I know there is a difference from the sdtv and the hdtv. What I want to know is this. When anyone would go to the store to buy a tv, say a few years ago, it either said hd, or nothing. Why did they start putting sdtv on the ad? Is that just a fancy way of saying it's a basic tv, or is it better then a tv that doesn't say sdtv? Sorry if this is so confusing. If I didn't explain good enough just ask, I will clarify. Thanks in advance.

There are only 2 types of TV's that are now made. Either a tv is high def with 720p or 1080p resolution.
Or, a TV is standard def (sdtv) with 480i resolution.
The only difference between the "old tv's we used to buy" and the sdtv's that are sold today is that today's tv's have a DIGITAL ATSC over-the-air (OTA) tuner. This means that you can hook an antenna up to a new sdtv and receive OTA digital signals. This includes high def channels. These sdtv's will just convert the high def channel (720p or 1080i) to standard def 480i.
All TV's made after April 2007 are required to have a ATSC digital tuner in them so they are ready for the anaolg cut-off date of Feb 17 2009.

The Numbers refer the the resolution of the picture. Larger Number, better Quality/ the number of pixels on the screen. The i and the P represent how the signal is sent to the Tv. In the long run it really wont make a difference, they both will look exactly the same. Go for the 1080 if you are going above a 32" tv, but stay at 720 if your 32" or below, the quality will look too clear. Meaning when you watch a movie with a lot of special effects, it looks choppy and fake.

SDTV means Standard Definition TV. Essentially, the same old regular TV standard we've been using for 40+ years.
I think they just decided to hang a name on it to differentiate it, because everything started being called "digital" as well, and was confusing people.

An SDTV set is designed to recieve HD signals but DISPLAY THEM in 480 format.
In other words, it's an inexpensive alternative to an HDTV set.
You don't have to worry about it becoming obsolete when they shut of the OLD analog transmitters in 2009...

so you know its not an edtv or an hdtv.
also probably because there are a lot so dopy people who need to be told "this is not an HDTV".
