2011 INFINITI G-CONVERTIBLE audio

Compressed Audio Files (MP3/WMA/
AAC)
Explanation of terms :
●MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well known compressed digital audio
file format. This format allows for near “CD
quality” sound, but at a fraction of the size
of normal audio files. MP3 conversion of an
audio track can reduce the file size by
approximately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually no
perceptible loss in quality. The compression
reduces certain parts of sound that seem
inaudible to most people.
● WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft as an alternative to MP3. The WMA
codec offers greater file compression than
the MP3 codec, enabling storage of more
digital audio tracks in the same amount of
space when compared to MP3s at the same
level of quality.
● AAC/M4A — Advanced Audio Coding (AAC) is
a lossy audio compression format. Audio
files that have been encoded with AAC are
generally smaller in size and deliver a higher
quality of sound than MP3. ●
Bit rate — Bit rate denotes the number of
bits per second used by a digital music file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file.
● Sampling frequency — Sampling frequency
is the rate at which the samples of a signal
are converted from analog to digital (A/D
conversion) per second.
● Multisession — Multisession is one of the
methods for writing data to media. Writing
data once to the media is called a single
session, and writing more than once is
called a multisession.
● ID3/WMA Tag — The ID3/WMA tag is the part
of the encoded MP3 or WMA file that con-
tains information about the digital music file
such as song title, artist, album title, encod-
ing bit rate, track time duration, etc. ID3 tag
information is displayed on the
Album/Artist/Track title line on the display.

●If there is a file in the top level of a disc/USB,
“Root Folder” is displayed.
● The playback order is the order in which the
files were written by the writing software, so
the files might not play in the desired order.
● Music playback order of compressed audio
files is as illustrated in the next figure.

Troubleshooting guide:
SymptomCause and Countermeasure
Cannot play Check if the disc or USB device was inserted correctly.
Check if the disc is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) be-
fore using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal temperature.
If there is a mixture of music CD files (CD-DA data) and compressed audio files on a CD, only the music CD files (CD-DA
data) will be played.
Files with extensions other than “.MP3 (.mp3)”, “.WMA (.wma)”, “.AAC (.aac)”, “.M4A (.m4a)”, or “.AA3 (.aa3)” cannot
be played. In addition, the character codes and number of characters for folder names and file names should be in
compliance with the specifications.
Check if the disc or the file is generated in an irregular format. This may occur depending on the variation or the set-
ting of compressed audio writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the disc or USB device is protected by copyright.
Poor sound quality Check if the disc is scratched or dirty.
It takes a relatively long time
before the music starts playing. If there are many folder or file levels on the disc or USB device, some time may be required before the music starts
playing.
Music cuts off or skips The writing software and hardware combination might not match, or the writing speed, writing depth, writing width,
etc., might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next
song when playing. If an unsupported compressed audio file has been given a supported extension like .MP3, or when play is prohibited
by copyright protection, the player will skip to the next song.

SymptomCause and Countermeasure
The songs do not play back in
the desired order. The playback order is the order in which the files were written by the writing software, so the files might not play in
the desired order.
Random/Shuffle may be active on the audio system or on a USB device.

Compressed Video Files (models with
navigation system)
Explanation of terms :
●DivX - DivX refers to the DivX codec
owned by DivX, Inc. used for a lossy com-
pression of video based on MPEG-4.
● AVI - AVI stands for Audio Video Interleave. It
is a standard file format originated by Micro-
soft Corporation. A “.divx” encoded file can
be saved into the “.avi” file format for play-
back on this system if it meets the require-
ments stated in the table in this section.
However, not all the “.avi” files are playable
on this system since different encodings can
be used than the DivX codec.
● ASF - ASF stands for Advanced Systems
Format. It is a file format owned by Microsoft
Corporation. Note: Only “.asf” files that meet
the requirements stated in the table in this
section can be played.
● Bit rate — Bit rate denotes the number of
bits per second used by a digital video file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file.

BluetoothAudio player (models with
navigation system)
● Some Bluetooth audio devices may not be
recognized by the in-vehicle audio system.
● It is necessary to set up the wireless con-
nection between a compatible Bluetooth
audio device and the in-vehicle Bluetooth
module before using the Bluetooth audio
player.
● Operating procedure of the Bluetooth au-
dio player will vary depending on the device.
Make sure it is understood how to operate
an audio device before using it with this
system.
● The Bluetooth audio player may be stopped
under the following conditions:
– Receiving a hands-free call.
– Checking the connection to the hands- free phone.
● Do not place a Bluetooth audio device in an
area surrounded by metal or far away from
the in-vehicle Bluetooth module to prevent
tone quality degradation and wireless con-
nection disruption.
