Glossary

Aspect ratio
A ratio which defines the shape of the rectan-
gular picture in a TV. It is the width of the pic-
ture relative to the height. A conventional TV
picture has 4:3 in aspect ratio.
Bit rate
Shows the number of digital information needed
to play back sound for 1 second. The bit rate
is expressed in bits per second.
Bitstream
The digital form of multichannel audio data (e.g.,
5.1-channel) before it is decoded into its vari-
ous channels.
Chapter/title
Chapter is the smallest division and title is the
largest division on DVD Video. A chapter is a
division of a title and similar to a track for Video
CD or Audio CD.
Component video
Video signals with three separate channels of
information that make up the picture. There are
several types of component video, such as
R/G/B and Y/CB(PB)/CR(PR).
Composite video
A single video signal commonly used in most
consumer video products that contains all lu-
minance, color, and synchronization informa-
tion.
Dolby Digital (AC3)
A six-channel system consisting of left, center,
right, left rear, right rear and LFE (Low-Frequency
Effect channel for use with a subwoofer) chan-
nels. All processing is done in the digital do-
main. Not all Dolby Digital discs contain six
(5.1) channels of information.
Dolby Surround/Dolby Pro Logic
Dolby Surround records four channels of front
and rear audio in two channels in a way that
allows a decoder to recover the original four
channels for playback. Because the audio is
recorded in two channels, it can be played back
by a two-channel stereo system.
Dolby Pro Logic introduces directional circuits
in decoder-side processing (increasing the level
of specific channels and lowering the level of
silent channels) for greater spatial perspec-
tive, and adds a center speaker used prima-
rily for dialog. The result is enhanced chan-
nel separation.
Down-mix
Internal stereo mix of multichannel surround
audio by a DVD player. The down-mix signals
are output from stereo output connectors.
DTS
DTS stands for Digital Theater Systems, a Digital
Surround audio encoding format configured
with six (5.1) channels, similar to Dolby Digi-
tal. It requires a decoder, either in the player
or in an external receiver. Not all DTS discs con-
tain six (5.1) channels of information.
Dynamic range
The difference between the loudest and soft-
est sounds.
Group
The largest division on DVD AUDIO.
Interlaced scanning
In a conventional video system, a picture is
shown on the display monitor in between lines
of two halves. The Interlaced scanning system
places lines of the second half of the picture
in-between lines of the first half of the picture.
JPEG
A popular file format for still image compres-
sion and storage. JPEG stands for Joint Pho-
tographic Experts Group.
There are three sub-types of the JPEG format
as follows.
• baseline JPEG: used for digital cameras, the
web, etc.
• progressive JPEG: used for the web
• lossless JPEG: an old type, rarely used now
Linear PCM audio
PCM stands for "pulse code modulation." Lin-
ear PCM is the usual method for digitally en-
coding audio without compression, and is used
for the audio tracks on DVD Video discs, Au-
dio CDs, etc.
MLP
MLP stands for "Meridian Lossless Packing."
A lossless audio compression system that can
completely recreate the PCM signal.
MP3
MP3 is an audio data compression format,
which stands for MPEG-1 Audio Layer 3. Us-
ing MP3, you can achieve a data reduction of
about 1:10.
34
MPEG
MPEG stands for Moving Picture coding Ex-
perts Group. MPEG is a family of standards
for compressing audio-visual information.
"MPEG" standards include MPEG-1, MPEG-
2 and MPEG-4. Video CD and MP3 are based
on MPEG-1, while DVD is based on MPEG-2.
MPEG Multichannel
This feature expands the 5.1 channel audio
format recorded on the disc to a 7.1 channel
format. The further expansion of the 5.1 channel
audio makes it easy for you to reproduce the
movie theater experience in your own home.
NTSC (National television system
committee - U.S. version)
A black and white and color television system
format used in the U.S.A., Canada, Mexico and
Japan.
PAL (Phase Alternation by Line)
A color television system format used exten-
sively in Western Europe.
PBC
PBC stands for "Playback control" and is a
method of controlling disc play for Video CDs
(VCD). You are able to interact with the disc
through menus.
Progressive scanning
Progressive scanning displays all the horizontal
lines of a picture at one time, as a single frame.
A progressive scanning DVD unit converts the
interlaced video from DVD into progressive
format for connection to a progressive display.
It dramatically increases the vertical resolution.
RGB
An abbreviation for Red, Green and Blue. Color
monitors and color television sets display dif-
ferent hues by mixing these three colors.
S-video
A video signal which improves picture quality
over standard composite connections. Used on
Super VHS, DVD, high end TV monitors, etc.
Track
The smallest division on SVCD, Video CD and
Audio CD discs.
