Analog: Sound that has not been turned into
numbers. Analog sound varies, while digital
sound has specific numerical values. These jacks
send audio through two channels, the left and
right.
Aspect ratio: The ratio of vertical and hori-
zontal sizes of a displayed image. The horizontal
vs. vertical ratio of conventional TVs. is 4:3, and
that of widescreens is 16:9.
AUDIO OUT Jacks: Jacks on the back of the
DVD System that send audio to another system
(TV, Stereo, etc.).
Bit Rate: The amount of data used to hold a
given length of music; measured in kilobits per
seconds, or kbps. Or, the speed at which you
record. Generally, the higher the bit rate, or the
higher the recording speed, the better the sound
quality. However, higher bit rates use more space
on a Disc.
Cha
pter: Sections of a picture or a music piece
on a DVD that are smaller than titles. A title is
composed of several chapters. Each chapter is
assigned a chapter number enabling you to locate
the chapter you want.
Component Video Out Jacks: Jacks on the

video to a TV that has Component Video In jacks
(R/G/B, Y/Pb/Pr, etc.).
Disc menu: A screen display prepared for
allowing selection of images, sounds, subtitles,
multi-angles, etc. recorded on a DVD.
Digital: Sound that has been converted into
numerical values. Digital sound is available when
you use the DIGITAL AUDIO OUT COAXIAL
or OPTICAL jacks. These jacks send audio
through multiple channels, instead of just two
channels as analog does.
DivX 3.11/4x/5x: The DivX code is a patent
pending, MPEG-4 based video compression tech-
nology, developed by DivXNetworks, Inc., that

be transported over the internet, while maintain-

posed by the Joint Photographic Expert Group,
which features small decrease in image quality in
spite of its high compression ratio.
MP3: A file format with a sound data compres-
sion system. “MP3” is the abbreviation of Motion
Picture Experts Group 1 (or MPEG-1) Audio
Layer 3. By using MP3 format, one CD-R or CD-
RW can contain about 10 times as much data

activated, playback will be prohibited if the soft-

PCM (Pulse Code Modulation): A system for
converting analog sound signal to digital signal for
later processing, with no data compression used
in conversion.
Playback control (PBC): Refers to the signal
recorded on video CDs or SVCDs for control-
ling reproduction. By using menu screens
recorded on a Video CD or SVCD that supports
PBC, you can enjoy interactive-type software as
