Intelligent education video service system based on cloud computing and mobile terminal and operation method thereof

Abstract

The invention relates to an intelligent education video service system based on cloud computing and a mobile terminal and an operation method thereof. The intelligent education video service system comprises a multi-platform terminal, a communication network, a front-end processing module, a short video module, a first intelligent auditing module, a live broadcast module, a second intelligent auditing module, an interactive learning and testing module, a data analysis module and a cloud computing module. The short video module has strong capabilities of rapid uploading, transcoding, storage, distribution and the like, integrates functions of shooting, special effects, filtering, editing, synthesis, local compression, uploading, playing, real-time interactive test questions and the like, and realizes editing, manufacturing and publishing of one-stop education short videos. The live broadcast module displays auxiliary information such as student answering statistical percentage and answering time in real time, and teachers dynamically adjust teaching plans or explain and consolidate detailed knowledge points according to displayed real-time statistical results.

Description

technical field [0001] The invention relates to an intelligent educational video service system based on cloud computing and mobile terminals and an operating method thereof, belonging to the technical fields of mobile education, network mobile communication and cloud service platforms. Background technique [0002] With the rapid development of the information industry, the increasing scale of the Internet, and the continuous improvement of 4G and 5G mobile communication networks, various applications based on the mobile Internet are closely connected with people's work and life. [0003] In June 2018, the China Internet Network Information Center released a report that the number of mobile Internet users in my country reached 788 million, accounting for 98.3% of the total Internet users, and the proportion of students was as high as 24.8%; the number of mobile online education users was 142 million. The possession rate of mobile terminal devices such as smartphones and tab...

AI Technical Summary

Problems solved by technology

However, mobile live broadcast also has problems that affect its teaching effect

The first is the signal problem

During mobile live broadcast, if the mobile Internet signal reception in the area is poor, it will have a serious impact on the live broadcast, making viewers unable to watch the live video smoothly

The second is the field problem

Mobile live broadcasting has lowered the threshold for live broadcasting, but teachers cannot perform operations such as changing the focal length and switching between teachers and blackboard writing like traditional live broadcasting. Teachers can only perform real-time comment barrage and Lianmai during live broadcasting. interactive

The third is a matter of time

However, this patent has the following defects: 1. During the live teaching, the teacher needs to constantly check the number of statistical comments and bullet screens, and understand the students' mastery of the classroom content according to the comments, and cannot perform data analysis intelligently in real time, which greatly It distracts the teacher's attention during lectures and affects the continuity of classroom teaching. Teachers cannot devote themselves to teaching and cannot effectively detect students' mastery of teaching knowledge points in real time.

2. Although the system provides a live playback function, a normal class lasts nearly an hour. When reviewing and reviewing, students need to spend time dragging and dropping the playback progress bar to find the time point of knowledge points.

It is not convenient for students to look back and record knowledge points

3. During the teaching process, teachers can only communicate with students in text and voice, but cannot interact with video, and cannot communicate face-to-face with students in the classroom as in reality.

4. The homework submitted by students after class is just a simple answer, which cannot effectively help students to consolidate and review the knowledge points of the course

The so-called intelligent correction is only an intelligent judgment on the choice, and it cannot be intelligently corrected for all the questions, which will eventually increase the workload of teachers after class

5. During the mobile live broadcast, the system does not have a content security audit function. Although the users are all students, they cannot effectively audit and filter the students' interactive speeches and submitted assignments, and there will be various dangers that are difficult to control factor
