The IBOC system is referred to as a "hybrid"
since it is both analog and digital. During
hybrid operation, receivers still continue to
receive the analog (non-digital) signal. HD
Radio receivers incorporate both modes of
reception, where the receiver will automati-
cally switch to the analog signal if the digital
signal cannot be decoded or is lost by the
receiver.
When you have tuned to an HD Radio station,
the symbol will appear in the infotain-
ment system display. The symbol will be dis-
played in different colors:
Grayed-out symbol: no HD Radio broad-
•
cast reception
White symbol: the radio is actively receiv-
•
ing an HD broadcast
Orange symbol: the radio is receiving an
•
HD broadcast with digital sound

Artist Experience™
A radio station's logo and album art can be
displayed. If a station opts to provide this
information, it is broadcast once every 12
minutes, which means that there may be a
delay before the logo/album art appear on the
screen. The radio can store 100 station logos
so the next time the radio is tuned to the same
station, the logo will be displayed immedi-
ately. Album art is synched with the artist that
you are currently listening to.
Ball game mode
This feature means that a main FM station
(HD1) will broadcast live events, where the
content of the programming is more important
than sound quality, in analog mode only to
help prevent the delay between analog and
digital broadcasting. The HD Radio symbol
will be white during live broadcasts and "Live"
will be displayed next to the symbol.
Benefits of digital broadcasting
Better sound (FM sounds near CD quality
•
and AM as analog FM).
Some FM frequencies offer a greater
•
number of listening choices through multi-
casting (consisting of a frequency's main
channel and any sub-channels that may
also be available on that particular fre-
quency.)
When receiving a digital signal there is no
•
multipath disturbance or hisses/pops/
crackling due to outside influences.
How HD Radio ™ Technology
broadcasting works
HD Radio works similarly to conventional
radio and broadcasts of this type are available
in many areas of the United States. However,
there are a few key differences:
AUDIO, MEDIA AND INTERNET
Instead of transmitting one analogue sig-
•
nal, stations send out a bundled signal –
both analog and digital.
An HD Radio receiver can receive both
•
digital and analog broadcasts. Depending
on the terrain and location of the vehicle
(which will influence the signal strength),
the receiver will determine which signal to
receive.
