Short for Enhanced Definition Television, EDTV is a common name for a particular subset of the DTV (Digital Television) standards, but is considered to be specifically a part of the HDTV format. EDTV offers advancements over SDTV, but not near the quality and performance of HDTV. On a large display screen, EDTV only simulates HDTV viewing quality. EDTV operates as 480p (where 480 represents the vertical resolution and p represents progressive scan). To take advantage of the 480p standard, you must use a video source that outputs that signal (i.e. a DVD player) and the display must be able to read the 480p input signal. EDTV also offers the benefits of Dolby digital surround sound.
