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 BD 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

Component Video Output
Each signal of luminance (Y) and component (PB/CB, PR/CR)
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).
Deep Color
This technology allows expression of more number of
colors than the conventional 8 bits and can reproduce
colors close to natural ones without color 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 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”.
