If you love visual entertainment on the cutting edge, HDTV - or High
Definition Tele-Vision gives you a preview of the future; images and
sound that is so real it takes you into the experience. High-definition
television takes digital television or DTV to the next level. Or least
that is what we have been promised. When the first HDTV announcement was
made in 1998, high-tech fans along with movie buffs anxiously awaited
its release. But several years have passed since the introduction of
this technology for many people it has failed to live up to their
expectations.
Part of the problem is that HDTV, analog and
digital terms have a lot of people confused. As the United States
broadcasters move closer to the date where their signals must be
converted from analog to digital in 2009, consumers should be aware that
purchasing an analog television should include DTV or digital
television signal capability so that they can continue to receive
television programming.
As United States broadcasters work
through the conversion period from analog to digital television, the
signal transmits the information for the video and sound in binary code
instead of a wave; using the UHF portion of the radio spectrum with a 6
MHz bandwidth, the same as analog TV signals. Digital television or DTV
provides the viewer with several advantages:
Smaller sized televisions receive pictures and sound with better quality
Larger television screens benefit from digital signals ability to deliver higher resolution
Television stations can broadcast several signals using the same bandwidth
Interactive content or additional information can be broadcast along with the DTV signal
Digital TV supports high-definition television broadcasting
When
the conversion from analog to digital broadcasting is completed,
without a DTV decoder in your analog television set you will need cable
or satellite service to be able to watch television programming. HDTV is
just one part of the digital conversion from analog broadcasting.
But
to fully experience HDTV you will need more than just your television;
the broadcaster must use a high-definition signal and beside the HDTV
set, you will need a receiver and an antenna to receive the signal. DTV
uses MPEG-2 encoding, the industry standard for DVDs. As you begin to
shop for a high-definition television set you will have several options:
An
HDTV ready set which is also called an HDTV Monitor. This type of set
will not have an HDTV tuner instead they use an NTSC tuner so that you
can continue receiving analog television programming.
An
integrated HDTV which includes a digital tuner (also known as an ATS
tuner) built in to the set itself. You will be able to watch
high-definition television broadcasting by attaching an antenna to the
set.
HDTV sets have either one or two native resolutions in order
to scale the signal to match its resolution capability. It is good idea
to consider what type of programming you watch most to select the best
native resolution; movie fans should look for television sets with the
highest resolution display while sports action fans should choose the
highest progression frame rate. HDTV is simply the highest level of
digital television available; as more broadcasters convert from analog
to digital television, having the right equipment is what will make the
difference in your television viewing experience.
HDTV is the new
age of television, more and more people discover the advantages of high
