DAB
Overview of DAB
DAB (Digital Audio Broadcasting) is a new
multimedia broadcasting system that transmits
audio programmes with a quality comparable
to that of CDs. This is made possible by the use
of a microcomputer in the DAB tuner which
uses the radio signals sent from multiple
aerials and multi-path signals (reflected radio
waves) to boost the strength of the main signal.
This makes DAB almost immune to radio
interference even in a moving object such as a
car.
Each DAB station bundles radio programmes
(services) into an ensemble which it then
broadcasts. Each service contains one or more
components. All ensembles, services, and
components are identified by name, so you can
access any of them without having to know
their frequencies.
DAB programme
Notes
• The DAB system is actually in a testing phase.
This means some services have not been
sufficiently defined or are presently being tested.
At present, such services are not supported by
the optional DAB tuner unit XT-100DAB.
• DAB programmes are broadcast in Band-III (174
to 240 MHz) and L-Band (1,452 to 1,492 MHz),
with each band divided into channels (41 in
Band-III and 23 in L-Band). One ensemble is
broadcast per channel by each DAB station.
• When you change the mode from FM3 to DAB,
all the AF TA modes stay active.
• When you change any of the AF TA modes in
DAB, that mode stays active in FM1.
