Looking to replace your old TV? Then you may might to invest in the new HD technology. Unlike regular standard televisions, HDTV sets are much lighter, occupy less space, offer more features and provide better image quality. However, the search for a new HDTV can be a daunting one, especially for new customers who are unfamiliar with the many HDTV technologies. Hence, in this article we will examine the various types of HDTVs and their benefits.
HDTV CRT
HDTV CRT is based upon on the old Cathode Ray technology which is found in regular TVs. Some of the benefits of this technology is its proven reliability (50+ years), picture quality and low price point. However, with this technology you have to deal with bulky, heavy TV sets, screen glare problems and limited widescreen choices. The biggest wide screen you can get for a HDTV CRT is only 34-inches.
Rear Projecting HDTV
Currently there are two types of Rear Projection HDTVs. The older Rear Projection HDTV is based on the CRT technology while the newer one is based on the LCD/DLP/LCoS Projection technology. Like HDTV CRT, Rear Projection CRT offers large wide screens at a very low price point. However, you have to deal with poor picture quality from non digital signals, expensive maintenance, bulky cabinet enclosures and narrow viewing angles. The newer LCD/DLP/LCoS Projection technology offer larger screen sizes, good black levels, larger viewing angle, and great picture quality. However, with this technology you have to deal with expensive bulbs that have to be replaced every 5,000-7,000 hours.
Plasma HDTV
The Plasma HDTV is a mainstream technology for viewing high definition channels. Plasma HDTV displays offer amazing color definitions, large viewing angle, good black levels and they occupy less space. However, with this technology you have to deal with the possibility of screen burn-in problems and screen glares.
LCD Flat Panel HDTV
The LCD Flat Panel HDTV is the other mainstream technology for viewing high definition channels. LCD HDTVs offer wider range of screen sizes (7" to 65"), greater image resolutions, are very bright, no burn-in problems and last very long (60,000+ hours). However, with this technology you have to deal with poor black levels, small viewing angle and a high entry price point.

Should You Make The Switch To HDTV?
Many people are familiar with HDTV and want to have it in their homes, especially with football season here now! When looking for a new HDTV set it is important to take your time and compare television models. Do your research and arrive at the store prepared with all your questions. High definition television is extremely popular because you get a clearer picture, increased sound quality, progressive scanning, and a wider viewing screen that makes it look like the action is right in your living room.
The Big Screen
A typical HDTV is a big screen television and can be quiet expensive. A variety of smaller screened televisions that are HDTV capable will be on the market in 2007. Although HDTV is becoming more and more popular only 30 million televisions in the United States are using a digital tuner.
Choosing Your Television
Before you even begin shopping for your television you should spend some time researching HDTV and understanding the important aspects of this type of television. You should also take your time and shop around before making such a costly purchase. Because the current HDTV sets are large screens they are usually expensive. Personally, after having a 55 inch TV for 10 years now I could never go back to a small television.
Consumers can purchase several varieties of HDTVs including:
Plasma
LCD-Liquid Crystal Display
DLP-Digital Light Processing
LCOS-Liquid Crystal on Silicon
Projection Displays which come in LCD, DLP, and LCOS
The Three Types
Digital television signals are currently broadcast with three main types of signals.
SD-Standard Definition which can be broadcast through a regular square television screen
ED-Enhanced Definition which is also capable of being broadcast with a traditional screen or in a wide screen format
HD-High Definition, which is only wide-screen but offers a clearer crisper picture.
No matter which type of television you are looking at getting you will have many sizes to choose from as well as many different styles.
Benefits
The sharpness that comes from an HDTV is twice as much as a traditional television set and clarity is also extremely enhanced. A HDTV set has a high color resolution, which is often the biggest visible benefit of these televisions. High definition television also tends to lack the imperfections that an analog television screen might have. An HDTV will not have snow or other signal problems that are usually associated with an analog television. Other benefits of HDTV include:
A screen resolution at five times conventional broadcasts
Double lines of resolution instead of single resolution
1080 horizontal lines of resolution
No picture degrading on larger screens

HDTV - HDTV Explained
You have probably heard of HDTV but you may be confused by all of the new terminology.
The maximum resolution on a standard analog TV is 720 X 480 pixels, which is about 337,000 total pixels. HDTV is part of the Digital TV specifications which has many different video resolutions. The two main resolutions to be concerned about are 720p and 1080i. The "p" means progressive and "i" mean interlaced, in both resolutions every second has 60 frames of video.
Progressive resolution puts 60 full frames on the screen every second. Interlaced resolution puts 30 frames of only odd lines and then 30 frames of only even lines up every second. Some people find that the interlaced video causes flickering.
The 720p video resolution is 1280 X 720 pixels, which gives 921,600 total pixels and the 1080i video resolution is 1920 X 1080, which gives a huge 2,073,000 pixels.
It is personal choice as to which resolution you prefer, the best way of finding out is to go down to your local retailer and look for yourself.
The sound on HDTV will sound better than it did on your analog tv, some HDTV programs include Dolby Digital 5.1 surround sound, but you will need the relevant speakers to be able to take advantage of this.
You will have to buy a new HDTV. Some HDTVs come with built-in tuners, while others do not. The tuner converts the signal into something that your TV can recognize. HDTVs that do not come with a tuner are commonly called "HDTV Ready." An HDTV without a tuner is worthless.
It is possible to view HDTV on your pc, you can do this with ATi HDTV Wonder, it comes with its own antenna to pick up airborne HDTV signals, it also has inputs for cable and satellite signals. A benefit of this is that you can play and record any show you want on your computer. Find more information at http://www.whathdtv.info

How To Get HDTV Programming For Your Home
OK, so you have your brand new HDTV or are seriously thinking about getting one soon. That's a great decision because this new television technology is going to quickly become the standard for broadcasting television signals. In fact by 2007 all television broadcasting will have switched over to digital format under the direction of the FCC, and that paves the way for high definition television to become the accepted norm.
So how do you actually get the HDTV signal then? Well, there are different ways to do that and the best decision for you probably depends most on where you live. If you live in close proximity to television stations that broadcast HDTV programming then all you will need is a television that already has a HDTV tuner built in to be able to receive and display high definition broadcasts, and a suitable antenna. However, you will be limited to receiving only a small group of local stations.
For most people, the best solution is to become a subscriber to either a cable TV or satellite service, because they offer many more channels of entertainment and news that broadcast in HDTV. To receive the signal from these providers you only need to have a television set that is HDTV "capable", or in other words, all that is needed to process high definition programming is an external receiver or tuner. Just like the ones provided by cable and satellite companies.
The other advantage of having the HDTV capable television set is that as the technology improves, you can simply upgrade the receiver as your programing provider makes the new tuners available, usually at very little or even no cost since you continue to use their service.
You can also use cable or satellite service if you have the HDTV tuner already installed inside your TV, but why pay for the tuner if you get the same thing from your programming provider instead?
So in summary, you can get HDTV programming either by antenna through local TV broadcasts, or broaden your channel selection and HDTV choices through either a satellite or cable TV company.
