[0049] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0050] Embodiment 1, Figure 1 The flowchart of an embodiment of the sound reinforcement control method of multiple hosts provided by the present invention is shown. The method is executed by a control server, and the control server is used to control and manage each conference host; each conference host is connected to each other by communication. Figure 1 As shown, the method comprises the following steps:

[0051] Step 110: When a chairperson request is received from a first host, the first host is used as a chairperson host, and a conference host other than the first host is used as a representative host; the first host is any conference host.

[0052] Please refer to Figure 2 , Figure 2 The structure of the conference system is shown. The conference hosts (conference hosts A, B and C) in the same conference system are respectively in rooms A, B and C, and are connected in a cascaded communication manner. Each conference host includes a multicast audio encoding and decoding module. Each conference host uses the same network time protocol (or precision time protocol), real-time transport protocol, clock recovery protocol and network audio transmission protocol. When the multicast audio encoding and decoding module of the conference host receives the analog signal sent by the audio source device, it converts the analog signal into a digital signal and sends the digital signal to the multicast IP address; after the multicast IP address receives the digital signal, it sends the digital signal to the corresponding conference host; after the corresponding conference host receives the digital signal, the multicast audio encoding and decoding module inside the conference host converts the digital signal into an audio signal that can be received by the sound reinforcement device, and plays the audio signal synchronously based on the timestamp of the preset transmission protocol; or, when receiving the play command of the centralized control system, the audio signal is played.

[0053] The audio source devices include but are not limited to: audio acquisition devices such as microphones, wireless microphones and wireless units; the sound reinforcement devices include but are not limited to: speakers and sound columns; the multicast IP addresses include but are not limited to: routers, switches and control servers. In this embodiment, the multicast IP address is the control server.

[0054] In some embodiments of the present invention, the present invention connects each conference host to each other, assigns a corresponding address to each conference host, and sends an audio signal to the conference host with the specified address, so that when holding the same meeting, when multiple conference hosts are located in different conference rooms, the same audio signal can be played synchronously. As long as different conference rooms use the same local area network, multiple conference rooms can hold the same meeting at the same time. In addition, when multiple hosts are used at the same time, one of the hosts is set as the chairman host to control the speaking and sound amplification operations of the representative host, and the authority information of each representative host is set and managed, so as to realize the function of the conference host in one of the conference rooms controlling the conference hosts in the same meeting but located in different conference rooms.

[0055] In some embodiments of the present invention, the control server selects a multicast IP address and a port number that meet the multicast communication protocol. The multicast routing protocol is enabled on the router, and the router is configured to forward multicast traffic to the network segment that needs to receive the multicast data.

[0056] Each conference host is configured with a multicast audio encoding and decoding module and a multicast source; each conference host is configured with a multicast address and port for sending data; each conference host is configured with a multicast receiver for listening to the multicast address and port selected by it.

[0057] Please refer to Figure 3 , Figure 3 A schematic diagram of a sound reinforcement control process of a multi-host management module is shown. The control server is installed with conference host management software, which includes a multi-host management module. The control of the multi-host management module includes steps S310-S350:

[0058] Step S310: Identify all online conference hosts that use the same multicast address, and obtain IP addresses and MAC addresses of all online conference hosts;

[0059] Step S320: receiving a chairperson request from a conference host, selecting a chairperson host for this conference according to the chairperson request, shutting down functions of chairperson function modules of other conference hosts, and only retaining functions of representative function modules;

[0060] Step S330: managing the IP address and MAC address of the representative host participating in this meeting;

[0061] Step S340: managing the rights of the representative host to speak and vote;

[0062] Step S350: Use multicast technology to enable multiple conference hosts to output the same audio in different areas.

[0063] In some embodiments of the present invention, a centralized control server is provided to manage and coordinate the chairman function of each conference host. The centralized control server is responsible for receiving control commands from any conference host. The centralized control server maintains a status list to record the chairman function status of each conference host.

[0064] In some embodiments of the present invention, the control client on each conference host can send control commands to the control server. The control client can receive status updates from the control server. Exemplarily, a user interface is implemented on each conference host to allow the user to request the chairman function or view the current chairman status.

[0065] In an optional manner, when receiving a chairperson request from the first host, after taking the first host as the chairperson host and taking a conference host other than the first host as the representative host, the method further includes:

[0066] Each of the conference hosts is provided with a chairman function module for managing control instructions of the conference host;

[0067] Sending an activation message to the chairman host, so that the chairman host starts the chairman function module of the chairman host when receiving the activation message;

[0068] A closing message is sent to the representative host, so that when the representative host receives the closing message, the chairman function module of the representative host is disconnected.

[0069] In some embodiments of the present invention, a set of control message formats, such as JSON or XML, is defined in the control server for enabling and disabling the chairman function. Exemplarily, an enable message is defined in the control server for enabling the chairman function, and a disable message is defined for disabling the chairman function.

[0070] Based on a message queue or publish-subscribe system (such as RabbitMQ, Apache Kafka, and MQTT, etc.), an open message is sent to the chairman host, or a close message is sent to the representative host; when a first confirmation signal returned by the chairman host is received, it is determined that the open message is sent successfully; when a second confirmation signal returned by the representative host is received, it is determined that the close message is sent successfully.

[0071] In some embodiments of the present invention, each conference host uses a network communication protocol, such as TCP / IP or UDP, to implement communication between the hosts.

[0072] In an optional manner, after the first host is used as a chair host and a conference host other than the first host is used as a representative host, the method further includes:

[0073] According to the preset chairman control protocol, the communication between the chairman host and each representative host is established; the preset chairman control protocol is obtained by setting the preset communication rules and command format.

[0074] In some embodiments of the present invention, a chairperson control protocol is designed, which defines the communication rules and command formats between the chairperson host and other representative hosts.

[0075] Step 120: receiving the control instruction and control address of the chairman host, and sending the control instruction to the representative host corresponding to the control address, so that the corresponding representative host performs the corresponding operation according to the control instruction.

[0076] In an optional manner, receiving the control instruction and the control address of the chairman host, and sending the control instruction to the representative host corresponding to the control address so that the corresponding representative host performs a corresponding operation according to the control instruction, includes:

[0077] receiving a representative start control instruction and a first control address from a chairman host, and sending the representative start control instruction to a representative host corresponding to the first control address to start the corresponding representative host;

[0078] Alternatively, a representative shutdown control instruction and a first control address are received from the chairman host, and the representative shutdown control instruction is sent to a representative host corresponding to the first control address to shut down the corresponding representative host.

[0079] In an optional manner, receiving the control instruction and the control address of the chairman host, and sending the control instruction to the representative host corresponding to the control address so that the corresponding representative host performs a corresponding operation according to the control instruction, includes:

[0080] receiving a speech start control instruction and a second control address from a chairman host, and sending the speech start control instruction to a representative host corresponding to the second control address, so that the corresponding representative host performs an operation of receiving an audio signal, so that when the corresponding representative host receives a target audio signal, the target audio signal is synchronously sent to a conference host corresponding to a listening address; the listening address is sent and obtained by the chairman host;

[0081] Alternatively, a speech closing control instruction and a second control address are received from the chairman host, and the speech closing control instruction is sent to a representative host corresponding to the second control address, so that the corresponding representative host stops performing the operation of receiving audio signals.

[0082] In an optional manner, receiving the control instruction and the control address of the chairman host, and sending the control instruction to the representative host corresponding to the control address so that the corresponding representative host performs a corresponding operation according to the control instruction, includes:

[0083] The voting control instruction and the third control address of the chairman host are received, and the voting control instruction is sent to the representative host corresponding to the third control address, so that the corresponding representative host performs the operation of receiving the voting signal.

[0084] In an optional manner, receiving a transmission instruction and a transmission address of an audio signal from a second host, and synchronously sending the audio signal to a conference host corresponding to the transmission address based on the authority information of the second host, or not transmitting the audio signal, includes:

[0085] If the permission information of the second host includes permission to speak, sending the audio signal to the conference host corresponding to the transmission address;

[0086] If the authority information of the second host includes prohibition of speaking, the audio signal is not transmitted.

[0087] Specifically, the chairman host of the present invention controls the operations of opening, closing, voting, speaking and sound amplification of the representative host; and sets the permission information of each representative host to control the sound amplification function of each representative host, so as to realize the function of the conference host in one conference room controlling the conference hosts in the same conference but located in different conference rooms.

[0088] Specifically, the present invention periodically or variably synchronizes the states of all representative hosts to ensure that the control commands of the chairman host are correctly executed, thereby improving the stability of controlling each conference host.

[0089] In some embodiments of the present invention, the chairman function of the chairman host includes: management of the speaking right of the representative host. The representative host has a speaking request function, and the representative host requests the speaking right from the chairman host. Optionally, the chairman host sends a speaking start control instruction to the representative host according to the request of the representative host, and sets the authority information of the representative host to allow speaking.

[0090] In some embodiments of the present invention, the chairman function of the chairman host includes: conference control capability.

[0091] The chairman host broadcasts control commands to all conference hosts through the multicast address. The control commands include but are not limited to: turning on or off the representative function, requesting to speak, and voting control, etc. All representative hosts connected to the multicast address will receive these commands. The representative host continuously monitors the messages on the multicast address and performs corresponding operations according to the received commands.

[0092] In some embodiments of the present invention, control messages are encrypted to ensure communication security, implement an authentication mechanism, and prevent unauthorized hosts from sending control commands.

[0093] In an optional manner, after receiving the control instruction and the control address of the chairman host, and sending the control instruction to the representative host corresponding to the control address so that the corresponding representative host performs a corresponding operation according to the control instruction, the method further includes:

[0094] Detect the working status of each representative host. If it is detected that the working status of any representative host does not meet the preset working status, and the preset working status is determined according to the control instruction, then control the corresponding representative host to perform the corresponding operation again according to the control instruction, or report an error.

[0095] In some embodiments of the present invention, the chairman host needs to synchronize the status of all representative hosts periodically or frequently to ensure that the control command is correctly executed.

[0096] Step 130: Receive the transmission instruction and transmission address of the audio signal of the second host, and based on the permission information of the second host, send the audio signal to the conference host corresponding to the transmission address, or do not transmit the audio signal; the second host is any conference host; the permission information of the second host is managed by the chairman host.

[0097] In an optional manner, the audio signal is sent to a conference host corresponding to the transmission address, so that the conference host corresponding to the transmission address plays the audio signal synchronously based on a timestamp of a preset transmission protocol;

[0098] Alternatively, the audio signal is sent to a conference host corresponding to the transmission address, so that the conference host corresponding to the transmission address plays the audio signal when receiving a play command from a centralized control system.

[0099] In some embodiments of the present invention, the present invention uses the Network Time Protocol (NTP) to synchronize audio playback between different conference hosts. The specific steps include:

[0100] The present invention determines an accessible and normally running NTP server; installs NTP client software on each conference host, configures each conference host to synchronize time with the NTP server regularly, uses the ntpq command on Linux or the "date and time" setting on Windows to check whether each host has successfully synchronized time, and ensures that the time deviation of all conference hosts is within a preset range, usually a few milliseconds.

[0101] Among them, all conference hosts use the same audio playback software and setting parameters. Before playing audio, all conference hosts should pre-load audio files and be ready to play. Appropriate buffer size can be set to absorb network delay and jitter.

[0102] In some embodiments of the present invention, the NTP synchronization status is checked regularly to ensure that the time is always synchronized; and necessary maintenance is performed on the NTP server and the client.

[0103] The present invention uses NTP timestamp to trigger the synchronous audio playback of the conference host.

[0104] In an optional manner, the playback operations of each conference host are synchronously detected. If it is detected that the playback operation of any conference host is out of synchronization, the NTP setting or audio playback buffer size of the corresponding conference host is adjusted to synchronize the playback operations of each conference host.

[0105] In some embodiments of the present invention, the present invention installs centralized control system software in the control server, installs and configures a control receiver on each conference host to enable it to receive commands from the centralized control system. The control server sets control logic in the centralized control system to send a play command to all conference hosts.

[0106] In some embodiments of the present invention, any conference host (for example, conference host A) uses an audio source device to collect a first audio signal (analog signal). When receiving the first audio signal, the multicast audio codec module of conference host A converts the first audio signal into a digital signal, transmits the digital signal to the control server through multicast technology, and sends the transmission instruction and transmission address of the first audio signal to the control server, for example, the transmission address is the address of conference hosts B and C. The control server searches for the authority information of conference host A managed by the chairman host. If the speaking authority of conference host A is permitted, the control server sends the digital signal to conference host B and conference host C. When conference host B and conference host C receive the digital signal, they use their respective multicast audio codec modules to convert the digital signal into an audio signal that can be received by the sound reinforcement device, and synchronously play the audio signal through the sound reinforcement device based on the timestamp of the preset transmission protocol; or, when receiving the play command of the centralized control system, play the audio signal through the sound reinforcement device.

[0107] The present invention connects each conference host through communication, assigns a corresponding address to each conference host, and sends an audio signal to the conference host with the specified address, so that when holding the same meeting, when multiple conference hosts are located in different conference rooms, the same audio signal can be synchronously played. As long as different conference rooms use the same local area network, multiple conference rooms can hold the same meeting at the same time. In addition, when multiple hosts are used at the same time, one of the hosts is set as the chairman host to control the speaking and sound amplification operations of the representative host, and the authority information of each representative host is set to realize the function of the conference host in one of the conference rooms controlling the conference hosts in the same meeting but located in different conference rooms, so as to improve the management efficiency of the sound amplification management of multiple conference rooms.
