Glossary
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 horizontal
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.
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.
XviD: MPEG-4 based video compression
technology, that can shrink digital video 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).
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.
PCM (Pulse Code Modulation): A system for
converting analog sound signal to digital signal
for later processing, with no data compression
used in conversion.
Surround: A system for creating realistic
threedimensional sound fields full of realism by
arranging multiple speakers around the listener.
VIDEO OUT jack: Jack on the back of the DVD
System that sends video to a TV.
HDMI: High Definition Multimedia Interface. A
specification developed by the HDMI Working
Group that combines multi-channel audio and
high definition video and that controls signals
into a single digital interface for use with DVD
players, digital television, and other audiovisual
devices.
H.264: s a next-generation video compression
format. H.264 is also known as MPEG-4 AVC.
Developed for use in high definition systems
such as HDTV, Blu-ray as well as low resolution
portable devices, H.264 offers better quality at
lower file sizes than both MPEG-2 and MPEG-4
ASP (DivX or XviD). H.264 is sometimes referred
(erroneously) as x264 – x264 is the name of a
popular freeware encoder for the H.264 format.
H.264 is also sometimes referred to as MP4,
again this is technically incorrect. MP4 is a
container format much like AVI or MKV and it
can be used to “house” many different types of
compression codecs, not just H.264.
