HDTV (High-Denition Television)
It is a digital television broadcasting system
with higher resolution than traditional
television systems (standard-denition TV,
or SDTV). HDTV is digitally broadcast;
the earliest implementations used analog
broadcasting, but today digital television
(DTV) signals are used, requiring less
bandwidth due to digital video compression.
R
RCA (Radio Corporation of America) cables
A standard type of cable used to transmit
analog audio and composite-video signals
between devices such as televisions, satellite
or cable receivers, VCRs, game console
systems, speakers and more. Typical RCA
cables will have two or three color coded
connectors.
RF (Radio Frequency)
It is a frequency or rate of oscillation within
the range of about 3 Hz to 300 GHz. This
range corresponds to frequency of alternating
current electrical signals used to produce and
detect radio waves.
Y
YPbPr
The designation for analog component video
signals. The Y, Pb and P are sets of three
inputs or outputs on better video equipment
and TVs. The three cables used in a YPbPr
connection represent higher quality than the
single-wire composite cable commonly used
to hook up video equipment, because the
brightness and color components of the signal
are maintained separately. The YPbPr signals
are derived from the red, green and blue
(RGB) colors captured by a scanner or digital
camera, and RGB is converted into brightness
and two color difference signals for TV/video.

A
ADSL (Asymmetric Digital Subscriber Line)
It is a data communications technology that
enables faster data transmission over high-
speed broadband networks.
C
CEC (Consumer electronics Control)
CEC is part of the HDMI standard. If CEC
is available in the source and HDTV devices
in your home setup, the devices will be
able to pass commands through the HDMI
connection. Examples of CEC behavior are:
1. Being able to command your source using
the remote of your TV, 2. One-Touch-Play:
by pushing the PLAY button on your source,
your TV will automatically switch to the
corresponding input channel of that source,
3. When the HDTV enters Standby-mode,
the receiver will automatically enter listening
mode.
H
HDMI (High-Denition Multimedia Interface)
It is a high-speed digital interface that can
transmit uncompressed high denition video
and digital multichannel audio. It delivers high
quality picture and sound quality, completely
free from noise. HDMI is fully backward-
compatible with DVI.
As required by the HDMI standard,
connecting to HDMI or DVI products without
HDCP (High-bandwidth Digital Content
Protection) will result in no Video or Audio
output.
