lines and then odd numbered scanning lines, at
60 times per second.
Parental Control
A function of the DVD to limit playback of the
disc by the age of 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.
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). 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.
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.
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 CD is 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.

Super Audio CD types
There are two types of discs, depending on the
Super Audio CD layer and CD layer
combination.
• Super Audio CD layer: A high-density
signal layer for Super Audio CD
• CD layer
1)
: A layer that is readable by a
conventional CD player
A Super Audio CD layer consists of the 2
channel area or the multi-channel area.
• 2 channel area: An area in which 2 channel
stereo tracks are recorded
• Multi-channel area: An area in which multi-
channel (up to 5.1 channels) tracks are
recorded
1)
You can play the CD layer on a conventional CD
player.
2)
Since both layers are on one side, it is not necessary
to turn the disc over.
3)
To select a layer, see “Changing a playback layer for
a hybrid Super Audio CD” (page 32).
