Dq_rate=dq_count/dq_int
Wherein, dq_count for this calculating time interval in dequeue data volume summation, dq_int for calculate when
Between be spaced；
The dequeue speed dq_rate of smooth currently transmitted queue, calculates queue and averages out queue rate avg_dqrate：
Avg_dqrate=ε × avg_dqrate+ (1- ε) × dq_rate
In formula, ε represents smoothing factor；
Then the queue transmission delay dq_delay computational methods of package are as follows：
Dq_delay=qsize/avg_dqrate
In formula, qsize represents the total amount of data size of the package of this in queue and all packages before the package.
Further, the propagation delay time trans_delay is monitored by the transmission to package, measures a upper envelope
The required time is successfully transmitted or be eventually discarded after bag dequeue, is used as the propagation delay time trans_delay of current package.
Further, the sweep limits set in the step S1, it is determined by parameter alpha；The parameter alpha be 0 to 1 between
A numerical value；Queued scans scope is α * queue lengths, and parameter alpha is a preset constant or enters action according to network condition
State changes.
Further, carried out in the step S3 by strategy discarding, its drop policy includes：
In the sweep limits of queue, if the I frames that the package abandoned belongs in H.264 code set GOP, are abandoned same
All frames in GOP；If the P frames that the package abandoned belongs in H.264 code set GOP, need to abandon to rely in same GOP and be somebody's turn to do
Other P frames of P frames and B frames.
Further, carried out in the step S3 by strategy discarding, its drop policy includes：
If the I frames that the package abandoned belongs in H.264 code set GOP, retain this I frame, since the frame position backward
The package in the same GOP in queue is traveled through, and abandons all packages of the 1st B frame found；If B frames envelope can not be found
Bag, then abandon all packages of the 1st P frame found；If can not still find, since queue is traveled through forward the frame position
Previous GOP in package, abandon the 1st all packages of B frames found；If B frame packages can not be found, the 1st is abandoned
All packages of the individual P frames found；If the P frames that the package abandoned belongs in H.264 code set GOP, temporarily retain this P frame,
The package in same GOP since queue is traveled through backward the frame position, and abandon all envelopes of the 1st B frame found
Bag；If B frame packages can not be found, the package in same GOP since queue is traveled through forward the frame position abandons the
1 all package of B frames for finding；If can not still find, all packages of current P frames are abandoned；If current package belongs to B frames,
Then directly abandon all packages of the frame.

Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combine, the application is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the frame losing control method that a kind of low latency real-time video Streaming Media proposed by the present invention is wirelessly transferred,
That includes following steps description.
Step one：By the virtual transmission time delay estimation module of server end, to the package in server end transmit queue
From first to last scan, and judge package whether in the sweep limits of setting, if in the virtual transmission time delay progress to package
Calculate；If it is not, then terminating.
Virtual transmission delay packet stops time delay, queue transmission delay and the part of propagation delay time three containing queue.
Vir_trans_time=wait_delay+dq_delay+trans_delay
The computational methods that wherein queue stops time delay are, when each package enters the transmit queue of server end, record
The current time enqueue_time of system, when the package in algorithm scanning transmit queue, the current time of record system
Current_time, then queue stop time delay wait_delay be：
Wait_delay=current_time-enqueue_time
The computational methods of queue transmission delay are that the packed byte sum dq_count of the accumulative dequeue of initialization is 0, when
During package dequeue, the current time last_dequeue_time of record system, dq_count adds up the byte number of the package；
When follow-up package dequeue, dq_count adds up out the byte number of group package；
When the packed byte sum dq_count of accumulative dequeue exceedes given threshold value dq_count_threshold, note
The current time current_dequeue_time of recording system, calculates time interval dq_int, as follows：
Dq_int=current_dequeue_time-last_dequeue_time
Based on above-mentioned dq_int, the dequeue speed of currently transmitted queue is estimated, it is as follows：
Dq_rate=dq_count/dq_int
Wherein, dq_rate is to calculate the dequeue speed for obtaining current queue, and dq_count is this calculating time interval
Interior dequeue data volume summation, dq_int is the time interval calculated.
The dequeue speed of smooth currently transmitted queue, calculates queue and averages out queue rate avg_dqrate：
Avg_dqrate=ε × avg_dqrate+ (1- ε) × dq_rate
In formula, avg_dqrate is averages out queue rate, and ε is smoothing factor.
Then the queue transmission delay dq_delay computational methods of package are as follows：
Dq_delay=qsize/avg_dqrate
In formula, qsize is the total amount of data size of the package and all packages before the package in queue.
Propagation delay time trans_delay is monitored by the transmission to package, measure after a upper package dequeue into
Work(sends or is eventually discarded the required time, is used as the propagation delay time of current package.
Step 2：The from first to last package in scanning transmit queue head in sweep limits, and according to being obtained in step one
The virtual transmission time delay of each package, is compared with default frame losing delay threshold, and it is big to abandon virtual transmission time delay by strategy
In the package of frame losing delay threshold.
From the beginning specific embodiment is travels through queue, and initialization package counter pkt_count is 0, often travels through one
Package, counter pkt_count adds 1, if current pkt_count is less than or equal to queue length queue_length and scale factor
α product, then calculate the virtual transmission time delay vir_trans_time of current package by step one, with frame losing threshold value drop_
Threshold compares.
If less than threshold value, the package is retained；If more than threshold value, package is removed into queue by frame losing strategy.
The present invention can be from 2 kinds of frame losing strategies according to complexity：
The relatively low frame losing strategy one of complexity is, if the I frames that the package abandoned belongs in H.264 code set GOP, from the frame
Position starts to travel through queue backward, and same GOP other P frames, B frame packages in transmit queue are together removed into queue.If losing
The P frames that the package abandoned belongs in H.264 code set GOP, then will rely on other P frames and B frames package one of the P frames in same GOP
With removal queue.
The complexity of packet loss strategy two is higher, but can preferably improve video transmission quality.If the package abandoned belongs to
H.264 the I frames in code set GOP, then retain this I frame, in the same GOP since queue is traveled through backward the frame position
Package, and abandon all packages of the 1st B frame found；If B frame packages can not be found, the P frames that discarding the 1st is found
All packages；If can not still find, the package in previous GOP since queue is traveled through forward the frame position is abandoned
1st all packages of B frames for finding；If B frame packages can not be found, all packages of the 1st P frame found are abandoned.If
The P frames that the package of discarding belongs in H.264 code set GOP, then temporarily retain this P frame, team traveled through backward since the frame position
The package in same GOP in row, and abandon all packages of the 1st B frame found；If B frame packages can not be found, from
The frame position starts to travel through forward the package in the same GOP in queue, abandons all packages of the 1st B frame found；If
It can not still find, abandon all packages of current P frames；If current package belongs to B frames, all packages of the frame are directly abandoned.
H.264GOP the priority of middle frame is followed successively by I frames, P frames, B frames, i.e. packet loss strategy two always using excellent from high to low
The minimum frame of first level substitutes the high frame of priority.The idiographic flow of packet loss strategy two is as shown in Figure 2.
Preferably, this method can be by setting suitable parameters α come team's head frame losing scope of control algolithm.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understand, can carry out a variety of equivalent changes to these embodiments without departing from the principles and spirit of the present invention
Change, change, replace and modification, the scope of the present invention is limited by appended claims and its equivalency range.
