Okay kiddo, so do you remember what a regular TV looks like? It has a big square screen and shows pictures in different colors, right?
Well, enhanced-definition television (EDTV) is like a fancier version of regular TV. It still has a big square screen, but the pictures it shows are even more clear and detailed.
You know how sometimes when you watch TV, the picture looks kind of blurry or pixelated? That's because regular TV has a lower resolution, which means there are fewer little dots (called pixels) making up the picture.
EDTV has a higher resolution, which means there are more pixels making up the picture. This makes the picture look sharper and clearer, so you can see more details in the show or movie you're watching.
So, in summary, enhanced-definition television is like a super clear and fancy version of regular TV that shows more details in the picture. Cool, huh?
