s1, numbering the advertisement videos, and generating one or more verification feature codes of the advertisement videos according to the obtained numbers of the advertisement videos, where the verification feature codes are used to confirm the complete advertisement videos, for example, one verification feature code may be inserted at the beginning and the end of an advertisement video, and when the two verification feature codes are obtained, it is proved that the advertisement has been played and ended, and of course, when necessary, one verification feature code may be inserted only at the beginning or the end of an advertisement video;
s2, forming a verification feature data set by the verification feature codes;
s3, converting the verification feature data set into a digital audio sequence with identifiability, and compiling the digital audio sequence by adopting audio frequencies which cannot be directly identified by human ears or are not identified by the human ears;
s4, segmenting the digital audio sequence to generate one or more digital audio sequence segments;
s5, adding one or more characteristic audios in the advertisement video every other fixed time slot, wherein the quantity of the characteristic audios corresponds to the quantity of the digital audio sequence fragments;
s6, adding a digital audio sequence segment after each characteristic audio.
It should be noted that the processing sequence is not exclusive, and the skilled person can adjust the sequence according to the operation convenience principle, for example, step S5 can be performed in parallel with step S4, or step S5 is performed before step S4.
For simplicity, the numbers used in this embodiment are simplified numbers, and in practice, in order to ensure the unique correspondence of the codes, more complex numbers are used, as follows. The example is explained by taking two advertisement videos as an example, the two advertisement videos are numbered as 1 and 2, a verification feature code 1A and 1B is respectively inserted at the head and the tail of the advertisement video with the number 1, a verification feature code 2A and 2B is respectively inserted at the head and the tail of the advertisement video with the number 2, when the number 1A is acquired, the advertisement video with the number 1 is indicated to start playing until the number 1B is acquired, the advertisement video with the number 1 is indicated to finish playing, and the same is true for the advertisement video with the number 2, of course, one verification code 1A and one verification code 2A can be inserted only when the advertisement videos with the numbers 1 and 2 start or finish, and the requirement is only satisfied when the advertisement videos with the numbers 1 and 2 start and finish can be identified. In this embodiment, taking an example of inserting a verification feature code at the beginning and end of an advertisement video, the advertisement video with number 1 has a verification feature data set 1A1B, the advertisement video with number 2 also has a verification feature data set 2A2B, the two verification feature data sets 1A1B and 2A2B are converted into digital audio sequences with identifiability and not directly recognizable or recognizable by human ears, such as audio frequencies less than 20Hz or greater than 20000Hz, and then the digital audio sequences are sliced to generate one or more digital audio sequence segments, such as 1A1B and 2A2B respectively generate two digital audio sequence segments, 1A1B is sliced into two digital audio sequence segments 1a and 1b, 2A2B is sliced into two digital audio sequence segments 2a and 2b, and at the same time, a feature audio is added to the advertisement video at fixed time slots, in this embodiment, adding two characteristic audios to the advertisement video, for example, adding two characteristic audios to the advertisement video with number 1, namely alpha 1 and alpha 2, adding a digital audio sequence segment 1a after alpha 1, adding a digital audio sequence segment 1b after alpha 2, adding two characteristic audios to the advertisement video with number 2, namely beta 1 and beta 2, adding a digital audio sequence segment 2a after beta 1, and adding a digital audio sequence segment 2b after beta 2, thereby completing the processing of the advertisement video.
As shown in fig. 2, an embodiment of the present invention further provides an advertisement video identification method, including:
s1, acquiring audio signals of the advertisement videos in the advertisement video playing process, and identifying characteristic audio in the audio signals;
s2, acquiring a digital audio sequence segment attached to the characteristic audio according to the characteristic audio;
s3, merging the acquired digital audio sequence fragments to obtain a digital audio sequence;
s4, converting the digital audio sequence into a verification feature data set;
s5, calculating the number of the advertisement video according to the verification feature data set, and comparing the verification feature data set with the original verification feature data set of the advertisement video with the corresponding number;
and S6, judging that the advertisement video is played wrongly when the comparison result is not consistent, and judging that the advertisement video is played successfully when the comparison result is consistent.
This example will be described with reference to the foregoing embodiments. In the process of playing the advertisement video, the audio signal of the advertisement video is collected by a sound pickup tool such as a sound pickup device, the audio signal is transmitted to an identification processing center, the characteristic audio in the audio signal is identified, for example, if α 1 and α 2 are identified from the audio signal, the digital audio sequence segments 1a and 1b attached after the characteristic audio α 1 and α 2 can be obtained, the digital audio sequence segments 1a and 1b are combined to obtain a digital audio sequence, the digital audio sequence is reversely converted into an authentication characteristic data set 1A1B, the authentication characteristic data set 1A1B shows that the corresponding advertisement video is numbered 1, the original authentication characteristic data set of the advertisement video numbered 1 is found, the obtained authentication characteristic data set is compared with the original authentication characteristic data set, in this embodiment, the obtained authentication characteristic data set is 1A1B, the original authentication characteristic data set of the advertisement video is also 1A1B, if the two results are consistent, judging that the advertisement video is completely played; if only alpha 1 or alpha 2 is identified from the audio signal, only the digital audio sequence segment 1A or 1B which is attached to the characteristic audio alpha 1 or alpha 2 and only the digital audio sequence corresponding to 1A or 1B are obtained, the digital audio sequence is reversely converted into the verification characteristic data set, only 1A or 1B, whether 1A or 1B, the number of the corresponding advertisement video is 1, the original verification characteristic data set of the advertisement video with the number of 1 is found, the obtained verification characteristic data set is compared with the original verification characteristic data set, under the normal condition, the original verification feature data set should be 1A1B, while the resulting verification feature data set only retains a portion 1A or 1B thereof, and judging that the advertisement video is not completely played, wherein the obtained verification characteristic data set is inconsistent with the comparison result of the original verification characteristic data set. Similarly, if β 1 and β 2 or any one of β 1 and β 2 is identified from the audio signal, the playing integrity of the advertisement video with number 2 can be identified according to the aforementioned identification method, and will not be repeated here. Thereby completing the identification of the advertisement video.
