HDMI  connectors area unit used for the High Definition Multimedia Interface System interface system. this is often a digital methodology of sending audio and visual data. There area unit four main models of instrumentality, tho' solely 3 area unit normally used. The HDMI  instrumentality is just the plug at the tip of AN HDMI cable. like the USB system on computers, it merely plugs in to and pulls out of sockets with no lockup device or clips.

Type A HDMI  instrumentalitys area unit the foremost common connectors and area unit typically brought up as merely the quality connector. it's the plug and socket combination found on most HD connections and, unless a manufacturer specifies otherwise, AN "HDMI  connection" can typically be blood group. The instrumentality has nineteen pins.

Type B HDMI  connectors area unit slightly larger than blood group and have twenty nine instead of nineteen pins. the additional pins enable a "dual link DVI" affiliation that carries a lot of data and means that B connectors will carry double the video detail of blood group. As there's no current demand for such detail, B connectors don't seem to be in common use.

Type C HDMI  connectors area unit terribly almost like blood group, with an equivalent 19-pin set-up. The distinction is that the plug is smaller, measuring .09 in x .41 in (2.42mm x 10.42mm) compared with .18 in x .55 in (4.45mm x 13.9mm). this is often designed to be used principally with moveable devices that don't have the maximum amount area for sockets. A special cable are often wont to convert between kind C and kind A: moreover as adjusting the dimensions, it rectifies the actual fact that the electrical set-up of the pins is slightly completely different within the 2 styles of instrumentality.

Type D HDMI  connectors area unit a good smaller version of blood group and kind C connectors, once more with nineteen pins. These connectors area unit .11 in x .25 in (2.8mm x 6.4mm). this implies that moreover as being smaller, a sort D instrumentality may be a completely different form, being "chunkier" than the comparatively flat blood group and kind C connectors. The variations in size and form between the varied sorts is analogous to the variations between a customary USB plug and a micro-USB plug.

There are plans to develop a replacement, presently anonymous , form of HDMI  instrumentality. this could closely correspond a sort A instrumentality, however would be changed to permit it to lock into place within the socket, preventing it from being knocked out if a cable is accidentally force or nudged. The set up is that this new instrumentality would be backwards compatible and so work with any existing blood group socket.
