PPT documents can be embedded with text, images, videos, and more, and can be customized to enhance presentation quality. Multimedia presentations in the form of PPT are used in a variety of presentation situations.

[0003] Some exhibition halls often require multimedia presentations in the form of PPTs on large screens. These presentations are implemented using PPT software installed in large-screen display devices. Each PPT presentation requires the large-screen display device to open and play the PPT document in advance to ensure the screen's visual quality. This is typically performed in the exhibition hall, making it very cumbersome. Furthermore, PPT presentations must be performed in advance for each exhibit location. This is particularly time-consuming when there are many similar exhibit locations, as the playback mode must be set up individually, leading to low efficiency. Summary of the Invention

[0004] The embodiments of the present application provide a PPT document presentation control method, device, terminal, and storage medium to solve the problem in the prior art that presentation operation and maintenance are time-consuming and inefficient when performing PPT presentations on large-screen presentation equipment at multiple exhibition sites.

[0007] Marking the display status of each display screen according to the display status parameter to obtain marking information corresponding to the display screen;

[0008] When it is determined based on the tag information that at least one of the display images includes a first display image that matches the set large-screen demonstration effect, extracting the first display image;

[0009] The first display images are sequentially output to the large screen for display.

[0010] A second aspect of an embodiment of the present application provides a PPT document presentation control device, comprising:

[0011] an acquisition module, configured to, when the PPT software is identified from the terminal, acquire at least one display screen after the PPT software opens a PPT document and a display state parameter corresponding to each display screen, wherein the display state parameter is used to indicate a display control state of the PPT document in the PPT software;

[0012] a marking module, configured to mark the display status of each display screen according to the display status parameter, and obtain marking information corresponding to the display screen;

[0013] an extraction module configured to extract a first display picture matching a set large-screen presentation effect when it is determined that at least one of the display pictures includes the first display picture based on the marking information;

[0014] The output module is used to output the first display images in sequence to the large screen for display.

[0015] A third aspect of an embodiment of the present application provides a terminal, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method described in the first aspect when executing the computer program.

[0016] A fourth aspect of an embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method described in the first aspect are implemented.

[0033] It should be understood that the size of the serial numbers of each step in this embodiment does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of this application.

[0034] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0035] See also Figure 1 , Figure 1 This is a process of a PPT document presentation control method provided by the embodiment of the present application Figure 1 .like Figure 1 As shown, a PPT document presentation control method includes the following steps:

[0036] Step 101: When PPT software is identified from a terminal, at least one display screen and display status parameters corresponding to each display screen are obtained after the PPT software opens a PPT document.

[0037] The display status parameter is used to indicate the display control status of the PPT document in the PPT software.

[0038] The PPT software is, for example, the PPT software in Microsoft Office software or the PPT software in WPS.

[0039] The identification of PPT software can be performed by directly reading the local software installation information to determine whether the PPT software is installed in the computer, or by reading the default usage items of the PPT document in the terminal to determine whether there is a default installed PPT software.

[0040] At least one display screen is, for example, a display screen in the editable state after the PPT document is opened by PPT software, a display screen in the document preview state, a display screen during document editing, a playback display screen in the slide show state when the document is being projected, etc.

[0041] The display state parameters corresponding to the display screen include, for example, full-screen display parameters, non-full-screen display parameters, interface display parameters in an editable state, interface display parameters in a document projection state, and the like.

[0042] This scenario includes a large display screen and operating terminals (such as mobile phones, iPads, laptops, etc.).

[0043] The operating terminal comes with default PPT software and a PPT presentation control system for operating the default PPT software. The PPT presentation control system can identify the PPT software from the terminal, execute corresponding related operations, and establish a control connection with the large display screen.

[0044] Wherein, when the PPT software is identified from the terminal, before obtaining at least one display screen after the PPT software opens the PPT document and the display state parameters corresponding to each display screen, the method further includes:

[0045] When the PPT software is not recognized from the terminal, the PPT document playback video screen is set to be output to the large screen for display, and software installation prompt information is output.

[0046] In this process, when the PPT software is not recognized, before configuring the PPT presentation content on the large screen, the PPT document playback video screen will be output to the large screen for display, so as to avoid blank waiting time on the large screen, thereby improving the display effect of the large screen in the exhibition hall and the user viewing experience, and giving corresponding prompts.

[0047] Moreover, in an exhibition hall environment, the PPT presentation program in the PPT software can be designed as a startup item. Then, after the terminal is turned on, the full-screen presentation screen of the set PPT document can be directly entered. At this time, the display screen of the PPT document corresponding to the startup item in the PPT software can be obtained, and the display screen can be directly output to the large screen for display, so as to realize the self-starting screen at startup. There is no need to manually open the PPT software, and at the same time, before configuring the PPT presentation content on the large screen, there will be no blank waiting time on the large screen, thereby improving the display effect of the large screen in the exhibition hall and the user viewing experience.

[0048] Step 102 : Mark the display status of each display screen according to the display status parameter to obtain marking information corresponding to the display screen.

[0049] The marking information can be the marking information obtained by extracting key information from the display state parameters, or the marking information corresponding to the display state parameters can be obtained by matching the corresponding relationship between the display state parameters and the set marking characters, so as to realize the display state marking of each display screen.

[0050] Step 103 : based on the marking information, when it is determined that at least one of the display images includes a first display image that matches the set large-screen demonstration effect, extract the first display image.

[0051] Among them, when judging whether at least one display screen includes a first display screen that matches the set large-screen presentation effect based on the tag information, it can be achieved by judging whether the display control state of the PPT document indicated by the tag information in the PPT software is a document editing state or a full-screen display state.

[0052] When the display control state of the PPT document in the PPT software is the document editing state or the non-full-screen display state, it is determined that the target display screen corresponding to the mark information does not match the set large-screen display effect and does not meet the full-screen and normalized projection display requirements on the large screen.

[0053] When the display control state of the PPT document in the PPT software is a slide show state or a full-screen display state, it is determined that the target display screen corresponding to the mark information matches the set large-screen display effect, and meets the full-screen and normalized projection display requirements on the large screen.

[0054] That is, the set large-screen display effect requires that the display screen output to the large screen needs to be the PPT document in the slide show state or full-screen display state in the PPT software. At this time, the PPT document is played normally, and the corresponding display screen also meets the playback effect requirements of the large screen. In this way, the first display screen that matches the set large-screen presentation effect is selected and extracted from at least one display screen.

[0055] More specifically, in a specific implementation process, the process may include:

[0056] At least one of the display screens is associated with the tag information and stored to obtain a storage queue; the tag information is extracted from the storage queue in sequence, and based on each piece of the extracted tag information, whether the corresponding target display screen matches the set large-screen display effect is determined; if the judgment result is yes, the target display screen is determined to be the first display screen; and the first display screen is extracted from the storage queue.

[0057] That is, each display image and its corresponding tag information are associated and stored. This storage specifically involves data caching to obtain a corresponding data cache queue. When a group of display images is stored, centralized judgment processing is performed, or judgment processing is performed while caching to extract the first display image that matches the set large-screen presentation effect, and then sequentially transmit it to the large screen for display.

[0058] Wherein, judging whether the target display screen corresponding to each of the extracted mark information matches the set large-screen display effect specifically includes:

[0059] For each piece of marking information, when the display control state of the PPT document indicated by the marking information in the PPT software is a document editing state or a non-full-screen display state, determining that the target display screen corresponding to the marking information does not match the set large-screen display effect; or

[0060] For each of the tag information, when the display control state of the PPT document indicated by the tag information in the PPT software is a slide show state or a full-screen display state, it is determined that the target display screen corresponding to the tag information matches the set large-screen display effect.

[0061] This process automatically screens the PPT document display screens in the local PPT software in the terminal, selects the screens that meet the large-screen display requirements and outputs them in a remote control manner. In this way, a display screen that matches the set large-screen demonstration effect is selected from at least one display screen and output to the large screen for display, thereby ensuring the screen display effect of the PPT document on the large screen. At the same time, it eliminates the need for display operation and maintenance of the large screens displayed one by one in each exhibition point in the exhibition hall, realizes convenient remote terminal configuration and PPT display screen control, saves manpower and material resources, and improves efficiency.

[0062] Furthermore, after marking the display status of each display screen according to the display status parameter to obtain marking information corresponding to the display screen, the method further includes:

[0063] Based on the marking information, when it is determined that at least one of the display images includes a second display image that does not match the set large-screen demonstration effect, the second display image is discarded.

[0064] Here, unnecessary display images are discarded to save storage space and reduce interference from unnecessary display information.

[0065] In specific applications, the above processing process can be to obtain data on various playback interface states when the default PPT software in the operation terminal is playing, mark the obtained data according to the full-screen or editable playback state of the PPT page in the PPT software, temporarily cache these screen data and marking information, judge whether the marking information matches the desired playback effect of the currently set large screen, extract the screen data whose playback state is marked as matching the playback effect currently required by the display large screen, and transmit them to the display large screen for display in sequence, and discard other screen data.

[0066] Discarded screens include, for example, editable display screens and PPT switching screens in non-full-screen mode. This ensures that the screen that can be displayed on the large screen is always a perfect PPT playback screen, and that remote control such as editing and switching of the PPT played on the large screen can be achieved on the operation terminal without outputting the corresponding editing screen to the large screen for display.

[0067] Step 104: output the first display images in sequence to the large screen for display.

[0068] Through the above process, the overall presentation screen push process between a terminal and the large screen is realized, which improves the convenience of PPT presentation screen configuration and provides visitors with a perfect presentation screen.

[0069] In the embodiment of the present application, by automatically screening the PPT document display screens in the local PPT software in the terminal, the screens that meet the large-screen display requirements are selected and output in a remote control manner. In this way, a display screen that matches the set large-screen demonstration effect is selected from at least one display screen and output to the large screen for display, thereby ensuring the screen display effect of the PPT document on the large screen. At the same time, the display operation and maintenance of the large screen displayed at each exhibition point in the exhibition hall are eliminated, thereby realizing convenient remote terminal configuration and PPT display screen control, saving manpower and material resources, and improving efficiency.

[0070] The embodiments of the present application also provide different implementation methods of the PPT document presentation control method.

[0071] See also Figure 2 , Figure 2 This is a process of a PPT document presentation control method provided by the embodiment of the present application Figure 2 .like Figure 2 As shown, a PPT document presentation control method includes the following steps:

[0072] Step 201: When PPT software is identified from a terminal, at least one display screen after the PPT software opens a PPT document and display state parameters corresponding to each display screen are obtained.

[0073] The display status parameter is used to indicate the display control status of the PPT document in the PPT software.

[0074] The implementation process of this step is the same as the implementation process of step 101 in the aforementioned embodiment, and will not be repeated here.

[0075] Step 202 : Mark the display status of each display screen according to the display status parameter to obtain marking information corresponding to the display screen.

[0076] The implementation process of this step is the same as the implementation process of step 102 in the aforementioned embodiment, and will not be repeated here.

[0077] Step 203 : based on the marking information, when it is determined that at least one of the display images includes a first display image that matches the set large-screen demonstration effect, extract the first display image.

[0078] The implementation process of this step is the same as the implementation process of step 103 in the aforementioned embodiment, and will not be repeated here.

[0079] Step 204: extract target display configuration parameters corresponding to the set large-screen display effect from the display parameter configuration table.

[0080] The display parameter configuration table is configured with display configuration parameters required by the large screen under different screen display effects.

[0081] The display configuration parameters include, for example, the width, height, display ratio, display pixels, and image display position of the display screen.

[0082] Step 205 : configuring display parameters of the first display screen according to the target display configuration parameters, and outputting the first display screen to the large screen for display after the display parameter configuration is completed.

[0083] This process realizes adaptively configuring or rewriting the display parameters of the matching screen data according to the parameter configuration table.

[0084] The PPT demonstration control system captures the operating data of the default PPT software in the operation terminal, and rewrites the parameters of the operating data after capturing. The rewritten parameters are parameters that are compatible with the display effect of the large screen.

[0085] The parameters include, for example, the width, height, and position of the display screen, and the full screen or small screen display effect.

[0086] The large screen can display the picture according to the picture data rewritten by the display parameters, providing picture-in-picture or picture playback display at a set position and set background.

[0087] The system can also realize a non-full-screen PPT playback demonstration mode, which is convenient for combining with other presentation materials and realizing a picture-in-picture embedded PPT playback effect.

[0088] In the embodiment of the present application, by automatically screening the PPT document display screens in the local PPT software in the terminal, the screens that meet the large-screen display requirements are selected and output in a remote control manner. In this way, a display screen that matches the set large-screen demonstration effect is selected from at least one display screen and output to the large screen for display, thereby ensuring the screen display effect of the PPT document on the large screen. At the same time, the display operation and maintenance of the large screen displayed at each exhibition point in the exhibition hall are eliminated, thereby realizing convenient remote terminal configuration and PPT display screen control, saving manpower and material resources, and improving efficiency.
