Abstract

The invention provides a method for full-video marking, and relates to the field of playing methods of teaching videos. The method comprises the steps that (1) a whole video file to be marked is acquired, and speech signals in the video file to be marked are extracted; (2) the digital speech signals are recognized and converted into corresponding character signals; (3) the character signals are added into the video file where points to be marked are located so that the character signals can be displayed inside or outside a video interface when the video file is played. By carrying out full-video marking or set-point marking on a video to be played or a video being played, a more convenient and vivid previewing effect is provided for a video watcher, and complex operations caused when time points need to be remembered or memory play only can be achieved on one computer in the prior art are avoided.

Description

technical field [0001] The present invention relates to the field of video processing, mainly refers to content marking of videos of teaching courses, so as to quickly find the content to be played, and more specifically, relates to a method for full video marking.
