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.
