lines for the NTSC system). The overall picture 
quality increases and still images, text and 
horizontal lines appear sharper. This format is 
compatible with the 525 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.”

Sony’s long-term involvement in surround 
technology (and the vast amounts of acoustic 
data accumulated as a result) has led to the 
development of all-new processing method and 
advanced DSP to handle this task effectively, 
which we call S-Force PRO Front Surround. 
Compared with previous front surround 
technologies, S-Force PRO Front Surround 
reproduces a more convincing sense of distance 
and space, resulting in a true surround sound 
experience without the need for rear speakers.

S-Master is an all-digital amplifier technology 
developed by Sony, which effectively 
minimizes the occurrence of sound 
fragmentation and jitter, delivering superb 
dialog clarity and faithful reproduction of the 
original sound. The compact amplifier section 
supports a higher power efficiency and 
improved thermal performance.

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.
