Problems solved by technology

[0002] For traditional recording and broadcasting video resources, when adding knowledge point indexes, the teacher needs to watch the video files of the courseware first, and then add knowledge point indexes according to the time corresponding to the knowledge points in the video, so as to perform fast positioning and playback, which is time-consuming , must also be completed by the teacher himself, because only the teacher knows which knowledge is important, wasting a lot of time and manpower

Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] figure 1 It is a flowchart of a method for automatically realizing knowledge point index generation in an embodiment of the present invention; refer to figure 1 , the method includes:

[0033] S101: Obtain the start time of video recording by the recording server;

[0034] It should be noted that when video recording is performed, the teacher usually uses a PC to explain the courseware. In order to facilitate the acquisition of knowledge points, the subject of execution of the method usually chooses the PC used by the teacher.

[0035] S102: Grab the knowledge points of the current page of the courseware in real time, and record the current page turning time when...

Abstract

The invention discloses a method and device for automatically realizing knowledge point index generation, and relates to the technical field of video processing. The invention obtains the start time of video recording by a video recording server, and captures the knowledge points of the current page of courseware in real time. When a change occurs, record the current page-turning time, determine the knowledge point interval corresponding to each knowledge point according to the recorded page-turning time and start time, and use the knowledge point and the corresponding knowledge point interval as the knowledge point index to realize In order to automatically generate the index of knowledge points, it saves time and manpower.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and device for automatically realizing knowledge point index generation. Background technique [0002] For traditional recording and broadcasting video resources, when adding knowledge point indexes, the teacher needs to watch the video files of the courseware first, and then add the knowledge point indexes according to the time corresponding to the knowledge points in the video, so as to perform fast positioning and playback, which is time-consuming , must also be completed by the teacher himself, because only the teacher knows which knowledge is important, wasting a lot of time and manpower. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method and device for automatically implementing knowledge point index generation that overcome the above problems or at least partially solve the above probl...
