HDMI which stands for High-Definition Multimedia Interface is a system developed for transmitting uncompressed digital signals between a host of compatible audio video devices. The HDMI to DVI cable was introduced late in 2003 around about the time that High Definition Television was becoming popular.
The cable is able to connect most set-top boxes, Xboxes, Play Stations and DVD players as well as Audio Video type receivers to computer monitors, HDTV's and other consumer AV equipment.
On one cable, any PC or TV video format can be supported. This includes up to eight channels of uncompressed or compressed digital audio and a CEC (Consumer Electronics Control) connection. This CEC connection has the capability of allowing various high definition devices to control one another and gives the user the ability to operate several devices using only one remote control.
Because DVI (Digital Visual Interface) and HDMI signals are electrically compatible, it is not necessary to convert the signals. Also, there is no video quality loss suffered by using the adapter cable. The current standard for the high definition interface is fast becoming the digital replacement for co-axial cable, S-Video, composite video, VGA, D-Terminal and SCART.
Rapidly approaching the de facto industry standard for HDTV, the marketing group In-Stat says that ninety percent of all high-definition TV sets manufactured in 2007 were fitted with the interface. Subsequently, In-Stat reported that 229 million of the devices were purchased in 2008 followed by a further 394 million in 2009. They further predicted that by the end of 2009 every digital TV would have HDMI installed.
There are four types of connectors and they have been named A, B, C and D. Type A is a nineteen pin connection and is DVI-D compatible. Type B is a twenty nine pin connection but carries a video bandwidth double that of Type A. Type C is a mini nineteen pin connection and is used by portable units. Type D is the latest nineteen pin connection, but the plug itself is a micro version and resembles a micro-USB plug.
There are several versions of the HDMI standard with each version being allocated a number. Currently versions 1.0 to 1.2, 1.3 and 1.4 are available with all of the versions using the same cable but having increased bandwidth and capabilities for each subsequent version number. Although a maximum length for the cable has not been specified, resistance in the cable and the way it has been manufactured together with the materials used, places a limit on usable lengths. HDMI to DVI cable is currently manufactured in lengths ranging between 5 and 15 meters.
