APPENDIX 2 Glossary
Analogue:
Audio (or video) that has not been turned
into numbers. Analogue sound is continuously variable,
while digital sound has specific numerical values.
Analogue audio needs a separate jack for each channel,
whereas digital can carry multi-channel audio in a
“bitstream” via a single jack.
Aspect ratio:
The ratio of vertical and horizontal
dimensions of a displayed image. The horizontal vs.
vertical ratio of conventional TVs is 4:3, and that of
widescreens is 16:9.
Bit Rate:
The amount of data used to hold a given
length of music; measured in kilobits per second, or
kbps. Generally, the higher the bit rate, 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 analogue video
to a TV that has Component Video In jacks. The jacks
are designated Y, Pb and Pr (or sometimes Y/Cb/Cr or
Y/U/V).
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 Coaxial, Optical or HDMI output
connectors. All can carry multi-channel audio.
DivX 3.11/4x/5x:
The DivX code is an MPEG-4 based
video compression technology, developed by DivX
Networks, Inc., that can shrink digital video data to sizes
small enough to be transported over the internet, while
maintaining high visual quality.
Dolby Digital:
A surround sound system developed
by Dolby Laboratories containing up to six channels of
digital audio (front left and right, surround left and right,
center and subwoofer).
DTS:
Digital Theatre Systems. This is another surround
sound system, but it is different from Dolby Digital. The
formats were developed by different companies.
JPEG:
A very common digital still picture format. A
still-picture data compression system proposed by the
Joint Photographic Expert Group, which features small
decrease in image quality in spite of its high
compression ratio.
HDCP: (High-bandwidth Digital Content Protection)
HDCP is a technology used with DVI and HDMI to
prevent unauthorized duplication of digital video and
audio content. HDCP compliance is required on all HDMI
equipment and is an option with DVI equipment. Your TV
must have HDCP or you will not be able to use the
MXV4000’s HDMI output.
LPCM (Linear Pulse Code Modulation):
A system for converting analog sound signal to digital
signal for later processing, with no data compression
used in conversion.
MP3:
A file format with a sound data compression
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 as a regular CD.
Parental Control:
A function of the DVD to limit
playback of a 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 software’s level is higher than the user-
set level.
PCM (Pulse Code Modulation):
See LPCM. In the
context of DVDs and CDs, all PCM is linear.
Playback control (PBC):
Refers to the signal
recorded on video CDs or SVCDs for controlling
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.
Progressive Scan:
Displays all the horizontal lines of a
picture at one time, as a signal frame. The MXV4000
can convert the interlaced video from DVD into
progressive format for connection to a progressive
display. It dramatically increases the apparent vertical
resolution.
Region code:
A system for allowing discs to be
played back only in a specific designated geographical
region. This player will only play discs that have
compatible region codes. You can find the region code
of your player printed or labelled on the rear panel.
Some discs are compatible with more than one region
(or ALL regions).
S-video: (Separated video)
Produces a clear picture
by sending separate signals for the luminance
(light/dark) and the chrominance (colour) information.
Super Audio CD (SACD):
This audio format is based
upon the current CD standards but includes a greater
amount of information that provides higher quality sound.
There are three types of discs: single layer, double layer
and hybrid discs. The hybrid disc contains both standard
audio CD and Super Audio CD information.
Surround:
A system for creating a realistic three
dimensional sound field by arranging multiple speakers
around the listener.
Title:
The longest section of a picture or music feature
on DVD, music, etc., in video software, or the entire
album in audio software. Each title is assigned a title
number enabling you to locate the title you want.
