What is HDMI?

Advantages of HDMI
The HDMI Founders are Hitachi, Philips, Silicon Image, Sony,
Thomson and Toshiba.
The HDMI Founders began development on HDMI 1.0 on April 16,
2002, with the goal of creating an AV connector .
The first Authorized Testing Centre(ATC), which tests HDMI products,
was opened by Silicon Image on June 23, 2003, in California, United
The first ATC in India was opened by Philips on June 12, 2008, in
The High-Definition Multimedia Interface is provided for
transmitting digital television audio-visual signals from DVD players,
set-top boxes and other audio visual sources to television sets,
projectors and other video displays.
HDMI can carry high quality multichannel audio data and can carry
all standard and high definition electronics video formats.
WHAT is ?
HDMI stand for High-Definition Multimedia Interface.
Include 19 wires wrapped in a single cable. HDMI is able
to carry a bandwidth of 18 Gbps(gigabits per second).
This is more than twice the bandwidth needed to
transmit multichannel audio and video.
HDMI is the first & only industry supported,
uncompressed, all-digital audio/video interface.
WHAT is HDMI ?
HDMI provides an interface between any A/V source, such
as a set-top box, DVD player, or A/V receiver and an audio
and/or video monitor, such as a digital television (DTV),
over a single cable.
HDMI supports standard, enhanced, or high-definition
video, plus multi-channel digital audio on a single cable.
How HDMI Works ?
HDMI uses transition minimized differential signaling
(TMDS) to move information from one place to another.
Transition Minimized Differential Signaling(TMDS) is way
of encoding digital information so that it does not degrade
when the signal travels in cable.
Digital signal in binary form.
How HDMI Works ?
The sending device, such as an HD-DVD player, encodes the
signal to reduce the number of transitions between one (on) and
zero (off).The encoding step helps protect signal quality by
reducing the number of chances for the signal to degrade.
The receiving device, such as an HDTV, decodes the signal. It
measures the difference between the signal and its inverse. It
uses this information to compensate for
any loss of signal along the way.
HDMI 1.4 supported 4K resolutions, yes, but only
at 24 or 30 frames per second.
That works fine for movies, but isn’t useful
for gaming and many TV broadcasts, which
require 50 or 60 fps. Also HDMI 1.4 limited 4K
Ultra HD content to 8-bit color, though it is
capable of 10 or 12-bit color.
HDMI 2.0 fixed all of that because it could handle
up to18 gigabits per second plenty enough to
allow for 12-bit color and video up to 60 frames
Digital Video Interface, or DVI, is actually Father of HDMI.
The first difference is that HDMI technology content security that
is called High Definition Content Protection, also known as HDCP.
The other huge difference between DVI and HDMI is that DVI can
only support digital video, and HDMI can support audio and video
on the same cable.
HDCP stands for High-Bandwidth Digital Content Protection
and was developed by Intel Corporation.
It's nothing more than a security feature requiring between
both the devices the sender and receiver, like HD cable set-
top box and the TV.
It works by encrypting a digital signal with a key that
requires authentication from the transmitting and
receiving product. If authentication fails then the signal
fails, which means no picture on the TV screen.

HDMI is constantly evolving to meet the needs of the
marketplace.HDMI provides a menu of capabilities and allows
the manufacturer to choose which of those features make
sense for its product line. As you upgrade and purchase new
audio and video components, you will notice HDMI becoming
more of a standard connection option with increasing
