Digital vs Analog? Analog
vs Digital? What’s the big deal about the switch in signal to your TV?
There have been no bigger advancements
in technology over the last 20 years then what is happening in the television
industry. Only 10 or so years ago the price of flat screen TVs were
astronomical and were only affordable by wealthy individuals. Fast forward
to today’s retail economy and a quality flat screen TV can be found for well
under $500. With these new TVs comes the world of high definition that
broadcasts sporting events, movies and television shows with a much clearer
picture then televisions of the past. With the broadcast of events in
high definition (HD) comes the need for a better broadcasting system, this is
where digital TV service has come in and revolutionized the cable TV industry.
Let’s take a further look into the
Digital vs Analog TV comparison
Advancements in Technology
Up until the past few
years, commercial televisions sets have all worked from receiving analog
signals. With analog, televisions receive radio frequencies that were sent
out from a variety of TV stations. Each TV station emits a frequency that
corresponds to a channel number. With this technology analog TV sets
received a constant signal to their antenna that would change when they
switched channels.
On the other hand, digital signals work
much like computers. Instead of using a radio frequency, the digital
signal is sent out in a series of 1s and 0s. Any television with a digital
tuner will receive this information and will generate the picture and sound
onto their TV.
Quality of Programming
Every one of us who are older than 30
can remember their analog signal from when they were young. While some of
the higher quality channels came in with good picture quality most of the time,
there were many channels that had the snowy or fuzzy look on the TV
screen. This problem has to do with the type of signal transmitted from
the different stations. With the analog signal the quality of the signal
was determined by the strength of the analog signal, the antenna’s proximity to
the television station and possible obstructions depending on where your TV was
located. A weak analog signal constituted a poor picture for the
viewer.
With the digital signal, things like
proximity and obstructions will not have any effect on the picture. With a
binary signal, the broadcast is not only higher quality then the analog signal
but the picture will not have has any of the graininess of the analog
picture. The only problem that a digital picture may get is a momentary
freezing of the picture if the signal gets interrupted. While this was
more of a problem with the early digital ready TVs, this technology has been
improved upon in the last couple of years to almost be non-existent.
High Definition (HD) TVs
One of the main reasons that the analog
vs digital programming has become such a discussed technology is the recent
availability of HD TVs to the general population. Sporting events, movies and
cable shows show the true value of digital programming as their HD channels are
a clear upgrade from “regular” cable channels. From their initial release
to present day the pricing of high definition televisions has dropped
tremendously. For instance a 32” TV may have costs $2,000 dollars in 2003
and now the same size 32” LED TV with much
better features can be found for under $400. With these pricing changes
businesses can now afford to add digital ready TVs at low costs.
Overall
Digital vs analog is something that
will not even be debated 10 years from now as technology will keep pushing
analog technology further and further back. As of 2013, most satellite TV
providers will no longer offer analog channels. With this change more
businesses will look to add the LED, commercial grade TVs to their businesses
while sending the old analog TVs to the recycle bin.
