HDTV

What is EDTV? EDTV stands for Enhanced Definition TV. It is a kind of television technology that is somewhere between the quality level of ordinary PAL or NTSC television and HDTV (or High Definition TV). EDTV vs. HDTV: While EDTV has a somewhat higher resolution than ordinary television signals that are broadcast in the United States and Europe (the high resolution is a result of its greater number of vertical scan lines, which prevents visual artifacts from forming in the image as a result of low definition in the vertical direction), it is still less than HDTV. However, because it has additional scan lines and additional information it can be more easily converted into HDTV without losing as much of its quality. The quality level of EDTV is similar to the output of a DVD player that uses progressive scan (progressive scan adds more scan lines to the vertical section of a television signal).

EDTV vs HDTV, in greater detail: Some EDTV oriented televisions, displays and consumer products have come out over the past couple years, but they are now being taken out of circulation in favor of the HDTV high definition flat screen televisions. It is still possible to buy a plasma EDTV (Sony 42" plasma EDTV, LG plasma EDTV, 42" Samsung plasma EDTV, the most popular size for EDTVs seems to be forty two inches) or an LCD EDTV (Samsung EDTV, LCD 15" EDTV, EDTV monitor Sanyo LCD TV). In an EDTV HDTV compare review, HDTV will certainly come out on top for its greater definition, resolution and compatibility, however EDTV has seen uses such as being the output format of the Wii, and being the format in which the Fox Network began broadcasting digital TV before switching to HDTV in 2004.

Facts about EDTV: EDTV has fifty percent more vertical resolution than ordinary broadcast TV in the United States because of its additional scan lines. EDTV can be broadcast by a digital TV station so that the station can improve its broadcast quality while broadcasting multiple programs at once. EDTV is usually implemented at the resolutions of 480p or 576p. The Wii outputs an EDTV signal at the 480p resolution of EDTV which appears on a non EDTV television set as a normal signal without the additional interlaced data. I hope that this has been an informative article on the characteristics of the recent technology EDTV (Enhanced Definition TV).
