Abstract
The invention discloses a kind of video broadcasting method and system, user is prompted to download designated in advance, or according to the video-see behavior of user, predicts the video of hit；Judge whether memory space is N times or more of video file size for needing to download, if not, then it is assumed that insufficient space, repetition judge whether memory space is N times or more of the video file size that needs are downloaded；If so, downloading queue, which is added, in video task judges whether current time is in the CDN bandwidth peak time in terminal network free time, start downloading if being not at the CDN bandwidth peak time；Judge locally whether there is buffered video, has and then directly play local video, then CDN is not requested to pull video flowing.The present invention needs the probability by Real time request CDN video when can reduce video playing, to reduce the probability for Caton occur, playing failure, promoted and play experience；The probability for reducing access CDN in the CDN bandwidth peak time, to reduce bandwidth expense.
Description
Technical field
The present invention relates to video broadcasting field, specifically a kind of video broadcasting method and system.
Background technique
Video broadcasting field, user is if necessary to watch a video, by a video flowing address, from CDN(content point
Hairnet network) in real time foradownloaded video data play out.During video flowing is pulled from CDN, it is possible to can be because of network jitter
Or network quality it is long-term it is poor etc. there is the case where video playing Caton, cause to play experience bad, it is also possible to because making
Lead to flow consumption problem with cellular network broadcasting.
User concentrates behavior using video APP having time simultaneously, will form a CDN bandwidth peak, video is caused to provide
There is higher CDN network bandwidth expense in quotient.
There are following Railway Projects for the prior art:
1. viewing video is required to download in real time from CDN every time, because the probability that Caton occurs in network problem is high；
2. user's viewing time is more concentrated, bandwidth peak is formed, causes video provider CDN bandwidth costly.
Summary of the invention
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, providing a kind of video broadcasting method and being
System, by way of active prompt and active predicting, in conjunction with bandwidth peak estimate of situation, in advance by video push to user terminal
On, when reaching user's viewing video, without the purpose of real-time foradownloaded video.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of video broadcasting method, including it is following
Step:
1) prompt user downloads designated in advance, or according to the video-see behavior of user, predicts the video of hit；
2) judge whether memory space is N times or more of video file size for needing to download, if not, then it is assumed that insufficient space,
Repeat step 2；If so, entering step 3)；
3) downloading queue is added in video task, in terminal network free time, judges whether current time is in CDN band broad peak
It is worth the time, starts downloading if being not at the CDN bandwidth peak time, the return step if in the CDN bandwidth peak time
2)；
4) judge locally whether there is buffered video, have and then directly play local video, then CDN is not requested to pull video flowing.
In the present invention, N=5.
Correspondingly, the present invention also provides a kind of audio/video player systems comprising:
Prediction module, for prompting user to download designated in advance, or according to the video-see behavior of user, prediction hit
Video；
First judgment module, for judging whether memory space is N times or more of video file size for needing to download, if it is not,
Then think insufficient space, repetition judge whether memory space is N times or more of the video file size for needing to download, up to space
Abundance executes the operation of the second judgment module；If so, executing the operation of the second judgment module；
Second judgment module judges that current time is in terminal network free time for downloading queue to be added in video task
It is no to be in the CDN bandwidth peak time, start downloading if being not at the CDN bandwidth peak time, if being in CDN bandwidth peak
Time then executes the operation of first judgment module；
Playing module has for judging locally whether there is buffered video and then directly plays local video, do not request CDN then
Pull video flowing.
Compared with prior art, the advantageous effect of present invention is that: the needs when present invention can reduce video playing
By the probability of Real time request CDN video, to reduce the probability for Caton occur, playing failure, is promoted and play experience；It reduces
The probability of access CDN in the CDN bandwidth peak time, to reduce bandwidth expense.
Detailed description of the invention
Fig. 1 is that the present invention pushes away video download flow chart in advance；
Fig. 2 is that the present invention pushes away video playing flow chart in advance.
Specific embodiment
1. actively prompting user to download designated in advance in video software interface button, user chooses video necessarily to order
In；Active predicting analyzes video-see behavior inside video software: according to the video-see behavior of user, predict the hit which
Video.It has seen a TV play collect more before such as, and has had updated new collection of drama and then hit.Synchronous one has repeatedly been seen before such as
It portion's video and does not finish watching, then hits；
2. judging whether memory space is enough after hitting video according to step 1, (memory space is desirable to memory space enough
5 times or more of the video file size of downloading) then hit, otherwise it is assumed that insufficient space, cannot influence equipment runnability；
3. after the hit of step 2 memory space, downloading queue is added in video task, in terminal network free time, judgement is worked as
Whether the preceding time is in the CDN bandwidth peak time, starts downloading if being not at the CDN bandwidth peak time, if being in CDN
The bandwidth peak time then continues poll；
First judge locally whether there is buffered video when video playing, has and then directly play local video, then CDN is not requested to draw
Take video flowing.
Claims (4)
1. a kind of video broadcasting method, which comprises the following steps:
1) prompt user downloads designated in advance, or according to the video-see behavior of user, predicts the video of hit；
2) judge whether memory space is N times or more of video file size for needing to download, if not, then it is assumed that insufficient space,
Repeat step 2；If so, entering step 3)；
3) downloading queue is added in video task, in terminal network free time, judges whether current time is in CDN band broad peak
It is worth the time, starts downloading if being not at the CDN bandwidth peak time, the return step if in the CDN bandwidth peak time
2)；
4) judge locally whether there is buffered video, have and then directly play local video, then CDN is not requested to pull video flowing.
