artist’s name, the album title, the music genre,
the year of production, comments and other
data. The contents can be freely edited using
software with ID3 tag editing functions.
Although the tags are restricted by the
number of characters, the information can be
viewed when the track is played back.
ISO 9660 format
This is the international standard for the
format logic of DVD/CD-ROM folders and
files. For the ISO9660 format, there are
regulations for the following two levels:
• Level 1:
The file name is in 8.3 format (the name
consists of up to eight characters, half-byte
English capital letters, half-byte numerals
and the “_” sign, with a file-extension of
three characters).
• Level 2:
The file name can have up to 31 characters
(including the separation mark “.” and a file
extension). Each folder contains less than
eight hierarchies.
JPEG
This stands for Joint Photographic Experts
Group, and is an international still image
compression standard.
MP3
MP3 is short for MPEG Audio Layer 3. It is an
audio compression standard established by a
working group (MPEG) of the ISO
(International Organization for
Standardization). MP3 is able to compress
audio data to about 1/10th the size of a
conventional disc.
MPEG
This stands for Moving Pictures Experts
Group, and is an international video image
compression standard.
Multi-session
Multi-session is a recording method that
allows additional data to be recorded later.
When recording data on a CD-ROM, CD-R or
CD-RW, etc., all data from beginning to end is
treated as a single unit or session. Multi-
session is a method of recording more than
two sessions in one disc.
Packet write
This is a general term for a method of writing
individual files to a CD-R, etc. whenever
required, just as is done with files on floppy or
hard disks.
Phone book
An address book on user’s phone is
collectively referred to as “Phone book”.
Depending on the mobile phone, the phone
book may be called a name such as
“Contacts”, “Business card” or something
else.
Point Of Interest (POI)
Any of a range of locations stored in the data,
such as railway stations, shops, restaurants,
and amusement parks.
Route setting
The process of determining the ideal route to
a specific location; route setting is done
automatically by the system when you specify
a destination.
Set route
The route marked out by the system to your
destination. It is highlighted in bright colour on
the map.
Track log
Your navigation system logs routes that you
already passed through if the track logger is
activated. This recorded route is called a
“track log”. It is handy when you want to check
a route travelled or if returning along a
complex route.
VBR
VBR is short for variable bit rate. Generally
speaking, CBR (constant bit rate) is more
widely used. But by flexibly adjusting the bit
rate according to the needs of audio
compression, it is possible to produce
compression-priority data.
Voice guidance
The giving of directions by navigation voice
while in guidance.
Waypoint
A location that you choose to visit before your
destination; a journey can be built up from
multiple waypoints and the destination.
