Description

Technical Field

[0001] The present application relates to the field of web page technology, and in particular to a document presentation method, apparatus, and computer equipment. Background Art

[0002] With the development of Internet technology, online meetings and online teaching have been widely used due to their convenience, cost savings, environmental protection and energy saving.

[0003] Taking online meetings or online teaching on a web page as an example, in related technologies, whether it is an online meeting or online teaching through a web page, usually, in order to ensure the effect of the online speech, the initiator can share the screen to demonstrate the manuscript being presented, so as to synchronize the presentation process to the receiving end.

[0004] However, in the related art, there is a problem that the presentation function is relatively single, resulting in poor synchronization effect to the receiving end. Summary of the Invention

[0005] Based on this, it is necessary to provide a document presentation method, device and computer equipment to address the above technical problems. When performing a document presentation, not only the document being presented can be shared, but also the editing content of the document by the initiator can be shared, which enriches the document presentation function to a certain extent and improves the effect of synchronizing the document to the receiving end.

[0056] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0057] The data storage method provided in the embodiment of the present application can be applied to a computer device.

Those skilled in the art can understand that Figure 1 The structure shown in the figure is only a block diagram of a part of the structure related to the solution of the present application, and does not constitute a limitation on the computer device to which the solution of the present application is applied. The specific computer device may include more or fewer components than shown in the figure, or combine certain components, or have a different component arrangement.

[0058] With the development of Internet technology, online meetings and online teaching have been widely used due to their convenience, cost savings, environmental protection and energy saving.

[0059] Web applications for online meetings or online lectures often require the display and simultaneous recording of presentations. Related technologies typically use a shared screen to display the presentation, or use a service to convert each page of the presentation into an image, which is then sent to the recipient via real-time communication technology.

[0060] However, both of the above presentation methods have certain issues. Screen sharing presents the following issues: ① Interactivity: Because presentations are typically static presentations without real-time interactive capabilities, audience interaction, such as accepting questions or feedback, may require additional tools or features. ② Privacy and sensitive information: Screen sharing can easily leak the initiator's private information. ③ Technical compatibility: Different screen sharing tools and platforms may have technical compatibility issues, resulting in some features not working properly. ④ Image quality and resolution: When screen sharing presentations, resolution and quality may be limited by network bandwidth and tool performance, which can result in poor image quality, especially for slides containing high-resolution images or complex animations. ⑤ Latency and frame rate: An unstable network connection can cause delays or low frame rates when sharing the screen, affecting the smoothness of the presentation and the viewing experience. Converting a presentation to an image and sending it to the recipient only allows for synchronized presentations and cannot be recorded as a video.

[0061] Based on this, the present application proposes a document presentation method, which obtains multiple document images corresponding to the document and the editing content of each document image by the initiator according to the document sent by the initiator, and then uses each document image and the editing content of each document image by the initiator as document presentation sharing information that needs to be synchronously shared to the receiving end, and synchronizes the document presentation sharing information to the receiving end to realize the presentation of the document. In this way, when performing a document presentation, not only the document being presented is shared, but also the editing content of the document by the initiator is synchronously shared to the receiving end, which enriches the document presentation function to a certain extent and improves the effect of synchronizing the document to the receiving end. In addition, such a document presentation method will only synchronize the document and the editing content of the document to the receiving end, and will not leak the privacy and sensitive information of the initiator.

[0062] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0063] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] In an exemplary embodiment, Figure 2 As shown, a document presentation method is provided, which is described by taking the method applied to a web server as an example, and includes the following steps 201 to 203. Among them:

[0065] S201 , in response to a document presentation request sent by an initiator, converting a document carried in the document presentation request into a plurality of document images.

[0066] The document presentation request may be a request sent by the initiator to the web server when the initiator has a need for a presentation. When sending the request to the web server, the initiator uploads the document to be presented to the web server, that is, the document presentation request sent by the initiator carries the document to be presented.

[0067] In an embodiment of the present application, after receiving the document presentation request sent by the initiator, the web server converts the document carried in the document presentation request into multiple document images.

[0068] For example, the web server may use tool software capable of processing documents to convert the document into multiple document images. For example, the Apache POI toolkit (Poor Obfuscation Implementation) may be used to convert the document.

[0069] S202: Obtain document presentation sharing information based on multiple document images.

[0070] In the embodiment of the present application, the document presentation sharing information includes the editing content of each document image by the initiator, wherein the editing content may include the content and marks annotated by the initiator on each page of the document.

[0071] In actual applications, the initiator can annotate relevant content and tags on the web page interface when presenting a document. The web page server can then obtain the content and tags annotated by the initiator, and then determine the document presentation sharing information based on each document image and the obtained content and tags.

[0072] For example, the web server obtains the content and marks annotated by the initiator on the web page interface, and then determines each document image and the corresponding annotation content and marks as the document presentation sharing information. In this way, the document presentation sharing information includes the editing content of each document image by the initiator (the content and marks annotated by the initiator) and each document image.

[0073] S203, synchronizing the document presentation sharing information to the receiving end.

[0074] For example, after acquiring the document presentation sharing information, the web server may synchronize the document presentation sharing information to the receiving end. For example, to ensure document synchronization and sharing between the initiating end and the receiving end, the document presentation sharing information may be sent to the receiving end via a full-duplex communication protocol.

[0075] It should be noted that in the embodiment of the present application, a web server operates the document of the initiator and forwards the document presentation sharing information to the receiving end. There is no technical compatibility issue between the screen sharing tool and the platform. That is, compared with the related technology of sharing screen presentations, this application does not have any technical compatibility issues and will not cause some functions to be unable to be used normally.

[0076] In the document presentation method provided in the embodiment of the present application, by responding to the document presentation request sent by the initiator, the document carried in the document presentation request is converted into multiple document images, and then based on the multiple document images, the document presentation sharing information is obtained. The document presentation sharing information includes the editing content of each document image by the initiator, and finally the document presentation sharing information is synchronized to the receiving end. In this method, based on the document sent by the initiator, multiple document images corresponding to the document and the editing content of each document image by the initiator are obtained, and then each document image and the editing content of each document image by the initiator are used as document presentation sharing information that needs to be synchronously shared to the receiving end, and the document presentation sharing information is synchronized to the receiving end to realize the presentation of the document. In this way, when the document presentation is being performed, not only the document being presented is shared, but also the editing content of the document by the initiator is synchronously shared to the receiving end, which enriches the document presentation function to a certain extent and improves the effect of synchronizing the document to the receiving end. In addition, this document presentation method will only synchronize the document and the editing content of the document to the receiving end, and will not leak the privacy and sensitive information of the initiator.

[0077] The document presentation sharing information includes the editing content of each document image by the initiator. When the initiator annotates or marks the document, it is achieved through a static canvas covered on the web page interface. Based on this, the following embodiment describes a method for obtaining document presentation sharing information.

[0078] In an exemplary embodiment, Figure 3 As shown, based on multiple document images, document presentation sharing information is obtained, including:

[0079] S301: Acquire at least one edited content drawn by an initiator on a static canvas of a webpage interface.

[0080] The canvas refers to a blank rectangular area on the screen where an application can draw or capture user input events.

[0081] In the embodiment of the present application, the web page interface where the initiator is located is covered by a static canvas, and the initiator can edit content on the static canvas of the web page interface.

[0082] For example, when the initiator draws and edits content on the static canvas of the web page interface, the server where the initiator is located can send the edited content drawn by the initiator to the web page server in real time, and the grid server can obtain the edited content drawn by the initiator on the static canvas of the web page interface.

[0083] S302: Determine the editing content corresponding to each manuscript picture according to the corresponding position of each editing content in the manuscript, and obtain the editing content of each manuscript picture by the initiator.

[0084] When the web server retrieves the edited content drawn by the initiator on the static canvas of the webpage interface, it can also retrieve the corresponding location of each edited content in the document. This allows the web server to determine the corresponding document image based on the corresponding location of each edited content in the document, that is, to determine the edited content corresponding to each document image, and thus obtain the edited content of each document image by the initiator.

[0085] S303: Determine each document image and its edited content as document presentation sharing information.

[0086] After obtaining the editing content of each document image by the initiator, the editing content of each document image and each document image can be used as document presentation sharing information.

[0087] In the document presentation method provided in an embodiment of the present application, at least one edited content drawn by an initiator on a static canvas of a web page interface is obtained, and then, based on the corresponding position of each edited content in the document, the edited content corresponding to each document image is determined, and the edited content of each document image by the initiator is obtained. Finally, each document image and the edited content of each document image are determined as document presentation sharing information. In this method, a static canvas is provided in the web page interface where the initiator is located. The initiator can draw the edited content on the static canvas of the web page interface. In this way, the edited content drawn by the initiator is sent to the web page server. The web page server can obtain the edited content of each document image by the initiator based on the corresponding position of each edited content in the document, and then use each document image and the edited content of each document image as document presentation sharing information.

[0088] When acquiring the edited content drawn on the static canvas of the webpage interface by the initiator, in order to ensure the real-time data acquisition and improve the efficiency of data transmission, the acquisition can be performed through a full-duplex communication protocol. Based on this, the following embodiment describes a method for acquiring the edited content.

[0089] In an exemplary embodiment, Figure 4 As shown, obtaining at least one edited content drawn by the initiator on the static canvas of the webpage interface includes:

[0090] S401: Acquire execution operations and / or marks of an initiator on a static canvas through a full-duplex communication protocol.

[0091] Among them, the full-duplex communication protocol makes data exchange between the client and the server simpler, allowing the server to actively push data to the client. The browser and the server only need to complete a handshake to directly create a persistent connection between the two and conduct two-way data transmission.

[0092] For example, the initiator's operations and / or markings on a document on a static canvas of a webpage interface can be transmitted in real time to the webpage server via a full-duplex communication protocol. Specifically, the webpage server obtains the initiator's operations and / or markings on the static canvas via the full-duplex communication protocol. Prior to communicating with the webpage server via the full-duplex communication protocol, the initiator can first transmit device information to the webpage server. This allows the initiator and the webpage server to communicate, and the initiator can then transmit the edited content of each document image to the webpage server.

[0093] It should be noted that in the embodiment of the present application, data is transmitted through a full-duplex communication protocol, which can improve the efficiency of data transmission and ensure the real-time performance of data transmission. Compared with the method of sharing screen presentations in related technologies, it will not be limited by network bandwidth, that is, it can reduce delays, ensure the smoothness of document presentations and viewing experience, and improve the image quality of documents.

[0094] S402: Determine the execution operation and / or mark as each editing content.

[0095] After the execution operation and / or mark of the initiator on the static canvas is acquired, the execution operation and / or mark may be used as various editing contents drawn by the initiator on the static canvas of the webpage interface.

[0096] In the document presentation method provided in an embodiment of the present application, the initiator's executed operations and / or marks on the static canvas are acquired via a full-duplex communication protocol, and the executed operations and / or marks are determined as various edited contents. In this method, because the initiator's document and the edited contents thereof need to be synchronized with the receiving end, to ensure real-time data transmission, the edited contents drawn by the initiator on the static canvas of the webpage interface can be acquired via a full-duplex communication protocol.

[0097] The document presentation sharing information includes the document image and the editing content of the document image by the initiator. When synchronizing the document image and the editing content of the document image by the initiator to the receiving end, different protocols can be selected for transmission. Based on this, the following embodiment describes the method of synchronizing the document presentation sharing information.

[0098] In an exemplary embodiment, synchronizing document presentation sharing information to a receiving end includes:

[0099] Each document image is sent to a receiving end via a hypertext transfer protocol; and the edited content of each document image is synchronized to the receiving end via a full-duplex communication protocol.

[0100] In actual applications, when presenting a document, the document is usually synchronized to the receiving end first. If the initiator annotates or marks the document, the edited content of the initiator will be synchronized to the receiving end. Therefore, for the document and the edited content, the document is synchronized first, and then the edited content is synchronized. Different protocols can be selected for the synchronization of the document and the edited content.

[0101] For example, each document image can be sent to the receiving end through the hypertext transfer protocol, and the receiving end can first display the document. If the initiating end displays the first document image, the receiving end will also display the first document image. When the initiating end edits the document image, the edited content of each document image can be synchronized to the receiving end through the full-duplex communication protocol.

[0102] In the manuscript presentation method provided in an embodiment of the present application, each manuscript image is sent to a receiving end via the Hypertext Transfer Protocol; and the edited content of each manuscript image is synchronized to the receiving end via a full-duplex communication protocol. In this method, the manuscript images and the edited content of the manuscript images in the manuscript presentation shared information are sent to the receiving end using different protocols, namely, each manuscript image is sent to the receiving end via the Hypertext Transfer Protocol, and the edited content of each manuscript image is synchronized to the receiving end via the full-duplex communication protocol.

[0103] When sending each document image to the receiving end, the web server can directly send it to the receiving end, or the web server can first send a notification to the receiving end, and the receiving end can obtain each document image after receiving the notification. Based on this, the following embodiment describes the method of sending document images.

[0104] In an exemplary embodiment, Figure 5 As shown, each document image is sent to the receiving end via the hypertext transfer protocol, including:

[0105] S501, sending a document reception notification to a receiving end via a full-duplex communication protocol.

[0106] After converting the document into a document image, the web server can store the document image in a database and send a document reception notification to the receiving end. The web server can send the notification to the receiving end via a full-duplex communication protocol, which can improve the efficiency of information transmission.

[0107] S502: According to the document acquisition request sent by the receiving end, each document image is sent to the receiving end through the hypertext transfer protocol.

[0108] After receiving the document reception notification sent by the web server, the receiving end can send a document acquisition request to the web server. When the web server receives the document acquisition request sent by the receiving end, it can send each document image to the receiving end through the hypertext transfer protocol.

[0109] In the manuscript presentation method provided in the embodiments of the present application, a manuscript reception notification is sent to a receiving terminal via a full-duplex communication protocol. Subsequently, in response to a manuscript retrieval request sent by the receiving terminal, each manuscript image is sent to the receiving terminal via the Hypertext Transfer Protocol. This method also provides another method for sending each manuscript image to the receiving terminal, namely, first sending a manuscript reception notification to the receiving terminal, and then sending each manuscript image to the receiving terminal upon receiving a manuscript retrieval request sent by the receiving terminal.

[0110] According to the multiple manuscript images corresponding to the manuscript, the corresponding video stream can also be obtained, and the video stream can also be synchronized to the receiving end as the manuscript presentation sharing information. Based on this, the following embodiment describes another way to obtain the manuscript presentation sharing information.

[0111] In an exemplary embodiment, Figure 6 As shown, based on multiple document images, document presentation sharing information is obtained, including:

[0112] S601: Receive a video stream sent by an initiator.

[0113] In the embodiment of the present application, the video stream is generated by the initiator drawing multiple manuscript images and the edited content of each manuscript image on a dynamic canvas of the web page interface. The canvas can be set to 60 frames per second to form a dynamic canvas.

[0114] The initiator can draw multiple document images and the edited content of each document image together in a dynamic canvas, and then convert the dynamic canvas into a video stream through the media capture and media streaming interface provided by the dynamic canvas.

[0115] For example, after generating a video stream based on multiple document images and the edited content of each document image, the initiator can send the video stream to a web server. The web server can receive the video stream sent by the initiator through real-time communication technology (webrtc, Web Real-Time Communication).

[0116] S602: Determine the video stream as document presentation sharing information.

[0117] After receiving the video stream sent by the initiator, the video stream can be determined as the manuscript presentation sharing information. In this way, the manuscript presentation sharing information includes each manuscript picture, the editing content of each manuscript picture by the initiator, and the video stream.

[0118] In the document presentation method provided in an embodiment of the present application, a video stream sent by an initiator is received. The video stream is generated by the initiator drawing multiple document images and the edited content of each document image on a dynamic canvas of a webpage interface, and the video stream is determined as document presentation sharing information. In this method, the initiator generates a video stream from the multiple document images and the edited content of each document image, and the webpage server can receive the video stream and also determine the video stream as document presentation sharing information.

[0119] The video stream is also included in the document presentation sharing information. When synchronizing the document presentation sharing information to the receiving end, the video stream also needs to be sent to the receiving end. Based on this, in an exemplary embodiment, synchronizing the document presentation sharing information to the receiving end includes:

[0120] The video stream is sent to the receiving end via a full-duplex communication protocol.

[0121] In an embodiment of the present application, the video stream can be sent to the receiving end through a full-duplex communication protocol. After receiving the video stream, the receiving end can use the video stream as an alternative solution for the presentation.

[0122] It should be noted that the video stream received by the receiving end can be sent by the web server, or the sending end can generate the video stream and send the video stream directly to the receiving end through webrtc.

[0123] In the document presentation method provided in the embodiments of the present application, a video stream is transmitted to a receiving end via a full-duplex communication protocol. This method provides an optional method for synchronizing the video stream to the receiving end. Due to the enhanced real-time nature of the full-duplex communication protocol, the video stream can be transmitted to the receiving end via the full-duplex communication protocol, thereby improving data transmission efficiency.

[0124] After receiving the video stream sent by the initiator, the web server can also record it as a demonstration video for subsequent viewing by the initiator or the receiving end. Based on this, in an exemplary embodiment, Figure 7 As shown, the method further includes:

[0125] S701, using video recording software to record the video stream to obtain a demonstration recording video of the manuscript.

[0126] After receiving the video stream from the initiator, the web server can use the video recording software to perform background routing on the video stream to obtain a presentation recording video of the document. Among them, the video stream can be recorded using a fast screen recording tool or a lightweight and highly scalable streaming media service software.

[0127] S702: Send the demonstration recorded video to the initiating end and / or the receiving end.

[0128] For example, after obtaining the demonstration recording video of the document, the web server can save the demonstration recording video in a database. When the initiator or the receiver needs to use the demonstration recording video subsequently, it can send a video acquisition request to the web server. After receiving the video acquisition request, the web server sends the demonstration recording video to the initiator and / or the receiver.

[0129] For example, after obtaining the recorded video of the presentation of the manuscript, the web server may also directly send it to the initiator and / or the receiver.

[0130] In addition, the demonstration recording video does not need to be sent to the initiator and the receiver. The demonstration recording video can be stored in the object storage. When the playback function is performed later, the demonstration recording video can be obtained from the object storage and played back.

[0131] In the document presentation method provided in an embodiment of the present application, a video stream is recorded using video recording software to obtain a document presentation video, which is then sent to an initiating end and / or a receiving end. In this method, upon receiving the video stream sent by the initiating end, the web server can use the video recording software to record the video stream into a presentation video. In this way, the presentation video can be sent to the initiating end and the receiving end for viewing.

[0132] In addition, in an exemplary embodiment, the present application also provides an optional example of a manuscript presentation method, such as Figure 8 As shown, the following steps may be included:

[0133] S801 , in response to a document presentation request sent by an initiator, convert the document carried in the document presentation request into multiple document images.

[0134] S802: Obtain execution operations and / or marks of the initiator on the static canvas through a full-duplex communication protocol.

[0135] S803: Determine the execution operation and / or mark as each editing content.

[0136] S804: Determine the editing content corresponding to each manuscript image according to the corresponding position of each editing content in the manuscript, and obtain the editing content of each manuscript image by the initiator.

[0137] S805: Determine each document image and its edited content as document presentation sharing information.

[0138] S806, sending each document image to a receiving end via a hypertext transfer protocol; and synchronizing the edited content of each document image to the receiving end via a full-duplex communication protocol.
