An EDTV is a display that projects an image at 480p. This is normally a display with a pixel value of a least 600 x 480 pixels. A standard TV can not produce a 480p output so you need at least a progressive scan DVD player and an EDTV or equivalent resolution to see the results of this improved technology. Most of the DVDs that we rent today will play the 480 progressive scan format on an EDTV or equivalent resolution if you have a progressive scan DVD player; the quality is so good many people think they are watching HD when in reality they are not.
