Multilingual function
Several languages for the sound or subtitles in a
picture are recorded on some DVDs.
Parental Control
A function of the DVD 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 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.
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.
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.
Scene
On a VIDEO CD with PBC (playback control)
functions, the menu screens, moving pictures
and still pictures are divided into sections called
“scenes.”
Super Audio CD
Super Audio CD is a new high-quality audio
disc standard where music is recorded in the
DSD (Direct Stream Digital) format
(conventional CDs are recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency
range, and so provides music reproduction
extremely faithful to the original sound.
