The processing device and the mobile terminal are two different devices, and the processing device may include a mobile device such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, a pedometer, and a fixed device such as a Digital TV, a desktop computer, and the like, which is not limited in the embodiments of the present application.

And S102, the processing equipment establishes screen projection connection with the N mobile terminals, distributes equipment numbers for the N mobile terminals, and sends the equipment numbers of the N mobile terminals to the corresponding mobile terminals.

In the embodiment of the application, since the processing device receives N screen-casting requests sent by N mobile terminals, the processing device may establish screen-casting connection with the N mobile terminals, allocate device numbers to the N mobile terminals, and send the device numbers of the N mobile terminals to corresponding mobile terminals, and optionally, one mobile terminal corresponds to one device number. The device number is used for uniquely indicating each mobile terminal, and may be, for example, a sequence number for successfully establishing screen-casting connection between the N mobile terminals and the processing device; or the processing device may randomly generate different N device numbers, and send the N device numbers to the corresponding mobile terminals, where the device number of each mobile terminal is different. For example, N is equal to 4, and 4 device numbers are 1, 2, 3, and 4, respectively, then the device numbers may be assigned to the 4 mobile terminals according to the time sequence of successful screen projection connection establishment between the 4 mobile terminals and the processing device. For example, the 4 mobile terminals are a1, a2, a3 and a4, respectively, and the time sequence of successful screen projection connection establishment between the 4 mobile terminals and the processing device is as follows: a1> a2> a3> a4, the device number of mobile terminal a1 may be 1, the device number of mobile terminal a2 may be 2, the device number of mobile terminal a3 may be 3, and the device number of mobile terminal a4 may be 4. Alternatively, the processing device may randomly acquire 4 different device numbers and randomly allocate the device numbers to the 4 mobile terminals, as long as the device numbers of the 4 mobile terminals are different.

The processing equipment sends the equipment numbers of the N mobile terminals to the corresponding mobile terminals, namely, each equipment number is marked, when the subsequent mobile terminals send screen projection data packets to the processing equipment, the processing equipment can determine which screen projection data packet sent by the mobile terminal is the screen projection data packet according to the equipment number in the screen projection data packet when receiving the screen projection data packet, namely, the mobile terminals which specifically send the screen projection data packet are distinguished according to the marks, so that the data in the screen projection data packet is determined to be output in the corresponding screen projection area of the processing equipment, the data collision of the N mobile terminals output during screen projection can be avoided, and the screen projection accuracy is improved.

Optionally, the processing device may sequentially establish screen-casting connections with the N mobile terminals. Optionally, the processing device sends a message of successfully establishing screen-casting connection to a first mobile terminal in the N mobile terminals; the processing equipment receives the number of the mobile terminals allowing screen projection, which are sent by the first mobile terminal; and if the N is less than or equal to the number of the mobile terminals allowing screen projection, the processing equipment establishes screen projection connection with the rest N-1 mobile terminals in the N mobile terminals. Optionally, the message of successfully establishing the screen-casting connection is used to indicate that the first mobile terminal and the processing device successfully establish the screen-casting connection, where the first mobile terminal is a mobile terminal in which the first of the N mobile terminals and the processing device successfully establish the screen-casting connection.

Optionally, after the processing device and the mobile terminal successfully establish the screen-casting connection, the processing device may send a message that the screen-casting connection is successfully established to the mobile terminal. When a first mobile terminal of the N mobile terminals receives a message of successfully establishing screen projection connection sent by the processing device, it may be indicated that the first mobile terminal and the processing device successfully establish screen projection connection, and then the first mobile terminal may send the number of mobile terminals allowed to project screens to the processing device, that is, the number of mobile terminals allowed to project screens is selected by the first mobile terminal. Optionally, the number of screens projected by the mobile terminal allowed to project may also be determined by the processing device, which is not limited in this embodiment of the application.

It can be seen from the above that N is the number of mobile terminals that need to establish screen projection connection with the processing device, and if N is less than or equal to the number of mobile terminals that allow screen projection, each of the N mobile terminals can establish screen projection connection with the processing device, and in this case, the processing device establishes screen projection connection with the remaining N-1 mobile terminals of the N mobile terminals. That is, after the processing device establishes the screen-casting connection with the first mobile terminal, the first mobile terminal sends the number of the mobile terminals allowed to cast the screen to the processing device. And if the N is less than or equal to the number of the mobile terminals allowed to screen, the screen-casting connection is established between the processing equipment and the remaining N-1 mobile terminals in the N mobile terminals, which indicates that the remaining N-1 mobile terminals are not in screen-casting connection with the processing equipment. Optionally, when the processing device establishes the screen-casting connection with any one of the N mobile terminals, the other mobile terminals in the N mobile terminals may output waiting information, and the waiting information may indicate the number of mobile terminals that need to be connected with the processing device and the number of mobile terminals that have not currently established the screen-casting connection with the mobile terminal. Through outputting the waiting information, the screen projection connection condition between the mobile terminal and the processing equipment can be more intuitively known.

Optionally, if N is greater than the number of the mobile terminals allowed to screen, which is sent by the first mobile terminal, and indicates that all of the N mobile terminals cannot be connected to the processing device, the number of the mobile terminals equal to the number of the mobile terminals allowed to screen may be selected from the N mobile terminals, and the connection with the processing device may be established. For example, the number of mobile terminals equal to the number of mobile terminals allowed to screen may be selected according to the time when the N mobile terminals send the screen-casting request, or the connection with the processing device may be established by receiving information such as device parameters of the mobile terminals allowed to screen, which is sent by the first mobile terminal. That is, when N is greater than the number of the mobile terminals allowed to screen, the first mobile terminal may select the number of the mobile terminals equal to the number of the mobile terminals allowed to screen among the N mobile terminals to screen. Because the first mobile terminal can select the number of the mobile terminals allowed to screen or the equipment parameters of the mobile terminals allowed to screen, the screen can be projected more flexibly, and the user experience is improved.

S103, the processing equipment divides the screen projection area of the processing equipment to obtain N output areas.

In the embodiment of the application, the processing device can divide the screen projection areas of the processing device according to the number of the mobile terminals which successfully establish the screen projection connection to obtain N output areas. Optionally, the processing device may further establish a correspondence between the N output areas and the device numbers of the N mobile terminals, where one output area corresponds to one device number. That is, the first mobile terminal may select the number of mobile terminals allowed to screen, but the final division of the screen projection area is determined according to the number of mobile terminals successfully establishing the screen projection connection. In the embodiment of the application, the number of the mobile terminals allowing screen projection selected by the first mobile terminal is N, and a screen projection connection is successfully established between each of the N mobile terminals and the processing device. If the number of the mobile terminals which are selected by the first mobile terminal and allowed to screen is N, and only part of the N mobile terminals successfully establish screen-casting connection with the processing equipment, the processing equipment can screen-cast the mobile terminals which successfully establish screen-casting connection with the processing equipment. Or, the processing device may also receive a connection reestablishment request sent by the first mobile terminal, and establish a connection with the N-1 mobile terminals according to the connection reestablishment request, thereby performing screen projection.

Optionally, when the screen projection connection is successfully established between the N mobile terminals and the processing device, the processing device may divide the screen projection area of the processing device according to the number N of the successfully connected mobile terminals to obtain N output areas, that is, the processing device divides the screen projection area into N output areas. By establishing a corresponding relation between the N output areas and the equipment numbers of the N mobile terminals, one output area corresponds to one equipment number, the equipment numbers corresponding to the output areas are different, namely, each mobile terminal corresponds to one output area, and when a screen projection data packet is sent to a processing device by a subsequent mobile terminal, the output area in which data in the screen projection data packet is output is determined by acquiring the equipment number in the screen projection data packet. Optionally, the output area may include a size and a start position coordinate, that is, one output area may be determined by the size and the start position coordinate, for example, the output area may be expressed by the size and the start position coordinate, a correspondence between the size and the start position coordinate of each output area in the N output areas and the device numbers of the N mobile terminals may be established, when a screen projection data packet is subsequently received, the device number in the screen projection data packet may be determined, and the size and the start position coordinate corresponding to the device number are determined according to the correspondence, so that data in the screen projection data packet is output in an area corresponding to the size and the start position coordinate in the screen projection area.

Optionally, the mode that the processing device divides the screen projection area of the processing device to obtain N output areas may be that the screen projection area is equally divided by N to obtain N output areas with the same area. Referring to fig. 4, fig. 4 is a schematic page diagram of dividing a screen projection area provided in an embodiment of the present application, a screen projection area of a processing device is shown as 401a, the processing device divides the screen projection area into N equal parts, and obtains N output areas with the same area, as shown as 402a, where each output area in fig. 4 includes a device number of a terminal device (i.e., an upper left corner number of each output area), and optionally, the device number of the terminal device may not be output.

Optionally, the processing device may also not equally divide the screen projection area by N, so as to obtain N output areas with possibly unequal area. For example, the screen projection area may be divided into N output areas with unequal area, alternatively, N is equal to 4, the area of the output area 1 is larger than that of the output area 2, the area of the output area 2 is equal to that of the output area 3, and the area of the output area 3 is equal to that of the output area 4. Referring to fig. 4, a screen projection area of the processing device is shown as 401b, the processing device divides the screen projection area to obtain 4 output areas shown as 402b, and optionally, the area of the output area 1 is larger than the area of other output areas in the screen projection area.

Optionally, when the corresponding relationship between the N output areas and the device numbers of the N mobile terminals is subsequently established, the corresponding relationship between the device number of the first mobile terminal and the output area 1 may be established, the corresponding relationship between the device numbers of the N mobile terminals except the first mobile terminal and any one of the device numbers of the output area 2, the device number of the output area 3, and the device number of the output area 4 may be established, and finally, the corresponding relationship between the N output areas and the device numbers of the N mobile terminals is established, and one output area corresponds to the device number of one mobile terminal.

And S104, the processing equipment receives a screen projection data packet sent by the ith mobile terminal in the N mobile terminals successfully establishing the screen projection connection, determines the equipment number of the ith mobile terminal from the screen projection data packet, determines a target output area corresponding to the equipment number of the ith mobile terminal based on the corresponding relation, and outputs data in the screen projection data packet in the target output area.

In the embodiment of the application, because the N mobile terminals are all successfully connected with the processing device in a screen projection manner, the processing device can receive a screen projection data packet sent by the ith mobile terminal in the N mobile terminals, determine the device number of the ith mobile terminal from the screen projection data packet, determine a target output area corresponding to the device number of the ith mobile terminal based on the corresponding relationship, and output data in the screen projection data packet in the target output area. Optionally, the ith mobile terminal is any one of N mobile terminals, i is a positive integer less than or equal to N, and the screen projection data packet may include data and a device number. That is to say, for each of the N mobile terminals, when the processing device receives the screen projection data packet sent by the processing device, the processing device may determine the device number of the mobile terminal from the screen projection data packet, and further determine a target output area corresponding to the device number in the screen projection area, so as to output data in the screen projection data packet in the target output area, thereby implementing screen projection for each mobile terminal.

Optionally, when the mobile terminal sends data to the processing device for output, in order to avoid that the processing device cannot distinguish which output area of the screen projection area the data is output in, the mobile terminal may package the device number and the data of the mobile terminal to obtain a screen projection data packet, and send the screen projection data packet to the processing device. When receiving the screen projection data packet, the processing device can analyze the screen projection data packet, determine the device number in the screen projection data packet, thereby determining an output area, and output the data of the mobile terminal in the output area.

Optionally, the processing device may analyze the screen projection data packet to obtain a device number of the ith mobile terminal carried in the packet header of the screen projection data packet and data of the ith mobile terminal carried in the screen projection data packet; the processing device determines a target output area from the corresponding relation based on the device number of the ith mobile terminal, and outputs the data of the ith mobile terminal in the target output area. Data needing screen projection and the equipment number of the mobile terminal are packaged and then sent to the processing equipment, so that data loss in the data sending process can be avoided, and data incompleteness is caused. Optionally, the device number is obtained by analyzing the encapsulated data packet, so that the output area corresponding to the device number can be conveniently determined, the data of the mobile terminal is output in the output area corresponding to the device number, the data disorder of the N mobile terminals output in the output area is avoided, and the screen projection accuracy is improved.

Optionally, the data in the screen projection data packet may be output by a display interface, or may also be output by voice or other manners, which is not limited in this embodiment of the application. When the data in the screen-shot data packet is output in a display interface manner, the output area may refer to a display area, and optionally, the data in the screen-shot data packet may be output in a corresponding display area.

In the embodiment of the application, the screen projection connection between the processing equipment and the at least one mobile terminal is established, so that the at least one mobile terminal can be connected, the screen can be projected to the at least one mobile terminal, and the space of the processing equipment can be reasonably utilized. Optionally, in practical application, by projecting at least one mobile terminal to the processing device, for the mobile terminal, data output of each mobile terminal is not interfered with each other, so that the projection is richer; for a user, data of at least one mobile terminal can be checked at the same time, comparison is facilitated, and interestingness of screen projection of the terminal is improved.

Optionally, after the processing device outputs the data in the screen projection data packet in the target output area, that is, after the processing device projects the screen of the mobile terminal, the processing device may further control the mobile terminal, for example, may perform adjustment processing on the data in any one of the mobile terminals, so that the data of the mobile terminal output in the screen projection area is clearer. Referring to fig. 5, fig. 5 is a flow chart illustrating a processing method according to a second embodiment, as shown in fig. 5, the method includes, but is not limited to, the following steps:

s201, the processing device receives an information display request sent by the ith mobile terminal.

In the embodiment of the application, the processing device receives an information display request sent by an ith mobile terminal, and optionally, the information display request includes display data and/or indication information of the ith mobile terminal, and the indication information is used for switching a display size of a target output area corresponding to the ith mobile terminal. For example, when at least one mobile terminal is subjected to screen projection, display data, such as working data, learning data and the like, may be received by the ith mobile terminal of the at least one mobile terminal, but since the processing device performs screen projection on each of the at least one mobile terminal, in this case, when the display data received by the ith mobile terminal is output, the display data may not be conveniently viewed because the size of the output area is small. For example, when the processing device displays the display data in the output area in a page display manner, the display data is not convenient to view because the output area is small in size and is displayed in the output area directly, so that the size of the screen projection area can be adjusted to facilitate viewing of the display data. Optionally, after the display data is viewed, an information display ending request can be received, so that the output area is switched back to at least one output area, and the screen projection of at least one mobile terminal is continued.

S202, the processing equipment switches the display size of the target output area corresponding to the ith mobile terminal to a preset size according to the indication information, and/or outputs the display data of the ith mobile terminal to the target output area with the preset size.

In this embodiment of the application, the preset size may refer to a size that facilitates viewing of display data in the target output area. For example, the preset size may be the size of the screen projection area or other sizes, which is not limited in the embodiment of the present application. Optionally, when receiving the indication information, the processing device may determine an ith mobile terminal corresponding to the indication information, so as to switch a display size of a target output area corresponding to the ith mobile terminal to a preset size, and output display data of the ith mobile terminal in the target output area with the preset size.

Optionally, after receiving the information display request sent by the 1 st mobile terminal, the processing device switches the display size of the target output area corresponding to the 1 st mobile terminal to the preset size according to the indication information, and/or outputs the display data of the ith mobile terminal to a page in the target output area with the preset size as shown in 602. Optionally, the processing device may further receive an information display end request, thereby switching the output area back to at least one output area, and continuing to screen at least one mobile terminal as shown in 603. In fig. 6, the number in the output area corresponds to the mobile terminal, for example, the output area corresponding to the first mobile terminal is the output area 1, and the number may not be displayed in the output area in the page, which is only for convenience of description.

Optionally, the processing device may obtain data in any one of the N mobile terminals based on the processing device, and may implement data transmission between the mobile terminals. Optionally, the processing device receives a data acquisition request sent by the ith mobile terminal, and acquires a device parameter of the jth mobile terminal and a parameter of target data in the jth mobile terminal; and the processing equipment acquires target data corresponding to the parameters of the target data sent by the jth mobile terminal and sends the target data to the ith mobile terminal.

Optionally, the data obtaining request is used to request to obtain target data in a jth mobile terminal, where the ith mobile terminal and the jth mobile terminal are any two mobile terminals of the N mobile terminals, and j is a positive integer less than or equal to N. The parameter of the target data may include at least one of a name of the target data, an icon of the target data, a data number of the target data, or a storage path of the target data. That is to say, when the mobile terminal 1 needs to acquire the target data from the mobile terminal 2, the device parameters of the mobile terminal 2 and the parameters of the target data that needs to be acquired may be sent to the processing device, so that the processing device acquires the corresponding target data from the mobile terminal 2, and/or sends the target data to the mobile terminal 1, which may implement data transmission between mobile terminals, and may not need to disconnect the screen-casting connection and then connect with the mobile terminal that needs to acquire data, which may improve data transmission efficiency. In addition, the screen projection interaction between at least one mobile terminal can be realized by the method, and the interest of terminal screen projection is increased.

Referring to fig. 7, fig. 7 is a schematic page diagram of data transmission provided in an embodiment of the present application, optionally, N is equal to 4, and a page where the processing device receives screen-projected data packets sent by 4 mobile terminals and outputs data of the mobile terminals in corresponding output areas is shown as 701. Optionally, the processing device receives a data acquisition request sent by the mobile terminal 1, determines a device parameter of the mobile terminal 2 and a parameter of target data, the processing device acquires the target data corresponding to the parameter of the target data sent by the mobile terminal 2, and sends the target data to the mobile terminal 1, then the data of the output area corresponding to the mobile terminal 1 may be the same as the data of the output area corresponding to the mobile terminal 2, for example, a page of the mobile terminal 1 may be as shown in 702a, optionally, a page of the mobile terminal 2 may be as shown in 702b, a number in the output area corresponds to the mobile terminal, for example, the output area corresponding to a second mobile terminal is the output area 2, and no number may be displayed in the output area in the page, which is only for convenience of description.

Optionally, after the processing device outputs the data in the screen projection data packet in the target output area, that is, after the processing device projects the screen of at least one mobile terminal, the processing device may further receive a screen projection end instruction sent by the mobile terminal, and process the screen projection of the mobile terminal. Optionally, when a screen projection end instruction sent by a first mobile terminal of the N mobile terminals is received, the processing device disconnects the screen projection connection with each mobile terminal of the N mobile terminals. Optionally, the first mobile terminal is a mobile terminal in which a first one of the N mobile terminals successfully establishes a screen-casting connection with the processing device. That is, if the screen-casting ending instruction is sent by the first mobile terminal, the screen casting may be ended, that is, the screen casting connection with each of the N mobile terminals is disconnected.

Optionally, when a screen projection end instruction sent by a second mobile terminal of the N mobile terminals is received, the processing device disconnects the screen projection connection with the second mobile terminal, and/or maintains the screen projection connection with a mobile terminal different from the second mobile terminal of the N mobile terminals. That is, if the screen-projection completion instruction is sent by a second mobile terminal other than the first mobile terminal, the screen projection connection with the second mobile terminal may be disconnected only, the screen projection to the second mobile terminal may be completed, and the screen projection connection with a mobile terminal different from the second mobile terminal among the N mobile terminals may be maintained, that is, the screen projection to the mobile terminal other than the second mobile terminal may be continued.

In the embodiment of the application, since the first mobile terminal can select the number of the mobile terminals allowed to screen, for example, the first mobile terminal can be a mobile terminal used by a manager (such as a teacher or other managers), which is hereinafter referred to as a "management mobile terminal", and by screen-casting the management mobile terminal and a mobile terminal used by a plurality of members (such as students or other members), which is hereinafter referred to as a "member mobile terminal", data interaction between the management mobile terminal and the member mobile terminal can be realized. And when a screen projection ending instruction sent by the management mobile terminal is received, the screen projection is considered to be ended, and screen projection connection between the N mobile terminals is disconnected. When a screen projection ending instruction sent by a member mobile terminal is received, the member can be considered to have other things to be processed, under the condition, the screen projection connection between the member mobile terminal and the member mobile terminal can be only disconnected, the screen projection connection between processing equipment and other mobile terminals does not need to be disconnected, the screen projection can be ensured to be normal, and data can be normally output. Optionally, by determining the type of the mobile terminal sending the screen projection ending instruction, the screen projection terminal can be flexibly managed.

In the embodiment of the application, when at least one mobile terminal is projected, data in any one mobile terminal is adjusted, so that the data of the mobile terminal output in a screen projection area is clearer. Optionally, data transmission can be performed between the plurality of mobile terminals based on the processing device, and the mobile terminals which need to acquire data do not need to be connected with the mobile terminals to perform data transmission after the screen projection connection is disconnected, so that the data transmission efficiency can be improved. And, by determining the type of the mobile terminal sending the screen projection ending instruction, the screen projection terminal can be flexibly managed.
