Fig. 2 is the flow chart according to a kind of video broadcasting method shown in another exemplary embodiment, this video playback side
Method is applied in terminal, as in figure 2 it is shown, this video broadcasting method comprises the steps.
In step 201, video is obtained from server.
In a kind of possible implementation, terminal to server sends video acquisition request, in the request of this video acquisition
Carrying video labeling, server determines video according to this video labeling, and this video is sent to terminal, and terminal gets this
Video.
Terminal it needs to be determined that the numerical value of the image parameter of video, was broadcast according to the numerical value of this image parameter before playing video
Putting video, the numerical value of image parameter is used for indicating picture effect.Wherein, image parameter includes saturation, brightness, contrast and sharp
At least one in degree.Wherein, saturation refers to the bright-coloured degree of color, the also referred to as purity of color；Brightness refers to picture
Light levels；Contrast refer to light and shade region in picture the brightest in vain and the darkest specified black between the difference of different brightness degrees；
Acutance refers to image sharpness and the index of clear-cut margin degree.
Picture effect bad determined by the numerical value of the image parameter of some video, such as, saturation is too high to be led
Causing picture the most bright-coloured, therefore, in order to improve the picture effect of video, terminal can also arrange display pattern, by display mould
Formula regulates the picture of video.Wherein, display pattern includes at least one in saturation, brightness, contrast and acutance.Ratio
As, when the numerical value of the saturation in the image parameter of video is higher, the display pattern that the numerical value of saturation is relatively low can be selected
Play this video, to dim picture.
In the present embodiment, display pattern is soft pattern, mode standard, display mode, film mode, game mode etc.
One in Deng.The numerical value of the parameter that each display pattern comprises is different, such as, under soft pattern, the numerical value of parameter divides
Not Wei saturation 62, brightness 61, contrast 56, acutance 48, and under mode standard, parameter values is respectively saturation 65, bright
Degree 65, contrast 60, acutance 48.
Owing to the numerical value of the image parameter of different videos is different, therefore, terminal needs each video for playing to select
A kind of display pattern, with this display mode playback video.Wherein, display pattern can be determined by terminal, it is also possible to by server
Determine.When display pattern is determined by terminal, perform step 202；When display pattern is determined by terminal, perform step 207.
In step 202., when server does not provides the instruction information of display pattern, trigger and perform step 203.
When terminal does not receives the instruction information that server sends, terminal determines to be needed to determine display mould by terminal
Formula, now performs step 203.
Wherein, instruction information is used for indicating display pattern.In one implementation, server can be by display pattern
The numerical value of parameters is sent to terminal as instruction information, and terminal determines display pattern according to each numerical value.Owing to sending number
Value needs to take more transfer resource, and therefore, in another kind of implementation, server and terminal are according to same sequence rule
Then being ranked up display pattern, the sequence number of display pattern is sent to terminal as instruction information by server, and terminal is according to being somebody's turn to do
Sequence number determines display pattern.Now, by one sequence number of transmission, server just can notify which kind of display pattern is terminal use, joint
Save transfer resource.
In step 203, sample at least one picture frame from the video with the first display mode playback.
Picture frame is the single image picture of least unit in video.
First display pattern can be soft pattern, mode standard, display mode, film mode, game mode etc.
In one.First display pattern can be that terminal randomly chooses, it is also possible to being acquiescence, the present embodiment is not construed as limiting.
Owing to the first display pattern is not the picture and selecting according to video, with the picture of the first display mode playback video
Face effect may be bad, and therefore, the image parameter of video can also be analyzed by terminal, to select suitable second display mould
Formula plays this video.Owing to image parameter needs to obtain according to picture frame, therefore, terminal needs to sample at least one from video
Individual picture frame.
When not including advertisement video in video, terminal can be sampled when commencing play out video at least one picture frame；
When video includes advertisement video, owing to the image parameter of advertisement video is different from the image parameter of positive text video, if sampling
Be the picture frame in advertisement video, then the display pattern that terminal determines can be inaccurate, and therefore, terminal also needs to from positive text video
At least one picture frame of middle sampling.Now, at least one picture frame of sampling from the video with the first display mode playback, bag
Include: when determining that the terminal video with the first display mode playback is positive text video, from positive text video, sample at least one
Individual picture frame, positive text video is to play after advanced video and is the chosen video play in the terminal.
Wherein, advanced video can be the advertisement video play before positive text video, and positive text video can be in advertisement
Play after video, and be selected the video play in the terminal.
Generally, advertisement video has fixing playing duration, and therefore, terminal starts timing, when timing when playing video
When length exceedes preset duration, determine that terminal is playing positive text video, at least one picture frame of sampling from positive text video.Such as
The duration of advertisement video is 15s, then terminal starts timing when playing video, determines and commence play out positive text video after 15s,
The positive text video play after 15s is sampled at least one picture frame.
When sampling at least one picture frame from positive text video, terminal can randomly choose from the video play to
A few picture frame, or, terminal can select a period, at least one in this period of sampling from the video play
Picture frame；Or, owing to the picture frame in one period of sampling is the most unilateral, therefore, terminal can also select multiple discrete
Period, at least one picture frame in the plurality of discrete period of sampling.Now, sample from positive text video at least one image
Frame, including: within the broadcasting period of video, choose n period；The picture frame included in period each in n period is adopted
Sample, obtains at least one picture frame.
Such as, the playing duration of positive text video is 5 minutes, terminal can using the 1st minute to the 2nd minute as one time
Section, as a period, samples to the two period, obtains at least one picture frame for the 4th minute to the 5th minute respectively.
In step 204, obtaining the numerical value of the image parameter of at least one picture frame, the numerical value of image parameter is used for indicating
The picture effect of video.
Terminal gets the numerical value of every kind of image parameter in each picture frame, and calculates numerical value flat of every kind of image parameter
Average, using this meansigma methods as the numerical value of corresponding image parameter.Such as, using the meansigma methods of the numerical value of saturation as saturation
Numerical value, using the meansigma methods of the numerical value of brightness as the numerical value of brightness, the meansigma methods of the numerical value of contrast is spent as a comparison
Numerical value, using the meansigma methods of the numerical value of acutance as the numerical value of acutance.
When terminal calculates the meansigma methods of numerical value of image parameter, terminal can by the numerical value of all image parameters of the same race it
With the frame number divided by sampled image frames, obtain the meansigma methods of the numerical value of image parameter.Such as, the numerical value of saturation in two two field pictures
It is respectively 62 and 64, then the meansigma methods of the numerical value of saturation is 63.
In step 205, the second display pattern that the numerical value with image parameter matches is determined.
Second display pattern can be soft pattern, mode standard, display mode, film mode, game mode etc.
In one.
Refer to Fig. 3, determine the second display pattern that the numerical value with image parameter matches, including:
In step 2051, being input in preset algorithm by the numerical value of image parameter, preset algorithm is to each sample of sampling
Originally it is trained obtaining, the display pattern that sample is the numerical value of the image parameter of each video and user selects for video
Corresponding relation.
Terminal can gather substantial amounts of sample in advance, and uses machine learning algorithm to instruct sample
Practice, obtain preset algorithm.Wherein, machine learning algorithm can be k nearest neighbor algorithm or decision Tree algorithms, it is also possible to is that other are calculated
Method, the present embodiment is not construed as limiting.
The corresponding relation of the display pattern that sample is the numerical value of image parameter and user selects for video.Such as, depending on
The saturation 62 of image parameter, brightness 61, contrast 56, acutance 48 in Pin, user is soft for the display pattern that this video selects
And pattern, then sample 1 is saturation 62, brightness 61, contrast 56, the soft pattern of acutance 48-.Image parameter in video
Saturation 65, brightness 65, contrast 60, acutance 48, user is mode standard for the display pattern that this video selects, then sample of sampling
Originally 2 is saturation 65, brightness 65, contrast 60, acutance 48-mode standard.
After terminal obtains preset algorithm, the numerical value of image parameter is inputted in preset algorithm by terminal.Such as, image parameter
Numerical value be saturation 64, brightness 63, contrast 59, acutance 46, then by defeated to saturation 64, brightness 63, contrast 59, acutance 46
Enter in preset algorithm.
In step 2052, the second display that the output result of preset algorithm is matched as the numerical value with image parameter
Pattern.
In step 206, when the second display pattern is different from the first display pattern, continue to play with the second display pattern
Video.
When the second display pattern is identical with the first display pattern, terminal continues with the first display mode playback video；When
When second display pattern is different from the first display pattern, the first display pattern directly can be switched to the second display mould by terminal
Formula, continues to play video, to improve switching efficiency with the second display pattern；Or, terminal can ask the user whether to need by
First display pattern switches to the second display pattern, when the first display pattern is switched to the second display pattern by user's instruction,
First display pattern is switched to the second display pattern by terminal again.
Refer to Fig. 4, when the second display pattern is different from the first display pattern, continues broadcasting with the second display pattern and regard
Frequently, including:
In step 2061, detection the second display pattern is the most identical with the first display pattern.
If the number of the corresponding image parameter in the numerical value of the image parameter in the second display pattern and the first display pattern
When being worth identical, terminal determines that the second display pattern is identical with the first display pattern；If at least one image in the second display pattern
