Glossary - Yamaha DVD-S657 Owner's Manual

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.
Chapter: 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
back of the DVD System that send high-quality
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
can shrink digital video to sizes small enough to
be transported over the internet, while maintain-
ing high visual quality.
Dolby Digital: A surround sound system devel-
oped by Dolby Laboratories containing up to six
channels of digital audio (front left and right, sur-
round left and right, center and subwoofer).
DTS: Digital Theatre Systems. This is a surround
sound system, but it is different from Dolby Digi-
tal. The formats were developed by different
companies.
JPEG: A very common digital still picture for-
mat. A still-picture data compression system pro-
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
volume as a regular CD can.
Multichannel: DVD is specified to have each
sound track constitute one sound field. Multi-
channel refers to a structure of sound tracks
having three or more channels.
Parental Control: A function of the DVD to
limit playback of the disc by the age of the users
according to the limitation level in each country.
The limitation varies from disc to disc; when it is
activated, playback will be prohibited if the soft-
ware's level is higher than the user-set level.
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
well as software having a search function.
Play list: A list of selected titles to be played
back in a specific order. This option is only avail-
able with VR format and must be created before-
hand.
