7 DAB+ (digital radio) function

7.1 What is DAB+?

DAB+ is a new digital format through which crystal clear sound with no noise can
be heard. In contrast to conventional analogue radio stations, DAB+ can be used to
broadcast multiple stations on one and the same frequency. This is referred to as an
ensemble or multiplex. An ensemble is comprised of the radio station, as well as several
service components or data services, which are broadcast individually by the radio
stations. There is information at www.digitalradio.de or www.digitalradio.ch, for example.

7.1.1 Data compression

By doing so, digital radio takes advantage of the properties of human hearing. The
human ear does not perceive sounds which are found under a specific minimum
volume. Data which are found under the so-called audibility threshold can, therefore, be
filtered out.
