Embodiment of the present invention technique scheme has following beneficial effect: because adopt described multimedia video data processing method to comprise: obtain pending video file; Utilize the property data base and the described video file that gather in advance formation to compare, the partial video content in the described video file that after comparison, the match is successful is identified; Partial video content in the described video file identifying is carried out to cutting operation, with the technological means splitting from described video file, so reached following technique effect: 1) the meticulous content segmentation operation of automatic batch, efficiency is high, and speed is fast; 2) by artificial and system, automatically processed and combine, accuracy rate and efficiency are laid equal stress on; 3) because the teaser or tail replacement frequency of program is low, the frequency that advertisement repeats is high, therefore can reduce in a large number manually-operated workload, no longer needs more personnel and equipment; 4) increase along with program amount only need increase treatment facility, can tackle the quick increase of following contents production scale.
Below in conjunction with application example, embodiment of the present invention technique scheme is elaborated:
The feature that application example of the present invention utilizes particular video frequency content to repeat over a period to come, by collecting the feature of these video contents, when occurring again, video carries out cutting operation, then can splice or the operation such as replacement (replacement refers to original video segment is replaced to local ready video segment, or the video content of identification is deleted).Therefore by application example of the present invention, can reach following object:
What application example of the present invention proposed is that a set of video identification technology that utilizes is realized the system that video content is carried out to auto Segmentation and replacement.This system comprises several parts below:
1) video file gets ready and collection apparatus;
2) automatic batch of video file is processed.
As shown in Figure 5, for application example multimedia video data of the present invention is processed schematic diagram:
Wherein, 1) getting ready with collection apparatus of pending video file completes a few step operations below:
A, reads and this video file of preliminary treatment.So-called preliminary treatment is before utilizing, to gather the property data base and the video content that form to compare, and the start frame of the content that can identify and end frame is recorded, and carried out mark in video window.
B, operating personnel are looked into and are seen if there is new ad content or meaningful needs are cut apart by fast forwarding and fast rewinding in broadcast window.If had, find its start frame and end frame to get operation ready.Until whole section of content check all got ready.
C, the ad content of coupling is not increased in property data base automatically through getting ready after operation is submitted to.
D, in navigation process, every content of successfully being mated in preprocessing process, identifies with visible marking.
E, the Processing tasks of getting ready finally generating is submitted to the system that automatic batch processes and processes.
2) automatic batch of video file is processed and need to be completed some contents below:
A, accepts from the submission task of getting work station ready.
B, analysis task file, extracts video file to be processed, according to the starting and ending point of describing in file, cuts apart and splices, and forms new video file, and leaves the position of appointment in.
C, collects processing progress and the result of each task and reports processing workstation.
Wherein, the collection of feature: as shown in Figure 6, be the collection schematic diagram of application example feature of the present invention, such as can be chooses some frames in the successive frame sequence of video, as 1,3,5,7 odd-numbered frame or whole successive frame etc.In each frame, choose some points, for example, by picture 16 deciles, select the pixel of bisector infall as characteristic point.Each point records its colourity and brightness value, or one of them.The value of above information point enters the acquisition order of characteristic collector according to frame, and is recorded in the middle of stored data base, i.e. characteristic sequence.In property data base, preserve some characteristic sequences that gather by above method.
Wherein, the comparison of feature: as shown in Figure 7, comparison schematic diagram for application example feature of the present invention, for a continuous sample sequence, enter after comparison model, comparative device can take out each characteristic fragment in property data base with the sample fragment that enters window and compare, and records its difference.Sample sequence is every movement one frame in comparison window, for each characteristic fragment, can generate a difference.Can obtain in this way one for the sequence of differences of each feature.As shown in Figure 7: difference list A1, A2, A3......; B1, B2, B3......; C1, C2, C3......; D1, D2, D3......; It is exactly the comparison difference row sequence for characteristic fragment A and characteristic fragment B.Obviously by analyzing the distribution in time of these change sequences, application example of the present invention can be found, in sample sequence, start to enter while comparing window with the fragment of characteristic matching, the value of above-mentioned sequence of differences starts to reduce, when this difference is reduced to zero or while approaching a threshold values, application example of the present invention can judge that fragment in sample and this characteristic matching are successfully.When the fragment of coupling starts to shift out comparison during window, difference starts to increase, and application example of the present invention increases to and is greater than zero or judge that coupling finishes while being greater than a certain threshold values according to difference.
By above-mentioned method, application example of the present invention can be found out the start-stop frame number of the successful fragment of characteristic matching in the middle of sample video sequence and in property data base automatically, and these frames are marked in operation interface, frame number and corresponding temporal information are recorded simultaneously, in file for the production of batch process task, in order to follow-up cutting apart and replacement operation for video.
The beneficial effect that application example technical scheme of the present invention is brought: compare with current pure manual mode, the method that adopts application example of the present invention to describe can improve the efficiency of contents production greatly.Take HNTV as example, and the clutter of every day is 290 left and right.Suppose that a skilled staff 8 hours can be by being marked one by one of the advertisement in the content of 24 hours, and accurate.If adopt the method for application example of the present invention, suppose that every day, newly-increased number of ads was that the actual month newly-increased advertisement of 10%(is in 10% left and right), this staff only needs to process 29 advertisements for 8 hours so, and what other were all is all completed automatically by system, and guarantees accurate.This staff can complete the contents processing of 10 channels in 8 hours, and efficiency has increased by 10 times.Compare with manual operations, automation is processed and to be guaranteed that collection apparatus is accurately in situation, and the accuracy rate of automatically processing is 100%, and the multiple review mechanism without follow-up, can use manpower and material resources sparingly and the time.The scheme providing by application example of the present invention, can realize once gathering long-term applicablely, allows staff's operation repeat no longer all day dry as dust, can raise the efficiency minimizing error.The described scheme of application example of the present invention only need increase a small amount of personnel and work station when business occurs that magnitude increases, and the mode of craft cannot be tackled increasing considerably of processing tasks in the past.
