The Difference between EDTV and HDTV
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. If the person selling you doesn't know the 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 distill the 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 in the 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, the quality deficiencies have become increasingly apparent.The ultimate answer to improving the quality of the image displayed on your TV is HDTV, however, as a step on the road to HDTV, the industry came up with Enhanced Definition TV, or EDTV. This system contains the same 480 lines as SDTV, but they are progressive scan.
Hence EDTV is also known as 480p. Progressive scanning just means that instead of splitting the signal into two fields and showing half the lines at a time, all 480 lines of video are shown at once. This results in a noticeable improvement in the quality of video.The bad news in relation to EDTV vs HDTV is that you need a completely new TV or projector to display both EDTV and HDTV. Most DVD players on the market today are progressive scan, meaning they output EDTV signals, however, in order to view the progressive scan picture in all its glory, you need a TV or projector capable of displaying it and that, unfortunately, means getting a new TV.In terms of content, there is very limited TV content available in HDTV format, and there is still wrangling about the standard for HD DVDs. However, every DVD disc on the market can be displayed in EDTV right now.Bottom line? Pretty much every HDTV projector or TV on the market today will display EDTV as well.
So while there may not seem like a great deal of point in getting a new display for the limited HDTV content that is available today, it is worth it to watch your DVD collection in EDTV, the difference between SDTV and EDTV really is that big..

HDTV, or high-definition television, uses high-resolution signals for the broadcast of television signals. As HDTV does not use traditional formats like NTSC, PAL etc. but mostly captures signals digitally, its introduction sometimes coincides with the introduction of digital television as well. HDTV has the DTV resolution with new set standards.
This combination creates striking image with stunning sound.
The main selling point of these sets is the high resolution they offer.
HDTV systems usually support some standard resolution and frame or field rates. With reference to HDTV, the format of the broadcasts is referred to using a notation describing the number of lines in the display resolution, progressive frames or interlaced fields, and number of frames or fields per second. For instance, a HDTV with format 720p60 can be expanded as 1280 ? 720 pixels, progressive encoding with 60 frames per second.

The Top 4 Things To Look For In A Plasma TV
If you have ever seen a plasma TV screen displaying HDTV programming, you know why so many people are rapidly discarding their old CRT type televisions and getting ready for the digital TV revolution. Plasma TVs produce such sharp, crisp images that they make perfect companions to the new HDTV standards that will be widely used in the coming months and years ahead. So if you happen to be in the market for a plasma TV here are the top 4 things to consider as you shop:
1. Determine if it is indeed a plasma TV, or just a plasma monitor. A plasma TV already has the tuner built in to receive it's own television signals and it usually has it's own built in speakers.
Plasma monitors on the other hand, are just simply large display screens without the tuner and speakers. If you subscribe to cable or satellite TV, you can use their tuner for programming, but you will still need speakers. Just understand what you are buying beforehand.
2. Is the set HDTV enabled?...

Audio Choices for HDTV
HDTV essentially provides a far superior sound quality just because the audio of HDTV is transmitted through digital signals. The distinction in sound between an HDTV television and a regular analog television is rather perceptible. The difference is more like the one you get between an audio CD and an audio cassette.
The difference in audio quality offered by HDTV televisions is however more than that. Most HDTV programs are transmitted in Dolby Digital 5.1 surround sound. So to maximize the advantage of this technology, you need to have the proper equipment.
What is Dolby?
