High Definition Television HDTV

What is HDTV?

High Definition Television (HDTV) is an improved resolution viewing standard compared with Standard Definition Television (SDTV). Put simply, there are many more pixels with HDTV providing a clearer and cleaner image.

It is important to note that HDTV and Digital TV do not refer to the same concept. Although HDTV is available for Digital TV, digital signals can be high definition or standard definition.

Although HDTV has been around for a while and was available through analogue signals, digital signals have allowed HDTV to grow in popularity

Advantages of HDTV

Viewing your favourite shows and channels in high definition allows you to create a TV experience like never before. Compared to standard definition, HDTV provides images with sharper colours, smoother motion, and richer details.

The Future

It is likely that at some point in the future all broadcasts will be high definition, although a formal date is not set in the UK. However, once the formal switch from analogue to digital signals is completed there will be even more opportunities for HDTV technology to expand .

Viewing Requirements

To get the most out of HDTV you require an “HD-ready” television, which are becoming very common in stores. Another option is to purchase an HDTV box ) that upgrades your HD-Compatible television to receive HDTV channels.

High Definition Beyond the Television Channels

Although it is very commonly thought of in conjunction with television channels, high definition is expanding to other areas of entertainment as well. For example, HD-DVDs and DVD players are about to be launched in some markets. These video platforms will provide movie-watchers with the same amazing advantages offered by HDTV.

If you are looking to buy a home theater projector, the best place to buy one is from a store that specializes in selling them. If there aren’t any of this kind of store where you live, you can get online and look at several online stores that sell home theater projectors.

Take care when you are shopping for a home theater projector. You must have a basic understanding of how home theater projectors work so that you can be in a better position to purchase one that will exactly suit your needs. The three things you need to consider when purchasing a home theater projctor are price, brightness and aspect ratio.

Price

Good home theater projectors range between $1500 and $8000, even more. If you are on a budget, consider the BENQ PB6100, Mitsubishi HC3 or the Epson Powerlite Home 10. Each of these home theater projectors are a great way for you to start viewing movies and enjoy gaming if you don’t have the budget or can’t afford a more expensive home theater projector. However, if you have the space and the income, the Sanyo PLV-WF10 is the way to go if you want to experience the quality that larger home theater projectors can deliver.

Brightness

ANSI lumens home theater projectors set the standard for brightness.Most models generate 700 to 2000 lumens. This is considered to be the regular range for brightness for home theater projectors. A home theater projector that has 1000 lumens is all right for a dedicated home theater room because darker rooms only need about 1200 lumens. However, well-lit rooms need at least 2000 lumens because the natural light that may come in from the windows may create a glare on the screen.

Aspect Ratio

Home theater projectors can be manufactured with two different aspect ratios. The first ratio is the 16:9 aspect ratio, which is better for watching movies in letterbox format. The second is the 4:3 aspect ratio, which is designed for watching regular broadcasts. Aspect ratio simply refers to the ratio of width and height of the picture that is being viewed. The preference depends upon what you watch most on your home theater projector. For example, movies on DVD usually look better in a 16:9 widescreen format. Gamers, however, may prefer the 4:3 aspect ratio. Any way you look at it, a home theater projector is an exciting purchase.
