x Broadband
General name for communication lines that
use a broad frequency bandwidth for sending
and receiving large amounts of video or audio
data at high speed. Currently, ADSL, CATV,
FTTH and other systems are identified as
broadband.

x Broadband router
For Internet connections through ADSL or a
cable TV line, devices called ADSL modems
or cable modems are used. However, for
Internet access from multiple terminals
connected at once, a broadband router is used.

x Component video
A format for transmitting video signal
information consisting of three separate
signals: luminance Y, chrominance Pb, and
chrominance Pr. High quality pictures, such as
DVD video or HDTV pictures, are transmitted
more faithfully. The three jacks are color-
coded green, blue, and red.

x Composite video
A standard format for transmitting video
signal information. The luminance signal Y
and chrominance signal C are combined and
transmitted together.

x Crossover frequency
The frequency at which two speaker’s
frequencies intersect.
frequencies intersect.
x Deep Color
Video signals for which the color depth of
signals passing through an HDMI jack have
been raised.
The number of colors that could be expressed
by 1 pixel was 24 bits (16,777,216 colors) with
the current HDMI jack. However, the number
of colors which can be expressed by 1 pixel
will be 36, etc., bits when the receiver
corresponds to Deep Color.
Since the gradation of the depth of a color can
be expressed more finely with more bits,
continuous color changes can be more
smoothly expressed.

Abbreviation of Dynamic Host Configuration
Protocol.
A set of rules to automatically assign settings
necessary for network communication.

x Digital Concert Hall
“Digital Concert Hall” delivers richer sound
for 2ch stereo sources such as CDs, etc. With
the use of 5.1ch or 7.1ch speakers and virtual
speaker technology, stereoscopic
reverberation and reflected sound are
reproduced, and music software can be
enjoyed with richer sound and presence. The
sound field in a concert hall is recreated by a
geometrical analysis of the concert hall and
precise modeling of reflected and reverberant
sounds based on actual measured data. Tonal
qualities such as sound strength and frequency
response are taken into account and calculated
on the DSP (Digital Signal Processor) to bring
reverberation in. Sound is enjoyed with natural
and comfortable resonance, as if listening to
music in a concert hall.
