Eye-popping Properties of HDTV
from: Gregg HallHDTV 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.
