traversing a high speed serial bus,
such as IEEE-1394

channel and display). Using E-DDC,
the video source can read the EDID
information form the display.

HDCP
High-bandwidth Digital Content
Protection: A “key” encoded into the
HDMI/DVI signal that prevents video
data piracy. If a source is HDCP coded
and connected via HDMI/DVI without
the proper HDCP decoding, the
picture is put into a “snow vision” mode
or changed to a low resolution. For
normal content distribution the source
and the display device must be
enabled for HDCP “software key”
decoding.

ITU-656
The ITU Radio communication Sector
(ITU-R) is a standards body
subcommittee of the International
Telecommunication Union relating to
radio communication. ITU-656 (a.k.a.
SDI), is a digitized video format used
for broadcast grade video.
Uncompressed digital component or
digital composite signals can be used.
The SDI signal is self-synchronizing,
uses 8 bit or 10 bit data words, and has
a maximum data rate of 270 Mbit/s,
with a minimum bandwidth of 135
MHz.
