High Definition TV

What Is HDTV And How Does It work?
Jim Johnson
In the field of television broadcasting there are plenty of acronyms to go around and it all can all be very confusing. One of the most common terms you will read about and hear is HDTV. A lot of people use that term in articles and at the consumer electronics stores and assume that everyuone knows exactly what they are talking about. But plenty of us are not tech-heads that know all the latest jargon in the electronics world, so let's go over just what HDTV is and what it means for you.

First of all HDTV stands simply for High Definition Television. It is a broadcasting standard for sending television signals in digital format instead of the old analog way. Back in days past, the television signal that originated at the tv station was sent in analog format that ciould only handle so much data for both picture and sound and once that limit was reached, it didn't matter how great the television set was that was receiving the signal, it would only look and sound so great.

However, with the advent of the digital age, electronics technology has improved to the extent that we can do much better than analog television signals now, and instead we can record the signal digitally, braodcast it not only by antenna but by cable and satellite and display it on greatly superior television screens. All of this results in picture and sound that is vastly improved over what we have been used to watching on television for many years now.

To give you an idea of how much improvement has been made in television equipment, just consider the screen or monitor itself. Standard television monitors have only been able to display about 525 lines of information on the screen, while HDTV enabled monitors can display up to 1080 lines on the same screen. That's almost double the detail of analog television. What that means for you is much improved resolution, color, and smoothness of action on the screen. And it will also be easier on the eyes as well.

Since all television broadcasts have been mandated by the FCC in the US to eventually be shown in HDTV format, that pretty much makes all analog TV systems obsolete. So if you are looking to buy a new television, it makes a lot of sense to buy a high definition television, as that will soon be the standard for all televisions sold for some to come.

Choose The Right HDTV Antenna For Your Set-Up

Choosing an HDTV antenna can be a frustrating business.

However, if you prefer to receive HDTV through an antenna, rather than a satellite or cable subscription, there are a couple of things that will make life easier.

First of all, if you can, you should opt for a roof or attic mounted HDTV antenna.

This will give you the best chance of picking up a good signal and is a must if you are in an area where signal strength is poor.

Such as where you live some distance away from the nearest transmitter or where your signal is affected by hills or other environmental factors.

If an external HDTV antenna is not an option, perhaps because you live in an apartment or in a building of historic interest, then you`ll have to go for an internal, set-top antenna.

Unfortunately, every HDTV antenna is not alike and the quality of your picture can vary greatly depending on which antenna you choose. So how do you know which one to go for?

Perhaps the best way is to find out from people who already has an internal HDTV antenna, how it works for them. The best way is to talk to people you know - particularly those in the same apartment block. Failing that, user reviews on the Web are a good source.

Amazon sells a number of antennae for HDTV and user opinion on them varies greatly. For example, the Terk HDTVi Indoor VHF/ UHF HDTV Antenna gets slated by users, while this Gemini ZHDTV1 HDTV-UHF Digital Indoor Antenna, which is actually cheaper than the Terk, gets great reviews.

As with any item of electronics, the key is to do your research.

Find out as much as you can about the HDTV signal in your area, and if possible speak to people locally who are receiving HDTV via an antenna, before you buy.
