In the disclosed embodiment, one multi-scene blackboard 14 and a classroom camera 15 connected to the multi-scene blackboard 14 are installed in each remote classroom. The classroom camera 15 is used to capture a first video of a lecture student asking questions in a remote classroom. Each display module in the multi-scene blackboard 14 displays a video of one participant in the online answer. For example, a first video of a lecture student quiz in a classroom, a video of a lecture teacher, and/or a video of an assistant teacher.

The aspect ratios of the first display module and the second display module are both greater than 1, which can be understood that the first display module and the second display module are vertical display screens, for example, as shown in fig. 2, the first display screen 141, the second display screen 142, the third display screen 143 and the fourth display screen 144, where the aspect ratios of the first display screen 141, the second display screen 142 and the third display screen 143 are all greater than 1, are vertical display screens respectively, the aspect ratio of the fourth display screen 144 is less than 1, and the fourth display screen 144 is a horizontal display screen.

For any one multi-scene blackboard 14 of the multiple sets of multi-scene blackboards 14, the server 11 is configured to:

receiving a first video acquired by the multi-scene blackboard 14 through the classroom camera 15, and transmitting the first video to the first client 12, wherein the first video comprises current questioning information of students in class;

receiving to-be-solved information returned by the first client 12 in response to the current question information of the first video;

Further, the first client 12 is configured to receive the first video; responding to receiving an instruction to be solved for the current question information, and acquiring a first time point for receiving the instruction to be solved; and determining the starting time point and the first time point as the information to be solved, and sending the information to be solved to the server 11.

The to-be-solved instruction comprises: keyboard commands, mouse commands, and/or gesture commands in video. For example, after watching a first video including current question information, the assistant teacher cannot answer the current question information, and then issues a to-be-solved instruction through a keyboard instruction.

Since the question and answer process is a complete question and answer process. If the assistant teacher can not answer the question, the first time point of receiving the instruction to be solved sent by the assistant teacher is taken as the time point when the question ends at the assistant teacher.

Therefore, the server 11 is configured to obtain, in response to the to-be-solved information being the start time point and the first time point, the to-be-solved video segment from the first video based on the start time point and the first time point.

The obtaining the video segment to be solved from the first video based on the start time point and the first time point may be understood that the start time point is taken as a start time point of capturing the first video, and the first time point is taken as an end time point of capturing the first video, so as to obtain the video segment to be solved.

In the embodiment of the disclosure, the server 11 makes the questions that the assistant teacher cannot answer into the video segments to be solved, and transmits the video segments to the teaching teacher, and the teaching teacher answers the questions. The teaching teacher only solves the problem that the assistant teacher cannot solve, avoids the time consumed by the teaching teacher to watch the video of the problem solved by the assistant teacher, reduces the video amount watched by the teaching teacher, saves the watching time of the teaching teacher, shortens the delay time of on-line answering, and improves the answering efficiency of the teaching teacher. Relatively, the student amount of giving lessons and giving teachers on-line answering questions can be improved.

In another specific embodiment, the first client 12 is configured to receive the first video; and responding to the current question information of the first video, obtaining a second video for the assistant teacher to answer the current question information, and transmitting the second video to the server 11.
