Definition of Terms
HDMI
HDMI(High Definition Multimedia Interface) is a new
connection format that supports both video and audio
on a single digital connection.
The HDMI connection carries uncompressed,
standard or high definition digital video signals and
multi-channel audio signals to AV components such
as HDMI equipped TVs, in digital form without
degradation.
Since the video signals from HDMI jack are
compatible with the current DVI(Digital Visual
Interface) format, HDMI jacks can be connected to
DVI jacks by way of an HDMI-DVI converter cord.
The HDMI specification supports HDCP(High-
bandwidth Digital Contents Protection), a copy
protection technology that incorporates coding
technology for digital video signals.

Interface are trademarks or registered trademarks of

HDCP
HDCP(High-bandwidth Digital Content Protection) is a
specified method from Intel for protecting copyrighted
digital entertainment content that uses the Digital
Video Interface (DVI) by encrypting its transmission
between the video source and the digital display
(receiver). The video source might be a computer,
set-top box, or digital versatile disc (DVD) player, and
the digital display might be an liquid crystal display
(LCD), television, plasma panel, or projector.
DVI
DVI(Digital Video Interface) is a specification created
by the Digital Display Working Group(DDWG) to
accommodate analog and digital monitors with a
single connector. There are three different DVI
configurations : DVI-A, designed for analog signals,
DVI-D, designed for digital signals, and DVI-
I(intergrated), designed for both analog and digital
signals.
Using a DVI connector and port, a digital signal that is
sent to an analog monitor is converted into an analog
signal. If the monitor is a digital monitor, such as a flat
panel display, no conversion is necessary. Many
monitors now include a DVI connection and many
video adapters include a DVI port along with, or
instead of, the traditional 15-pin Video Graphics Array
(VGA) port.
Component Video
Video signals with three channels of separate
information that makes up the picture. There are
some types of component video, such as
Y/C
B
(P
B
)/C
R
(P
R
) and R/G/B.
Dolby Digital
Dolby Digital provides multichannel surround sound in
cinemas from 35mm film and in the home from laser
discs, DVDs, and digital broadcast television, cable,
and satellite systems. It enables the transmission and
storage of up to five full-range audio channels, plus a
low-frequency effects channel(LFE), thus 5.1
channels, in less space than is required for just one
linear PCM-coded channel on a compact disc.

DTS
DTS(Digital Theater Systems) is a newly-developed
surround system which can handle more amount of
data, providing better audio quality. Though the
number of audio channels is 5.1 which is same as
Dolby Digital, discs bearing the " " provides fat
sound and better signal-to-noise ratio, thanks to the
lower audio compression ratio format. It also provides
wide dynamic range and better separation, resulting
in magnificent sound.

Bitstream
The digital signal form of multichannel audio data
(e.g., 5.1 channel) before it is decoded into its various
channels.
Linear PCM
PCM stands for Pulse Code Modulation. Linear PCM
is the usual digital method without compression, used
for audio playback of audio CDs, DVD Videos, etc.
Packed PCM
A lossless compression system that enables more
PCM audio to be stored on a DVD-Audio disc than
would otherwise be possible.
