Brilliantly digital DVD
diversity
DVD-Audio: a new format is
born (DV-939A/DV-646A)
Multi-channel Surround Sound
For true music lovers, nothing equals
a live concert experience. Until now.
As well as the best-ever 2 channel
stereo, DVD-Audio delivers total-
immersion 6 channel surround sound
using a significantly higher definition
linear PCM (Pulse Code Modulation) ,
far exceeding the frequency range of
CDs. This fuller, more expressive
performance makes every sound
come alive.
Multi-channel sources play beauti-
fully also in 2 channel stereo – tracks
are automatically downmixed and the
DVD-Audio format even offers the
flexibility to the producer to steer
how this will be done by the player.
Advanced Information and
Interactive Capability
Just like DVD-Video, DVD-Audio discs
feature more than the performance.
In fact, your DVD-Audio disc can be
crammed full of artist bios,
background information, lyrics, liner
notes and more. If you want, you can
even highlight different sections of
the music – that’s just one of several
options, all easily accessed via the
interactive menus. Some discs even
come with videos, still photos, and
connections to related websites.
Staggering Sound Realism
With CDs, it’s not unusual to lose
definition in fast-paced passages or
with high-pitched instruments.
DVD-Audio solves that problem. With
a sampling frequency 4.3 times
higher and a resolution 256 times
finer than CDs, DVD-Audio captures
the highest frequency range and
separates individual notes for richer,
cleaner and astoundingly true-to-life
sound. DVD-Audio’s ultra-high
resolution and dynamic range (up to
144 dB compared to CD’s 96 dB) is a
result of up to 24-bit quantisation
and 192 kHz sampling, a significant
advance over the 16-bit and 44.1 kHz
of CDs.
Ultra-high Volume Storage
Imagine an audio disc that
can play continuously 400 minutes of
2 channel stereo sound at 44.1 kHz/
16-bit (audio CD resolution). Or more
than 1 hour of 6 channel 96 kHz/
24-bit or 2 channel 192 kHz/24-bit
audio. A DVD-Audio disc can.
Because discs can hold so much data
– 4.7 Gbytes or almost seven times a
CD when using the single side/single
layer format.
Note: Actual DVD-Audio options will depend on the DVD discs’contents.
