The image feature data of each frame image in video to be processed；According to the similarity of the image feature data of adjacent two field pictures,
Video to be processed is divided at least two sub-videos and plays scene, and therefrom chooses a sub- video playing scene as video
Segment data.
Wherein, image feature data can be the tri- Color Histogram information of RGB in every frame image, the figure of adjacent two field pictures
As the similarity of characteristic refers to the tri- Color Histogram distance of RGB of adjacent two field pictures.
Video playing scene to be processed includes that at least two sub-videos play scene, and it is basis that each sub-video, which plays scene,
What the scene in video content determined, when video-frequency playing content lower shooting in the same scene, then belong to same height view
Frequency plays scene, when what is shot under the different scene of video-frequency playing content, then belongs to different sub-videos and plays scene.
Optionally, as shown in Fig. 2, according to the similarity of the image feature data of adjacent two field pictures, by video to be processed
It is divided at least two sub-videos and plays scene, and therefrom choose a sub- video playing scene as video segment data, comprising:
201: the similarity of the image feature data of adjacent two field pictures is determined, when similarity is less than similarity threshold, it is determined that phase

Every group of adjacent two field pictures in select previous frame image as video node；202: according to the video node, will it is described to
Processing video is cut into multiple sub-videos and plays scene；203: playing scene from multiple sub-videos and choose the longest son of play time
Video playing scene is as video segment data.
Wherein, similarity threshold is distance threshold.Then when similarity is less than similarity threshold, it can be considered that distance values are big
In distance threshold, determine that adjacent two field pictures are that different video plays scene.
For example, reading each frame image of the short-sighted frequency according to described previously, count in the short-sighted frequency in every frame image
Tri- Color Histogram information of RGB counts the tri- Color Histogram information of RGB in the short-sighted frequency in every frame image, determines adjacent two frames figure
The tri- Color Histogram distance of RGB of picture, the distance can for L2 Euclidean distance, the friendship of histogram, Hausdorff Hao Siduofu away from
From when the distance is less than distance threshold, then two consecutive frame images are to belong to the same video playing scene, when the distance is big
When distance threshold, two consecutive frame images are not belonging to the same video playing scene, at this point it is possible to be extremely by the short-sighted frequency division
Few two sub- video playing scenes, the play time of scene is played further according to each sub-video, determines the longest son of play time
Video playing scene is as the video segment data for indicating video playing scene to be processed, when at least two sub-videos play scene
When play time is identical, then according to short-sighted frequency play time sequence, select first broadcasting sub-video play scene as

Number of image frames is set, such as the play time 48s of 120 frames and short-sighted frequency, 120 frames is uniformly selected from 48s, since video is
24 frames/s, then short-sighted frequency one shares 1152 frames, every 1152/120=9.6 frame will select a frame, i.e., every 9.6/24=
0.4s will select a frame, i.e., first frame image is selected since 0.4s, be separated by 0.4s and select second i.e. 0.8s's of frame image
Frame image, and so on, until selecting enough 120 frame images.
Optionally, according to the preset maximum play time interval in any video between two frame images, from video number of segment
Multiple frame images are selected in, are specifically included: according to preset frame amount of images and preset maximum play time interval, according to broadcasting
Time sequencing is put, the frame image of preset frame amount of images is selected from video segment data, or according to preset maximum play time
Interval, according to play time sequence, selects multiple frame images from video segment data.
Wherein, which refers to chooses multiple frame images from original video, multiple frame image
The broadcasting content that the new video of composition is able to maintain original video in broadcasting content does not disconnect, any in multiple frame image at this time
The maximum time interval of two consecutive frame images.
For example, when the play time 70s of short-sighted frequency is less than 60s, which is according to described previously
120,0.5s is divided between preset maximum play time, selects first frame image 0.5s since video-frequency band, is separated by 0.5s choosing
The frame image of second i.e. 1s of frame image is selected, and so on, until selecting enough 120 frame images；Alternatively, being played according to maximum
Time interval 0.5s, the uniform design from video-frequency band select first frame image such as since 0.5s, are separated by 0.5s selection the
Two frame image, that is, 1s frame images, and so on, until the video-frequency band of 70s terminates, 140 frame images have been selected altogether.
In some instances, this method further comprises: according to two in any video playout speed and any video
Preset largest interval frame number between frame image, when determining the preset maximum broadcasting in any video between two frame images
Between be spaced；According to preset frame amount of images and the preset maximum play time interval, the time threshold is determined.
For example, according to described previously, by watching multiple videos, according to the playback progress of each video-frequency playing content, needle
For any video, the maximum frame number interval of video " play and disconnect " is not caused to be estimated, e.g., 12 frame images, then
Two are calculated in the i.e. any video of largest interval time deltaT of candidate frame image selection according to 24 frames/second broadcasting speed
Preset maximum play time interval between frame image, e.g., 0.5s, the totalframes chosen according to deltaT and fixed requirement, that is, pre-
120 frame of frame amount of images is set, above-mentioned threshold value timevalTH, e.g., 0.5s*120=60s can be calculated.
