[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Referring to FIG. 1 , FIG. 1 is a flow chart of a video screen processing method provided by an embodiment of the present invention, the video screen processing method comprising:

[0036] S1. Obtaining a screen editing control mode selected by a master device; wherein the master device is a device of a speaker, and the screen editing control modes include: a speaker control mode and a separate writing control mode;

[0037] S2. In the speaker control mode, the video screens of all participants' devices are controlled to display the main editing area and the written data in the main editing area; wherein the main editing area can be edited by the master device, and the participants include: the speaker and the audience;

[0038] S3. In the separate writing control mode, the video screen of each sub-device is controlled to display the corresponding sub-editing area and the writing data on the corresponding sub-editing area, and the video screen of the main device is controlled to display all the sub-editing areas and the writing data on each sub-editing area; wherein, the sub-device is the device of the listener, and the corresponding sub-editing area can be edited through the sub-device.

[0039] It's understandable that conference participants are divided into speakers and attendees, with each participant's device equipped with an independent editing area. The speaker's device is the master device, with their editing area being the master editing area, while the attendees' devices are sub-devices, with their editing areas being sub-editing areas. Each editing area is equipped with an independent layer controller, which manages all written data in that editing area. The conference system is equipped with a master layer linkage controller, which manages all individual layer controllers.

[0040] The embodiment of the present invention divides the control mode of the editing area (screen editing control mode) into two modes: main speaker control mode and sub-writer control mode. The main speaker can select the mode through the video screen of the main device, and the mode selection is controlled by the conference system as a whole.

[0041] The conference system receives the screen editing control mode selection instruction selected by the speaker through the video screen of the main device and determines the screen editing control mode. At this time, the screen editing control mode of the device of each participant is the same. Under different screen editing control modes, the video screen of each participant's device is controlled to display the corresponding editing area, and receives the editing instructions of each participant on the editing area of ​​his own device to realize editing of the corresponding editing area, so that the participants do not need to share an editing area. Each participant can view the content of different editing areas through his own device and write on the corresponding editing area, thereby improving the flexibility of video conference management. In addition, the speaker can also view all sub-screen areas and their contents through the main device to achieve the effect of multi-screen linkage.

[0042] Specifically, when the speaker needs to give a lecture, the speaker control mode is selected. In the speaker control mode, the video screens of the speaker's main device and all the audience's sub-devices are displayed as the main editing area. The speaker has the editing authority of the main editing area and can edit the main editing area through the main device. The audience only has viewing authority. The layer controller of the main editing area is turned on and the main editing area enters the editing state. At this time, all the writing data written by the speaker in the main editing area of ​​the main device is recorded. Specifically, each writing data formed from the time the pen is put down to the time it is lifted is recorded as a layer, and the information of the layer includes the writing data.

[0043] After the speaker finishes speaking, select the separate writing control mode. In the separate writing control mode, the screen video of all the listeners' sub-devices will be displayed as their corresponding sub-editing areas, and all listeners can write on the corresponding sub-editing areas. At this time, the layer controllers of all sub-editing areas are started and enter the editing state of the sub-editing areas. At this time, all the writing data written by the listeners on the corresponding sub-editing areas are recorded. Specifically, each writing data formed from the pen being put down to being lifted is recorded as a layer, and the information of the layer includes the writing data. The conference system will hide the main editing area in the video screen of the speaker's main device and display all sub-blackboard areas instead.

[0044] In an optional embodiment, the screen editing control mode further includes: an online control mode;

[0045] In the online control mode, all the video screens are controlled to display the main editing area and the written data on the main editing area and all the sub-editing areas and the written data on each sub-editing area; wherein, all editing areas can be edited through the main device, and the editing area includes the main editing area and all the sub-editing areas.

[0046] In an embodiment of the present invention, the screen editing control mode further includes an online control mode. In the online control mode, the main editing area and the sub-editing areas can interact with each other, and the presenter can edit all the editing areas through the main device.

[0047] For example, when the speaker needs to interact with the main editing area and the sub-editing area, the online control mode is selected. In the online control mode, the video screen of the listener's sub-device is displayed as the video screen of the speaker's main device. The content displayed on the video screen of the speaker's main device includes the main editing area and all sub-editing areas. For example, half of the video screen is the main editing area, and the other half is all sub-editing areas, as shown in Figure 2. In the online control mode, the layer controller of the main editing area and the layer controller of the corresponding sub-editing area are turned on at the same time. When the speaker writes on the video screen of the main device, the boundary position of the writing data is used to determine which editing area the writing data is on, and the writing data is recorded in the layer controller of the corresponding editing area. Specifically, the writing data formed from each time the pen is put down to the time it is lifted is recorded as a layer, and the information of the layer includes the writing data.

[0048] It is understandable that when the conference system receives the instruction to release the online control mode and re-enters other screen editing control modes, all writing data generated in the online control mode will continue to be retained in the corresponding layer controller.

[0049] In an optional embodiment, the video screen processing method further includes:

[0050] In the online control mode, when a drag trigger command inputted by the master device is detected, the target written data selected by the drag trigger command on the current editing area is copied, and the copied target written data is dragged from the current editing area to another editing area with the position of the target written data as a starting point, and a drag track is formed during the dragging process;

[0051] After the dragging is completed, the copied target writing data is pasted into another editing area, and the dragging track is deleted.

[0052] It is understandable that the presenter can drag across areas through the video screen of the main device. When the presenter needs to drag across areas (they can drag from the main editing area to the sub-editing area, or from the sub-editing area to the main editing area), they can click on the target writing data in the current editing area. The layer controller of the current editing area receives the drag trigger instruction, copies the target writing data, and then moves the copied target writing data along the drag trajectory of the presenter to form a drag effect. When the presenter drops the copied target writing data in another editing area, the layer controller of the other editing area immediately records and pastes the target writing data. The total layer linkage controller will delete the writing data that temporarily produces a drag effect due to dragging, as shown in Figure 3.

[0053] For example, when dragging the target writing data, you can also drag the layer where the target writing data is located. The presenter clicks on the target writing data in the current editing area, and the layer controller of the current editing area receives the drag trigger instruction, calculates the layer where the target writing data to be dragged is located, and immediately copies the layer. Then, the copied layer moves along the drag trajectory of the presenter to form a drag effect. When the presenter drops the copied layer in another editing area, the layer controller of the other editing area immediately records and pastes the information of the layer (target writing data). The total layer linkage controller will delete the writing data that temporarily produces a drag effect due to dragging.

[0054] In an optional embodiment, the target writing data includes: the shape of each writing data on the current editing area and the positional relationship between them.

[0055] It can be understood that the target writing data includes the shape of each writing data and the positional relationship between them, wherein each writing data formed from the time the pen is put down to the time it is lifted up will also be recorded as a layer.

[0056] For example, when the target writing data is located in multiple layers, multiple layers need to be dragged at the same time. The presenter can select multiple layers by selecting a box. The overall layer linkage controller repackages the shapes and positional relationships of the multiple layers to form a new layer, and drags the new layer to simultaneously drag the selected multiple layers to another editing area to complete the cross-area dragging of the target writing data.

[0057] In an optional embodiment, the video screen processing method further includes:

[0058] In the online control mode, a first zoom-in instruction input through the main device is received, the sub-editing area selected by the first zoom-in instruction is zoomed in to a first preset size, and all the video screens are controlled to display the sub-editing area zoomed in to the first preset size and the written data thereon and the main editing area and the written data thereon.

[0059] It can be understood that in the online control mode, the speaker can use the main device to select any sub-editing area among all the sub-editing areas and then zoom in. At this time, the video screens of all participants' devices display half of the main blackboard and half of the selected sub-editing area. This makes it more convenient for the speaker to edit the two editing areas in the video screen and drag across areas through the main device.

[0060] In an optional embodiment, the video screen processing method further includes:

[0061] In the online control mode, a second zoom-in instruction inputted through any of the sub-devices is received, the sub-editing area selected by the second zoom-in instruction is zoomed in to a second preset size, and the video screen of any of the sub-devices is controlled to display the sub-editing area zoomed in to the second preset size and the written data thereon; wherein, any of the sub-devices corresponds to the sub-editing area selected by the second zoom-in instruction, and the sub-editing area zoomed in to the second preset size displayed on the video screen of any of the sub-devices can be edited.

[0062] It is understood that in the online control mode, when the audience needs to edit their own sub-editing area, the audience can also zoom in on the corresponding sub-editing area and edit it through the sub-device to modify the written data in the zoomed sub-editing area. In this embodiment of the present invention, not only can the lecturer edit all editing areas through the main device, but the audience can also edit the corresponding sub-editing area through the sub-device, realizing free editing of the screen area.

[0063] In an optional embodiment, the video screen processing method further includes:

[0064] In any of the screen editing control modes, a third zoom-in instruction input through the main device is received, any sub-editing area selected by the third zoom-in instruction is zoomed in to a third preset size, and all the video screens are controlled to display the sub-editing area zoomed in to the third preset size and the written data thereon.

[0065] It is understandable that in any screen editing control mode, the presenter can zoom in on any sub-editing area through the main device so that the audience can clearly see the content to be displayed.

[0066] In an optional embodiment, the video screen processing method further includes:

[0067] In the main speaker control mode, receiving an editing instruction inputted through the main device, editing the main editing area, and obtaining written data on the main editing area;

[0068] In the separate writing control mode, receiving an editing instruction inputted through the sub-device, editing the corresponding sub-editing area, and obtaining writing data on the corresponding sub-editing area;

[0069] The editing instruction includes any one of the following or a combination thereof: a writing instruction, an erasing instruction, and a rollback instruction.

[0070] It can be understood that in the main speaker control mode, the speaker can edit the main editing area through the main device, and in the sub-writing control mode, the audience can edit the sub-editing area through the sub-device. Each audience can only edit his or her own sub-editing area.

[0071] It can be understood that the writing instruction can be used to write in the editing area, the erasing instruction can be used to erase the content written in the editing area, and the rollback instruction can be used to roll back the content written in the editing area to the state of the previous operation.

[0072] A video screen processing method provided by an embodiment of the present invention controls the video screens of all participants' devices to display the main editing area and the written data on the main editing area in the main speaker control mode, and controls the video screen of each sub-device to display the corresponding sub-editing area and the written data on the corresponding sub-editing area in the sub-writing control mode, and controls the video screen of the main device to display all the sub-editing areas and the written data on each sub-editing area, so that participants do not need to share one editing area, each participant can view the contents of different editing areas through his or her own device, and write on the corresponding editing area, thereby improving the flexibility of video conference management, and the main speaker can also view all sub-screen areas and their contents through the main device, thereby achieving the effect of multi-screen sharing.
