Glossary - Onkyo BD-SP808 Instruction Manual

Analogue Audio
An electrical signal that directly represents sound.
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).
AVCHD
AVCHD is a new format for high definition video
camcorders which can record and play high-resolution HD
images.
BD-Java
With some BDs which support Java applications, you can
enjoy the interactive functions such as games or
interactive menus.
BD-Live
BD-Live is a BD-video (BD-ROM version 2 Profile 2.0/
Profile 1.1) which contains new functions (e.g. Internet
connection), in addition to the BONUSVIEW function.
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. 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
is independent to output so that you can experience
picture colour as it is.
Also, due to compatibility with progressive video (480p/
576p), you can experience higher-density picture than that
in interlace (480i/576i).
Deep Color
This technology allows expression of more number of
colours than the conventional 8 bits and can reproduce
colours close to natural ones without colour streak.
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 analogue-to-
digital converter, generating a stream of numbers. On
playback, a digital-to-analogue converter generates an
analogue signal based on these numbers. See also
"Sampling Frequency" and "Analogue Audio".
DivX
®
DivX is a codec (compression/decompression) that can
®
compress pictures to a very small amount of data. The
software can compress video data from almost any
devices to the size that can be sent on the Internet without
compromising visual quality of the pictures.
