Detailed Description
The present invention will be further described below, and it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides an intelligent classroom screen recording system which comprises a teacher teaching terminal and a student teaching terminal;
the teaching terminal is provided with a teaching module, the teaching module is used for teaching a teacher in an intelligent classroom and provides a teaching mode, a same-screen mode and a question setting mode. In addition, other modes such as a selected student answering mode, a suggestive mode and the like can be provided. It should be noted that the teacher teaching terminal may be an intelligent device integrating a blackboard, a screen, and a host, and is installed in a blackboard area of a classroom.
The student terminal of giving lessons is equipped with the module of giving lessons, the module of giving lessons is used for supplying the student to carry out the class in wisdom classroom to provide mode of giving lessons, with screen mode and answer mode. In addition, other modes such as a quiz mode and the like can be provided.
When the teacher chooses to adopt the mode of giving lessons, the teacher terminal of giving lessons sends the instruction to the student terminal of giving lessons, and the synchronous mode of giving lessons that opens of student terminal of giving lessons is controlled, and at this moment, the student terminal of giving lessons forces the lock screen, can't use, and the student can only listen to lessons, can't operate the student terminal of giving lessons. In the teaching mode, the teacher can display courseware, key points and other conventional teaching operations on a screen of the teaching terminal.
When the teacher selects to adopt the on-screen mode, the teacher teaching terminal sends an instruction to the student terminal to control the student terminal to synchronously start the on-screen mode, and at the moment, the teacher terminal synchronizes the screen content of the student terminal to synchronize the screen content of the student terminal and the screen content of the teacher terminal to be synchronized in real time. In the same screen mode, the operation that the teacher can carry out is the same as the mode of giving lessons, and the main difference lies in that the teacher terminal of giving lessons can synchronize its screen content to the student terminal of giving lessons.
When the teacher chooses to adopt the question setting mode, the teacher teaching terminal sends an instruction to the student teaching terminal to control the student teaching terminal to synchronously start the question answering mode, at the moment, the teacher can give questions by using the question setting mode, the teacher teaching terminal synchronizes the questions to the student teaching terminal, and the students can freely answer the questions on the student teaching terminal;
the teacher teaching terminal is also provided with a teacher end screen recording module and a teacher end recording module, and the teacher end screen recording module and the teacher end recording module are used for respectively and synchronously starting screen recording and recording when the teacher teaching terminal starts a teaching mode, a same screen mode or a question answering mode until the teaching mode, the same screen mode or the question answering mode is closed, respectively obtaining a teacher end video file and a teacher end audio file and uploading the teacher end video file and the teacher end audio file to the server end;
the student class-giving terminal is also provided with a student terminal screen recording module and a student terminal recording module, and the student terminal screen recording module and the student terminal recording module are used for respectively starting screen recording and recording synchronously when the student class-giving terminal starts the answer mode until the answer mode is closed, and acquiring a student terminal video file and a student terminal audio file and uploading the video file and the audio file to the server terminal;
a server side: the server is respectively in communication connection with the teacher teaching terminal and the student teaching terminals and used for receiving teacher video files and teacher audio files obtained by the teacher teaching terminals and student video files and student audio files obtained by the student teaching terminals, fusing the teacher video files and the teacher audio files obtained by the teacher teaching terminals to obtain audio teacher video files, respectively fusing the student video files and the student audio files obtained by the student teaching terminals to obtain audio student video files corresponding to the student teaching terminals, and finally integrating the audio student video files corresponding to the student teaching terminals with the audio teacher video files to obtain intelligent class recording screen files corresponding to the student teaching terminals. Each student can obtain the corresponding intelligent classroom screen recording file through logging in the server.
It should be noted that, in the above-mentioned system, the teacher terminal of giving lessons and the student terminal of giving lessons are all subdivided into multiple mode of giving lessons and giving lessons, only the teacher terminal of giving lessons and the student terminal of giving lessons just can record the screen and record when having opened appointed mode, especially only the answer mode has been opened in the student terminal of giving lessons just records the student, can the final redundant fragment and the sound in the wisdom classroom record screen file that obtains of integration that can significantly reduce, avoid the effective information not concentrated in the record screen file, the circumstances that the sound is noisy, it has better quality to keep wisdom classroom record screen file.
In this embodiment, the teacher-side screen recording module records start timestamp and end timestamp information each time the teacher-side screen recording module starts screen recording and each time the teacher-side recording module starts recording, the server side fuses each teacher-side video file and each teacher-side audio file with the same start timestamp and end timestamp to obtain a sound teacher-side video file segment, and then splices all the sound teacher-side video file segments in time sequence to obtain a complete sound teacher-side video file;
the student end video recording module starts the video recording at every time and records the information of the start timestamp and the end timestamp, for the same student end, the server end fuses each section of student end video files and student end audio files with the same start timestamp and the same end timestamp to obtain the student end video file fragments with sound, and then splices all the student end video file fragments with sound according to time to obtain the complete student end video files with sound.
The server side is used for splicing the audio teacher-side video file and the audio student-side video file in time sequence, wherein the audio teacher-side video file and the audio student-side video file with the same starting timestamp and ending timestamp are spliced on the same picture, and therefore the intelligent classroom screen recording file is obtained through integration.
More specifically, in this embodiment, the student class attendance terminal stores voiceprint information of a corresponding user in advance, and the student end recording module identifies the voice of the user according to the prestored voiceprint information of the user and records only the voice of the user when recording is performed. Therefore, the student end recording module corresponding to each student end of class only records the sound of the corresponding student, so that the sound of a teacher and the sound of other students can be prevented from being recorded into the student end audio file corresponding to the student end of class, and the noise of the sound in the intelligent class screen recording file generated finally is avoided.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
