Within enclosing.
The present invention proposes a kind of method for lifting Internet video definition.
Reference picture 1, in embodiments of the present invention, the method for the lifting Internet video definition, comprise the following steps：
S100, the data for receiving Internet video, decoding obtain the resolution ratio and code check of Internet video；
S200, resolution ratio and code check according to current network video, calculate the image quality compensation system of current resolution respectively
Number, and code check image quality penalty coefficient；
The image quality penalty coefficient of S300, the image quality penalty coefficient according to the resolution ratio and code check, adjustment Internet video
Definition.
It should be noted that the height of the definition of video is related to resolution ratio and code check.Under normal circumstances, resolution ratio is got over
Greatly, code check is bigger, and the definition of video is also higher.
Internet video, due to the limitation of network broadband, is compressed by height ratio, and its code check is relatively low.Carrying out video
During broadcasting, generally the resolution ratio of video and code check are adjusted, to obtain best definition.Set in the embodiment of the present invention
Put formula：
Definition=resolution ratio * (b1* noise reduction+c1* acutancees)+code check * (b2* noise reduction+c2* acutancees)；
Wherein, b1 is the related noise reduction coefficient of resolution ratio, and c1 is the related acutance coefficient of resolution ratio, and b1 and c1 is resolution
The image quality penalty coefficient of rate；

Repay coefficient.
As shown from the above formula, according to the resolution ratio and code check of video, corresponding image quality compensating parameter is calculated, is realized most
Big broadcasting definition.
Technical solution of the present invention is decoded by the data using the Internet video that will be received, and obtains Internet video
Resolution ratio and code check, by resolution ratio and code check, calculate the image quality penalty coefficient of current resolution respectively, and code check image quality
Penalty coefficient, then corresponding adjustment definition.For the Internet video of high compression ratio, technical solution of the present invention simultaneously to resolution ratio and
Code check is adjusted compensation, and relatively existing image quality adjustment simply adjusts resolution ratio, and inventive technique scheme effectively increases network
Definition during video playback.
Specifically, the resolution ratio and code check according to current network video, calculates the image quality of current resolution respectively
Penalty coefficient, and code check image quality penalty coefficient the step of include：
According to the resolution ratio and code check of current network video, default noise reduction function and acutance function are called, calculated respectively
Go out the noise reduction penalty coefficient and acutance penalty coefficient of current resolution ratio, and noise reduction penalty coefficient and the acutance compensation of code check are
Number.
Reference picture 2 and Fig. 3, generally, the standard resolution signal exported using reference instrument adjusts each different
Noise reduction coefficient b1 and acutance coefficient c1 below resolution ratio cause that image reaches preferable definition, draw respectively one group with point
Noise reduction numerical value and acutance numerical value that resolution changes and changes, can be calculated with change resolution by exponential smoothing algorithm
Noise reduction curve B1=fb1 (resolution ratio) of adjustment, acutance C1=fc1 (resolution ratio).
Reference picture 4 and Fig. 5, similarly, under a certain resolution ratio, reduce video code rate, by adjust noise reduction coefficient b2 (with
Code check is reduced and increases noise reduction) and acutance coefficient c2 (reducing acutance with code check reduction) so that the definition of low bit- rate is obtained
To compensation, the effect close with code check definition high is reached.Under each different code check, have recorded one group of noise reduction coefficient b2 and
One group of acutance coefficient c2, the noise reduction curve B2=fb2 (codes that can be adjusted in the hope of changing with code check by exponential smoothing algorithm
Rate) and acutance C2=fc2 (code check).
Therefore, the noise reduction function and the data of acutance function that will be obtained are pre-loaded to need the display device of compensation, root
According to different resolution ratio and code check, by calling noise reduction function and acutance function, the noise reduction compensation system of resolution ratio can be just calculated
Number and acutance penalty coefficient, and code check noise reduction penalty coefficient and acutance penalty coefficient.
Further, the image quality penalty coefficient and the image quality penalty coefficient of code check according to the resolution ratio, adjusts net
The step of definition of network video, includes：
Noise reduction penalty coefficient and acutance penalty coefficient according to current resolution ratio, and the noise reduction penalty coefficient of code check and sharp
Degree penalty coefficient, noise reduction coefficient and acutance coefficient needed for being calculated adjustment Internet video definition, according to noise reduction coefficient and
Acutance coefficient, adjusts the definition of Internet video.
Synthetic resolution and the effect with code check, can calculate：
Noise reduction function curve：B=B1+B2=fb1 (resolution ratio)+fb2 (code check)
Acutance function curve：C=C1+C2=fc1 (resolution ratio)+fc2 (code check)
Further, the image quality penalty coefficient and the image quality penalty coefficient of code check according to the resolution ratio, adjusts net
The step of definition of network video, further includes：
The specific gravity factor of specific gravity factor and code check according to resolution ratio, adjusts the definition of Internet video.
Further, the specific gravity factor sum of the specific gravity factor of resolution ratio and code check is 1, the model of the specific gravity factor of resolution ratio
The scope for enclosing the specific gravity factor for 0.6~0.8 and code check is 0.2~0.4.
What deserves to be explained is, influence proportion of influence and code check of the resolution ratio to video definition to video definition is not
The same, it is the definition for further optimizing video playback, the shadow of resolution ratio and code check to definition is measured according to actual experiment
Proportion is rung, formula is set：
Definition=a1* resolution ratio * (b1* noise reduction+c1* acutancees)+a2* code checks * (b2* noise reduction+c2* acutancees)；
Wherein, b1 is the related noise reduction coefficient of resolution ratio, and c1 is the related acutance coefficient of resolution ratio, and b1 and c1 is resolution
The image quality penalty coefficient of rate；
B2 is the related noise reduction coefficient of code check, and c2 is the related acutance coefficient of code check, and the image quality that b2 and c2 is code check is mended
Repay coefficient；
A1 is the specific gravity factor of resolution ratio, and a2 is the specific gravity factor of code check.A1 and a2 sums are 1, therefore, when a1 and a2 its
One of setting when, another one is also determined that.For example when a1 values are 0.7, a2 values are 0.3.
By the invention it is possible to lift image definition of the Internet video of low bit- rate when playing so that user obtains
More preferable image quality experience.
