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.
