One of the most important commutation elements in a system is a video matrix switch. Thanks to it, any video input may be directed to any output. For example, if you have multiple floor boxes with video inputs, the videos can be directed to any selected screen or projector by connecting a video source to any of the boxes.
When necessary to transmit the image between two remote points, for example, when the normal length of the HDMI cable is not sufficient, converters are used that are connected to each other by network or optical cables, depending on the required transmission distance. With network cables, the transmission distance is usually up to 100 meters, and with optical cables, depending on the operating mode, up to 500 meters or up to 20km.
Where point-to-point video and audio transmission is not sufficient, the recently popular AV over IP transmission method is applied. It allows the use of a conventional network infrastructure to transfer image from one point to another without the using the above components, such as a video matrix switch or conventional video transmission converters.
In a room where an excellent sound quality is required, the use of sound processors is very important as well. Not only do they perform sound commutation and mixing functions but also, based on sophisticated sound processing algorithms, they also enable the adjustment of the sound of the speakers installed in the room to the acoustics of the room. This ensures that the speakers emit an appropriate sound and helps to produce the highest possible sound quality. Audio, based on the same principle as video, may also be transmitted over long distances through the application of the Audio over IP technology, using, for example, DANTE, the most popular protocol.
Customarily, the more complex commutation equipment is used the more difficult it becomes to control such equipment; therefore, video and audio control systems are inevitable in facilitating the control. Often a key element of the control system is a control processor that processes all control commands and is used to physically connect the control system to the devices controlled.
To make such a system easy to use, an integral part of the control system is the control panel, which can have both a touch screen and be operated using buttons. In case of a touch screen panel, Lantel can offer a user-friendly interface that will be tailored to the specific needs of the customer based on the control system purchased. Where a button control panel is selected, the buttons will be assigned predefined functions convenient for users.
