■ AAC (Advanced Audio Coding)
An audio compression scheme defined as part of the
MPEG-2/MPEG-4 standard. AAC supports up to 48
channels and generally achieves better sound quality than
MP3 at the same bit rate.
■ Analog
Sound that has not been turned into numbers.
Analog sound varies, while digital sound has specific
numerical values. These terminals 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 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
Terminals 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
C
, P
/C
), which enable to provide high-quality video.

■ 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 Pro Logic II
It is an improved matrix decoding technology that
provides better spatiality and directionality on Dolby
Surround programmed 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 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
/
B
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.
