Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. Embodiments of the application and features of the embodiments may be combined with one another arbitrarily without conflict. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.

In order to facilitate understanding of the technical solution provided by the embodiments of the present application, some key terms used in the embodiments of the present application are explained here:

Conference: the conference in the embodiment of the application refers to a scene in which a plurality of objects can participate in screen sharing, and the scene includes, but is not limited to, online conference, online classroom, multi-person screen sharing and the like.

And (3) a main control object: the present invention relates to a participant that plays a main control and guiding role in a conference, and for example, for an online conference, the participant may be a host or a presenter, or for an online classroom, the participant may be a teacher or a classmate designated by the teacher, or the like.

Sharing a screen: in a conference, the content displayed on the screen of the presenter can be shared to other participant objects for viewing through the initiation of screen sharing, and after the initiation of screen sharing, the operation performed on the screen can also be seen by other participant objects, such as opening a file, or switching pages of the file, etc., so that the presenter can synchronize the content required to be presented to the presenter to other participant objects for viewing in real time. The content in the shared screen may be the whole screen of the sharer, or may be a selected area, for example, a window corresponding to a certain application software, or a window where a certain file is located.

Split screen display: the method refers to split-screen display in the same display screen, namely, a display screen is divided into a plurality of sub-areas, each content to be displayed occupies a sub-area, and in the embodiment of the application, the shared screen display area of the conference interface is specifically divided into a plurality of sub-areas, and each sub-area is used for displaying a shared screen.

The following briefly describes the design concept of the embodiment of the present application.

Online conferences are becoming increasingly widely used due to their convenient nature. The screen sharing function provided in the online conference further improves the convenience of the online conference, in the related technology, the online conference can only share the screen by one object, if other objects also need to share the screen, the object needing to share the screen at present exits from sharing first, then the screen is shared by other objects, if a plurality of or multiple times of participation in the discussion of the object sharing screen exists, the sharing screen needs to be switched back and forth for multiple times, the operation is complicated, and the conference efficiency is low. And can't realize the contrast of the same screen, when needing the interactive contrast between a plurality of shared screens, the scheme of single shared screen obviously can't realize.

Based on this, the embodiment of the application provides a multi-screen sharing method, in which, when at least one participant exists in a conference interface to perform screen sharing, other participants still can initiate screen sharing operation, at this time, at least one participant and a newly added shared screen can be displayed in a split screen manner according to a preset display mode corresponding to the total number of shared screens to be displayed in the conference interface, that is, multiple shared screens can be displayed simultaneously, and also can facilitate interactive comparison of multiple screens simultaneously, meanwhile, the participant that has initiated the shared screen does not need to withdraw from sharing first, then share the screen by other participants, that is, multiple times of back and forth switching of the shared screen is not needed, thereby reducing the complexity of operation and improving conference efficiency.

In addition, when multiple persons share the screen, the embodiment of the application also provides authentication logic for different participant objects, so that the participant objects can control the shared screens in a dividing and limiting level, and also provides control logic when the shared screens are increased or decreased, so that the display of the shared screens in various numbers can be adapted.

The following description is made for some simple descriptions of application scenarios applicable to the technical solution of the embodiment of the present application, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present application, but not limiting. In the specific implementation process, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

The scheme provided by the embodiment of the application can be suitable for most conference scenes, such as on-line conferences, on-line classes and the like. As shown in fig. 1, a schematic view of an application scenario provided in an embodiment of the present application may include a terminal device 101 and a server 102.

The terminal device 101 may be any device with a conference function, such as a mobile phone, a tablet computer (PAD), a notebook computer, a desktop computer, a smart television, an intelligent vehicle-mounted device, and an intelligent wearable device. The terminal device 101 may be provided with a conference Application (APP), which may be a software client, or may be a client such as a web page or an applet, and the server 102 is a server corresponding to the software or the web page or the applet, which is not limited to the specific type of the client in the embodiment of the present application. The server 102 may be, for example, a stand-alone physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, i.e., a content delivery network (Content Delivery Network, CDN), and basic cloud computing services such as big data and an artificial intelligence platform, but is not limited thereto.

It should be noted that, the method of multi-screen sharing in the embodiment of the present application may be executed by the terminal device 101 alone, or may be executed by the server 102 and the terminal device 101 together. For example, a conference interface corresponding to a first participant object participating in the target conference is presented by the terminal device 101; the conference interface displays a shared screen of at least one participant object participating in the target conference; in response to the screen sharing operation triggered during the target conference, in the conference interface, according to the preset display mode corresponding to the total number of shared screens to be displayed, at least one participant and the newly added shared screen are displayed in a split screen manner, that is, the whole process is performed in the terminal device 101. After the terminal device 101 presents the conference interface corresponding to the target conference, when the screen sharing operation is triggered, the server 102 responds, and sends the content of the shared screen to be displayed to the terminal device 101 of each participant object, and then the terminal device 101 displays the shared screen. The present application is not particularly limited herein, and the following is mainly exemplified by the example in which the server 102 and the terminal device 101 are commonly executed.

For example, where server 102 and terminal device 101 are implemented together, both server 102 and terminal device 101 may include one or more processors, memory, and interface with interactive I/O, etc. The server 102 and the terminal device 101 establish a connection through an interactive I/O interface, and respective memories may store program instructions that are required to be executed by each of the multi-screen sharing methods provided in the embodiments of the present application, where the program instructions when executed by the processor may be used to implement the multi-screen sharing processes provided in the embodiments of the present application, for example, program instructions that display a conference interface and related processes of operation processing at the conference interface may be stored in the terminal device 101 to be executed by the processor of the terminal device 101 to implement the processes, and program instructions that implement synchronization of display contents on each of the terminal devices 101 in response to the operation processing may be stored in the server 102 to be executed by the processor of the server 102 to implement the processes.

In a possible implementation manner, the method of the embodiment of the present application may be applied to an online conference scenario, after a first participant enters a target conference, a conference interface of the target conference may be presented on a terminal device of the first participant, where the conference interface may display a shared screen of at least one participant participating in the target conference in the conference interface, and in the case where a shared screen already exists, screen sharing may still be initiated, so when a second participant initiates a screen sharing operation, the shared screen of the second participant is also displayed in the conference interface, and split-screen display is performed according to a preset display mode corresponding to the total number of displayed shared screens. Specifically, when the second participant initiates the screen sharing operation, the server 102 receives the screen sharing data stream of the second participant, where the screen sharing data stream carries the current screen content of the second participant, and sends the screen sharing data stream to each participant, so as to present a conference interface containing the current screen content of the second participant on the terminal device 101 of each participant. It should be noted that, in the actual application scenario, the first participant object and the second participant object may be the same or different, that is, in a conference, one participant object may be a viewer sharing a screen at the same time or may share an initiator of the screen.

In the embodiment of the present application, each terminal device 101 and the server 102 may be directly or indirectly connected through one or more networks 103. The network 103 may be a wired network, or may be a Wireless network, for example, a mobile cellular network, or may be a Wireless-Fidelity (WIFI) network, or may be other possible networks, which are not limited in this embodiment of the present application.

It should be noted that, the number of terminal devices and servers shown in fig. 1 is merely illustrative, and the number of terminal devices and servers is not limited in practice, and is not particularly limited in the embodiment of the present application.

The technical scheme of the embodiment of the application can be realized based on Cloud technology (Cloud technology), wherein the Cloud technology is a hosting technology for integrating hardware, software, network and other series resources in a wide area network or a local area network to realize calculation, storage, processing and sharing of data.

Cloud technology (Cloud technology) is based on the general terms of network technology, information technology, integration technology, management platform technology, application technology and the like applied by Cloud computing business models, and can form a resource pool, so that the Cloud computing business model is flexible and convenient as required. Cloud computing technology will become an important support. Background services of technical networking systems require a large amount of computing, storage resources, such as video websites, picture-like websites, and more portals. Along with the high development and application of the internet industry, each article possibly has an own identification mark in the future, the identification mark needs to be transmitted to a background system for logic processing, data with different levels can be processed separately, and various industry data needs strong system rear shield support and can be realized only through cloud computing.

The cloud conference is one of cloud technologies, and the conference pointed by the embodiment of the application can comprise the cloud conference, and the cloud conference is an efficient, convenient and low-cost conference form based on the cloud computing technology. The user can rapidly and efficiently share voice, data files and videos with all groups and clients in the world synchronously by simply and easily operating through an internet interface, and the user is helped by a cloud conference service provider to operate through complex technologies such as data transmission, processing and the like in the conference.

Currently, a cloud conference mainly focuses on service contents mainly in a Software as a service (SaaS) mode, including service forms such as telephone, network, video and the like, and a video conference based on cloud computing is called a cloud conference.

In the cloud conference era, the transmission, processing and storage of data are all processed by the computer resources of video conference factories, and users can carry out efficient remote conferences without purchasing expensive hardware and installing complicated software.

The cloud conference system supports the dynamic cluster deployment of multiple servers, provides multiple high-performance servers, and greatly improves conference stability, safety and usability. In recent years, video conferences are popular for a plurality of users because of greatly improving communication efficiency, continuously reducing communication cost and bringing about upgrade of internal management level, and have been widely used in various fields of transportation, finance, operators, education, enterprises and the like. Undoubtedly, the video conference has stronger attraction in convenience, rapidness and usability after the cloud computing is applied, and the video conference application is required to be stimulated.

The method of multi-screen sharing provided by the exemplary embodiments of the present application will be described below with reference to the accompanying drawings in conjunction with the application scenarios described above, and it should be noted that the application scenarios described above are only shown for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in any way in this respect.

Referring to fig. 2, a flow chart of a method for multi-screen sharing according to an embodiment of the present application is shown, and a specific implementation flow of the method is as follows:

Step 201: presenting a conference interface corresponding to a first participant in the target conference; the conference interface displays a shared screen of at least one participant object participating in the target conference.

In the embodiment of the application, the conference APP can be installed on the first terminal equipment, so that the first participant can enter the target conference through the conference APP, and then a conference interface corresponding to the target conference is presented on the first terminal equipment, and the situation that at least one participant has been subjected to screen sharing is assumed, so that a shared screen of at least one participant is displayed on the conference interface.

Referring to fig. 3a, a schematic diagram of a conference interface of a participant initiating screen sharing according to an embodiment of the present application is shown. In particular, in fig. 3a, screen sharing is taken as an example when 1 participant currently exists, and the conference interface in fig. 3a displays the shared screen a of the first participant, and when the first participant is not a participant initiating screen sharing, the content displayed in the conference interface may be different, for example, the operation controls are different, which is not limited in the embodiment of the present application.

In practical application, after the screen sharing is initiated, the first participant can select to share part or all of the content displayed on the screen on the first terminal device to other participant, so that the content shared by the first participant can be displayed in the conference interface of the other participant. For example, the first participant may choose to share the entire screen of the first terminal device with other participants, so that in the conference interface of other participants, the entire screen of the first terminal device may be displayed, and the operations performed by the first participant on the first terminal device may be synchronized with other participants; or the first participant can also select to share part of the screen content displayed in the first terminal device to other participant objects, for example, the interface of the document APP can be shared to other participant objects, so that in the conference interface of the other participant objects, the document content opened by the first participant object can also be displayed.

Step 202: and responding to the screen sharing operation triggered by the target conference, and in the conference interface, carrying out screen division display on the at least one participant object and the newly added shared screen according to a preset display mode corresponding to the total number of the shared screens to be displayed.

In the embodiment of the application, in order to improve the conference efficiency, a multi-screen sharing function is provided, namely, the screen sharing operation can still be continuously initiated under the condition that the shared screen exists, and a plurality of shared screens can be simultaneously displayed in a conference interface.

Referring to fig. 3b, a schematic diagram of a conference interface of a participant that does not initiate screen sharing is provided in an embodiment of the present application. Here, assuming that the second participant object is a participant object that does not initiate screen sharing, as shown in fig. 3b, in addition to displaying the shared screen a of the first participant object on the conference interface corresponding to the second participant object, an operation control for triggering screen sharing may be displayed, and if the "initiate sharing" operation button shown in fig. 3b is displayed, the second participant object may operate the same to trigger screen sharing. Of course, the screen sharing operation may be triggered in other manners, such as a shortcut or other possible manners, which the embodiments of the present application do not limit.

In practical application, the conference interface of each participant needs a server to provide background services. That is, after the second participant initiates the screen sharing, the second terminal device corresponding to the second participant initiates a screen sharing request to the server, and if the server determines that the target conference is to allow multi-screen sharing, a transmission connection of video data is established between the second terminal device of the second participant and the screen sharing request of the second participant, so that the server can obtain the shared screen data of the second participant from the second terminal device, and based on the screen data, the server also sends new shared screens to all the participants of the target conference, that is, the screen data of the shared screen of the second participant, so that the shared screen of the second participant can be displayed on the conference interface of each participant. It should be noted that, the second participant object that does not initiate the shared screen is described here as an example, but is not limited to initiating participant objects that can only not initiate the shared screen, and in practical application, the new screen sharing may be initiated by participant objects that have initiated the shared screen.

Referring to fig. 3c, a schematic diagram of a conference interface with multi-screen sharing according to an embodiment of the present application is shown, where after a second participant initiates screen sharing, a shared screen of the second participant may be displayed in the conference interface, as shown in fig. 3c, in addition to the existing shared screen a, a shared screen B of the second participant may be further displayed, so that multiple shared screens may be simultaneously displayed in a split screen in the conference interface.

In one possible implementation, to facilitate the presentation effect of the presenter during the target conference, the shared screen displayed in the conference interface corresponding to each participant may be the same during the entire conference, e.g., before the second participant initiates sharing, the conference interfaces of the second participant and the first participant each display only the shared screen a, and after the second participant initiates sharing, the conference interfaces of the second participant and the first participant may both display the shared screens a and B simultaneously.

In one possible implementation, in order to facilitate personalized display of different meeting objects during the meeting, each meeting object may also select a shared screen to be displayed in a manner that is preferred by itself, for example, after the second meeting object initiates sharing, the shared screen a or B may be selected to be displayed on the meeting interface.

In the embodiment of the application, when the conference interface is displayed, the preset display modes of the shared screens can be determined according to the total number of the shared screens required to be displayed in the conference interface, and then the shared screens can be displayed according to the preset display modes. The preset display modes can be configured under a specific number, can be configured by default of the conference APP, and can be configured according to preference of a participant.

Referring to fig. 4, a schematic diagram of configuring a preset display mode is shown. The configuration of the preset display mode can be configured by a main control object of the target conference, or the preset display mode of the history configuration of the main control object is automatically used, and, of course, each participant object can also select the configuration of the preset display mode by itself in order to facilitate the personalized display of different participant objects in the conference process.

As shown in fig. 4, in the configuration interface, a preset display mode employed when different numbers of shared screens are used may be configured. If two shared screens exist, display modes such as a left screen and a right screen, an upper screen and a lower screen or a stacked screen can be selected, and the preset display mode is set as the left screen and the right screen; when three shared screens exist, a display mode such as a ' delta ' mode, an inverted delta ' mode or an ' L ' mode can be selected, and the preset display mode is set to be a ' delta ' mode; when there are four shared screens, a display mode such as "field-shape" or "L-shape" may be selected, and the preset display mode set here is "field-shape". Of course, the display modes described above are merely examples, and other possible display modes may be adopted in actual use, and further shared screens may exist, which is not limited in the embodiment of the present application.

Along the above example, when the second participant starts the screen sharing, there are two shared screens, i.e. shared screens a and B, and then the shared screens a and B may be displayed in a preset display mode, i.e. in a left-right split manner, as shown in fig. 3 c.

In the embodiment of the application, in order to facilitate the control of the displayed shared screens, screen operation controls for the shared screens can be displayed in the conference interface, and the shared screens can be rapidly controlled through the screen operation controls.

In one possible implementation, considering that the random control of the participant object may make the conference process not smooth, for example, in the process of speaking, a participant object may shut down the shared screen of other people by mistake, which is unfavorable for the progress of the conference process, different participant objects may be given different levels of authority, and different levels of authority have different operation authorities, so as to avoid these situations.

Embodiments of the present application may include, but are not limited to, the following levels of rights:

(1) And the first-level authority has the operation authority for all shared screens in the target conference. Generally, the first level authority is to perform overall control on the whole process of the target conference, so that the participant object given the first level authority should be an overall controller in the target conference, such as a host or a presenter, and the like.

(2) And the second level of rights only has the operation rights of the shared screen of the second level of rights. The second level permission is convenient for the participant object initiating the shared screen to quickly control the shared screen of the participant object, and the participant object with the second level permission can control the shared screen of the participant object and cannot operate the shared screens of other participant objects.

(3) The third level authority does not have any operation authority of the shared screen, namely, the third level authority can only be displayed on the conference interface, but cannot operate any shared screen.

In the embodiment of the application, when the conference interface is displayed, corresponding display is needed according to the authority level of the current participant, and based on the corresponding display, the embodiment of the application adds the authentication module which is used for realizing the authentication logic of different participant objects for operating different shared screens. The authentication module can be deployed in the client or in the server.

Referring to fig. 5, a schematic flow chart of the authentication logic implemented by the authentication module is shown. Here, the first reference object is described as an example because the authentication logic for any reference object is similar.

Step S1: it is determined whether the first participant object is the master object of the target conference.

Step S2: if the result of step S1 is yes, that is, the first reference object is the master control object, it is determined that the first reference object has the first level authority.

In the scene of multi-screen sharing, the participant objects are mainly classified into three types, i.e., a conference host, a participant with a shared screen, and a participant without a shared screen, and the shared screen of the conference interface may be classified into two types, i.e., a shared screen of own and a shared screen of other than own. The main control object has the highest authority of the target conference, namely the first level authority, and can operate all shared screens, including own shared screens and shared screens which are not own, so that when the first reference object is determined to be the main control object, the first reference object can be determined to have the first level authority, and in the subsequent operation process, the operation authority of the first reference object can be controlled according to the first level authority.

Step S3: if the result of step S1 is no, that is, the first reference object is not the master control object, it is determined whether a shared screen exists currently.

Step S4: if yes in step S3, it is determined whether at least one reference object of the current shared screen includes the first reference object.

Step S5: if the result of step S4 is yes, i.e. at least one of the participant objects comprises a first participant object, it is determined that the first participant object has a second level of rights.

Step S6: if the result of step S3 or step S4 is no, it is determined that the first reference object has the third level authority.

Specifically, when the first reference object is not the master control object, it is required to determine the authority of the first reference object according to whether the first reference object has a shared screen, that is, if there is no shared screen currently, the first reference object must not have screen sharing, then the first reference object is third-level authority, and if there is a shared screen, it is required to further determine whether the first reference object has its own shared screen, that is, whether at least one reference object that initiates sharing currently includes the first reference object, if so, the first reference object is second-level authority, and if not, the first reference object does not have screen sharing, that is, third-level authority.

In the embodiment of the application, the content displayed on the conference interface can be different corresponding to different levels of authorities.

When the first participant has the first level of authority in the target conference, as shown in fig. 3c, in the conference interface of the first participant, screen operation controls of all the shared screens may be displayed, and then the first participant may perform screen management for any shared screen.

In one possible implementation, as can be seen in fig. 3c, each shared screen may correspond to a corresponding screen operation control, and the different shared screens are controlled independently.

In practical application, the screen operation control of each shared screen can be displayed at the corresponding position of the shared screen, for example, the screen operation control can be displayed at the upper left corner position of the shared screen as shown in fig. 3c, and of course, the screen operation control can also be displayed at other possible positions. Or the position of the screen operation control of each shared screen may be adjustable, for example, after the screen operation control is selected, it may be dragged to any position.

In one possible implementation, considering that there is a correspondence between the screen operation control and the shared screen, in order to avoid a situation that it is impossible to determine which shared screen the screen operation control corresponds to, a dragging range of the screen operation control may be limited, for example, dragging may be performed only in a shared screen area, as in fig. 3c, for the screen operation control of the shared screen a, dragging may be performed only in the shared screen a range.

In one possible implementation, to avoid the situation that it is impossible to determine which shared screen the screen operation control corresponds to, a corresponding shared screen identifier may also be added to each screen operation control. Referring to fig. 6a, an identifier of the shared screen a may be added to a screen operation control of the shared screen a, and an identifier of the shared screen B may be added to a screen operation control of the shared screen B, where the screen operation control may be dragged at any position in the conference interface in a floating window manner.

In the embodiment of the present application, if the first participant has the second level permission of the target conference, then in the conference interface, a screen operation control corresponding to the shared screen of the first participant is displayed, as shown in fig. 6B, in the conference interface of the first participant, the shared screen B is the shared screen of the second participant, the shared screen a is the shared screen of the first participant, then only the screen operation control of the shared screen a may be displayed, and then the first participant may only perform screen management for the shared screen a shared by itself.

It should be noted that, the display in the embodiment of the present application may be interpreted as follows:

In the first case, when the first participant object is the second level of rights, only the screen operation control of the shared screen a of the first participant object is displayed, and the screen operation control of the other shared screens is not displayed, i.e. as shown in fig. 6 b.

In the second case, when the first reference object is the second level of rights, all screen operation controls of the shared screen are displayed, but the states of the screen operation controls are different, see the case shown in fig. 6 c. For example, the screen operation control of the non-first participant is in an inoperable state, or the screen operation control of the non-first participant is in an unresponsive state, i.e., operable but not responsive to a corresponding action.

In the embodiment of the present application, operations on a shared screen may be classified into two types:

(1) The shared screen, i.e., an operation performed for a specific shared screen, is controlled, such as turning on the shared screen, turning off the shared screen, maximizing the shared screen, minimizing the shared screen, screen position dragging, and the like.

(2) The display mode of the shared screen is switched, for example, the split screen type is switched, for example, the left and right split screens are switched to the upper and lower split screens, or the shared screen is zoomed, etc.

In the following, the description will be made separately for different operations.

In the embodiment of the present application, the screen operation controls include first-type screen closing controls, where each first-type screen closing control corresponds to a shared screen, see the screen closing control shown in fig. 6 a.

Then, the participant object may operate for a first type of screen closing control of the shared screen in the current conference interface, further, close the shared screen corresponding to the first type of screen closing control in response to the operation for the first type of screen closing control, and, because one of the shared screens is closed, the number of the shared screens is changed, and then the remaining shared screens need to be displayed in a preset display mode corresponding to the number of the remaining shared screens.

For example, when the current conference interface displays 4 shared screens and when one shared screen is closed by the participant, 3 shared screens remain, the conference interface needs to be displayed according to the display mode of the 3 shared screens, for example, according to the default delta shape in fig. 4; if one of the shared screens is continuously closed, 2 shared screens remain, and the conference interface needs to be displayed according to the display mode of the 2 shared screens, for example, according to the default left-right split screen mode in fig. 4; if one of the shared screens is continuously closed, 1 shared screen remains, and the conference interface needs to perform full-screen display according to the display mode of 1 shared screen, for example, after the first type screen closing control of the shared screen B in fig. 3c is operated, the conference interface as shown in fig. 3a or fig. 3B may be presented, but it should be noted that full-screen display refers to full-screen display in the conference interface, that is, the conference interface may include an area for displaying the shared screen, and when only 1 shared screen remains, the shared screen exclusively displays the two full-screen display areas.

In addition, it should be noted that, in an actual scenario, a host or a host, etc. master objects may close the shared screen opened by all the participant objects, while other participant objects may close only the shared screen opened by themselves.

Further, in order to avoid the error closing of the shared screen, after the reference object triggers the operation of closing the shared screen, the operation may be authenticated, that is, it is determined whether the reference object has the right to close the shared screen, that is, when the reference object is the master control object, it has the right to close the shared screen opened by all the reference objects, then the triggered operation of closing the shared screen may be responded, and when the reference object is another reference object, it is necessary to further determine whether the shared screen closed by the reference object is the shared screen of the reference object itself, if yes, the triggered operation of closing the shared screen may be responded, and if not, the operation of closing the shared screen triggered by the reference object is refused.

In practical application, taking the second participant object to close the shared screen B as an example, after the second participant object initiates the shared screen closing operation for the shared screen B, the second terminal device corresponding to the second participant object initiates a screen closing request to the server, and when the server determines that the second participant object has the right to close the shared screen B, the server can respond to the screen closing request of the second participant object, thereby closing the transmission connection of the video data established between the second terminal devices, and the server also indicates that all the participant object shared screens B have been closed, so that the shared screen B can be closed on the conference interface of each participant object.

In the embodiment of the present application, the screen operation controls include a second type of screen closing control, where the second type of screen closing control is used to close all other shared screens except for a specific shared screen, as shown in fig. 7, and includes operation buttons such as "only allow lecturer to share screen" option and "empty all shared screens", and then the second type of screen closing control may be used to close multiple shared screens.

When an operation is performed on the second type screen closing control displayed in the conference interface, all other shared screens except the specific shared screen are closed in response to the operation, and the specific shared screen is displayed in full screen in the conference interface.

In the embodiment of the application, the specific shared screen can be the shared screen corresponding to the main control object, or can be selected from all the shared screens. Taking a specific shared screen as an example of a shared screen corresponding to a main control object, in general, the second type screen closing control only has authority to the main control object, that is, the main control object can operate for the second type screen closing control of the shared screen in the current conference interface, further, in response to the operation for the second type screen closing control displayed in the conference interface, the shared screens of all the participant objects except the main control object are closed, and the shared screen of the main control object is displayed in the conference interface in a full screen. The host object may be, for example, a host or a presenter of the current conference, but it should be noted that the host or the presenter has the operation right of the second type screen closing control, but the specific shared screen may be a screen shared by the host or the presenter, or may not be a screen shared by the host or the presenter.

For example, the current conference interface displays 4 shared screens, when the master control object triggers the operation of closing the control on the second type screen, the shared screens of all the participant objects except the master control object are closed, and the shared screens of the master control object are displayed in the conference interface in a full screen.

Similarly, after the second type of screen closing control is triggered by the participant object, the operation can be authenticated, that is, whether the participant object has the right of the second type of screen closing control or not is determined, that is, when the participant object is the main control object, the participant object has the right of closing the shared screen opened by all participant objects, the triggered operation of closing the shared screen can be responded, and when the participant object is other participant objects, the operation of closing the shared screen triggered by the participant object is refused.

When the first participant object is a main control object in actual application, after the first participant object triggers the second type of screen closing control, a screen closing request is initiated to the server by the first terminal device corresponding to the first participant object, when the server determines that the first participant object has the right to close a plurality of shared screens, the screen closing request of the first participant object can be responded, further transmission connection for video data between other terminal devices except the first terminal device is closed, the server also indicates that all other shared screens except the first participant object are closed, so that the other shared screens can be closed on the conference interface of each participant object, and only the shared screen of the first participant object is reserved.

In the embodiment of the application, the screen operation control can further comprise a screen minimizing control, and each screen minimizing control corresponds to one shared screen and is used for realizing the minimizing operation of one shared screen.

Then, the participant object may perform an operation for the target screen minimizing control of the target shared screen in the current conference interface, further perform a screen minimizing operation for the target shared screen corresponding to the target screen minimizing control in response to the operation for the target screen minimizing control, and, since one of the shared screens is minimized, the number of shared screens to be displayed is changed, and then the remaining shared screens need to be displayed in a preset display mode corresponding to the number of remaining shared screens.

Referring to fig. 8a, the current conference interface displays 4 shared screens, when the participant minimizes the shared screen D, and then 3 shared screens remain, and then the conference interface needs to be displayed according to the display mode of the 3 shared screens, that is, referring to fig. 8B, according to the default delta shape, that is, the shared screen a is located in the upper half of the display area, and the shared screens B and C are located in the lower half of the display area; if one of the shared screens is continuously minimized, if the shared screen C is minimized, 2 shared screens remain, and the conference interface needs to be displayed according to the display mode of the 2 shared screens, namely, as shown in fig. 8C, according to a default left-right split screen mode; if one of the shared screens is minimized, for example, after the shared screen B is minimized, 1 shared screen remains, the conference interface performs full-screen display according to the display mode of 1 shared screen, and the shared screen a is displayed full-screen as shown in fig. 8 d.

In the embodiment of the present application, after the target sharing screen performs the screen minimizing operation, the target screen minimizing control corresponding to the target sharing screen is changed to the screen restoring control, as shown in fig. 8b to 8d, the operation button at the original position corresponding to the screen minimizing control is changed to the operation button corresponding to the screen restoring control, in the actual scene, the buttons may be distinguished by changing the icon or changing the display color, which is not shown in fig. 8b to 8 d.

Then, the reference object may also perform an operation on the screen restoration control, and further may perform a screen restoration operation on the target shared screen in response to the operation on the screen restoration control, so that each restored shared screen is displayed in a preset display mode corresponding to the total number of restored shared screens.

For example, referring to fig. 8D, when the screen restore control of the shared screen B is operated, the shared screen B is restored to present the conference interface as shown in fig. 8C, and similarly, when the screen restore control of the shared screen C is continuously operated, the shared screen C is restored to present the conference interface as shown in fig. 8B, and when the screen restore control of the shared screen D is continuously operated, the shared screen D is restored to present the conference interface as shown in fig. 8 a.

Similarly, to avoid mishandling the shared screen, after the participant triggers the operations to minimize or restore the shared screen, the operations may also be authenticated, i.e., to determine whether the participant has the authority to perform the operations, if so, the triggered operations may be responded to, and if not, the operations triggered by the participant are denied.

In practical application, after the participant initiates the shared screen minimizing or restoring operation, the terminal device initiates a corresponding screen operation request to the server, and when the server determines that the participant has the operation right, the server can respond to the screen operation request, and further the server sends an instruction to the terminal devices of all the participant to instruct the terminal devices to present the conference interface after the minimizing or restoring operation.

In the embodiment of the present application, referring to fig. 6a, the screen operation control may further include a display mode switching control, where the display mode refers to an arrangement manner among a plurality of shared screens, and different numbers of shared screens are applicable to different arrangement manners, so that a participant may operate with respect to the display mode switching control in the conference interface, so that the display mode of each shared screen in the conference interface is switched in response to the operation.

In particular, referring to fig. 9a and 9b, after the display mode switching control is operated, a conference interface as shown in fig. 9a or 9b may be presented, wherein at least one display mode option is displayed in the conference interface, and, the display mode indicated by any display mode option displayed is adapted to the number of shared screens to be displayed, as shown in fig. 9a, the number of shared screens presented by the conference interface is 4, and any display mode option displayed is adapted to the 4 shared screens, namely, the display mode option can be in a shape of a Chinese character 'tian' or an L-shape; or as shown in fig. 9b, the number of shared screens presented by the conference interface is 3, and any display mode option displayed is adapted to the 3 shared screens, that is, may be in a delta shape, an inverted delta shape, or an L shape, or the like, and of course, other numbers are also the same, so that a detailed description is omitted. However, when the display mode is switched, the number of the shared screens to be displayed may be determined according to the number of the shared screens to be displayed currently, for example, a total of 4 shared screens are currently displayed, but 2 shared screens are minimized, and only 2 shared screens to be displayed may be displayed as 2 shared screens.

In addition, in the conference interface, the switching of the display modes can be performed for the display mode switching control of any shared screen, namely, the switching of the display modes can be triggered no matter which display mode switching control of the shared screen is operated; or to make the conference interface concise, only one display mode switching control can be displayed.

Specifically, after a selection operation is performed from at least one displayed display mode option, in response to an operation performed on the selected target display mode option, at least one participant and the newly added shared screen are displayed in a split screen mode according to a target display mode corresponding to the target display mode option. For example, as shown in fig. 9a, the 4 currently displayed shared screens are displayed in an L shape, or as shown in fig. 9b, the 4 currently displayed shared screens are displayed in an inverted delta shape.

In order to facilitate the operation of the shared screen during the meeting, for example, when it is necessary to focus on the content of a certain shared screen, it may be necessary to zoom in to view it more clearly, and there is a need to zoom in on the shared screen. Therefore, the embodiment of the application also provides a zoom function for the shared screen.

Specifically, after the scaling operation is performed on the target shared screen displayed in the conference interface, the size of the target shared screen is adjusted in response to the scaling operation performed on the target shared screen displayed in the conference interface, and the sizes of the rest shared screens are adjusted in an adaptive manner according to the size of the target shared screen. Referring to fig. 10a, the zoom operation may be, for example, an operation performed on a zoom control of the target shared screen after the target shared screen is selected, as indicated by a left-right arrow in fig. 10a, to expand and zoom the shared screen C to the right, or as indicated by a 45 ° arrow in fig. 10a, zoom the shared screen C, drag the zoom control to a desired position, and then adaptively zoom the size of other shared screens, as indicated in fig. 10B, and then zoom the sizes of the shared screen a, the shared screen B, and the shared screen D, after the shared screen C is zoomed in.

Therefore, in the actual use process, the shared screen can be freely scaled, the flexibility of screen operation is improved, the content of each shared screen can be flexibly checked, and the conference efficiency is improved.

In addition, the embodiment of the application also provides a function of moving the shared screen, namely, after the target shared screen is selected, the target shared screen is subjected to position adjustment operation, and then the target shared screen is adjusted to the target position designated by the position adjustment operation in response to the position adjustment operation, and as the target position is possibly the position where other shared screens are located, the positions of the other shared screens need to be adjusted in an adaptive manner according to the target position. Referring to fig. 10C, after the sharing screen C is selected, the sharing screen C is dragged to the position of the sharing screen D so that the positions of the sharing screen C and the sharing screen D are exchanged, or 3 sharing screens may be dragged to be in an L-shaped arrangement when 3 sharing screens are in a delta shape. Of course, other movement modes may be used, and embodiments of the present application are not limited in this regard.

In the embodiment of the application, different screen operation controls can be shown in different colors or different patterns, so that a user can quickly find out the corresponding operation controls.

In one possible implementation manner, when a plurality of shared screens are presented, the embodiment of the application can be presented on one display screen; or when a plurality of display screens exist, the display can be performed on the plurality of display screens, and the participant can freely select the shared screen displayed on each display screen.

In one possible implementation manner, the total number of shared screens displayed in the conference interface may be limited due to the consideration of display effects, and when a screen sharing operation initiated by a participant is received, it needs to be determined whether the total number of shared screens displayed in the conference interface is not less than a preset upper limit value, if the total number of shared screens is not less than the preset upper limit value, screen sharing cannot be continued, so that the screen sharing operation triggered by the participant is refused, and a prompt message that the total number of shared screens is not less than the upper limit value is output.

Taking the example of the upper limit value of the number as 4 as shown in fig. 11, when the first participant triggers the screen sharing operation, it needs to be determined whether the total number of the sharing screens displayed in the conference interface is not less than 4, if so, the screen sharing operation can be responded, and if so, the screen sharing operation triggered by the first participant is refused to be responded, and a prompt message of not less than the upper limit value of the number of the sharing screens is output, and if so, 4 sharing screens exist, and if the screen sharing is continuously initiated, a prompt of 'the number of sharing screens exceeds the limit' is output.

Of course, in practical application, the upper limit value of the number of shared screens may be set according to practical situations, for example, the screen of the apparatus used is large enough, and the restriction of the participant objects sharing the screen at the same time may be appropriately released.

In the embodiment of the application, mainly related to the problem of multi-screen sharing, so that the management authority of the multi-screen and the logic of multi-screen display are very important, and for the purpose of system decoupling, an authentication module and a multi-screen display module are established to handle the two problems, wherein the authentication module is introduced above, and the processing logic of the multi-screen display module is introduced below.

Referring to fig. 12, which is a logic diagram of split screen switching when the upper limit value of the number is 4, the following logic exists:

(1) When there is 1 shared screen, the shared screen is displayed full screen in the conference interface.

(2) When there are 2 shared screens, the left and right split screens are displayed by default, and other display modes, such as up and down split screens, can be switched.

(3) When 3 shared screens exist, the display of the character division screen by default can be switched to other display modes, such as inverted character division screen, left-middle-right division screen, upper-middle-lower division screen and the like.

(4) When there are 4 shared screens, the default field character split screen can also be switched to other display modes, such as L-shaped.

(5) When the shared screen is minimized or closed by triggering, the number of the shared screens is reduced by 1, and the display is performed according to the default split screen mode after the reduction of 1.

(6) And when the shared screen is started or restored, adding 1 to the number of the shared screens, and displaying according to a default split screen mode after adding 1.

(7) When a certain shared screen is maximized, the shared screen is displayed full screen.

In the embodiment of the application, the authentication module is not required to be called for authentication when the participant starts the shared screen, but the split-screen display module is required to be called for split-screen display according to the split-screen display logic, and the authentication module is required to be called for authentication when the participant is closed, maximized, minimized and the split-screen mode is adjusted, namely whether the participant has operation authority is confirmed, and the split-screen display module is required to be called for split-screen display according to the split-screen display logic.

In practical application, the authentication module and the split screen display module may be deployed in a server or a client, which is not limited.
