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 (PB/CB, PR/CR), which enable to provide high-
quality video.

Disc menu

A screen display prepared for allowing selection of 
images, sounds, subtitles, multi-angles, etc. recorded on 
a DVD.

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.

DivX  Ultra

DivX® Ultra Certified products provide enhanced 
playback of advanced media features supported by the 
DivX® Media Format. Key features include interactive 
video menus, subtitles, alternate audio tracks, video 
tags, and chapter points.

DMF (DivX Media Format)

The DivX® Media Format supports advanced media 
features, adding controls for an interactive media 
experience: interactive video menus, chapter points, 
multi-language subtitles, and alternate audio tracks.

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 
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.

HDMI

HDMI (High-Definition Multimedia Interface) is the 
first industry-supported, uncompressed, all-digital 
audio/video interface. Providing an interface between 
any source (such as a set-top box or AV controller) and 
an audio/video monitor (such as a digital television), 
HDMI supports standard, enhanced or high-definition 
video as well as multi-channel digital audio using a 
single cable. HDMI transmits all ATSC (Advanced 
Television Systems Committee) HDTV standards and 
supports 8-channel digital audio, with bandwidth to 
spare to accommodate future enhancements and 
requirements.
When used in combination with HDCP (High-
bandwidth Digital Content Protection), HDMI provides 
a secure audio/video interface that meets the security 
requirements of content providers and system operators. 
For further information on HDMI, visit the HDMI 
website at “www.hdmi.org/”.
