The sampling frequency, number of bits and number of channels used for recording of music, etc., in studios has been increasing _nrecent years, and there are a growing number of high quality signal sources, including 96 kHz/24 bit 5.1-channel sources. For example, there are high picture/sound quality DVD video sources with 96 kHz/24 bit stereo PCM audio tracks. However, because the data rate for these audio tracks is extremely high, there are limits to recording them on two channels only, and since the quality of the pictures must be restricted it is common to only include still pictures. In addition, 96 kHz/24 bit 5.1-channel surround is possible with DVD audio sources, but DVD audio players are required to play them with this high quality. DTS 96/24 is a multi-channel digital signal format developed by Digital Theater Systems inc. in order to deal with this situation. Conventional surround formats used sampling frequencies of 48 or 44.1 kHz, so 20 kHz was about the maximum playback signal frequency. DTS 96/24, the sampling frequency is increased to 96 or 88.2 kHz to achieve a wide frequency range of over 40 kHz. In addition, DTS 96/24 has a resolution of 24 bits, resulting in the same frequency band and dynamic range as 96 kHz/24 bit PCM. With As with conventional DTS Surround, DTS 96/24 is compatible with a maximum of 5.1 channels, so sources recorded using DTS 96/24 can be played in high sampling frequency, multiple channel audio with such normal media as DVD videos and CDs. Thus, with DTS 96/24, the same 96 kHz/24 bit multi-channel surround sound as with DVD-Audio can be achieved while viewing DVD-Video images on a conventional DVD-Video player (_ 1). Furthermore, with DTS 96/24 compatible CDs, 88.2 kHz/24 bit multi-channel surround can be achieved using normal CD/LD players (_ 1). Even with the high quality multi-channel signals, the recording time is the same as with conventional DTS surround sources. What's more, DTS 96/24 is fully compatible with the conventional DTS surround format, so DTS 96/24 signal sources can be played with a sampling frequency of 48 kHz or 44.1 kHz on conventional DTS or DTS-ES surround decoders ( _ 2). ,_ 1 : A DVD player with DTS digital output capabilities (for CD/LD players, a player with digital outputs for conventional DTS CDs/LDs) and a disc recorded in DTS 96/24 are required. _2: The resolution is 24 or 20 bits, depending on the decoder. 71

The sampling
frequency,
number
of bits and number
of channels
used for recording
of music, etc., in studios
has been
increasing
_nrecent
years,
and there are a growing
number
of high quality
signal sources,
including
96 kHz/24
bit 5.1-channel
sources.
For example,
there are high picture/sound
quality DVD video sources
with
96 kHz/24 bit stereo
PCM audio tracks.
However,
because
the data rate for these
audio tracks
is extremely
high, there are limits
to recording
them
on two
channels
only, and since the
quality
of the pictures
must be restricted
it is common
to only
include still pictures.
In addition,
96 kHz/24 bit 5.1-channel
surround
is possible
with
DVD audio sources,
but DVD audio players are required
to play them
with this high
quality.
DTS 96/24
is a multi-channel
digital signal format
developed
by Digital Theater
Systems
inc. in order to deal with
this situation.
Conventional
surround
formats
used sampling
frequencies
of 48 or 44.1 kHz, so 20 kHz was about the maximum
playback
signal frequency.
With
DTS 96/24,
the sampling
frequency
is increased
to 96 or 88.2
kHz to achieve a wide frequency
range of over 40 kHz.
In addition,
DTS 96/24 has a resolution
of 24 bits,
resulting
in the same frequency
band and dynamic
range as 96 kHz/24
bit PCM.
As with
conventional
DTS Surround,
DTS 96/24
is compatible
with
a maximum
of 5.1 channels,
so sources
recorded
using
DTS 96/24
can be
played in high sampling
frequency,
multiple
channel audio with
such normal
media as DVD videos
and CDs.
Thus, with
DTS 96/24, the same 96 kHz/24
bit multi-channel
surround
sound as with
DVD-Audio
can be achieved while
viewing
DVD-Video
images
on a conventional
DVD-Video
player (_ 1). Furthermore,
with
DTS 96/24 compatible
CDs, 88.2 kHz/24 bit multi-channel
surround
can be achieved
using normal
CD/LD players
(_ 1).
Even with the
high quality
multi-channel
signals,
the recording
time is the same as with
conventional
DTS surround
sources.
What's
more,
DTS 96/24
is fully
compatible
with
the
conventional
DTS surround
format,
so DTS 96/24
signal
sources
can be played
with
a
sampling
frequency
of 48 kHz or 44.1 kHz on conventional
DTS or DTS-ES surround
decoders
( _ 2).
,_ 1 : A DVD player with
DTS digital output
capabilities
(for CD/LD players,
a player with
digital
outputs
for conventional
DTS CDs/LDs)
and a
disc recorded
in DTS 96/24
are required.
_2:
The resolution
is 24 or 20 bits,
depending
on the decoder.
