Cable Television is the Norm Today
Cable
television is pretty much the standard of television use
today. Although there are still a number of basic channels
that are broadcast by radio waves in through the air, the number of
channels available in this manner has remained the same since the
1940’s. Put simply, there just isn’t enough space in the
electromagnetic spectrum to provide for a lot of different
television channels. Each television channel transmitted by
air takes up the same amount of space as many dozens of radio
stations.
With cable television, the limitation is the number of different
frequencies that can betransmitted through a single coaxial
cable. Transmitting frequencies of television by way of a
cable generally provides a lot more space, which has led to a
tremendous increase in the number of available channels. Even
better, cable television is usually received a lot better than
traditional air broadcast television. If you’ve ever owned a
TV that did not have cable, you’re probably familiar with doing the
rabbit ears antennae dance trying to get some decent picture
quality. You don’t have do that anymore with cable
TV.
Cable television costs more, as you have to subscribe for it
through a local cableprovider, but if you watch TV with any
regularity you’ll probably find the extra fee well worth it.
I’ve been a subscriber to cable television now for almost twenty
years, and I’ll never go back to the rabbit ears. Over the
years, the way in which the frequencies are transmitted through the
cables has gotten more efficient, and more channels have opened
up. Instead of getting seven or eight barely recognizable
images like you do with air broadcast TV, you get upwards to
seventy or more crystal clear channels with cable TV, depending on
where you live and who your cable provider is.
Cable television may have been the standard for some years now,
and may still be today, but it’s probably going to give way to
digital television soon. Digital TV opens the possibility for
hundreds of channels, with even better picture quality than
traditional cable TV. The good news is digital TV is transmitted by the same
sorts of cables that bring you cable television today.
Digital TV is still in its infancy, and isn’t available everywhere,
but cable television is pretty much everywhere in the United
States, Canada, Europe, East Asia, and is in most of Australia,
South America, and parts of the Middle East.
