En
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
Horizontal and vertical ratio of a displayed image. The
horizontal vs. vertical ratio of conventional TV is 4:3,
and that of wide-screens is 16:9.
Bit
Short for binary digit. Represents the smallest unit of
information manipulated on a computer. In audio
systems, the bit size determines resolution to digitize
analog signals.
The larger the bit size, the larger the dynamic range
(the ratio of maximum and minimum frequency level)
and the finer the sounds. Generally, an audio CD is 16
bit and DVD audio is 24 bit.
Bit rate
The amount of data used to hold a given length of
music; measured in kilobits per second, or kbps. Also,
the speed at which you record. Generally, the higher
the bit rate, or recording speed, the better the sound
quality. However, higher bit rates use more space on a
disc.
COMPONENT VIDEO OUT
Jacks for inputting or outputting a component video
signal.Component video signal consists of three lines,
the luminance signal (Y) and two color difference
signals (P
B
/C
B
, P
R
/C
R
), which enable to provide high-
quality video.
DivX
DivX is a popular media technology created by DivX,
inc. DivX media files contain highly compressed video
with high visual quality that maintains a relatively
small file size. DivX files can also include advanced
media features like menus, subtitles, and alternate
audio tracks. Many DivX media files are available for
download online, and you can create your own using
your personal content and easy-to-use tools from
DivX.com.
Dolby Digital
Digital surround sound system which is developed by
Dolby Laboratories provides completely independent
multi-channel audio. With 3 front channels (left, center,
and right) and 2 surround stereo channels, Dolby
Digital provides five full-range audio channels. With
an additional channel especially for bass effects (called
LFE, or low frequency effect), the system has a total of
5.1-channels (LFE is counted as 0.1 channel). By using
2-channel stereo for the surround speakers, more
accurate moving sound effects and surround sound
environment are possible than with Dolby Surround.
Dolby Surround Pro Logic II
It is an improved matrix decoding technology that
provides better spatiality and directionality on Dolby
Surround programme material; provides a convincing
three-dimensional soundfield on conventional stereo
music recordings; and is ideally suited to bring the
surround experience to automotive sound. While
conventional surround programming is fully
compatible with Dolby Surround Pro Logic II
decoders, soundtracks will be able to be encoded
specifically to take full advantage of Pro Logic II
playback, including separate left and right surround
channels. (Such material is also compatible with
conventional Pro Logic decoders.)
DTS (Digital Theater Systems)
Digital surround sound system developed by Digital
Theater Systems, Inc., which provides 5.1 channel
audio (max). With an abundance of audio data, it is
able to provide authentic-sounding effects.
Interlace
The most common type of scanning used in televisions.
It divides a screen into even and odd numbered fields
for scanning, and then builds an image by combining
them into one image (frame).
JPEG (Joint Photographic Expert Group)
A standardized image compression system proposed by
the Joint Photographic Expert Group. It can reduce
image data sizes to 1 to 10% of their original sizes, and
works on digital photographs effectively.
