To make the object, technical solutions and advantages of the present invention express to be more clearly understood, with reference to the accompanying drawing and specifically
The present invention is further described in more detail for embodiment.
Fig. 1 is the flow diagram of the method for the setting caching of one embodiment of the invention.
As shown in Figure 1, the method for setting caching may comprise steps of: S110 obtains behaviour when user watches video
Make parameter；S120 is based on operating parameter, identifies the operating habit of the user；S130 is based on operating habit, the appearance of caching is arranged
Measure size.
In some embodiments, operating parameter may include in following item at least one of: searching times, the direction of search and
Search rate.
In some embodiments, operating habit can also include: the habit of F.F. and/or the habit of rewind.
The operating parameter when embodiment of the present invention watches video by obtaining user, identifies the user's based on operating parameter
Operating habit, and be accustomed to not only agreeing with user demand, Er Qiejie the size of buffer memory capacity is arranged depending on the user's operation
The about quantity flow of terminal resource and user, and the normal use of Logistics networks resource.In addition, passing through flexible setting buffer memory capacity
Size, can dynamically distribute and adjust the cache resources of server end and terminal side, thus reduce terminal and server end burden,
And existing network and terminal resource are made full use of, reach better user experience.
In some embodiments, it is based on operating habit, the step of amount of capacity of caching is arranged (i.e. S130) may include:
When the number of F.F. or frequency reach preset threshold value, increase before to buffer area size.
In some embodiments, the step of being based on operating habit, the amount of capacity of caching is arranged (i.e. S130) can also wrap
It includes: when the number of operations of rewind or frequency reach preset threshold value, increasing the size of backward buffer area.
In some embodiments, the step of being based on operating parameter, identifying the operating habit of the user after (i.e. S120),
It is further comprising the steps of: the account of the operating habit of user and user are bound.
In some embodiments, the tactful implementation for being arranged for user operation habits or adjusting buffer memory capacity can
With are as follows:
It obtains user and watches the progress bar seek operation information during similar video, the including (F.F./fast of the direction seek
Move back), seek number or seek frequency.It operates more frequent then corresponding size and ratio is bigger, analyze and record user's use
Seek habit and feature.To seek buffer size before increasing when being operated before user's frequent progress to seek.When user's frequency
To buffer size after increasing when after numerous progress to seek.
1) when being adjusted substantially without progress bar when a certain user watches video, using the cache policy of default；
The buffer setting parameter of default be the user obtained by server initial value or video APP it is preset initially
Value, including buffer area size of population, forward direction/backward buffer size cache speed bit stream threshold value of acquisition etc..Wherein pass through clothes
The initial value that business device obtains can be server and provide different templates according to different zones and user group.
2) when there is frequent forwarding operation when detecting that a certain user watches video, such as in 30 minutes video playings
The number of F.F. reaches 5 times or more in time, then increases the size of user cached backward, or working as is that caching total amount is fixed
When Circular buffer video, increase wherein caching accounting size backward.Similarly, if user frequently review before content, increase
The size or caching accounting of forward direction caching.
3) in view of the buffer setting of default may have been able to the operation for meeting user's F.F. or rewind, terminal can be with
Consider user's fast forwarding and fast rewinding operation the frequency on the basis of further detect, user's F.F. or step back fastly whether need to wait it is slow
Load is deposited, such as (time point that request plays lags behind current play time point 10 when user only carries out F.F. by a small margin
Second or so) existing cache policy can support the direct viewing of user's not Caton, if but user carries out significantly F.F.
When (request play time point lag behind current play time point 10 minutes or so) terminal will perceive user and need to wait
Caching reloads, i.e., existing cache policy is not able to satisfy the broadcasting habit of user.User's skip forward/back is recorded by analysis
The frequency for waiting caching to load is needed afterwards and then the size or accounting of forward or backward caching are adjusted.
When operating after user's frequent progress to seek, terminal can tune up caching in threshold value on the basis of initial value and obtain
Speed is to facilitate viewing to film source after quickly filling.And when more to seek operation before user, then suitably it can reduce or protect
Hold constant terminal buffers acquisition speed.
Fig. 2 is the flow diagram of the method for the setting caching of another embodiment of the present invention.
As shown in Fig. 2, the method for setting caching may comprise steps of: S110 obtains behaviour when user watches video
Make parameter；S120 is based on operating parameter, identifies the operating habit of the user；S140 is based on operating habit, current in conjunction with user
Select the piece Source Type, piece source format and the amount of capacity for playing one or more setting cachings in situation of the video of viewing.
In some embodiments, it is based on operating habit, piece Source Type, the film source of the video of viewing are currently selected in conjunction with user
(i.e. S140) may include: when film source class the step of the amount of capacity of one or more setting cachings in format and broadcasting situation
When type is program request type, the total capacity of caching is dimensioned to fixed value.
In some embodiments, it is based on operating habit, piece Source Type, the film source of the video of viewing are currently selected in conjunction with user
(i.e. S140) can also include: to work as film source the step of the amount of capacity of one or more setting cachings in format and broadcasting situation
When type is live streaming, the total capacity of caching is dimensioned to change value.
In some embodiments, the step of total capacity of caching being dimensioned to change value may include: any increase
The size of forward direction caching in caching.
In some embodiments, the method that caching is arranged can be executed for example by the caching identification module of terminal side, caching
Module and Circular buffer area complete jointly.
In some embodiments, the caching identification module of terminal side is core, is responsible for identification, analysis and record terminal side
Related played data, according to user's use habit (including the piece Source Type liked, the video including program request, live streaming and film source
The seek carried out operation, such as number, direction and the frequency of seek are liked in format and content source), in conjunction with the net of active user side
Network situation (for example, under different user use habit, the practical code stream acquisition speed in different content source, network delay and shake
Situation etc.), provide the parameter recommendation of caching adjustment.
In some embodiments, the implementation for being arranged for piece Source Type or adjusting cache policy specifically can be as follows
It is shown:
The piece Source Type played when determining user using the application program, as program request is still broadcast live, by order video
Caching total amount is set as fixed value, i.e., the video of program request is handled by Circular buffer；The caching total amount of live video is set as changing
Value, i.e., forward direction caching therein can infinitely increase, review at any time convenient for user.And it caches can be set to biggish fixation backward
It is worth perhaps load as much as possible or the caching total amount of live video can also be also set as change value, but is greater than program request
The caching total amount of video, and increase accordingly preceding to cache size.
A possibility that completely reviewing in view of order video user is little, therefore can save terminal using Circular buffer
Memory source；And for live video, it is contemplated that user may be reviewed without the time during live streaming before segment, therefore
To caching before wouldn't deleting, after terminating live streaming, user can mend see before the segment missed, and the backward caching being broadcast live
(load i.e. as much as possible) without restriction, to guarantee the real-time of live streaming.
When most code rate is all that code rate is bigger than normal in the film source that user plays, terminal can be on the basis of initial value in threshold
Caching acquisition speed is tuned up in value to facilitate viewing to film source after quickly filling.And when the film source major part code rate of user's broadcasting
When less than normal, then terminal buffers acquisition speed suitably can be reduced or remain unchanged, when user plays big code rate film source just according to feelings
Condition increases.
It in some embodiments, specifically can be as follows for the implementation of film source Format adjusting cache policy:
Because of the film source of various formats, its data volume is of different sizes, it is therefore desirable to based on piece source format dynamic adjustment video cache
Size to guarantee operating time of the skip forward/back of user.Such as the caching of 100M can expire when film source is H.264 format
Foot off-line browsing in 80 seconds, but when film source is H.265 format, the caching of 100M is able to satisfy off-line browsing in 160 seconds, in order to make
The unobvious perception of user caches difference, needs a certain proportion of cache size by weight of piece source format is it.
When compression ratio most of in the film source that user plays is lower, terminal can tune up in threshold value on the basis of initial value
Caching acquisition speed is to facilitate viewing to film source after quickly filling.And when the film source major part partial pressure shrinkage that user plays is higher
When, then it suitably can reduce or remain unchanged terminal buffers acquisition speed.
It in some embodiments, specifically can be as follows for the mode of network condition adjustment cache policy:
When more network Caton and delay occurs in the film source that the user plays, notice caching execution module is suitably turned up
Buffer area entirety size and caching acquisition speed, so that the bigger possibility read backward can be obtained during network fluctuation
Property, and when the film source played the very smooth and few situation of Caton situation, it can suitably turn down cache size and caching obtains
Speed reduces the expense of terminal overheads and server end.
The content in caching can be filled, and it is related to be responsible for feedback by caching execution module according to setting parameter
Execute data.Circular buffer is filled backward first when the content of entire buffer area is less than.When entire buffer area
Man Shi, then replaced the content of oldest caching by the content of newest caching, but the content replaced do not exceed video playing into
Degree point.
The result of execution and relevant parameter can also be reported to server by caching execution module, it is especially desirable to report
User operation habits are stated, because of this adjustment and user's strong correlation, and the maximum probability reasonability in order to keep parameter to adjust, other
Several adjustable strategies be also all watched in the recent period to user content and network condition dynamic adjustment synthesis result it is related.Server obtains
The user operation habits of each account and preservation are taken, when being logged in next time so as to user, the user operation habits deposited can be issued to
Current registration terminal, so that present terminal is adjusted the cached parameters in the terminal according to user's habit and network condition.
Below by taking user watches video as an example, the implementation of buffer setting method is illustrated, this method includes following
Step:
Step 1, user logs in, and obtains user account information；
Step 2, user cache setting is obtained；
If server side does not preserve the habit parameter of the user, user cache is set as region the type use at this time
The default buffer setting at family, and to step 3；If server side has the operating habit parameter of the user, such as habit is frequently returned
It sees, then the habit is issued to the application of user's present terminal, and to step 4；
Step 3, user watches order video, while carrying out frequent backward seek operation, and Network status is splendid at this time, this
When can suitably reduce the buffer size of user terminal, it is appropriate be turned up after to seek buffer area ratio, while notifying server
End suitably reduces caching code stream acquisition speed in range.
Step 4, user plays HLS type direct-broadcasting code stream, because user's habit is frequently reviewed, to caching before tuning up
(or unlimited forward direction buffer memory)；Again because Caton and delay situation it is more apparent, caching identification module notice caching execution module into
One step big buffer size facilitates user to obtain in the case where code rate changes greatly to buffer area ratio before appropriate adjustment
More forward direction cachings, optimization user play experience.
In the present embodiment, total size, forward direction cache size, backward cache size and terminal are specifically cached and obtains caching speed
The implementing result of degree, the comprehensive generation of judging result with above situation 1, situation 2, situation 3 and situation 4, for example will always cache big
It is small to be divided into 7 grades from 1 to 10, it becomes larger.Forward direction cache size is from 2 to 10, and backward cache size is from 0 to 8.Cache acquisition speed
It is divided into 5 grades from a to e, becomes larger.So a certain item adjustment result by situation 1 factor * situation 1 coefficient+situation 2 because
The coefficient of the factor * situation 4 of coefficient+situation 4 of the factor * situation 3 of coefficient+situation 3 of sub- * situation 2 obtains synthesis result.
Such as forward direction cache size, when a variety of situations occur simultaneously, for example situation 1 and situation 2 occur simultaneously, situation 1
User, which likes frequent forward direction, can see that operations factor is 2, and coefficient is defaulted as 2；The case where situation 2, user watches live streaming code rate, accounts for
90% or more, operations factor 2, coefficient is defaulted as 4；Situation 3 and situation 4 meet default situations, then to the shadow of caching before tuning up
Ringing value is 12, to the size of caching before foundation reduced value suitably tunes up at this time.The film source that user plays in the recent period simultaneously frequently occurs
Caton situation, operations factor 2, coefficient is defaulted as 2, then the influence value for tuning up buffer size on this basis is 4, that
Can execution module can integrate and tunes up whole buffer area, while to the size and ratio of buffer area after being tuned up according to influence value.Tool
The relationship of the operations factor of body, the calculation method of coefficient and influence value and parameter setting and implementing result all can be according to particular user
Service condition and effect are preset and subsequent adjustment.
Can identify through the foregoing embodiment as a result, analyze to record terminal side related played data, made according to user
With habit, (including the piece Source Type liked, video format and content source including program request, live streaming and film source like progress
Seek (search) operation, such as number, direction and the frequency of seek), in conjunction with active user side network condition (for example, not
With under user's use habit, the practical code stream acquisition speed in different content source, network delay and jitter conditions etc.), provide caching
The parameter recommendation of adjustment.
