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 its height).
AVCHD
AVCHD is a new format for high definition video
camcorders which can record and play high-resolution HD
images.
BD-Live™
BD-Live™ is a BD-video (BD-ROM version 2 Profile 2.0)
which contains new functions (e.g. Internet connection), in
addition to the BONUSVIEW™ function.
Blu-ray Disc™
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 (PB/CB, PR/
CR) 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).
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”.
