Parental Control
A function of the DVD VIDEO to limit
playback of the disc by the age of the
users according to the limitation level in
each country. The limitation varies from
disc to disc; when it is activated, playback
is completely prohibited, violent scenes
are skipped or replaced with other scenes
and so on.
Playback Control (PBC)
Signals encoded on VIDEO CDs (Version
2.0) to control playback. By using menu
screens recorded on VIDEO CDs with
PBC functions, you can enjoy playing
simple interactive programs, programs
with search functions, and so on.
Progressive format (sequential
scanning)
In contrast to the Interlace format, the
progressive format can reproduce 50 – 60
frames per second by reproducing all
scanning lines (525 lines for the NTSC
system, 625 lines for PAL system). The
overall picture quality increases and still
images, text and horizontal lines appear
sharper.
Region Code
This system is used to protect copyrights.
A region code is allocated on each DVD
system or DVD VIDEO according to the
sales region. Each region code is shown
on the unit as well as on the disc
packaging. The system can play back the
discs that match its region code. The
system can also play back discs with the
“
” mark. Even when the region code is
not shown on the DVD VIDEO, the
region limit may still be activated.
VIDEO CD
A compact disc that contains moving
pictures.
The picture data uses the MPEG 1 format,
one of the worldwide standards for digital
compression technology. The picture data
is compressed to about 1/140 of its
original size. Consequently, a 12 cm
VIDEO CD can contain up to 74 minutes
of moving pictures.
VIDEO CDs also contain compact audio
data.
Sound outside the range of human hearing
are compressed while the sounds we can
hear are not compressed. VIDEO CDs can
hold 6 times the audio information of
conventional AUDIO CDs.
There are 2 versions of VIDEO CDs.
• Version 1.1: You can play back only
moving pictures and sounds.
• Version 2.0: You can play back high-
resolution still pictures and enjoy PBC
functions.
This system conforms to both versions.
