Do you know what an HDTV is? If you don't, it stands for high definition
television. In fact it will be quite some time before this technology
is outdated. In general, HDTV televisions come in different types and
sizes. There 3 different types of HDTV's are (CRT)direct view TV's, Flat
Panel Plasma or LCD's, rear projection TV's and home theatre
projectors.
The first one is something that is being phased out
because it is too bulky and is rarely PC compatible. Since it is going
away, there is no point in talking about it any longer so we move on to
the next one which is which is the plasma and the LCD television. Both
of these are selling fairly well in the market despite its expensive
price tag. To give you an idea, you could be paying something from £150
to almost £3000 to have one of these inside your home.
But why is
it so expensive? Because of the technology used which makes these units
sleek and flat. It also promises to give you crystal clear pictures and
audio which makes you feel like you are watching a movie as though you
are inside a theatre. Then you have the rear projection televisions
which are getting rarer. You can find a screen between 50 to 73 inches
in the market with a price range from £1000 to £3000. But why go for
that when companies are now working on bigger screens for the plasma and
LCD which are much better to own?
The home theatre projections
are also a thing of the past thanks to the plasma and LCD televisions.
This is why just like direct view televisions, it is not worth talking
about any more especially when there is no longer a demand. This bring
us now to the question, can we just bring the HDTV home, plug it in and
then start watching anything on it? The answer is no because you need to
get a television signal in order for pictures to appear on the screen.
For that, you will need an HDTV source, an HDTV channel, and the HDTV
show itself.
The HDTV source comes from your cable or satellite
provider. Once you sign up, you will get a cable or a box which is
connected to your television. Of the two, the satellite is more
expensive because apart from the box, you need to put a satellite dish
outside your house.
Some shows on television now broadcast on
high definition so you need to flip to that channel to watch on that
format. Is it different from watching without high definition? Not
really but it won't be long that other networks follow suit so you
should already be ready for it. High definition is truly changing the
way we watch whatever comes out of the tube. Aside from television
shows, you will notice that this is also happening to the DVD's that you
purchase.
