Multi-angle
With regular TV programmes, although multi-
ple 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 dialogue)
Some videos feature dialogue recorded in mul-
tiple languages or audio recorded in multiple
tracks. For example, dialogue in up to eight
languages can be recorded on a single
DVD-Video, letting you choose the language
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 two
sessions in one disc.
Multi-subtitle
For example, subtitles in up to 32 languages
can be recorded on a single DVD-Video, letting
you choose as desired.
Packet write
This is a general term for a method of writing
individual files to a CD-R, etc. whenever re-
quired, just as is done with files on floppy or
hard disks.
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.

’
s phone is collec-
tively referred to as

or something else.
