The following are detailed below.
In this embodiment, a live playback method according to an embodiment of the present invention will be described from the perspective of a live playback device, where the live playback device may be integrated in a terminal, that is, an anchor terminal, as shown in fig. 2a, the live playback method according to the embodiment includes the following steps:
step S201, receiving a live broadcast watching request sent by a first terminal.
In specific implementation, the anchor can enter a live broadcast room through a live broadcast application installed at the anchor to perform live broadcast, such as: talent exhibition live broadcast, teaching live broadcast, game live broadcast and the like, and correspondingly, the anchor broadcast can be talent exhibitors, teachers, game players and the like. When a viewer wants to watch the live broadcast of the anchor, the viewer can enter the live broadcast room through the first terminal and send a live broadcast watching request to the anchor terminal, and the anchor terminal receives the live broadcast watching request sent by the first terminal. In this embodiment, the first terminal refers to a terminal of a viewer watching a live broadcast.
Step S202, sending the live video stream to the first terminal.
Specifically, the anchor terminal may obtain a live video stream of the anchor, and send the live video stream of the anchor to a first terminal of a viewer entering the live broadcast room to watch live broadcast through the server.
Specifically, the method for the anchor side to acquire the live video stream of the anchor may include:
firstly, a video stream acquired by a local camera of a main broadcast end is acquired, and the acquired video stream is used as a live video stream of the main broadcast. The method comprises the steps of directly broadcasting by a camera, acquiring a real-time activity scene of a main broadcast by the camera, and taking the acquired real-time activity scene as a live broadcast video stream. Live scenes where this approach may be applicable are for example: teaching lecture live broadcasting scenes, talent skill showing live broadcasting scenes and the like, and the obtained live video stream can be a lecture video stream and a talent skill showing video stream.
And secondly, acquiring a video stream of a screen designated area from a local video memory of a main broadcast end, and taking the acquired video stream as a live video stream of the main broadcast. I.e. a screen-recording live broadcast, this way can be applied to live scenes such as: and playing a live game scene, wherein the obtained live video stream can be a game video stream in progress of a player.
And step S203, acquiring the interactive item initiated by the anchor.
In the live broadcasting process, the anchor can interact with the audience for some items, and the anchor end obtains the interactive items initiated by the anchor. For example, the anchor may call with the audience, ask questions to be answered by the audience, play some games with the audience, tell stories to the audience, and the like, and the anchor obtains the interactive items initiated by the anchor.
In a specific embodiment, the method for acquiring the interactive item initiated by the anchor may be as follows:
receiving an interaction request initiated by the anchor triggering an interaction control;
displaying an interactive item creation page in response to the interactive request;
and acquiring the interactive item which is input by the anchor in real time from the interactive item creating page, or acquiring the interactive item selected by the anchor from a material library from the interactive item creating page.
For example, as shown in fig. 2b, an interaction control may be provided for the anchor in the live application, and the anchor may trigger the interaction control (e.g., "i want to interact" in fig. 2 b) by means of finger click, voice input, or the like to initiate an interaction request, and the anchor displays an interaction item creation page in response to the interaction request. In this embodiment, the interactive item creation page may be displayed in a pop-up window, a list, a drop-down box, or the like, and in a specific embodiment, the interactive item creation page may be as shown in fig. 2c, and the interactive item creation page may provide two ways of creating an interactive item for the anchor, namely, first, real-time entry; and secondly, selecting from a material library.
In the real-time entry of the creation mode, the anchor can enter the interactive items at the corresponding positions of the pages according to the prompts of the entry frames, and the anchor end acquires the interactive items entered by the anchor. In the selection of the creation mode in the material library, the material library can be established in advance, the established material library can be stored locally at the anchor terminal or stored at a remote terminal, and the anchor terminal can open the material library according to the page prompt to select the required interactive items.
And step S204, merging the interactive items into the live video stream to obtain the live video stream merged with the interactive items.
The specific combination method may include the steps of:
generating a webpage layer, and displaying the interactive item in the webpage layer;
and merging the webpage layers in the live video stream to obtain the live video stream merged with the interactive items.
In this embodiment, a web page layer for displaying an interactive item may be generated by using a web page (web) technology, that is, a HyperText Markup Language (HTML) is used to construct page elements (e.g., characters, links, forms, etc.), a Cascading Style Sheet (CSS) is used to perform page layout (e.g., a typesetting Style, a font size, etc.), and a script Javascript is used to control page interaction (e.g., button response, mouse following, content input, etc.), so as to generate the web page layer.
When the Web technology is adopted to generate the Web page layer, the used language is the HTML language of World Wide Web Consortium (W3C) standard, and the generated Web page layer can run on a network and a standard browser, so that the interactive items displayed in the Web page layer can be displayed in a cross-platform manner. For example, the interactive items displayed on the web page layers can be displayed on a terminal configured with an ios system or an Android system, the terminal can directly display the web page layers on which the interactive items are displayed in a browser, or can call a page view (webview) in a live application program to display the web page layers on which the interactive items are displayed, and the problem of complex bottom layer adaptation and cross-platform development language does not need to be considered for the display of the web page layers.
In addition, in this embodiment, when the interactive item includes a formula, for example, the interactive item is a mathematical title that is mainly played, a formula renderer (for example, a LaTex renderer) may be used to render the formula as a picture embedded in the webpage layer, so as to optimize a display effect of the formula, for example: the color, the whole size and the like of the formula can be conveniently adjusted.
In a specific implementation, when the webpage layers are merged into a live video stream, the size of the webpage layers may be adjusted according to the window display size of the live video stream, for example, the size of the webpage layers may be adjusted to be the same as the window display size of the live video stream, and then the two are aligned to cover the display window of the live video stream with the webpage layers, so as to obtain the live video stream merged with the interactive item; for another example, the size of the webpage layer may be adjusted to be smaller than the window display size of the live video stream, and then the webpage layer is used to cover a part of the display window of the live video stream, so as to obtain the live video stream combined with the interactive item. In a specific embodiment, the display effect of the merged web page layer with the interactive item and the live video stream can be as shown in fig. 2 d.
And S205, sending the live video stream combined with the interactive item to the first terminal.
The first terminal can show the live video stream combined with the interactive item to a user of the first terminal, namely, a live audience is watched, so that the live watching can be interacted with the anchor program. For example, when the interactive item is an answer, the webpage layer incorporated in the live video stream is used to display the title given by the anchor, and the audience can answer the title on the webpage layer of the live video stream; for example, when the interactive item is a story of the anchor, the webpage layer merged on the live video stream can display the content of the story of the anchor, and the audience can see the content of the story spoken by the anchor on the webpage layer of the live video stream; for another example, when the interactive item is playing a game, the web page layer incorporated in the live video stream may display a game rule or a game guide, and the viewer may view the game rule or the game guide on the web page layer of the live video stream.
In addition, after the live video stream combined with the interactive item is obtained, the anchor terminal can also automatically delete or hide the webpage layer in the live video stream to end the interaction and continue the live broadcast. For example, after obtaining the live video stream merged with the interactive item, the anchor terminal may start a timer to time, and when the timed length reaches a preset time length, the anchor terminal may delete or hide the webpage layers merged in the live video stream to obtain the live video stream of the anchor, and continuously push the live video stream to the first terminal to end the interaction, so that the audience of the first terminal continuously watches the live broadcast performed by the anchor. In this embodiment, the preset duration may be an interaction duration reserved for the audience, and a value of the preset duration may be, for example, 30 seconds, 1 minute, or the like, and specifically may be a value according to an actual requirement of the interaction item. For example, timing may be performed after a live video stream incorporating the interactive item is obtained, and when the timing is as long as 30 seconds, the anchor terminal automatically deletes or hides the webpage layer. In a specific implementation, the timing may be performed in a countdown manner, and is not specifically limited herein.
Or after the live video stream combined with the interactive item is obtained, the anchor terminal may also delete or hide the webpage layer combined in the live video stream according to the operation of the anchor terminal to end the interaction and continue the live broadcast. For example, a stop control (e.g., "stop interaction" in fig. 2 b) may be provided for an anchor in a live application, after a live video stream merged with the interaction item is obtained, the anchor may trigger the stop control by means of finger click, voice input, and the like to initiate a stop instruction, the anchor receives the stop instruction initiated by the anchor, deletes or hides the web page layer in the live video stream, obtains a live video stream of the anchor, and continuously pushes the live video stream to the first terminal, so that the audience of the first terminal continuously watches the live broadcast performed by the anchor.
And step S206, recording the time corresponding relation between the interactive item and the live video stream.
Specifically, the initiation time of the interactive item relative to the live video stream may be recorded, and in addition, the duration time and the stop time of the interactive item relative to the live video stream may also be recorded.
In a specific embodiment, the recorded time correspondence may be as shown in table 1, for example:
interactive item Initiation time Duration of time Time of rest
Answering question 3 min 00 s 30 seconds 3 minutes and 30 seconds
Story telling 20 minutes and 01 seconds 1 minute 21 minutes and 01 seconds
Playing games 28 minutes and 05 seconds 15 seconds 28 minutes and 20 seconds
TABLE 1
And step S207, receiving a video playback request sent by the second terminal.
The second terminal is a terminal of a viewer who needs to watch and play back the live video, the viewer who needs to watch and play back the live video can send a video playback request to the anchor terminal through the second terminal, and the anchor terminal receives the video playback request sent by the second terminal.
And step S208, sending the live video stream to the second terminal.
And S209, simulating the anchor to initiate the interactive item at the corresponding moment according to the time corresponding relation to obtain the live video stream combined with the interactive item.
And step S210, sending the live video stream combined with the interactive item to the second terminal.
Specifically, the anchor terminal may simulate the anchor at a corresponding time according to the recorded time correspondence relationship to initiate a corresponding interactive item, display the initiated interactive item in a web page layer, and finally merge the web page layer on which the interactive item is displayed in a live video stream and send the web page layer to the second terminal.
For example, when the recorded time correspondence is shown in table 1, when the live video is played back, and when the playback reaches 3 minutes 00 seconds, the anchor terminal may simulate to initiate an interactive item of answering, display the title in a webpage layer, and combine the webpage layer with the displayed title in the live video stream to send to the second terminal, so that the audience at the second terminal can realize the interaction of answering when watching the playback; when the playback time reaches 20 minutes and 01 seconds, the anchor terminal simulates and initiates an interactive item of speaking a story, the content of the story is displayed in the webpage layer, and the webpage layer on which the story content is displayed is combined in a live video stream and sent to the second terminal, so that the audience of the second terminal can see the story spoken by the anchor terminal during the live broadcast when watching the playback time; when the playback time reaches 28 minutes and 05 seconds, the anchor terminal simulates and initiates the interactive item of playing the game, the game rule or the game instruction is displayed in the webpage layer, and the webpage layer on which the game rule or the game instruction is displayed is merged in the live video stream and is sent to the second terminal, so that the audience of the second terminal can see the game which participates in the anchor initiation when watching the playback time.
Further, the anchor terminal may delete the interactive item incorporated in the live video stream according to the recorded time correspondence, and continuously transmit the live video stream obtained after deletion to the second terminal, so that the audience at the second terminal can continue to watch the playback of the live video.
In this embodiment, when live broadcasting, when the anchor initiates an interactive item and watches live audience to interact, the anchor can record the time corresponding relation between the interactive item initiated by the anchor and the live video stream, and when playing back, the anchor can simulate the anchor to initiate the interactive item at a corresponding moment according to the recorded time corresponding relation, so that the audience watching the playback can also experience the interactive item, the audience watching the playback has the same interactive experience as the audience watching the live broadcast, and the interactive requirement in the playback process is solved.
In the live teaching scene, the anchor can be a teacher giving online lessons, a terminal used by the teacher for live broadcasting can be called a teacher end, the audience can include students learning through live broadcasting and students playing back learning through watching live video, a terminal used by the students learning through live broadcasting can be called a first student end, a terminal used by the students playing back learning through watching live video can be called a second student end, as shown in fig. 3a, the live broadcasting playback method in the scene includes:
step S301, receiving a live broadcast watching request sent by a first student terminal.
Step S302, sending the live video stream to a first student terminal.
For example, the teacher can get into the live broadcast room through the live broadcast application program that the teacher end installed, and after the teacher got into the live broadcast room, the teacher end can open the camera, acquires teacher's the video stream of giving lessons, passes through the server propelling movement with teacher's the video stream of giving lessons and needs watch live student's terminal, first student end promptly as live broadcast video stream.

The students at the first student end can answer questions combined in the live video stream, the first student end can feed back answer information of the students to the teacher end, the teacher end can feed back a review result to the first student end in real time according to the answer information, and further the teacher end can adjust teaching strategies according to the answer information of the students.
For example, after obtaining the answer information of the student, the teacher end may compare the answer information of the student with the correct answer of the question to obtain a review result, feed the review result back to the first student end in real time, and count the answer accuracy of the question made by the teacher according to the review result, if the answer accuracy is low, prompt the teacher to repeat or enhance the live broadcast of the course content related to the question, and the teacher adjusts the teaching content according to the prompt.
And S307, deleting a webpage layer in the live video stream, and continuously sending the live video stream to the first student side.
After the live broadcast video stream combined with the title is obtained, the teacher end can automatically delete or hide the webpage layer displaying the title in the live broadcast video stream so as to end the answering interaction and continue the live broadcast. For example, after obtaining the live video stream with the incorporated question, the teacher end may start a timer to time, and when the timed length reaches a preset time length, the teacher end may delete or hide the webpage layers incorporated in the live video stream to obtain the live video stream, and continuously push the live video stream to the first student end to end answering, so that the student continuously watches the live lecture broadcast performed by the teacher. In this embodiment, the preset duration may be the answer duration reserved for students, and the value of the preset duration may be, for example, 30 seconds, 1 minute, and may specifically be a value according to an actual demand. For example, as shown in fig. 3b, a countdown may be performed for 30 seconds after the live video stream with the title is obtained, and when the countdown reaches 0 second, the teacher end automatically deletes or hides the webpage layers.
Or after the live broadcast video stream with the merged title is obtained, the teacher end can delete or hide the webpage layer merged in the live broadcast video stream according to the operation of the teacher so as to finish answering and continue live broadcast. For example, a stop control may be provided for a teacher in a live application program, after a live video stream with a merged title is obtained, the teacher may trigger the stop control by means of finger click, voice input, and the like to initiate a stop instruction, the teacher receives the stop instruction initiated by the teacher, deletes or hides the webpage layer in the live video stream, obtains a live video stream, and pushes the live video stream to a first student terminal, so that the student continues to watch a live lecture broadcast performed by the teacher.
And step S308, recording the time corresponding relation between the titles and the live video stream.
Specifically, the start time of the title with respect to the live video stream may be recorded, and the duration and stop time of the title with respect to the live video stream may also be recorded. In a specific embodiment, the recorded time correspondence may be as shown in table 2 below:
topic of questions Initiation time Duration of time Time of rest
Choosing questions 10 min 00 sec 30 seconds 10 minutes and 30 seconds
Filling in the blank 20 minutes 00 seconds 30 seconds 20 minutes and 30 seconds
Question and answer 30 minutes 00 seconds 1 minute 31 min 00 s
TABLE 2
And step S309, receiving a video playback request sent by the second student.
The second student end is a terminal of a student needing to watch and play back the live video, the student needing to watch and play back the live video can send a video playback request to the teacher end through the second student end, and the teacher end receives the video playback request sent by the second student end. For example, a student misses the live time, a video playback request may be sent to the teacher end through the second student end to request to watch playback of the live video.
And step S310, sending the live video stream to a second student end.
And step S311, simulating the teacher to set questions according to the recorded time corresponding relation to obtain live video streams combined with the questions.
Specifically, the teacher end may simulate the teacher to output a corresponding title at a corresponding time according to the recorded time correspondence relationship, display the output title in a webpage layer, and finally merge the webpage layer on which the title is displayed in the live video stream.
For example, when the recorded time correspondence is shown in table 2, when the live video is played back, when the playback reaches 10 minutes and 00 seconds, the teacher end may simulate the teacher to generate a choice (the choice is the same as the choice generated by the teacher during live video), display the generated choice in the web page layer, and combine the web page layer on which the choice is displayed in the live video stream and send the live video stream to the second student end, so that the student watching the playback can answer the choice; when the playback time reaches 20 minutes and 00 seconds, the teacher end simulates the teacher to give a blank filling question (the blank filling question is the same as that given by the teacher in live broadcasting), the blank filling question is displayed in the webpage layer, and the webpage layer with the blank filling question is combined in the live broadcasting video stream and sent to the second student end, so that students watching the playback time can answer the blank filling question; when the playback time reaches 30 minutes and 00 seconds, the teacher end simulates the teacher to give out a question and answer (the question and answer are the same as those given out by the teacher in the live broadcast), the question and answer is displayed in the webpage layer, and the webpage layer with the question and answer displayed is combined in the live broadcast video stream and is sent to the second student end, so that students watching the playback time can answer the question and answer.
And step S312, sending the live video stream combined with the title to a second student end.
The student of the second student end can also solve the question combined in the played back live video stream, and the second student end can feed back the answer information to the teacher end, but the teacher end does not necessarily feed back the review result of the question to the second student end in time because the question is played back and the teacher is not necessarily on-line.
And step S313, deleting the webpage image layers in the live video stream according to the recorded time corresponding relation, and continuously sending the live video stream to the second student terminal.
For example, when the recorded time correspondence is shown in table 2, the anchor terminal may simulate the teacher to give a choice when the video is played back to 10 minutes and 00 seconds, and delete the choice displayed in the live video stream when the video is played back to 10 minutes and 30 seconds; when the video is played back to 20 minutes and 00 seconds, simulating a teacher to give a blank filling question, and deleting the blank filling question displayed in the live video stream at 20 minutes and 30 seconds; when the video is played back to 30 minutes and 00 seconds, the simulation teacher gives a question and answer, and deletes the question and answer displayed in the live video stream at 31 minutes and 30 seconds. In this way, students watching playback will have the same answering experience as students watching live.
In the embodiment, the teacher end synthesizes the questions in the live video stream in the form of the webpage layers, so that answer pages are provided for the student end, the answer pages are almost pushed to all students watching the live broadcast of the teacher at the same time by the server, therefore, the students watching the live broadcast can see the questions at the same time, and the questions can be isolated from the answering processes of different students due to the form display of the webpage layers, so that the independence of the answers is ensured, and the interaction of the mode of answering the teacher and the students is realized in the live broadcast process, and the interaction efficiency of the teacher and the students is improved.
Further, when broadcasting directly, through the time corresponding relation of the questions that the record mr made and live video stream to make when the playback, mr end can simulate mr to make the questions at corresponding moment according to the time corresponding relation of record, so that the student who watches the playback also can answer the questions that the teacher made when broadcasting directly, make the student who watches the playback have with watch the student of broadcasting directly the same answer experience of questions.
