playback is completely prohibited, violent 
scenes are skipped or replaced with other scenes 
and so on.

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.

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 the 
PAL system). The overall picture quality 
increases and still images, text and horizontal 
lines appear sharper. This format is compatible 
with the 525 or 625 progressive format.

This system is used to protect copyrights. A 
region number is allocated on each DVD system 
or DVD disc according to the sales region. Each 
region code is shown on the system as well as on 
the disc packaging. The system can play discs 
that match its region code. The system can also 
play discs with the “

” mark. Even when the 

region code is not shown on the DVD, the region 
limit may still apply.

On a VIDEO CD with PBC (playback control) 
functions, the menu screens, moving pictures 
and still pictures are divided into sections called 
“scenes.”

The longest section of a picture or music feature 
on a DVD, movie, etc., in video software, or the 
entire album in audio software. 

Section of a picture or a music piece on a 
VIDEO CD, CD, or MP3. An album is 
composed of several tracks (MP3 only). 

A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of 
a worldwide standard of 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. 
Sounds outside the range of human hearing are 
compressed while 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 only moving 

pictures and sounds.

• Version 2.0: You can play high-resolution still 

pictures and enjoy PBC functions.

This system conforms to both versions.
