The Indispensable HDMI
The founders of High-Definition Multimedia Interface (HDMI) are Hitachi, Philips, Sony, Silicon Image, RCA, Toshiba and Matsushita Electric Industrial who started the development of HDMI in 2002.
They had something else in mind. They wanted an AV connector that was compatible with DVI. HD TVs at the time used the CEA-861-B video standard. The aim was to improve DVI-HDTV. This would be done by the use of a smaller connector, thereby adding an improvement in audio and electronics control functions.
This they managed to do and today HDMI is that video/audio interface, the digital alternative to what was available only as consumer analog standards being used for S-Video, Radio Frequency, Composite Video, VGA, Component Video or Coaxial Cable. HDMI sends digital data that is uncompressed.
The HDMI interface connects the digital video and audio source to the compatible audio digital devices like televisions and monitors that are digital too.
These audio and digital devices that can be connected to digital TVs and monitors are part of the home theater range such as Video Game Consoles like the XBox 360 and the Playstation 3, AVCHD Camcorders, DVD players, set top boxes and AV receivers.
A Personal Computer or Television in any format supports HDMI with the use of one cable. With the advantage of the 8 digital audio channel reception, a user, with one remote control, can operate all of these devices: Stereo Amplifier, Television, Personal Computer, DVD player, Video Machine, Playstations and Cameras. All can be programmed into one remote control as the format DVI is compatible with HDMI. When a DVI/HDMI adapter is being used this does not affect the quality of the video or audio.
HDMI is an uncompressed connection, so it does not rely on the digital television standards being used by each device. These are DVG and ATSC which are derivatives of MPEG compressed video streams. HDMI decodes these compressed streams and outputs them as uncompressed video streams.
In 2003 HDMI products started arriving on the market, and since then PC companies and more than 850 Consumer Electronics companies are using the HDMI specification. In Europe labels specify whether Televisions are HD ready.
HDMI’s consumer product figures as estimated by LLC who license the specifications for HDMI, announced after receiving a 2008 report from In-Stat who estimated sales of nearly 400 million for HDMI devices in 2009, that all digital Televisions manufactured, would have at least one HDMI input by the end of 2009.
HDMI has won a few awards, one being the Technical Excellence Award, given by PC Magazine. This was for the category of Home Theater in 2008.
PC Magazine, in 2008 awarded a Technical Excellence Award in the Home Theater category for an innovation that has changed the world to the CEC portion of the HDMI specification. The development of HDMI also received an award given to 10 companies, the Technology and Engineering Emmy Award. This was given by the National Academy of Television and Arts Sciences.
