Buying
a High Definition Television (HDTV)
HDTV's:
It's All In The Picture
HDTV (also known as high-definition television)
has created quite a splash in today’s world of home entertainment.
HDTV has amazing visual clarity as well as the unique
sound of digital that is without a doubt, unequalled by anything
else. The broadcasting of the signals of high-definition television
has a much higher resolution and is more advanced than more
traditional television signals (including NTSC, PAL and SECAM).
To look back in history, “high-definition television” was also
a term used to relate to standards of television that were
put in place during the 1930’s to replace the television systems
that were more elementary and experimental in nature. Image
means everything in the HDTV world.
HDTV is broadcast in digital format (with the exception of
the earlier analog formats that were prevalent in both Europe
and Japan). The creation and introduction of HDTV is often
thought to go hand in hand with the beginnings of DTV, or what
is known as digital television.
To return to the mention of Japan, HDTV was in the works for
a number of decades but once it was implemented it took place
in an analog format. The system they once avidly subscribed
to is not in the least compatible with the necessary standards
that digital dictates. In Japan the broadcasting of HDTV began
in December 2003 and was made possible by ISDB-T. In fact at
the present time, Japan is the only country that broadcasts
its services in HDTV. Since that time an estimated two to three
million receivers for HD have been purchased in Japan.
Image counts for a lot in Europe as well. Its pioneering work
in the transmitting of HDTV began in 2004 and started off with
Euro 1080-HD1 (its flagship channel). Since last year, HD2/HD5
has been added. HDTV is only beginning to gain headway in the
European countries. The channels that broadcast HDTV in Europe
are all available only with a subscription and no plans are
in the works to alter this any time soon. It will only be a
matter of time before television viewers in Europe have access
to a variety of FTA HD channels. Plans are pending for this
development.
The
concept for the development of HDTV derived from movies
viewed on a wide-screen. Movie producers gleaned from moviegoers
that a movie screen that covered a larger width of space and
took into account peripheral vision would improve upon the
entire movie going experience. The image it portrayed was that
bigger was, in this case, indeed better.
A wide-screen at a movie theatre could also be developed in
the home entertainment field. This began to take shape in the
early 1980’s when movie producers were presented with a system
of HDTV that both Sony and NHK had been working on since the
1970’s. The system that had been developed produced images
that greatly resembled the specifics of 35 mm film. The system
was referred to as NHK Hi-vision.
High-definition television allows a film watched on a television
screen to remain at the width it would also be on a standard
movie screen but all features are enhanced. Scenes of island
paradises, thunder and lightning storms, car races, sporting
events, fireworks displays and thrillers with suspenseful moments
all came to life so much more than ever before with the creation
of HDTV.
Media images of HDTV are becoming more and more prevalent
and Sony is no longer the only store to carry a full line up
of HDTV sets. You shouldn’t have to look too far in any given
electronics store to find HDTV screens looking back at you!
It is one of the fastest growing trends in the electronics
industry today.
The
advantages inherent in HDTV including the improvements
in sound and picture quality are catching on more and more
all of the time. The very first station in the United States
to broadcast HDTV was WRAL-HD located in Raleigh, North Carolina.
Since then many big cities throughout the U.S. have followed
suit as HDTV stations are becoming not just the wave of the
future but also the reality of the present. A nationwide mandate
has been put out by the Federal Communications Commission (abbreviated
to FCC) for all television stations to have it within their
ability to be able to broadcast television in the digital format
as early as the year 2007.
