Firstly, it should be noted that multi-screen linkage, also called multi-screen interaction, flying screen interaction and screen throwing interaction, is a novel display technology. The technology is mainly connected in a wireless mode such as Bluetooth, WIFI network and the like, and more than two display screens (such as mobile phones, PAD, televisions, touch screens, projectors and the like) are used for carrying out linkage display on multimedia display contents (such as pictures, characters, audio, video, software programs and the like) based on interactive application. Application scenarios for multi-screen linkage techniques include, but are not limited to, modern display presentations.

Common classifications of multi-screen linkages include screen mirroring, screen expansion, screen sharing, radar linkage, and the like. The screen mirroring means that the content of the main control screen is completely mirrored to other multimedia display equipment for synchronous display; the screen expansion is to respectively throw the content of the main control screen onto other display screens for collaborative display, and different display screens display different content; the screen sharing refers to the fact that the user can share the digital content and display the digital content in a split mode, and the content among the display screens can be dragged; the radar linkage is that a user touches the LOGO wall exhibition module, and the multimedia screen plays relevant propaganda contents.

The application advantages of the multi-screen linkage comprise borderless creative space display, and wider visual field; the multimedia split screen display has rich and clearer content; and innovative interesting interaction, and free control of multi-screen content.

In addition, the multi-screen linkage technology not only needs hardware support, but also needs application software support of a mobile phone end, a multi-screen interaction box and an intelligent television end.

FIG. 1 is a schematic diagram illustrating a multi-screen joint presentation according to an exemplary embodiment of the present application. The schematic diagram includes a plurality of associated display devices, as shown in fig. 1, in the multi-screen joint display, the plurality of display devices are arranged in different areas, wherein the display content on the slave display device is synchronous with the display content on the master display device, and after the display content on the master display device changes, the display content on the slave display device also changes, so as to ensure the use experience of a user, and in the multi-screen joint display scene, the display content on the slave display device can be the same as or different from the demonstration attention content on the master display device according to the content display mode. According to actual application requirements, the screen expansion is to respectively screen the content of the main control screen to other slave display screens for collaborative display, and the display content on the slave display equipment which is collaborative display is an associated main body with different content from the demonstration main body on the master display equipment. The embodiment of the application also does not limit the number and the position of the slave display devices, and can be set according to actual requirements.

FIG. 2 is a schematic diagram of an implementation environment for content presentation control during a multi-screen linked presentation process according to an exemplary embodiment of the present application. As shown in fig. 2, in the multi-screen linkage presentation process, an identifier corresponding to a scene to be presented input on the master display device 210 is acquired, and the identifier is sent to the content presentation control end server 230, so that a corresponding subject to be presented on the master display device 210 is determined according to the identifier by the server, and then a scheduling instruction is sent to a plurality of slave display devices 230 associated with the master display device 210 according to the subject to be presented on the master display device, so that a target subject matched with a content presentation mode of the slave display device 230 is presented on the slave display device 230 through the scheduling instruction, wherein the target subject comprises a mirror subject having the same content as the subject to be presented or an associated subject having different content from the subject to be presented.

The master display device 210 and the slave display device 230 shown in fig. 2 may be any terminal device supporting installation of navigation map software, such as a smart phone, a car-mounted computer, a tablet computer, a notebook computer, or a wearable device, but are not limited thereto. The multi-screen coordinated control end server 220 shown in fig. 2 is a control server, for example, may be an independent physical server, may be a server cluster or a distributed system formed by a plurality of physical servers, and may be 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, CDN (Content Delivery Network ), and basic cloud computing services such as big data and artificial intelligence platforms, which are not limited herein. The master display device 210 and the slave display device 230 may communicate with the multi-screen coordinated control terminal server 220 through a wireless network such as 3G (third generation mobile information technology), 4G (fourth generation mobile information technology), 5G (fifth generation mobile information technology), and the like, which is not limited in this regard.

The existing public lecture introduction scene is often realized by a host throwing a screen or using a shared desktop of an online conference, so that the lecture scene can only often use a screen with normal resolution to show the visitor lecture, the multi-screen synchronous linkage display content cannot be realized, and different display contents under the same demonstration scene cannot be displayed in a multi-screen linkage manner. Therefore, how to realize multi-screen synchronous linkage display of different display contents in the same demonstration scene is a technical problem that a person skilled in the art needs to continuously study.

The problems noted above have general applicability in a universal multi-screen joint display. To solve these problems, embodiments of the present application respectively propose a content presentation control method, a content presentation control apparatus, an electronic device, a computer-readable storage medium, and a computer program product, and these embodiments will be described in detail below.

Referring to fig. 3, fig. 3 is a flowchart illustrating a content presentation control method according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 2 and is specifically performed by the server 220 in the implementation environment. It should be understood that the method may be adapted to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is adapted are not limited by the present embodiment.

For example, as shown in fig. 1, in the multi-screen linkage system, corresponding to a plurality of display devices associated with each other, a plurality of display devices may be used to synchronously display a presentation body in the same presentation scene.

As shown in fig. 3, in an exemplary embodiment, the content presentation control method at least includes steps S310 to S330, which are described in detail as follows:

step S310, obtaining an identifier corresponding to a scene to be demonstrated, which is input on the main display device, and displaying a corresponding subject to be demonstrated on the main display device according to the identifier, wherein the subject to be demonstrated comprises a demonstration subject under the scene to be demonstrated.

Firstly, it should be noted that the main display device may be set according to actual application requirements, and any one or more display devices in the multi-screen combined system may be set as the main display device according to actual application requirements, where the main display device may be an electronic device with a display area, such as a smart phone, a vehicle-mounted terminal, a tablet computer, and a wearable device. Accordingly, the slave display device may be other display devices in the multi-screen unified system than the master display device.

The identification corresponding to the scene to be demonstrated is an identification for representing a demonstration subject resource corresponding to the scene to be demonstrated, wherein the identification corresponding to the scene to be demonstrated can be a file name corresponding to the scene to be demonstrated, a corresponding code, a corresponding identity identification, a corresponding keyword and the like for acquiring the identification information of the scene to be demonstrated.

According to the identification corresponding to the scene to be demonstrated, which is input on the main display device, the resource of the demonstration scene corresponding to the scene to be demonstrated can be scheduled from the storage area corresponding to the main display device according to the identification, wherein, in order to rapidly acquire the resource corresponding to the scene to be demonstrated, the resource information corresponding to the scene to be demonstrated can be stored on the main display device in advance, so that the demonstration main body corresponding to the scene to be demonstrated is scheduled according to the input identification corresponding to the scene to be demonstrated, and further, when the weak network environment or the network environment is bad, the corresponding main body to be demonstrated is directly taken out according to the storage area corresponding to the main display device.

In some possible embodiments, the corresponding main body to be demonstrated may be obtained from the server according to the identifier corresponding to the scene to be demonstrated input by the main display device, so that the main body to be demonstrated is displayed in the display area corresponding to the main display device.

Step S320, according to the main body to be demonstrated, a scheduling instruction is sent to a plurality of slave display devices associated with the master display device, wherein the scheduling instruction is used for acquiring the demonstration main body which is demonstrated on the plurality of slave demonstration devices under the scene to be demonstrated.

The demonstration bodies displayed on the plurality of slave demonstration devices in the multi-screen combined demonstration system are associated with the to-be-demonstrated bodies displayed on the master display device, so that scheduling instructions can be generated according to the demonstration bodies displayed on the master display device, wherein the scheduling instructions are used for acquiring the corresponding demonstration bodies displayed on the plurality of slave demonstration devices in the to-be-demonstrated scene.

The presentation main body on the slave display device can be preset and stored in a corresponding storage area of the slave display device, and the corresponding presentation main body on the slave display device can be taken out from the corresponding storage area according to the scheduling instruction. That is, in order to avoid that the slave display device needs to cache the presentation body associated with the master display device, or that the master display device needs to send the corresponding presentation body to the slave display device to occupy excessive bandwidth resources, so that the loading of the presentation body is too slow, and the synchronization time delay of multi-screen linkage is larger.

After the main display device determines the main body to be demonstrated, a scheduling instruction can be generated according to the main body to be demonstrated and sent to the plurality of auxiliary display devices, and after the scheduling instruction is received from the auxiliary display devices, the demonstration main body corresponding to the required demonstration is obtained from the cached scene resource to be demonstrated according to the instruction of the scheduling instruction.

Step S330, a content display mode of the slave display device is obtained, and a target subject matched with the content display mode is displayed on the slave display device according to a scheduling instruction, wherein the target subject comprises a mirror image subject with the same content as the subject to be demonstrated or an association subject with different content from the subject to be demonstrated.

The content display mode of the slave display device is a content display mode corresponding to the slave display device under the multi-screen linkage system, that is, the slave display device plays a role in the multi-screen linkage, and then a target subject matched with the content display mode can be displayed on the slave display device according to a scheduling instruction generated based on the subject to be displayed on the master display device. The target subject may be a mirror subject having the same content as the subject to be demonstrated displayed on the main display device or an associated subject having different content from the subject to be demonstrated displayed on the main display device.

In an exemplary embodiment, in the multi-screen linkage system, the content display mode of the slave display device may be a mode of expanding a screen, and the method is that scheduling instructions corresponding to the same mirror image body of the content of the main body to be demonstrated or different content association bodies of the main body to be demonstrated on the master display device are sent to the plurality of slave display devices.

For example, if the content display mode of the slave display device characterizes that the "role" of the slave display device in the multi-screen linkage system is to display the same presentation subject content as that of the master display device, the mirror image subject same as that of the master display device can be obtained from the storage area corresponding to the slave display device according to the scheduling instruction; if the content display mode of the slave display device indicates that the role of the slave display device in the multi-screen linkage system is to display an associated subject different from the content of the demonstration subject of the master display device, the demonstration subject different from the content of the demonstration subject of the master display device can be obtained from the storage area corresponding to the slave display device according to the scheduling instruction.

In the embodiment, the main body to be demonstrated is determined through the identification corresponding to the scene to be demonstrated, the loading time of the scene to be demonstrated is shortened, and the target main body matched with the content demonstration mode and tuned on the slave display device is obtained through the dispatching instruction, so that the bandwidth resources occupied by the target main body to the slave display device are avoided, the time required by loading the target main body from the display device is prolonged, the target main body matched with the target main body on the main body to be demonstrated according to the content demonstration mode of the slave display device, different demonstration main bodies under the same demonstration scene are synchronously demonstrated by multiple screens, and the use experience of a user is improved.

Further, based on the above embodiment, referring to fig. 4, in one exemplary embodiment provided in the present application, the specific implementation process of obtaining the content exhibition mode of the slave display device and exhibiting, according to the scheduling instruction, the target subject matched with the content exhibition mode on the slave display device may further include step S410 and step S420, which are described in detail below:

step S410, determining identity information of the slave display device based on the content presentation mode of the slave display device;

step S420, the target subject matched with the identity information is displayed on the slave display device according to the scheduling instruction.

In the above embodiments, the identity information of the slave display device may be determined according to the content presentation mode of the slave display device, that is, different slave display devices have different identity information in the multi-screen linkage system and play different "roles" in the multi-screen linkage system, so that the identity information of the slave display device may be determined according to the content presentation mode of the slave display device.

For example, the identity information of the slave display device may be according to the account information logged in on the client side of the slave display device, for example, if the account information logged in on the client side of the slave display device characterizes that the slave display device is a mirror image slave display device with the same content as the master display device, a mirror image subject with the same content as the subject to be demonstrated of the master display device may be acquired and displayed on the mirror image display device; if the account information registered on the client side of the slave display device is standard, the slave display device is associated slave display device which is different in content of the master display device, an associated body which is different in content from the body to be demonstrated of the master display device can be obtained and displayed on the associated slave display device.

For example, the content presentation mode of the slave display device may be determined according to the physical location information corresponding to the slave display device, the terminal attribute information corresponding to the slave display device, the number information corresponding to the slave display device, the size of the display area corresponding to the slave display device, the identification information of the slave display device, and the like, and the identity information of the slave display device may be determined according to the content presentation mode.

For example, the content presentation mode of the slave display device may include content presented on a display area corresponding to the slave display device, such as a mirror image body presenting the same content as a presentation body of the master display device, an associated body presenting a different content than the presentation body content of the master display device, a shard body presenting a portion of the presentation body content with the master display device, and so forth.

In the embodiment, the target main body matched with the identity information of the target main body is displayed on the slave display device according to the scheduling instruction, so that larger network bandwidth consumed in transmission of the content to be displayed when the target main body is synchronously shared with the content to be displayed of the master display device is avoided, the loading time of the slave display device to the target main body is shortened, and the use experience of a user is improved.

Further, based on the above embodiment, referring to fig. 5, in one exemplary embodiment provided in the present application, the specific implementation process of the content presentation control method may further include step S510 and step S520, which are described in detail below:

step S510, if the identity information characterizes that the slave display device is a first slave display device which is synchronous with the content of the master display device, displaying a mirror image main body with the same content as the main body to be demonstrated on the first slave display device according to the scheduling instruction.

Specifically, if the identity information of the slave display device characterizes that the slave display device is a first slave display device synchronous with the display content of the master display device in the multi-screen linkage system, a mirror image main body with the same content as the main body of the device to be demonstrated on the master display device can be displayed on the first slave display device according to the scheduling instruction.

For example, if the slave display device is represented by the first slave display device synchronous with the display content of the master display device according to the identity information corresponding to the slave display device, for example, the first slave display device may determine that the target subject to be displayed by the first slave display device should be the same as the content of the subject to be displayed on the master display device for a "audience role" under the theme of multi-person lecture or under the introduction of products, so that the target subject same as the content of the subject to be displayed on the master display device can be obtained from the storage area corresponding to the first slave display device for displaying.

In step S520, if the identity information characterizes that the slave display device is a second slave display device that is not synchronized with the content of the master display device, the associated subject having different content from the subject to be demonstrated is displayed on the second slave display device according to the scheduling instruction.

Specifically, if the identity information of the slave display device characterizes that the slave display device is a second slave display device which is not synchronous with the content of the master display device, that is, the target subject displayed on the second slave display device is different from the content of the subject to be demonstrated on the master display device, the second slave display device can be a display device for assisting the master display device in scene demonstration, so that the content of the subject demonstrated on the second display device and the content of the demonstration subject demonstrated on the master display device can be related, but the demonstrated content is different. Further, after determining that the slave display device is the second slave display device, an association body different from the content of the presentation body on the master display device may be obtained from a storage area corresponding to the second slave display device according to the scheduling instruction.

For example, as shown in fig. 6, if the slave display device is characterized as a second slave display device that is not synchronized with the content of the master display device according to the identity information corresponding to the slave display device, for example, the second slave display device may be an "assistant role" in multi-screen coordinated control such as under a multi-person lecture theme, under a product introduction, or under an offline theme meeting, and the like, it may be determined that a target subject to be displayed by the second slave display device is displayed by an association subject that is different from the content of the presentation subject displayed on the master display device, where the association subject may be a subject associated with the content of the presentation subject on the target display device, or may be a subject associated with the content of the presentation scene.

In this embodiment, according to the difference of identity information, the mirror image main body with the same content as the main display device or the association main body with different content as the main display device is displayed on the slave display device, so that different demonstration main bodies are displayed by a plurality of display devices in the same demonstration scene, flexibility and intelligence of multi-screen linkage display are improved, and a multi-screen linkage demonstration effect is improved.

Further, based on the above embodiment, referring to fig. 7, in one exemplary embodiment provided in the present application, the specific implementation process of the content presentation control method may further include the following step S710 and step S720, which are described in detail below:

Step S710, if the identity information characterizes that the slave display device is a second slave display device which is not synchronous with the content of the master display device, acquiring the position information corresponding to the second slave display device;

and step S720, displaying a target subject matched with the position information on the second slave display device according to the scheduling instruction, wherein the target subject comprises a derivative subject associated with the subject content to be demonstrated.

In the above embodiment, if the slave display device is characterized as a second slave display device unsynchronized with the content of the master display device according to the identity information corresponding to the slave display device, the position information corresponding to the second slave display device is obtained; the position information corresponding to the second slave display device can be obtained according to the wireless connection mode of the second slave display device corresponding to the multi-screen linkage system, and the position information corresponding to the second slave display device can also be reported through the second slave display device.

The location information may include physical address information of the second slave display device, wherein the physical address information is an identifier for uniquely identifying each device in the network. It is typically used in local area networks to ensure that data packets are properly sent to the target device. The physical address, also called MAC address, is 48 bits (6 bytes) in length, typically represented by 12 hexadecimal numbers. For example, D0-17-C2-8B-12-9F is a MAC address (local area network address). The MAC address consists of two parts: the first 6 hexadecimal digits are assigned by the IEEE (institute of electrical and electronics engineers) to the network hardware manufacturer, and the last 3 hexadecimal digits are the serial number of a certain network product (such as a network card) manufactured by the manufacturer. Since the number of each manufacturer is unique, the MAC address of the network device produced by each manufacturer is also unique. All data packets transmitted in the network will contain the physical addresses of the sender and receiver to ensure that the data is properly sent to the destination device.

For example, the function corresponding to the second slave display device in the multi-screen linkage system may be determined according to the physical address information of the second slave display device, so as to determine, according to the physical address information of the second slave display device, a target subject displayed on the second slave display device, where the target subject includes a derivative subject associated with a subject to be demonstrated on the master display device, for example, the derivative subject may be obtained by performing derivative calculation according to the corresponding subject to be demonstrated on the master display device.

For example, in some possible embodiments, the position information of the second slave display device may further include a relative position relationship between the second slave display device and the master display device, or a relative position relationship between the second slave display device and the first slave display device, and further obtain a target subject displayed on the second slave display device according to the relative position relationship between the master display device of the second slave display device or the relative position relationship between the second slave display device and the first slave display device, where the target subject includes a derivative subject associated with the subject content to be demonstrated on the master display device. For example, the subject to be demonstrated on the master display device is a "new release meeting", and then the derivative subject on the second slave display device may be a description corresponding to the new meeting, a usage scenario, or the like, associated with the subject to be demonstrated shown on the master display device.

In this embodiment, a target main body matched with physical address information or relative position information from the main display device is displayed on the slave display device which is not synchronous with the content of the main display device according to the call instruction, so that a plurality of display devices can display different demonstration main bodies in a linkage manner, and flexibility and intelligence of multi-screen linkage are improved.

Further, based on the above embodiment, referring to fig. 8, in one exemplary embodiment provided in the present application, after the content display mode of the slave display device is obtained and the target subject matched with the content display mode is displayed on the slave display device according to the scheduling instruction, the specific implementation method of the content display control method further includes step S810 and step S820, which are described in detail below:

step S810, obtaining a target display size corresponding to a target main body, wherein the target display size is a display size corresponding to the target main body on main display equipment;

step S820, the resolution corresponding to the slave display device is acquired, and the target view position of the target subject corresponding to the slave display device is determined based on the resolution and the target display size.

Specifically, as shown in fig. 9A, after determining the target subject displayed on the slave display device, a target display size corresponding to the target subject may be obtained, where the target display size may be a display size corresponding to the target subject when displayed on the master display device. That is, as shown in fig. 9A, the hatched box in the figure is a display size indicating that the target subject to be presented corresponds to when presented on the main display device, and the display size of the target subject can be noted as: the long side is m, and the short side is n.

And then obtaining the resolution corresponding to the display device, wherein the resolution determines the number of pixels displayed on the screen, and the higher the resolution is, the finer and finer the display effect is in general. In the case of the same screen size, the higher the resolution, the smaller the dot pitch, and the finer the image. The display size, which is commonly referred to as the diagonal length of the screen, determines the range over which the display can display content. The larger the display size, the more content can be displayed with the same resolution. Thus, the resolution and the display size are interrelated, which together determine the display quality and the effect of the display. In selecting a display, it is necessary to select an appropriate resolution and display size according to actual requirements.

And further determining the corresponding target visual field position of the target body on the slave display device according to the resolution corresponding to the slave display device and the target display size corresponding to the target body displayed on the slave display device.

In this embodiment, the target view position of the target main body on the slave display device can be adjusted according to the target display size of the target main body and the resolution of the slave display device, so as to achieve the slave display device adapting to various aspect ratio resolutions, full screen is paved on the picture, white left on the picture is avoided, the picture is not stretched or deformed, the viewing experience of the user is improved, and the visual effect of multi-screen linkage is ensured.

Further, based on the above embodiment, referring to fig. 10, in an exemplary embodiment provided in the present application, the specific implementation process of determining, based on the resolution and the target display size, the target subject' S corresponding target field of view position on the slave display device may further include step S1010 and step S1020, which are described in detail below:

step S1010, determining an initial display size corresponding to the slave display device based on the resolution, wherein the initial display size is a picture display size of the slave display device under an initial view angle;

in step S1020, the target view angle of the target subject on the slave display device is adjusted based on the initial display size and the target display size to determine the corresponding target view position of the target subject on the slave display device based on the target view angle.

As shown in fig. 9B, the slave display device may be determined to correspond to an initial display size according to a resolution corresponding to the slave display device, and as shown in fig. 9B, the slave display may be determined to correspond to a screen display size at an initial view angle according to a resolution corresponding to the slave display device. And the target visual field position corresponding to the target main body on the slave display device can be adjusted according to the initial display size corresponding to the slave display device and the target display size corresponding to the target main body displayed on the slave display device.

For example, as shown in fig. 9C, the view angle in the scene may be dynamically adjusted according to the current resolution and the picture proportion, where a hatched box indicates a target display size corresponding to the target subject, and is denoted as: the long side is m, and the short side is n. When the distance from the initial view position of the display device to the target subject is d, and then the corresponding picture display size is formed according to the initial view angle field of the display device, the long side of the picture display size is denoted as y, the short side is denoted as x, and when the display area of the display device is unchanged, since y and x are fixed values, it can be assumed that the target subject has a target view angle q on the display device, and the distance from the picture display area is d, when the view angle of the distance from the view position to the subject content is unchanged and the view angle becomes smaller, the focus of the view angle to a more central position is equivalent, and then the target subject is also enlarged, and even the picture display size under the initial view angle of the display device is supported, and further the viewing experience is poor. In this embodiment, a reasonable target field of view position may be calculated so as to avoid the target subject from bracing the display area of the display device from the display device.

Illustratively, according to the dimensions corresponding to the target display dimensions based on the above-described slave display area of the display device and the target subject, a calculation process may be obtained,

when (when)When the screen is broken, the user can judge that the screen is broken more easily than left and right. Thus, from the geometric relationships in fig. 9B and 9C, it can be derived that:

and then (I)>/>

When (when)When we can tell that the left and right of the subject content is easier to break the screen than up and down, we choose +.>Maintaining the preset ratio, the geometric relationship in fig. 9B and 9C may be derived:

wherein (1)>

Therefore, the most suitable view angle q can be calculated according to screens with different resolutions, the camera can ensure that a suitable view field is obtained, so that main body contents can be centrally displayed on different screens, the display proportion is kept consistent, the user can enjoy consistent visual experience on different devices, a picture which is clearer and more reasonable than a scheme of screen throwing and the like can be obtained on a high-resolution screen, in addition, the phenomenon of white left can not occur on the screen up and down or left and right by means of the background in a sky box even if the screens with different length-width ratios are used.

In this embodiment, the target viewing angle of the target main body in the slave display device is adjusted according to the initial display size of the slave display device and the target display size of the target main body, so that the slave display device can adapt to screens with various aspect ratio resolutions, full screen is paved on the screen, white left on the screen can not occur, the screen can not be stretched or deformed, the viewing experience of a user is improved, and the visual effect of multi-screen linkage is ensured.

Further, based on the above embodiment, referring to fig. 11, in one exemplary embodiment provided in the present application, the specific implementation process of the content presentation control method may further include step S1110 and step S1120, which are described in detail below:

In step S1120, the display content corresponding to the slave display device is adjusted based on the synchronization variable modification policy, where the display content includes the target subject displayed on the slave display device and the target field of view position corresponding to the target subject on the slave display device.

The main body change instruction to be demonstrated can be triggered on the main display device by acquiring the main body change instruction to be demonstrated, for example, a user can trigger the main body change instruction to be demonstrated on the main display device in the multi-screen linkage system by touching, inputting, displaying and the like, and further, the change parameters of the preset synchronous variable related to the main body content to be demonstrated on the main display device can be determined according to the main body change instruction to be demonstrated, specifically, the preset synchronous variable comprises the synchronous variable between the main body to be demonstrated and the target body demonstrated on the main display device, which are preset, wherein the synchronous variable can be variables such as the content of the main body to be demonstrated, the position of the main body to be demonstrated in the display area, the reduction and amplification of the main body to be demonstrated, the visual field position of the main body to be demonstrated and the like.

For example, when detecting a preset variable transmission change related to the content of the main body to be demonstrated on the master display device, a synchronous variable change policy of the corresponding slave display device needs to be generated, so as to adjust the display content corresponding to the target main body on the slave display device according to the synchronous variable change policy.

If the main display device detects that the main display device switches to the main display device, the main display device generates a corresponding synchronous variable change strategy according to the main display device, and sends the synchronous variable change strategy to the auxiliary display device, and further displays a target main body corresponding to the content display mode on the auxiliary display device according to the synchronous variable change strategy and the content display mode corresponding to the auxiliary display device, wherein the target main body can be a mirror image main body with the same main display device content as the main display device content to be displayed, or can be a related main body with different main display device content to be displayed.

And if the identity information of the slave display equipment characterizes that the slave display equipment and the master display equipment are first slave display equipment synchronous with the content of the master display equipment, displaying a target subject which is the same as the content of other demonstration subjects on the master display equipment on the first slave display equipment according to the synchronous variable change strategy so as to ensure that the synchronization of the first slave display equipment and the pictures displayed on the master display equipment is consistent.

In this embodiment, after the synchronization frame related to the content of the demonstration main body on the master display device is sent and changed, a corresponding synchronization variable change strategy is generated and sent to the slave display device.

Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the implementation process of the content presentation control method may further include the following steps, which are described in detail below:

and if the content display mode of the slave display equipment is a free browsing mode, displaying browsing content matched with the free browsing mode on the slave display equipment according to a scheduling instruction, wherein the browsing content comprises all demonstration main bodies corresponding to the scene to be demonstrated.

Specifically, the slave display device may also select a free browsing mode, in the free browsing mode of the slave display device, a target subject displayed on the slave display device may not change synchronously with a subject to be demonstrated on the master display device, after receiving a scheduling instruction generated according to the subject to be demonstrated displayed on the master display device, all presentation resources of a presentation scene corresponding to the subject to be demonstrated may be obtained according to the scheduling instruction, where the presentation resources include pictures, animations and presentation resources used for presenting the presentation scene, and the slave display device may freely browse all the presentation resources such as pictures, animations and videos in the presentation scene corresponding to the subject to be demonstrated on the master display device, and when detecting that a preset synchronous variable related to the content of the presentation subject to be demonstrated on the master display device changes, the target subject displayed on the slave display device does not change along with the preset synchronous variable, and further the slave display device may freely browse all the presentation resources of the presentation scene corresponding to the subject to be demonstrated on the master display device.

The method includes that after the slave display device is characterized to be in a free browsing mode according to the content display mode of the slave display device, the demonstration resources of the demonstration scenes corresponding to the slave display device are taken out from the internal storage area corresponding to the slave display device according to the scheduling instruction generated by the main to-be-demonstrated body displayed on the master display device, that is, the demonstration resources of the demonstration scenes corresponding to the main to-be-demonstrated body are stored in the internal storage area of the slave display device in advance, and further, the corresponding demonstration resources can be directly obtained according to the scheduling instruction, so that the situation that the slave display device needs to load the demonstration resources corresponding to the to-be-demonstrated scene for a long time in a weak network environment is avoided.

For example, in some possible embodiments, the master display device and the slave display device each store all presentation resources corresponding to the scene to be presented in the corresponding internal storage area in advance, and when receiving the corresponding scheduling instruction, directly call out the corresponding presentation body from the internal storage area of the master display device and the slave display device, so that the occupation of a large bandwidth to load the corresponding presentation body is avoided.

In this embodiment, the slave display device may freely browse the resources of the to-be-displayed scene corresponding to the to-be-displayed main body on the current master display device, and obtain the to-be-displayed scene through the scheduling instruction, so that the loading speed of the to-be-displayed resource on the slave display device is improved, and the local video in the slave display device is actually played, so that lossless playing can be performed, and even if there is network fluctuation, the client playing video is not affected, and the lossless playing of the to-be-displayed scene can be achieved, so that the viewing experience of the user is improved.
