The standards for current broadcast are on 540 scanning lines, which means that the picture is broken into 540 rows, and all 540 are refreshed according to the Hertz rating of the television (usually 50-100) which gives a moving picture.
In HDTV there are either 1080 or 740 lines, which are refreshed at the Hertz rate. The practical upshot of this is that the pixellation of the picture is condensed. The effect is rather like the fineness of the grain on a photographic negative- the finer the grain the clearer the picture.
Beware of HD emulation which is not true HD and doesn't always work the way it should. Lots of televisions only work in the lower register of HD too, particularly the cheaper ones.
Very few broadcasters are actually using HD broadcasting and you will need extra equipment to receive it. This will not be cheap. Because of the different technology it is not possible to convert existing sets to high definition, and the cost is a major setback to the take-up of HDTV. Another consideration is whether you can receive it terrestrially. If you have Sky there isn't a problem receiving it, but again you will need Sky HD equipment and a new LMB will have to be fitted to your dish, or a new integrated dish installed. Sky can be reticent about the prices for this but they do some packages and it's best to call them and find out how much they're willing to do it for. Again you will need a TV set that can work in HD and none of the cathode rays as far as I know are capable so your choice is LCD and Plasma- EXPENSIVE.
So HD Ready means it can display HD Broadcasting providing the right equipment is hooked into it and a broadcast signal is available. Hope that's all clear.

HD ready refers to TV sets that can display high definition pictures, but do not include a tuner for digital broadcasts. These sets can be used with cable or satellite systems as well as the new high definition DVD players. A tuner is only needed to receive off-the-air HD broadcasts. However, FCC has required nearly all new TVs to include digital tuners, so any HD television you buy that was manufactured last year or this will include a tuner. The term "HD Ready" will soon be a thing of the past.

Paul, it stands for high definition but I'm sure you could think of other words! When you have HD from Sky you have got to pay a couple of hundred for the box. Some of the programmes are already HD (football spectators faces look really blurry. With HD its brilliant) Have a demo at an electrical store.

High Definition.
Digital images are made up of dots called pixels. High Definition has 4 times more dots per inch than normal televisions.
The main reason for High Definition is becuase TV screens are getting larger and larger (projectiong and plasma TVs), and with bigger screens comes lower quality becuase the dots appear bigger. Having x4 more detail resolves this issue.
Also conematography is coming on leaps and bounds in terms of quality and special effects, which are enhanced by high definition clarity.
You won't notice the difference wating a normal tv show on a small 14" screen however.
Only certain TV channels and certain films (recorded in HD) will be available in High Definition. Having a HD TV won't make old films HD.

High definition, or 1080 interwoven lines of information. It basically means that there can be finer detail and crisper lines, overall a better picture. It must be noted that this isn't the best there is though! There is such thing as ultra-definition, or UD, however this is many many years from being produced, so mere HD will have to suffice for now

HD TV ready means that the picture will produce high definition, but lacks a tuner to receive any station broadcasting in high definition.

You will have to check the specs on the TV,
but it will at least be able to reproduce a 768p
resolution. Since it is only HD "Ready", you
will need a High-Def receiver or antenna or
other source (i.e. HD DVD, Blu-Ray Disc, or
DVR) in order to view at this resolution level.
