Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Fig. 2 is the flow diagram of the data transmission method of the embodiment of the present invention, as shown in Fig. 2, the transmission side data
Method includes the following steps：
Step 201：Three dimensional video data is obtained, the three dimensional video data includes two-dimensional video data and depth data.
Here, three dimensional video data is obtained by terminal, terminal here can be mobile whole such as mobile phone, tablet computer
End, can also be the terminal of the types such as computer.Terminal obtain three dimensional video data mode can with but be not limited to following several：
Mode one：Terminal acquires three dimensional video data by three-dimensional camera.
Mode two：Terminal obtains three dimensional video data from being locally stored in module.
Mode three：Terminal downloads three dimensional video data from network.
In the above described manner for one, terminal obtains 3 D video number from the acquisition component at least capableing of sampling depth information
According to.Specifically, since the acquisition component for capableing of sampling depth information is relatively expensive, terminal does not have three dimensional video data
Acquisition function, but three dimensional video data is acquired by the acquisition component independently of terminal, then passes through acquisition component and terminal
In communication component establish communication link so that terminal obtain acquisition component acquisition three dimensional video data.Wherein, the acquisition
Component can specifically be realized by least one of：When depth camera, binocular camera, 3D structure lights camera module, flight
Between (TOF, Time Of Flight) camera module.
As another embodiment, terminal itself has the acquisition function of three dimensional video data, it will be understood that terminal is set
It is equipped with the acquisition component at least capableing of sampling depth information, such as is provided with at least one lower component：Depth camera, binocular
Camera, 3D structure lights camera module, TOF camera modules, to acquire three dimensional video data.
Wherein, the three dimensional video data of acquisition includes two-dimensional video data and depth data；The two-dimensional video data is used
In characterization flat image, such as it can be RGB data；Depth data characterize the targeted acquisition target of acquisition component surface with
The distance between acquisition component.
Step 202：It determines the two-dimensional video data corresponding first access channel, and determines the depth data pair
The the second access channel answered.
After terminal obtains three dimensional video data, there is demand that the three dimensional video data is transferred to other-end, to realize
The three dimensional video data is presented on other-end.Such as the scene of video conference, scene of live streaming etc., it is required in real time
The three dimensional video data that local terminal is got is transferred to other one or more terminals by ground.
For transmitting three dimensional video data between terminal 1 and terminal 2, the transmission path between terminal 1 and terminal 2 is：
Terminal 1 → 1 → MEC1 of access net → (for a user intermediate path is flight data recorder, and user, which is indifferent to, also to be needed not know about
Between path) → MEC2 → 2 → terminal of access net 2.It is synchronous by virtual channel (high-speed channel) between MEC1 and MEC2, thus
Time delay is very low.Here, it is only explained by taking two MEC as an example, when specific implementation, can also there is greater number of MEC
A cluster is formed, the MEC in this cluster forms LAN by virtual velocity tunnel, and the high speed to realize each MEC is same
Step, a MEC can connect multiple terminals, it is seen then that can realize the low-down 3 D video number of time delay by this network architecture
According to transmission.In addition, the physical connection mode between MEC, can specially be connected by private network, the network of lease operator can also be passed through
(framework as shown in Figure 1) is connected by core net, it is also possible to be connected by other approach.It should be understood that above-mentioned MEC refers to
MEC servers.
Based on this, after terminal obtains three dimensional video data, first step transmission is exactly to be transferred to MEC by accessing net.For
It ensures safety of the three dimensional video data in this section of transmission path, needs to the two-dimensional video data and the depth data
It is encrypted respectively；In addition, first identifier information is added in the two-dimensional video data after encryption, and after encryption
Second identifier information is added on the depth data；Wherein, the first identifier information is for identifying the two-dimensional video data
It is carried on first access channel, the second identifier information is carried on second access for identifying the depth data
Channel.
In one example, MD5 algorithms may be used to carry out the two-dimensional video data and the depth data respectively
Encryption, it is not limited to this, encrypted processing can also be realized using other algorithms.
In the embodiment of the present invention, three dimensional video data is divided into two paths of data, respectively：Two-dimensional video data and depth number
According to.Wherein, every frame RGB image needs in two-dimensional video data are aligned with every frame depth image in depth data, a frame RGB
Image corresponds to a frame depth image, in this way, corresponding RGB image and depth image just can finally synthesize correct graphics
Picture.
In the embodiment of the present invention, to the transmission of three dimensional video data particular by two-dimensional video data and depth data
Distribution is transmitted to realize.In view of the access way between terminal and MEC can there are many, and with terminal capabilities
It is constantly promoted, terminal can be communicated by plurality of access modes with MEC simultaneously, such as WiFi access ways, the access sides LTE
Formula, 5G NR access ways, independently arrange net (SA) access way, dependent are arranged net (NSA) access way etc., in an example,
Terminal can support tri- kinds of access ways of LTE, NSA, WiFi simultaneously, and in another example, terminal can support LTE+ simultaneously
Two kinds of access ways of WiFi, in further example, terminal can support two kinds of access ways of SA+WiFi simultaneously.Each access side
Formula has the advantages that respective, such as the network transfer speeds of WiFi access ways are fast, and the bit error rate of LTE access ways is low, safety
Secure, 5G NR access ways have the characteristics that network transfer speeds are fast has the characteristics that the bit error rate is low again.
In the embodiment of the present invention, terminal supports plurality of access modes simultaneous transmission data, in order to accomplish the biography of higher efficiency
Defeated three dimensional video data, it is thus necessary to determine that two-dimensional video data corresponding first access channel, and determine the depth number
Channel is accessed according to corresponding second.In one embodiment, the meet first transmission item is needed based on the two-dimensional video data
Part determines the two-dimensional video data corresponding first access channel；The meet second transmission is needed based on the depth data
Condition determines the depth data corresponding second access channel.Here transmission conditions for example can be time delay, packet loss,
Bit error rate etc..Generally, two-dimensional video data is larger relative to the data volume of depth data, but the importance of depth data compared with
Height, thus the fast access channel of transmission speed may be used to transmit two-dimensional video data, using the secure access of safety
Depth data is transmitted in channel.
In one embodiment, it is contemplated that the state of heterogeneous networks can change, thus can detect each network
Network state parameters (such as network speed, not busy busy condition, congestion level etc.), different networks corresponds to different access channels；Base
In the network state parameters of each network, the first network for meeting first transmission conditions is determined, by first net
The corresponding access channel of network is as the two-dimensional video data corresponding first access channel；Network based on each network
State parameter determines and meets the second network of second transmission conditions, using the corresponding access channel of second network as
Depth data corresponding second access channel.In this way, can be that two-dimensional video data adaptively selects efficiency of transmission
Higher access channel, and adaptively select the higher access channel of efficiency of transmission for depth data.
In said program, the two-dimensional video data needs the first transmission conditions met and the depth data to need
The second transmission conditions to be met can also refer to the type of service belonging to the three dimensional video data, by taking 5G scenes as an example, industry
Service type is roughly divided into following several classes：Enhanced mobile broadband (eMBB, Enhance Mobile Broadband) business, it is low when

Business is analyzed.The typical case of URLLC includes：Industrial automation, power automation, tele-medicine operation, traffic peace
All risk insurance barrier etc..The typical feature of URLLC includes：The insensitive business of high Connection Density, small data quantity, time delay, the low cost of module
With the long life etc..

When accessing channel selecting, selection strategy can be intelligently updated with reference to the record of history, to selecting user satisfaction highest
Access channel, more humanized service is provided.Again for example：MEC can be that terminal issues routing strategy, terminal periodically
Selection access channel is determined how based on the routing strategy, the routing strategy of the sides MEC can be based on but not limit to
It is configured in following a variety of dimensions：The precedence information of APP, network state, the history of terminal access data, terminal.MEC is to each

One access channel, such as：Terminal is after two paths of data selection accesses channel, to record the efficiency of transmission in the access channel (such as every time
Average network speed, average error rate etc.), record user whether can disconnect the behaviour that access channel is switched to other access channels manually
Make, and feed back to MEC or local is recorded, when carrying out access channel selecting again, can come intelligently with reference to the record of history
