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 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.
Disc menu
A screen display prepared for allowing selection of 
images, sounds, subtitles, multi-angles, etc. recorded on 
a DVD.
DivX
DivX
®
 is a video compression technology developed by 
DivX
®
Networks, Inc. It compresses digital video data to 
sizes small enough to be transported over the Internet 
without reducing the original video quality. You need 
DivX codec software to play back DivX movies or 
convert data to the DivX format.
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 convertional 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.
MP3 (MPEG Audio Layer-3)
An audio file compression technology. It can reduce 
audio data sizes to about 10% of their original sizes 
while maintaining CD-level audio quality.
MPEG (Moving Pictures Experts Group)
International standard for digital video and audio 
compression generated by ISO (International 
Organization for Standardization) and IEC 
(International Electrotechnical Commission).
Includes MPEG-1, MPEG-2, and MPEG-3. MPEG-1 
offers VHS level video quality and is often used on 
video CDs. MPEG-2 offers S-VHS level video quality 
and is often used on DVDs.
