The data of obtaining are carried out being written to this arbitrary data buffer zone after framing, the decoding.
Further, after these several data buffer zones are all full, when new data, new data buffer zone is set.
Wherein, these several data buffer zones are closed chain or formation.
Below by a concrete example first embodiment is described in detail; but this example does not constitute limiting the scope of the invention; in this example; it is example that the data buffering chain is deposited chain with frame; but protection scope of the present invention is not limited to frame and deposits chain, so long as utilization QOS mechanism, and by adding the data buffering chain; operating position according to buffer chain is inferred network condition, and then the adjustment broadcasting speed all is the protection range of this patent.The method of the played data that this example provides as shown in Figure 2, comprising:
201, QOS buffer size, frame are set deposit frame poke order frmNum, frame in the chain and deposit the frame of big or small frmTVal, reading speed kind and every kind of reading speed correspondence and deposit the numerical value interval of using number frmUsedNum.
In this example, frame is deposited chain and is deposited the closed chain of forming by frmNum size for the frmTVal frame, wherein, frame deposit big or small frmTVal refer to frame deposit in time interval of first frame and last frame.When the time interval of first frame and a certain frame is frmTVal in frame is deposited, judge that this frame deposits fullly, no longer in this frame is deposited, put into data, in actual applications, when judgment frame is deposited when expiring, the actual physical space may less than.Regulate reading speed because of there being frame to deposit chain, the QOS buffering area can be provided with littler, stops up unusually in order to prevent network, QOS generally will be provided with 2-5 second, and in this example, the QOS buffering area can be set to 0.5 second or littler, to the smooth performance network, can not cause excessive time-delay like this.
Wherein, can frame deposit chain and be set to the whole dynamic chain of an adjustable size, when frames all in the chain deposit all use after, there is new data to deliver to again, deposit in the chain at frame and insert one or more frames and deposit node this moment, and simultaneously, frame poke order frmNum increases the number that the frame that inserts is deposited node; If frmUsedNum is for a long time less than frmNum, delete frame is deposited in the chain some idle frames and is deposited.Also can limit a minimum value to the frame poke order frmNum that frame is deposited in the chain, for example can be set to the value bigger slightly than the numerical value interval value of 1 times of normal reading speed, can be this interval higher limit, deposits chain to avoid frequently revising frame; As frame poke order frmNum during greater than certain threshold values, for example can be set to the value bigger slightly than the numerical value interval value of 1.2 times of normal reading speeds, can be this interval lower limit, for example remind the user to close some other application programs.
Generally, the reading speed kind is when 0.8 times of normal reading speed is finely tuned between 1.2 times, and human eye comparatively is not easy to discover.Therefore, in this example, adopt five reading speeds such as 0.8 times, 0.9 times, 1 times, 1.1 times of normal reading speed and 1.2 times to carry out the adjustment of reading speed.Correspondingly, can deposit the numerical value interval of using frmUsedNum to frame and can be divided into five numerical value intervals, promptly the first numerical value interval is 0≤frmUsedNum＜m0, and at this moment, reading speed is 0.8 times of normal reading speed; The second value interval is m0≤frmUsedNum＜m1, and at this moment, reading speed is 0.9 times of normal reading speed; The third value interval is m1≤frmUsedNum＜m2, and at this moment, reading speed is 1 times of normal reading speed; The 4th numerical value interval is m2≤frmUsedNum＜m3, and at this moment, reading speed is 1.1 times of normal reading speed; The 5th numerical value interval is m3≤frmUsedNum≤frmNum, and at this moment, reading speed is 1.2 times of normal reading speed.
Wherein, in this example, the big or small frmTVal that each frame can be deposited is provided with littler, frame deposited frame poke order frmNum is provided with greatly in the chain, the frame of every kind of reading speed correspondence is deposited the interval meeting increase of the numerical value that uses number frmUsedNum like this, reduce the transmission number of times of message, improved system effectiveness.Be set to 0.6s as frmTVal, the frmNum value is 3, adopt 0.8 times of fast broadcast when frmUsedNum is 1, frmUsedNum is that 1 times of speed of 2 employings is play, and frmUsedNum is 1.2 times of speed broadcasts of 3 employings, then the every variation of frmUsedNum once, reading speed all will change, and needs to send the reading speed control messages to playing controller, and playing controller needs modification to read frame time at interval after receiving message, this can increase overhead, and is unreasonable; Be set to 0.2s as frmTVal, the frmNum value is 9, adopts 0.8 times of speed to play when 1≤frmUsedNum1≤3,4≤frmUsedNum≤6 o'clock, adopt 1 times of speed to play, 7≤frmUsedNum≤9,1.2 times of speed of some employing are play, after frmUsedNum changes, because of the interval under it not necessarily can become, therefore reading speed also not necessarily will change, reading speed is constant, does not then need to send the reading speed control messages, and this has just subtracted overhead.
Need to prove, take place that can increase the numerical value interval division of frmUsedNum, corresponding reading speed also can be done according to circumstances and adjust in order to prevent some unusual especially situations.For example, the situation especially little to the frmUsedNum value, for example, network continues for some time obstruction, adopts slower speed to play; To the king-sized situation of frmUsedNum value, for example, terminal is carried out other extra task sometime, and the resource that causes distributing to Streaming Media tails off, and adopts faster speed to read.
Wherein, in this example, an initial read threshold can also be set, deposit when frame and use number frmUsedNum to reach this threshold value, begin to read first.

206, continue framing, and the data behind the framing are delivered to ((i+1) mod frmNum) number frame deposit, wherein, ((i+1) mod frmNum) number frame is deposited and is the next frame that the i frame deposits and deposits node.
207, playing controller is got frame time at interval according to reading the control messages modification.
208, read frame data from the j frame is deposited sends to decoder to playing controller at interval according to the frame time of revising of getting, and decoder is decoded to the frame data that receive, and plays then;
Particularly, playing controller is not being received when reading control messages, adopt current reading speed after present frame is deposited reading of data, to send to decoder, receive read control messages after, continue at interval after the j frame is deposited reading of data, to send to decoder according to the frame time of revising of getting.
209, after the data read in the j frame is deposited is intact, frame is deposited use number frmUsedNum subtract 1.
210, frame is deposited use number frmUsedNum carry out interval judgement, if the numerical value interval under the frmUsedNum changes, then carry out 212; If do not change, then carry out 211.
After data in the j frame is deposited have been got, frame is deposited service marking be changed to " vacation ", simultaneously, frame is deposited use number frmUsedNum subtract 1.Need to prove that this example is frame to be deposited use number frmUsedNum to subtract 1 after frame is deposited sky, but protection scope of the present invention is not limited to this numerical value.If after the i frame is filled with, frame is deposited and is used number frmUsedNum to add 2, and then after depositing reading of data from the j frame, frame is deposited and used number frmUsedNum to subtract 2 accordingly, by that analogy.
Particularly, to judge whether its inside has data (whether service marking is " very "), and data are arranged, and reads frame data from the inside before reading frame data depositing from the j frame.Do not have data, then wait for appropriate time after, detect the j frame and have free of data: have then and read; Do not go again to detect after then continuing to wait for proper time.
Wherein, the span of j is 0≤j≤frmNum.
211, do not send and read control messages to playing controller.
