In step S11, the outgoing device probe packet is, for example, a timing-outgoing device probe packet. The device detection packet is, for example, a broadcast packet based on a UDP protocol, data communication is performed by selecting the UDP protocol, and when the video console and the external device are in a local area network, namely, the same network segment, the video console and the external device can be actively discovered mutually, so that the complexity of field use of a user is reduced, and additional configuration information is reduced. The mentioned at least one external device comprises at least one media server, at least one video processing device and/or at least one light host machine. The mentioned device probe packet includes, for example, a first data packet header and a first data region based on the TLV data structure, where the first data packet header includes, for example, a first communication protocol identifier, a protocol version number, a sequence number of the packet, and the like. The TLV data structure refers to a structure composed of a data type Tag, a data Length, and a data Value, wherein the first data area includes, for example, a first service type identifier, a service data Length, service data, and the like.

In other embodiments of the present invention, step S12 includes, for example: analyzing the equipment detection reply packet to obtain a second data packet header and a second data area; judging whether a second communication protocol identifier in the second data packet header is the same as the first communication protocol identifier; responding to that the second communication protocol identifier is different from the first communication protocol identifier, and judging that the external device corresponding to the device detection reply packet is not the target adding device; in response to the second communication protocol identification being the same as the first communication protocol identification, determining whether the second data region is based on the TLV data structure; in response to the second data region not being based on the TLV data structure, the external device to which the device probe reply packet corresponds is not the target add device; in response to the second data region being based on the TLV data structure, determining whether a second traffic type identifier in the second data region is the same as the first traffic type identifier; responding to that the second service type identifier is different from the first service type identifier, and judging that the external device corresponding to the device detection reply packet is not the target adding device; responding to that the second service type identification is the same as the first service type identification, and taking the external device corresponding to the device detection reply packet as the target adding device.
It can be understood that the device probing reply packet replied by each external device includes a second data packet header and a second data area, wherein only the external device corresponding to the device probing reply packet whose second communication protocol identifier is the same as the first communication protocol identifier in the device probing packet, the second data area is based on a TLV data structure, and the second service type identifier in the second data area is the same as the first service type identifier in the device probing packet is a target adding device, and can be controlled by the video console, when the external device needs to be controlled by the video console, only the data packet structure corresponding to the video console needs to be developed to the external device, that is, the communication protocol identifier in the reply packet corresponding to the external device is the same as the communication protocol identifier of the video console, the data area is the TLV data structure, and the corresponding service type identifier is the same as the service type identifier output by the video console, the communication connection between the external equipment and the video control console can be established, and then the video control console can control the external equipment.
For example, a first communication protocol identifier in a device probe packet sent by the video console is, for example, a first service type identifier is, for example, B, the video console is, for example, connected with 4 external devices, and receives a device probe reply packet input by each of the 4 external devices, where a second communication protocol identifier included in the device probe reply packet input by the external device 1 is, for example, C, then the external device 1 is not a target adding device, a second communication protocol identifier included in the device probe reply packet input by the external device 2 is, for example, a, but the second data area is not a TLV data structure, then the external device 2 is not a target adding device, a second communication protocol identifier included in the device probe reply packet input by the external device 3 is a, and the second data area is a TLV data structure, and a second service type identifier in the second data area is D, if the external device 3 is not a target adding device, the second communication protocol identifier included in the device detection reply packet input by the external device 4 is a, the second data area is a TLV data structure, and the second service type identifier in the second data area is B, then the external device 4 is a target adding device, wherein the device detection reply packet replied by the external device 4 further includes service data content, for example, the service data content includes the name of the computer where the external device 4 is located, the IP of the computer where the external device is located, the software name, the software version number, and other content.
In other embodiments of the present invention, step S13 includes, for example: and adding the at least one target adding device into the device control list, and displaying the device type, the device name, the device address and the device state corresponding to each target adding device.
The types of devices mentioned include, for example: media server, light host, audio console, etc. The mentioned device names include, for example, custom names, or device models, etc. The mentioned device address is, for example, an IP address corresponding to the device in the same network. The device status mentioned is for example an online status or an offline status, etc.
It is understood here that the video console is provided with a display screen, for example a liquid crystal display screen, or an LED display screen, wherein the display screen is for example a touch display screen. The display screen displays an equipment control list, and the equipment information corresponding to the target adding equipment is displayed in the equipment control list, wherein the equipment information comprises equipment type, equipment name, equipment address and equipment state, so that an operator can know basic information of the target adding equipment conveniently. In addition, the target adding devices may be classified and managed by device types, that is, the target adding devices of the same type are located in the same pull-down menu, and the name of each pull-down menu is the name of the device type corresponding to the included device, and the device name and the device address corresponding to each target adding device are displayed in a frame corresponding to the target adding device, for example, the device status may also be directly displayed in the frame, or the frames may be labeled with different colors to represent different device statuses of the target adding device. Therefore, the operators can conveniently carry out classification management on the target adding equipment.
In other embodiments of the present invention, the at least one target adding device includes at least one media server, for example, and the foregoing step S14 includes: selecting a first media server from the equipment control list as the current control equipment according to the first human-computer interaction operation; and acquiring a plurality of playing programs corresponding to the first media server, and displaying a program thumbnail corresponding to each playing program.
The mentioned media server is, for example, a server storing a plurality of broadcast programs, and it is understood herein that the programs displayed on the LED display screen all come from the media server. Where the video console and the media server establish a connection, for example through a switch or router. The mentioned broadcast program includes, for example, a plurality of media and content such as attribute information related to each media. The mentioned plurality of broadcast programs may be understood as the entire broadcast program of the first media server. By acquiring a plurality of broadcast programs and displaying the program thumbnail corresponding to each broadcast program, the operator can be helped to better and more quickly know the related content of the broadcast programs.
In another embodiment of the present invention, after the obtaining of the plurality of broadcast programs corresponding to the first media server, for example, the method further includes: receiving program change information sent by the first media server after the self-played program changes; and updating the plurality of playing programs and the displayed program thumbnails based on the program change information.
When the program information of the first media server changes, such as modifying or deleting a certain playing program, the first media server reports the program change information to the video console actively, so that the playing programs of the video console and the media server are ensured to keep synchronous in real time. The program change information mentioned above includes, for example, information such as the total number of current programs, the program ID index, the program ID, the program name, and whether the current program is a null program.
In other embodiments of the present invention, step S15 includes, for example: binding the plurality of playing programs and the plurality of keys in a one-to-one correspondence manner according to a third man-machine interaction operation; responding to a first key triggering operation of a user, and determining a target playing program corresponding to the first key; and responding to the pushing operation of a control lever of a user, issuing a program switching instruction to the first media server, so that the first media server switches the currently played program to the target played program corresponding to the first key according to the program switching instruction.
The third mentioned man-machine interaction operation is, for example, an operation of dragging a playing program to a button by a mouse, or a click operation of the mouse, and the like. The video console comprises a plurality of keys and a control rod, for example, and a plurality of playing programs are bound with at least some keys in the keys one by one, so that program switching can be completed quickly based on the keys.
It can be understood here that the video console is provided with a plurality of keys and a control lever, and when the user selects the first media server to obtain the corresponding plurality of broadcast programs, the user may operate on the human-computer interaction interface to bind the plurality of broadcast programs and the plurality of keys in a one-to-one correspondence manner, for example, click the broadcast program frame and the key frame respectively to complete the binding. Although the invention is not limited to the binding. After the binding is completed, the user may control the first media server to perform a program switching operation, for example, the user presses a first key at present, the video console determines a target broadcast program corresponding to the first key, and generates a program switching instruction accordingly, and then the user pushes the control lever, and the video console issues the program switching instruction to the first media server to perform the program switching. Therefore, the program switching of the media server is simply and quickly completed. It should be noted that each key may bind to the broadcast programs corresponding to different media servers, and when the same key binds to the broadcast programs corresponding to different media servers, the user switches the media servers, and the broadcast programs bound to the key are also correspondingly switched.
Further, the aforementioned binding of the plurality of broadcast programs and the plurality of keys in a one-to-one correspondence according to the third human-computer interaction operation includes, for example: and displaying the program name of each playing program in the display area of the corresponding bound key.
It can be understood here that each key includes a display area for displaying some basic information, and when the playing program is bound with the key, the current control device is the first media server, and then the display area of the corresponding key will display the program name of the playing program corresponding to the bound first media server, so as to help an operator to know the playing program and complete the program switching quickly according to the key.
For better understanding of the present embodiment, a specific implementation of the multi-device control method disclosed in the first embodiment of the present invention is illustrated below with reference to fig. 2 to 4.

As shown in fig. 2, the video console is connected to the media server 1, the media server 2, the media server 3, the light host 1, and the light host 2 through a switch or a router. In order to reduce the complexity of the field use of a user and reduce additional configuration information, a data communication mode selects UDP transmission, and when a video console and external equipment are in a local area network (particularly in the same network segment), the video console and the external equipment can be actively discovered mutually.
The video console can perform equipment search regularly, specifically, the video console sends out equipment detection packets regularly in a broadcasting mode, the external equipment in the same network segment receives the equipment detection packets and replies the equipment detection reply packets, namely, the media server 1 receives the equipment detection packets and replies the first equipment detection reply packets, the media server 2 receives the equipment detection packets and replies the second equipment detection reply packets, the media server 3 receives the equipment detection packets and replies the third equipment detection reply packets, the lighting host 1 receives the equipment detection packets and replies the fourth equipment detection reply packets, and the lighting host 2 receives the equipment detection packets and replies the fifth equipment detection reply packets. Therefore, the video console can maintain and manage all the external devices in the local area network. It is assumed that the data area of the device probe reply packet replied by each offboard device is based on the TLV data structure.
The video console automatically adds the external device conforming to the protocol to the device control list, and specifically, the video console analyzes the received device detection reply packet. For example, the video console parses a first device detection reply packet to obtain a communication protocol identifier a and a service type identifier B, parses a second device detection reply packet to obtain a communication protocol identifier C and a service type identifier D, parses a third device detection reply packet to obtain the communication protocol identifier a and the service type identifier B, parses a fourth device detection reply packet to obtain the communication protocol identifier a and the service type identifier B, and parses a fifth device detection reply packet to obtain the communication protocol identifier C and the service type identifier D, and a device detection packet output by a built-in protocol of the video console includes the communication protocol identifier a and the service type identifier B, so that the media server 1, the media server 3, and the light host 1 are added to the device control list as target adding devices. As shown in fig. 3, at this time, for example, the device types and device names corresponding to the media server 1, the media server 3, and the lighting host 1 are displayed in the device control list, and in addition, the device IP and the device status (not shown in the figure) are also displayed, the external devices of the same device type are located under the same pull-down menu, and the pull-down menu is named as the device type, that is, the media server 1 and the media server 3 are located under the pull-down menu named as the media server, and the lighting host 1 is located under the pull-down menu named as the lighting host. Different states of the same device display different colors, for example, or the device state is directly identified in a frame corresponding to the device, and as data interaction between the devices is bidirectional, the video console can acquire other information such as the current busy state of the device in real time.
The user selects the media server 1 as a current control device in the device control list, for example, a mouse clicks a frame corresponding to the media server 1, the video console acquires all the broadcast programs corresponding to the media server 1, and displays a program thumbnail corresponding to the broadcast program, so that the user can know the relevant information of the broadcast program of the media server 1.
At this time, it should be noted that, if the method for playing the program of the media server 1 changes, for example, a certain playing program is deleted or modified, the media server 1 may actively report to the video console, for example, a program change instruction or a currently playing program is sent to the video console, and thus the video console may update the playing program corresponding to the media server 1, and further update the program thumbnail, thereby ensuring that the programs of the media server 1 and the video console are kept synchronized in real time.
As shown in fig. 4, a user operates on the human-computer interaction interface to perform one-to-one associated binding between each playing program of the media server 1 and the key, for example, the user selects a certain playing program by using a mouse and then drags the certain playing program to the corresponding key area to complete the binding. For example, the media server has, for example, 10 programs, the video console has, for example, 18 bindable keys, and the user can freely bind the programs and the keys, for example, drag the program 1 to the area corresponding to the key 1, that is, complete the binding of the program 1 and the key 1, and sequentially bind the programs 2 to 10 to the keys 2 to 10, but the listed programs may also be bound to other keys. After the binding is finished, the video console can automatically store the binding relationship.
It is worth mentioning that when a user switches the current control device from the media server 1 to the media server 2, the video console may also obtain all the broadcast programs of the media server 2, and then bind with the keys based on the human-computer interaction operation, and the same key of one video console allows binding of the broadcast programs corresponding to multiple media servers, thereby achieving the purpose of establishing a mapping relationship between the broadcast programs on all the media servers and the buttons of the video console. When a user selects a certain media server in the device control list, the binding relationship of the key is automatically switched to the binding relationship of the media server.
In addition, each key of the video console includes, for example, a display area, and a program name corresponding to each key can be displayed on the display area of the key, and in addition, a virtual key is also displayed on the human-computer interaction interface of the display screen of the video console, so that a user can directly see a playing program that has been saved by the media server 1 on the display frame of the virtual key, for example, the display screen.
In addition, after the video console finishes making the playing scene, the playing program corresponding to the media server can be bound with the playing scene for storage, so that the playing scene can be directly loaded when the corresponding program is played. When the video console is shut down and restarted, the binding relationship between the playing program of each media server and the key still exists.
After the binding is completed, for example, at this time, it is necessary to control the playing program displayed by the media server 1 to be switched to the program 2 for playing, then the user may press a key corresponding to the program 2, for example, the key 2, at this time, the video console integrates the relevant information of the playing program corresponding to the key 2 to generate a program switching instruction, then the user pushes a control lever, or presses a determination key, for example, so that the program switching instruction is sent to the media server 1, and the media server 1 receives the program switching instruction to automatically switch the currently playing program to the program 2, thereby completing the seamless switching of the playing program.
In summary, the multi-device control method disclosed in the embodiment of the present invention realizes that a plurality of external devices can be controlled and managed by only one operator controlling the video console, so as to improve the operation precision, reduce the operation difficulty, reduce the labor cost, and achieve high stability and independent systems for the video console and the current control device; data interaction is carried out between the video console and the external equipment through the data exchange equipment, so that the field deployment difficulty is reduced; the expansion difficulty of the external equipment is reduced, and the expansion of the equipment is facilitated.
