Buying
a High Definition Television (HDTV)
HDTV's:
Clear Picture & Better Sound
HDTV
or high definition television is the cutting-edge technology in home theater systems. Movie enthusiasts
praise the high definition televisions for its clearer picture,
better sound, progressive scanning and a wider viewing screen.
As the trend towards replacing traditional analog televisions
with the HDTV, consumers are starting to notice the eye-popping
properties of HDTV.
High definition television is a revolutionary new technology
that brings the viewer the clearest, brightest picture possible.
The picture on the television can be considered life-like
and real. The colors displayed using the digital technology and
wide screen pictures, are bright and crisp. Surround sound
further enhances the viewer’s experience.
The standard high definition television works by using a digital
broadcast signal that is able to deliver a wide-screen, high-resolution
picture with six channels of digital sound. The difference
between HDTV and conventional television broadcast is that
the high definition screen is much wider. This allows the broadcast
or DVD movies to be viewed as they would in a movie theater.
No parts of the screen either at the top or bottom are obstructed
or cut off.
HDTV
provides a wider screen than conventional TV sets. The
wide-screen format allows a more intense viewing experience
and is able to take full advantage of the field of vision.
With the prices of HDTV going down, smaller sets are hitting
the market making consumers more likely to purchase HDTV.
Another great benefit of using high definition television
is that HDTV has over twice the sharpness and clarity
of analog TV broadcasts. The color resolution for HDTV sets is far superior.
For consumers who have already made the switch to HDTV, they
feel this is the biggest advantage of high definition.
The lack of imperfections in the television screen often seen
on traditional television is another reason why many prefer
high definition to analog. With HDTV, problems such as snow
caused from a weak signal, double images from ghosting or multi-path
and picture sparkles from impulse noise are a thing of the
past. These problems often seen on a conventional television
broadcast just do not occur on HDTV.
Screen
resolution from a high definition TV broadcast is almost
five times as sharp as conventional broadcasts. High definition
has double the lines of resolution compared to a traditional
analog TV set. While a traditional analog set can only display
525 lines of resolution, HDTV technology takes this one step
farther. HDTV broadcasts can display 1080 horizontal lines
of resolution. This makes a huge difference in the picture
clarity and quality. Often with big screen analog broadcasts,
the picture is severely degraded because of the resolution
lines.
When looking into purchasing a high definition television
and broadcast provider, it is important to research
the products. HDTV comes in several sizes and varieties. Consumers can purchase
plasma, LCD (liquid crystal display), DLP (digital light processing)
or LCOS (liquid crystal on silicon), which are all types of
monitors. There are also projection displays to consider. They
also come in LCD, DLP, and LCOS. Many viewers prefer the wall
display monitor that either plasma or LCD offers. But, these
are usually the most expensive of the high definition sets,
especially the ones that are sized between 40 to 70 inches.
Lower on the cost spectrum, but equally good, are the LCD displays
that are sized at 42 inches and under.
Also,
consider the provider. High definition broadcasting
and digital should not be confused. They are not the same thing.
There are many cable and satellite companies that simply convert
standard analog broadcasts to digital to improve reception
and to provide additional services. These are not true high
definition broadcasts. Also, the picture quality and resolution
will not be the same as that of HDTV. The picture format will
not be wide-screen. Most consumers that subscribe to cable
today are getting a digital broadcast.
To keep up with the popularity of high definition, most broadcast
channels now broadcast in both analog and high definition at
the same time. There are currently about forty networks in
the United States that now broadcast in both. These include
HBO, Showtime, ESPN and the Discovery Channel. The number of
networks utilizing high definition broadcast is expected to
grow as the price of HDTV goes down. More consumers are asking
for high definition channels for their television viewing.
