JPEG
This stands for Joint Photographic Experts
Group, and is an international still image com-
pression standard.
Linear PCM (LPCM)/Pulse code
modulation
This stands for linear pulse code modulation,
which is the signal recording system used for
music CDs and DVDs. Generally, DVDs are re-
corded with higher sampling frequency and
bit rate than CDs. Therefore, DVDs can provide
higher sound quality.
m3u
Playlists created using the
“
WINAMP
”
soft-
ware have a playlist file extension (.m3u).
MP3
MP3 is short for MPEG Audio Layer 3. It is an
audio compression standard set by a working
group (MPEG) of the ISO (International Stan-
dards Organization). MP3 is able to compress
audio data to about 1/10th the size of a con-
ventional disc.
MPEG
This stands for Moving Pictures Experts
Group, and is an international video image
compression standard. Some DVDs feature di-
gital audio compressed and recorded using
this system.
Multi-angle
With regular TV programs, although multiple
cameras are used to simultaneously shoot
scenes, only images from one camera at a
time are transmitted to your TV. Some DVDs
feature scenes shot from multiple angles, let-
ting you choose your viewing angle as desired.
Multi-audio (Multilingual dialog)
Some DVDs feature dialog recorded in multi-
ple languages. Dialog in up to 8 languages
can be recorded on a single disc, letting you
choose as desired.
Multi-session
Multi-session is a recording method that al-
lows additional data to be recorded later.
When recording data on a CD-ROM, etc., all
data from beginning to end is treated as a sin-
gle unit or session. Multi-session is a method
of recording more than 2 sessions on one
disc.
Multi-subtitle
Subtitles in up to 32 languages can be re-
corded on a single DVD, letting you choose as
desired.
Optical digital output
By transmitting audio signals in a digital sig-
nal format, the chance of sonic quality dete-
riorating in the course of transmission is
minimized. An optical digital output is de-
signed to transmit digital signals optically.
Packet write
This is a general term for a method of writing
on CD-R, etc. at the time required for a file,
just as is done with files on floppy or hard
discs.
Parental lock
Some DVD-Video discs with violent or adult-or-
iented scenes feature parental lock which pre-
vents children from viewing such scenes. With
this kind of disc, if you set the unit
’
s parental
lock level, playback of scenes inappropriate for
children will be disabled, or these scenes will
be skipped.
Point of Interest (POI)
Point Of Interest; any of a range of locations
stored in the data, such as railway stations,
shops, restaurants, and amusement parks.
Region number
DVD players and DVD discs feature region
numbers indicating the area in which they
were purchased. Playback of a DVD is not pos-
sible unless it features the same region num-
