HDMI, or High Definition
Multimedia Interface technology
developed by the HDMI Working
Group in 2002, is the newest
digital media interface based on
the DVI-HDCP
model. While
DVI handles only
uncompressed, real-time digital
video, HDMI can handle both
digital video as well as
multi-channel audio. The most
attractive feature of HDMI is
that it has the ability to turn
upwards of 10 separate cables,
audio and video, into one easy
to install, small connector
cable. There are, however, two
HDMI connector types which are
“Type A” which is used for
consumer electronics such as
televisions and DVD players, and
“Type B” which was designed as a
dual link for PC applications
requiring frequencies above 165
MHz.
HDMI has several features that
make it more attractive to the
consumer electronics industry.
Among them are its
Consumer Electronics Control
(CEC) support based on the
AV.link protocol allowing it to
be controlled using a universal
remote, and its bi-directional
communication between HDMI
devices allowing for intelligent
rendering of specified formats.
Also, HDMI, like DVI, transmits
uncompressed high definition
video data therefore the picture
maintains its high quality
without losing color depth, or
altering brightness or
contrast. Also, unlike DVI's 5
meter limit, HDMI cable can be
run up to 15 meters when used
properly.
UPDATE: HDMI 1.3 is the now the
industry standard. This new
version of HDMI cables brings
Higher clock rates (previously
165Mhz, with v1.3 spec is now 340Mhz for singlelink connections and 680Mhz for dual link connections) which increases the
maximum bandwidth of HDMI cables allowing for HDMI to support displays with resolutions that exceed 1080p. While this may seem very complicated, in reality its very simple. A HDMI 1.3 cable if fully backwards compatible with previous version of the HDMI specification, therefore if you need a HDMI cable, buy a HDMI v1.3 and you can rest assured it will work perfectly fine with all your HDMI enabled devices.
UPDATE: Mini HDMI "C" cables are
now available for all your
portable media devices. This is
a more compact design that works
great with portable devices.
More information will be added
shortly including pictures and
detailed information.
