Definition of terms
Digital audio output connector
(Optical)
[ Interactive DVD
The digital audio output connector (opti­
cal) converts electrical signals into optical
signals and transfers them to the amplifi­
er. Consequently, it has a number of fea­
tures including its immunity from electrical
interference from external sources and its
ability to prevent the generation of noise
and its minimal effect on the external envi­
ronment.
[ Dolby Digital (AC-3)
Dolby Digital (AC-3) is a digital sound
compression technique developed by the
Dolby Laboratories Licensing
Corporation.
Supporting 5.1-channel surround sound,
as well as stereo (2-channel) sound, this
technique enables a large quantity of
sound data to be efficiently recorded on a
disc.
[ Dolby Pro Logic Surround decoder ]
This is a unit which uses the Dolby
Surround (Pro Logic) system to restore 4-
channel signals which were recorded on
2 channels back to the signals of 4 sepa­
rate channels during playback. Compared
with Dolby Digital (AC-3) / 5.1 channel
surround sound, the channel separation is
not as good and surround signals can be
reproduced only up to a frequency of
7 kHz.
An interactive DVD is DVD software which
includes multiple angles, multiple plot
endings, etc.
[ Letterbox screerT
This refers to a screen on which the play­
back picture of wide-screen DVDs or
Video CDs appears with black bands run­
ning along the top and bottom.
Linear PCM audio (LPCM)
This refers to a signal recording format
used in CDs.
While CDs are recorded in 44.1 kHz/
16 bit, DVDs are recorded in 48 kHz/16 bit
up to 96 kHz/24 bit, thus achieving higher
quality audio than that of CDs.
MPEG
(Moving Picture Experts Group)
MPEG is an international standard format
for the compression of motion video as
defined by the Moving Picture Experts
Group, a working committee which func­
tions
under the auspices of the
International Standardization Organization
and International Electrotechnical
Commission. The Group established the
MPEG 1 standard in 1991 and the MPEG
2 standard in 1994. MPEG 2 builds on
MPEG 1 with many improvements, and it
yields a higher picture quality level.
Pan & Scan screen )
This refers to a screen on which the play­
back picture of wide-screen DVDs or
Video CDs is cut off at the left and right
sides.
