A kind of video playing appraisal procedure provided in an embodiment of the present invention is introduced first below, as shown in Figure 1, this
A kind of video playing appraisal procedure that inventive embodiments provide includes the following steps.
S101, the grade point and target that obtain the levels of sharpness factor of played video play the numerical value of the factor.
The levels of sharpness factor is the feature assessed the clarity of played video.It is user's body based on clarity
Relatively intuitive impression in testing, and clarity is affected to user's assessment, using the levels of sharpness factor as the master for influencing QoE
Want the factor.That is, the influence of the levels of sharpness factor is paid the utmost attention in evaluation process, in the levels of sharpness factor
On the basis of consider further that the influences of other factors.
Wherein, the grade of the levels of sharpness factor is preset, and the division of grade can be customized, each grade
Indicate the readability of video.For example, clarity can be divided into 11 grades, wherein grade 0 indicates that clarity is minimum,
Grade 11 indicates clarity highest.In addition, the foundation of grade classification is also possible to customized setting, for example, can be foundation
The code rate of video divides, and can also be that the resolution ratio according to video is divided.The division of levels of sharpness is in addition to more than
Other than two kinds, it can also be divided, be not limited thereto according to other reasonable factors.
In a kind of embodiment, the grade point of the levels of sharpness factor of played video is obtained, may include walking as follows
Suddenly.
Obtain the playing duration of the code rate of played video and the video of each code rate.It wherein, can be with for played video
It is only a kind of video of code rate, can also be the video including various code rate.
When played video is only a kind of video of code rate, then duration of the played video is the video of the code rate
Duration.For example, the playing duration of played video is 3 minutes, and the played video is the video that code rate is 600, then obtains
Take played video code rate be 600, the video of the code rate when it is 3 minutes a length of.
When played video includes the video of various code rate, available this played each code rate in video,
And determine the playing duration of the video of each code rate.For example, the duration of played video is 5 minutes, wherein having 3 minutes
The code rate of video is 600, and in addition the code rate of 2 minutes videos is 500, then the available code rate arrived includes 500 and 600, and
The playing duration that can also determine the video that code rate is 500 is 2 minutes, and the playing duration for the video that code rate is 600 is 3 points
Clock.
After getting the playing duration of video of code rate and each code rate, based on acquired code rate and playing duration,
The average bit rate of played video can be calculated.In a kind of implementation, each code rate that will acquire is corresponding with the code rate
The playing duration of video carries out multiplication calculating, and code rate each in this way can correspond to obtain a product, by obtained each product
Read group total is carried out, and by obtained summed result divided by the total duration of played video, then available average bit rate.
For example, the total duration of played video is 5 minutes, wherein the code rate of 3 minutes videos is 600, in addition 2 minutes
The code rate of video is 500, then can calculate average bit rate according to the following formula:
It is 560 that average bit rate, which can be calculated, by above formula.
After calculating the average bit rate to play video, it can be determined from preset rating factor corresponding relationship
The corresponding grade point of average bit rate, the grade point as played video.
Wherein, each grade point of the levels of sharpness factor and the corresponding relationship of code rate are recorded in rating factor corresponding relationship.
In a kind of implementation, the corresponding range of code rates of each grade point, that is, be in the range of code rates in rating factor corresponding relationship
Interior code rate corresponds to the grade point.
For example, clarity is divided into 10 grades, respectively grade 0, grade 1, grade 2, grade 3, class 4, grade
5, class 6, grade 7, grade 8 and grade 9, wherein in rating factor corresponding relationship, the corresponding range of code rates of grade 0 be (0,
235), the corresponding range of code rates of grade 1 be [235,375), the corresponding range of code rates of grade 2 be [375,1050), grade 3 is corresponding
Range of code rates be [1050,1750), the corresponding range of code rates of class 4 be [1750,2350), the corresponding range of code rates of class 5
For [2350,4300), the corresponding range of code rates of class 6 be [4300,5800), the corresponding range of code rates of grade 7 be [5800,
7000), the corresponding range of code rates of grade 8 be [7000,8000), the corresponding range of code rates of grade 9 be [8000 ,+∞).Wherein,
(0,235) it indicates to be greater than 0 and the numberical range less than 235, [235,375) it indicates to be greater than or equal to 235 and the number less than 375
It is worth range, [8000 ,+∞) it indicates to be more than or equal to 8000 numberical range.So, based on the corresponding pass of above-mentioned rating factor
System, when average bit rate is 560, corresponding grade point is 2, then can determine that the grade point of played video is 2.
It may include playing the interactive factor and/or playing to experience the factor that target, which plays the factor, wherein playing the interaction factor can
With include seek behavior, rise broadcast it is time-consuming, rise and broadcast time-consuming accounting etc., wherein seek behavior refers to user in video display process
Pull the behavior of progress bar.Playing the experience factor may include Caton number, Caton duration, pause frequency, Caton duration accounting
Deng.
It is believed that including the following three types situation to the assessment of played video: the first situation, for levels of sharpness
The factor and the broadcasting interaction factor are assessed, and the levels of sharpness factor has correlation with the interaction factor is played.Second situation,
It is assessed for the levels of sharpness factor and the broadcasting experience factor, the levels of sharpness factor has related to the broadcasting experience factor
Property.The third situation for the levels of sharpness factor, plays the interaction factor and plays the experience factor and assessed, clarity etc.
The grade factor all has correlation with playing the interaction factor, play the experience factor respectively, and play the interaction factor and play experience because
Do not have correlation between son.In a third case, only to include: the levels of sharpness factor interact the factor with playing to cross feature
Cross feature, the levels of sharpness factor and play experience the factor cross feature, reduce answering for calculating to a certain extent
Miscellaneous degree.
Wherein, the levels of sharpness factor and the correlation and the levels of sharpness factor and playing body that play the interaction factor
The correlation for testing the factor may each be linear dependence.
S102 is determined acquired etc. from each grade point of the levels of sharpness factor and the corresponding relationship of valuation functions
Grade is worth corresponding valuation functions, as goal-based assessment function.
Wherein, valuation functions are using the broadcasting interaction factor and/or to play the linear function for experiencing the factor as variable, each
Valuation functions may each be preset.
Wherein, each grade point of the levels of sharpness factor and the corresponding relationship of valuation functions can be preset, every first-class
Grade is worth a corresponding valuation functions.Valuation functions corresponding for any two grade point, can be identical, can also each not phase
Together, it is not limited thereto.
In a kind of embodiment, each grade point of the levels of sharpness factor and the corresponding relationship of valuation functions can be with point
Section function representation are as follows:
H=δ (r) hr+Cr
Wherein, δ (r) indicates that the activation primitive for being directed to grade point, r indicate grade point, hrIt indicates to comment corresponding to grade point r
Estimate function, h indicates determined goal-based assessment function, CrIndicate that the constant term for being r for grade point, the constant term can be certainly
Definition setting.In a kind of implementation, constant term CrCan be according to model training come out.Wherein, different brackets value
Constant term can be identical, can also be different, be not limited thereto.
For above-mentioned piecewise function, can specifically indicate are as follows:
After getting grade point, then the activation primitive of the grade point is 1, and the activation primitive of other grade points is 0, this
When the corresponding valuation functions of the grade point be activated, by excitement valuation functions be goal-based assessment function.
For example, the grade point of the levels of sharpness factor of the played video got is 1, then δ (1) is 1, δ (0), δ
(2) etc. other activation primitives are 0, i.e., obtained goal-based assessment function are as follows: h=h1+C1。
In a kind of embodiment, preset Segment evaluation function is obtained:
Wherein, h is goal-based assessment function, hiValuation functions when for grade point being i, δ (i) is that grade point is corresponding to i
Activation primitive, when activation primitive is activated value be 1, when activation primitive is not activated value be 0.It will be acquired etc.
The activation primitive activation of grade value, obtains goal-based assessment function.
S103 is played the numerical value of the factor based on goal-based assessment function and identified target, obtains goal-based assessment function
As a result, and result is determined as to played the assessment result of video.
When goal-based assessment function is to play linear function of the interaction factor as variable, it is to play that target, which plays the factor,
The interaction factor；When goal-based assessment function is to play linear function of the experience factor as variable, it is to broadcast that target, which plays the factor,
Put the experience factor；When goal-based assessment function is to play the interaction factor and play linear function of the experience factor as variable,
It includes playing the interaction factor and playing the experience factor that target, which plays the factor,.
In the corresponding substitution goal-based assessment function of the numerical value that target is played the factor, it can obtain the goal-based assessment function
As a result, the result is the assessment result of played video.In a kind of implementation, the assessment result of played video is
QoE scoring.
In a kind of embodiment, it is to play the interaction factor that target, which plays the factor, wherein playing the interaction factor has included broadcasting consumption
When and/or rise broadcast time-consuming accounting.That is, it can only include broadcasting time-consuming or rising to broadcast time-consuming accounting that target, which plays the factor, also
It can simultaneously include broadcasting time-consuming and rising to broadcast time-consuming accounting.Wherein, it rises and broadcasts time-consuming and refer to that user is clicking video playing to user
Time needed for seeing video first frame picture rises and broadcasts time-consuming accounting and referred to the ratio for broadcasting time-consuming and video total duration.
In the case that the target broadcasting factor has been to broadcast time-consuming, obtains and broadcast time-consuming numerical value；It is when target plays the factor
It rises in the case where broadcasting time-consuming accounting, has obtained the numerical value for broadcasting time-consuming accounting；It has included broadcasting time-consuming and rising to broadcast when target plays the factor
In the case of time-consuming accounting, then obtains and broadcast time-consuming numerical value and act the numerical value for broadcasting time-consuming accounting.
Wherein, valuation functions are to broadcast time-consuming accounting as the linear function of variable, i.e. goal-based assessment to rise to broadcast time-consuming and rise
Function are as follows:
