1. A broadcast major structure comprising a master broadcast control route and a standby broadcast control route; wherein
each of the master broadcast control route and the standby broadcast control route is configured to receive an audio/video broadcast control signal sent from a studio control terminal and play an audio/video file according to the audio/video broadcast control signal,
wherein the master broadcast control route comprises a first optical fiber receiving box, a third network transmission circuit, and a master broadcast control structure sequentially coupled in series,
the first optical fiber receiving box is coupled to the studio control terminal and configured to receive the audio/video broadcast control signal and sequentially transmit the audio/video broadcast control signal to the third network transmission circuit and the master broadcast control structure,
the master broadcast control structure is configured to play the audio/video file under the control of the audio/video broadcast control signal,
the master broadcast control structure comprises a master broadcast controller, a third serial server, an audio/video switcher, a master transmission box and a stage art structure, the master broadcast controller, the audio/video switcher, the master transmission box and the stage art structure are sequentially coupled in series,
the third serial server is coupled to the third network transmission circuit and the audio/video switcher, and is configured to convert a signal in form of TCP/IP protocol text output by the third network transmission circuit into an RS485/RS232 signal and provide the RS485/RS232 signal to the audio/video switcher, with the signal in form of TCP/IP protocol text output by the third network transmission circuit comprising the audio/video broadcast control signal,
the master broadcast controller is coupled to the third network transmission circuit and is configured to store and provide the audio/video file, and
the stage art structure is configured to play the audio/video file provided by the master broadcast controller.
