State video file and carry out video optimized process.
The embodiment of the present invention is by the way of Online Video optimizes fault self study, in video optimized equipment
Arranging an abnormal information table, this abnormal information table describes and cannot be carried out video optimized video file
Eigenvalue, as long as the video file that obtains from content providing of the most video optimized equipment obtains
The unique eigenvalue of this video file, then confirms in abnormal information table whether this feature value is recorded,
If having existed for this feature value in abnormal information table, then it is assumed that this video file cannot be carried out video
Optimizing, this video file is directly put logical process by the most video optimized equipment, does not affect end user's
Viewing experience.Improve the experience of user.
In the embodiment of the present invention embodiment of method for optimizing video is described below, and user video of the present invention optimizes
The embodiment of method is applied in video optimized running environment.
Step 301: mobile terminal sends video playback request to the content providing of SP, and this video is broadcast
The request of putting contains URL (the Uniform Resource of a video content specified
Locator, URL), this video playback request multiple network elements in wireless network are sent to video optimized
In equipment.
Step 302: video optimized equipment receives the request of above-mentioned video playback, and video playback request is sent out
Deliver in the content providing of corresponding SP.
The content providing of step 303:SP receives the request of above-mentioned video playback, obtains URL corresponding
Video file, and to mobile terminal send comprise this video file video playback response, this video is broadcast
Putting response and be specifically as follows response message, the body (body) at message carries this video file, and this rings
Message is answered to be sent to video optimized equipment through the Internet.
Step 304: video optimized equipment receives the response message of the content providing return from SP,
This response message contains video file.
Step 305: video optimized equipment according to the unique features value of predefined this video file of Rule,
This feature value can uniquely identify this video file.
Concrete, have the predefined rule of the following two kinds to carry out eigenvalue acquisition:
1, obtain eigenvalue according to the URL keyword section of this video file, but the method can be limited to SP,
When the URL definition rule of SP changes, need synchronized update eigenvalue acquisition methods.
Such as: the URL for certain video resource of a certain SP is:http://119.147.97.13/youku/6775432A73E3681FB986A3596C/03002001005232C 2FF32D405CF07DDC3F94277-252A-DD76-DD74-80.mp4, wherein
03002001005232C2FF32D405CF07DDC3F94277-252A-DD76-DD74-80 is one
Immobilize part, and this can uniquely identify this video file on this SP.But the method can be limited to
SP, when URL definition rule is changed by SP, needs synchronized update Eigenvalue Extraction Method.Should
During by this rule, video optimized equipment needs to obtain each SP setting the URL of video from each SP
Putting rule, and therefrom acquisition can fix the part representing video file, the most video optimized equipment is the most permissible
Each video file in next time obtained same SP carries out eigenvalue acquisition.
2, according to the contents extraction eigenvalue of this video file, the most video optimized equipment utilization eap-message digest
Algorithm the 5th edition (message digest algorithm 5, MD5) is in the front 32K byte of video file
Hold generation calculate, it is thus achieved that the eigenvalue that data value is this video file, the method is not only restricted to SP,
But can additionally consume certain calculating resource.
Step 306: video optimized equipment determines that whether the eigenvalue of the video file of above-mentioned generation is at abnormal letter
Breath table, if the eigenvalue of the video file of above-mentioned generation is at abnormal information table, then shows this video file
Cannot successfully carry out online transcoding optimization, video optimized equipment puts this video file logical, not to this video literary composition
Part carries out video optimized, it may be assumed that directly by video file transfer to mobile terminal.If regarding of above-mentioned generation
The eigenvalue of frequency file not at abnormal information table, then shows that this video file may can be implemented in line at present
Transcoding optimizes, and continues step 307.
In video optimized equipment, store abnormal information table, this abnormal information table includes each video
Optimization equipment has been optimized process, and optimizes the eigenvalue processing unsuccessful video file, this
If certain video file of sample is determined cannot be carried out video optimized process for the first time, this video follow-up
When file is asked to play again, video optimized equipment according to the eigenvalue of this video file in abnormal information
In table, it is possible to determine that this video file cannot be carried out Online Video optimization and processes, then directly to this video
File carries out putting logical process, thus carries and has done video optimized efficiency, has saved video optimized equipment
Resource receives the waiting time of video file with decreasing mobile terminal.
Abnormal information table can also record video file corresponding to this feature value and come from which SP, so
After a certain time, SP in abnormal information table just can be added up by video optimized equipment, for statistics
One or more SP most in result, just say that the video file of the one or more SP itself may be deposited
In problem, can be reacted to corresponding SP by attendant or video optimized equipment.
Step 307: this video file is carried out at Online Video optimization by video optimized equipment according to optimisation strategy
Reason, if Online Video optimizes successfully, then the video file after optimizing is sent to mobile terminal, if
Online Video occurs abnormal in optimizing, i.e. Online Video optimizes unsuccessful, then by the feature of this video file
Value joins in abnormal information table, in order to subsequent video optimizes equipment and this video file does not do optimization process,
And this time video-see will be interrupted, say, that video optimized equipment will stop sending above-mentioned to terminal
This video file.
Here optimisation strategy can following several classes: according to the terminal screen resolution size of user to video
The resolution of file carry out transcoding adaptive or according to the current effective access bandwidth dynamic of user to video
The code check of file carries out transcoding adjustment etc..When optimisation strategy is specially the terminal screen resolution according to user
When size is optimized, then the video playback of step 301 asks also to include the resolution of the terminal screen of user
Rate size, the terminal screen resolution size that video optimized equipment is asked according to video playback, come video
File is optimized process.When optimisation strategy is with being specially current effective access bandwidth dynamic to video literary composition
The code check of part carries out transcoding adjustment, and the most video optimized equipment also needs to obtain current effective access of terminal
The size of bandwidth, after obtaining the size of current effective access bandwidth of terminal, video optimized equipment root
According to acquired value, carry out video optimized.
Video optimized specifically include: adjust video code model, resolution, frame per second or code check.
Once transcoding optimization, by the way of Online Video optimizes fault self study, is lost by the embodiment of the present invention
The video lost carries out putting logical process, does not affect the viewing experience of end user.As some video file VO
When equipment cannot successfully carry out the optimization of online transcoding, only affecting the viewing first of this video, follow-up viewing is not
Can be the most impacted.
