EDTV
Enhanced definition television, extended definition television, or EDTV is an unofficial designation for certain SDTV formats.
EDTV generally refers to a standard-definition 704 pixel × 480 line signal that is broadcast at 60 progressive (complete) frames per second (NTSC) or 704 pixel × 576 line signal that is broadcast at 50 progressive frames per second (PAL). This is commonly referred to as "480p" or "576p". A standard definition television signal is broadcast with interlaced frames and is commonly referred to as "480i" or "576i".
EDTV signals are generally broadcast in a 16:9 aspect ratio, and are generally considered equivalent in picture quality to the DVD format.
Currently, Fox Network is broadcasting in EDTV in the US, although they are currently migrating to HDTV.
