HDMI stands for High Definition Multimedia Interface , the most commonly used HD signal for transmitting HD audio and video over a single cable. It is used in both the commercial AV world and is the most common cable used in the home to connect devices such as digital TVs, DVD players, Blu-ray players, Xbox, Playstation and AppleTV to TVs.
HDMI is a digital interface, single-cable solution for combining HD video and audio, replacing analog solutions that require separate audio/video cables (such as VGA and audio jacks).
Use the HDMI cable to connect the output of your HD source to the input of our HD displays - whether it's your TV, business screen or projector, all the way to a multi-screen video wall! HDMI cables will also be used for AV/home entertainment systems if the system includes additional control or signal distribution devices such as signal splitters, HDMI switchers or AV matrices.
The standard 14mm version of the HDMI connector is called "Type A" and can be used as a "plug" or "male" connector on the cable. A normal HDMI cable usually has a plug on both ends and an HDMI Type A socket on the AV device (source, monitor, screen, TVG, etc.).
The HDMI Type A connector is the most common version and can be found on most AV equipment and devices, from your TV, Blu-ray and XBox to professional distribution devices such as HDMI distribution amplifiers, matrix devices and signal switchers.
But there are also HDMI Mini ( Type C ) and HDMI Micro ( Type D ) HDMI connector versions available, as smaller and smaller devices, such as our smartphones and tablets, are increasingly becoming our personal HD AV sources.
With recommended transmission distances of only 5 to 10 meters (preferably 20 meters) using standard HDMI cables, getting the HDMI source signal to the screen often seems to be a challenge. But they are many devices and technologies - from simple equalizers and repeaters, to the latest Ethernet or optical HDMI - that can increase your signal transmission distance to hundreds of meters!
-Use HDMI switchers and repeaters; this will effectively "amplify" or recalculate your HDMI signal, thus improving and extending the transmission.
- Using the latest HDMI-over-Ethernet cables or HDBaseT technology.
- With HDBaseT technology, you can extend your signal up to an incredible 100 meters over standard Category 5e, 6 or 7 Ethernet cables.
Of course, while HDMI carries both video and audio signals, in some (commercial) applications you may need to embed alternative audio signals (for example, a sports bar that displays a sports TV channel but plays music from a different source).
Whether for commercial or residential systems, the number of AV sources and display devices we have is constantly increasing. As a result, many integrated systems need to be able to switch and change between which source is transmitted to which monitor or TV.
HDMI switchers, matrix devices and the latest software solutions provide management, control and distribution for the ever-growing number of multi-device AV systems.
