About Digital Audio Broadcasting (DAB)
DAB digital radio is a new way of broadcasting radio via a network of terrestrial
transmitters. It provides listeners with more choice and information delivered in crystal
clear, crackle-free sound quality.
– The technology allows the receiver to lock on to the strongest signal it can find.
– With DAB digital stations there are no frequencies to remember, and sets are tuned
by station name, so there's no retuning on the move.
What is a multiplex?
Digital radio operation is made up of a single block of frequencies called a multiplex.
Each multiplex works within a frequency spectrum, such as Band III for DAB broadcasts.
Helpful Hints:
– If you buy a receiver in the UK it will be designed to pick up DAB signals on Band III
only. You will receive only those stations within your transmission area.
DAB BROADCASTERS AND DLS
Each DAB broadcaster (or multiplex operator) also provides text and audio data services.
Some programmes are supported by Dynamic Label Segments (DLS). This is data which
you can read as scrolling text on your DAB radio display. Some stations transmit the
latest news, travel, and weather, what's on now and next, website addresses and
phone numbers.
