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.
Region Code
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.
Scene
On a VIDEO CD with PBC (playback control)
functions, the menu screens, moving pictures
and still pictures are divided into sections called
“scenes.”
S-Force PRO Front Surround
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
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.
Title
The longest section of a picture or music feature
on a DVD, movie, etc., in video software, or the
entire album in audio software.
Track
Section of a picture or a music piece on a
VIDEO CD, CD, or MP3. An album is
composed of several tracks (MP3 only).
VIDEO CD
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.
