Embodiment 1

[0032] Please refer to Figure 1-2 This embodiment provides a jump navigation method for video playback, including: S1, dividing the video into multiple video sub-segments according to video features, the video features including video text; S2, making a text summary for each video sub-segment, And generate the corresponding time progress bar node and at least one corresponding text label in the playback interface 1, and jump to the corresponding time progress bar node when the corresponding text label is selected; S3, the video text includes video text summary and video text feature extraction ; Video text summary includes extracting all segments of the video sub-segment to which the current playback time point belongs, and categorizing the same type of sub-segments in the extracted segment under corresponding semantic text; video text feature extraction includes extracting from the current Extract multiple video text parameters from the video sub-segment to which the playback...

Embodiment 2

[0038] Please refer to Figure 1-2 This embodiment provides a jump navigation method for video playback. In the embodiment of the present invention, video features include video and audio; video and audio include video scene detection and video speaker ID matching; video scene detection includes extracting the current playback time The video and audio features of the video sub-segment to which the point belongs. The video and audio features include background music, laughter, and applause. The extracted video and audio features are classified under the corresponding matching text; background music is used to adjust the atmosphere in the video Music, inserted in the dialogue, can enhance the expression of emotions and achieve an immersive feeling for the audience; laughter and applause are usually a turning point in the video, and the video is adjusted according to the background music, laughter and applause Divide into multiple video sub-segments, and the video segmented into t...

Embodiment 3

[0040] Please refer to Figure 1-2 This embodiment provides a jump navigation method for video playback. In the embodiment of the present invention, video features include video images; video images include shot switching detection, and shot switching detection includes extracting the video subsegment to which the current playback time point belongs The video image features of the extracted video image features are classified into the corresponding matching text. Shot switching is a video content transition method. The purpose is to make the video content smoother. According to the camera switching, the video is divided into multiple video sub-segments to facilitate the control of the rhythm. Further, the video image also includes title page identification, the title page includes a PPT title page, and preferably a title page with a solid color background.

Abstract

The invention discloses a jump navigation method for video playing. The method comprises: segmenting the video into a plurality of video sub-segments according to the video features, performing text summary on each video sub-segment, generating a corresponding time progress bar node and at least one corresponding text label on a playing interface, and skipping to the corresponding time progress bar node after the corresponding text label is selected. According to the technical scheme, text summarization can be automatically carried out on each video sub-segment, the method is more automatic, time is saved, and the method can be used as an auxiliary tool for manual annotation. According to the technical scheme, the method is based on video content and cannot be affected by watching flow. According to the technical scheme, the video content is summarized, so that a video browser can quickly skip to interested content and fragments, the method is suitable for videos with most text contents such as speech, class and lecture, the labeling time is saved for video makers, and the browsing time is saved for audiences.

Description

Technical field [0001] The invention relates to the technical field of video playback, and in particular to a jump navigation method for video playback. Background technique [0002] Since there are often content that the user is not interested in in the video, during the video playback, the user often jumps back and forth while watching the video. Statistics show that users need to jump multiple times on average to find the desired jump destination. This means that users often jump to the wrong location, and then find the desired jump destination through multiple jump adjustments. [0003] The existing navigation methods in video playback are all jump navigation by selecting nodes set on the progress bar, and are not suitable for videos with mostly text content such as lectures, classrooms, and lectures. Summary of the invention [0004] In order to overcome the above-mentioned problems or at least partially solve the above-mentioned problems, embodiments of the present invention ...
