Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Fig. 1 is the method for down loading schematic flow sheet of a kind of video slicing of the embodiment of the present invention, and as shown in Figure 1, the method comprises the steps:
Step 101, video server receives the download request of the video slicing of client transmission;
Step 102, video server, to client downloads current video burst, if complete in the time and download current video burst in first threshold, calculates the Second Threshold time that next video slicing is downloaded;
Step 103, if arrive the first threshold time, does not complete and downloads current video burst, will under the first code check of current video burst, be adjusted to second code rate; If complete in the time and download the current video burst that is adjusted into the second code check in first threshold, calculate the 3rd threshold time that next video slicing is downloaded; If completed in the time in first threshold, do not download the current video burst that is adjusted into the second code check, the second code check is adjusted into lowest bit rate.
If the code check of a upper video slicing is R 1, actual uplink time is t 1, burst duration is τ, and acquiescence burst duration is 2 seconds, and the download speed that goes up a video slicing is:
V 1 ( k , n ) = R 1 τ t 1 - - - ( 1 )
R wherein 1τ is the size of a upper video slicing, according to the download speed of a upper video slicing, utilizes adaptive algorithm (take RatedBased as example) to obtain the first code check R of current video burst 2.
T pk 2 = R 2 τ V 1 ( k , n ) - - - ( 2 )
V 2 ( k , n ) = R 2 τ t 2 - - - ( 2 )
R wherein 2τ is the size of current video burst, obtains the threshold time T of current video burst according to formula (2) pk2,, and the upload speed V that obtains current video burst according to formula (3) 2(k, n), utilizes adaptive algorithm to obtain the code check R of next video slicing according to formula (3) 3.
T pk 3 = R 3 τ V 2 ( k , n ) - - - ( 4 )
R 2for current video burst is the first code check, and current video burst is when first threshold completes download in the time, draws the threshold time of next video slicing, i.e. Second Threshold time T according to the download speed of current video burst pK3.
The first code check R when current video burst 2under be adjusted to second code rate R 21time, the download speed of current video burst can become:
V 21 ( k , n ) = R 21 τ t 21 - - - ( 5 )
According to formula (5), utilize adaptive algorithm to draw the code check R of next video slicing 31thereby, draw the threshold time of next video slicing, i.e. the 3rd threshold time T pK31.
T pk 31 = R 31 τ V 21 ( k , n ) - - - ( 6 )
In order to make full use of channel width and to guarantee that user watches smoothness and the high-quality of video, the present invention follows following four principles: (1) is avoided playing as far as possible and interrupted; (2) in the situation that allowing, bandwidth provides high-quality video segment as far as possible; (3) video switch number of times is few, because from user's angle, remains on the viewing experience that the video of low code check brings more always than the video constantly changing good between height code check always; (4) start time delay little, from user, selecting to play certain video, to first section of this video, to start time of playing as far as possible short.
In these four principles, first principle should have the highest priority, because causing the poorest user to experience is stagnation or the interruption of video playback, also just mean in order to guarantee the fluency of client video quality, can sacrifice to a certain extent the quality of video.Second and the 3rd principle need to be weighed, and the best method that makes full use of bandwidth is each video of selecting the highest code check of current network support, but this can make the switching times of video significantly increase in the network changing.Second and the 4th principle also needs to compromise simultaneously, because reduce startup time delay, just require first video segment shortest time of client downloads, can only ask minimum code check so for the first time, caused to a certain extent the waste of bandwidth, final judging process is in four principles, to weigh selection in the above.
The present invention follows above four principles and has proposed specific embodiment, the method for uploading application process schematic diagram of a kind of video slicing that Fig. 2 is the embodiment of the present invention, and as shown in Figure 2, this implementation process is:
Step 201, makes t=0, k=1, and t=0 is initial time, k=1 is for asking the burst of video to be numbered the first burst;
For really what minimum delay startup, by video the first burst S 1code check R 1be set as minimum code rate, i.e. R 1=R min;
Wait code check is R 1video slicing S 1downloaded, if code check is R 1video slicing S 1after download completes, forward step 202 to, otherwise forward step 203 to;
Step 202, code check is R 1video slicing S 1after download completes, burst k adds 1 automatically, i.e. k=k+1, and calculate video slicing S 1download speed V(k, n);
According to adaptive algorithm, draw video slicing S 1next burst S kcode check R k, S kestimate download time T pk, K=2, forwards step 204 to here;
Step 203, video slicing is waited for, and request is downloaded again;
Step 204 is R to code check kvideo slicing S ksend request, set count-down device T simultaneously ck,work as S kafter having downloaded, and count-down device T ckbe greater than 0 and be less than T pktime, forward step 206 to;
If described count-down device T ckequal 0, forward step 205 to;
Step 205, in advance by video slicing S kcode check R klower, forward step 207 to;
Step 206, timing is interrupted, and carries out video slicing S knext fragment request;
Step 207, first by video slicing S kcode check R kbe transferred to R k', R k' be less than code check R kmaximum, if occur to interrupt for the second time, forward step 208 to;
Step 208, by video slicing S kcode check R kbe transferred to code check R klowest bit rate R k=R kmin.
Symbol description involved in Fig. 2 is as shown in table 1:
Table 1
When the speed of download of a known front n fragment, we can be provided and be about to download fragment S by certain adaptive algorithm kcode check R k.This mode based on downloading estimates that the method for link bandwidth keeps away the unavoidable erroneous judgement to network speed, when especially having cache node in network.Suppose that the speed of download of calculating is V (k, n), the burst code check obtaining according to adaptive algorithm is R k, known burst duration τ, fragment S kestimate download time.Send after the request of this code check, consider the not intellectual of network, if we think, can download in the time, illustrate that network link approaches with expection, can continue further fragments to initiate request; Otherwise, mean that link circuit condition is than the bad luck of expection, or because nodes does not have this high code check fragment of buffer memory, for the wait that prevents that the longer time is futile, also avoid buffering area and occur because of empty grade the interruption of playing, our this request of premature termination also starts the low code check of this fragment to send request.
For the phenomenon that occurs waiting-timeout above, we should ask the file of the low code check of this fragment, but do not do concrete restriction about the setting of lower code check and the number of times of downward.Because, consider that user watches the continuity of video, user finishes watching the fragment S of certain video k, probably also seen fragment S k+1, in network, be cached with like this fragment S k+1possibility very large; Consider equally the impact of network-caching, same video, good than above of the average quality that the client of rear request watches, also discloses the fragment S for a video simultaneously k, the people who sees is many, also can buffer memory various code rate in network.In conjunction with above 2 points, lowering fragment S kcode check R ktime, the various code rate resource that can make full use of possibility buffer memory in network is lowered code check step by step, is adjusted to down for the first time R k=R k', request is downloaded.If there is no R k, but probably have the R of ratio kthe code check of low one or two grades, if this fragment S kinterrupt for the second time, for avoiding playing, stagnate, should be adjusted to down immediately R k=R kmin.
Above-described embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only the specific embodiment of the present invention; the protection range being not intended to limit the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
