Compare this to digital audio which can be an electrical
signal, but is an indirect representation of sound. See also
“Digital Audio”.
Aspect Ratio
The width of a TV screen relative to its height.
Conventional TVs are 4:3 (in other words, the TV screen is
almost square); widescreen models are 16:9 (the TV screen
is almost twice as wide as it is high).
BD-Java
With some BD which support Java applications, you can
enjoy the interactive functions such as games or
interactive menus.
Blu-ray Disc (BD)
Blu-ray Disc is a next generation optical video disc which is
capable of storing much more data than a conventional
DVD is. The large capacity makes it possible to benefit
from the features such as high-definition videos, multi-
channel surround sounds, interactive menus and so on.
Chapter
Just as a book is split up into several chapters, a title on a
BD-video or DVD-video is usually divided into chapters.
See also “Title”.
Component Video Output
Each signal of luminance (Y) and component (P
B
/C
B
, P
R
/C
R
)
is independent to output so that you can experience
picture Color as it is.
Also, due to compatibility with progressive video (525p/
480p), you can experience higher-density picture than that
in interlace (525i/480i).
Digital Audio
An indirect representation of sound by numbers. During
recording, the sound is measured at discrete intervals
(44,100 times a second for CD audio) by an analog-to-
digital converter, generating a stream of numbers. On
playback, a digital-to-analog converter generates an
analog signal based on these numbers. See also “Sampling
Frequency” and “Analog Audio”.
DNS Server
A server which translates Internet domain names into IP
addresses.
The system to compress digital sound developed by Dolby
