Video fast forward/fast backward speed self-adaptive regulating method based on semantic content

Abstract

The invention relates to a video fast forward / fast backward speed self-adaptive regulating method based on semantic content. The video fast forward / fast backward speed self-adaptive regulating method comprises the following steps: firstly, extracting a shot semantic set of each shot by taking the shot as a unit, then, obtaining semantic context of a video shot in a supervisory manner, and representing the context through a context tag tree; then, regulating weight of the shot by the context tag tree of a video; determining the fast forward / fast backward rate of each shot according to the weight of the shot. The video fast forward / fast backward speed self-adaptive regulating method based on semantic content disclosed by the invention can be used for regulating the video fast forward / fast backward speed in a self-adaptive manner according to the video semantic content and the context of each shot to help a user to quickly skip uninterested content; moreover, the interested content is not missed due to excessively high skip speed, so that convenience is provided for the user.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a video fast-forward / rewind speed self-adaptive adjustment method based on semantic content. Background technique [0002] When users watch a video, they will encounter the situation that they need to quickly skip the uninteresting part, so the video playback function on the video playback software or the Internet usually provides the user with the function of fast forward and rewind, and the user can also set it by himself. Fast forward or rewind speed. [0003] However, today's fast forward and rewind functions require users to set the speed of fast forward and rewind, but because users cannot accurately predict which part of the content is more exciting, users often skip the content they are interested in because of setting too fast fast forward speed. Part of the content, or because the setting is too slow, it cannot skip the part it is not interested in in the shortest time. ...

[0003] However, today's fast forward and rewind functions require users to set the speed of fast forward and rewind, but because users cannot accurately predict which part of the content is more exciting, users often skip the content they are interested in because of setting too fast fast forward speed. Part of the content, or because the setting is too slow, it cannot skip the part that it is not interested in in the shortest time

This will eventually lead to the inability of users to quickly and accurately locate the content of interest in the video, wasting a lot of time for users and reducing user experience
