Each module is described separately below.
The management server 2 is connected with the switch 1 through a network, is a control center of the system, is responsible for management and scheduling of all modules of the whole system, monitoring of the running state, and sends control instructions such as network signal switching rules and network signal switching commands to the switch 1.
The first PC signal source 6 and the second PC signal source 7 are both PCs, i.e. personal computers, for storing audio and video signals. Other devices having the same function may of course be used. The audio and video signals can be separate audio signals and video signals, or can be audio signals and video signals bound together, such as video signals. The computer is adopted as a signal source for convenient control, for example, the computer can receive instructions sent by the management server 2 and the like through the switch 1 and the distributed sending module 3.

The embodiment can adopt the following working modes according to actual conditions.
When the distance between the signal source and the playing device is long, a distributed processing mode is adopted, and the infinite expansion of the geographic position can be realized. Specifically, the first PC signal source 6 directly outputs the audio/video signal to the distributed transmission module 3, the distributed transmission module 3 encodes the audio/video signal and transmits the encoded audio/video signal to the switch 1 through the network, the encoded audio/video signal is switched to the distributed reception module 4 through the switch 1, the encoded audio/video signal is decoded by the distributed reception module 4 and transmitted to the first playing device 8, and the audio/video signal is transmitted and played.

And when the distance between the signal source and the playing equipment is relatively long and the network security requirement is high, a mixed processing mode which is used in a distributed and centralized mode is adopted. The hybrid processing mode has two transmission channels, one is: the audio and video signals output by the first PC signal source 6 are coded by the distributed sending module 3 and then transmitted to the switch 1 through the network, the switch 1 is switched to a centralized processor 5, and the audio and video signals are decoded by the centralized processor 5 and transmitted to a second playing device 9 connected with the switch; the other is as follows: the audio and video signals output by the second PC signal source 7 are directly sent to a centralized processor 5, and then sent to a second playing device 9 connected to the centralized processor 5 after being cut, spliced and the like by the centralized processor 5, or sent to the switch 1 by the network after being encoded by the centralized processor 5, and then switched to the distributed receiving module 4 by the switch 1 to be decoded, and then sent to a first playing device 8 connected to the switch.
When the network of the centralized processor 5 and the switch 1 fails or the decoding function of the centralized processor 5 fails, the output of the distributed receiving module 4 may be used as an input source of the centralized processor 5, and the decoded audio/video signals are cut, spliced and the like by the centralized processor 5 and then sent to the second playing device 9 connected thereto.
As an alternative embodiment, the system further comprises a human-machine interaction module 11 connected to the distributed reception module 4.
