HDTV - High Definition Television HDTV is no longer a technology of the future. It’s here
now, bigger and better than ever. And there’s never been a better time to make
the move to high definition. Prices have fallen significantly, and there’s
more HD programming options than ever before. Practically everything you’ve
been accustomed to watching in the past is now available in stunning high
definition. What
is High Definition TV? The old, traditional broadcast TV system depended on signals
that were analog in nature. Advances in technology over the last several years
have introduced the capability of sending a new type of TV signal that is called
digital, or High Definition. This signal offers the capability of a dramatically
better, stunning picture, and much better sound. The HD terms you hear such as 720p, 1080i or 1080p refer to
the number of scan lines that the TV can display. Traditional analog TV pictures
were made up of about 480 horizontal lines of resolution. These are the small
scan lines that actually make up the picture that your eye sees. This is
commonly referred to as a 480i, for 480 lines. The “i” refers to the fact
that the lines are interlaced, meaning the lines are displayed alternately. High
Definition TV offers many more lines of resolution – thus the reason for the
incredible picture clarity. HDTV also makes it possible to display the lines
progressively, or without having to alternate them. This enhances the clarity
even further. Basic High Definition is referred to as 720p, meaning 720
lines of resolution displayed progressively. But that’s only the start. Full
HD has 1080 lines. Broadcast signals go up to 1080i, but there are now new
products such as high definition DVD’s that are displayed at 1080p. Thus,
1080p is the ultimate High Definition picture – requiring the most advanced
electronics. American carries an unbeatable selection of all different levels of
HDTV’s. Once you see the stunning clarity of HDTV you’ll see what all the
buzz is about. If you’re a sports or movie enthusiast, once you’ve seen your
favorite in HD, you’ll never want to go back!
Previous TV's had a width-to-height ratio of 4:3, meaning
they were more square-like in shape. Today’s new HDTVs’ aspect ratio is
16:9. This wider screen format far better accommodates sporting events and widescreen
movies, making the HDTV experience even more spectacular. Size
Matters, and So does the SOUND! Different
Types of HDTV HD
Flat Panel TV's These are the thin, sleek TV's you see that can hang right on
a wall. These TV’s offer the widest viewing angle and the highest contrast.
There are two basic types of flat panels. LCD (liquid crystal) TV’s and Plasma
TV’s. Plasmas are generally larger screen sizes, while LCD can be large or
small in size. Small or mid-sized LCD’s are a great option for countertops,
dens, kitchens and baths. HD
Advanced Micro Displays These TV's offer a slim, lightweight design and advanced
technology without the expense of flat panels. All are HD Ready or HD Built-in
and offer large screen sizes, a wide viewing angle, high contrast, and have a
replaceable light source. Front
Projectors These giant screens are generally used for wall-sized
displays of approximately 100” or larger. Unlike older projection systems,
advances in technology now allow the stunning clarity of High Definition to even
be seen on these huge screens. You’re seat on the 50 yard awaits! See
the difference for yourself! American's commitment to HDTV goes far beyond simply having
the finest selection of brand name HDTV's on display. At American, customers can
step up and see everything High Definition has to offer. Experience firsthand
the incredible difference in clarity, resolution and color that HDTV's 1080
lines of resolution provide. You'll hear and feel the awesome sound an HD signal

forget the HD Signal Once you've made the decision to purchase your new HDTV,
remember that to experience that stunning High Definition picture in your home,
bringing in the HD signal is the next key step. This can be accomplished through
an HD over-the-air tuner, satellite tuner, or in many markets, HD cable.

Programming - It's HERE and more is on the way! There has been a significant increase recently in the amount
of available High Definition programming. The major networks now simulcast in
high definition with most local affiliates also sending out this signal. Over
70% of the networks prime-time lineup is now produced and broadcast in stunning
High Definition. In addition, the pool of HD programming available via satellite
or cable has now expanded to include networks such as HD Net, HD Net Movies,
ESPN HD, TNT HD, Discovery HD, HBO HD, Showtime HD, INHD, Cinemax HD and more.
Specials, movies, sitcoms, and all kinds of sports are now broadcast in stunning
HD. For sports fans, most major sporting events are now broadcast in High
Definition – putting you in the middle of all the action. When
will all signals be digital? The target date for going to all digital broadcasts is
somewhat of a moving target. According the the FCC, the target date for the end
of the transition from analog to digital television signals is February 17,
2009. If that date holds, at that point broadcasting the current
"analog" channels will end and that spectrum will be put to other
uses. Until the transition to DTV is complete, television stations will continue
broadcasting on both digital and analog channels. HD
Players Yes, it’s now possible to have a High Definition player
connected to your HDTV. And they, too, are becoming more affordable. There are
currently two formats competing for this market. HD-DVD and Blu-Ray. HD-DVD
movies have been releases on each format currently, and only time will tell if
one format will win out or if they are destined to co-exist. Most of these new
HD-DVD’s are being released in 1080p. So, if you are a movie buff who plans on
taking advantage of this new technology, make sure your new HDTV also has 1080
capability. Can
I record HD programming? Digital
television Quality Levels There are many quality levels of digital television
programming. The most common are: Standard
Definition TV (SDTV) -
SDTV is the basic level of quality display and resolution for both analog and
digital. Transmission of SDTV may be in either the traditional (4:3) or
widescreen (16:9) format. Enhanced
Definition TV (EDTV) -
EDTV is a step up from Analog Television. EDTV comes in 480p widescreen (16:9)
or traditional (4:3) format and provides better picture quality than SDTV, but
not as high as HDTV. Consumer
Alert TV
equipment with only an analog broadcast tuner will require a converter box after
February 17, 2009, to receive over-the-air broadcasts with an antenna because of
the Nation’s transition to digital broadcasting. Analog-only TVs should
continue to work as before with cable and satellite TV services, gaming
consoles, VCRs, DVD players, and similar products. For more information, call
