Step S102: the television video in the ad break and each advertisement video sample are compared, and with the unmatched television video fragment of each advertisement video sample in remove to repeat video segment, from remove the unmatched television video fragment that repeats behind the video segment, determine the targeted advertisements video.
The below is specifically described above-mentioned steps.
The advertisement video sample refers to the video of single advertisement, and the advertisement video Sample Storehouse comprises the database of a plurality of advertisement videos exactly.Advertisement video sample in the advertisement video Sample Storehouse at first can obtain by collecting existing advertisement video, and secondly, the targeted advertisements video of finding from method of the present invention finally also can join in the advertisement video Sample Storehouse as the advertisement video sample.
Utilize each the advertisement video sample in the advertisement video Sample Storehouse to determine the ad break of television video in broadcast, can adopt following dual mode to carry out.
Execution mode one:
Please refer to Fig. 2, Fig. 2 is the schematic flow sheet of the embodiment one of the method for definite ad break.As shown in Figure 2, the method for determining ad break comprises:
Step S1011: in television video, gather the television video sample.In the present embodiment, can gather one day television video as the television video sample.
Step S1012: television video sample and each advertisement video sample are compared one by one, from the television video sample, determined each video segment with the advertisement video sample matches.
The method that the video comparison is adopted can be with reference to figure 3, and Fig. 3 is the schematic flow sheet of the method for video comparison.The television video sample is the source video among the figure, and the advertisement video sample is the target video among the figure.After source video and target video decoded, just can according to the method shown in Fig. 3, both be compared.
As can be seen from Figure 3, when source video and target video are compared, be actually the first frame of getting first target video, compare with each frame of source video, if not in the comparison, then getting the next frame of target video and each frame of source video compares, until find in the video of source with target video in the frame that can compare, at this moment, record the position of this frame in the video of source, the recirculation execution is got the next frame of getting in next frame and the target video and is compared from the video of source, until compare unsuccessfully, record the successful position of frame in the video of source of last comparison, at this moment, video segment between the position of the frame of two records of source video is the match video fragment.In seeking source video and target video, during first same number of frames, also can get first the first frame of source video, compare with each frame of target video, if on not comparing, do not get again the next frame of source video and each frame of target video and compare, by that analogy.If there is not a frame can compare successfully in source video and the target video, illustrate that then source video and this target video compare failure, the match video fragment of this target video not in the video of source.
Each advertisement video sample is carried out above-mentioned comparison process as target video respectively, just can find each match video fragment in the television video sample.
Please continue with reference to figure 2.
Step S1013: each match video fragment is arranged according to the time sequencing in the television video sample, therefrom determine continuous videos fragment collection and independent vide fragment.
As a rule, the advertisement of in television video, playing be have necessarily successional, these advertisements all are to concentrate to play within a period of time, interlude is shorter between each advertisement, utilize this characteristics, can find out continuous videos fragment collection, this continuous videos fragment collection refers to that the reproduction time interval between adjacent two match video fragments is no more than the match video set of segments of predetermined value.For example, five match video fragments are arranged, in these five match video fragments in twos the reproduction time between the adjacent match video fragment be spaced apart 5 seconds, then can be with these five match video fragments as a continuous videos fragment collection.Match video fragment in all match video fragments except continuous videos fragment collection just is referred to as the independent vide fragment.
Step S1014: time interval and independent vide fragment the time interval in television video sample of continuous videos fragment collection in the television video sample is defined as ad break.
The time interval of continuous videos fragment collection in the television video sample is the time interval between the first redundant moment to the second redundant moment, wherein the first redundant continuous videos fragment that constantly is arranged in concentrates first match video fragment before the zero hour of television video sample, and being carved into the continuous videos fragment during this first redundancy concentrates the time span of first match video fragment between the zero hour in the television video sample to be no more than the first threshold of setting, the second redundancy is arranged in the continuous videos fragment constantly and concentrates last match video fragment after the finish time of television video sample, and the continuous videos fragment concentrates last match video fragment to be no more than the Second Threshold of setting the finish time in the television video sample to the time span between this second redundant moment.In like manner, the time interval of independent vide fragment in the television video sample is that triple redundance is constantly to the time interval between the 4th redundant moment, wherein triple redundance was arranged in the independent vide fragment constantly before the zero hour of television video sample, and be carved into the 3rd threshold value that the time span of independent vide fragment between the zero hour in the television video sample is no more than setting during this triple redundance, the 4th redundant moment was arranged in the independent vide fragment after the finish time of television video sample, and the independent vide fragment is no more than the 4th threshold value of setting the finish time in the television video sample to the time span between the 4th redundant moment.
Please refer to Fig. 4, Fig. 4 is the schematic diagram of ad break.On scheming, can find out, in the television video sample, comprised continuous videos fragment collection and independent vide fragment, when determining ad break, ad break is the interval a period of time interval with comprising the independent vide fragment of a period of time that comprises continuous videos fragment collection.One section adjustable time is arranged in the ad break, embodied by the first threshold among the figure, Second Threshold, the 3rd threshold value and the 4th threshold value.It is identical that first threshold, Second Threshold, the 3rd threshold value and the 4th threshold value can be set to, and also can be set to difference.For example the continuous videos fragment collection time of living in is the 10th minute to the 20th minute, and ad break can be the 7th minute to the 23rd minute, and wherein first threshold is identical with Second Threshold, is three minutes.
Utilize each the advertisement video sample in the advertisement video Sample Storehouse to determine the ad break of television video in broadcast, can also adopt following mode to implement.Please refer to Fig. 5, Fig. 5 is the schematic flow sheet of embodiment two of determining the method for ad break.
