[0032] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0033] In the existing screen projection technology, after the screen projection transmitter is connected to the corresponding screen projection receiver, the screen projection control is performed on the screen projection transmitter, and the content of the screen projection transmitter is projected to the screen projection receiver for display. Assuming that multiple screen projection transmitters need to perform screen projection operations, in the case of multiple screen projection transmitters, different screen projection transmitters need to be set up for projection respectively so that each screen projection transmitter can achieve its own screen projection purpose. However, the operation process is relatively cumbersome and complicated, and it is impossible to uniformly control and manage multiple screen projection transmitters, resulting in low screen projection efficiency.

[0034] In order to solve the above problems, this embodiment provides a screen projection method for unified control of multiple terminals. The executor of the method can be a server, or a cloud server, etc. This embodiment takes the server as an example to illustrate the screen projection method of this embodiment.

[0035] The server is connected to each first terminal, each second terminal and each screen projection receiving terminal respectively. The first terminal can be a mobile terminal such as a mobile phone, which is used to control each second terminal to perform screen projection operation control and management, and the second terminal is a screen projection sending terminal, which can be a mobile phone, tablet, PC, etc., and is used to project the screen content to the corresponding screen projection receiving terminal, and the screen projection receiving terminal is used to receive the screen projection content and display it.

[0036] like Figure 1 As shown, the screen projection method for unified control of multiple terminals executed by the server specifically includes the following steps:

[0037] Step S1: Obtain a device list in response to a screen projection request sent by the first terminal, and return the device list to the first terminal for the user to select a second terminal in the device list to be projected.

[0038] Combination Figure 2 As shown, after the user logs in to the specified software or the specified page on the first terminal, the user can send a screen projection request corresponding to the HTTP protocol to the server through his own first terminal. After receiving the screen projection request, the server generates a search instruction, calls a preset database according to the search instruction, and searches for all registered second terminals in the database; each second terminal will automatically write its own identification information into the database when registering and logging in for the first time, and detect the online or offline status of each second terminal in real time, and update the online or offline status in real time to the status information corresponding to each second terminal in the database.

[0039] During the search process, the second terminal that is registered and online in the database is marked as a second terminal that meets the screen projection conditions, and a device list is generated based on all second terminals that meet the screen projection conditions and their corresponding identification information.

[0040] The server returns the device list to the first terminal for display. The first terminal can generate a corresponding pop-up window or page to display the device list, so that the user can select the first terminal to be projected as the target device from the device list.

[0041] At the same time, when the server receives the screen projection request, the server can send a scan instruction to the first terminal, controlling the first terminal to use the mDNS or SSDP protocol to scan all screen projection receivers in the local area network; the first terminal can also automatically perform a scanning operation when issuing the screen projection request, that is, use the mDNS or SSDP protocol to scan all screen projection receivers in the local area network.

[0042] The first terminal generates a corresponding receiving terminal list for all the screen projection receiving terminals obtained by scanning, and displays the receiving terminal list on the interface provided by the first terminal for the user to select the screen projection receiving terminal to be projected.

[0043] The user selects the screen projection receiving end that needs to be projected on the first terminal, and marks the screen projection receiving end that needs to be projected as the target receiving end. At the same time, the first terminal records the identification information of the target receiving end to facilitate subsequent screen projection transmission.

[0044] Step S2: Obtain the user selection operation fed back by the first terminal, determine the target device from the device list based on the user selection operation, and generate a screen projection control instruction according to the user selection operation.

[0045] In addition to selecting the target receiving end on the first terminal, the user also selects the second terminal to be projected as the target device in the device list displayed on the first terminal. The first terminal receives the user's selection instruction and extracts the identification information of the target device.

[0046] In addition, the user can also select the projection content and projection mode on the first terminal, and the first terminal can directly generate the projection control instruction according to the identification information of the target device, the selected projection content and projection mode. In some embodiments, the user selection operation fed back by the first terminal can also be received by the server, and the server generates the projection control instruction according to the identification information, projection content and projection mode.

[0047] Among them, the projection content can be directly entered by the first terminal, that is, the user can download or store the projection content to be projected through the first terminal; in addition, the projection content can also be the storage resources on the second terminal, that is, each second terminal can upload its stored resources to the server in advance, and the server can display the storage resources corresponding to the target device for the user to select after determining the target device when displaying the device list. After selecting any second terminal as the target device, the user can check the storage resources corresponding to the target device as the projection content, so that when performing the projection operation later, the corresponding storage resources can be directly obtained from the server as the projection content for projection.

[0048] The screen projection mode refers to the method of displaying the projection content of the target device on the target receiving end, such as through wireless screen projection technology or wired screen projection technology to achieve the screen projection action.

[0049] Step S23: Control the first terminal to send a configuration instruction to the target receiving end, so that the target receiving end performs parameter configuration according to the configuration instruction to achieve screen projection connection between the target receiving end and the target device.

[0050] When the target receiving end is determined, the server controls the first terminal to send a configuration request to the target receiving end. After receiving the configuration request, the target receiving end returns its current configuration parameters to the first terminal, and the first terminal displays the current configuration parameters on the interface; the current configuration parameters include the resolution of the target receiving end and the display mode of the target receiving end, etc.; the display mode refers to the display settings or layout adopted after receiving the projection signal from the target device, and the mode will affect the display method of the projection content, including the aspect ratio, direction, size, etc. of the picture.

[0051] The user can modify the current configuration parameters of the target receiving end on the first terminal. The first terminal generates corresponding configuration instructions according to the user's configuration parameter adjustment operation. The first terminal directly sends the configuration instructions to the target receiving end, or the server forwards the configuration instructions generated by the first terminal to the target receiving end.

[0052] The target receiving end modifies its current configuration parameters according to the configuration instructions. At this time, the target receiving end applies the new configuration so that the display mode of the target receiving end matches the screen projection mode of the target device, so that the target receiving end can perfectly display the screen projection content sent by the target device.

[0053] Step S4: Send the screen projection control instruction to the target device, control the target device to parse the screen projection control instruction to obtain the projection content and transmit the projection content to the target receiving end, so that the target receiving end displays the projection content.

[0054] Assuming that the first terminal directly generates a screen projection control instruction according to the identification information of the target device, the selected screen projection content and the screen projection mode, the first terminal can send the generated screen projection control instruction to the server via an HTTP request.

[0055] The server parses the screen projection control instruction to determine the identification information of the target device contained in the screen projection control instruction, finds the corresponding target device through the identification information, and forwards the screen projection control instruction to the target device corresponding to the identification information through WebSocket or HTTP. After the target device receives the screen projection control instruction, it parses the screen projection control instruction to obtain the corresponding screen projection content.

[0056] The target device starts the corresponding screen projection program to transmit the projection content to the target receiving end to achieve the projection effect. The target device obtains its own projection execution status according to the execution log, and feeds back the projection execution status (success / failure) to the server through WebSocket or HTTP. After receiving the feedback projection status information, the server forwards the projection status information to the first terminal through WebSocket or HTTP. The first terminal displays the projection status information for the user to understand the projection status of this time.

[0057] In this embodiment, the target device to be projected can be selected from multiple second terminals that can perform screen projection sending operations through the first terminal. The target receiving end for screen projection reception can also be selected through the first terminal, and the target device can be controlled to start the corresponding screen projection program according to the screen projection control instruction to transmit the projection content to the target receiving end for screen projection display. Multiple second terminals can be centrally managed and controlled, and one first terminal can control different second terminals to perform their respective screen projection operations, simplifying the screen projection operation and improving the screen projection efficiency.

[0058] In some embodiments, a screen projection system with unified control of multiple terminals is also provided, the system includes a first terminal, a second terminal, a screen projection receiving terminal and a server, wherein the server executes the screen projection method with unified control of multiple terminals described in Example 1.
