Media fast playing method, includes the following steps:
Step 1, Clustering Segmentation prestore video:
For the video prestored in server, by the similarity of color accounting, by continuous frame pictures all in video
It is clustered, video is first polymerized to n class, the video frame in this n class is similar, and the video frame between class and class is not
It is similar.According to cluster as a result, original video is divided into n video segmentation.
The mode of above-mentioned cluster can choose cluster mode commonly used in the prior art, it is preferable that can be by calculating two
The similarity of a adjacent frame image, i.e., corresponding minimum value at cumulative two image histogram same index, to realize cluster.
Step 2, Selecting Index frame, settling time axis file:
Extract the index frame of the timeline information and each video segmentation that prestore video, settling time axis file.For
N above-mentioned video segmentation extracts its first frame picture of each video segmentation as index frame, extracts the same of first frame picture
When extract the time indicator information of the picture, the index frame of above-mentioned n video segmentation and its time pointer information are corresponded to
It prestores on the time shaft of video, to form time shaft file.Therefore, time shaft file includes video full time axis and refers to
The index frame on time point is corresponded to time shaft.
Meanwhile time shaft file further includes the label field with time indicator.The label field can be null field
Or part prestored information.The label field can be character code.The time indicator of the label field can be any time
Point, including index frame corresponding time point.Preferably, a portion of the label field can be by the data of content supplier
Treatment people carries out typing, such as the Key Points title that label information can be added in instructional video.The label word
The content of section is also sky, then can carry out typing by viewer after downloading to video playing small routine client, and feed back
The cloud index file of meeting server.
Step 3 establishes cloud index file:
It extracts the timeline information for prestoring video and the label field with time indicator constitutes cloud index file, the cloud
Content offer can be also possible to by receiving the label information fed back by client user by holding the label field of index file
The label information is stored in the corresponding positions of the time shaft in the index file of cloud by the information of the preparatory typing of data processing personnel of quotient
It sets.Client user can carry out the retrieval of cloud index file by login service device to obtain for the video information
More comprehensive keyword description, to expand the information content of retrieval.It especially can be with when client's viewing video for the first time
The a large amount of description informations collected in the index file of cloud are directly based upon to quickly search and play corresponding video segmentation.
Step 4 receives client terminal playing request, by time shaft file download to client:
After server receives the playing request of client, not directly by video stream buffer to client device, but
Only by time shaft file download into client local device.The local zone time axis file includes time shaft, refers to the time
The index frame of needle and label field with time indicator.The data volume that can suitably reduce buffering is done so, money is reduced
The occupancy in source.
Step 5, client user select broadcast mode:
After by time shaft file download to client device, user can by the option on client terminal playing interface,
It chooses whether to carry out video playing by way of intelligently quickly playing.
Preferably, selection movement can quickly play virtual push button by an intelligence on click/release broadcast interface
Or it chooses whether to broadcast by way of intelligently quickly playing to carry out video realizing by way of popping up inquiry session frame
It puts.
Step 6, if user quickly plays without intelligence, sequence buffer simultaneously plays multiple video segmentation:
If client user's selection is quickly played without intelligence, sequential segment buffering, and sequence are carried out to video
It is complete to play video.During sequential full plays entire video, client user can be for the view of particular point in time
Frequency content carries out the typing of label field information, to add label to the video information on the time point, and by typing marking-up
Section content storage is into local zone time axis file.
Specifically, client user can be clicked by the time shaft on video player interface, click, double-click
Or the movements such as long-pressing carry out the label field typing at corresponding time point to activate addition label dialog box.After typing, on
It states the label field with time indicator and is stored into local zone time axis file, while being also uploaded to cloud index file.It is preferred that
Ground, the time shaft position for adding label field can be any point-in-time, or index frame corresponding time point.
Step 7, if client user selects to carry out intelligence quickly broadcasting, priority buffer broadcasting meets user query
At least one video segmentation of condition:
When client user select carry out intelligence quickly play, broadcast interface pop up inquiry session frame, user by
The keyword of the related content played is wished in input in inquiry session frame, so that the label field to local zone time axis file carries out
Retrieval.
If to the keyword retrieval of the label field of local zone time axis file have hit as a result, so extracting the life
The time indicator of the label field of middle result.The hit results are at least one.At least one life is determined by time indicator
Video segmentation where the label field of middle result, client first buffer at least one above-mentioned hit results to server request
The corresponding video segmentation of label field, and preferentially play above-mentioned video segmentation.User is obtained preferentially to need to watch
Video segmentation, improve the efficiency and speed of video playing, avoid it is unnecessary buffering and inquiry caused by delay.
Preferentially local zone time axis file is scanned for, retrieval can be made to focus first on the key of user itself definition
Word, therefore retrieval local zone time axis file can not only reduce the resource that retrieval occupies first, and since I describes to have
Certain habituation and regularity, the probability of hit can be greatly improved by retrieving customized keyword first.
If to the keyword retrieval of the label field of local zone time axis file without it is hitting as a result, not as client to
Above-mentioned information of the local zone time axis document retrieval without hit results of server feedback, and game server, to cloud index file
Label field carry out keyword retrieval.By carrying out supplement retrieval to cloud index file, the video is believed to obtain
More comprehensive keyword description is ceased, to expand the information content of retrieval.It especially can when client's viewing video for the first time
To be directly based upon a large amount of description informations collected in the index file of cloud to quickly search and play corresponding video segmentation.
If to the keyword retrieval of the label field of cloud index file without it is hitting as a result, not as mentioned by pop-up
Show client user without hit results, and multiple video-frequency bands of sequence buffer show index frame and its corresponding mark on a timeline,
Selection is manually carried out for client user to jump.This is done so that again without hit search result when also provide the user with certain base
Plinth information, facilitates user to operate as needed.
If to the keyword retrieval of the label field of cloud index file have hit as a result, so extracting the hit
As a result the time indicator of label field.The hit results are at least one.At least one hit is determined by time indicator
As a result the video segmentation where label field, client first buffer at least one above-mentioned hit results to server request
The corresponding video segmentation of label field, and preferentially play above-mentioned video segmentation.User is made preferentially to obtain what needs were watched in this way
