HDTV as a Glorified PC Monitor Why Bother
With high definition television becoming increasingly popular, many consumers
wonder if the extra price for an HDTV set is worth the money. After all, many
critics of the HDTV say it is just a glorified PC monitor so why bother? Here
are reasons why consumers should take a second look at high definition
television before making the next television purchase.
The technology for high definition has been around for years. The Japanese were
the first to perfect high definition back in the 80s. The United States wanted
to get in on the “high definition race” and several American companies
formed a “Grand Alliance” by inventing digital HDTV.
As a result, the FCC announced that all analog televisions in the United States
would become obsolete by 2006. Consumers and broadcasters would have to make the
switch from analog to high definition. To give the broadcasters a nudge, the
government issued every network a high definition channel to be used alongside
their traditional channel.
The idea was to give television broadcasters additional channel space to
broadcast in both analog and digital. The old channels would then become
obsolete. To make this work, all televisions would have to convert to digital.
All televisions made since 1946 would suddenly become obsolete unless a
converter was purchased and installed.
Now, as the switchover date approaches, many companies are giving consumers more
choices in HDTV. When high definition first arrived on the market, the
televisions were usually very large and very expensive. Smaller and less
expensive high definition sets are becoming more available to consumers.
There are many advantages to HDTV. There are real advantages of high definition.
The picture definition of HDTV is about twice the vertical and horizontal
picture resolution of analog televisions. This makes the picture twice as sharp
as tradition television. Another advantage of HDTV is that it has a screen ratio
of 16:9 as compared with analog television which has a ratio is 4:3. There is
also less ghosting and dot crawling on an HDTV screen. HDTV can also be
broadcast in wide-screen and has superior audio to analog stereo audio.
For true home theater buffs, high definition is preferred because it works very
well with a good surround sound audio system. Also, the new DVD movies that are
available today work better with high definition televisions. On a traditional
television, the movie is cut off at the top and bottom of the screen. This is
not the case with a high definition set. No part of the movie is missing, giving
the viewer a truer viewing experience. Movies can be viewed as they are in a
theater, the way moviemakers intended.
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.
It is important to do some research into high definition products and available
broadcasts before making a large purchase. While most channels do offer
broadcasts in HDTV, not all shows are available. Some networks often offer
viewers certain prime time specials and sporting events in HDTV rather than
their entire broadcast. The four major networks usually offer professional
football, championship baseball, basketball and NASCAR in high definition. In
addition, they offer television specials and awards shows in HDTV.
To view any high definition broadcasts an HDTV-ready or an HDTV capable
television must be purchased first. There are several to choose from. Rear
projection, plasma and LCD are all types of HDTV. When a television is labeled
as HDTV-ready that means the TV has an HDTV tuner built in. This enables the TV
set to get over-the-air high definition signals from local networks.
HDTV-capable means that the TV set is able to receive high definition signals,
but only with the use of an HDTV converter box that is available from the cable
or satellite company, or a digital tuner and over-the-air antenna. A converter
box usually rents for $5 or $10 per month, or some are available for purchase
for several hundred dollars.
