ISO9660format
Thisis the international standard for the for-
matlogic of CD-ROM folders and files. For the
ISO9660format, there are regulations for the
followingtwo levels.
Level1:
Thefile name is in 8.3 format (the name con-
sistsof up to 8 characters, half-byte English
capitalletters and half-byte numerals and the
“_”sign,with a file-extension of three charac-
ters).
Level2:
Thefile name can have up to 31 characters (in-
cludingthe separation mark “.”and a file ex-
tension).Each folder contains less than 8
hierarchies.
Extendedformats
Joliet:
Filenames can have up to 64 characters.
Romeo:
Filenames can have up to 128 characters.
JPEG
Thisstands for Joint Photographic Experts
Group,and is an international still image com-
pressionstandard.
LinearPCM (LPCM)/Pulse code
modulation
Thisstands for linear pulse code modulation,
whichis the signal recording system used for
musicCDs and DVDs. Generally, DVDs are re-
cordedwith higher sampling frequency and
bitrate than CDs. Therefore, DVDs can provide
highersound quality.
m3u
Playlistscreated using the “WINAMP”sof t-
warehave a playlist file extension (.m3u).
MP3
MP3is short for MPEG Audio Layer 3. It is an
audiocompression standard set by a working
group(MPEG) of the ISO (International Stan-
dardsOrganization). MP3 is able to compress
audiodata to about 1/10th the level of a con-
ventionaldisc.
MPEG
Thisstands for Moving Pictures Experts
Group,and is an international video image
compressionstandard. Some DVDs feature di-
gitalaudio compressed and recorded using
thissystem.
MSADPCM
Thisstands for Microsoft adaptive differential
pulsecode modulation, which is the signal re-
cordingsystem used for the multimedia soft-
wareof Microsoft Corporation.
Multi-angle
Withregular TV programs, although multiple
camerasare used to simultaneously shoot
scenes,only images from one camera at a
timeare transmitted to your TV. Some DVDs
featurescenes shot from multiple angles, let-
tingyou choose your viewing angle as desired.
Multi-audio(Multilingual dialog)
SomeDVDs feature dialog recorded in multi-
plelanguages. Dialog in up to 8 languages
canbe recorded on a single disc, letting you
chooseas desired.
Multi-session
Multi-sessionis a recording method that al-
lowsadditional data to be recorded later.
Whenrecording data on a CD-ROM, CD-R or
CD-RW,etc., all data from beginning to end is
treatedas a single unit or session. Multi-ses-
sionis a method of recording more than 2 ses-
sionson one disc.
Multi-subtitle
Subtitlesin up to 32 languages can be re-
cordedon a single DVD, letting you choose as
desired.
Numberof quantization bits
Thenumber of quantization bits is one factor
inthe overall sound quality; the higher the
“bit-depth”,the better the sound quality. How-
ever,increasing the bit-depth also increases
theamount of data and therefore storage
spacerequired.
