Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. In the following description, numerous specific details are provided to give a thorough understanding of example embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, steps, and so forth.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.

FIG. 1 shows a schematic diagram of a system architecture applied in accordance with an embodiment of the present disclosure. The system architecture comprises at least one user terminal 1, a server 2 in wireless communication connection with the user terminal 1, and at least one device to be projected 3 connected with the user terminal 1.

The user terminal 1 may be one of a smart phone, a tablet computer, and a portable computer, and the user terminal 1 may perform screen projection control on at least one device to be projected 3 in the same lan as the user terminal 1 based on a protocol (DLNA) specified by the Digital home Network Alliance. The device 3 to be projected can be an electronic display device for outputting images, such as a smart television, and the device 3 to be projected can further include a network television box connected with the smart television, data interaction is performed between the user terminal 1 and the network television box, so that screen projection control of the smart television is realized, and the user terminal 1 can specifically perform data interaction between the screen projection application and the network television box.

The server 2 has a software-oriented server and a hardware-oriented server. From the viewpoint of hardware, the server 2 is a physically present server, and may be a server constituted by one physical computer or a cluster server constituted by a plurality of physical computers. From the software perspective, a server refers to computer software with server-side functions and running server-side software. It may be a virtual server that occupies only a part of one computer, or may be a virtual cluster server that occupies a part or all of a plurality of computers, respectively. Particularly in a cloud environment, the application of the virtual cluster server is common. Thus, the overall system architecture can be viewed as being constructed from numerous nodes and connecting channels. In terms of "hardware", the architecture is built up from a myriad of hardware servers and other digital computing device terminals (such as the network television 1, etc.) and intermediate connection devices (such as network cables, routers, etc.). In terms of "soft", the framework is constructed from numerous running server-side software and client-side software (e.g., applications on the user terminal 1) and their interconnections. The server 2 receives the identification information of the screen device 3 to be projected, which is sent by the screen projecting application on the user terminal 1, and the server 2 determines an equipment description file corresponding to the identification information of the screen device 3 to be projected according to the identification information of the screen device 3 to be projected and the corresponding relation between the identification information and the equipment description file, and sends the equipment description file to the screen projecting application on the user terminal 1, so that the screen projecting application on the user terminal 1 can control the screen device 3 to be projected based on the equipment description file. As can be seen, according to the technical solution of the embodiment of the present invention, even when the device to be screen-projected 3 cannot recognize the request for acquiring the device description file sent by the user terminal 1 or the user terminal 1 cannot recognize the response information fed back by the device to be screen-projected 3 in response to the request for acquiring the device description file, the user terminal 1 may control the device to be screen-projected 3 according to the device description file acquired from the server 2, thereby effectively solving the problem that the device to be screen-projected 3 and the user terminal 1 cannot be screen-projected due to the fact that they cannot be adapted.

Some aspects of the embodiments of the present disclosure may be embodied based on a system architecture such as that shown in fig. 1 or variations thereof.

The embodiment of the disclosure provides a screen projection control method on a user terminal side and a screen projection control method on a server side.

Referring to fig. 2, fig. 2 is a flowchart illustrating a screen projection control method at a user terminal according to an example embodiment of the present disclosure, the screen projection control method being executed by a user terminal, the screen projection control method including:

and step S110, acquiring identification information of the device to be projected.

And step S120, sending the identification information of the device to be projected to a server.

Step S130, receiving an equipment description file from the server, where the equipment description file is determined by the server based on the identification information of the equipment to be screened and the corresponding relationship between the identification information and the equipment description file.

Step S140, controlling the device to be projected based on the device description file received from the server.

These steps are described in detail below.

In step S110, the identification information is used as characteristic information for identifying the identity of the device to be projected by the server or the user terminal, and the identification information may be Media Access Control Address (MAC) information of the device to be projected, a device number of the device to be projected, or a product model of the device to be projected. The MAC address information of the device to be screen-projected serves as the unique physical address information of the device to be screen-projected, the device number of the device to be screen-projected serves as the unique serial number of each produced device to be screen-projected by a manufacturer, and the identification information enables the server or the user terminal to identify the identity of the device to be screen-projected. It should be noted that the MAC address information is specifically a character string, and may be a 6-group 16-ary character string, for example, "00-0 a-0b-0c-0d-0 e".

When a user terminal controls a device to be screen-projected, an equipment description file of the device to be screen-projected needs to be acquired, and the user terminal can acquire the equipment description file for controlling the device to be screen-projected from a server, wherein the equipment description file contains all control information for screen projection control of the device to be screen-projected, the control information can include a control point address of each service on the device to be screen-projected, an action name of each service action and a parameter requirement of each service action, and services on the device to be screen-projected can include services such as video playing, pausing, control of playing progress, volume adjustment and the like. It should be noted that the device description file may specifically be an Extensible Markup Language (XML) file.

When a user terminal needs to call a certain service of a device to be screen-thrown, the user terminal and the device to be screen-thrown are connected in the same local area network, the user terminal sends service calling information containing action name information and parameter requirement information to a control point address corresponding to the service in the device to be screen-thrown, the device to be screen-thrown receives the service calling information sent by the user terminal, and executes corresponding service according to the action name information and the parameter requirement information in the service calling information, so that screen-throwing control of the device to be screen-thrown by the user terminal is realized.

When the user terminal acquires the device description file for controlling the screen device to be projected from the server, the identification information of the screen device to be projected can be acquired, the identification information of the screen device to be projected is sent to the server, and then the device description file for controlling the screen device to be projected is acquired from the server through the identification information of the screen device to be projected.

Referring to fig. 3, fig. 3 shows a flowchart of step S110 of a screen-projection control method at a user terminal side in an example embodiment of the present disclosure, and in this embodiment, step S110 may include the following steps:

step S1101, sending a request for obtaining identification information to the device to be projected.

Step S1102, receiving response information from the device to be screen-projected, the request for obtaining the identification information, and extracting the identification information of the device to be screen-projected from the response information.

In step S1101, when the user terminal needs to acquire the identification information of the device to be screen-projected, the user terminal may be connected to the same lan as the device to be screen-projected, and the user terminal sends a request for acquiring the identification information to the device to be screen-projected connected to the same lan. If the identification information is the equipment number of the equipment to be screen-projected or the product model of the equipment to be screen-projected, the request can be an acquisition request for acquiring the equipment information of the equipment to be screen-projected; if the identification information is MAC Address information, the request may be a request for acquiring MAC Address information specified in an Address Resolution Protocol (ARP).

In step S1102, when the identification information is the device number of the device to be screen-projected or the product model of the device to be screen-projected, after the device to be screen-projected receives an acquisition request of device information of the device to be screen-projected from the user terminal, the device to be screen-projected calls the device number of the device to be screen-projected or the product model of the device to be screen-projected from the factory configuration module in the local memory, adds the acquired device number of the device to be screen-projected or the product model of the device to be screen-projected to a response to the acquisition request of the device information of the device to be screen-projected, and sends the response to the user terminal, so that the user terminal acquires the device number of the device to be screen-projected or the product model of the device to be screen-projected.

If the identification information is the MAC address information, after the screen to be projected equipment receives a request for acquiring the MAC address information from the user terminal, the screen to be projected equipment checks the request to determine whether the request is a request for acquiring the MAC address information specified by an ARP protocol. And if the verification is successful, the device to be screen-projected acquires the MAC address information of the device to be screen-projected from the configuration information for storing the MAC address information. And the screen to be projected equipment adds the acquired MAC address information of the screen to be projected equipment to response information of the request for acquiring the MAC address information and sends the response information of the request for acquiring the MAC address information to the user terminal.

After receiving response information of a request for acquiring the MAC address information from the equipment to be screen-shot, the user terminal verifies the response information to determine whether the response information is the response information of the request for acquiring the MAC address specified by the ARP protocol, and if the verification is successful, the user terminal extracts the MAC address information of the equipment to be screen-shot from the response information. The MAC address information of the equipment to be projected is acquired by adopting an ARP protocol, the equipment to be projected can be realized only by the existing ARP protocol, and an additional communication mechanism is not required to be established.

In an embodiment, on the premise that the identification information of the device to be screen-projected is known, the identification information of the device to be screen-projected may be input by an entity button or a virtual control provided by the user terminal, so that the user terminal obtains the identification information of the device to be screen-projected.

Referring to fig. 2 again, in step S120, after the user terminal acquires the identification information of the device to be screen-projected, the user terminal may store the identification information of the device to be screen-projected, and send the acquired identification information of the device to be screen-projected to the server. The server is pre-stored with the corresponding relation between the identification information and the device description file, and can determine the device description file corresponding to the received identification information according to the identification information received from the user terminal and the corresponding relation between the identification information and the device description file pre-stored in the server, and further determine the device description file for controlling the screen projection device. And after determining to obtain the equipment description file corresponding to the received identification information, the server sends the determined equipment description file to the user terminal.

In step S130, the user terminal receives a device description file from the server, wherein the device description file is determined by the server based on the identification information of the device to be screened, which is received from the user terminal, and the corresponding relationship between the identification information and the device description file.

In step S140, after receiving the device description file from the server, the user terminal controls the device to be projected according to the device description file received from the server.

In an embodiment, if the device description file received from the server includes at least two device description files, the step S140 of controlling the device to be screened based on the device description file received from the server includes:

and controlling the equipment to be subjected to screen projection based on the equipment description file with the highest priority in the at least two equipment description files.

When the device description file received by the user terminal from the server comprises at least two device description files, the user terminal can control the device to be screened based on the device description file with the highest priority in the at least two device description files, and then the device description file with the highest priority is selected from the at least two device description files in order to control the screen-screened device.

It can be understood that, when the user terminal controls the screen-casting device through the device description file with the highest priority, if the user terminal does not monitor that the screen-casting device sends the response information of the screen-casting control information to the user terminal through the device description file with the highest priority, the user terminal may further select the device description file with the second highest priority to control the screen-casting device.

In an embodiment, the priorities of the at least two device profiles may be determined by the user terminal, or may be determined by the server, where after determining the priorities of the at least two device profiles, the server issues the determined priorities of the at least two device profiles to the user terminal.

In one embodiment, when determining the priority of at least two device description files, the user terminal may determine the priority of the device description file according to the data size of the device description file. Specifically, when the data size of the device description file is determined, the data size of the device description file can be determined by calculating all byte numbers in the device description file, and the smaller the data size of the device description file is, the higher the priority is; the larger the data amount of the device description file, the lower the priority. When the user terminal initiates control to the device to be projected by selecting the device description file with smaller data volume, the transmitted data volume can be effectively reduced, and further network resources can be saved.

In summary, by acquiring the identification information of the device to be screened by the user terminal, sending the identification information to the server, and by the server according to the identification information of the device to be screened, and the corresponding relation between the identification information and the device description file determines a device description file for controlling the device to be projected, and the determined device description file is sent to the user terminal, so that even when the device to be screen-shot cannot identify the request for acquiring the device description file sent by the terminal or the user terminal cannot identify the response information fed back by the device to be screen-shot aiming at the request for acquiring the device description file, the user terminal can also control the screen to be projected according to the device description file acquired from the server, so that the problem that the screen to be projected cannot be controlled due to the fact that the user terminal and the screen to be projected cannot be matched is effectively solved.

Referring to fig. 4, fig. 4 illustrates a flowchart of a screen-projection control method at a user terminal side according to an example embodiment of the present disclosure.

Before step S110 of acquiring identification information of a device to be projected, the method further includes:

step S105, sending an acquisition request for acquiring the device description file of the device to be projected to the device to be projected.

The step S110 of acquiring the identification information of the device to be projected includes:

step S1103, if the device description file of the device to be screen-projected fails to be obtained, obtaining the identification information of the device to be screen-projected.

In step S105, after the user terminal sends the request for obtaining the device description file of the device to be screen-projected to the device to be screen-projected, there may be a case that obtaining the device description file of the device to be screen-projected fails. When the user terminal determines that the device description file of the device to be screen-projected fails to be acquired, the user terminal cannot control screen projection of the device to be screen-projected.

In step S1103, when the user terminal fails to obtain the device description file of the device to be screen-projected, the user terminal may send a request for obtaining the identification information of the device to be screen-projected to the device to be screen-projected. If the identification information of the device to be screen-projected is the MAC address information of the device to be screen-projected, the request for obtaining the identification information of the device to be screen-projected may be a request for obtaining the MAC address information specified by the ARP protocol. The user terminal receives response information of the screen to be projected to a request for acquiring the MAC address information of the screen to be projected, extracts the MAC address information of the screen to be projected from the response information, and sends the MAC address of the screen to be projected to the server.

And if the identification information of the device to be screen-projected is the MAC address information of the device to be screen-projected, the corresponding relation between the identification information prestored in the server and the device description file is the corresponding relation between the MAC address information and the device description file. The server sends the determined equipment description file to the user terminal according to the MAC address information of the equipment to be screen-projected, which is received from the user terminal, and the equipment description file corresponding to the MAC address information of the equipment to be screen-projected, which is determined according to the corresponding relation between the MAC address information and the equipment description file. The user terminal performs screen projection control on the screen to be projected through the device description file received from the server, and the problem that screen projection control cannot be performed on the screen to be projected due to the fact that the user terminal and the screen to be projected cannot be matched is effectively solved.

Referring to fig. 5, fig. 5 is a flowchart illustrating a screen projection control method at a user terminal side in an exemplary embodiment of the present disclosure, and in an embodiment, after step S105 of sending an acquisition request for acquiring a device description file of the device to be screen projected to the device to be screen projected, the method further includes:

and step S106, monitoring response information of the screen to be projected to the acquisition request in a preset time period after the acquisition request is sent.

Step S107, if the device description file of the device to be screen-projected fed back by the device to be screen-projected according to the acquisition request is not monitored in the preset time period, failing to acquire the device description file of the device to be screen-projected.

In step S106, when the user terminal sends the request for obtaining the device description file of the device to be screen-projected to the device to be screen-projected, the device to be screen-projected cannot recognize the request sent by the user terminal, and when the device to be screen-projected cannot recognize the request sent by the user terminal, the device to be screen-projected cannot feed back the device description file of the device to be screen-projected to the user terminal. After sending an acquisition request for acquiring the device description file of the device to be projected to the device to be projected, the user terminal can monitor whether the device description file of the device to be projected, which is fed back by the device to be projected according to the acquisition request, is received within a preset time period, and then timely confirm whether the device to be projected feeds back the device description file.

In step S107, if the user terminal does not monitor the device description file of the to-be-screen-projected device fed back by the to-be-screen-projected device in response to the acquisition request within the preset time period, the user terminal may timely confirm that the device description file is not fed back by the to-be-screen-projected device, and thus the user terminal determines that acquiring the device description file of the to-be-screen-projected device fails. The method comprises the steps that after a user terminal sends an obtaining request for obtaining the device description file of the device to be projected to the device to be projected, whether the device to be projected feeds back the device description file or not is monitored, and whether the device to be projected feeds back the device description file or not can be quickly and effectively confirmed by the user terminal.

Referring to fig. 6, fig. 6 shows a flowchart of a screen projection control method at a user terminal side in an example embodiment of the present disclosure, and in an embodiment, after step S105 of sending an acquisition request for acquiring a device description file of the device to be screen projected to the device to be screen projected, the method further includes:

step S108, if it is monitored that the device to be screen-projected device feeds back the device description file of the device to be screen-projected according to the acquisition request within a preset time period after the acquisition request is sent, but the device description file cannot be identified, the device description file of the device to be screen-projected fails to be acquired.

In step S108, after the user terminal sends an obtaining request for obtaining the device description file of the device to be screen-projected to the device to be screen-projected, if the device to be screen-projected recognizes the obtaining request, the device to be screen-projected feeds back the device description file of the device to be screen-projected to the user terminal according to the obtaining request. Although the user terminal receives the device description file of the device to be screened, which is fed back by the device to be screened, the user terminal may be unable to identify that the device description file fed back by the device to be screened is the device description file for controlling the device to be screened, for example, a screen-casting application on the user terminal has a software version that is not the latest software version, so that the user terminal may be unable to identify that the device description file fed back by the device to be screened is the device description file for controlling the device to be screened. When the user terminal monitors the device description file of the to-be-projected device fed back by the to-be-projected device according to the acquisition request within a preset time period after the user terminal sends the acquisition request, but the device description file fed back by the to-be-projected device cannot be identified as the device description file for controlling the to-be-projected device, the user terminal determines that the device description file of the to-be-projected device fails to be acquired.

Referring to fig. 7, fig. 7 is a flowchart illustrating a screen-projection control method at a user terminal side according to an exemplary embodiment of the present disclosure, after step S105 of sending an acquisition request for acquiring a device description file of the device to be screen-projected to the device to be screen-projected, the method further includes:

step S109, if it is monitored that the screen to be projected has the device description file of the screen to be projected fed back by the screen to be projected to the screen to be projected which is fed back by the acquisition request within a preset time period after the acquisition request is sent, and the device description file can be identified, controlling the screen to be projected according to the device description file which is fed back by the screen to be projected.

After the user terminal sends an acquisition request for acquiring the device description file of the device to be screen-projected to the device to be screen-projected, if the device description file of the device to be screen-projected, which is fed back by the device to be screen-projected to the acquisition request, is monitored within a preset time period after the acquisition request is sent and the device description file can be identified, the user terminal confirms that the acquisition of the device description file of the device to be screen-projected is successful, and the user terminal can directly control the device to be screen-projected through the identified device description file.

Referring to fig. 8, fig. 8 is a flowchart illustrating a screen projection control method at a user terminal side in an exemplary embodiment of the present disclosure, and in this embodiment, after step S105 of sending an acquisition request for acquiring a device description file of the device to be screen projected to the device to be screen projected, the method further includes:

step S150, if the device description file of the to-be-projected device fed back by the to-be-projected device to the acquisition request is monitored within a preset time period after the acquisition request is sent, and the device description file can be identified, uploading the identification information of the to-be-projected device and the device description file fed back by the to-be-projected device to the server, so that the server establishes a corresponding relationship between the identification information and the device description file.

In step S150, the user terminal monitors the device description file of the device to be projected, which is fed back to the acquisition request by the device to be projected, within a preset time period after the acquisition request is sent, and can identify the device description file. The user terminal can directly control the device to be projected through the identified device description file. It should be noted that, after the identification information obtained by the user terminal from the device to be screen-projected, the user terminal may also upload the identification information obtained from the device to be screen-projected and the device description file fed back by the device to be screen-projected to the server, so that the server establishes a corresponding relationship between the identification information and the device description file.

Referring to fig. 9, fig. 9 is a flowchart illustrating a server-side screen projection control method according to an exemplary embodiment of the present disclosure, the screen projection control method being executed by a server, the server-side screen projection control method including:

step S210, receiving the identification information of the device to be projected, which is sent by the user terminal.

Step S220, determining an equipment description file corresponding to the identification information of the equipment to be screen-projected according to the identification information of the equipment to be screen-projected and the corresponding relation between the identification information and the equipment description file.

Step S230, sending the device description file to the user terminal, so that the user terminal controls the device to be projected based on the device description file.

In step S210, the server receives identification information of the device to be screen-projected, which is sent by the user terminal, where the identification information is used as feature information for identifying the identity of the device to be screen-projected by the server or the user terminal, and the identification information may be information such as MAC address information or device number.

In step S220, since the server pre-stores the corresponding relationship between the identification information and the device description file, the server may determine the device description file corresponding to the received identification information according to the identification information received from the user terminal and the corresponding relationship between the identification information and the device description file pre-stored in the server, and further determine the device description file for controlling the device to be screen-projected.

In one embodiment, if the identification information of the device to be screen-projected is the device number of the device to be screen-projected, the correspondence between the identification information prestored in the server and the device description file is the correspondence between the device number of the device to be screen-projected and the device description file corresponding to the device to be screen-projected. For the device number of the device to be screen-projected, which is received from the user terminal, the server can quickly and accurately determine the device description file for controlling the device to be screen-projected, which corresponds to the device number, based on the corresponding relationship between the device number and the device description file. And the server sends the determined equipment description file to the user terminal, so that the user terminal can control the screen to be projected according to the equipment description file received from the server.

In an embodiment, if the identification information of the device to be screen-projected is the product model of the device to be screen-projected, the corresponding relationship between the identification information and the device description file prestored in the server is the corresponding relationship between the product model of the device to be screen-projected and the device description file corresponding to the device to be screen-projected, and for the product model of the device to be screen-projected received from the user terminal, the server may still determine the device description file for controlling the device to be screen-projected of the product model based on the corresponding relationship between the product model and the device description file. In the screen-to-be-projected equipment with the same product model produced by each manufacturer, the corresponding equipment description files in the screen-to-be-projected equipment are consistent, so that the screen-to-be-projected equipment with the same product model can be classified into the same category according to the product model of the screen-to-be-projected equipment, and the corresponding relation between the screen-to-be-projected equipment in the same category and the equipment description file is established.

In one embodiment, if the identification information of the device to be screen-projected is the MAC address information of the device to be screen-projected, the correspondence between the identification information prestored in the server and the device description file is a one-to-one correspondence between the MAC address information of the device to be screen-projected and the device description file corresponding to the device to be screen-projected. The server can accurately determine the device description file for controlling the device to be screen-projected for the MAC address information of a certain device to be screen-projected received from the user terminal by pre-storing the corresponding relation between the MAC address information and the device description file. And the server sends the determined equipment description file to the user terminal, so that the user terminal can control the screen to be projected according to the equipment description file received from the server.

Referring to fig. 10, fig. 10 is a flowchart illustrating a screen projection control method on a server side according to an example embodiment of the present disclosure, in this embodiment, a correspondence between the identification information and the device description file includes a correspondence between feature information of the identification information and the device description file, where the screen projection control method on the server side further includes:

step S310, obtaining the identification information and the device description file of at least two devices to be projected.

Step S320, determining the devices to be projected which are associated with each other according to the device description files of the at least two devices to be projected.

And step S330, performing XOR comparison on the identification information corresponding to the correlated equipment to be projected, and determining to obtain the characteristic information of the identification information.

Step S340, correspondingly storing the characteristic information of the identification information and the device description file of the device to be projected, which are associated with each other, and generating a corresponding relationship between the characteristic information of the identification information and the device description file.

In step S310, in this embodiment, it is described by taking the identification information as the MAC address information as an example, and the preset correspondence between the identification information and the device description file may be a correspondence between feature information of the MAC address information and the device description file, that is, a correspondence between a part of information in the MAC address information and the device description file. When the server establishes the corresponding relationship between the characteristic information of the MAC address information and the device description file, the MAC address information and the device description file of at least two devices to be projected need to be acquired, so as to generate the corresponding relationship between the characteristic information of the MAC address information and the device description file.

In one embodiment, the acquiring identification information and device description files of at least two devices to be projected S310 includes:

and receiving the identification information of at least two devices to be projected and the device description file uploaded by the user terminal.

If the identification information of the device to be screen-projected is the MAC address information of the device to be screen-projected, the MAC address information and the device description file of at least two devices to be screen-projected, which are acquired by the server, can also be uploaded by the user terminals, wherein the MAC address information and the device description file of the device to be screen-projected can be uploaded by one or more user terminals, and for each user terminal, the MAC address information and the device description file of one or more devices to be screen-projected can be simultaneously uploaded to the server each time.

Certainly, the obtained MAC address information and device description files of the at least two devices to be screen-projected may also be preconfigured in the server, for example, a manager of the server obtains the MAC address information and the device description file of the existing device to be screen-projected from the market, and uploads the obtained MAC address information and the device description file of the device to be screen-projected to the server, so that the server obtains the MAC address information and the device description file of the device to be screen-projected.

With continued reference to fig. 10, in step S320, when the device to be screened is a device of a certain model manufactured by the same manufacturer, the information in the device description file of the device to be screened is consistent. Therefore, the acquired at least two pieces of screen projection equipment can be classified according to the information in the equipment description file, when the information in the equipment description file is consistent, the pieces of screen projection equipment corresponding to the equipment description file with consistent information are used as a class and are determined as the pieces of screen projection equipment which are mutually associated, and then the MAC address information corresponding to the pieces of screen projection equipment which are mutually associated is conveniently analyzed so as to determine the common characteristic information of the MAC address information of the pieces of screen projection equipment which are mutually associated.

Referring to fig. 11, fig. 11 is a flowchart illustrating a step S320 of a screen projection control method on a server side according to an exemplary embodiment of the present disclosure, in this embodiment, the step S320 of determining identification information associated with each other according to device description files of the at least two devices to be screen projected includes the following steps:

step S3201, formatting the device description files corresponding to the at least two screen projection devices to obtain at least two formatted data;

step S3202, comparing the structure of the formatted data, and comparing the node value of the formatted data;

step S3203, the devices to be projected corresponding to the formatted data with consistent structures and consistent node values are determined as the devices to be projected which are associated with each other.

In step S3201, the embodiment continues to use the identification information as the MAC address information for example, because the device description file of the device to be screened is generally an XML file, when determining whether the XML file is a consistent XML file, the XML file may be formatted to obtain corresponding formatted data, and whether the information in the two device description files is consistent is determined based on the feature information included in the formatted data, such as the feature information of the structure and the node value.

In step S3202, for all the obtained formatted data, the server compares whether the structures in all the formatted data are consistent and compares whether the node values in the formatted data are consistent. When the structures in the two formatted data are consistent and the node values are consistent, the information in the two device description files corresponding to the two formatted data are consistent; when the structures in the two formatted data are consistent but the node values are not consistent, the node values in the two formatted data are not consistent but the structures are consistent, or the structure node values in the two formatted data are not consistent and the structures are not consistent, the information in the two device description files corresponding to the two formatted data are not consistent.

In step S3203, the devices to be screen-projected corresponding to the formatted data with the same structure and the same node value are determined as the devices to be screen-projected which are associated with each other, so as to facilitate analysis and processing of the MAC address information of the devices to be screen-projected which are associated with each other, so as to determine common characteristic information of the MAC address information of the devices to be screen-projected which are associated with each other.

Still referring to fig. 10, in step S330, for the MAC address information of the devices to be screened, which are associated with each other, the server compares the MAC address information of the devices to be screened, which are associated with each other, to determine the characteristic information of the MAC address information of the devices to be screened, which is associated with each other. Specifically, the character strings corresponding to the MAC address information of the devices to be projected that are associated with each other may be subjected to xor comparison to determine the characteristic information included in the MAC address information.

For example, when the correlated device to be projected includes three pieces of MAC address information, the corresponding three pieces of MAC address information are "0 f-1a-f0-0 a-ac-bc", "0 f-1 b-11-22-33-54" and "0 f-1 c-66-77-88-99", respectively, the characters at each position in the three pieces of MAC address information are subjected to xor comparison, and the xor result is "000111111111". In the xor result, "0" indicates that the characters at the corresponding positions in the MAC address information are the same, and "1" indicates that the characters at the corresponding positions in the MAC address information are different, so that it can be determined that the three pieces of MAC address information have the same characters at the first to third positions, respectively, and the diagnostic information of the corresponding three pieces of MAC address information is "af 1".

In step S340, the server stores the characteristic information of the MAC address information in association with the device description file corresponding to the characteristic information of the MAC address information, and generates a correspondence between the characteristic information of the MAC address information and the device description file. It should be noted that, because the feature information of the MAC address information is the same feature information that two or more pieces of MAC address information have at the same time, in the correspondence relationship between the feature information of the MAC address information and the device profile, the feature information of the MAC address information is stored in correspondence with two or more device profiles.

By setting the corresponding relation between the characteristic information of the MAC address information and the device description file, the server can accurately determine the device description file for controlling the device to be projected, which is received from the user terminal. In addition, compared with the one-to-one correspondence relationship formed by the MAC address information of each device to be screened and the device description file corresponding to the device to be screened, the method does not need to store the MAC address information of each device to be screened, and further can reduce the data volume of the server for storing the MAC address information, so that the storage resources in the server are saved.

In an embodiment, the correspondence between the feature information of the identification information and the device description file may be a mapping table formed between the feature information of the identification information and the corresponding device description file, or may be a data set formed between the feature information of the identification information and the corresponding device description file.

Referring to fig. 12, fig. 12 is a flowchart illustrating a screen projection control method on a server side according to an exemplary embodiment of the present disclosure, where the screen projection control method in this embodiment further includes:

step S240, determining the priority of at least two device description files.

Step S250, sending the priorities of at least two device description files to the user equipment.

In step S240, as can be seen from the foregoing description, when the server determines that the device description file corresponding to the identification information of the device to be screen-projected is obtained according to the identification information of the device to be screen-projected received from the user terminal and the correspondence between the identification information and the device description file, at least two determined device description files may be provided. For the plurality of determined device description files, in order to enable the user terminal to better control the device to be screened from the device description file received from the server, the server may determine the priority of at least two device description files required to be sent to the user terminal.

In one embodiment, when determining the priority of at least two device description files required to be sent to the user terminal, the server may determine the priority of the device description file according to the data size of the device description file. Specifically, when the data size of the device description file is determined, the data size of the device description file can be determined by calculating all byte numbers in the device description file, and the smaller the data size of the device description file is, the higher the priority is; the larger the data amount of the device description file, the lower the priority.

In step S250, the server sends the priorities of the at least two device description files to the user terminal, so that the user terminal can select a device description file with the highest priority from the multiple device description files according to the priorities to control the device to be screened, and further, the user terminal can select a suitable device description file from the at least two device description files in order to control the device to be screened.

In order to display the interaction relationship between the user terminal and the server, referring to fig. 13, fig. 13 is a flowchart illustrating the interaction between the user terminal and the server based on the screen projection control method according to an exemplary embodiment of the present disclosure, and steps of the user terminal side and the server side are embodied in the flowchart of fig. 13.
