Digital
TV can be
received in four different ways, each with its own
features and suppliers. The service that you are able to receive may
depend on whereabouts you live.
Digital
Cable TV is supplied by either Telewest or NTL depending
on where you live in the country. You receive your digital TV through
cables in the ground via a set top box. Cable companies also offer a
host of competitive broadband and telephone packages alongside digital
TV. It will usually be cheaper to buy a package comprising all three
services than to obtain them individually from different service
providers. |

Satellite TV is supplied by Sky Digital. Digital signals
are sent and received by satellites meaning you need a mini-disc
attached to your property in order to receive digital satellite TV via
a digi-box. Sky Digital now offers free broadband to their customers.
Sky is well known to be the UK's main supplier of Premiership Football,
indeed having exclusive rights in recent years to show live Premier
League. Although this monopoly has now been broken, the vast majority
of top flight football is still with Sky. Their top packages include 4
dedicated in-house sports channels plus their extensive movie suite,
Sky Movies.
Normally, both cable and satellite television customers will have a
similar choice of channels, grouped into packages, such as sport,
films, news, music and education. It is therefore possible to tailor
your channels to your tastes and therefore save money compared to
ordering the full selection.
Cable
and Satellite viewers tend also to have access to
interactive services unlike terrestrial customers. This includes
enhanced sports coverage where viewers may select their camera angle,
or additional behind the scenes footage for their favourite soap opera
or drama. Cable customers subscribing to Telewest can choose to watch
selected television programmes on demand through the new Teleport
service, with includes many past series of comedy, drama and
documentaries, as well as programmes aired on the BBC over the past 7
days.
From a technical angle, both of these options (satellite and cable)
will require a technician to come to your home for installation,
although this is commonly carried out free of charge if you choose
carefully when to order.
Free to Air Digital TV is received via your existing TV aerial and
decoded using a set-top box or integrated digital TV. The most common
form is Freeview. Your ability to receive free to air digital TV
depends on where you live and the type of aerial you have. Existing
aerials can be upgraded in order to receive the service if necessary.
The Freeview service is a cut down version of Sky's digital satellite
selection, and Telewest and NTL's cable choices, and is primarily made
up of content supplied by the BBC (British Broadcasting Corporation).
At the time of writing, Freeview carries over 30 channels, covering
news, politics, terrestrial channels (in digital quality), comedy,
drama, films and sports news amongst others
Digital
ASDL TV is received via a high speed internet connection
through a standard telephone line. This service is strictly limited to
trial areas for the time being. It is widely anticipated that this will
become a commonplace method of viewing for a large section of the
population in the future.
