The method includes: receiving a screen projection request from a screen projection terminal; displaying the screen projection information from the screen projection terminal based on a main display terminal in response to the screen projection request; and, in response to a synchronization display request sent by another terminal for synchronously displaying the screen projection information from the main display terminal, transmitting the screen projection information displayed by the main display terminal to the other terminal, so that the other terminal can read and display the screen projection information.

[0027] Figure 1The following schematically illustrates an exemplary system architecture 100 to which screen projection information synchronization can be applied according to an embodiment of the present disclosure. Figure 1 The examples shown are merely examples of system architectures to which the embodiments of the present disclosure may be applied, to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure may not be used in other devices, systems, environments or scenarios.

[0028] like Figure 1 As shown, the system architecture 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is used as a medium for providing a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 may include various connection types, such as wired and / or wireless communication links, etc.

[0029] The user may use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 via the network 104 to receive or send messages, etc. Various communication client applications may be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, and / or social platform software, etc. (only as examples).

[0030] The first terminal device 101 , the second terminal device 102 , and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0031] The server 105 may be a server that provides various services, such as a background management server (for example only) that supports websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process received user requests and other data, and feed back processing results (e.g., web pages, information, or data obtained or generated according to user requests) to the terminal devices.

[0032] It should be noted that the screen projection information synchronization method provided by the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the screen projection information synchronization device provided by the embodiment of the present disclosure can generally be set in the server 105. The screen projection information synchronization method provided by the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the screen projection information synchronization device provided by the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Alternatively, the screen projection information synchronization method provided by the embodiment of the present disclosure can also be executed by the first terminal device 101, the second terminal device 102 or the third terminal device 103, or can also be executed by other terminal devices different from the first terminal device 101, the second terminal device 102 or the third terminal device 103. Accordingly, the screen projection information synchronization device provided in the embodiment of the present disclosure can also be set in the first terminal device 101, the second terminal device 102 or the third terminal device 103, or in other terminal devices different from the first terminal device 101, the second terminal device 102 or the third terminal device 103.

[0033] For example, the main display terminal and the other terminals may originally be any one of the first terminal device 101, the second terminal device 102, or the third terminal device 103 (for example, the first terminal device 101, but not limited thereto), or may be other devices that have a communication connection with the first terminal device 101. Then, the first terminal device 101 may locally execute the screen projection information synchronization method provided in the embodiment of the present disclosure, or the screen projection information synchronization method provided in the embodiment of the present disclosure may be executed by other terminal devices, servers, or server clusters that have a communication connection with the first terminal device 101.

[0034] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0035] Figure 2 The flowchart of the method for synchronizing screen projection information based on the main display terminal according to an embodiment of the present disclosure is schematically shown.

[0036] like Figure 2 As shown, the method includes operations S201 to S203.

[0037] In operation S201, a screen projection request is received from a screen projection terminal.

[0038] According to an embodiment of the present disclosure, the screen projection end can represent any device or terminal that initiates screen projection and provides screen projection information to be projected.

[0039] In operation S202 , in response to the screen projection request, screen projection information from the screen projection end is displayed based on the main display end.

[0040] According to embodiments of the present disclosure, the primary display terminal can be a device or terminal with a display screen. A screen projection request is initiated by the projection terminal and sent to the primary display terminal, requesting that the projection information be displayed based on the primary display terminal. For example, in a conference room with a large screen, the primary display terminal can be the device or terminal corresponding to the large screen itself, or it can be a projector associated with the large screen, etc., without limitation herein.

[0041] In operation S203, in response to a synchronous display request sent by other terminals for synchronously displaying the projection information from the main display terminal, the projection information displayed by the main display terminal is sent to other terminals, so that the projection information is read and displayed based on the other terminals.

[0042] According to embodiments of the present disclosure, the other terminal may be a device or terminal with a display screen. A synchronous display request is initiated by the other terminal and sent to the main display terminal. The request may request a connection with the main display terminal or the projection terminal, and request that the projection information displayed by the main display terminal or the projection terminal be displayed on the other terminal that issued the synchronous display request.

[0043] According to the embodiments of the present disclosure, other terminals can also represent any terminals or devices that have established a connection with the main display terminal or the projection terminal. In this case, by sending a synchronous display request to the main display terminal or the projection terminal, the other terminal can directly request that the projection information displayed by the main display terminal or the projection information cast by the projection terminal be displayed on the other terminal that issued the synchronous display request.

[0044] According to the embodiments of the present disclosure, a large-screen application can be developed to work on the large-screen end, responsible for rendering the projection information and forwarding the projection information to other terminals.

[0045] For example, in a conference room with a large screen, the projection client is responsible for transmitting projection information to the large screen, which can then display the projection information simultaneously. Other terminals or devices, acting as other endpoints, can connect to the large screen via the network, receive the projection information forwarded by the large screen, and render and display it. Ultimately, projection information can be viewed simultaneously on multiple devices.

[0046] According to embodiments of the present disclosure, synchronized viewing and operation of multiple devices, such as a projection terminal, a main display terminal, and other terminals, can be achieved based on technologies such as p2p (point-to-point). Any of the projection terminal, main display terminal, and other terminals can be in the form of, but are not limited to, a computer, a mobile phone, or a projector.

[0047] Through the above-mentioned embodiments of the present disclosure, since the projection information of the main display end can be displayed based on other terminals, people in various places who need to participate in watching the projection information can watch the projection information synchronously through the terminal device, which at least partially overcomes the technical problem that some participants cannot see or cannot see the projection information clearly, realizes more efficient and effective implementation of information sharing, and improves the user experience in receiving information.

[0048] In conjunction with specific embodiments, Figure 2 The method shown is further explained.

[0049] According to the embodiments of the present disclosure, due to screen resolution, DPI, and other factors, it is necessary to perform effective calculation and conversion of the DPI, resolution, and other aspects of various devices so that the projection end, the main display end, and other terminals can synchronously display consistent projection information. This is mainly reflected in the conversion of DPI (dots per inch, i.e., print resolution). DPI can represent the number of dots that can be printed per inch. Different display devices may have different resolutions, DPI, and other aspects.

[0050] According to an embodiment of the present disclosure, operation S202 may include: in response to a screen projection request, obtaining a first print resolution of the projection terminal and a second print resolution of the main display terminal; determining a first conversion coefficient based on the first print resolution and the second print resolution, the first conversion coefficient being used to convert the second print resolution to the first print resolution; and displaying the projection information on the main display terminal at the first print resolution based on the first conversion coefficient.

[0051] For example, the first conversion coefficient may be equal to the ratio of the first print resolution to the second print resolution. In this case, when the main display terminal receives projection information that needs to be displayed at the second print resolution, the projection information that needs to be displayed at the second print resolution may be converted to projection information at the first print resolution based on the first conversion coefficient and displayed on the main display terminal.

[0052] For example, the first conversion coefficient may be equal to the first printing resolution. In this case, the second printing resolution can be directly modified to the value represented by the first conversion coefficient, so that the main display terminal can display the projection information at the first printing resolution.

[0053] According to an embodiment of the present disclosure, operation S203 may include: in response to the synchronous display request, obtaining a sum of the second print resolution of the primary display terminal and the third print resolution of the other terminal; determining a second conversion coefficient based on the second print resolution and the third print resolution, the second conversion coefficient being used to convert the second print resolution to the third print resolution; and transmitting the projection information to the other terminal at the third print resolution based on the second conversion coefficient.

[0054] For example, the second conversion coefficient may be equal to the ratio of the third print resolution to the second print resolution. In this case, when the master display terminal receives a synchronous display request, the projection information displayed on the master display terminal at the second print resolution may be converted to projection information that needs to be displayed at the third print resolution based on the second conversion coefficient, and then sent to other terminals for display.

[0055] For example, the second conversion coefficient may be equal to the third print resolution. In this case, the second print resolution can be directly modified to the value represented by the second conversion coefficient, so that the projection information that needs to be displayed at the third print resolution can be sent to other terminals for display.

[0056] It should be noted that the first conversion coefficient may also be equal to the ratio of the second printing resolution to the first printing resolution, or equal to the second printing resolution. The second conversion coefficient may also be equal to the ratio of the second printing resolution to the third printing resolution, or equal to the second printing resolution. However, in this case, the main display end needs to send a print resolution conversion request to the projection end or other terminal to request the projection end to convert its own first printing resolution to the second printing resolution, or to request the other terminal to convert its own third printing resolution to the second printing resolution, and normal projection at the corresponding terminal can only be achieved if the projection end or other terminal accepts the request.

[0057] Through the above-mentioned embodiments of the present disclosure, the consistency of the projection information displayed by the projection terminal, the main display terminal, and other terminals can be effectively improved. In addition, the conversion of the print resolution by the main display terminal can reduce the complicated operations on the projection terminal and other terminals, and improve the accuracy and completeness of the display of the projection information.

[0058] According to an embodiment of the present disclosure, the projection terminal can be defaulted to the master terminal, which is used to control the projection content and operation data and other information. The operation data can represent data generated in response to an operation instruction acting on the projection content. The operation instruction can include at least one of the following: scrolling instruction, annotation instruction, comment instruction, etc., but is not limited to these. For example, it can also include mouse movement, click instruction, etc.

[0059] According to the embodiments of the present disclosure, each terminal or device such as the projection terminal, the main display terminal, and other terminals can be connected through a network. All operating data and projection content can be effectively transmitted through the network.

[0060] During the process of implementing the concept of the present disclosure, the inventors discovered that conventional screen sharing methods can only synchronize the viewing of multiple users, but cannot set a master terminal. In other words, only the screen projection terminal can operate operations such as scrolling the screen.

[0061] According to the embodiments of the present disclosure, the master terminal can be set up and transferred in the same state. For example, when the master terminal needs to be switched, the current master terminal can view all devices connected to the current projection network and can select the corresponding device to transfer the master terminal authority. Any device that has been connected to the current projection network can also send a master terminal authority transfer request to the current master terminal, and if the current master terminal accepts the master terminal authority transfer request, the master terminal authority can be granted to the device that issued the request. The overall process is convenient and fast.

[0062] According to an embodiment of the present disclosure, the master terminal authority may include at least one of the following: the authority to control the display of the projection content to be projected, the authority to operate on the projection content, etc., and may not be limited thereto.

[0063] Figure 3 The schematic diagram shows the overall flow chart of screen projection, synchronous display and collaboration among multiple devices such as the projection terminal, the main display terminal, and other terminals according to an embodiment of the present disclosure.

[0064] like Figure 3 As shown, the user can perform screen projection operations through the projection terminal 310. The projection terminal 310 can be defaulted to the initial master terminal with display authority and operation authority, and can display the projection content and operation data on the large-screen terminal 320. At this time, other devices 330 (for example, can include multiple receiving terminals such as receiving terminal A 331, receiving terminal N 332, and is not limited to this) can obtain the projection content and operation data from the projection terminal 310 and displayed on the large-screen terminal 320 by connecting to the large-screen terminal 320, so as to achieve the effect of synchronous display of multiple devices such as receiving terminal A 331 and receiving terminal N 332, solve the problem of unclear vision caused by small screen or small text in the meeting room, and solve the problem of participation needs of some people who cannot attend the meeting.

[0065] According to the embodiments of the present disclosure, in actual applications, in addition to setting the projection terminal 310 as the main control terminal, other receiving terminals A 331 or N 332 or large-screen terminals 320 simultaneously connected to the system can also be set as the main control terminals to meet various scenario requirements.

[0066] For example, combined with Figure 3As shown, when the receiving terminal A 331 or the receiving terminal N 332 is set as the master terminal with display permission and operation permission, the receiving terminal A 331 or the receiving terminal N 332 can send the screen content and operation data that need to be projected to the large screen terminal 320 for display, and forward it to the receiving terminal N 332 or the receiving terminal A 331 via the large screen terminal 320, and the projection terminal 310 for synchronous display.

[0067] For example, combined with Figure 3 As shown, when the large-screen terminal 320 is set as the main control terminal with display authority and operation authority, the large-screen terminal 320 can directly display the projection content and operation data that need to be projected, and can send the projection content and operation data to the receiving terminal A 331, the receiving terminal N 332, and the projection terminal 310 for synchronous display.

[0068] According to an embodiment of the present disclosure, when other terminals only obtain operation permissions for operating the projected content, operation instructions for operating the projected content are obtained from other terminals. The operation instructions are sent to the projecting terminal, so that the projecting terminal responds to the operation instructions, operates on the projected content, generates operation data, and sends the operation data to the main display terminal. The projected content and operation data are displayed based on the main display terminal.

[0069] For example, combined with Figure 3 As shown, when receiving terminal A 331 or receiving terminal N 332 is set to have only operation authority and display authority belongs to the projection terminal 310, receiving terminal A 331 or receiving terminal N 332 can generate an operation instruction and send the operation instruction to the large screen terminal 320, which is then forwarded to the projection terminal 310 via the large screen terminal 320 for response and generation of operation data. At this time, the projection terminal 310 can send the projection content and the operation data generated in response to the operation instruction from receiving terminal A 331 or receiving terminal N 332 to the large screen terminal 320 for display, and forward it to receiving terminal N 332 or receiving terminal A 331 via the large screen terminal 320 for synchronous display.

[0070] For example, combined with Figure 3 As shown, when the large-screen terminal 320 is set to have only operation authority and the display authority belongs to the projection terminal 310, the large-screen terminal 320 can generate an operation instruction and directly send the operation instruction to the projection terminal 310 for response, thereby generating operation data. At this time, the projection terminal 310 can send the projection content and the operation data generated in response to the operation instruction from the large-screen terminal 320 to the large-screen terminal 320 for display, and forward it to the receiving terminal N332 or the receiving terminal A331 via the large-screen terminal 320 for synchronous display.

[0071] In any embodiment, the end with display authority can serve as the master end, which can be responsible for receiving operation instructions from itself or from other ends, such as scrolling data up or scrolling data down, etc., and is responsible for synchronously transmitting the projected content and the operation data generated in response to the operation instructions to each end for display.

[0072] According to the embodiments of the present disclosure, the process of projecting operational data can be characterized as follows: when the main control terminal performs an operation on the screen, such as scrolling, the screens of all other terminals will also scroll accordingly. Combined with the aforementioned effective calculation conversion of DPI, resolution, etc., it is possible to accurately calculate the synchronous and accurate scrolling of each different device when operating on the main control terminal.

[0073] It should be noted that in actual applications, any one of the projection end 310, the large screen end 320, and the other devices 330 can be used as the main control end, and can obtain only at least one of the display permission and the operation permission. The relevant implementation method is similar to the above embodiment and will not be repeated here.

[0074] Through the above-mentioned embodiments of the present disclosure, operation instructions can be effectively combined so that users on multiple terminals can operate the screens of other users, realize multi-device collaboration, and help improve the flexible expansion capabilities of screen sharing scenarios.

[0075] Figure 4 A flowchart of a method for synchronizing screen projection information based on other terminals according to an embodiment of the present disclosure is schematically shown.

[0076] like Figure 4 As shown, the method includes operations S401 to S402.

[0077] In operation S401, a synchronous display request for synchronously displaying the projection information from the main display end is sent to the main display end, so that the main display end responds to the synchronous display request and sends the projection information displayed by the main display end to other terminals, wherein the projection information is the projection information from the projection end displayed by the main display end in response to the projection request from the projection end.

[0078] In operation S402, screen projection information is read and displayed based on other terminals.

[0079] According to the embodiments of the present disclosure, a screen projection application can be developed, which works on the screen projection end and other terminals. When the screen projection end is projecting, it is responsible for collecting projection information and uploading it to the large screen. When other terminals are used to receive projection information, they are responsible for receiving data from the large screen end and performing local rendering and display.

[0080] According to the embodiments of the present disclosure, regarding the implementation of the method for synchronizing screen projection information based on other terminals, please refer to the aforementioned implementation of the method for synchronizing screen projection information based on the main display terminal, which will not be repeated here.

[0081] Through the above-mentioned embodiments of the present disclosure, a method for synchronous operation of multiple devices based on screen projection is realized, including a same-screen viewing function, which allows multiple devices to simultaneously view the projected content without the need for screen sharing in video conferencing, which is convenient and fast, saving conference resource expenses. Furthermore, a same-screen operation function is realized, which allows multiple devices to operate other devices through the master terminal, which is flexible and scalable.
