The Wide Screen Appeal of HDTV
HDTV, also known as high definition television is becoming more popular because
it offers viewers a clearer picture, better sound, progressive scanning and a
wider viewing screen. Widescreen televisions sets are a top choice for consumers
looking to set up a home theater system, too. With the FCC pushing to make a
switch to all HDTV, consumers are beginning to see the wide screen appeal of
HDTV.
Digital broadcast is slowly emerging for television. Because of the 1990
announcement by the FCC that all television sets be converted to digital by
2006, many broadcasters and television manufacturers are making the switch.
Converting to all digital was originally prompted by the thought that digital
television will provide a better viewing experience and free up broadcast
spectrums. These spectrums will then be used for emergency communications for
first responders. The government has tried making the switch to digital easier
for broadcasters by giving them simultaneous channels to broadcast in both high
definition and analog. Many broadcast channels now broadcast both ways.
There are three types of digital television signals that currently broadcast.
They are SD for standard definition, ED for enhanced definition and HD for high
definitions. The SD and ED signals can be broadcast with a traditional square
screen or in a movie-like widescreen with reduced picture quality. HD signals
however, are all widescreen, which makes the picture crisper and clearer.
When shopping for a HDTV, there are many sizes and styles to choose from. LCD
microdisplays are probably the most popular of the HDTV sets. It is a rear
projector that uses three small LCD panels. Each panel is less than one inch
diagonal and has the capability to produce high definition wide screen images up
to 70 inches. The LCD panels are made up of a grid of transistors that create a
pixel structure. When the transistors are charged, tiny rotating crystals
suspend in a liquid inside the panel. The crystals are like tiny shutters that
control the amount of light that passes through each panel. The light is
reflected on a mirror and through a projection screen, which creates the full
color high definition picture.
Direct View CRTs and Microdisplays are two other types of televisions using high
definition technology. A direct view CRT is a traditional type television with a
picture tube that is updated to display high definition images. They are
available in widescreen. A microdisplay is a rear projection television with a
depth of less than 20 inches. They come in LCD, DLP, and LCoS.
When choosing a high definition television, consider the size of TV bases on the
resolution. Check to see how far the TV set will be to where the viewers will
sit. There are ideal distances to see the picture resolution. For example, for
optimal viewing, a high definition widescreen that measures 50 inches should be
viewed at about 117 inches, or just less than ten feet from the screen.
HDTV widescreen televisions are becoming popular choices for consumers wanting a
movie theater-style viewing experience at home. Imagine sitting in a home
theater with a large, clear screen and surround sound. With HDTV widescreen TV,
it is possible.
There are several benefits of HDTV widescreen, making it a top choice for movie
lovers. HDTV widescreen sets enable movies to be seen as the filmmaker intended
them. It appears as it does in the theater and the viewers see every bit of the
movie that is intended. With widescreen, the TV screen cuts off no part of the
image, either at the top or the bottom. Widescreen shows the colors and lighting
correctly. The viewing ratio is not distorted as it often is in a regular
television screen.
The drawbacks of widescreen are few, although there is a couple. For one, the
image on the screen is sometimes smaller. The film images may show less
resolution on a widescreen. The benefits of a clear, crisp picture, superior
audio and wider viewing area far outweigh the negative.
Consumers will appreciate the high quality of the widescreen. Also, widescreen
televisions often take up less space than a traditional TV, making it perfect
for small theater rooms. Most DVD movies now that are available for purchase
come formatted in the widescreen version, making it work hand in hand with the
television set.
