Whats the difference between an HDTV and a digital-ready TV?
HDTVs are able to receive and display all 18 digital TV formats approved for broadcast in the United States. In addition, they have a widescreen aspect ratio and are able to display pictures at a higher resolution. Digital-ready TVs (sometimes called other names, such as HDTV-ready or HD-compatible) do not receive digital signals they have no built-in decoder. Instead, they are equipped with inputs that will allow you to add a separate decoder box later on to enjoy the equivalent of HDTV.
