Explanation
of technical terms
The IV receiver in the radio navigation system is
equipped
with a
"hybrid
re-
ceiver" capable
of receiving both analogue and digital IV
stations via
the vehicle
aerial.
"Universal TV" or DVB_T
1S )
Analogue
TV stations
that
can
be
received every-
where
by domestic aerials
are
becoming less fre-
quent
as a
result of advances in digital
transmis-
sion
technology.
The
quality offered
is often
not
acceptable
today.
It
has
still
been used
for
in-car
applications,
however,
as
digital
TV
reception
relied
on
a
fixed
cable
connection
(DVB-CJ or a
directional
satellite
dish (OVB-SJ.
In
DVB-T,
digital TV signals
are
transmitted
ter-
res
triallyl9)
and can
be received by an
aerial.
DVB-T provides high quality mobile reception
without the need
for a fIXed
aerial connection.
DVB-T
is also known as "universal TV"
.
The advantages of DVB-T
Digital television offers
conSiderably higher
quality
than
analogue
television.
Digital
trans-
mission tech.nology is also
far
better
able
to uti
-
lise
the transmission
capacity of a
television sta-
tion than
analogue signals. Digital
terrestrial
broadcasting
provides many more
channels
than
analogue broadcasting as
signals
can
be
combined
in
a single
stream
("multiplex:ing"J.
The
transmission capacity
can also
be used
for
additional services such as electronic
TV
guides
20)
and radio
broadcasts.
"Hybrid receiver" for analogue and digital re-
ception
DVB-T
is
currently
not
available
in
all
areas,
and
the unit
in
the
veh.icle still
relies
on an
analogue
TV
receiver.
For
this reason,
a
hybrid
receive~1)
has been developed for the unit,
co
nsisting of
a
conventional analogue
TV receiver
and a DVB-T
receiver.

Availability of DVB-T and functional description
of the "hybrid receiver"
In areas
where
DVB-T
is available, analogue
TV
is gradually being phased
out.
This
means that
in
some areas only
digital
or only analogue TV
may be
available.
In
some areas
both
analogue
and
digital
TV are available.
In
areas
that do not have
DVB-T, only analogue
TV is
available with
the
corresponding
restric-
tions.
Display of analogue and digital TV stations
The
TV station
that
is
being
received
is
shown
in
the display
of
the
co
mbi -instrument
and
also
on
the screen
of
th
e
radio
navigation
sys
tem
when
you change over and activate the TV
menu.
Ana-
logue
and
digital
TV stations are
shown in dif-
ferent
ways and are
identified
on
the screen
by
"Anologue" or
"OVB-T"
