It should be noted that the scene schematic diagram of the answer content pushing system shown in fig. 1 is merely an example, and the answer content pushing system and the scene described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

In the present embodiment, description will be made from the viewpoint of an answer content pusher device, which may be specifically integrated in a server.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for pushing answer content according to an embodiment of the present application. The answer content pushing method can comprise the following steps:

s101, acquiring live broadcast content, and sending the live broadcast content to a first client, so that the first client displays the live broadcast content in a live broadcast interface.

Wherein, live content can carry out nimble setting according to actual need, for example, this live content can be that the teacher gives lessons for the student on line through living, and this living can include at least a teacher this moment to and one or more student, and the teacher can join in living through the second customer end, and the student can join in living through first customer end. As another example, the live content may be a user participating in an online bonus race or the like.

In some embodiments, the live content may be acquired in real time or at preset time intervals, and the live content may include audio and video data input by the second client, or whether a trigger instruction is received may be detected, and when the trigger instruction is received, the live content may be acquired based on the trigger instruction. The audio-video data may only include audio data, or the audio-video data may only include video data, or the audio-video data may include both audio data and video data. For example, in the course of teaching by a teacher, audio and video data of the teacher can be collected by an audio collector such as a preset microphone, and the audio data can be uploaded to the server by the second client; for another example, in the course of teaching by a teacher, video data of the teacher can be acquired through a preset camera, and the video data can be uploaded to the server through the second client; for another example, during the course of the lecture, the teacher may capture an image of the lecture through a screenshot to obtain video data, and upload the video data to the server through the second client.

When the live content is that the teacher gives online lessons to students through live broadcasting, the first client can be a client used for online lessons on a terminal such as an intelligent television, a mobile phone or a computer used by the students, and the second client can be a client used for online lessons on a terminal such as an intelligent television, a mobile phone or a computer used by the teacher.

S102, when the knowledge point information related to the live broadcast content is acquired, determining target answer content corresponding to the knowledge point information.

The knowledge point information can be flexibly set according to actual needs, for example, when the teaching content is a physical class, the knowledge point information can include a mechanical energy conservation law, light scattering, a motion speed principle and the like, and keywords related to the knowledge point information can include the mechanical energy conservation law, mechanical energy, the conservation law, light scattering, the motion speed principle, motion, the principle and the like.

In some embodiments, the answer content pushing method may further include: acquiring audio data input by a second client; converting the audio data into character information; and carrying out semantic recognition on the character information to acquire knowledge point information related to the live broadcast content.

In order to improve the convenience and flexibility of knowledge point information acquisition, the knowledge point information related to the live content may be determined based on the audio data input by the second client. For example, in the course of a teacher giving a lesson, audio and video data of the teacher can be collected by an audio collector such as a preset microphone, and the audio data can be uploaded to the server by the second client. After the audio data is obtained, the audio data can be converted into text information, then word segmentation processing is carried out on the text information, semantic recognition and the like are carried out on words obtained through word segmentation processing, so that keywords related to knowledge point information are extracted from the text information, and the knowledge point information related to live broadcast content is determined based on the keywords.

In some embodiments, the answer content pushing method may further include: acquiring video data input by a second client, and performing character recognition on the video data to obtain character information; and carrying out semantic recognition on the character information to acquire knowledge point information related to the live broadcast content.

In order to improve the accuracy and flexibility of knowledge point information acquisition, knowledge point information related to live content may be determined based on video data input by the second client. For example, in the course of a teacher giving a lesson, video data of the teacher can be collected through a preset camera, and the video data can be uploaded to a server through a second client; for another example, during the course of the lecture, the teacher may capture an image of the lecture through a screenshot to obtain video data, and upload the video data to the server through the second client.

After the audio data is obtained, the text in the video data may be recognized, for example, the text on the image in the video data may be recognized through an Optical Character Recognition (OCR) algorithm, and the recognized text information is subjected to word segmentation and semantic Recognition (i.e., semantic analysis), so as to extract knowledge point information related to the live content from the text information, so as to analyze the knowledge point information currently being taught by the teacher in real time.

The target answer content corresponding to the knowledge point information may be determined as follows: and automatically and randomly selecting any one of the answer contents as the target answer content from the target answer contents corresponding to the knowledge point information, or selecting any one of the answer contents as the target answer content from the target answer contents corresponding to the knowledge point information based on the selection of a teacher, and the like.

In some embodiments, determining the target answer content corresponding to the knowledge point information may include: searching answer contents matched with the knowledge point information from a preset database to obtain candidate answer contents; sending the candidate answer content to a second client, and displaying the candidate answer content on the second client according to a preset priority; and determining the target answer content based on the selection instruction input by the displayed candidate answer content.

After the knowledge point information related to the live broadcast content is obtained, the answer content matched with the knowledge point information can be automatically searched from a preset database, so that the candidate answer content related to the knowledge point information can be obtained, the tedious step of manually configuring the answer content to the course chapter is omitted, and the efficiency and the convenience of screening the answer content related to the knowledge point information are improved.

The Database (Database), which can be regarded as an electronic file cabinet in short, a place for storing electronic files, can perform operations such as adding, querying, updating, deleting and the like on data in the files. A "database" is a collection of data that is stored together in a manner that can be shared by multiple users, has as little redundancy as possible, and is independent of the application.

In some embodiments, before searching for the answer content matching with the knowledge point information from the preset database, the answer content pushing method may further include: receiving an editing instruction input by a second client, and editing answer content and selecting knowledge point information according to the editing instruction; and generating answer content according to the edited answer content and the selection of the knowledge point information, and storing the answer content in a database.

In order to improve the convenience of pushing the answer content and the richness of the answer content, the answer content can be edited in advance and stored in a database. Specifically, an editing instruction input by the second client may be received, for example, an editing instruction generated by inputting voice or text and the like in an editing interface displayed by the second client may be input, then, the answer content may be edited according to the editing instruction, and the answer content corresponds to the knowledge point information selection, and the answer content editing may include inputting a question stem of the answer content, an option of the answer content, and an analysis of the answer content, and the like, for example, a keyword regarding the knowledge point of the mechanical energy conservation law may include the mechanical energy conservation law, the mechanical energy, the conservation law and the like. In this case, the answer content may be generated based on the edited answer content and selection of the knowledge point information (for example, a keyword of the knowledge point, which is regarded as a tag of the answer content), and the answer content may be stored in a database, which may store multiple pieces of answer content related to a plurality of pieces of knowledge point information. The types of the answer contents stored in the database can be flexibly set according to actual needs, for example, the types of the answer contents can include selection questions, short answer questions, blank filling questions, judgment questions or application questions, and the like.

It should be noted that when the keywords related to the knowledge point information extracted from the audio/video data relate to a plurality of knowledge points, the answer content related to any knowledge point information may be randomly selected as candidate answer content, or the answer content related to each knowledge point information may be all used as candidate answer content.

After the candidate answer content is obtained, the candidate answer content may be sent to the second client in real time or at regular time, for example, the candidate answer content may be sent to the second client after 30 minutes of live teaching, or every 10 minutes in the live teaching process. For another example, the candidate answer content may be associated with a keyword of the lecture content, and when the content is explained, the candidate answer content may be automatically transmitted to the second client. At this time, candidate answer content may be displayed at the second client according to a preset priority, where the candidate answer content may be displayed in a full screen, a popup window, or in a designated area in a live display interface. Therefore, the teacher does not need to configure the answering content in advance, candidate answering content of the relevant knowledge points is directly recommended to the teacher based on semantic recognition in live broadcasting, the candidate answering content can be conveniently used by the teacher after selection, and teaching experience of the teacher and comprehensiveness and flexibility of answering content pushing are greatly optimized.

The preset priority can be flexibly set according to actual needs, and specific contents are not limited here. For example, the candidate answer content may be randomly displayed at the second client, or for example, the candidate answer content may be displayed at the second client according to the frequency of the selected answer content, and the candidate answer content is displayed at a higher frequency and at a higher front; for another example, the candidate answer contents may be displayed at the second client in the order of the update time of the candidate answer contents, and the closer the update time is to the current time, the closer the update time is to the current time, the closer the display time is.

In some embodiments, displaying the candidate answer contents at the second client according to the preset priority may include: acquiring user identity information input by a second client; determining a preset priority according to the user identity information; and displaying the candidate answer content at the second client according to the preset priority.

In order to improve the flexibility of displaying candidate answer contents, answer contents which are frequently used by a user can be preferentially displayed based on the habit or preference of the user. Specifically, the user identity information input by the second client may be obtained, for example, a face image input by a user (e.g., a teacher) through the second client may be obtained, and the face image is subjected to face recognition to obtain the user identity information; for another example, fingerprint information input by the user through the second client may be acquired, and the user identity information of the user may be determined based on the fingerprint information; for another example, job number information input by the user through the second client may be acquired, and user identity information of the user may be determined based on the job number information; and so on.

Then, a preset priority can be determined according to the user identity information, and candidate answer content is displayed on the second client according to the preset priority. For example, for user a, the candidate answer contents may be randomly displayed at the second client, and for user B, the candidate answer contents may be displayed at the second client according to the frequency of the answer contents being selected.

In some embodiments, displaying the candidate answer contents at the second client according to the preset priority may include: acquiring the updating time of candidate answer content, and determining a preset priority level based on the updating time; and displaying the candidate answer content at the second client according to the preset priority.

In order to improve the reliability of the display of the candidate answer contents, the candidate answer contents may be displayed based on the update time of the candidate answer contents. The update time may be an editing time of the answer content or a storage time of the answer content stored in the database, and the editing time may be recorded when the answer content is edited or the storage time may be recorded when the answer content is stored in the database. For example, the update time of the candidate answer content may be obtained, the preset priority may be determined based on the update time, and the priority of the answer content display may be set to be higher as the update time is closer to the current time, whereas the priority of the answer content display may be lower as the update time is farther from the current time. At this time, the candidate answer content and the corresponding priority thereof may be sent to the second client, and the candidate answer content is displayed at the second client according to the preset priority. For example, a control instruction carrying the candidate answer content and the priority corresponding to the candidate answer content may be sent to the second client, and the second client is controlled to display the candidate answer content in a list form or other forms according to the preset priority based on the control instruction.

After the candidate answer content is displayed by the second client, the candidate answer content may be selected by a user (e.g., a teacher), for example, the user may input a click operation, voice information, or a gesture in the display list of the candidate answer content to generate a selection instruction, and determine a target answer content to be selected based on the selection instruction. The target answer content may be one question, of course, the target answer content may also be multiple questions, and the candidate answer content may be a selection question, a short answer question, a blank filling question, a judgment question, or the like. The method and the system realize that corresponding candidate answer contents can be judged and recommended according to semantic recognition when corresponding knowledge points are spoken in the live teaching process of teachers, so that teachers can select target answer contents from the candidate answer contents and click the target answer contents to issue the target answer contents.

In some embodiments, after determining the target answer content corresponding to the knowledge point information, the answer content pushing method may further include: acquiring the pushing time of the target answer content; and generating a playback file according to the pushing time and the target answer content, and storing the playback file.

In order to facilitate students to review the knowledge points efficiently, playback files related to the target answer content can be generated, so that the playback files can be played in the following process. For example, the pushing time of the target answer content may be obtained, where the pushing time may be the time from when the teacher gives lessons to when the target answer content corresponding to the current knowledge point is pushed, and the pushing time of the target answer content may be recorded when the target answer content is pushed. At this time, a playback file may be generated according to the push time and the knowledge point and analysis of the target answer content, and the playback file may be stored. Therefore, in the process of watching the playback file, the students can read the content in the playback file without repeatedly recognizing the voice in the video, and can display the answering content related to the corresponding knowledge point information in the process of watching the playback file.

In some embodiments, the playback file is generated according to the push time and the target answer content, and after the playback file is stored, the answer content push method may further include: when a playback instruction sent by the first client is received, feeding back a pre-stored playback file to the first client based on the playback instruction so that the first client can play the playback file.

In order to improve the convenience of reviewing the knowledge points, the students can watch the playback files according to their needs, for example, whether a playback instruction sent by the first client used by the students is received or not can be detected, and the playback instruction can be generated based on triggering a playback button or inputting playback voice information and the like. When a playback instruction sent by the first client is received, the pre-stored playback file can be fed back to the first client based on the playback instruction, so that the first client can play the playback file. When the live session is that a teacher gives online lessons to students through live broadcasting, the first client can be a client used for surfing the lesson on terminals such as an intelligent television, a mobile phone or a computer used by the students.

S103, pushing the target answer content to the first client side so that the target answer content is displayed in a floating mode in a live interface of the first client side.

After the target answer content is determined, the target answer content can be pushed to a first client side in a live broadcast session, the target answer content is displayed in a suspension mode on the first client side, the live broadcast content cannot be influenced by the suspension display answer content, and the target answer content can be displayed in a popup window or in a designated area in a live broadcast display interface. Wherein, the answering content display interface of the first client can be realized by adopting web technology, for example, the web is directly introduced to enable the first client to display the embedded answering content by opening a webpage view webview, so that a set of codes can be operated at multiple ends (for example, multiple first clients used by multiple students), the development cost is greatly reduced,

it should be noted that the distribution time of the target answer content may be set in advance, and in the course of live teaching, when the distribution time is up, the target answer content is automatically distributed, so that the student can receive the target answer content to answer.

In some embodiments, after the targeted answer content is pushed to the first client, the answer content pushing method further includes: displaying target answer content on a popup window of a first client, and displaying a display window displayed by the popup window in a live broadcast interface of the first client in a suspending manner; receiving answer information fed back by a first client; when the answer is judged to be correct based on the answer information, closing the display window displayed by the popup window; and when the answer is judged to be wrong based on the answer information, sending other answer contents in the candidate answer contents to the first client so as to be answered by the first client, and inputting the target answer contents with wrong answers into the historical answer recording information corresponding to the first client.

Displaying the targeted answer content at the first client may include: and displaying the target answer content in a popup window of the first client. In order to improve the flexibility of displaying the target answer content at the first client, the target answer content may be displayed in a pop-up window of the first client, and a display window displayed by the pop-up window is displayed in a live interface of the first client in a floating manner. At this time, the display window of the target answer content displayed by the first client popup window can be freely dragged, enlarged, reduced or closed, so that the student can give consideration to the lecture content of the teacher live broadcast or the discussion area content in the answer process, and the answer process is not disconnected from the live broadcast content.

Compared with the prior art, the student is unhook with the live content of giving lessons when answering: the existing answer form is that students directly display in full screen, answer in full screen, which means that students need to leave the live broadcast room temporarily, i.e. leave the live broadcast content for answering temporarily, and can get off-hook with the current live broadcast content temporarily. Scenes such as students wanting to answer questions while watching teaching contents will cause great interference to the user experience. According to the embodiment of the application, the target answer content is displayed through the popup window, answer is carried out in the display window displayed in the detection mode, the full screen is not needed, and the display screen is not unhooked with the live content, so that the flexibility of target answer content display and the convenience of student answer are improved.

It should be noted that, the popup window display may be provided with a transparency, and the transparency may be flexibly set according to actual needs, for example, the transparency of the popup window display may be set according to the usage habits of students, or the transparency of the popup window display may be changed along with the number of times of answering questions and answering mistakes, for example, as the number of times of answering mistakes is increased, the transparency of the popup window display may be decreased, the influence on watching live broadcast content is larger, and conversely, as the number of times of answering mistakes is decreased, the transparency of the popup window display is higher, and the influence on watching live broadcast content is smaller.

The answer information may be an answer result submitted by the student, the historical answer recording information may be related information of historical answers of the student, and the historical answer recording information may include wrong answer content, right answer content, mastered knowledge points, and unsophisticated knowledge points.

The student can conveniently master the knowledge point mastering condition of the student and can clearly master the knowledge point mastering condition of the student, the knowledge point mastered by the student can be continuously and deeply exercised subsequently, a teacher can conveniently know the knowledge point mastering condition of the student, historical answer record information of the student can be counted, and the knowledge point mastering condition of the student can be fed back through the historical answer record information.

Specifically, after the first client submits the answer result to generate the answer information, the answer information fed back by the first client may be received, then the answer information is compared with the pre-stored standard answer, if the answer information is matched with the standard answer, the answer is determined to be correct, and if the answer information is not matched with the standard answer, the answer is determined to be incorrect.

When the answer is judged to be correct based on the answer information, the display window displayed by the popup window can be automatically closed, the prompt information related to the answer can be displayed, and the prompt information can be automatically or manually closed. When the answer is judged to be wrong based on the answer information, the target answer content of the answer error can be input into the historical answer record information corresponding to the first client (for example, in an answer book capable of inputting the historical answer record information corresponding to the first client, students can check and see the historical answer record information after lessons), prompt information related to the answer error can be displayed, and the prompt information can be automatically or manually closed, and other answer contents except the target answer content in candidate answer contents can be sent to the first client, namely other answer contents with the same knowledge point as the target answer content are pushed for the first client to continuously answer, so that the students can continuously practice optimization, the mastering capacity of the knowledge point is improved, a display window displayed by a popup window can be automatically closed after the students answer contents are answered, and certainly, the students can also independently and manually close the popup window, The display window displayed by the pop-up window is enlarged, reduced or moved, so that the answering process of the students is more free and personalized. The other answer contents may be randomly selected from the answer contents other than the target answer content in the candidate answer contents, or the answer contents ranked close to the target answer content may be pushed as the other answer contents. The method has the advantages that the questions related to the teaching contents of the students can be efficiently pushed in real time in the teaching live broadcast process, so that the students can answer the questions while watching the teaching live broadcast, the knowledge points are consolidated, and the learning efficiency is improved.

It should be noted that when the students judge the answer error based on the answer information, the knowledge points of the students can be obtained based on the historical answer record information of the students, and different answer contents are respectively pushed to the first client corresponding to each wrong student according to different knowledge points of different students, so that different students can perform intensive training according to the actual conditions of the students.

In some embodiments, receiving the answer information fed back by the first client may include: receiving answer information of the first client based on voice feedback; or receiving answer information fed back by the first client based on the click operation; or receiving answer information fed back by the first client based on the text box input.

In order to improve flexibility, efficiency and convenience of answering, the answering can be performed through voice, click operation or text box input and the like, for example, for answering content displayed in a display interface, students can input own answers through voice to generate answering information based on semantic recognition of the input voice, and at the moment, the answering information of a first client based on voice feedback can be received, so that manual operation can be replaced through voice answering. For another example, for the answer content displayed in the display interface, the student may input the option selected by the student through a click operation to generate answer information, and at this time, the answer information fed back by the first client based on the click operation may be received. For another example, for a text box in which the answer content displayed in the display interface corresponds to the answer, the student may input the answer of the student through the text to generate the answer information, and at this time, the answer information fed back by the first client based on the input of the text box may be received.

The method described in the above embodiments is further illustrated in detail by way of example.

In this embodiment, the answer content push device is integrated in a server, which is taken as an example of a server cluster, and a teacher gives lessons on students live online, where the server cluster may include servers such as an access layer server, an audio/video server, a question bank server, a voice-to-text server, a playback file server, a WebSocket server (also referred to as a full-duplex communication protocol server), a PushAgent server (also referred to as a push proxy server), and a data storage server, and a connection relationship between the servers in the server cluster may be as shown in fig. 3, where the server cluster may be communicatively connected to a student terminal (i.e., a client terminal used by a student, which may be an APP terminal, a Web terminal, or a PC client terminal used by the student) through the access layer server or the WebSocket server, and the teacher terminal (i.e., a client terminal used by the teacher) through the access layer server or the WebSocket server The teacher end can be used as a main broadcasting client end, and the student end can comprise one or more than one. The server cluster can also be in communication connection with the access layer server through a question editing end (i.e. a client end for editing answer content, which can be an answer content configuration system).

The access layer server may serve as a gateway service, and is configured to receive an http request from a student end, a teacher end, or a title editing end, and forward the http request to a processing service corresponding to a Uniform Resource Locator (URL). The audio and video server can be used for receiving live audio and video data sent by the teacher end through the access layer server. The question bank server can be used for processing the request related to the answering content (also called practice questions). The voice-to-text server can be used for receiving audio data generated by live teaching of a teacher end and converting the audio data into text information. The push agent server can be used for receiving a push (push) request issued by the question bank server and forwarding the push request to a specified push channel, such as a WebSocket channel. The WebSocket server can be used for establishing WebSocket (namely, a full-duplex communication protocol based on TCP) link with a student end and a teacher end and pushing a message sent by a PushAgent server in real time. The playback file server can be used for generating a playback file for recording relevant information of the exercise answer content in the process of the teacher giving a lesson, and the student end can analyze the playback file when watching the playback and display the exercise answer content at the corresponding playing position of the video. A data storage server (which may be a database) may be used to store data.

Before a teacher gives a live online lecture to a student, the teacher may first perform configuration of answer content (i.e., a question) in advance, and a flow diagram of the configuration of the answer content provided in the embodiment of the present application may be as shown in fig. 4, where the flow may include:

and S10, the title editing end receives an editing instruction input by a teacher, and edits the title and selects the knowledge point corresponding to the title based on the editing instruction.

S11, after the title editing is completed and the corresponding knowledge point is selected, the title and its related information (which may be referred to as title information for short) can be uploaded to the title library server.

And S12, storing the question information of the question bank server into a database on the data storage server. The topic information can include the topic stem, options, correct answers, parsing, knowledge points involved, edit time, etc. of the topic.

And S13, after the title information is successfully stored, the data storage server can return a successful storage message to the title library server.

S14, the question bank server returns a storage success message to the question editing end.

In the process of online live-broadcast lectures of students by teachers, questions related to knowledge point information (also referred to as knowledge points for short) of the lecture contents of the teachers can be recommended and displayed at the teachers. A schematic flow diagram of topic recommendation related to knowledge point information provided in an embodiment of the present application may be shown in fig. 5, where the flow may include:

and S20, adding the live broadcast session into the teacher end, and recording live broadcast audio (namely audio data, which can also be referred to as audio for short) generated in the live broadcast teaching process of the teacher. For example, audio data of a teacher may be collected by a microphone or other audio collector.

And S21, uploading the audio data to an audio and video server by the teacher end through the access layer server, uploading the audio data to a question bank server by the audio and video server (for example, the audio and video server bypasses the audio data to the question bank server), and uploading the audio data to a voice-to-text server by the question bank server.

S22, the voice-to-text server converts the audio data into text (i.e. text information).

And S23, the voice-to-text server returns the text to the question bank server.

S24, the question bank server searches the question related to the knowledge point information related to the character (i.e. candidate question) from the question database stored in advance. For example, the question bank server may parse the text, perform semantic recognition on the text, obtain a keyword related to the knowledge point information, and search a question (i.e., a candidate question) matching the keyword from a database of pre-stored questions.

S25, the question bank server pushes the question related to the knowledge point information related to the characters to the PushAgent server, and the PushAgent server pushes the question to the WebSocket server.

S26, the WebSocket server pushes the titles related to the knowledge point information related to the characters to the teacher end in a title list mode, and therefore the titles are pushed to the teacher end through the push service.

S27, after receiving the title, the teacher end can display the currently pushed title list in a popup window.

For example, as shown in fig. 6, a teacher end may preset a position in a live teaching interface to popup a question list, and when there are many questions, may expand the first few questions whose display priorities are earlier, and hide and display other questions, and the determination method of the question display priorities is similar to that described above, and is not described here again. When the teacher needs to view all the topics, the expand button (e.g., "more > >) can be clicked to show all the pushed topics. It should be noted that, in order to facilitate communication between the teacher and the student during the course of the lecture, in addition to displaying the lecture content (such as the PPT courseware), a forum may be provided in the live lecture interface to display the discussion content of the teacher and the student. The question list can be manually closed according to the requirements of teachers, or automatically closed after the questions are pushed to students, or automatically closed after the display time reaches the preset time, and the like, wherein the preset time can be flexibly set according to actual needs.

After the teacher end displays the question list, the teacher can select any question from the question list and push the selected question to the student end, namely, the question pushing of exercise is initiated, so that the student can answer the question, and the knowledge points learned in the current class can be further consolidated. A schematic flow diagram of topic pushing for initiating exercise provided in an embodiment of the present application may be shown in fig. 7, where the flow may include:

s30, the teacher end receives the selection instruction input by the teacher and selects the item to be pushed (namely the target item) from the displayed item list based on the selection instruction.

S31, the teacher sends the item to be pushed (i.e. the target item) to the item library server.

S32, the question library server pushes the question to the WebSocket server through the PushAgent server.

S33, the WebSocket server pushes the title to the student terminal.

And S34, displaying the title through a popup window at the student end.

For example, as shown in FIG. 8, the student side may display lecture content within the display interface of the current live session, display images of the teacher in the authorized teacher video display area, and display discussion content of the teacher and the student in the discussion area. After receiving the title pushed by the WebSocket server, the student end can display the title through a popup window, and at the moment, the student can freely drag, enlarge, reduce or close the display window for displaying the title through the popup window, so that the student can give consideration to the lecture content of the teacher or the content of the discussion area in the process of answering the title.

S35, after receiving the title pushed by the teacher, the title library server may record the time for pushing the title and the title information, and send the time for pushing the title and the title information to the playback file server.

It should be noted that the execution sequence between step S32 and step S35 is not limited, and for example, step S32 and step S35 may be executed simultaneously, or step S32 may be executed first and then step S35 may be executed, or step S35 may be executed first and then step S32 may be executed.

S36, the playback file server writes the push time of the title, the title information, and the like in the playback file.

The follow-up student end can acquire and play the playback file, so that students can display the topics related to the corresponding knowledge point information in the process of watching the playback file, and the knowledge points can be reviewed efficiently.

After the student end displays the subject to be trained, the student can answer the displayed subject, the flow diagram of student answering provided by the embodiment of the application can be shown in fig. 9, and the flow can include:

and S40, the student end receives the answer instruction input by the student and answers the question (namely answers the question) based on the answer instruction.

And S41, submitting answers corresponding to the questions to the question bank server based on the answers of the students.

And S42, the question bank server determines the answer result.

The answer result can comprise correct answer, wrong answer and the like, after the student submits the answer at the student end, the question bank server can judge whether the answer is correct, and if the answer is correct, the student end closes the answer window. If the answer is correct, the question bank server returns the similar question corresponding to the knowledge point until the student answers the question.

And S43, the question bank server returns the answer result to the student end.

For example, as shown in fig. 10, when a student answers a wrong question, the question bank server may return an answer result of the wrong question to the student, and at this time, the display interface of the student may display the prompt information related to the wrong question. For another example, as shown in fig. 11, when the student answers correctly, the question bank server may return an answer result of correct answer to the student end, and at this time, the display interface of the student end may display the related prompt information of correct answer.

And S44, the question bank server records the answer condition of the student.

The answer condition may include information such as a wrong answer question, a right answer question, a mastered knowledge point, and an unsophisticated knowledge point, for example, the question bank server may record the wrong answer question into a wrong answer book in the database, as shown in fig. 12, and the student may check the wrong answer question through the wrong answer book. For example, as shown in fig. 13, the student can click on the wrong knowledge point in a course in the wrong exercise book, and display the wrong knowledge point at the student end for the student to practice.

The question bank server can also count the mastering conditions of the knowledge points of the students. For example, as shown in fig. 14, it is possible to count the knowledge points mastered by the student and the knowledge points not mastered by the student, and the student can click a certain knowledge point to view the related subject, so that the student can continue to practice optimization and improve the mastery ability of the knowledge points.

The audio data of the teacher in the live-broadcast lesson giving process can be intelligently identified and converted into character information, the knowledge point currently taught by the teacher is analyzed in real time, the question related to the knowledge point information is intelligently selected from the database, and the question related to the knowledge point information is pushed to the teacher end. Then, the questions selected by the teacher and needing to be exercised are pushed to the student end, and the student end pops up windows to display the questions for the students to answer. According to the scheme, the questions can be automatically matched and pushed based on the audio data, and the flexibility, comprehensiveness and convenience of pushing the questions are improved.
