Video teaching system and video teaching method

Abstract

The invention relates to a video teaching method, which based on a video teaching system. The video teaching system comprises a storage module, a user interface module, a video switching module, a video calling module and a video synchronizing module. The storage module is used for storing course video; the user interface module is connected with a user terminal; when receiving the play mode switching command from the user terminal, the user interface module acquires the information of the current play position of a current course video, providing the video synchronizing module with the information of the current play position of the current course video, extracting the information of the target play mode from the play mode switching command and providing the video switching module with the information of the target play mode; and the video switching module switches the current course video to the target course video according to the information of the target play mode. The system and method provided by the invention can bring more course watching modes for course watching users, thereby bringing better user experience.

Description

technical field [0001] The invention relates to the field of video teaching, in particular to a video teaching system and method. Background technique [0002] With the development of Internet application-related technologies, the era of high-definition video is gradually coming. At present, the following video teaching methods have been put into use: using Media or Real type audio and video solutions for online teaching (teaching); using streaming media provided by FMS, and so on. For the latter, due to the constraints of technologies such as streaming media compression and transmission, FMS can only provide smaller streams and smaller-sized videos. [0003] In the past, due to the limited display area of ​​the page and the constraints of previous technology and network conditions, only small-sized videos (lower resolution) could be provided. Since the small-sized video only occupies a small part of the screen area and cannot display a lot of content, the handouts are usu...

AI Technical Summary

Problems solved by technology

Since the small-sized video only occupies a small part of the screen area and cannot display a lot of content, the handouts are usually displayed in an area other than the video in the form of text and pictures. Otherwise, if the handouts are also incorporated into the video, the video The resolution is low, it is difficult for users watching the instructional video to see the lecture content in the video clearly, and on the other hand, most of the display area on the screen is wasted
