Decoder
A decoder
restores the coded audio signals on DVDs to normal. This is
called decoding.
Dolby
Digital
This is a method of coding digital signals developed
by Dolby
Laboratories.
Apart from stereo (2-channel) audio, these signals can also
be 5.1-channel
sound.
DTS (Digital
Theater
Systems)
This surround system is used in many movie theaters
around the world.
There is good separation between the channels, so realistic sound effects
are possible.
Dynamic
range
Dynamic range is the difference
between the lowest level of sound that
can be heard above the noise of the equipment
and the highest level of
sound before distortion
occurs.
Frame
still and field
still
Frames are the still pictures that go together to make a moving picture.
There are about 30 frames shown each second.
One frame is made up of two fields. A regular television
shows these
fields one after the other to create frames.
A still is shown when you pause a moving picture. A frame still is made up
of two alternating
fields, so the picture may appear blurred, but overall
quality is high.
A field still is not blurred, but it has only half the information
of a frame still
so picture quality is lower.
HDMI
(High-Definition
Multimedia
Interface)
HDMI is a next-generation
digital interface for consumer electronic products.
Unlike conventional
connections,
it transmits uncompressed
digital video
and audio signals on a single cable. This unit supports high-definition
video
output (720p, 1080i, 1080p) from the HDMI AV OUT terminal. To enjoy high-
definition video, a high-definition
compatible television is required.
JPEG
(Joint
Photographic
Experts
Group)
This is a system used for compressing/decoding
color still pictures. The
benefit of JPEG is less deterioration
in picture quality considering
the
degree of compression.
Linear
POM
(pulse
code
modulation)
These are uncompressed
digital signals, similar to those found on CDs.
MR3 (MPEG
Audio
Layer
3)
An audio compression
method that compresses
audio to approximately
one tenth of its size without any considerable
loss of audio quality.
Playback
control
(PBC)
If a Video CD has playback control, you can select scenes and
information
with menus.
Progressive/Interlaced
NTSC, the video signal standard, has 480 interlaced
(i) scan lines,
whereas progressive
scanning uses twice the number of scan lines. This
is called 480p.
Using progressive
output, you can enjoy the high-resolution
video
recorded on media such as DVD-Video.
Your television must be compatible
to enjoy progressive
video.
Sampling
frequency
Sampling is the process of converting
the heights of sound wave (analog
signal) samples taken at set periods into digits (digital encoding).
Sampling frequency
is the number of samples taken per second, so larger
numbers mean more faithful reproduction
of the original sound.
WMA
(Windows
Media
TM
Audio)
WMA is a compression
format developed
by Microsoft Corporation.
It
achieves the same sound quality as MP3 with a file size that is smaller
than that of MP3.
