Description

Technical Field

[0001] This invention relates to the field of real-time content projection and interactive annotation technology, and more specifically, to a method for real-time projection and interactive annotation of meeting content in an ultra-high-definition display system. Background Technology

[0002] In the field of conference collaboration and information sharing, ultra-high-definition display systems have become an important support for enterprises and institutions to conduct efficient meetings due to their advantages of high resolution and high definition visual presentation. Real-time projection of meeting content and interactive annotation technology are the core application links of ultra-high-definition display systems.

[0003] Existing technologies for real-time projection and interactive annotation of meeting content are mostly used in small and medium-sized internal meetings and routine business reports. These scenarios have relatively basic requirements for information accuracy and interactive relevance. However, in complex scenarios such as large-scale meetings, cross-departmental collaborative meetings, and technical seminars adapted to ultra-high-definition display systems, existing technologies have obvious shortcomings. Existing technologies do not divide dedicated interactive areas according to the differences in the content of meeting documents. Image files and video files share a unified interactive entry point, which easily leads to chaotic piling up within member interactions. Furthermore, there is a lack of a mechanism for summarizing and filtering the core content after interaction. A large amount of redundant information fills the meeting process, which not only increases the cost of information filtering for members but may also dilute the key topics of the meeting. Therefore, a method for real-time projection and interactive annotation of meeting content for ultra-high-definition display systems is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a method for real-time projection and interactive annotation of meeting content in an ultra-high-definition display system, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a method for real-time projection and interactive annotation of meeting content in an ultra-high-definition display system is provided, including the following steps:

[0006] S1. Set the upload conditions for the ultra-high-definition display system, and verify the eligibility of the uploaded meeting files based on the upload conditions;

[0007] S2. The meeting documents are projected into the screen in real time through an ultra-high-definition display system. Interactive areas are divided according to the differences in the content of the meeting documents. Meeting members upload interactive content through the corresponding interactive areas, and the interactive content in the interactive areas is analyzed in the area minutes.

[0008] S3. Record meeting presentations and generate meeting minutes. At the same time, perform correlation coefficient analysis on the regional minutes in the interactive area based on the corresponding meeting minutes, and filter and retain the regional minutes based on the correlation coefficient.

[0009] S4. Analyze the quick annotation operations by combining the retained regional minutes with the corresponding interactive areas, then display the quick annotation operations to the meeting management terminal based on the correlation coefficient, and optimize the interactive areas based on the quick annotation operations fed back by the meeting management terminal.

[0010] S5. Record historical quick annotation operations and obtain the meeting members corresponding to the historical quick annotation operations. At the same time, analyze the presentation duration of the completed interaction areas based on the meeting duration. Based on the presentation duration of the interaction areas, add an additional correlation coefficient to the meeting members corresponding to the historical quick annotation operations and send the added correlation coefficient to S3.

[0011] As a further improvement to this technical solution, step S1 is as follows:

[0012] S1.1 Establish an ultra-high-definition display system and set upload conditions for the resolution of image files and video files in the ultra-high-definition display system;

[0013] S1.2 Collect meeting files uploaded by meeting members in the ultra-high-definition display system, then verify the meeting files against the upload criteria, retain only the verified meeting files, and return the verified meeting files to the meeting members.

[0014] As a further improvement to this technical solution, step S2 is as follows:

[0015] S2.1 At the beginning of the meeting, the meeting documents will be projected onto the screen in real time through an ultra-high-definition display system, allowing meeting members to share and view the meeting documents through the ultra-high-definition display system;

[0016] S2.2 Divide the meeting documents into interactive areas based on content differences, so that the meeting document interface consists of multiple interactive areas;

[0017] S2.3 When meeting members need to upload interactive content, they can select an interactive area to upload the content. The interactive content will then be retained in the corresponding selected interactive area. The retained interactive content will be analyzed in the area minutes. First, the minutes of each interactive content will be analyzed, and then similar minutes will be merged. Based on the analysis results, the corresponding number of area minutes for each interactive area will be obtained.

[0018] As a further improvement to this technical solution, step S2.2 also includes the following steps:

[0019] S2.2.1 For image files, each image page is divided into separate interactive areas so that each image page has an interactive area.

[0020] S2.2.2 For video files, the playback content differences of the video files are analyzed, and the video files are segmented according to the analysis results, with each video segment serving as an interactive area.

[0021] As a further improvement to this technical solution, the steps in S3 are as follows;

[0022] S3.1 After the meeting begins, the speeches are recorded, and meeting minutes are generated based on the recorded speeches;

[0023] S3.2. Perform correlation coefficient analysis on the regional minutes of the interactive area based on the meeting minutes to obtain the correlation coefficient between the regional minutes and the meeting minutes, and filter and retain the regional minutes based on the correlation coefficient.

[0024] S3.2.1 Set a correlation threshold, then compare the correlation coefficients of the regional minutes with the correlation threshold, and only retain regional minutes with correlation coefficients greater than the correlation threshold;

[0025] S3.2.2 Set the number of regional minutes to be retained, sort the regional minutes according to the correlation coefficient, and then retain the corresponding number of sorted regional minutes according to the retention number.

[0026] As a further improvement to this technical solution, in step S3.2, either S3.2.1 or S3.2.2 can be selected as the retention analysis method.

[0027] Simultaneously, the association coefficients sent by S5 are received, the meeting members corresponding to the interaction content of the regional minutes are extracted, the additional association coefficients corresponding to each meeting member are obtained, and the highest additional association coefficient is selected and added to the association coefficient between the regional minutes and the meeting minutes.

[0028] As a further improvement to this technical solution, step S4 is as follows:

[0029] S4.1 Analyze the quick annotation operations of the interactive areas corresponding to the retained regional minutes set, obtain the quick annotation operation list based on the analysis results, and then display the quick annotation operation list to the meeting management terminal according to the correlation coefficient;

[0030] The higher the correlation coefficient, the higher the ranking of the quick annotation operation;

[0031] S4.2 Receive quick annotation operations from the meeting management terminal, modify and optimize the interactive area based on the feedback of quick annotation operations, and complete the meeting file update.

[0032] As a further improvement to this technical solution, step S5 is as follows:

[0033] S5.1 Record the historical quick annotation operations reported by the meeting management terminal during this meeting, and obtain the meeting members of the minutes corresponding to the historical quick annotation operations;

[0034] S5.2 Obtain the meeting duration and analyze the presentation duration of the completed interaction areas based on the meeting duration. Obtain the presentation duration of each interaction area, and then add additional correlation coefficients to the meeting members corresponding to the historical quick annotation operations based on the presentation duration of the interaction areas. Send the added correlation coefficients to S3.2 for subsequent correlation coefficient analysis.

[0035] The longer the speech, the greater the additional correlation coefficient, and there is an upper limit to the additional correlation coefficient.

[0036] As a further improvement to this technical solution, the step of adding the additional correlation coefficient in S5.2 is as follows:

[0037] ;

[0038] Where ΔC represents the additional association coefficient increase for the corresponding meeting member, T represents the presentation duration in the interactive area, and C max This is the preset upper limit for additional correlation coefficients, where k is the proportional coefficient.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. In the real-time projection and interactive annotation method of the meeting content in this ultra-high-definition display system, quick annotation operations are extracted based on the analysis of the filtered regional minutes and displayed to the meeting management terminal in order of correlation coefficient. The scope of the interactive area and annotation tools are dynamically modified and optimized based on the feedback from the management terminal. At the same time, historical quick annotation operations and corresponding member information are recorded to provide data support for subsequent annotation operation priority determination and correlation coefficient calculation. This dynamic optimization mechanism can continuously meet the actual discussion needs of the meeting, continuously improve the rationality of the interactive area and the practicality of the annotation function, enhance the system's adaptability to different types of meetings and different discussion scenarios, and bring a better interactive experience to meeting members.

[0041] 2. In the real-time projection and interactive annotation method of the ultra-high-definition display system, based on the differences in the content of the meeting documents, image files are divided into dedicated interactive areas by page and video files by content segments. This guides meeting members to conduct targeted interactions around specific areas. At the same time, by extracting the core information of the interactive content to generate minutes and merging similar content, valuable area minutes are selected by combining the correlation coefficient with the core meeting minutes. Additional correlation coefficients corresponding to the presentation duration are also incorporated to optimize the selection results. This series of operations not only reduces information redundancy but also accurately locks in the key content of the meeting, allowing members to quickly focus on key issues for discussion, greatly reducing interference from invalid information, and significantly improving the communication and collaboration efficiency of the meeting.

[0042] 3. In the real-time projection and interactive annotation method of the ultra-high-definition display system, by setting the upload resolution standard for meeting files at the source and conducting qualification verification of uploaded files, files that do not meet the ultra-high-definition display requirements are promptly returned to the meeting members. This measure fundamentally ensures the compatibility of the projected content with the ultra-high-definition display system, effectively avoiding problems such as blurry projection and image distortion caused by substandard file resolution. It provides a stable and high-quality visual foundation for real-time projection of subsequent meetings and smooth interaction between members, allowing all meeting members to clearly and synchronously obtain the meeting file content.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figure 1 - Figure 6 As shown, the purpose of this embodiment is to provide a method for real-time projection and interactive annotation of meeting content in an ultra-high-definition display system, including the following steps:

[0051] S1. Set the upload conditions for the ultra-high-definition display system and verify the eligibility of uploaded meeting files based on these conditions. By setting the upload conditions, select meeting files that meet the requirements of the ultra-high-definition display system to avoid affecting the projection effect due to substandard file resolution.

[0052] The steps for S1 are as follows:

[0053] S1.1 Establish an ultra-high-definition display system, and set upload conditions for the resolution of image and video files in the ultra-high-definition display system; ensure the display adaptability of the screen-projected content from the source, and lay the foundation for subsequent real-time screen projection and interaction.

[0054] S1.2 Collect meeting files uploaded by meeting members in the ultra-high-definition display system, then verify the meeting files against the upload criteria, retain only the verified meeting files, and return the verified meeting files to the meeting members.

[0055] S2. The meeting documents are projected in real time through an ultra-high-definition display system. Interactive areas are divided according to the differences in the content of the meeting documents. Meeting members upload interactive content through the corresponding interactive areas, and the interactive content in each area is analyzed in the form of area minutes. Based on real-time projection, the discussion focus is on the key points by dividing the interactive areas, and the interactive content is analyzed in the form of minutes, which is convenient for subsequent organization and association.

[0056] The steps for S2 are as follows:

[0057] S2.1 At the beginning of the meeting, the meeting documents are projected onto the screen in real time through the ultra-high-definition display system, allowing meeting members to share and view the meeting documents through the ultra-high-definition display system. The ultra-high-definition display system simultaneously enables file sharing permissions, and meeting members connect to the system through their respective terminal devices (such as computers, tablets, mobile phones, etc.) to receive the projection signal in real time, thereby enabling them to share and view the meeting documents and ensuring that all members can access the document content simultaneously.

[0058] Before the meeting begins, qualified meeting files (image files, video files, etc.) are imported into the projection module of the ultra-high-definition display system to complete the file format adaptation and loading process, ensuring that the files can be read normally by the system;

[0059] At the beginning of the meeting, the real-time projection function of the ultra-high-definition display system is activated to project the loaded meeting documents to the display terminal (such as an ultra-high-definition screen, projection device, etc.) through the system, so as to realize the real-time display of the meeting documents;

[0060] S2.2 Divide the meeting files into interactive areas based on content differences, so that the file interface of the meeting files consists of multiple interactive areas; perform type identification on the meeting files loaded in the ultra-high-definition display system to distinguish between image files and video files, in order to prepare for subsequent differentiated division of interactive areas;

[0061] S2.2 also includes the following steps:

[0062] S2.2.1 For image files, each image page is divided into separate interactive areas so that each image page has an interactive area. Taking each independent image page as a unit, the interactive area is divided into separate areas for each page. When dividing, the logical structure of the image content (such as different chapters, different chart areas, etc.) can be used to ensure that each image page corresponds to at least one interactive area, so that meeting members can focus on interaction within a specific page.

[0063] S2.2.2 For video files, the playback content is analyzed to identify differences. Based on the analysis results, the video file is segmented, with each segment serving as an interactive area. The system analyzes the playback content segment by segment to identify differences in content themes, scenes, or key information (such as discussions of different topics, different presentation clips, etc.). Based on the analysis results, the video file is divided into multiple consecutive segments, each of which serves as an independent interactive area, enabling members to precisely interact with different content segments of the video.

[0064] After S2.2.1 and S2.2.2 are completed, all interactive areas are integrated into the meeting file interface, so that the file interface clearly presents multiple independent and well-defined interactive areas, providing a structured operating space for subsequent members to upload interactive content.

[0065] S2.3 When meeting members need to upload interactive content, they select an interactive area to upload the content. The content is then stored in the selected area. A regional minutes analysis is performed on the stored content. First, each piece of interactive content is analyzed, and then similar minutes are merged. Based on the analysis results, the corresponding number of regional minutes for each interactive area is obtained. The steps are as follows:

[0066] Based on the discussion needs, meeting members select the corresponding interactive area (such as a specific area of ​​an image page or a segment of a video) in the meeting file interface of the ultra-high-definition display system, and upload the interactive content to be shared (such as text comments, annotations, questions, etc.) to that area. The system automatically associates the content with the selected area and saves it.

[0067] The process involves processing all interactive content within each interactive area, extracting the core information (such as keywords, viewpoints, and questions) of each piece of content, and transforming it into a structured single-piece summary. This ensures that the core meaning of each piece of interactive content is accurately extracted. Simultaneously, a similarity analysis is performed on all single-piece summaries within the same interactive area, merging summaries that express similar core meanings into a single comprehensive summary to avoid information redundancy. Ultimately, several merged regional summaries are generated for each interactive area, clearly presenting the core interactive information of that area.

[0068] S3. Record meeting speeches and generate meeting minutes. At the same time, perform correlation coefficient analysis on the regional minutes of the interactive area based on the corresponding meeting minutes, and filter and retain the regional minutes according to the correlation coefficient. Generate core minutes through meeting speeches, and then filter the regional minutes that are strongly related to the core content to ensure that the retained interactive information has practical value.

[0069] The steps for S3 are as follows;

[0070] S3.1 After the meeting begins, the meeting speeches are recorded. The ultra-high-definition display system activates the meeting speech recording function, and records the speaker's voice content in real time through audio acquisition devices (such as microphones). At the same time, it combines video acquisition (such as speaker's screen) to assist in recording, ensuring complete capture of the speech information, and generates meeting minutes based on the recorded meeting speeches.

[0071] The system converts the collected audio information into text, performs preliminary editing to remove redundant words and repetitive content, retains core sentences, and forms a structured transcript of the speech. Based on the edited transcript, the system extracts key information (such as meeting topics, discussion conclusions, to-do items, and important viewpoints), integrates it according to a preset minutes format (such as chronological order and topic classification), and generates a complete meeting minutes to ensure that the minutes accurately reflect the core content of the meeting speech.

[0072] S3.2. Perform correlation coefficient analysis on the regional minutes of the interactive area based on the meeting minutes to obtain the correlation coefficient between the regional minutes and the meeting minutes (calculated by comparing the core themes, keywords, and key viewpoints of both to reflect the closeness of their relationship). Based on the correlation coefficient, the regional minutes are then filtered and retained. The correlation coefficient analysis formula is as follows:

[0073] ;

[0074] Where C is the connection number (ranging from 0 to 1, with a larger value indicating a closer connection between the regional minutes and the meeting minutes), and K... a K is the set of keywords extracted from the regional minutes. b |K is a set of keywords extracted from meeting minutes. a ∩K b | represents the number of elements in the intersection of two keyword sets (the number of common keywords), |K a ∪K b | represents the number of elements in the union of two keyword sets (the total number of all unique keywords).

[0075] S3.2 When performing retention analysis, either S3.2.1 or S3.2.2 may be chosen as the method for retention analysis;

[0076] Simultaneously, the association coefficients sent by S5 are received, the meeting members corresponding to the interaction content of the regional minutes are extracted, the additional association coefficients corresponding to each meeting member are obtained, and the highest additional association coefficient is selected and added to the association coefficient between the regional minutes and the meeting minutes.

[0077] S3.2.1 Set the correlation threshold (if the overall deviation of the meeting documents is large, the correlation threshold can be gradually reduced as the meeting progresses. The correlation threshold range is 0-1, and it is dynamically adjusted according to the deviation of the meeting documents. For example, the initial value is 0.6, and it is gradually reduced to 0.5 as the meeting progresses). Then, the correlation coefficient of the regional minutes is compared with the correlation threshold, and only the regional minutes with the correlation coefficient greater than the correlation threshold are retained.

[0078] S3.2.2 Set the number of regional minutes to retain (when the number of minutes to retain is set to 5, only the regional minutes with the top five correlation coefficients will be retained). At the same time, sort the regional minutes according to the correlation coefficients, and then retain the corresponding number of sorted regional minutes according to the number of minutes to retain.

[0079] S4. Analyze the quick annotation operations of the retained regional minutes in conjunction with the corresponding interactive areas, and then display the quick annotation operations to the meeting management terminal based on the correlation coefficient. Optimize the interactive areas based on the quick annotation operations fed back by the meeting management terminal. Based on the filtered regional minutes, extract efficient annotation operations and optimize the interactive areas in conjunction with the management terminal feedback to improve the subsequent interactive experience.

[0080] The steps for S4 are as follows:

[0081] S4.1 Analyze the quick annotation operations of the interactive areas corresponding to the retained regional minutes set, obtain the quick annotation operation list based on the analysis results, and then display the quick annotation operation list to the meeting management terminal according to the correlation coefficient;

[0082] The higher the correlation coefficient, the higher the ranking of the quick annotation operation. The steps are as follows:

[0083] The selected and retained regional minutes are matched and associated with their corresponding interactive areas to clarify the interactive area corresponding to each regional minute, providing a correspondence for subsequent annotation operation analysis. Then, for the associated regional minutes and interactive areas, the core needs contained in the regional minutes (such as highlighting, question marking, supplementary explanations, etc.) are analyzed. Combined with the content characteristics of the interactive areas (such as the position of charts in images, key time points in videos), quick annotation operations (such as highlighting, annotation, arrow pointing, etc.) applicable to the area are generated, forming a preliminary quick annotation operation list. Finally, the quick annotation operation list is sorted according to the correlation coefficient between the regional minutes and the meeting minutes. The quick annotation operation corresponding to the regional minutes with the higher the correlation coefficient is, the higher the ranking of the regional minutes in the list. The sorted quick annotation operation list is pushed to the meeting management terminal for the administrator to view and select.

[0084] The management interface also allows users to select quick annotation operations and then make custom adjustments. The priority formula is as follows:

[0085] ;

[0086] Where P is the sorting priority of quick annotation operations, β is the weighting coefficient used to adjust the proportion of correlation coefficient and historical usage frequency in priority determination, which can be adjusted according to meeting needs, and F is the normalized value of the usage frequency of this type of quick annotation operation in historical meetings, the more frequent the use, the larger the value.

[0087] S4.2 Receive quick annotation operations from the meeting management terminal, modify and optimize the interactive area based on the feedback of quick annotation operations, and complete the meeting file update.

[0088] Specifically, the system precisely matches the quick annotation operations with the corresponding interactive areas, clarifying the specific interactive area targeted by each operation (such as a specific section of an image page or a segment of a video), providing a basis for subsequent modifications. Based on the matching results, the quick annotation operations are executed on the interactive areas: if the operation involves adjusting the area range, the boundaries of the interactive area are redefined; if the operation involves optimizing the annotation function, corresponding annotation tools (such as highlighting, annotation boxes, etc.) are added or adjusted for that area, making the interactive area more suitable for meeting discussion needs.

[0089] After the interactive area is modified and optimized, the system automatically updates the corresponding meeting files, synchronizing the adjusted interactive area and annotation functions to the projection interface of the ultra-high-definition display system and the terminal devices of all meeting members, ensuring that the file content viewed by all members is consistent and completing the real-time update of the meeting files.

[0090] S5 records historical quick-marking operations and obtains the meeting members corresponding to these operations. Simultaneously, it analyzes the presentation duration of completed interaction areas based on the meeting duration. Based on the presentation duration of the interaction areas, it adds an additional correlation coefficient to the meeting members corresponding to the historical quick-marking operations and sends this increased correlation coefficient to S3. By recording historical operations and analyzing presentation durations, it provides supplementary evidence for correlation coefficient calculation, enhancing the system's accuracy in judging the value of interactive content.

[0091] The steps for S5 are as follows:

[0092] S5.1 Record the historical quick annotation operations reported by the meeting management terminal during this meeting, and obtain the meeting members of the minutes corresponding to the historical quick annotation operations;

[0093] By associating historical quick annotation operations with the corresponding regional minutes, the meeting members who uploaded the regional minutes can be obtained, thus establishing a correspondence between quick annotation operations and meeting members.

[0094] S5.2 Obtain the meeting duration (based on the time difference between the meeting start time and the real-time time), and analyze the presentation duration of completed interaction areas and the presentation duration of completed discussion interaction areas based on the meeting duration. Combine the meeting records to determine the time span from the start to the end of the discussion for each interaction area, that is, obtain the presentation duration of each interaction area. Then, based on the presentation duration of the interaction area, add an additional correlation coefficient to the meeting members corresponding to the historical quick annotation operation, and send the added correlation coefficient to S3.2 for subsequent correlation coefficient analysis.

[0095] The longer the speech, the greater the increase in the additional correlation coefficient. There is also an upper limit to the additional correlation coefficient, as shown in the following formula:

[0096] ;

[0097] Where ΔC represents the additional association coefficient increase for the corresponding meeting member, T represents the presentation duration in the interactive area, and C max The upper limit of the preset additional correlation coefficient is used to limit the maximum increase of the additional correlation coefficient and avoid the excessive influence of a single region on the correlation coefficient. k is a proportional coefficient used to quantify the correspondence between the presentation duration and the increase of the additional correlation coefficient, which can be adjusted according to the actual situation such as the type of meeting and industry needs.

[0098] The front end focuses on interaction through area division, while the back end filters core information through correlation coefficients. At the same time, the interaction area is optimized through feedback from the management end. Ultimately, this achieves efficient screen projection, accurate interaction, and intelligent annotation of meeting content under the ultra-high-definition display system, thereby improving meeting collaboration efficiency.

[0099] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
