With this unit you can receive and listen to Digital
Audio Broadcast (DAB) programmes. DAB uses digital,
not analogue signals, resulting in near CD-quality
audio with virtually interference-free reception. Along
with superior quality audio, DAB can also deliver
additional audio channels and text. In the future,
computer data and images are also possible.
Digital radio is broadcast as groups of data called
ensembles or multiplexes. Each multiplex can contain a
number of stations (services) and each station contains
a primary service and can contain secondary services
as illustrated in the following diagram.
Each multiplex is transmitted in a set frequency range
and received by this unit for decoding. You can receive
multiplexes broadcast in the 174-240 MHz frequency
band and store the services in each multiplex for you
to access. The number of multiplexes you receive
depend on your location. Channels used in the UK are
in the range 10A to 12D.
Multiplexes and stations have labels (names) that are
used to identify them. Instead of needing to know the
particular frequency of your favourite broadcast, you
can simply select the station name. Secondary services
and additional data such as text or multiplex info are
also available.
