[0043] The technical solution of the present application will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0044] Smart blackboards have gradually replaced traditional blackboards due to their convenience. When teachers use smart blackboards for teaching activities, they can not only call up teaching resources at any time to improve teaching efficiency, but also record and store the entire teaching process. If learners do not master the content in class, they can review and consolidate it by replaying the teaching courseware after class. When teachers conduct teaching activities, in order to increase learners' interest or explain a certain knowledge point, they often quote other people's opinions. This is fair use in normal teaching activities. However, once the teaching courseware is uploaded to the relevant Internet platform, it is very likely to infringe the original author's intellectual property rights and bring unnecessary trouble.

[0045] Embodiment 1: The digital memory interconnected blackboard and display screen integrated design system provided in this embodiment records the teaching process through the interconnected blackboard and various types of data acquisition devices to generate teaching content, analyzes the infringement risk of the teaching content to determine its permitted sharing scope, monitors the sharing process of the teaching content according to the sharing scope, and avoids infringement disputes in the process of disseminating the teaching content.

[0046] See also Figure 1-Figure 2 , the first aspect of the present application provides a digital memory interconnected blackboard and display screen integrated design system, applied to an intelligent blackboard, including: a data analysis module, and a data acquisition module connected thereto, the data acquisition module is connected to a plurality of data acquisition devices; the data acquisition module: used to collect teaching data in the teaching process through a plurality of data acquisition devices;

[0047] Data analysis module: used to pre-process a number of teaching data, generate and store teaching content; and, extract sensitive content from the teaching content, determine the sharing restriction level of the teaching content based on the sensitive content; determine the sharing scope of the teaching content based on the sharing restriction level.

[0048] The smart blackboard of this embodiment mainly includes a frame, a touch display panel, an interconnected blackboard and several data acquisition devices arranged on the frame, and the touch display panel and the interconnected blackboard can be linked. Several data acquisition devices mainly include a sound pickup device, a camera device, etc., which are used to record teaching activities. The specific components of the smart blackboard can refer to the existing technical solutions (such as the invention patent application with publication number CN113506476A), and the details thereof will not be repeated.

[0049] The teaching data in this embodiment includes audio, video and text. Audio data includes audio of the teacher's teaching and audio of interaction with learners, etc. Video data includes teaching actions and writing actions of the teacher during the teaching process, etc. Text mainly includes used documents, recognized handwritten documents of the teacher, etc. In some preferred embodiments, the video includes both images and audio, so the teaching data may only include video and text. After collecting the teaching data, pre-processing is required, mainly denoising, marking, etc., to improve data quality and facilitate subsequent analysis and processing.

[0050] In the present embodiment, during the teaching process, the teacher collects teaching-related content through a number of data collection devices, and integrates these contents to generate teaching content; the teaching content is actually a marked video file, and whether the teaching content has an infringement risk is determined by the marked sensitive content. If there is an infringement risk, the sharing scope is limited to ensure that the teaching content is disseminated within the scope of reasonable use for learners to learn.

[0051] This embodiment collects teaching data during the teaching process, including the following steps:

[0052] The intelligent blackboard is awakened by a wake-up instruction; data is collected in real time by a number of data collection devices; a set time period is extracted, and teaching data is extracted from the data collected in real time according to the set time period.

[0053] The above-mentioned wake-up instruction includes a touch instruction or a voice instruction, etc. The touch instruction can be a touch operation performed by the teacher on the touch display panel to wake up the smart blackboard, or a voice instruction can be used to wake up the smart blackboard. Of course, the smart blackboard can also be woken up by other wake-up methods, which are not listed here.

[0054] The teaching process of the teacher usually lasts for several minutes, so the set time period is determined according to the course type or the method set by the teacher. The teaching book is extracted from the real-time collected data every set time period. For example, video data is extracted every one minute and sent to the data analysis module for corresponding processing, which can avoid delaying sharing after the teaching activity is completed.

[0055] In some other preferred embodiments, the smart blackboard also includes a number of smart interactive terminals, which are used for learners to interact with teachers in real time in the classroom. For example, the teacher asks questions on the interconnected blackboard, and the learners give answers through the smart interactive terminals. The smart interactive terminals feed back the learners' answers to the touch display panel to achieve real-time interaction.

[0056] According to the provisions of "fair use" in the Copyright Law of the People's Republic of China, schools use published works for classroom teaching or scientific research, translation or a small amount of copying for teaching or scientific research personnel. After the teacher generates teaching content through the intelligent blackboard, even if the teacher allows it, if the teaching content involves citing other people's works and is uploaded to the relevant learning platform for profit, it will still constitute infringement of the original author. Therefore, before sharing the teaching content, this embodiment first determines whether there is a right dispute if the teaching content is used for profit. If there is no right dispute, the sharing scope is not set with the permission of the relevant copyright owner (party) such as the teacher, that is, anyone can obtain the teaching content through formal channels for learning. If there is a right dispute, it does not constitute an infringement for teaching or scientific research personnel to use according to the provisions of "fair use", then the sharing object of the teaching content can be determined as the teaching object or scientific research personnel, that is, the sharing scope of the teaching content is determined.

[0057] Example 2: The difference between this example and example 1 is that it provides a method for preprocessing a number of teaching data to generate teaching content; this example obtains teaching content by aligning and denoising a number of teaching data, and then marking the sensitive content therein. This method can effectively reduce the noise in the teaching content, improve the overall quality of the teaching content, and provide a data basis for determining the sharing scope in the future, avoiding the impact of excessive data volume on sharing efficiency. Please refer to Figure 3 , refer to the following steps for details:

[0058] The data analysis module generates teaching content, including:

[0059] Receive some teaching data; perform content alignment and content denoising on some teaching data to synthesize and obtain a video file; mark sensitive content in the video file to obtain teaching content.

[0060] After receiving a number of teaching data in a set period of time, the data analysis module performs content alignment and content denoising on the teaching data. Content alignment mainly refers to time alignment according to the acquisition time to ensure the synchronization of audio and image. Sometimes it may be difficult to solve the problem of audio and image asynchrony through time alignment. At this time, additional adjustments are required, such as manual adjustments or audio synchronization tool adjustments. Content denoising mainly removes noise in audio or images, as well as audio or images that are not related to teaching activities. After the above processing, the teaching data can achieve audio and video synchronization without noise, and then synthesize the teaching data into a video file, and then intelligently identify and mark the sensitive content in the video file to obtain the teaching content. It should be noted that the above-mentioned sensitive content is mainly quoted content, that is, the content of other works; of course, if it is considered that the teaching activities may involve confidential content, the sensitive content can also include these confidential contents.

[0061] In this embodiment, the specific steps of content alignment and content denoising are as follows:

[0062] First, the content of several teaching data is aligned according to time to obtain data group one; the content in data group one is identified, and the content noise is eliminated to obtain data group two; the audio and video in data group two are supplemented with materials, and the audio and video are synthesized into a video file.

[0063] For example, the teaching data is an audio stream and a video stream. First, align the audio stream and the video stream according to time, and use relevant tools to detect whether the audio and video are synchronized. If so, identify the content of the audio stream and the video stream. If there is noise in the audio stream, remove the noise. If the noise appears in a certain time range, the total length of the audio stream will be shortened; similarly, if there are invalid images or noise images in the video stream, remove the invalid images or noise images, which may also shorten the video stream. If part of the audio stream is removed, it may result in only images but no sound or incoherent sound during playback; if part of the video stream is removed, it may result in sound during playback, but a black screen. In response to the above problems, this embodiment solves them by supplementing materials, that is, removing the front and back audio connections of the audio to generate a complete audio stream (ensuring no distortion), or compressing the video stream to achieve coordination between audio and video. Of course, the missing parts can also be supplemented by existing materials to ensure the continuity of the audio and video streams. The above material supplement can be implemented based on the video repair model,

[0064] This embodiment performs content preprocessing on the collected teaching data, and performs intelligent recognition on the preprocessed video files, and generates teaching content after marking sensitive content. This embodiment ensures the overall quality of teaching content through content alignment and content denoising, and then marks sensitive content to form teaching content, which can provide a data basis for subsequent infringement risk analysis, without the need for centralized sensitive content recognition and marking, thereby improving its analysis efficiency.

[0065] Example 3: This example differs from Example 1 or Example 2 in that it provides a method for determining the sharing restriction level of teaching content based on sensitive content, judging whether there is an infringement risk based on the sensitive content in the teaching content, and setting the sharing scope of the teaching content based on the judgment result. Figure 4 , please refer to the following steps for details:

[0066] Determine the sharing restriction level of teaching content based on sensitive content, including:

[0067] Extract some sensitive contents from the teaching content and determine whether there is a risk of infringement. If yes, set the sharing restriction level of the teaching content to restricted level; otherwise, set the sharing restriction level of the teaching content to non-restricted level.

[0068] As can be seen from the above, the sensitive content of this embodiment is mainly quoted content or confidential content. Quoting does not necessarily mean infringement when it is not used reasonably. If the quoted content is common knowledge, there will be no ownership dispute. Therefore, this embodiment performs intelligent comparison on the sensitive content marked in the teaching content to determine whether the sensitive content has infringement risks. If there is an infringement risk, it is necessary to limit the sharing scope of the teaching content, that is, the sharing restriction level of the teaching content is set to restricted. If there is no infringement risk for all sensitive content, the sharing restriction level of the teaching content is set to unrestricted. The above-mentioned infringement risks can be automatically identified through deep learning algorithms, such as automatic monitoring methods based on RPA technology, ACRCloud audio detection solutions, various intellectual property automatic detection models, etc.

[0069] In this embodiment, when the sharing restriction level of the teaching content is non-restricted, the sharing scope of the teaching content is not restricted; when the sharing restriction level of the teaching content is restricted, the sharing scope is determined based on the comprehensive infringement risk of several sensitive contents. In other words, when the sharing restriction level of the teaching content is restricted, it is still necessary to determine the appropriate sharing scope based on the infringement risk of the teaching content. In other preferred embodiments, when the sharing restriction level of the teaching content is restricted, the corresponding sharing scope can be directly matched.

[0070] This embodiment also provides a method for calculating the comprehensive infringement risk of teaching content, including:

[0071] Calculate several infringement indicators for several sensitive contents in the teaching content separately; among them, the infringement indicators include quantity score, proportion score, originality score and market impact score; calculate the comprehensive infringement risk of the teaching content by combining several infringement indicators.

[0072] Specifically, we obtain the number of sensitive contents in the teaching content (Q), the duration ratio of sensitive contents (L), the potential impact of sensitive contents on the original work market (market substitutability) (C), and the originality of sensitive contents (R); we calculate the number of scores of sensitive contents in the teaching content (Q) respectively. s , originality score R s and Market Impact Rating C s ;in, Among them, T is the total duration of sensitive content, P is the total duration of teaching content, R is the originality of sensitive content, and R∈[0,1]; the comprehensive infringement risk Among them, i is the number of sensitive content, and β is the weight factor, which is adjusted according to actual conditions.

[0073] When the comprehensive infringement risk Risk<θ1, the teaching content is low risk; when θ1≤Risk<θ2, the teaching content is medium risk; when Risk≥θ2, the teaching content is high risk.

[0074] This embodiment mainly determines the sharing scope according to the comprehensive infringement risk by directly matching the sharing form. Specifically, when the teaching content is low-risk, it means that the infringement risk is relatively low even if the teaching content is not used reasonably, so it can be shared with some off-campus personnel, such as parents of students. When students encounter difficulties, parents can refer to the teaching content for answers, so the teaching content can be shared with students in the school and corresponding off-campus parents. When the teaching content is medium-risk, it is necessary to further restrict the sharing scope of the teaching content, such as only allowing students in the school to obtain the teaching content, so that even if there is an infringement risk, it can be quickly located and stopped in time, so the teaching content is shared with students in the school. When the teaching content is high-risk, it is necessary to limit it to the scope of reasonable use, so the teaching content is only shared with students in the corresponding class. In some other preferred embodiments, other ways to determine the sharing scope can also be given according to the comprehensive infringement risk of the teaching content.

[0075] During the sharing process of teaching content, it is necessary to verify whether the sharing object of the teaching content is within the matching sharing range. If so, the sharing is completed immediately; otherwise, the sharing of the teaching content is terminated.

[0076] The verification method can be to obtain other unique IDs by verifying the mobile phone number, name, etc.

[0077] This embodiment determines the corresponding risk level according to the comprehensive infringement risk of several sensitive contents in the teaching content, matches the teaching content in advance according to the risk level, and strictly restricts the sharing of the teaching content according to the sharing form; in this way, this embodiment can monitor the risks of the teaching content generated by the smart blackboard to ensure that it is within the scope of reasonable use and will not cause infringement disputes.

[0078] The above embodiments are only used to illustrate the technical method of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical method of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present application.
