Because it is still relatively new, HDTV is a lot more expensive than regular TVs.

So, considering the expense, it would be wise to learn about HDTV technology and equipment before spending a lot of money on a new setup. And even if you have a HDTV, don't assume that you can get HD signals. That is dependent on your satellite or cable provider.

If you live in an area that doesn't have any providers that offer high definition services, then buying an HDTV system is like getting a Ferrari and not being able to put gas in it.

The Providers

The two main television providers that offer high definition services are cable and satellite. There are some new companies that are now offering high definition service over the internet (called IPTV, for Internet Protocol Television)and these are growing in popularity.

Comparing cable and satellite, satellite TV has, in general, the advantage when it comes to high definition. Because satellite providers already broadcast their signal in a digital format, and because they have been doing so for longer than most cable providers, they got an early jump on high definition.

There are certainly cable providers out there who provide high definition services that can rival or beat some satellite providers, but as a whole, the satellite market is on top for high definition.

Before you invest in an HDTV setup, make sure that your provider offers HD programming that you're interested in. If they only offer a few movie and sports channels, and you don't like movies or sports, then look elsewhere.

The Equipment

First thing to do is check out the receiver from your satellite or cable company. The newer generations of these receivers will have different output options, and this mill help determine what kind of TV you get. Some older boxes will only have component or coaxial output, but these cannot transmit HD signals, so you'll have to get a new receiver if those are the only options you have. Ask your provider about an upgrade.

Match your TV to the outputs. At the moment, the best one around is HDMI. These outputs transmit both video and audio at the same time and provide for great clarity. Big screen TVs that feature HDMI capability are more expensive than those that don't, though, so be warned.

The TV itself, aside from making sure it can interface well with your receiver, will largely be determined by the room its going in to and the size of your wallet.

Pick out one that fits the constraints of both and you'll be enjoying high definition television in no time.
