The Difference between EDTV and HDTV

Written by Kenny Hemphill

Confused by EDTV vs HDTV? We don't blame you. The number of acronyms floating about with regard to digital TV is frightening. What's even more worrying is that very often they are used by people who have little or no knowledge about what they mean. Ifrepparttar person selling you doesn't knowrepparttar 109994 difference between EDTV vs HDTV, how are customers supposed to decide which TV or projector to go for?

In our guide below, we've tried to distillrepparttar 109995 technical info into as few words as possible and make it as straightforward to understand as we can.

To properly explain EDTV vs HDTV, we need to step back a bit. Traditional TV has 525 lines of video which are interlaced. Interlacing just means that every frame of video is split into two fields and each field is shown alternately. Although there are 525 lines inrepparttar 109996 signal, only 480 lines contain video, so it is sometimes referred to as 480i (480 lines interlaced). This is known as Standard Definition TV, or SDTV. While this has worked well enough for fifty years, as TV sets have got bigger and projectors more popular,repparttar 109997 quality deficiencies have become increasingly apparent.

The ultimate answer to improvingrepparttar 109998 quality ofrepparttar 109999 image displayed on your TV is HDTV, however, as a step onrepparttar 110000 road to HDTV,repparttar 110001 industry came up with Enhanced Definition TV, or EDTV. This system containsrepparttar 110002 same 480 lines as SDTV, but they are progressive scan. Hence EDTV is also known as 480p. Progressive scanning just means that instead of splittingrepparttar 110003 signal into two fields and showing halfrepparttar 110004 lines at a time, all 480 lines of video are shown at once. This results in a noticeable improvement inrepparttar 110005 quality of video.
