Description

Technical Field

[0001] This invention relates to the field of education and training technology, specifically to a classroom teaching video recording management system and management method. Background Technology

[0002] The widespread application of internet technology has gradually made it a primary source of information for people, enriching their learning, working, and lifestyles. Simultaneously, with the development of streaming media technology, traditional teaching methods in the education field have also been upgraded and improved. Online classrooms, a new type of education leveraging the internet, involve systematic teaching and communication between students and teachers, and between students and educational organizations, using various media. Specifically, it involves recording or live-streaming courses online for students to watch and learn from. The recording system combines and organizes the audio and video (live or recorded) in real time, then publishes the organized audio and video to the teaching platform, allowing students to recreate the classroom experience by clicking and playing the audio and video.

[0003] The existing classroom teaching video recording and management methods mostly involve recording all day long and then manually dividing and editing the videos by class. The recorded videos are saved and used after a simple review by the auditors. There is no effective means to automatically distribute the divided and categorized recorded videos to the corresponding teachers for video inspection, editing, and maintenance. This results in poor video presentation quality and chaotic video management, which is not conducive to students' online learning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a classroom teaching video recording management system and method. When applied, it can automate the recording of each class session and automatically send the recorded teaching videos to the corresponding teachers for video aggregation and processing, thereby improving the management effectiveness of classroom teaching videos and enabling students to quickly find the classroom teaching videos they need.

[0005] The technical solution adopted in this invention is as follows:

[0006] A classroom teaching video recording and management system includes a recording camera, a recorder, a signal controller, a network switch, and a backend server. The recording camera and recorder are used for recording classroom teaching videos in corresponding classrooms. The signal controller is used for signal reception, processing, and on / off control of the recording camera and recorder in the corresponding classroom. The network switch is used for information exchange between the signal controller and the backend server. The backend server includes a course import unit, an ID verification unit, a time management unit, a video receiving unit, a teacher management unit, a video review unit, a student management unit, and a storage unit. The course import unit is used to import the timetable information of the corresponding class. The ID verification unit is used to verify the ID information of the signal controller against the corresponding classroom. The time management unit uses the timetable information imported by the course import unit to confirm the working time of the recording camera and recorder. During a given period, the corresponding signal controller controls the switching on and off of the recording camera and recorder according to the working time period confirmed by the time management unit. The video receiving unit receives classroom teaching videos uploaded by the corresponding signal controller. The teacher management unit sends the classroom teaching videos received by the video receiving unit to the corresponding teacher's end for processing, and then sends the processed classroom teaching videos to the video review unit. The video review unit sends the processed classroom teaching videos to the reviewer's end for review, and sends the approved classroom teaching videos to the storage unit for storage. Classroom teaching videos that fail the review are returned to the teacher management unit, which then returns them to the corresponding teacher's end for reprocessing. The student management unit handles access requests from the student's end and retrieves the corresponding classroom teaching videos from the storage unit according to the student's access request, sending them to the student's end.

[0007] As a preferred embodiment of the above technical solution, the video information recorded by the recording camera and the audio information recorded by the audio recorder are marked with synchronized timestamps. The signal controller integrates the video information and audio information into a classroom teaching video based on the synchronized timestamps, and marks the recording time period of the classroom teaching video according to the synchronized timestamps. Then, the classroom teaching video is combined with the recording time period information and its own ID information and sent to the video receiving unit of the backend server.

[0008] As a preferred embodiment of the above technical solution, the ID verification unit extracts the ID information of the signal controller, determines the corresponding class, and marks the class information corresponding to the classroom teaching video.

[0009] As a preferred embodiment of the above technical solution, the teacher management unit sends the classroom teaching video to the corresponding teacher's end for processing based on the class information, recording time period, and the corresponding class's timetable information. The title of the classroom teaching video processed by the teacher's end includes teacher name information, class information, subject information, and course chapter information in a set format. The storage unit categorizes and stores the approved classroom teaching videos according to their titles.

[0010] As a preferred embodiment of the above technical solution, the timetable information includes class information, subject information, course time period information, and teacher information. The ID verification unit determines the corresponding signal controller based on the class information, the time management unit determines the course recording time period information of the corresponding class based on the course time period information, and the background server sends the course recording time period information of the corresponding class to the corresponding signal controller. The signal controller controls the recording camera and the recorder to work during the course recording time period.

[0011] As a preferred embodiment of the above technical solution, the backend server further includes an audit record unit, which is used to record the audit results from the audit personnel.

[0012] A method for managing classroom teaching video recordings includes the following steps:

[0013] S1. Obtain the timetable information of the corresponding class and the signal controller ID information of the classroom of the class, parse the timetable information, obtain the course recording time period information of the corresponding class, and send the course recording time period information to the corresponding signal controller.

[0014] S2, the signal controller controls the recording camera and recorder to record classroom teaching videos during the course recording period, and sends the recorded classroom teaching videos, recording time period information and its own ID information to the backend server;

[0015] S3. The backend server determines the corresponding class information based on the ID information, and determines the teacher corresponding to the classroom teaching video based on the corresponding class information, recording time period information and course schedule information. The classroom teaching video is then sent to the corresponding teacher's end for processing. The title of the classroom teaching video after processing by the teacher's end includes teacher name information, class information, subject information and course chapter information.

[0016] S4. Send the classroom teaching video processed by the teacher to the reviewer for review. If the review is successful, the classroom teaching video will be classified and stored in the storage unit according to the teacher's name information, class information, subject information and course chapter information. If the review is unsuccessful, it will be sent back to the corresponding teacher for reprocessing.

[0017] S5. Students access the backend server and retrieve the corresponding classroom teaching videos from the storage unit for viewing based on the teacher's name, class, subject, and course chapter information.

[0018] As a preferred embodiment of the above technical solution, the signal controller is equipped with a teacher information input unit and a manual switch control unit. The teacher inputs teacher information through the teacher information input unit and manually controls the recording time of the camera and recorder through the manual switch control unit. The classroom teaching video recorded during the manually controlled recording time is integrated with the input teacher information and signal controller ID information and then sent to the backend server. The backend server sends the classroom teaching video to the corresponding teacher's end for processing based on the teacher information.

[0019] As a preferred embodiment of the above technical solution, in step S3, the teacher's processing of the classroom teaching video includes checking the video, editing the video, and adding a video title according to a set format.

[0020] As a preferred technical solution, if a teacher finds that a video is not their own classroom teaching video when reviewing it, they can forward the video to another teacher.

[0021] The beneficial effects of the present invention are:

[0022] This invention enables automated segmented recording of classroom lessons and automatically identifies the class, subject, and teacher corresponding to each recorded lesson video. It can also send the classroom videos to the respective teachers for video processing and subject / chapter organization, allowing students to quickly find the videos they need for review after class based on teacher, class, subject, and chapter information. Furthermore, when teachers process the classroom videos, they can edit them to make them more engaging and improve the presentation, thus benefiting students' online learning.

[0044] Example 2:

[0045] This embodiment provides a method for managing classroom teaching video recordings, such as... Figure 2 As shown, it includes the following steps:

[0046] S1. Obtain the timetable information of the corresponding class and the signal controller ID information of the classroom of the class, parse the timetable information, obtain the course recording time period information of the corresponding class, and send the course recording time period information to the corresponding signal controller.

[0047] S2, the signal controller controls the recording camera and recorder to record classroom teaching videos during the course recording period, and sends the recorded classroom teaching videos, recording time period information and its own ID information to the backend server;

[0051] In its application, recorded lectures can be recorded unilaterally by the teacher, allowing students to watch and learn at their leisure. This conveniently aligns with students' schedules, preventing some students from missing lessons due to various reasons, and ensuring that the knowledge they learn is up-to-date while maintaining flexibility in their learning time. Everyone knows that the teaching of a renowned teacher is crucial for student learning. However, a renowned teacher cannot explain everything to every student. Recorded lectures easily solve this problem. Each lecture can be easily recorded, and by watching the recorded lectures, every student can learn easily and effortlessly. This achieves a high degree of uniformity in learning content and consistent teaching quality. Some courses do not require repeated explanations from the teacher, but are only addressed by students who are not focused or have slower comprehension. Watching recorded lectures effectively helps these students, allowing them to learn and listen repeatedly, reducing unnecessary repetitive work for the teacher. Employing a distributed storage and centralized management approach, video resources can achieve higher and more reliable performance at a lower cost, with less manpower and lower energy consumption. Furthermore, the use of big data algorithms makes management smoother and more user-friendly.
