Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments herein may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

Embodiments of the present invention provide a terminal screen content synchronization method.

Referring to FIG. 1, FIG. 1 is a flowchart of a method for synchronizing a content of a terminal screen according to an embodiment of the present invention.

In the embodiment shown in FIG. 1, the terminal screen content synchronization method includes the following steps, that is, steps 110 to 130:

Step 110: Receive a synchronization parameter of a file to be shared sent by the first terminal.

In this embodiment, the remote screen sharing conference scene is taken as an example to explain the terminal screen content synchronization method in the embodiment of the present invention. However, the method in the embodiment of the present invention is not limited to the application scenario in the embodiment, for example, Used for distance learning, remote multi-site video display and other scenes. The first terminal mentioned below is a shared terminal, that is, the originating end of the screen content synchronization, and the second terminal is another terminal that needs to establish a synchronization relationship with the shared terminal, and the number of the terminals may be one or more, during the synchronous conference process. The second terminal and the first terminal are interchangeable.

In the first synchronization meeting, the first terminal or the second terminal first applies to the server to have a certain After the virtual meeting room (that is, the shared group) of the number of seats, the name and password of the virtual meeting room are obtained after the application is completed. After the terminal that needs to participate in the meeting finds the corresponding virtual meeting room, enter the virtual meeting by using the password. Room, establish contact with the server.

After the conference ends, you can keep the virtual conference room. When you synchronize the conference, you do not need to apply for the virtual conference room again. You only need to find the same virtual conference room and enter the virtual conference room directly through the password.

After the first terminal initiates the instruction to start the conference, the server receives the synchronization parameter of the file to be shared sent by the server from the first terminal in real time, and the synchronization parameter may include the number of video frames, the number of pages of the PPT/Word, the pause instruction, or the The page instruction or the like, the first terminal converts the received display instructions to be shared files into synchronization parameters and sends the synchronization parameters to the server, and the server receives the synchronization parameters.

Step 120: When receiving the synchronization parameter, acquire a sharing group to which the first terminal belongs.

Step 130: Send the synchronization parameter to the second terminal in the shared group, so that the second terminal synchronously displays the file to be shared according to the synchronization parameter.

After the files are to be shared and opened, the conference can be started. The file to be shared may be obtained and stored by the second terminal before the conference starts, or before the synchronization parameter is transmitted. Obtained from the first terminal by the server. Since the conference presenter will perform some operations on the shared terminal to explain the content of the conference to the users participating in the conference, during the explanation process, some operations will be performed on the file, such as page turning of the PPT, playing or pause of the video, etc. The first terminal generates the corresponding synchronization parameters by sending the corresponding synchronization parameters to the server, and after receiving the synchronization parameters, the server acquires the shared group (ie, the virtual conference room) to which the first terminal belongs, and sends the synchronization group in real time. Going to the second terminal of the sharing group and converting into a display instruction, and loading the display instructions into the file to be shared displayed on the screen of the second terminal in real time, the screen on the second terminal and the sharing terminal can be realized. The screen displays the files to be shared in real time.

In the method for synchronizing the content of the terminal screen, the server obtains the synchronization parameter of the file to be shared sent by the first terminal, acquires the shared group to which the first terminal belongs, and sends the received synchronization parameter to the shared group. a second terminal, wherein the second terminal synchronously displays the file to be shared according to the synchronization parameter; the foregoing method does not need to transmit the file to be shared during the synchronization process, and only needs to transmit The synchronization parameter can realize the synchronization of the screen content, occupy small memory and fast transmission speed, can realize real-time synchronization, and solve the delay of the terminal screen content in the related art for a long time, and it is difficult to realize the technical problem of real-time synchronization.

On the basis of the flow of the embodiment shown in FIG. 1 , the terminal screen content synchronization method provided in this embodiment may further include the following steps 100 to 103 before the step 110:

Step 100: Receive a file to be shared transmitted by the first terminal, and obtain attribute information of the file to be shared.

Step 101: Determine, according to the obtained attribute information, whether the second terminal stores the file to be shared.

The operation of uploading the file to be shared to the server by the first terminal may be started after the first terminal enters the virtual conference room, and may be before the second terminal enters the virtual conference room, or after the second terminal enters the virtual conference room.

After the first terminal sends the to-be-shared file to the server, the server may obtain the attribute information of the file to be shared, and the server may determine, according to the attribute information of the file to be shared, whether the second terminal stores the file to be shared, for example, Sending an instruction to retrieve the file to be shared to the second terminal, instructing the second terminal to perform the retrieval and transmitting the retrieval result to the server.

Step 102: When it is determined that the second terminal stores the file to be shared, issue an instruction to display the file to be shared to the second terminal that retrieves the file to be shared.

Step 103: When it is determined that the second terminal does not store the file to be shared, send the file to be shared to the second terminal that does not retrieve the file to be shared, for the second The terminal displays the received file to be shared.

When there are multiple second terminals, there may be a second terminal that stores files to be shared, and some second terminals do not store files to be shared. For the second terminal that stores files to be shared, only the files to be shared are issued. The instruction, for the second terminal that does not store the file to be shared, sends the file to be shared to the second terminal.

The terminal screen content synchronization method proposed in this embodiment, the sharing device first transmits the file to be shared Enter the server, so you can reduce many links when synchronizing. If other terminals have files to be shared, you don't need to transfer the files to be shared in the synchronization process. You only need to transfer the synchronization parameters to achieve synchronization. It takes up less memory and has faster transmission speed. Real-time synchronization can be realized; if there are no files to be shared on other terminals, the files to be shared can be obtained from the server in time before the synchronous display, and only the synchronization parameters need to be transmitted in the synchronization process, and the terminal screen content in the related technology is solved. Longer delays make it difficult to achieve real-time synchronization.

Step 105: Send the file to be shared to the second terminal, so that the second terminal displays the file to be shared.

After the first terminal sends the file to be shared to the server, the server receives the file to be shared, and directly sends the file to be shared to all the second terminals, so that all the second terminals display the file to be shared.

In the terminal screen content synchronization method proposed by the embodiment, the sharing device firstly transfers the file to be shared to the server, so that a plurality of links can be reduced when synchronizing, and synchronization can be realized only by transmitting synchronization parameters, occupying small memory and fast transmission speed. Real-time synchronization is possible.

Step 106: After receiving the request instruction for joining the shared group sent by the second terminal, obtain a verification parameter from the request instruction, and determine whether the obtained verification parameter is related to a preset verification parameter. Number matching

Step 107: When the acquired verification parameter matches the preset verification parameter, respond to the request instruction to join the second terminal to the shared group.

When the virtual terminal that is applied to the first terminal or the second terminal is configured with a password, each terminal needs to input the correct password to enter the virtual conference room when logging in to the virtual conference room. When the server receives the terminal request to enter After the instruction of the virtual conference room, the password input by the virtual conference room is obtained, and compared with the preset password. When the preset password is met, the terminal successfully enters the virtual conference room in response to the above instruction.

Optionally, on the basis of the foregoing embodiment shown in FIG. 4, the step 106 may include: after receiving the request for joining the shared group sent by the second terminal, determining, by the group member of the shared group, Whether the number is equal to the preset threshold; when the number of the group members of the shared group is less than the preset threshold, obtaining a verification parameter from the request instruction, determining whether the acquired verification parameter is related to the preset Verify that the parameters match.

When a shared terminal requests a virtual conference room, it will apply according to the number of terminals participating in the conference. The server allocates a certain amount of resources according to the number of terminals, that is, a virtual conference room with a certain number of seats. For example, the virtual conference room allocated by the server has ten seats. When receiving the request to join the shared group, it first determines whether the group member in the shared group has reached the preset threshold. When the group member does not reach the preset threshold, Then judge whether the verification password is correct. When the number of group members has reached the preset threshold, it will receive a notification that the number of seats is full. In other optional embodiments, the password may not be set for the virtual conference room according to the degree of openness of the conference and the user's requirements. When the user finds the corresponding conference room, the user may directly join.
