Receiver Readiness for HDTV
HDTV or high definition television offers many benefits over traditional analog
television. High definition television has excellent digital superiority, crisp
detail, progressive scanning, digital audio, a wider viewing area and better
quality DVD playback. However, the days of simply plugging a television into an
outlet and calling the cable companies are over. Now, you must make sure your
television is compatible with the type of service you want.
When you are ready to receive HDTV service you first need to check into a few
things before making the switch. If you have a traditional analog television,
you can receive digital broadcasts by purchasing a converter for your
television. The converters for enabling traditional analog televisions to
digital cost around $100. The picture resolution will not be the same, but you
will still be able to see the broadcast.

he can’t understand it, what is the point of writing it?
More and more consumers are getting connected to high definition. As the
technology to make smaller HDTV sets rises, the cost of these televisions come
down enabling more people to purchase the sets. In addition to the cost of the
actual television, the price of enhanced cable or satellite service must be
considered before getting connected to HDTV.
High definition does have its benefits besides a better picture resolution. HDTV
has none of the imperfections caused by a traditional analog broadcast. There is
no snow from weak signals, no double images from ghosting and no picture
sparkles cause by impulse noise.
Screen resolution from a high definition TV broadcast is almost five times as
sharp as conventional broadcasts. High definition has double the lines of
resolution compared to a traditional analog TV set. While a traditional analog
set can only display 525 lines of resolution, HDTV technology takes this one
step farther. HDTV broadcasts can display 1080 horizontal lines of resolution.
This makes a huge difference in the picture clarity and quality. Often with big
screen analog broadcasts, the picture is severely degraded because of the
resolution lines.
To get your home ready to receive high definition television, you must first
purchase an HDTV-ready or an HDTV capable television. 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.
The next step in receiving high definition service is to acquire a converter
box. A converter box usually costs between $5 and $10 per month, or some are
available for purchase for several hundred dollars. Many HDTV sets available on
the market now have built-in digital tuners that allow you to view the free
digital broadcasts of major local networks. Additionally, converter boxes that
are compatible with analog televisions can be purchased. These special converter
boxes or adapters cost around $100. The picture will be similar to analog, but
will be in digital format. The only downfall to this is if there is a weak
digital signal, there could be no picture on the screen at all.
Next, when converting to HDTV, you must make sure that the channel you want to
watch is broadcast in high definition. All major networks currently broadcast in
both analog and high definition, but not all of their programming is in HDTV.
The FCC recently gave networks channels in both analog and high definition with
the hopes that networks would also make the switch to all HDTV. Besides the
major networks, many of the movie channels also broadcast in high definition. Be
aware that not all channels do broadcast in high definition, so if you have
favorite channels it is important to call your cable or satellite provider
beforehand to see what is and what is not offered. Some who receive high
definition television are sometimes disappointed to learn that while all the
major networks broadcast on a high definition channel, not all programs are in
HDTV. Most networks will broadcasts popular sporting events and primetime
specials in HDTV.
