GLOSSARY
■
LFE 0.1 channel
This channel reproduces low-frequency signals. The
frequency range of this channel is from 20 Hz to 120 Hz.
This channel is counted as 0.1 because it only enforces a
low-frequency range compared to the full-range
reproduced by the other 5/6 channels in Dolby Digital or
DTS 5.1/6.1-channel systems.
■
Neo:6
Neo:6 decodes the conventional 2-channel sources for 6-
channel playback by the specific decoder. It enables
playback with the full-range channels with higher
separation just like digital discrete signal playback. There
are two modes available: “Music mode” for music sources
and “Cinema mode” for movie sources.
■
Neural Surround
Neural Surround
™
represents the latest advancement in
surround technology and has been adopted by XM
Satellite Radio for digital radio broadcast of surround
recordings and live events in surround sound. Neural
Surround
™ employs psychoacoustic frequency domain
processing which allows delivery of a more detailed sound
stage with superior channel separation and localization of
audio elements. System playback is scalable from 5.1 to
7.1 multi-channel surround playback.
■
PCM (Linear PCM)
Linear PCM is a signal format under which an analog
audio signal is digitized, recorded and transmitted without
using any compression. This is used as a method of
recording CDs and DVD audio. The PCM system uses a
technique for sampling the size of the analog signal per
very small unit of time. Standing for “Pulse Code
Modulation”, the analog signal is encoded as pulses and
then modulated for recording.
■
Sampling frequency and number of
quantized bits
When digitizing an analog audio signal, the number of
times the signal is sampled per second is called the
sampling frequency, while the degree of fineness when
converting the sound level into a numeric value is called
the number of quantized bits. The range of rates that can
be played back is determined based on the sampling rate,
while the dynamic range representing the sound level
difference is determined by the number of quantized bits.
In principle, the higher the sampling frequency, the wider
the range of frequencies that can be played back, and the
higher the number of quantized bits, the more finely the
sound level can be reproduced.
■
Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the P
B
and P
R
signals for the chrominance. Color can be
reproduced more faithfully with this system because each
of these signals is independent. The component signal is
also called the “color difference signal” because the
luminance signal is subtracted from the color signal. A
monitor with component input jacks is required in order to
output component signals.
■
Composite video signal
With the composite video signal system, the video signal
is composed of three basic elements of a video picture:
color, brightness and synchronization data. A composite
video jack on a video component transmits these three
elements combined.
■
S-video signal
With the S-video signal system, the video signal normally
transmitted using a pin cable is separated and transmitted
as the Y signal for the luminance and the C signal for the
chrominance through the S-video cable. Using the
S VIDEO jack eliminates video signal transmission loss
and allows recording and playback of even more beautiful
images.
