I actually do not have the comprehension in deciphering digital and analog stuff. It was only recently that I was able to figure out why an HD TV is more apt for the latest communication and entertainment gadgets in the market today. We have around 7 installed televisions all over the house and not all are HD. There are 3 more fairly new TV sets not installed too. Now, it would not be frugal and wise to just junk the fairly new analog TVs, right? The wise course is to get a digital receiver which is a converter of some sort. Yes. I am not very technical so the "some sort" description would have to suffice.
