DAB - What is it?
DAB is short for 'Digital Audio Broadcasting', and it will
completely change the way we listen to radio again.
With traditional analogue signals (such as AM & FM), you are
prone to interference and break up in the transmissions, whereas
with DAB you get more robust and clear reception in CD like
quality, without an hiss or crackling noises.
Also with DAB, there's no more need to tune into your stations,
at the touch of a button you can tune into your favourite
stations, listed within your DAB set, and instantly you are
connected!
How Does DAB Technology Work?
DAB radio works by using MPEG and COFDM technology which
converts the music or speech from analogue signal into digital
code. This vastly reduces the potential for the broadcast to be
corrupted during transmission by weather conditions, and other
problems that can degrade the quality of reception.
Interference which disturbs analogue signals (bouncing off
obstacles etc) is eliminated with DAB. DAB sets have processors
which correct the signal errors providing a better reception
overall.
All DAB Radio's have LCD screens allowing the radio station(s)
to broadcast information and messages for the listener, as well
as displaying current artist names and song titles. In the
future, it is believed DAB players will be able to record your
favorite shows, and be able to receive much more sophisticated
data.
DAB Offers More Choice
DAB is a much more efficient way to broadcast, meaning that
there's room for many more stations, both local and national.
In the UK there are currently just over 160 different DAB
digital radio stations being broadcast. There are stations for
people who like sport, talk radio, comedy, dance music, rock,
hip-hop, classical, alternative, world music, garage, jazz, big
band, pop, country, soul, disco, oldies and R&B. With digital
radio, there's something for everyone.
How Can I Receive DAB?
To receive DAB, you will need a DAB compatible aerial for either
your premises or your vehicle, and further to that a DAB
compatible player. Once these are installed correctly using the
required equipment, you should receive crystal clear audio.
Please note, DAB is currently available to approximately 85% of
the UK.
