Jump navigation method and device for video playback

Abstract

The embodiment of the invention provides a video playing skip navigation method and equipment. The video playing skip navigation method comprises the steps of dividing a video into a plurality of video subsegments according to a video text; Determining a video sub-segment to which the current playing time point belongs, extracting a video text feature vector of the video sub-segment to which the current playing time point belongs, and extracting a video image feature vector of the video sub-segment to which the current playing time point belongs; Inputting the current user information, the video text feature vectors of the video sub-segments to which the current playing time point belongs and the video image feature vectors into a trained neural network, and outputting each video sub-segment as a probability value of skipping to the target video sub-segment, so that the current user selects the corresponding video sub-segment for skipping according to each probability value. Accordingto the method and the device, dynamic skip navigation can be realized according to different users, and no static navigation point needs to be inserted into each video during video production, so thatthe workload of video production is reduced.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of video playback, and more specifically, to a jump navigation method and device for video playback. Background technique [0002] Since there are often content that users are 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 2.2 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 static video navigation, such as inserting navigation points at fixed moments in the video. This static video navigation method has obvious defects: (1) There are a large number of users watching the same For a video, users have different points of interest. This static video navigation method cannot realiz...

[0003] The navigation method in the existing video playback at present is all static video navigation, such as inserting a navigation point at a fixed moment point in the video. This static video navigation method has obvious defects: (1) there are a large number of users watching the same video. For a video, the points of interest between users are different, and this static video navigation method cannot realize dynamic jump navigation according to different users; reduce the workload of video production
