To improve playing efficiency, reduce the stand-by period of user（During including between a sowing time with the wait in playing process
Between）, for data downloading process, present invention preferably employs asynchronous downloading mode.
In this method embodiment further preferred embodiment, rise to broadcast control condition and included and broadcast time threshold；On
State and identify and rise the method that Broadcast Control condition downloads the data to be played according to the address of data to be played, specifically include：Root
It has been used for the data volume for the data to be played broadcast according to threshold calculations between a sowing time；Then, according to for acting the data to be played broadcast
Data volume and address mark download and be used for the data to be played broadcast.
Wherein, the data volume of the above-mentioned data to be played for being used to broadcast can use following methods to calculate：
For acting the data volume of the data to be played broadcast=rise and broadcast the code check of time threshold × video to be played.
Step S103：The control condition broadcasting data to be played are broadcast according to rising；And calculate the data to be played
Played duration；
Step S104：Judge whether the played duration of data to be played is more than default playing duration；If so, go to step
S105；Otherwise S103 is gone to step to continue to play data to be played；
Default playing duration in the present embodiment refers to that system broadcasts the Rule of judgment that state enters normal playing status from.
Generally, time threshold is broadcast when having used（Prepare_Buffer_Duration）As rise broadcast control condition when, preset
Playing duration can be artificial experience arranges value, it can also be provided that when Prepare_Buffer_Duration is with minimum broadcasting
Between threshold value（Min-Buffer-Duration）Difference, can also be directly disposed as broadcasting time threshold（Prepare_Buffer_
Duration）.
Step S105：Obtain and play control condition, wait to broadcast according to remaining in broadcasting control condition download play buffer
Put data.
In the preferred embodiment, the broadcasting control condition can be preset as needed, can also be according to network rings
Border is set dynamically；When playing control condition and using mode set in advance, broadcasting control condition in step S105 can be with
Rising in step S102 is broadcast control condition while obtained, and can also be obtained again after broadcasting；Dynamic is used when playing control condition
During set-up mode, broadcasting control condition in step S105 preferably rise broadcast after obtain again.
This preferred embodiment broadcasts control condition by setting to play control condition and rise respectively, can ensure to rise as early as possible to broadcast
In the case of, effectively avoid picture from occurring once the situation for showing buffering, so as to preferably resolve existing player default
Buffering area it is bigger or be likely to result in the long bad experience problem of period of reservation of number in the case that network speed is slow.
Reference picture 2, the flow of video broadcasting method second embodiment of the present invention is shown, in the preferred embodiment, is adopted
Time threshold is broadcast with rising（Prepare_Buffer_Duration）Time threshold is broadcast with minimum be used as broadcast control condition control
Video rises and broadcasts process；Using minimum reproduction time threshold value（Min-Buffer-Duration）With highest reproduction time threshold value（Max-
Buffer-Duration）The video display process after broadcasting has been controlled as control condition is played, has been specifically included：
Step S201：Receive the video playback request for including data address mark to be played；
In the preferred embodiment, for ease of asynchronous process download and playing process, the system for performing methods described（Or dress
Put）Be provided with upper strata player and lower floor's player, lower floor's player has two types, including be responsible for live NuPlayer with
It is responsible for the StagefrightPlayer of program request, they all use identical buffer technology.Upper strata player can be according to number to be played
According to adress analysis judge its type, for live type, NuPlayer can be selected as lower floor's player and instantiated；For
Program request type, then StagefrightPlayer can be selected as lower floor's player and instantiated.Other modules will not become
Change.
Step S202：Obtain and broadcast control condition；
In this method embodiment, time threshold is broadcast by rising（Prepare_Buffer_Duration）With minimum sowing time
Between threshold value（Low_WaterMark_Duration）Control condition is broadcast as rising, is risen and is broadcast the sphere of action of control condition and only rising
Before broadcasting, control can be played out according to control condition is played after broadcasting.
By taking Android system platform as an example, upper strata player can use what is obtained to issue orders to play Broadcast Control condition setting
To lower floor's player：
setParameter（9500, Prepare_Buffer_Duration）；
setParameter（9501, Low_WaterMark_Duration）；
In mentioned order, 9500 and 9501 be the communication cryptology of upper strata broadcast unit and lower floor's broadcast unit agreement.
Prepare_Buffer_Duration effect be notice lower floor player need buffering can play how long
Data, lower floor's player can be calculated according to this time buffering data volume have it is much.In order to which image can be shown as early as possible
Out and rise broadcast after buffering situation will not occur at once, it is necessary to set one can not too small Prepare_ that can not be excessive
Buffer_Duration values；Too small to have caused occur buffering situation after broadcasting at once, user's impression is bad；It is excessive, need very
The existing picture of broadcast could be played for a long time, and user's impression is also bad.
If for example, defining Prepare_Buffer_Duration=1.5s, lower floor's player can be by being intended to play frequency
The code check in road calculates the data of 1.5s bufferings；Assuming that the code check of the channel is 1000KB, then required amount of buffered data（It is used for
Act the data volume for the data to be played broadcast）It is theoretical in the case where network speed is 2M/s bandwidth for 1000KB * 1.5s=1500KB
Finished as long as upper 0.75s can be buffered.
Above-mentioned Low_WaterMark_Duration（Minimum is broadcast time threshold）Effect be that play buffering pond is set
Low level threshold values, less than the value, player will suspend broadcasting, upper strata player is in loading states.Rise to set before broadcasting and be somebody's turn to do
The first purpose of value is to ensure that Low_WaterMark_Duration values are less than set by Prepare_Buffer_Duration
Value, and more than the actual playable time（As shown in Figure 4）, can guarantee that while quick broadcasting and protect as far as possible so that playing sowing time
Demonstrate,prove picture is not in upon the situation for showing just buffering.The threshold values that general Low_WaterMark_Duration is set compares
It is low, may only there was only hundreds of milliseconds, and Prepare_Buffer_Duration values may be several seconds.If for example, definition
Low_WaterMark_Duration is 200ms, it is assumed that the code check of the channel is 1000KB, then if the data volume of buffering area
It is less than（200ms / 1000）* 1000KB/s=200KB size, then broadcasting can be suspended.
Step S203：Data to be played are downloaded according to the address of data to be played mark is asynchronous；
By taking Android system as an example, upper strata player sends warning order prepareAsync (), and lower floor's player receives this
Order, can be according to the buffer condition set above（Rise and broadcast condition）, data to be played are downloaded, and be cached in buffering area.Lower floor
Player, can be by ordering onPrepared () to notify after data and other some data initializations work have been buffered
Upper strata player is in the state that can be played.
Step S204：Judge whether the data volume to be played in buffering area has met to broadcast time threshold；If so, go to step
S205 commences play out the data to be played in buffering area, while goes to step S206 and perform follow-up broadcasting control process；Otherwise, turn
Step S204 waiting steps S203 feedback result.
Step S205：Decode the data to be played in simultaneously output buffer；
In the case where meeting playing condition, upper strata player sends play command start (), and now lower floor's player enters
Enter broadcast state, be initially separated sound, video data, decode and do sound, audio video synchronization, export audio frequency and video.
In a further preferred embodiment, for avoid the data in buffering area reach or less than the actual playable time and
Cause to play the problem of abnormal, rise after broadcasting beginning, in addition to：Judge whether remaining data volume to be played is less than most in buffering area
Low is broadcast time threshold Low_WaterMark_Duration；If so, then suspend the decoding of data to be played, output procedure.
Step S206：Obtain and play remaining data to be played according to control condition is played.Obtain minimum reproduction time threshold
Value and highest reproduction time threshold value are as broadcasting control condition；According to the number to be played played in control condition play buffer
According to.
After broadcasting starts, start second and buffering area playing condition is set, after ensureing normal play, buffer time closes
Reason.Playing control condition includes minimum reproduction time threshold value（Min-Buffer-Duration）With highest reproduction time threshold value
（Max-Buffer-Duration）.
By taking Android system platform as an example, upper strata player can use the broadcasting control condition obtained to issue orders to set
To lower floor's player：
setParameter（9501, Min-Buffer-Duration）；
setParameter（9502, Max-Buffer-Duration）；
In mentioned order, 9501 and 9502 be the communication cryptology of upper strata broadcast unit and lower floor's broadcast unit agreement.
For example, it is 1s by the Prepare_Buffer_Duration times set, then timer can be after 1s again
Buffer size is set.Minimum reproduction time threshold value Min-Buffer-Duration and highest reproduction time threshold value Max-
Buffer-Duration can be used cooperatively, when minimum reproduction time threshold value Min-Buffer-Duration is more than actual can play
Between, and it is less than highest reproduction time threshold value Max-Buffer-Duration.When the anticipated playback time of buffering area remaining data is low
When the time that Min-Buffer-Duration is defined, pause plays.It is higher than when the time that buffering area remaining data can play
During Max-Buffer-Duration, buffering can be suspended, save other application request network data of the bandwidth for equipment.
Reference picture 3, show mutually closed in above-mentioned second method embodiment threshold value between sowing time, minimum broadcast time threshold,
Relation between the conditional parameters such as minimum reproduction time threshold value, highest reproduction time threshold value, actual playable time, wherein：
Highest reproduction time threshold value ＞ rise broadcast time threshold >=minimum reproduction time threshold value >=minimum broadcast time threshold >=
The actual playable time.
Above-mentioned reality can play the time for the time referring to can play video in theory, when the data volume in buffering area is only full
When full border can play the time, if the moment played can not obtain new data, playing process will force stop/pause,
It is possible that other play abnormal problem；
In addition, the setting of above-mentioned condition parameter is related to network environment, generally, act that to broadcast time threshold bigger
Reproduction time threshold value is broadcast in minimum；When network speed is very fast（When network speed of download is not less than video playout speed）, it is
Rise and broadcast as early as possible, reduce the stand-by period of user, can will rise and broadcast time threshold and be arranged to a relatively small numerical value, typically
It is equal that time threshold, minimum reproduction time threshold value, actual playable time value are broadcast with minimum；When network speed is slower, it is
Reduction suspending count, it can will rise and broadcast time threshold and be arranged to relatively large numerical value, and rise and broadcast time threshold ＞ most
Low reproduction time threshold value>Minimum is broadcast the time threshold ＞ actual playable times.
It should be noted that above-mentioned Broadcast Control conditional parameter and broadcasting control condition parameter, can be by art technology
Personnel provide according to various network conditions and the experience of oneself, can also be tested automatically by program network environment at that time,
The type and size of video to be played calculate the size of buffering area, so that netcast is more smooth.
Reference picture 4, show information exchanging process between the part included by the system of above-mentioned second method embodiment
Timing diagram, it is described as follows：
First, after upper strata player receives media play request, the address mark of data to be played is passed through into communication service
Unit forwards give lower floor's broadcast unit；
Secondly, upper strata player sets a Broadcast Control conditional parameter for lower floor's player by communication service unit；
Rise and broadcast control condition and included broadcasting time threshold Prepare_Buffer_Duration； Prepare_Buffer_
Duration effect is to tell lower floor's broadcast unit needs to buffer can play data how long.The effect of this setting
Scope only before rising and broadcasting, after broadcasting can the buffer size that sets in addition below of basis play out control.
3rd, upper strata player sends asynchronous data download instruction by communication service unit to lower floor's player, then,
Lower floor's player sends asynchronous data download request to data download unit；
4th, data download unit is joined to lower floor's player feedback download status information, lower floor's player according to buffering area
Number judges whether to commence play out, if it is then by communication service unit to upper strata player feedback status information；
5th, upper strata player sends video playback to lower floor's player by communication service unit and instructed；
6th, rise after broadcasting, upper strata player sets the broadcasting control condition of lower floor's player by communication service unit.
Wherein, above-mentioned broadcasting control condition parameter includes minimum reproduction time threshold value Min-Buffer-Duration and most
High reproduction time threshold value Max-Buffer-Duration；It is less than Min-Buffer- when the video data time in buffering area
During Duration, lower floor's player will suspend video display process, until the data that data download unit is downloaded in buffering area
It disclosure satisfy that broadcast request；When the video data time in buffering area being more than or equal to Max-Buffer-Duration, data
