Embodiment 1

[0049] In this embodiment, a method for highlighting clips based on the playback volume of video segments will be provided, which is applied between the server and the client, and combined with figure 1 , the method includes the following steps:

[0050] Step 101: different clients collect user operation information during video playback, and feed back the user operation information to the server;

[0051] The client in the present invention includes: a mobile terminal and / or a non-mobile terminal, and a non-mobile terminal refers to a PC terminal or other desktop terminals. Here, the client is not specifically limited, and it depends on the actual situation.

[0052]In this step, the different clients collect user operation information during video playback, and feed back the user operation information to the server. The method collects user operation information for a certain video during video playback, and feeds back the user operation information to the server. The stat...

Embodiment 2

[0063] On the basis of Embodiment 1, an application embodiment of a method for highlighting clips based on the playback volume of video segments will be provided. In this embodiment, the clips in the first episode of the video "Let's Get Married" are extracted. The result Such as figure 2 As shown in , where the abscissa is the video duration in seconds, the ordinate is the number of events such as dragging, fast forwarding, and rewinding performed by the user in the video (or the segment value per second), and the curve represents dragging, For the distribution of event operations such as fast forward and rewind (or the distribution of segment values ​​per second), it can be seen from the figure that a total of five highlights are extracted. The method in this embodiment is as follows:

[0064] Step 101: different clients collect user operation information during video playback, and feed back the user operation information to the server;

[0065] In this step, the different...

Abstract

The invention discloses a video segment playback amount-based method for labeling highlights. The method comprises the following steps: obtaining actual play ratio values by a server by taking second as a time interval according to the combination of user operation information fed back by different client sides and video information; and extracting the play ratio values which are in various actual play ratio values which take second as time interval in the video and higher than or equal to the play ratio value, of extracted highlight information, preset in the server; simultaneously extending towards the former and the later time axes or extending in a single direction towards the later time axis from the time value in the time axis of the video and corresponding to a fixed point according to the fixed point in combination with a preset play time threshold value of the highlight information, wherein the fixed point is the time point of a second corresponding to the extracted actual play ratio value, and intercepting playing and extracting the corresponding highlight information when the play time threshold value is reached. The method disclosed by the invention is used for providing video clips with which a user is interested the video by taking large-data application in combination with interaction data of the user within a relatively short time after the video is on-line.

Description

technical field [0001] The present application relates to the field of video technology, and in particular, relates to a method for labeling highlight segments based on the playback volume of video segments. Background technique [0002] With the development of computers and networks, users can access more and more video data. Video data provides a large amount of information, and its content is more abundant, intuitive and vivid. [0003] In order to mine the potential value of videos, users need to be able to efficiently retrieve the desired video clips. When a user watches an online video, he often does not know what exciting content will be in the video, in order to guide the user to watch. The video site will edit the corresponding highlights shortly after the video is uploaded. Taking TV dramas as an example, the start position of the opening, ending, and highlights in the middle are generally marked. The work of determining the location of the various video conten...
