Between be defaulted as 0, a data frame is only received in a cycle time if, when the above-mentioned target interval time can be the period
Between half, or according to receive/time for sending and the boundary value of cycle time determine above-mentioned target interval time, example
Such as receive/data-frame times that send are 1.5 seconds of cycle time, then can determine the target interval time be 1.5 seconds or
3.5 the second.
By taking server receives video frame as an example, it is assumed that the number of the video frame normally received in a cycle time lts
Amount is 5 frames, wherein the timestamp of the first video frame is vt1, the timestamp of the second video frame is vt2, the time of third video frame
Stamp is vt3, the timestamp of the 4th video frame is vt4 and the timestamp of the 5th video frame is vt5.Under normal circumstances when the period
The target interval time vts=vt5-vt1 of interior video frame, the size of vts and the size of lts are almost the same at this time.Such as Fig. 4,
If due to network fluctuation, a frame has been lacked in centre, and server receives a video frame less.This is in calculating cycle time lts
The target interval time of video frame, there will be vts=vt4-vt1；It is general within the next cycle time, if network is normal,
6 video frame vt5~vt10 can be received, at this time the target interval time of the video frame in lts of next cycle time there will be
Vts=vt10-vt5.Therefore, the fluency of target interval time response video frame can be passed through.
It is understood that since the data frame that network fluctuation was sent in a upper cycle time reduces, in order to reach stream
It is smooth to play, it needs to make up the data frame of upper period reduction in next cycle time as possible, therefore send out within next cycle time
The data frame relative increase sent, so as to cause the difference of target interval time and cycle time in former and later two cycle times section
Absolute value it is larger.It should be noted that if the target interval time in cycle time is less than cycle time, then show this week
Fluency in time phase is poor, if the target interval time in cycle time is more than cycle time, when showing a upper period
Interior fluency is poor.

In the present embodiment, the time set-up mode of above-mentioned preset time period can be configured according to actual needs, for example,
Can from send or receiving stream media data at the beginning of, calculate in each cycle time, the calculating cycle time with it is corresponding
The target interval time difference absolute value；It can also be calculated in for the previous period, often on the basis of current point in time
The absolute value of one cycle time and the difference of the corresponding target interval time.It below will be with transmission or receiving stream media certainly
It at the beginning of data, calculates in each cycle time, the difference of calculating cycle time and the corresponding target interval time
Absolute value for, be described in detail.
Specifically, all cycle time lts and corresponding target interval time vts can be subtracted each other, and take absolutely
To value, then it is added and obtains total value, fluency is waited until with the summation of total value divided by all cycle time lts.For example, can be with
It is calculated using following formula and obtains video fluency A：
Wherein, i indicates that i-th of cycle time, n indicate a total of n cycle time.
It should be noted that in other embodiments, average value can also be used, or increase according to the sequencing of time
Add and calculate the modes such as weight, calculates the assessed value for obtaining fluency.
In conjunction with referring to figure 6 and figure 7, in another assessment mode, can also be realized to fluency by way of drawing
Assessment.Specifically, above-mentioned steps 102 include：
The first waveform figure of time change reaction time is drawn according to each cycle time；
The of reaction target interval time change is drawn according to the target interval time of each same type data frame
Two oscillograms.
In figure 6 and figure 7, abscissa indicates that the time of machine passage, ordinate indicate interval time, and unit is millisecond
(ms).Referring to figure 6 and figure 7, it can be drawn to form cycle time variation waveform according to the time data of each cycle time, it can
Target interval time change waveform is formed to make to draw according to the time data of each cycle time corresponding target interval time.
As shown in fig. 6, since terminal or server are when executing operation, usually there is subtle fluctuation for the determination of time, because
The cycle time of this true statistics may exist subtle fluctuation, but be substantially close to 5 seconds.According to the comparison of Fig. 5 and Fig. 6,
Two waveform registrations are bigger, indicate that stream medium data is more smooth, and two waveform registrations are smaller, indicate that stream medium data more blocks
