Example Embodiment

[0068] The main inventive idea of ​​the present invention is to segment the video by using public intelligent video technologies (such as motion detection, color search, face detection, vehicle detection, human detection, wandering detection, cross-line detection, etc.) to extract the user The video segment of the content of interest, and save the information of the video segment to the database or attached file; then organize these video segments in chronological order to form a logical video file, and realize the normal playback control function of the logical video file , You can also smoothly switch the playback control between the video clip and the original video file, thereby reducing the number of video frames that need to be watched, allowing users to concentrate on important screens and improving the efficiency of video browsing.

[0069] Such as figure 1 As shown, this figure describes the flow of the video preprocessing and playback method provided by the present inven...

Abstract

The invention relates to the technical field of multimedia, in particular to a video preprocessing and playing method and system. The method comprises the following steps of: (1) extracting video segments including contents that users are interested in through video segmentation by using a public intelligent video technology; (2) storing information of the video segments into a database or an accompanying document; and (3) organizing the video segments in chronological order into a logical video file. The video preprocessing and playing method and system achieve the function of conventional playing control of the logical video file, and can be used for smoothly switching the playing control between the video segments and an original video file, thereby reducing the number of video frames required for watching, allowing the users to concentrate on important frames, and improving the video browsing efficiency.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and system for video preprocessing and playing. Background technique [0002] With the development of computer technology and network technology, the amount of video data produced and obtained by people in various ways is increasing, and video has gradually become the main media form in the field of information processing. How to quickly browse videos has become a hot issue in multimedia technology research. [0003] The traditional video browsing method is to use a conventional video player to play video files. In order to reduce the viewing time, you can use the fast playback function provided by the player. In order to improve efficiency, you can quickly locate the location of interest by dragging the progress bar. This method is suitable for viewing a small amount of video files, but when a large number of videos need to be browsed, the defect of this browsing m...
