Embedded network live broadcast video stream hardware system and method

Abstract

The invention discloses an embedded network live broadcast video stream hardware system and method, and the system comprises a video collection end, a data analysis module, and an adjustment module, the video collection end is used for collecting multi-party video data through a network camera, the data analysis module is used for carrying out the further analysis according to the collected video data, and the adjustment module is used for adjusting the adjustment module. The adjusting module is used for adjusting the equipment according to an analysis result, the data analysis module comprises a teacher behavior analysis module and a student behavior analysis module, the teacher behavior analysis module is used for analyzing behavior characteristics of a teacher giving a lesson, the student behavior analysis module is used for analyzing behavior characteristics of students giving the lesson, and the teacher behavior analysis module is used for analyzing the behavior characteristics of the students giving the lesson. The teacher behavior analysis module comprises a touch sensing sub-module, the student behavior analysis module comprises a gaze sensing sub-module and a time recording sub-module, and the system has the advantage of being more comprehensive in design.

Description

technical field [0001] The invention relates to the technical field of network live broadcast, in particular to an embedded network live broadcast video stream hardware system and method. Background technique [0002] There are various teaching methods for live broadcast open courses in colleges and universities, including live broadcast platform teaching, classroom recording and broadcast teaching, classroom live teaching, etc. For live broadcast platform teaching, teachers do not need to enter the classroom, but only need equipment with audio and video input. The disadvantage of teaching is that writing on the blackboard requires an external handwriting board, and the classroom atmosphere is insufficient; for classroom recording and broadcasting, the video of the teacher's class in the classroom is recorded and edited and uploaded, and students can watch it online at any time. Uploading; for classroom live teaching, teachers teach in the classroom, the webcam broadcasts ...

AI Technical Summary

Problems solved by technology

[0002] There are many teaching methods for live broadcast open classes in colleges and universities, including live broadcast platform teaching, classroom recording and broadcast teaching, classroom live broadcast teaching, etc. For live broadcast platform teaching, teachers do not need to enter the classroom, and only need equipment with audio and video input The disadvantage of teaching is that blackboard writing needs to be connected to an external handwriting board, and the classroom atmosphere is insufficient; for classroom recording and broadcasting, the teacher’s video in the classroom is uploaded after recording and editing, and students can watch it online at any time. Upload; For classroom live teaching, the teacher is in the classroom, the webcam is live broadcasting and streaming to the server, and the students can attend the class online by accessing the server. The disadvantage is that it is difficult for the teacher to interact with the students for the current equipment technology

[0003] Through the survey, it was found that more people prefer the way of classroom live broadcast teaching, because this method can more comprehensively simulate the way of offline teaching. Teachers can write on the blackboard, and students have a strong sense of identity. However, the current classroom live broadcast The teaching method is limited by equipment defects, and there are still many problems such as teachers cannot interact with students in real time, the video angle is single and not immersive enough, and the load capacity of the server is high, etc. At the same time, the teacher's class rhythm cannot be gradually advanced according to the students' performance , the teacher can't grasp the students' class situation very well, the teaching quality is not high, and the live broadcast screen cannot be edited and switched in real time. Therefore, it is necessary to design a more comprehensive hardware system and method based on embedded network live video stream of
