First embodiment
Referring to figure 3., Fig. 3 is a kind of stream for wireless bandwidth multi-channel video transmission method that first embodiment of the invention provides
Cheng Tu, the method are applied to wireless device.Process shown in Fig. 3 will be described in detail below, the method includes：
Step S110：Wireless device corresponding to the video data of the road multi-channel video Zhong Mei based on preparatory agreement transmission when
Between, detect whether the transmission opportunity for reaching itself.
It, may if all sending data in the same time when multi-channel video is needed to wireless bandwidth to transmitted data on network
It is inadequate to will cause wireless bandwidth, each road video data may result in network blockage because seizing band, so that multichannel be caused to regard
In frequency certain all the way or a few road videos occur postponing or packet loss, lead to the inaccuracy of data statistics, video data passes
Defeated efficiency is relatively low.
In order to avoid the above problem, in the present embodiment, corresponding to the road multi-channel video Zhong Mei video data to be sent
Wireless device (such as WIFI equipment) before transmitting data, can based on preparatory agreement determine sending time, detection
Whether the transmission opportunity of this equipment is reached.
Wherein, the equipment is stated in the sending time that the preparatory agreement determines should be when by video data
It is sent.
Certainly, as an alternative embodiment, please referring to Fig. 4, before step S110, the method can also be wrapped
It includes：
Step S101：Wireless device corresponding to the video data of the road multi-channel video Zhong Mei to each other between send radio
Wave, the radio wave include the attribute information of wireless device video data to be sent.
Wherein, the attribute information may include：Size of data corresponding with the video data and when estimating transmission
Between.
Assuming that wireless network is WIFI network, assisted automatically then WIFI signaling can be first passed through between each wireless device in advance
Quotient's bandwidth occupancy situation informs the size of data to be sent of itself each other and needs that bandwidth resources how long occupied.
Step S102：The multiple radio waves for obtaining the transmission of other wireless devices, obtain multiple attribute informations.
Step S103：Based on the multiple attribute information, obtained with other wireless device agreements corresponding with this wireless device
Video data sending time.
Each wireless device can do time sharing transmissions strategy based on the multiple attribute informations received in WIFI bandwidth, determine
Each wireless device should carry out data transmission at time point at which, guarantee that every road video frequency channel can be according to maximum output
Efficiency does data transmission in bandwidth.
After step silo, step S120 is executed.
Step S120：When to be no, the transmission opportunity for whether reaching itself continued to test.
It detects when being no, illustrates not up to itself transmission opportunity itself, then machine examination when wireless device continues
It surveys.
Step S130：When to be, to the corresponding video data of wireless network transmissions.
When detecting to be, illustrate the transmission opportunity for reaching itself, wireless device is by corresponding video data transmission to nothing
On gauze network, at this time since video data only corresponding with wireless device carries out data transmission on wireless bandwidth, other views
Frequency according in etc. state to be passed, it means that the road video data can exclusively enjoy network bandwidth whithin a period of time, entire to negotiate
Process is Millisecond, sends the shadow without generating network delay to video data in the case where WIFI network bandwidth is sufficient
Ring, can also reduce because bandwidth is seized and caused by WIFI network congestion, substantially increase video data transmission efficiency, it is right
The utilization rate of WIFI bandwidth also significantly improves.
As shown in figure 5, Fig. 5 is the schematic diagram of multi-channel video time sharing transmissions strategy.
However, as shown in fig. 6, WIFI network may be because that network fluctuation occurs in environmental factor or bandwidth is insufficient.At this point,
In order to improve network data transmission efficiency, the code rate of each road video can be adjusted.But due to the fluctuation of wireless network
Usually bigger than cable network and no regularity, this can directly result in the inaccuracy of data statistics, so that video code rate
Adjustment would generally lag, this just loses the practical significance of adjustment.
In order to solve this problem, optionally, Fig. 7 is please referred to, after step s 130, the method can also include：
Step S140：It when detecting that network fluctuation occurs in the wireless network, is communicated, is assisted with other wireless devices
Quotient generates neural network forecast result.
Wireless device can detect the video data transmitted in wireless bandwidth, once discovery video data occurs
Packet loss then illustrates that wireless network occurs the situation of network fluctuation or bandwidth deficiency because of environmental factor.At this point, wireless device can be with
It is communicated with other wireless devices, the testing result based on other wireless devices, negotiates to generate neural network forecast as a result, so as to nothing
Line equipment can be based on neural network forecast as a result, when sending data next time, carry out dynamic regulation to video data.
Optionally, wireless device can also judge the bandwidth situation of wireless network according to the network signal of wireless network.
Step S150：Based on the neural network forecast as a result, the view of dynamic regulation video data corresponding with this wireless device
Frequency code rate.
When wireless device detects that wireless network signal dies down, the view of video data corresponding with this wireless device is lowered
Frequency code rate；
When the neural network forecast result characterizes the wireless network signal and becomes strong, view corresponding with this wireless device is raised
The video code rate of frequency evidence.
Optionally, the wireless network signal is characterized in the neural network forecast result and become strong, and continue in this case
When the data of preset times are all normally sent, the video code rate of video data corresponding with this wireless device is raised.
