x Music mode
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround,
Dolby Surround Pro Logic produces four
channels from 2 channel sound. Compared with
the former Dolby Surround system, Dolby
Surround Pro Logic reproduces left-to-right
panning more naturally and localizes sounds
more precisely. To take full advantage of Dolby
Surround Pro Logic, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. This format
comprises of stereo rear channel and there is
discrete subwoofer channel in this format. DTS
provides the same 5.1 discrete channels of high
quality digital audio. The good channel
separation is realized due to the all channel data
being recorded discretely and processed in
digitally.
HDMI (High-Definition Multimedia
Interface)
HDMI is an interface that supports both video
and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Content Protection), a copy protection
technology that incorporates coding technology
for digital video signals.
Interlace format
(Interlaced scanning)
The Interlace format is the NTSC standard
method for displaying TV images at 30 frames
per second. Each frame is scanned twice -
alternately between the even numbered scanning
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 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.
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.
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.
x 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
