In another realizes, predetermined content can also be the audio or video file that user selects in advance.User can select one or more audio frequency (such as one section of music or a first song etc.) or video file (example make laughs video segment etc.) in advance, when the content of the specified channel that terminal is being play is advertisement, just chooses a file and play on foreground.Above-mentioned audio or video file can be the file stored in this locality, also can be the file found from network according to predetermined address, and can also be the file that other terminal is shared, the application be to not limiting in this respect.
Be appreciated that predetermined content can also be other content, the application is to not limiting in this respect.
With further reference to Fig. 2, it illustrates the flow process the Figure 200 whether content judging current specified channel that the application provides is an embodiment of the method for advertisement.
As shown in Figure 2, in step 201, the related data of the content of current specified channel is obtained.
In the present embodiment, related data can comprise following at least one item: image feature data; And audio characteristic data.Wherein, image feature data gets based on the feature extracting method accelerating robust features.Audio characteristic data gets based on the feature extracting method of Perception Features based on line spectrum feature.
Then, in step 202., described related data whether Satisfying Matching Conditions is judged based on the reference data stored.
In the present embodiment, reference data at least comprises the data with related data identical type.Such as, if related data comprises image feature data, then reference data at least also comprises the image feature data for reference.Therefore, reference data only can comprise the image feature data for reference, also except comprising the image feature data for reference, can further comprises the data (as audio characteristic data) of other kind for reference.
In the present embodiment, matching condition is included in the reference data existing in the reference data stored and match with above-mentioned related data.Specifically, an ad content data storehouse can be set up in advance, in database, store multiple reference data relevant to ad content.These reference datas can be added manually, and also can identify certain play content by certain advertisement recognition method is automatically add after advertisement.Be appreciated that and can also add the reference data relevant to ad content by another way in database, the application is to not limiting in this respect.
Further, the reference data matched with above-mentioned related data comprises the reference data being more than or equal to predetermined similarity threshold with the similarity of this related data.It should be noted that, when related data comprises the data (as related data comprises image feature data and audio characteristic data) of at least two kinds, can think that reference data matches with above-mentioned related data and comprise: the similarity of the data of kind corresponding at least two kinds of data that this related data comprises and reference data is all more than or equal to corresponding predetermined similarity threshold.
Then, in step 203, if Satisfying Matching Conditions, determine that foregoing is advertisement.
In the present embodiment, if there is the reference data matched with above-mentioned related data in the reference data relevant to ad content stored, then illustrate that the content corresponding with above-mentioned related data is advertisement.
Then, in step 203b, if non-Satisfying Matching Conditions, obtain the information of the information of user behavior relevant to the content of current specified channel and/or the subtitles appearances of this content.
In the present embodiment, if non-Satisfying Matching Conditions, in conjunction with the information of the subtitles appearances of the information of the user behavior relevant to the content of current specified channel and/or this content, can determine whether the content of current specified channel is advertisement further.
In the present embodiment, the information of relevant to the content of current specified channel user behavior comprises: the switching ratio switching foreground play content multiple user plays foregoing during in foreground.The information of the subtitles appearances of the content of current specified channel comprises following at least one item: the information of the size of the captions that foregoing is corresponding; And the information of the position of captions corresponding to foregoing.
Then, in step 204, judge whether the information of the information of user behavior relevant to the content of current specified channel and/or the subtitles appearances of this content meets predetermined condition.
In general, film, TV play, variety show or news etc., the change of subtitles appearances is less.Such as, the position of captions is generally positioned at the presumptive area below screen, or is positioned on the left of screen or right side edge place, and position is little by change, and the area size change shared by captions is also little.But the change of subtitles appearances is usually comparatively large in advertising programme, therefore, can using the change of subtitles appearances as judging that whether the content of broadcasting is the foundation of advertisement.
On the other hand, usual user's major part is not liked seeing advertisement, time especially advertisement is play than comparatively dense, has the user of larger proportion can carry out the switching of channel.Therefore, also as the content judging to play can be whether using the information of the user behavior relevant to the content of current specified channel another foundation of advertisement.
In the present embodiment, if the information of the user behavior relevant to the content of current specified channel comprises the switching ratio switching foreground play content multiple user plays foregoing during in foreground.And the information of the subtitles appearances of the content of current specified channel comprises following at least one item: the information of the size of the captions that foregoing is corresponding; And the information of the position of captions corresponding to foregoing.Then predetermined condition comprises: within a predetermined period of time, and the switching ratio switching foreground play content multiple user plays the content of specified channel during in foreground is more than or equal to predetermined switching rate threshold; And/or within a predetermined period of time, the change of subtitles appearances is more than or equal to predetermined changing features threshold value.
Be appreciated that, when only judging whether the information of the user behavior relevant to the content of current specified channel meets predetermined condition, predetermined condition comprises within a predetermined period of time, and the switching ratio switching foreground play content multiple user plays the content of specified channel during in foreground is more than or equal to predetermined switching rate threshold.When only judging whether the information of the subtitles appearances of the content of current specified channel meets predetermined condition, predetermined condition comprises within a predetermined period of time, and the change of subtitles appearances is more than or equal to predetermined changing features threshold value.
And when judging whether the information of the information of user behavior relevant to the content of current specified channel and the subtitles appearances of this content meets predetermined condition, predetermined condition only can comprise predetermined condition and comprise within a predetermined period of time, and the switching ratio switching foreground play content multiple user plays the content of specified channel during in foreground is more than or equal to predetermined switching rate threshold.Predetermined condition also can only comprise within a predetermined period of time, and the change of subtitles appearances is more than or equal to predetermined changing features threshold value.Predetermined condition can also comprise within a predetermined period of time, and the switching ratio switching foreground play content multiple user plays the content of specified channel during in foreground is more than or equal to predetermined switching rate threshold; Further, within a predetermined period of time, the change of subtitles appearances is more than or equal to predetermined changing features threshold value.
It should be noted that, if subtitles appearances comprises two or more features (as subtitles appearances comprises the size of captions and the position of captions).In one implementation, as long as wherein a kind of changing features is more than or equal to the predetermined characteristic change threshold of its correspondence, just thinks and meet predetermined condition.In another implementation, all changing features to all be more than or equal to the predetermined characteristic change threshold of its correspondence, just think and meet predetermined condition.In another realizes, as long as the changing features of predetermined kind is more than or equal to the predetermined characteristic change threshold of its correspondence, just thinks and meet predetermined condition.Such as, suppose that subtitles appearances comprises 6 kinds of features, as long as wherein any 3 kinds of changing features can be set be more than or equal to the predetermined characteristic change threshold of its correspondence, just think and meet predetermined condition.
Finally, in step 205, in response to meeting above-mentioned predetermined condition, determine that the content of current specified channel is advertisement.
In the present embodiment, if the information of the information of the user behavior relevant to the content of current specified channel and/or the subtitles appearances of this content meets predetermined condition, then determine that the content of current specified channel is advertisement.
In some Alternate embodiments, information at least partly based on the information of the user behavior relevant to the content of current specified channel and/or the subtitles appearances of this content judges whether this content is advertisement, also comprise in response to meeting above-mentioned predetermined condition, the related data of the content of current specified channel is stored as reference data.
In the present embodiment, if there is not the reference data matched with above-mentioned related data in the reference data relevant to ad content stored, may can not illustrate that the content corresponding with above-mentioned related data is not advertisement, this content is also likely the new ad content just released.Therefore, can also judge whether foregoing is advertisement by another way.If judge that foregoing is advertisement by another way, so illustrate that foregoing may be the new ad content just released, and is not stored as the reference data (as being not added in ad content data storehouse) relevant to ad content.Now, foregoing can be stored as the reference data (as add in ad content data storehouse) relevant to ad content.
It should be noted that, the reference data relevant to ad content can be stored on local terminal, also can be stored on the webserver, and the position aspect of the application to reference data storage does not limit.
With further reference to Fig. 3, it illustrates the flow process 300 of an embodiment of the method for the information of acquisition that the application the provides user behavior relevant to the content of current specified channel.
As shown in Figure 3, in step 301, the user that acquisition cloud platform collects switches the relevant information of foreground play content.
