HDMI – What is it actually?  

HDMI stands for High Definition Multimedia Interface and is basically just an interface. In order to be able to use it, additional components such as the HDMI cable, the plug and the HDMI socket are required. It is a modern and sophisticated system that is used to transmit audio and video signals in high quality. For this reason, it is increasingly being used in consumer electronics. However, HDMI technology is also used in video conferencing systems.

HDMI and its areas of application 

Most people have held an HDMI cable in their hands at some point. Both at school and at the office or university, there are HDMI connections almost everywhere. If a presentation is due, an HDMI connection is usually established for it. But even in the private sector, many people use the popular interface and quite a few even without knowing it. How do they do it? By watching television!

The receiver is connected to the TV via an HDMI cable, allowing the user to transmit the image and audio signals to the screen. However, this is not limited to the receiver. For example, if you do not have a Smart TV and normally stream on your laptop, you can also transmit the picture and sound from the laptop to the TV screen via an HDMI connection. Instead of the signals from the receiver, the signals from the laptop are simply transmitted to the screen and the speakers.

As already mentioned, HDMI connections are also used as components for optimal presentation technology. They are used to transfer data from the laptop to the beamer or display in the same way as televisions. For this reason, HDMI connections are also a large and important component of conference room technology. Here, they are used to share knowledge gained with all participants, to hold presentations or to connect with each other via video conferences.

HDMI and its components 

In order to establish an HDMI connection, an HDMI cable and two HDMI sockets are required. The sockets are the connections built into the device into which the cable is plugged. There is therefore an HDMI plug at each end of the cable. The plug and socket can come in four different sizes: Type A, Type C, Type D and Type E.

Type A is the best known and probably most common HDMI size. This type is used in televisions and receivers, for example. Types C and D are both smaller than the previous type, which is why one is used for narrow notebooks and the other for smartphones, for example. Type E, on the other hand, was developed to be installed in vehicles.
