Embodiment one

As shown in Figure 1, be the crucial play time defining method flow chart that the embodiment of the present invention one proposes, its concrete handling process is as follows, comprising:

Step 11, when judging each displaying video, user performs in the setting-up time length after skip operation for described video, and whether described user again performs skip operation for described video or exit play operation.

Wherein, user comprises skip operation for the operation that video performs and exits play operation, skip operation comprises to be clicked fast forward button operation, the operation of click fast backward button, the progress bar operation of dragging video and clicks the direct skip operation of video progress bar, exits the operation that play operation comprises closedown play operation and directly jumps to other videos from this video.

Step 12, if judged result is no, then obtains play time after operation corresponding to this skip operation.

Step 13, according to play time after each operation obtained, determines the crucial play time of described video.

In the playing process of video, if the user of viewing video performs skip operation for this video, and watch this video continuously in the follow-up long period, skip operation do not performed again to this video or exit play operation, so can think that user is interested for the content after redirect.Therefore the embodiment of the present invention one proposes, when determining the crucial play time of video, for each skip operation that user during each this video of broadcasting performs, judge in the setting-up time length after performing this skip operation respectively, whether user again performs skip operation for this video or exits play operation, if judged result is no, then think that user performs in the long period after this skip operation, have viewed this video continuously, therefore obtain play time after operation corresponding to this skip operation, namely user watches the sart point in time of video continuously.

If in a playing process of video, user performs repeatedly skip operation, then perform the judgement flow process of step 11 respectively for each skip operation.

In the manner described above, can get play time after multiple operation, the crucial play time determined according to play time after these operations just can reflect each user more interested content when this video of viewing.

Wherein, the implementation of step 11 will be introduced in detail in the embodiment of the present invention two, and the implementation of step 13 will be introduced in detail in the embodiment of the present invention three.

Embodiment two

The embodiment of the present invention two proposes, and all records corresponding broadcasting daily record during each displaying video, plays daily record and can be, but not limited to comprise following content:

Session (Session) mark (Identity, ID) this time during displaying video;

The time of implementation point of the operation correspondence that user performs for video, such as, user watches certain video from 9:00, has dragged video progress bar when 9:05, then user operates corresponding time of implementation point for the dragging video progress bar that this video performs is 9:05;

Play time before the operation of the operation correspondence that user performs for video, such as, user watches the video that certain duration is 40 minutes, when being played to the 6th minute of this video, user has dragged video progress bar, then before the operation that the dragging video progress bar operation that performs for this video of user is corresponding, play time is the 6th minute;

The type identification of the operation that user performs for video;

Play time after the operation of the operation correspondence that user performs for video, such as, user watches the video that certain duration is 40 minutes, when being played to the 6th minute of this video, user has dragged video progress bar, be dragged to the 20th minute of this video, then after the operation that the dragging video progress bar operation that performs for this video of user is corresponding, play time is the 20th minute.

Above-mentioned every content is regarded respectively as the attribute playing daily record, table 1 describes attribute type and the attribute description of each attribute.

Table 1:

If in primary video playing process, user performs multi-pass operation for this video, then in the broadcasting daily record that this playing process is corresponding, the relevant information (comprising time of implementation point, the front play time of operation, the type identification of operation, the rear play time of operation) of each operation performed by journal user.

When determining the crucial play time of video, first the broadcasting daily record of all broadcasting daily records or the stipulated time section interior (in such as month or in a week) of this video recorded is obtained, thus when being play this video at every turn, user is for play time after play time, operation before the action type of the operation performed by this video and time of implementation point corresponding to operation, operation, then according to the above-mentioned information obtained, judge user perform skip operation at every turn after setting-up time length in, whether again perform skip operation or exit play operation.

The embodiment of the present invention two proposes, above-mentioned judgement can be carried out by the time of implementation point corresponding according to operation, also can carry out above-mentioned judgement according to play time after play time before the operation of operation correspondence and operation, below these two kinds of modes are introduced respectively.

First kind of way, the time of implementation point corresponding according to operation, judge user perform skip operation at every turn after setting-up time length in, whether again perform skip operation or exit play operation.

When judging each displaying video, the skip operation next time that the time of implementation point of the skip operation that user performs for this video and user perform for this video or exit play operation time of implementation point between time span whether be greater than the 3rd duration threshold value of setting, if the determination result is YES, then confirm in the setting-up time length after performing this skip operation, user does not again perform skip operation for this video or exits play operation, otherwise, confirm in the setting-up time length after performing this skip operation, user again performs skip operation for this video or exits play operation.

If in the process of displaying video, after user performs certain skip operation for video, skip operation do not performed again to this video or exit play operation, namely there is not skip operation or exit play operation next time, then can directly confirm in the setting-up time length after performing this skip operation, user does not again perform skip operation for this video or exits play operation.

As shown in Figure 2, be the time of implementation point corresponding according to operation, judge whether user again performs skip operation or exit the idiographic flow schematic diagram of play operation, and processing procedure is as follows:

Step 21, order reads time of implementation point and the rear play time of operation of each operation correspondence recorded in broadcasting daily record;

Step 22, after the operation that determining step 21 reads, whether the value of play time is empty, if the determination result is YES, then show that this is operating as and exit play operation, therefore go to step 210, if judged result is no, then show that this is operating as skip operation, therefore goes to step 23;

Step 23, judges whether record time of implementation point corresponding to next operation in this broadcasting daily record, if the determination result is YES, then go to step 24, if judged result is no, then go to step 26;

Step 24, reads the time of implementation point that the next operation that records in this broadcasting daily record is corresponding;

Step 25, whether the time span between the time of implementation point that determining step 21 reads and the time of implementation point that step 24 reads is greater than the 3rd duration threshold value of setting, if the determination result is YES, then goes to step 26, if judged result is no, then goes to step 28;

Step 26, confirms in the setting-up time length after performing this skip operation, and user does not again perform skip operation for this video or exits play operation;

Step 27, play time after the operation that recording step 21 reads, goes to step 29;

Step 28, confirms that in the setting-up time length after performing this skip operation, user again performs skip operation for this video or exits play operation;

Step 29, judges the time of implementation point and the rear play time of operation that whether record next operation in this broadcasting daily record, if the determination result is YES, then goes to step 21, if judged result is no, then go to step 210;

Step 210, terminates the judgement flow process of this broadcasting daily record.

All broadcasting daily records corresponding to video are traveled through according to step 21 ~ step 210.

The second way, according to play time after play time before the operation that operation is corresponding and operation, judge user perform skip operation at every turn after setting-up time length in, whether again perform skip operation or exit play operation.

When judging each displaying video, whether the skip operation next time that after the operation that the skip operation that user performs for this video is corresponding, play time and user perform for this video or the time span before exiting operation corresponding to play operation between play time are greater than the 4th duration threshold value of setting, if the determination result is YES, then confirm in the setting-up time length after performing this skip operation, user does not again perform skip operation for this video or exits play operation, otherwise, confirm in the setting-up time length after performing this skip operation, user again performs skip operation for this video or exits play operation.

As shown in Figure 3, for according to play time after play time before operation corresponding to operation and operation, judge whether user again performs skip operation or exit the idiographic flow schematic diagram of play operation, and processing procedure is as follows:

Step 31, play time after the operation that each operation of recording in order reading broadcasting daily record is corresponding;

Step 32, after the operation that determining step 31 reads, whether the value of play time is empty, if the determination result is YES, then show that this is operating as and exit play operation, therefore go to step 310, if judged result is no, then show that this is operating as skip operation, therefore goes to step 33;

Step 33, judges whether to record in this broadcasting daily record play time before operation corresponding to next operation, if the determination result is YES, then goes to step 34, if judged result is no, then go to step 36;

Step 34, reads play time before operation corresponding to the next operation that records in this broadcasting daily record;

Step 35, whether the time span before the operation that after the operation that determining step 31 reads, play time and step 34 read between play time is greater than the 4th duration threshold value of setting, if the determination result is YES, then goes to step 36, if judged result is no, then go to step 38;

Step 36, confirms in the setting-up time length after performing this skip operation, and user does not again perform skip operation for this video or exits play operation;

Step 37, play time after the operation that recording step 31 reads, goes to step 39;

Step 38, confirms that in the setting-up time length after performing this skip operation, user again performs skip operation for this video or exits play operation;

Step 39, judges whether to record in this broadcasting daily record play time after operation corresponding to next operation, if the determination result is YES, then goes to step 31, if judged result is no, then go to step 310;

Step 310, terminates the judgement flow process of this broadcasting daily record.

All broadcasting daily records corresponding to video are traveled through according to step 31 ~ step 310.

In the first judgment mode above-mentioned and the second judgment mode, the 3rd duration threshold value can be identical with the 4th duration threshold value, also can be different.

Due to different users watch same video time, interested content also may be different, therefore the embodiment of the present invention two proposes, for dissimilar user, determine the crucial play time of each video respectively, then when user asks displaying video, the crucial play time corresponding with user type can be marked on the video progress bar of this video, user just can navigate to oneself interested content more fast, achieve as dissimilar user provides the object of the service of video preview targetedly, concrete:

Play in daily record except the every content shown in record sheet 1, can also record the user type of the user of this video of viewing, wherein, user type can divide according to the age of user, and the kind of the video also can watched according to user divides.When determining the crucial play time of video, can for each user type, obtain the broadcasting daily record that this user type is corresponding respectively, then the crucial play time of this video is determined in corresponding according to this user type broadcasting daily record, just can obtain the crucial play time of this video corresponding to each user type thus.

Embodiment three

The embodiment of the present invention three proposes, and to get after each operation of video after play time, directly play time after each operation got can be confirmed as the crucial play time of video according to step 11 and step 12.

In addition, in order to improve the accuracy of the crucial play time determined, the embodiment of the present invention three proposes, also can to get after each operation of video after play time according to step 11 and step 12, Preliminary screening is carried out to play time after each operation got, filter out interest play time, then determine crucial play time according to each interest play time filtered out.

When play time carries out Preliminary screening after to each operation got, first the interest-degree of play time after each operation obtained is determined, then filter out interest-degree and be greater than play time after the operation of the first interest-degree threshold value of setting, play time after the operation filtered out is confirmed as the interest play time of video, again according to each interest play time of this video, determine the crucial play time of this video.

By above-mentioned steps, the interest-degree distribution schematic diagram of each interest play time can be obtained, as shown in Figure 4.

After determining each operation during the interest-degree of play time, for play time after the arbitrary operation obtained, perform following operation respectively:

First the number of times that after determining this operation, play time occurs in play time after each operation obtained and the broadcasting time of this video, then the number of times occurred in play time after each operation obtained according to play time after this operation and the broadcasting time of this video, determine the interest-degree of play time after this operation.

Wherein, can be, but not limited to the interest-degree by play time t after following manner determination operation:

Δ_{t} = \frac{I_{t}}{N}

Wherein, Δ _tfor operating the interest-degree of rear play time t;

N is the broadcasting time of described video.

Because the interest-degree operating rear play time determines according to the number of times of play time appearance after this operation and the broadcasting time of video, therefore after operation, the interest-degree of play time reflects the frequency that each user watches video continuously after video is jumped to this time point, the interest level of each user to the content after this time point in video can be characterized, play time after operation larger for interest-degree is screened as interest play time, can effectively improve the accuracy determining crucial play time.

The number of times that after introducing how determination operation below, play time occurs in play time after each operation obtained:

When getting play time after certain operation for the first time, record play time after this operation, and the number of times that play time after this operation occurs is counted 1, again get play time after this operation if follow-up, then number of times play time after this operation occurred is accumulative adds 1.In the manner described above, just can real-time statistics go out each operation after the number of times that occurs in play time after each operation obtained of play time.

Embodiment four

The embodiment of the present invention four proposes, and go out each interest play time of video in the embodiment of the present invention three Preliminary screening after, each interest play time that can directly Preliminary screening be gone out confirms as the crucial play time of video.

In addition, in order to improve the accuracy of the crucial play time determined further, the embodiment of the present invention four proposes, also can after Preliminary screening goes out each interest play time of video, carry out programmed screening to each interest play time that Preliminary screening goes out, each interest play time then gone out according to programmed screening determines crucial play time.

When each interest play time gone out Preliminary screening carries out programmed screening, first according to each interest play time of this video, determine that the interest of this video plays the period, then according to each interest play time that the interest broadcasting period comprises, determine the crucial play time of this video.

Wherein, the interest time span play in the period between any two adjacent interest play time is not more than the first duration threshold value of setting, and interest is play in the period and at least comprised three interest play time.

When determining that the interest of video plays the period, first cluster analysis is carried out to each interest play time of this video, obtain several interest and play moment group, wherein, the interest time span play in moment group between any two adjacent interest play time is not more than the first duration threshold value of setting, and at least comprise three interest play time in interest broadcasting moment group, then play moment group according to these points of interest and can infer that several interest plays the period.

Such as, it is G={t1, t2 that certain interest plays moment group ..., tn}, wherein t1<t2< ... <tn, so this interest plays the interest broadcasting period of moment group correspondence is [t1, tn].

The time interval of playing due to interest between each interest play time in the period is shorter, therefore can think that the content that most of user plays the period to interest is interested, play the crucial play time of each interest play time determination video that the period comprises according to interest, can effectively improve the accuracy determining crucial play time.

Embodiment five

The embodiment of the present invention five proposes, and goes out after interest plays each interest play time of comprising of period at the embodiment of the present invention four programmed screening, directly interest can be play the crucial play time that each interest play time that the period comprises confirms as video.

To interest play each interest play time of comprising of period carry out third time screen time, when first obtaining each displaying video, play time before the operation that the skip operation that user performs for this video is corresponding, then the non-interest-degree of play time before each operation obtained is determined, non-interest-degree is greater than play time before the operation of the non-interest-degree threshold value of setting, confirm as the non-interest play time of this video, according to each non-interest play time of this video, determine that the non-interest of this video plays the period, then play deletion and non-interest the period from interest and play the common factor period of period, again according to each interest play time that the interest broadcasting period after the deletion common factor period comprises, determine the crucial play time of this video.

Wherein, the non-interest time span play in the period between any two adjacent non-interest play time is not more than the second duration threshold value of setting, and non-interest is play in the period and at least comprised three non-interest play time.

If a large number of users all performs skip operation to during certain time point for this video in video playback, then can think that the content of each user to this time point is lost interest in, this time point is non-interest play time, the time interval that non-interest is play between each non-interest play time in the period is shorter, therefore can think that most of user loses interest in the content that non-interest plays the period, play deletion and non-interest the period from interest and play the common factor period of period, the crucial play time of each interest play time determination video that the period comprises is play again according to interest, can effectively improve the accuracy determining crucial play time.

Before determining each operation during the non-interest-degree of play time, for play time before the arbitrary operation obtained, perform following operation respectively:

First the number of times that before determining this operation, play time occurs in play time before each operation obtained and the broadcasting time of this video, then the number of times occurred in play time before each operation obtained according to play time before this operation and the broadcasting time of this video, determine the non-interest-degree of play time before this operation.

Wherein, can be, but not limited to the non-interest-degree by play time t before following manner determination operation:

Δ_{t}^{'} = \frac{I_{t}^{'}}{N}

Wherein, Δ _t' for operating the non-interest-degree of front play time t;

N is the broadcasting time of described video.

Because the non-interest-degree operating front play time determines according to the number of times of play time appearance before this operation and the broadcasting time of video, therefore before operation, the non-interest-degree of play time reflects each user and performs the frequency of skip operation at this time point to video, the interest level of each user to the content of this time point in video can be characterized, play time before operation larger for non-interest-degree is screened as non-interest play time, can effectively improve the accuracy determining crucial play time.

The number of times that before introducing how determination operation below, play time occurs in play time before each operation obtained:

When getting play time before certain operation for the first time, record play time before this operation, and the number of times that play time before this operation occurs is counted 1, again get play time before this operation if follow-up, then number of times play time before this operation occurred is accumulative adds 1.In the manner described above, just can real-time statistics go out each operation before the number of times that occurs in play time before each operation obtained of play time.

When determining that the non-interest of video plays the period, first cluster analysis is carried out to each non-interest play time of this video, obtain several non-interest and play moment group, wherein, the non-interest time span play in moment group between any two adjacent non-interest play time is not more than the second duration threshold value of setting, and at least comprise three non-interest play time in non-interest broadcasting moment group, then play moment groups according to these non-points of interest and can infer that several non-interest play the period.

Such as, it is NG={t1, t2 that certain non-interest plays moment group ..., tn}, wherein t1<t2< ... <tn, so this non-interest plays the non-interest broadcasting period of moment group correspondence is [t1, tn].
