HDTV The NEW Must See TV
There are two different digital formats for TVs. One is SDTV, which means
Standard Definition TV, and HDTV, which is the newest in TV technology. This
must see new TV gives the SDTV a new look. The picture is so much clearer,
sharper, and almost three-dimensional. HDTV has lifelike pictures and theater
sound. It has a high resolution, which gives astonishing clarity. It’s
sharper, wider and more like a theater screen than a TV set. It is as clear as a
computer monitor as it uses the same technology. Since most of us are use to the
sharpness and clarity of our computer monitor, it means that we want the same
technology when we watch our TV. This computer sharpness has to do with the
amount of pixels used on a computer monitor. The lowest resolution is 640 x 768
pixels. Some monitors go as high as 1024 x 768.
Pixels are actually two words jammed together, ¾ picture and element. It’s a
tiny sample of video information and these tiny pixels are what make up the
overall picture. A pixel per inch is the measure of sharpness on a television
display screen. Resolution is based on the number of pixels displayed. One form
of high-definition picture formats is composed of 1080 lines and each line has
1920 pixels.
This digital encoding system provides a sharp, clear picture. This encoding
could soon make analog television sets obsolete. Once you’ve seen for yourself
the clarity, depth and resolution of an HDTV you will want one. Many of the new
satellite systems use digital encoding systems and then have to be converted to
the analog format to fit your present TV. It looks great, but would look even
better if it didn’t have to be converted at all. Digital signals can be
broadcast over the air, by cable, or transmitted by a satellite system to your
home. It’s then directed to your digital ready TV for clear and sharp pictures
and terrific surround sound.
HDTV has the highest digital resolution of the new digital TV’s. Right now,
you are only seeing about 525 lines of resolution on your present analog TV. An
HDTV with wide screen format has lines from 720 to 1080.
The usual TV set has a picture resolution of about 210,000 pixels. On HDTV sets,
each picture contains around two million pixels. What does this mean to you? It
means a picture with about ten times more detail than on a standard analog TV.
This means wider images, more detailed picture, and Dolby surround sound, just
like being at a movie theater. The HDTV movement has revolutionized the TV
industry, much like it was revolutionized when they converted from black and
white to color. Previously only the very rich could afford to put a home theater
in their residence. Now with today’s digital technology and sound, the average
person can experience the thrill of having your very own theater. The wide
screen format changed the movie audience experience and it now it is changing
the home TV experience.
The wide screen allows for a panoramic view that fills our field of vision
because our eyes are located side by side. It lends itself to more innovative
video compositions and allows directors to compose shots that captivate and pull
the audience into the movie or the playing field.
This new technology will demand changes that can be costly for the viewer and
for the TV stations and media production companies. Newer technology means newer
equipment and that translates into more expense. However, just as the new
technology of CDs, VCRs and DVD players, the prices will eventually fall.
As of May of 1999, the Federal Communications Commission decided that digital
television and HDTV should be the newest standard for broadcasting. The change
over has begun with the FCC requiring the top TV networks to broadcast a digital
signal in the ten biggest markets.
The networks plan to phase out all analog TV broadcasts by the end of 2006. Your
TV won't be obsolete, but it will definitely not be the newest technology you
can enjoy. After you have seen a movie or a sports event on HDTV, you'll be
ready to make the big switch. Research the subject and know what you're looking
for when you go to make the purchase.
