Digital TV just allows you to deliver your standard 625 lines of picture information in a different way, that is less prone to interference.
High-Definition TV improves the resolution of the picture you watch, so instead of being made up of 625 lines of picture information, it is made of rather more - somewhere over 1,000, IIRC.
The lines of information that make up your picture are drawn horizontally, so it doesn't matter whether you have an old 4:3 or a new 16:9 (widescreen) aspect ratio TV, the picture is only 625 lines.
