[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] Referring to Figure 1 , Figure 1 is a flowchart of a video screen processing method provided by an embodiment of the present application, and the video screen processing method comprises the following steps.

[0034] S1, a screen editing control mode selected by a master device is acquired; wherein the master device is a device of a main speaker, and the screen editing control mode comprises a main control mode and a subwriting control mode;

[0035] S2, in the main control mode, a video screen of a device of each participant is controlled to display a main editing area and writing data on the main editing area; wherein the main editing area can be edited through the master device, and the participant comprises the main speaker and a listener;

[0036] S3, in the subwriting control mode, a video screen of each sub device is controlled to display a corresponding sub editing area and writing data on the corresponding sub editing area, and a video screen of the master device is controlled to display all the sub editing areas and writing data on each sub editing area; wherein the sub device is a device of the listener, and the corresponding sub editing area can be edited through the sub device.

[0037] It can be understood that the participants are divided into a main speaker and a listener, and each participant's device is equipped with an independent editing area, the device of the main speaker is a master device, the editing area of the main speaker is a master editing area, the device of the listener is a slave device, and the editing area of the listener is a slave editing area. Each editing area is equipped with an independent layer controller, which can manage all writing data of the corresponding editing area, and the conference system is equipped with a total layer linkage controller, which can manage all single layer controllers.

[0038] The control mode (screen editing control mode) of the editing area in the embodiment of the application is divided into two modes, a main speaker control mode and a separate writing control mode. The main speaker can select the mode through the video screen of the master device, and the mode selection is controlled by the conference system as a whole.

[0039] The conference system receives the screen editing control mode selection instruction selected by the main speaker through the video screen of the master device, determines the screen editing control mode, and at this time, the screen editing control mode of the device of each participant is the same. In different screen editing control modes, the video screen of the device of each participant is controlled to display the corresponding editing area, and the editing instruction of each participant on the editing area of the device is received, the corresponding editing area is edited, so that the participants do not need to share an editing area, each participant can watch the content of different editing areas through the device, and write on the corresponding editing area, improving the flexibility of video conference management, and the main speaker can also watch all sub-screen areas and their contents through the master device, realizing the effect of multi-screen linkage.

[0040] Specifically, when the main speaker needs to speak, the main speaker control mode is selected. In the main speaker control mode, the video screen of the master device of the main speaker and the video screen of the slave device of all listeners are displayed as the master editing area, the main speaker has the editing permission of the master editing area, can edit the master editing area through the master device, and the listeners only have the watching permission. The layer controller of the master editing area is turned on, and the editing state of the master editing area is entered, at this time, all writing data written by the main speaker on the master editing area of the master device are recorded, specifically, one writing data record formed by each time of pen down to pen up is a layer, and the information of the layer includes the writing data.

[0041] After the main speaker finishes speaking, a split-writing control mode is selected. In the split-writing control mode, the screen video of the sub-devices of all the listeners is displayed as a corresponding sub-editing area, and all the listeners can write on the corresponding sub-editing area. At this time, the layer controller of all the sub-editing areas is started, and the editing state of the sub-editing area is entered. At this time, all the writing data of the listeners on the corresponding sub-editing area is recorded. Specifically, one writing data formed by each time of pen-down to pen-up is recorded as a layer, and the information of the layer includes the writing data. The conference system hides the main editing area in the video screen of the main device of the main speaker, and displays all the sub-blackboard areas.

[0042] In an optional embodiment, the screen editing control mode further includes an online control mode.

[0043] In the online control mode, all the video screens control the display of the main editing area and the writing data on the main editing area, and the display of all the sub-editing areas and the writing data on each sub-editing area. Through the main device, all the editing areas including the main editing area and all the sub-editing areas can be edited.

[0044] In the embodiment of the application, the screen editing control mode further includes an online control mode. In the online control mode, the main editing area and the sub-editing area can interact, and the main speaker can edit all the editing areas through the main device.

[0045] For example, when the main 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 sub-devices of the listeners is displayed as the video screen of the main device of the main speaker. The content displayed by the video screen of the main device of the main speaker includes the main editing area and all the sub-editing areas, for example, half of the video screen is the main editing area, and the other half is all the sub-editing areas, as shown in FIG. 6. 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 started at the same time. When the main speaker writes on the video screen of the main device, according to the boundary position of the writing data, it is judged that the writing data is on which editing area, and the writing data is recorded to the layer controller of the corresponding editing area. Specifically, one writing data formed by each time of pen-down to pen-up is recorded as a layer, and the information of the layer includes the writing data.

[0046] It can be understood that when the conference system receives the online control mode release instruction and reenters other screen editing control modes, all the writing data generated in the online control mode will be continuously retained in the corresponding layer controller.

[0047] In an alternative embodiment, the video screen processing method further comprises:

[0048] In the online control mode, when a drag trigger instruction input by the host device is detected, target writing data on the current editing area selected by the drag trigger instruction is copied, and the copied target writing data is dragged from the current editing area to another editing area with the position of the target writing data as a starting point, and a drag track is formed during the dragging;

[0049] After the dragging ends, the copied target writing data is pasted to the other editing area, and the drag track is deleted.

[0050] It can be understood that the host speaker can perform cross-region dragging through the video screen of the host device. When the host speaker needs to perform cross-region dragging (the main editing area can be dragged to the sub-editing area, or the sub-editing area can be dragged to the main editing area), the target writing data in the current editing area can be clicked, 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 track of the host speaker to form a drag effect. When the host speaker 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 deletes the writing data temporarily generated due to the dragging to form the drag effect, as shown in FIG. 8. Figure 3

[0051] For example, when the target writing data is dragged, the layer in which the target writing data is located can also be dragged. The host speaker clicks the target writing data in the current editing area, the layer controller of the current editing area receives the drag trigger instruction, calculates the layer in which the target writing data to be dragged is located, immediately copies the layer, and then moves the copied layer along the drag track of the host speaker to form a drag effect. When the host speaker drops the copied layer in another editing area, the layer controller of the other editing area immediately records and pastes the information (target writing data) of the layer. The total layer linkage controller deletes the writing data temporarily generated due to the dragging to form the drag effect.

[0052] In an alternative embodiment, the target writing data comprises the shape of each writing data and the positional relationship therebetween on the current editing area.

[0053] It can be understood that the target writing data comprises the shape of each writing data and the positional relationship therebetween, wherein each writing data formed by pen-down to pen-up is recorded as a layer. ​

[0054] For example, when the target writing data is located in multiple layers, the multiple layers need to be dragged simultaneously, the presenter can select the multiple layers by framing, the total layer linkage controller re-packs the shape and position relationship of the multiple layers to form a new layer, and drags the new layer to drag the framed multiple layers to another editing area to complete the cross-region dragging of the target writing data.

[0055] In an optional embodiment, the video screen processing method further includes:

[0056] In the online control mode, a first zoom-in instruction input by the master device is received, a sub-editing area selected by the first zoom-in instruction is zoomed in to a first preset size, and all video screens of all the sub-editing areas and writing data thereon and the master editing area and writing data thereon are controlled to be displayed in the first preset size.

[0057] It can be understood that in the online control mode, the presenter can zoom in on any sub-editing area through the master device, and at this time, the video screens of all the devices of the participants display one half of the master blackboard and one half of the selected sub-editing area, which is more convenient for the presenter to edit the two editing areas in the video screens through the master device and to drag across the regions.

[0058] In an optional embodiment, the video screen processing method further includes:

[0059] In the online control mode, a second zoom-in instruction input by any of the sub-devices is received, a sub-editing area selected by the second zoom-in instruction is zoomed in to a second preset size, and a video screen of the any of the sub-devices is controlled to display the sub-editing area zoomed in to the second preset size and writing data thereon; the 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 the any of the sub-devices can be edited.

[0060] It can be understood that in the online control mode, when the listener needs to edit the sub-editing area of the listener, the listener can also zoom in on and edit the corresponding sub-editing area through the sub-device to modify the writing data of the zoomed-in sub-editing area. In the embodiment of the application, not only the presenter can edit all the editing areas through the master device, but also the listener can edit the corresponding sub-editing area through the sub-device, so that the editing of the screen area is free.

[0061] In an optional embodiment, the video screen processing method further includes:

[0062] In any of the screen editing control modes, a third zoom-in instruction input by the host device is received, any of the sub-editing areas 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 and the writing data thereon zoomed in to the third preset size.

[0063] It can be understood that in any of the screen editing control modes, the host can zoom in any of the sub-editing areas by the host device, so that the audience can clearly view the content to be displayed.

[0064] In an optional embodiment, the video screen processing method further comprises:

[0065] In the host control mode, an editing instruction input by the host device is received, the main editing area is edited according to the editing instruction, and writing data on the main editing area is obtained;
