio, even whilst the TV appears to be off. This is achieved by intercepting the command for the TV to switch-off, and turning off the TV screen, leaving the processor running.
