Problems solved by technology

[0002] In the process of watching TV dramas, users often encounter some TV dramas with complicated plots, and there are many invalid plots. Most of the existing technologies save user time by automatically skipping the beginning and the end. Plot nodes (mainly for movies) to save time for video playback methods, but none of them analyze the content of the video. 2. Technology to improve user experience

Embodiment 1

[0081] image 3 It is a flow chart of a method for fast video playback on a mobile terminal according to Embodiment 1 of the present invention, combined below image 3 To describe a method for fast video playback of a mobile terminal in an embodiment of the present invention, such as image 3 As shown, a method for fast video playback of a mobile terminal includes:

[0082] S10. Receive a video fast play instruction, the video fast play instruction includes a fast forward magnification, and the video includes several video clips;

[0083] S20. Determine the first priority of the video clip according to the subtitle of the video clip, the change value of the video picture, and the audio signal of the video clip;

[0084] S30. Perform accelerated playback of the video according to the fast-forward magnification and the first priority of the video segment.

[0085] In this embodiment, by analyzing the subtitles, audio and video change values ​​of the video, the invalid episode...

Embodiment 2

[0088] Figure 4 It is a flow chart of a method for fast video playback of a mobile terminal in this embodiment; as Figure 4 As shown, the step S20 specifically includes:

[0089] S21. Determine whether the server has the video;

[0090] S22, if so, mark the video segment without subtitles as a first-level jump into the video segment by the server side;

[0091] S23. Mark the video clips whose video picture change value is smaller than the preset change threshold among the first-level jumping video clips as the second-level jumping video clips;

[0092] S24. Mark a video clip without an audio signal or a video clip whose audio signal is background music among the secondary jump video clips as a triple jump video clip.

[0093] In this embodiment, the function of the server side is relatively powerful. When the watched video is on the server side, the change value of the video picture in a certain video segment can be detected through the server side. When the change value ...

Embodiment 3

[0095] Figure 5 It is a flow chart of a method for fast video playback of a mobile terminal in this embodiment; as Figure 5 As shown, after the step S21, it also includes:

[0096] S25. If the server does not have the video, mark the video segment without subtitles as jumping into the video segment from level 4 through the mobile terminal;

[0097] S26. Mark a video clip without an audio signal or a video clip whose audio signal is background music among the four-level jump video clips as a five-level jump video clip.

[0098] In this embodiment, when the video being viewed is not on the server side, the video can only be processed through the mobile terminal, and for some mobile terminals with low performance, the change value of the video picture in a certain video segment cannot be detected , only the subtitles and audio of the video can be detected to determine the first priority of the video segment.

[0099] As another embodiment, when the performance of the mobile ...

Abstract

The invention discloses a rapid video play method and device of a mobile terminal, and belongs to the technical field of communication. The method comprises that a rapid video play instruction which comprises the fast-forward multiplying power is received, and a video comprises multiple video segments; the fast-forward priorities of the video segments are determined according to captions of the video segments, change values of video frames and audio signals of the video segments; and the video is played in an accelerated manner according to the fast-forward multiplying power and the fast-forward priorities. Thus, the video captions, audio and the change values of the video are analyzed to intelligent skip ineffective plots of the video, the video watching time is reduced, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for fast video playback on a mobile terminal. Background technique [0002] In the process of watching TV dramas, users often encounter some TV dramas with complicated plots, and there are many invalid plots. Most of the existing technologies save user time by automatically skipping the beginning and the end. Plot node (mainly for movie) saves the time video playback method, but all does not analyze the content of video two and improve the technology of user experience. Contents of the invention [0003] The main purpose of the present invention is to propose a method and device for fast video playback on mobile terminals. By analyzing the subtitles, audio and video change values ​​of the video, the invalid plot of the video can be intelligently skipped, thereby saving video viewing time and being more beneficial. in user experience. [0004...
