They do this from their television broadcast station, I believe. They don’t come into the house and do it without your permission. They then run a script telling you whether you are prepared are not. How is this done?
My local news station performs test on tvs to determine if ready for switch to dtv on 6/12. How is this done?

your tv will bounce them back with a negative or not reciving signal if you dont have a box.
its like calling a phone number, if ut says its disconnected, then it doesnt work
yes maybe good depends
They are sending an analog signal that says something like. “If you are seeing this you failed the test” and a digital signal that says. “you passed’. This just displays on your tv for your own benefit. The station has no way of knowing if your tv passed or failed. Your tv only receives information, it doesn’t send it.
Agrees with Tyler: “They are sending an analog signal that says something like. “If you are seeing this you failed the test” and a digital signal that says. “you passed’. This just displays on your tv for your own benefit. The station has no way of knowing if your tv passed or failed. Your tv only receives information, it doesn’t send it.”
Also, the station has the option to send different signals to the analog transmitter than what they send to the digital one. Therefore this test message is not sent out over the digital transmitter.
