Video information
Component video signal
With the component video signal system, the video signal is separated into
the Y signal for luminance and the P
and P
signals for chrominance.
B
R
Color can be reproduced more faithfully with this system because each of
these signals is independent. The component signal is also called the "color
difference signal" because the luminance signal is subtracted from the color
signal. A monitor with component input jacks is required in order to output
component signals.
Composite video signal
With the composite video signal system, the video signal comprises the
three basic elements of a video picture: color, brightness and
synchronization data. A composite video jack on a video component
transmits these three elements combined.
Compatibility of the input and output video signals
Analog-to-HDMI video conversion is performed according to resolution of video signals as shown below. Analog-to-analog video conversion is also possible when "Analog to Analog Conversion" is
set to "On"
(☞p.
122).

Deep Color
Deep Color refers to the use of various color depths in displays, up from the
24-bit depths in previous versions of the HDMI specification. This extra bit
depth allows HDTVs and other displays go from millions of colors to
billions of colors and eliminate on-screen color banding for smooth tonal
transitions and subtle gradations between colors. The increased contrast
ratio can represent many times more shades of gray between black and
white. Also Deep Color increases the number of available colors within the
boundaries defined by the RGB or YCbCr color space.
HDMI
HDMI (High-Definition Multimedia Interface) is the first industry
supported, uncompressed, all-digital audio/video interface. Providing an
interface between any sources (such as set-top boxes or AV receivers) and
audio/video monitor (such as digital television), HDMI supports standard,
enhanced or high-definition video as well as multichannel digital audio
using a single cable. HDMI transmits all ATSC HDTV standards and
supports 8-channel digital audio, with bandwidth to spare to accommodate
future enhancements and requirements.

APPENDIX
When used in combination with HDCP (High-bandwidth Digital Content
Protection), HDMI provides a secure audio/video interface that meets the
security requirements of content providers and system operators. For
further information on HDMI, visit the HDMI website at
"http://www.hdmi.org/."
S-video signal
With the S-video signal system, the video signal normally transmitted using
a pin cable is separated and transmitted as the Y signal for the luminance
and the C signal for the chrominance through the S-video cable. Using the
S-VIDEO jack eliminates video signal transmission loss and allows
recording and playback of even more beautiful images.
"x.v.Color"
A color space standard supported by HDMI version 1.3. It is a more
extensive color space than sRGB, and allows the expression of colors that
could not be expressed before. While remaining compatible with the color
gamut of sRGB standards, "x.v.Color" expands the color space, and can
thus produce more vivid, natural images. It is particularly effective for still
pictures and computer graphics.
