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 level 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, CD-R or
CD-RW, etc., all data from beginning to end is
treated as a single unit or session. Multi-ses-
sion is a method of recording more than 2 ses-
sions 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/input
By transmitting and receiving audio signals in
a digital signal format, the chance of sonic
quality deteriorating in the course of transmis-
sion is minimized. An optical digital output/
input is designed to transmit and receive digi-
tal 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.
