The invention provides a device for conducting rapid video marking. The device is applied to the field of teaching video playing processing. The device comprises a dotting module, a pickup module, a voice recognition module and a control processing module, wherein the dotting module is used for selecting to-be-marked points in a playing video, the pickup module is used for collecting video sections in front and at back of the to-be-marked points and extracting voice signals in the video sections, the voice recognition module is used for recognizing the voice signals and converting the voice signals into corresponding character signals, and the control processing module is used for attaching the character signals to the video where the to-be-marked points are located and conducts output display. By means of the device, full video marking or point setting marking is carried out on a to-be-played video or the playing video, more convenient, faster and more vivid preview effects are provided for a video viewer, and complex operation that in the prior art, time points need to be remembered or memory playing can only be carried out on one computer is 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 device for fast video marking. Background technique [0002] With the development of Internet technology, the modern teaching mode is no longer limited to the traditional on-site practical teaching. People can learn more without listening to lectures on the spot, but can learn according to their own time and place without being limited by time and place. Situation to learn through video. For example, remote teaching or video self-study can be carried out. However, these are all based on the video recording of the course, that is, the on-site teaching needs to be video-recorded first, so that those who need to learn can learn freely at any place and time. [0003] However, in reality, there is such a situation that the video time of a certain ...
