Embodiment 1

[0077] figure 1 It is a schematic diagram of the implementation environment of an online classroom video display method provided in an example of the implementation of this application, see figure 1 , the implementation environment may include: at least two student terminals 101 , one teacher terminal 102 and one server terminal 103 .

[0078] The server 103 is directly or indirectly connected to each student terminal 101 and teacher terminal 102 through wired or wireless communication. Both the student terminal 101 and the teacher terminal 102 can be smartphones, tablet computers, notebook computers, desktop computers, smart TVs, etc., but are not limited thereto.

[0079] The student terminal 101 installs and runs an online live broadcast application program for students to participate in the online classroom. The student terminal 101 receives the teacher's video data forwarded by the server terminal 103 so that students can watch the teacher's lecture through the student t...

Embodiment 2

[0084] figure 2 It is a flow chart of an online classroom video display method provided in Embodiment 2 of the present application, and the method is applied to the student terminal. see figure 2 , the method includes the following steps:

[0085] 201. Obtain a student video stream captured by a camera on a student terminal, where the student video stream includes video images of students participating in an online class.

[0086]The student terminal is the student user terminal in the online classroom system. In an online classroom with multiple students, each student uses a student terminal to access the online classroom system, and different students use different student terminals to access the online classroom system. During the online class, the student end uses the camera to collect video images of students participating in the online class, and then obtains the student video stream captured by the camera. After the online class starts, students can adjust the ang...

Embodiment 3

[0102] image 3 It is a flow chart of an online classroom video display method provided in Embodiment 3 of the present application. This method is applied to the server, see image 3 , the method includes the following steps:

[0103] 301. For each of the at least two student terminals, receive a student video stream and a seriousness score from the student terminal.

[0104] During the online class, the server receives student video streams from multiple student terminals in real time, and periodically receives seriousness ratings from multiple student terminals. The student video stream is collected by the corresponding student terminal, and the student video stream includes video images of students participating in the online class. The seriousness score is determined by the corresponding student terminal based on the student's video stream, and the seriousness score is used to represent the seriousness of the student's participation in the online class.

[0105] 302. Fo...

Abstract

The embodiment of the present application provides a video display method, device, system and storage medium for an online classroom. When the method is applied to a student terminal, it includes: acquiring a student video stream including video images of students participating in an online classroom; Collect video frames from the video stream; input the video frames into the pre-trained scoring model to obtain a seriousness score, where the seriousness score is used to represent the seriousness of students participating in the online classroom; send the student video stream and seriousness score to the server; receiving the aggregated video stream from the server, wherein the aggregated video stream is generated by the server by performing video stream aggregation on student video streams sent by multiple first student terminals according to the earnestness ratings sent by at least two student terminals, the first student The terminal is the student terminal that sends higher seriousness scores; based on the aggregated video stream, the student video corresponding to the student video stream is displayed. This solution can improve the learning atmosphere of multi-student participation in online classrooms.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video display method, device, system and storage medium for online classrooms. Background technique [0002] With the continuous development of Internet technology and the popularization of smart terminals, distance education is becoming more and more common, and online classroom is an important form of distance education. When teaching in an online classroom, the student terminal collects student videos and sends them to the server, and the teacher terminal collects teacher videos and sends them to the server. Display the teacher's video, and then teachers and students can interact through video to realize distance teaching. [0003] At present, when a teacher is teaching multiple students at the same time through an online classroom, the server will not only forward the teacher's video to the students, but also forward the student videos collected by each student...
