audio
into 5.1ch for playback.
There
is a
MOVIE
mode for movies
and MUSIC
mode
for stereo sources
such as music.
Old movies
encoded
in the traditional
stereo format can be
enhanced
with 5. I ch surround
sound.
• Dolby Pro Logic IIx
Technology
for 7.lch
(or 6. lch) playback.
Along
with audio encoded
in Dolby Digital
Surround
EX, 5. I ch Dolby
Digital
encoded
audio can be reproduced
in 7. l ch (or 6. l ch).

content
can also be reproduced
in 7.1ch (or 6.1ch).
• Dolby Surround (Dolby Pro
Logic)
Audio
processing
technology
developed
by
Dolby
Laboratories,
Inc. Center and mono
surround
information
is matrixed
into two
stereo channels.
When reproduced,
audio is
decoded
and output in 4ch surround
sound.
This is the most common
audio
processing
method
for DVD-video.
• DTS 96/24
A high sound quality
digital signal format.
It
records
audio at a sampling
frequency
and bit
rate of 96kHz/24bit
which is the highest
possible
for DVD-video.
The nmnber
of
playback
channels
varies depending
on the
software.
• DTS Neo:6
This technology

and "Matrix
6.1" which matrixes
surround
back channel
into LS and RS channels.
It is
ideal for playback
of motion picture
soundtracks.
• Sampling frequency
To corn, err analog audio to digital,
analog data
should be quantified.
This process
is called
sampling,
and the number
of times per second
the analog data is quantified
is called the
sampling
frequency.
A standard
mnsic CD
stores data quantified
at 44,100
times per
second,
which is expressed
as a sampling
frequency
of 44.1 kHz. Generally
speaking,
a
higher sampling
frequency
means better sound
quality.
• S-VIDEO signal
A format for transmitting
video signal
information.
S-video
uses a single cable and
two channels,
one for the Lunfinance
signal Y
and another
for the chrominance
signal C.
Better picture
quality
for recording
and
playback
than that of composite
signal is
achieved.
