Difference between Digital-TV and HD-TV?
11 May 09
HDTV is Digital TV. but not all DTV is HDTV. Digital TV can be 480p (considered "enhanced definition TV"), or 720p or 1080i (both HDTV). If you already have and HDTV set and you are already using it to watch over the air DTV channels you will not see a change. You will however see the analog channels disappear. Cable and satellite users won't see much of a change, if any. These rules don't apply to cabble, expect that cable has to supply the local broadcast stations channels.
