With the development of the times, information exchange has become more and more frequent and important, so the AV System(Solution) programmable control host has become more important. Various audio-visual equipment, projection equipment, multimedia control systems and so on began to enter all walks of life. Some large conference rooms are also equipped with simultaneous interpretation systems, electronic voting systems, LCD and LED Video wall projections, and multi-image switching systems. The current meeting rooms and electrical teaching rooms are no longer the old platforms, chairs, and microphones, but all kinds of multimedia conference and teaching equipment. The operation and use of a variety of equipment is also. Such as: to turn on the power of various devices, to turn off the lights, to frequently switch various audio and video signals, to constantly switch the projection screen... and so on. In this case, a control device can centrally manage these devices and control various resources in the conference room and classroom at the same time.

1. The working principle of the AV System(Solution) programmable control host

The AV System(Solution) programmable control host adopts multi-computer communication technology and system integration technology, combines the controlled equipment according to the actual operation requirements of the user, and then integrates the final operation process of each equipment into a simple operation. In short, the programmable central control host can control mixing matrix, VGA centralized control matrix, video booth, projector, electric screen, electric curtain, lighting and other equipment.
