Fig. 1 shows a kind of schematic flow sheet of the control method of the data is activation according to the application one side；The side Method includes repeat step S11~step S14：

Step S11, packet is respectively processed into by acquired director data, voice data, video data, correspondence It is put into instruction queue, audio queue and video queue；Here, four queues of initialization：Instruction queue is (in the examples below Control instruction queue and instruction queue are alternatively used), audio queue and video queue and a transmission data statistics queue. When video calling at first, capture user desktop or camera simultaneously be compressed into packet, added in video queue； Current voice data and compressed encoding can be also obtained from sound card simultaneously, the packet after compressed encoding is then added to sound In frequency queue, the operation of all users and control instruction can all be packaged into packet and be stored in instruction queue.

Step S12, judges to whether there is packet to be sent in the instruction queue, if so, then sending described pending The packet for sending, and the current weighted average network bandwidth is calculated after being sent completely；In the embodiment of the present application, in initialization When stating four queues, can also start a data is activation thread, dedicated for sending instruction, packets of audio data and video data Bag, whether the thread is first looked in control instruction queue has the packet to send, if not then checks audio queue, if Have and just call transmission function (Send TcpMesg functions) all to send the packet in all of control instruction queue.Send The major function of TcpMesg functions is to send the data to other equipment, while also to be carried out to current network transmission bandwidth Assessment, after the completion of calling the function to send the packet within, is estimated to current network transmission bandwidth, obtains current adding The weight average network bandwidth.

Step S13, judges to whether there is packets of audio data to be sent in the audio queue, if so, then relatively more described The current weighted average network bandwidth and preset audio bandwidth threshold, obtain comparative result, select corresponding according to comparative result Audio delivery plan sends the packets of audio data to be sent, and current weighted average is recalculated after being sent completely The network bandwidth；In embodiments herein, whether there is packet to send in inspection audio queue, skipped if not, If then first calling voice data to send function (CouldSendAudioNow functions) audio number can be sent to check whether According to bag, the function can be according to current network state, the weighted average network bandwidth and preset audio bandwidth threshold that will be current It is compared, obtains comparative result, corresponding audio delivery plan is selected by the audio number to be sent according to comparative result Sent according to bag, such as selection does not send or continuously transmits audio delivery plan, and current adding is recalculated after being sent completely The weight average network bandwidth.

In step S14, judge to whether there is video data bag to be sent in the video queue, if so, then comparing The current weighted average network bandwidth and default video bandwidth threshold value, obtain comparative result, select corresponding according to comparative result Video delivery plan sends the video data bag to be sent, and current weighted average is recalculated after being sent completely The network bandwidth.In the embodiment of the present application, determine in audio queue in the absence of after the packets of audio data for needing to send, it is necessary to check Whether having video data bag in video queue needs to send, if directly skipped without if, if video data bag will send, Then first calling video data to send function (CouldSendVideoNow functions) can send video data bag to check whether, The detailed process of inspection is that the current weighted average network bandwidth is compared with default video bandwidth threshold value, obtains comparing knot Really, corresponding video delivery plan is selected to send the video data bag to be sent according to comparative result.

Fig. 2 shows the transmission priority of change control instruction, voice data and video data in the embodiment of the application one Schematic flow sheet.First, log-on data sends thread, judges whether network connection is normal in the case where program is not exited, such as It is really abnormal to need to reconnect, judge whether control instruction queue has data to send in the case of network connection is normal, If so, then calling SendTcpMesg functions to send data, and calculating network bandwidth again；If it is not, then audio data queue Whether have data to send, if so, then calling CouldSendVideoNow functions, voice data can be sent checking whether, Whether the function returns to a value iRetValue according to current network state, the return value is judged more than 0, if so, then taking sound First bag data of frequency data queue, calls SendTcpMesg functions to send function, and calculating network bandwidth again；Work as audio , it is necessary to whether have data to send in judging video data queue when there is no the data to be sent in data queue, if so, then taking First bag data of video data queue, calling CouldSendVideoNow functions checking whether can send video data, Return value iRetValue2 is determined according to current network state, whether the return value is judged more than 0, if it is not, then abandoning this Bag data, if so, then call SendTcpMesg functions to send function, and calculating network bandwidth again, to this transmission cycle Complete, whether program returns thread and start to check again for have the control instruction need to send.The control of data is activation described above Method processed is preferably applied to video conference, using according to different network states, changes control instruction, voice data and video counts According to transmission priority, it is to avoid the mode of image quality and resolution ratio is reduced because taking to reduce the video caused by the demand of bandwidth Ambiguous problem.

It should be noted that whether being judged the return value of only the application in above-described embodiment more than 0 with return value One citing of threshold value, it is also possible to be set to other values, other return value threshold values that are existing or being likely to occur from now on can such as be fitted For the application, should also be included within the application protection domain, and be incorporated herein by reference herein.

With continued reference to Fig. 2, calculating network bandwidth is to assess current network state, by calculating current weighted average The network bandwidth realizes that detailed process is：Transmission information according to a transmitted recently packet determines currently transmitted speed, And the transmission information of a nearest packet is recorded in queue is counted, wherein, the transmission information includes transmitted One length of packet and transmission time；Transmitted by the transmission information of the packet in statistics queue is calculated respectively Nearest n packet the first average transmission rate, the second average transmission rate, the institute of transmitted nearest m data bag 3rd average transmission rate of the nearest w packet for sending, wherein, n, m and w are positive integer, and n>m>w；Described will work as Preceding transmission rate, the first average transmission rate, the second average transmission rate and the 3rd average transmission rate are entered Row weighted average, obtains the weighted average network bandwidth.

Here, the length and transmission time according to a transmitted recently packet obtain currently transmitted speed, and Before the transmission information of a nearest packet is recorded in statistics queue, including：Judge whether transmitted packet is sent out Send successfully, if it is not, then closing network connection, empty the transmission information in statistics queue.

In the embodiment of the application one, after a packet has been sent, according to the length and consuming that send packet Time can calculate currently transmitted speed framerate1；Meanwhile, it is described to record the packet in queue is counted Transmission information, including：By the length of transmitted packet and the end of transmission time press-in statistics queue；Judge described Whether the transmission information number of the packet recorded in statistics queue exceedes default threshold value, if so, then will be pre- more than described If threshold value corresponding to the transmission information of the packet of earliest preservation deleted.Here, length and time will be sent The end of statistics queue is pressed onto, statistics queue only preserves the value of nearest 300 bag data, if it exceeds just deleting earliest data Remove.It should be noted that nearest 300 bag is a citing of default threshold value, other numerical value are may be alternatively provided as.

Then, the data of the traversal statistics all records of queue, count the average transmission rate of nearest 300 bag data respectively Framerate2, the average transmission rate framerate3 of nearest 30 bag data, the average transmission rate of nearest 10 bag data Framerater4, then calculates the weighted average network bandwidth according to following formula：

The weighted average network bandwidth=weight 1*framerate1+ weight 2*framerate2+ weights 3*framerate3+ Weight 4*framerate4,

The weighted average network bandwidth is the core data of whole network data is activation speed control, and specific flow chart is such as Shown in Fig. 3：Call SendTcpMesg to send data, if sending failure, close network connection and empty statistics queue, return It is worth for -1；If sending successfully, according to transmission data length and transmission Time Calculation this bag data transmission rate framerate1, Then, whether the length and transmission time for this being sent put statistics queue tail into, judge the length for counting queue more than 10 Bag, if it is not, 1 is then returned, if so, whether then judge to count the length of queue more than 300 bags, if so, then by statistics queue most An early bag statistics is deleted, and when of length no more than 300 bag counted in counting queue, is calculated according to statistics queue respectively The average transmission rate framerate2 of nearest 300 bag, then directly acquiescence is entered as less than 300 bag datas by framerate2 Value, here, what the Mean Speed that default value can count all of statistics bag of queue according to determined, such as only 200 bags Data, then calculate the average transmission rate of 200 bags；The average transmission rate of nearest 100 bag is calculated according to statistics queue Framerate3, then directly default value is entered as less than 100 bag datas by framerate3；Nearest 10 are calculated according to statistics queue Bag average transmission rate framerate4, framerate4 is directly then entered as default value less than 10 bag datas, according to Each average transmission rate and respective weight of upper calculating are weighted the calculating of averaging network bandwidth.

In step S13, judge to whether there is packets of audio data to be sent in the audio queue, if so, then compare working as Whether the preceding weighted average network bandwidth is more than the first preset audio bandwidth threshold；If being less than or equal to, corresponding audio is selected Delivery plan is not send the packets of audio data to be sent, and the packets of audio data is taken from the audio queue Go out；If being more than, the scope selection of the preset audio bandwidth threshold according to where the current weighted average network bandwidth is right The audio delivery plan answered sends the packets of audio data to be sent.

In the embodiment of the application one, as shown in Fig. 2 being needed according to current network-like when packets of audio data is transmitted State selects the scheme that corresponding audio sends to send packets of audio data to be sent, by relatively more current weighted average Netowrk tape Wide and the first preset audio bandwidth threshold, determines a return value, and the value is if less than 0 or equal to 0, then it represents that can not send number According to, then directly the data of taking-up are abandoned, if the value is more than 0, then it represents that the number of the packets of audio data that can be continuously transmitted, Several packets of audio data are so continuously transmitted according to the return value.

When return value is more than 0, the scope of the preset audio bandwidth threshold according to where the current weighted average network bandwidth Corresponding audio delivery plan is selected to send the packets of audio data to be sent, in step s 13, current weighted average net The scope of the preset audio bandwidth threshold where network bandwidth is the bandwidth range of any one appearance in step S131~step S133, Wherein, step S131, if the scope of the preset audio bandwidth threshold where the current weighted average network bandwidth be more than Equal to the second audio pre-set bandwidths threshold value, then it is that audio sample parameter is set to a width of to select corresponding audio delivery plan The binary channels of the first sampled value, the packets of audio data is sent according to the audio sample parameter.Step S132, if described current The weighted average network bandwidth where the scope of preset audio bandwidth threshold be less than the second preset audio bandwidth threshold and big It is that audio sample parameter is set to bandwidth in corresponding audio delivery plan equal to the 3rd preset audio bandwidth threshold, is then selected It is the binary channels of the second sampled value, the packets of audio data is sent according to the audio sample continuous parameters.Step S133, if institute The scope of the preset audio bandwidth threshold where stating the current weighted average network bandwidth is less than the 3rd preset audio bandwidth threshold And more than or equal to the first preset audio bandwidth threshold, then it is to be set to audio sample parameter to select corresponding audio delivery plan Single channel with a width of 3rd sampled value, the packets of audio data is sent according to the audio sample continuous parameters.

In the embodiment of the application one, the current network state of basis as shown in Figure 4 selects corresponding audio sender The flow chart of case, will first call CouldSendAudioNow functions to determine the speed of transmission speed before sending voice data And adjustment audio sample parameter adapts to the network bandwidth.Due to a width of 196KB/s of band that the sampling parameter of system default needs； When the weighted average network bandwidth is more than 196KB/s, voice data can just be sent with maximal rate；When the network bandwidth is less than 196KB/s and it is accomplished by for the sample frequency of audio being reduced to 16K when more than 48KB/s, can so ensures that audio is smooth While also for transmission of video leaves appropriate bandwidth；When the network bandwidth is less than 48KB/s and when more than 8KB/s, just need The sample frequency of audio is reduced to 8K, and using single channel sampling, can so ensure that audio is smooth under extremely low bandwidth； When bandwidth further declines, then audio transmission is temporarily interrupted, the transmission of control instruction is ensured with all strength.It should be noted that on The first preset audio bandwidth threshold is 8KB/s in stating embodiment, and the second preset audio bandwidth threshold is 196KB/s, and the 3rd presets Audio bandwidth threshold value is 48KB/s, and each preset audio bandwidth threshold is only for example, other it is existing or be likely to occur from now on it is each Preset audio bandwidth threshold is such as applicable to the application, should also be included within the application protection domain, and herein with reference side Formula is incorporated herein.

In step S14, judge to whether there is video data bag to be sent in the video queue, if so, then compare working as Whether the preceding weighted average network bandwidth is more than the first default video bandwidth threshold value；If being less than or equal to, corresponding video is selected Delivery plan is not send the video data bag to be sent, and the video data bag is taken from the video queue Go out；If being more than, the scope selection of the default video bandwidth threshold value according to where the current weighted average network bandwidth is right The video delivery plan answered sends the video data bag to be sent.

In the another embodiment of the application, as shown in Fig. 2 being needed according to current network when video data bag is transmitted The scheme that the corresponding video of condition selecting sends sends video data bag to be sent, by relatively more current weighted average network Bandwidth and the first default video bandwidth threshold value, determine a return value, and the value is if less than 0 or equal to 0, then it represents that abandon this bag Data are not transmitted, if the value is more than 0, call SendTcpMesg to send this bag data.

When return value is more than 0, the scope of the default video bandwidth threshold value according to where the current weighted average network bandwidth Corresponding video delivery plan is selected to send the video data bag to be sent, in step S14, current weighted average net The scope of the default video bandwidth threshold value where network bandwidth is the bandwidth range of any one appearance in step S141~step S145, Wherein, step S141, if the scope of the default video bandwidth threshold value where the current weighted average network bandwidth be more than Equal to the second default video bandwidth threshold value, then it is continuously to be sent out with current maximum speed to select corresponding video delivery plan Send the video data bag to be sent.Step S142, the pre- setting video where the current weighted average network bandwidth The scope of bandwidth threshold is selection when video bandwidth threshold value is preset less than second and video bandwidth threshold value is preset more than or equal to the 3rd Corresponding video delivery plan is to judge whether current video data bag to be sent is key frame, if so, then sending described working as Preceding video data bag to be sent, if it is not, then being sent when the frame number cached in the video queue is less than or equal to default frame number The current video data bag to be sent；If current video data bag to be sent is for non-key frame or when the video queue When the frame number of middle caching is more than default frame number, then the current packet to be sent is abandoned.Step S143, when described current The scope of the default video bandwidth threshold value where the weighted average network bandwidth is less than the 3rd default video bandwidth threshold value and is more than During equal to the 4th default video bandwidth threshold value, it is to judge current video data bag to be sent to select corresponding video delivery plan Whether it is key frame, if it is not, the current video data bag to be sent is then sent, if so, then abandoning described current to be sent Packet.Step S144, when the scope of the default video bandwidth threshold value where the current weighted average network bandwidth is When less than the 4th default video bandwidth threshold value and presetting video bandwidth threshold value more than or equal to the 5th, corresponding video sender is selected Case is to judge whether current video data bag to be sent is key frame, if so, the time that then judging distance previous frame sends is It is no more than the first preset time threshold, if so, then sending the current video data bag to be sent；If currently to be sent regard Frequency packet be time for sending of non-key frame or judging distance previous frame not less than the first preset time threshold, then abandon described Current packet to be sent.Step S145, the default video bandwidth threshold where the current weighted average network bandwidth The scope of value is when video bandwidth threshold value is preset less than the 5th and video bandwidth threshold value is preset more than or equal to the 6th, to select corresponding Video delivery plan is to judge whether current video data bag to be sent is key frame, if so, then judging distance previous frame hair Whether the time sent is more than the second preset time threshold, if so, then sending the current video data bag to be sent；If current Video data bag to be sent be time for sending of non-key frame or judging distance previous frame not less than the second preset time threshold, Then abandon the current packet to be sent.

In the embodiment of the application one, the current network state of basis as shown in Figure 5 selects corresponding video sender The schematic flow sheet of case, CouldSendVideoNow functions will be first called before video data bag is sent, and the function is according to adding The weight average network bandwidth come determine whether send this bag data.Consideration based on compression algorithm and user's screen resolution, System default needs the bandwidth of 1MB/s；When the weighted average network bandwidth is more than 1MB/s, video data just can be with maximum speed Degree sends；When the weighted average network bandwidth is less than 1MB/s and during more than 300KB/s, then need to abandon partial video data, if Current data are that key frame can then send, if non-key frame, then according to outgoing data bag in video data queue Quantity is determined, and can be sent if the data for buffering are less, and current data must be abandoned if more, for example, judge Whether the frame number cached in video data queue is more than default frame number 10, if it is not, can then send data；When weighted average network Bandwidth can only send key frame less than 300KB/s and during more than 196KB/s, and other all non-key frames are all abandoned；When plus The weight average network bandwidth then sends a key in 3 seconds less than 196KB/s and during more than 48KB/s every the first preset time threshold Frame, and other data are all abandoned；It is when the weighted average network bandwidth is less than 48KB/s and during more than 16KB/s, then pre- every second If time threshold sends a key frame for 10 seconds, and other data are all abandoned；When bandwidth further declines, then temporarily interrupt Transmission of video, ensures the transmission of control instruction and voice data with all strength.It should be noted that the Key-Frame in Fig. 5 is key Frame, in above-described embodiment, the first default video bandwidth threshold value is 16KB/s, and the second default video bandwidth threshold value is 1MB/s, the 3rd Default video bandwidth threshold value is 300KB/s, and the 4th default video bandwidth threshold value is 196KB/s, the 5th default video bandwidth threshold value It is 48KB/s, each default video bandwidth threshold value is only for example, other each default video bandwidths that are existing or being likely to occur from now on Threshold value is such as applicable to the application, should also be included within the application protection domain, and is incorporated herein by reference herein.

In sum, by the control method of data is activation described herein, using according to heterogeneous networks state, change The transmission priority of control instruction, voice data and video data, will when priority cannot ensure transmission of video when adjusting The automatic frame per second for reducing video, ensures the control mode of control instruction stream and audio stream as far as possible；As user bandwidth continues to reduce, Guarantee audio is smooth under the modes such as the sample frequency of audio bandwidth as small as possible can be reduced.
