Embodiment Construction

[0027] Such as figure 2 As shown, it is a schematic diagram of adopting the technical solution of the present invention, when the cataloging operator is in the position When observing the video, the operator can obtain the video preview information through the observation window corresponding to the position, and obtain a rough impression of the video. At the same time, the audio and video information corresponding to the current position and the adjacent frame image information displayed frame by frame can also be obtained. Thus, the operator can get precise information about the video.

[0028] The present invention pre-sets the display number of preview information frames according to the screen resolution of the cataloging operator, and the number of preview frames displayed in the preview window of the preview module is fixed. In this way, when the operator adjusts the preview display ratio to the position , under the same number of preview frames, you can get more d...

Abstract

The invention provides a method and system for categorizing a video aiming at the problems that the efficiency is low, the cost is high, and the preview observation accuracy can not be adjusted in the existing method for manually categorizing the video. The method comprises the following steps: 1, loading the video, acquiring the running time and the format information of the video and determining the length of a timer shaft; 2, determining an existing observation position of the video, decoding and displaying an adjacent frame neighboring the existing observation position, and updating the adjacent frame when the existing observation position of the video is changed; and 3, determining an initial preview display scale, decoding and displaying a preview frame, and updating the preview frame when the preview display scale or the existing observation position is changed. A categorization operator uses the method and system provided by the invention to browse the preview frame of the video in advance without watching the video completely; and then the adjacent frame is observed after preliminary positioning is carried out, thus the categorization positioning is more accurate, the categorization efficiency is improved, the labor intensity of categorization work is reduced, and a user can be preferably helped to process and use video resources in time.

Description

technical field [0001] The invention relates to the technical field of video data processing, in particular to a video cataloging method and system. Background technique [0002] As an asset, video programs and materials have been widely recognized by the media and the industry for their huge economic value. With the upgrading of Internet bandwidth and the development of video transmission technology, the wide application of video on the Internet has become a reality. To get the most out of these media assets, the video content must first be cataloged. like figure 1 As shown, in the technical solution adopted by traditional video cataloging, the user can only obtain the audio and video information contained in the video frame by frame. Concentrate on it all the time, and the labor intensity is high. The operator finds the content that needs to be marked by watching the video uninterruptedly. When the operator finds the content that needs to be marked, he pauses the video...
