lnteresting facts about RDS (Radio Data System)
RDS is a system
fortransmitting auxiliary information (data) via
a
radio transmit
ter. The
introduction of
RDS
will
considerably enhance the services offered by
FM radio.
A subcarrier modulated with
a
data channel
is
broadcast bythe radio
transmitter together
with the conventional stereo signal and can be processed
by tuners that are equipped
for
receiving such signals.
S
uch data increase the operati ng conveni ence
of
the
I
isteners
a
nd offer
a
wealth
of useful supplementary information.
During the introductory
phase the
following
RDS
services
will
be offered:
a
Program name
The program
name
comprising
up
to eight characters wlll
be
transmit
ted over the data channel (Example:
DRS1. BRF3, BBC1,
SWF2).
a
Alternate frequencies
lf an FM program can be received on multiple frequencies, these so-
called alternate frequencies
are
transmitted over the data channel.
a
ARI
replacement
D
uring
the introductory phase of ten years,
RDS
will eventually replace
the
ARI system
which
supplies
information to motorists.
During this
changeover
period,
receivers equipped for
RDS
can already be
used
while
those equipped
for
ARI can be operated as
usual.
ldentification
of
transmitters
that
broadcast
traffic
information
and
their
announcements is possible as has been the case
with
ARl.
The
following examples are planned enhancements to
the radio data systerns
which
are
to
be implemented after the introductory phase.
The scope of these enhancements
will
depend on the radio transmitters and on
the equipment manufacturers.
O Program
type
After
the
introduction
of
satellite
rad io, the transm itters
will
be
assigned
a
uniform
type of program identification
(P-TYPE) such as
DRS3,
SWF3, BR4, ORF3.
Examples are given under the Section "P-TYPE".
I
Voice and music
Frequently,
a
difference
in
thevolume
between music
and
voice
is
desi-
red. ln the future it may
be
possible to
controlthe volume by means of
the
RDS data channel.
O Text display
One of the refinements planned for
RDS foresees
the possibility
of
broadcasting
any
texts
(e.
g.
program changes of
a station)
which
can
be made visible on the
64 position
display
of future tuners.
O
Time signal
Broadcasting
of
control signals
that
permit
synchronization
of
local
clocks with
a ref
erence clock. This means local clocks could
be
control
led by the
tuner.
However, these enhancements
are only available
if
the radio transmitters and the
receivers are correspondingly equipped.
Conventional tuners cannot
use
the
RDS information.
Your
RFVOX
8260-5
Tuner is
already prepared
for operation with RDS. When
the
RDS
system goes on the
air,
your tuner
can
be
easily upgraded by
retrofitting
the corresponding
RDS option.
P{YPE
To
permit logical grouping
by
program types,
a
standard
has been
agreed upon
in
Europe.
This means that all prograrns of
a
given type that can be received
in
Europe either
directly
or via satellite can be accessed by the same P-Type.
