Enhanced-definition television, or extended-definition television (EDTV) is an American Consumer Electronics Association (CEA) marketing shorthand term for certain digital television (DTV) formats and devices. Specifically, this term defines formats that deliver a picture superior to that of standard-definition television (SDTV) but not as detailed as high-definition television (HDTV).
The term refers to devices capable of displaying 480-line or 576-line signals in progressive scan, commonly referred to as 480p (NTSC) and 576p (PAL) respectively, as opposed to interlaced scanning, commonly referred to as 480i (NTSC) or 576i (PAL). High-motion is optional for EDTV.
In other countries definitions may vary.

Famous quotes containing the word television:
“All television ever did was shrink the demand for ordinary movies. The demand for extraordinary movies increased. If any one thing is wrong with the movie industry today, it is the unrelenting effort to astonish.”
—Clive James (b. 1939)
