[0047] It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0048] Referring to Figure 1 , Figure 1 is a structural schematic diagram of a screen projection control device of a hardware running environment related to the embodiment of the present application.

[0049] As Figure 1As shown, the screen projection control device can include a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize the connection and communication between the components. The user interface 1003 can include a display, an input unit such as a keyboard, and can also include a standard wired interface, a wireless interface. The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM) such as a disk memory. The memory 1005 can also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the screen projection control device, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0051] As Figure 1 As shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a screen projection control program.

[0052] In Figure 1 In the screen projection control device shown, the network interface 1004 is mainly used for data communication with the network integrated platform workstation; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the screen projection control device can be arranged in the screen projection control device. The screen projection control device calls the screen projection control program stored in the memory 1005 through the processor 1001, and executes the screen projection control method provided by the embodiment of the application.

[0053] Based on the above hardware structure, the screen projection control method embodiment of the application is proposed.

[0054] Referring to Figure 2 , Figure 2 The flowchart of the first embodiment of the screen projection control method of the application is shown.

[0055] In the first embodiment, the screen projection control method includes:

[0056] Step S10, obtaining the current network information of the target terminal device.

[0057] It should be noted that the execution subject of the embodiment is a screen projection control device, and can also be other devices that can achieve the same or similar functions, such as a smart television terminal, and the like. The embodiment is not limited thereto, and in the embodiment, the smart television terminal is taken as an example for description.

[0058] It should be understood that the current network information refers to network information of a target terminal device, and the current network information includes network address, subnet mask, gateway and the like of a network used by the target terminal device. The target terminal device is a computing service device with data processing, network communication and program running functions, such as a mobile phone, a tablet and the like. The embodiment is not limited thereto, and a mobile phone is taken as an example for description.

[0059] In step S20, when the current network information and the target network information are not in the same local area network, a peer-to-peer network strategy is used to establish a connection with the target terminal device.

[0060] It can be understood that the target network information refers to network information of a smart television terminal. Similarly, the target network information includes network address, subnet mask, gateway and the like of a network used by the smart television terminal. The smart television terminal can project the feedback content of the current terminal device. After obtaining the current network information and the target network information, it is determined whether the target terminal device and the smart television terminal are in the same local area network by using the network address and the subnet mask in the current network information and the network address and the subnet mask in the target network information.

[0061] It should be understood that the peer-to-peer network strategy refers to a network strategy for establishing near field communication between devices. The peer-to-peer network strategy is a P2P network connection strategy. Conventional network connection needs to ensure that the connected devices are in the same local area network. However, the devices connected by the peer-to-peer network strategy can not be in the same local area network, that is, the peer-to-peer network strategy can enable intranet devices in different local area networks to be directly connected.

[0062] In step S30, a control instruction sent by the target terminal device is received.

[0063] It should be understood that the control instruction refers to an instruction sent by the target terminal device for controlling the smart television terminal to project. After the smart television terminal and the target terminal device are successfully connected, the smart television terminal and the target terminal device can communicate and interact with each other, such as sending instructions, receiving feedback content and the like. That is, the smart television terminal receives the control instruction sent by the target terminal device.

[0064] In step S40, the content to be projected is projected by using the control instruction, so as to achieve control of projection based on the terminal device.

[0065] It can be understood that the to-be-screened content refers to the content that needs to be screened by the smart TV terminal, and the to-be-screened content is fed back to the smart TV terminal by the current terminal device, and the smart TV terminal screens the to-be-screened content after receiving the to-be-screened content.

[0066] Further, step S40 comprises: generating a corresponding counter-control instruction according to the control instruction; sending the counter-control instruction to the current terminal device, and receiving the to-be-screened content fed back by the current terminal device based on the counter-control instruction.

[0067] It should be understood that the counter-control instruction refers to an instruction used by the smart TV terminal to control the current terminal device in reverse, and the control instruction and the feedback instruction are in one-to-one correspondence, that is, the smart TV terminal generates a corresponding counter-control instruction based on the control instruction after receiving the control instruction, and sends the counter-control instruction to the current terminal device, and the current terminal device feeds back the to-be-screened content to the smart TV terminal based on the counter-control instruction after receiving the counter-control instruction, and the smart TV terminal screens the to-be-screened content through the control instruction, and the current terminal device can be a computing service device with data processing, network communication and program running functions, such as a notebook computer.

[0068] The embodiment realizes the control of the terminal device based on the screen by acquiring the current network information of the target terminal device, establishing a connection with the target terminal device through a peer-to-peer network strategy when the current network information and the target network information are not in the same local area network, receiving the control instruction sent by the target terminal device, and screening the to-be-screened content through the control instruction. Since the embodiment determines whether the target terminal device and the server are in the same local area network through the current network information and the target network information, if yes, a connection is established with the target terminal device through a peer-to-peer network strategy, and then the to-be-screened content is screened through the control instruction when the connection is successful, which can effectively improve the screen efficiency and realize the remote control of the terminal device.

[0069] In an embodiment, as Figure 3 The second embodiment of the screen control method is proposed based on the first embodiment, and step S20 comprises:

[0070] Step S201 determines the current network address and the current subnet mask of the target terminal device according to the current network information.

[0071] It should be understood that the current network address refers to the network address of the target terminal device connected to each other for communication, which can be an IP address, and the difference in physical address can be masked through the current network address, and the current subnet mask is used to divide the network address into network address and host address, and the current subnet mask is 32 bits.

[0072] In step S202, the target network address and the target subnet mask are determined according to the target network information.

[0073] It can be understood that the target network address refers to the network address of the smart TV terminal for mutual connection and communication. The target network address can be an IP address. The IP address of the smart TV terminal can be divided by the target subnet mask, i.e., the network address and the host address are determined.

[0074] Further, after step S202, the method further includes: when the current subnet mask is inconsistent with the target subnet mask, establishing a connection with the target terminal device through a peer-to-peer network strategy.

[0075] It should be understood that when it is determined that the current subnet mask is inconsistent with the target subnet mask, it indicates that the smart TV terminal and the target terminal device are not in the same local network. At this time, a connection can be established directly with the target terminal device through a peer-to-peer network strategy.

[0076] In step S203, when the current subnet mask is consistent with the target subnet mask, the current network address and the current subnet mask are calculated to obtain a current network value.

[0077] It should be understood that the current network value refers to a network value calculated by the network address and the subnet mask. After the target subnet mask of the smart TV terminal and the current subnet mask of the target terminal device are obtained, it is determined whether the target subnet mask and the current subnet mask are consistent. If so, the current network value of the target terminal device needs to be calculated. For example, the current subnet mask of the target terminal device is 255.255.255.0, and the target subnet mask of the smart TV terminal is 255.255.255.0. The current subnet mask is consistent with the target subnet mask, and the current network address is 192.168.0.101. That is, the current network value is 192.168.0.0&255.255.255.0=192.168.0.0. The specific calculation method is to convert the current network address and the current subnet mask into binary format.

[0078] In step S204, the target network address and the target subnet mask are calculated to obtain a target network value.

[0079] It can be understood that the target network value is calculated in the same way as the current network value, and is also calculated by the network address and the subnet mask, for example, the target network address is 192.168.100.5, and the target subnet mask is 255.255.255.0. The target network address and the target subnet mask are converted into binary format, and the target network value is 192.168.100.5&255.255.255.0=192.168.100.0. The specific calculation method is that 192.168.100.5 is converted into binary as 11000000101010000110010000000101, and 255.255.255.0 is converted into binary as 11111111111111111111111100000000.

[0080] Step S205, when the current network value and the target network value are inconsistent, the connection with the target terminal device is established through the peer-to-peer network strategy.

[0081] It should be understood that after obtaining the current network value and the target network value, it is determined whether the current network value and the target network value are consistent. If not, it indicates that the smart TV terminal and the target terminal device are not in the same local network, and at this time the connection with the target terminal device can be established through the peer-to-peer network strategy.

[0082] Further, before step S205, it also includes: sending the obtained preset starting instruction to the target terminal device, and receiving the starting success information of starting the target terminal application fed back by the target terminal device based on the preset starting instruction; determining the target terminal application address and the target terminal application name according to the starting success information; and generating the peer-to-peer network strategy according to the target terminal application address and the target terminal application name.

[0083] It can be understood that the target terminal application refers to the application installed in the target terminal device, which is the application required for using WIFI_Direct. The target terminal application also needs to be installed in the smart TV terminal. The smart TV terminal can broadcast its own state information through the target terminal application. The target terminal application address refers to the address of the target terminal application running in the target terminal device, and the target terminal application name refers to the name of the target terminal application in the target terminal device.

[0084] It should be understood that the preset starting instruction refers to the instruction for starting the target terminal application. After obtaining the preset starting instruction, the preset starting instruction is sent to the target terminal device to start the installed target terminal application, and the starting success information of starting the target terminal application is fed back to the smart TV terminal. The smart TV terminal generates the peer-to-peer network strategy through the target terminal application address and the target terminal application name.

[0085] The embodiment determines the current network address and the current subnet mask of the target terminal device through the current network information, and determines the target network address and the target subnet mask according to the target network information; then, it is judged whether the current subnet mask is consistent with the target subnet mask, if yes, the current network address, the current subnet mask, the target network address and the target subnet mask are calculated respectively to obtain the current network value and the target network value; then, it is further judged whether the current network value is consistent with the target network value, if not, it indicates that the target terminal device and the smart television terminal are not in the same local area network, at this time, the connection is established with the target terminal device through the peer-to-peer network strategy, so that the devices in different local area networks can be connected.

[0086] In an embodiment, as Figure 4 The third embodiment of the screen projection control method is provided based on the first embodiment, and before step S40, the method further includes:

[0087] Step S301: acquiring a current running state.

[0088] It can be understood that the current running state refers to the running state of the smart television terminal, and the running state includes a screen projection state and a non-screen projection state. The screen projection state refers to that the smart television terminal is performing screen projection. Of course, the non-screen projection state refers to that the smart television terminal is not performing screen projection at this time. The smart television terminal can be in a standby state or can be used for other functions.

[0089] Further, after step S301, the method further includes: when the current running state is the screen projection state, encapsulating the control instruction to obtain an HID control instruction.

[0090] The control instruction is used to project the content to be projected, including:

[0091] The HID control instruction is used to project the content to be projected.

[0092] It should be understood that the HID control instruction refers to a device control instruction, which includes a mouse control instruction, a keyboard control instruction, etc. When it is determined that the current running state is the screen projection state, it indicates that the smart television terminal is projecting at this time. At this time, the control instruction sent by the target terminal device needs to be encapsulated to obtain the HID control instruction, and then the HID control instruction is used to control the projection of the content to be projected.

[0093] Step S302: when the current running state is the non-screen projection state, the step of projecting the content to be projected by using the control instruction is performed.

[0094] It should be understood that after obtaining the current running state of the smart television end, it is necessary to determine whether the current running state is a non-screen projection state, and if so, the smart television end can directly screen the to-be-screened content fed back by the current terminal device.

[0095] The embodiment obtains the current running state, determines whether the current running state is a non-screen projection state, and performs the step of screening the to-be-screened content through the control instruction when the current running state is a non-screen projection state. Since the embodiment determines whether the current running state of the smart television end is a non-screen projection state after obtaining the current running state, if so, it indicates that the smart television end is not performing screen projection at this time, and the to-be-screened content is screened through the control instruction at this time, thereby improving the screen projection efficiency of the smart television end.

[0102] The control module 40 is configured to screen the to-be-screened content through the control instruction to realize the control of screen projection based on the terminal device.

[0103] The embodiment obtains current network information of a target terminal device; when the current network information and target network information are not in the same local area network, establishes a connection with the target terminal device through a peer-to-peer network strategy; receives a control instruction sent by the target terminal device; and performs screen projection on to-be-projected content through the control instruction, so as to realize control of screen projection based on a terminal device. Since the embodiment determines whether the target terminal device and the server are in the same local area network through the current network information and the target network information, if yes, a connection is established with the target terminal device through the peer-to-peer network strategy, and then when the connection is successful, the to-be-projected content is projected through the control instruction, which can effectively improve the screen projection efficiency and realize remote control of screen projection by the terminal device.
