Cable and Satellite are two
technologies that are used in the
television industry to broadcast their
shows. Cable is becoming
progressively obsolete, as Satellite
technology becomes more available.
Satellite technology is the more
dominant of the two technologies and
usually fills the gap in areas that do not
use cable television.
Satellite TV works by receiving signals
from a communications satellite in
space to a ‘satellite dish’ outside of the
house. Cable TV works by sending
programs to the consumer by way of
radio frequency transmitted through
optical fiber cables. Optical fiber
cables use thin glass threads that
transmit information at extremely high
speed, with extreme efficiency.

Digital is now taking over
Analogue with the new ‘Digital
Switchover’ that will be
sweeping the UK soon. During
this Switchover, all Analogue
transmitters will be deactivated
and replaced with more
efficient Digital ones. Before
this switchover, Local Relay
Emitters could only send out
Analogue signals, only giving
five available channels,
upgrading to Digital would
increase this five to fifteen
available channels, increase
signal strength and send out a
Digital signal as opposed to an
Analogue one.

High Definition Television is a
fairly recent technology starting
with the BBC’s first use of a High
Definition channel in 2006, ITV
and many Sky channels soon
followed suit in 2007. High
Definition Televisions and
Channels have proved so
popular because it allows the
viewers to watch programming
with high quality picture
resolution. HD Televisions are in
high demand today and sell
extremely fast because of the
steadily growing availability of
HD technology.

Internet Streaming is also fairly recent,
but is slowly overtaking conventional
Television due to its increasing
availability and efficiency. Websites
such as LOVEFILM.com and NetFlix
offer deals where, for a certain amount
of money a month, the viewer can
watch their favorite shows online and
on-demand, even allowing the viewing
of shows that may not be shown on
conventional Television anymore. The
problem with such readily available
Programming online lies with Piracy.
Piracy is very easy over the Internet
and it costs the TV business money.
Instead of paying to see a newly
released film, anyone can go online
and find a free pirated version to
watch, which means that film
companies lose out on potential profits
for their work.

On Demand allows the viewer to watch
Television Programing when ever they
want. Websites such as 4OD, BBC
Iplayer and even Youtube.com host On
Demand services for viewers to watch
whatever they want.
Pay-per-View is rather self
explanatory, for a one time payment,
you can view a show. Pay-per-View is
often used for Sporting events such as
Boxing, where you can pay to view a
single match. Sky Box Office offer a
Pay-per-View service, in which you
pay to view a film. Digital Recording is
also a useful service offered by Sky,
allowing you to record a program or a
series of programs for later viewing,
allowing the viewer to watch the
recorded program as many times as
the viewer wants.
Film
-Bas
ed
Before 1990, a Television Show
would be shot using film and
video. Film was easier to edit
compared to video, involving
physically cutting the film into
pieces and sticking them together.
Video on the other hand can be
‘Vision Mixed’ to create cuts, and
can be edited digitally, allowing for
more precise editing. With Digital
Editing allowing for more efficient,
faster and easier editing, film
became obsolete. Digital Editing
allowed reality shows such as Big
Brother to thrive, because footage
could now be easily found and
quickly edited together, with good
results.
