I posted another question where I mentioned something about this. I lost all of my digital channels a couple of days before this test - no signal at all so when the test came on I was interested to see what it'd say about my TV.
My local CBS station did the test during the news and when it switched to digital for 2 minutes and it let you know if your TV was ready for the change and I got the message that my TV wasn't. I switched to
DTV and Air while the test was going on to be sure.
It's odd because I've got a Samsung
DTV and strong indoor antenna and I was getting all of the stations perfectly before this week.
I live in the city between a lot of buildings but my signal was really strong.
