That is to say, in the process of the segmentation module 102 segmenting the video, the video frame images of every two video segments that may be played continuously are the same, so that the seamless connection of video playing is facilitated.
In this embodiment, the editing module 103 further edits the file name of each video clip to be the same name, so that the playing module 104 uses the same video stream name to stream the video clip.
It can be understood that, in other embodiments, a user may record a video segment for each topic, and during the recording process, it is kept that a first frame image of an analytic video segment corresponding to each topic is the same as a last frame image of a video segment containing the topic, a last frame image of a video segment corresponding to each topic is the same as a first frame image of a video segment corresponding to a next topic, and a last frame image of an analytic video segment corresponding to each topic is the same as a first frame image of a video segment corresponding to a next topic. The storage module 101 stores a plurality of video segments recorded by users for different titles to the memory 20.
The playing module 104 is configured to transmit a video clip to the user end 2 for playing.
In this embodiment, at the beginning of the online classroom, the video segment is the first sequenced video segment. The playing module 104 decodes the video data encapsulated in the video segment, and transmits a code stream generated by decoding to the user end 2 for playing. The user end 2 may play the video clip through a web browser or an application client.
In this embodiment, the playing module 104 transmits the video segment to the user end 2 for playing, which includes performing reading and writing operations on a plurality of video frames in the video segment. Wherein the reading operation is reading a video frame from the video clip, and the writing operation is streaming the read video frame.
In this embodiment, in order to counter the delay caused by network jitter and other factors, during the playing of the video segment, the reading operation of the playing module 104 on the next video frame in the video segment is always faster than the writing operation of the current video frame by a second preset time. That is, the playing module 104 performs the reading operation of the next video frame before the second preset time of writing the current video frame, so as to pre-load the video frame, so as to eliminate the network delay. In this embodiment, the second preset time is 300 milliseconds. In other embodiments, the second preset time may be set as another time according to an actual network environment.
The pushing module 105 is configured to push a title to the user end 2 along with the video segment.
In this embodiment, the title is a title spoken by a teacher through voice in the video segment. And in the process of recording the video clip, the title information is mixed and coded into a video stream in a mode of media secondary information at a first preset time of playing the video clip. Therefore, the pushing module 105 pushes the title while playing the video segment, and the user terminal 2 can receive the title when playing the video segment to the first preset time, so that the time when the teacher speaks the title in the video segment is synchronized with the time when the user terminal 2 displays the title.
In this embodiment, when the video stream is decoded and played to the first preset time, the user side 2 receives and analyzes the secondary media information corresponding to the title, and displays the title on the playing interface of the video segment played on the display screen according to the secondary media information, so that the user can interactively answer the title.
In this embodiment, the title may be displayed on the playing interface of the user terminal 2 in the form of characters, patterns or animation. For example, the choice questions displayed by the playing interface include three choices of words "which choice below is fruit" and A, B, C, wherein, the choice A is a pattern of a cat, the choice B is a pattern of an apple, and the choice C is a pattern of a dog.
In this embodiment, the first preset time is the sum of the answer time and the stream pushing time of the next video segment to be played. Preferably, the first preset time is 8 th from last. That is, the pushing module 105 pushes the title with the video stream when the video segment is played to the 8 th last second. Thus, the time when the teacher made the question in each video clip is also the time when the video clip is played to the 8 th last second. Wherein, 7 seconds is the answering time of the student user, and 1 second is the time for the playing module 104 to push the stream of the next video clip to be played.
The receiving module 106 is configured to receive the user response to the topic transmitted by the user terminal 2.
In this embodiment, the user can answer the question in a third preset time by touch selection, text input, voice input, or other manners. And the third preset time is less than the first preset time. Preferably, the third preset time is 7 seconds.
The receiving module 106 receives the non-voice answer to the question from the user terminal 2 within the third preset Time based on a signaling service of WebRTC (Web Real-Time Communication). The non-voice answer at least comprises a touch option and input words. It should be noted that, when the non-voice answer is a touch option, a plurality of options to be selected are displayed on the play interface of the user side 2 based on the media secondary information, so that the user can select the options through the touch display screen. And when the non-voice answer is the input characters, displaying an input interface on the playing interface of the user end 2 based on the media secondary information for the user to input the characters by handwriting or a keyboard.
In this embodiment, the receiving module 106 further obtains the user's voice answer to the topic transmitted by the user terminal 2 within the third preset time based on an external rendering interface.
The receiving module 106 collects the audio transmitted by the user terminal 2 through the external rendering interface to obtain the voice response of the user to the title, and renders the voice response.
The analysis module 107 is configured to compare the answer of the user to the question with a preset answer, and determine whether the answer of the user is correct.
In this embodiment, the question bank stored in the memory 20 further includes a preset answer for each question. For the non-voice answer, the analysis module 107 determines whether the touch options or the input characters corresponding to the non-voice answer are the same as the preset answer, and determines that the user answers correctly when the touch options or the input characters corresponding to the non-voice answer are the same as the preset answer. And when the touch options or the input characters corresponding to the non-voice answers are different from the preset answers, judging that the user does not answer correctly.
For the voice answer, the analysis module 107 receives the collected real-time user voice uploaded by the user terminal 2 in real time to obtain the voice answer of the user to the question, identifies the voice answer of the user to determine the voice answer of the user, and performs semantic comparison analysis on the identified voice answer and a preset answer. When the semantic meaning of the recognized voice answer is the same as the semantic meaning of the preset answer, the analysis module 107 determines that the user answers correctly. When the semantic meaning of the recognized voice answer is different from the semantic meaning of the preset answer, the analysis module 107 determines that the user does not answer correctly.
It should be noted that the user needs to complete answering within the third preset time, and if the receiving module 106 does not receive the answer of the user to the question within the third preset time, the analyzing module 107 determines that the user does not answer correctly.
The playing module 104 is further configured to play the next video segment according to the preset sequence when the user answer is determined to be correct.
In this embodiment, when the user answer is determined to be correct, the playing module 104 forwards the next video segment containing the title to the user terminal 2 for playing. And the plug-in time is the difference value between the first preset time and the third preset time, so that the user can watch the subsequent teaching video immediately after answering the question. Meanwhile, as the last frame image of the video segment corresponding to each topic is the same as the first frame image of the video segment corresponding to the next topic, the playing of the next video segment and the playing of the video segment are in seamless connection visually, and the visual effect of real lecture is achieved.
The playing module 104 is further configured to play the parsed video segment for parsing the title seamlessly when it is determined that the user does not answer correctly.
In this embodiment, when it is determined that the user does not answer correctly, the playing module 104 pushes the analytic video segment for analyzing the title to the user end 2 for playing. And the plug-in time is the difference value between the first preset time and the third preset time, so that the user can immediately watch the teaching video for analyzing the question after answering the wrong question. Meanwhile, as the first frame image of the analysis video segment corresponding to each topic is the same as the last frame image of the video segment containing the topic, the seamless connection is formed between the playing of the analysis video segment and the playing of the video segment in the view of vision, and the visual effect of real lecture is achieved.
The playing module 104 is further configured to play the next video segment seamlessly when the playing of the parsed video segment is completed. As the tail frame image of the analysis video segment corresponding to each topic is the same as the first frame image of the video segment corresponding to the next topic, the analysis video segment is in seamless connection with the next video segment in view of vision, and the visual effect of real lecture is achieved.
The optimization module 108 is configured to optimize the voice output during the playing of the video segment and the received user voice, so as to improve the accuracy of voice recognition and improve the user experience. In this embodiment, the optimization includes at least echo cancellation, volume gain, and noise suppression.
Further, the optimization module 108 is further configured to perform sound effect processing on the voice output during the process of playing the video clip and the received user voice, so as to improve the interest of the online classroom. In the present embodiment, the sound effect processing includes at least tone changing processing, reverberation processing, and stereo processing.
