Based on the above-mentioned characteristic of view networking, one of core idea of the application is proposed, it then follows the agreement for regarding networking, at this
In application, compared to transmitting each first view networked video data packet, network video data to be transmitted of view is split multiple the
One view networked video data packet；To the first more than every two in multiple first view networked video data packets view networked video number
XOR operation is carried out respectively according to packet, obtains multiple second view networked video data packets；Multiple second view networked videos are sent respectively
At least first view networked video data packet in data packet and the multiple first views networked video data packets of transmission, can increase biography
The redundancy of defeated view networked video data packet even if the first a small number of view networked video data-bag losts, but passes through other
Second is still able to restore each first view networked video data packet depending on networked video data packet, so as to avoid opposite end
The the first view networked video data received are imperfect, so as to avoid opposite end meeting when broadcasting first regards networked video data
There is Huaping phenomenon, and then avoids reducing user experience.
Referring to Fig. 5, a kind of step flow chart of video data transmitting method based on view networking of the application is shown, it should
Method may include steps of:
In step s101, view networking video data to be transmitted is split into multiple first views networked video data packets；

Net video data packet separately constitutes data packet group, then for any one data packet group, to two in the data packet group
One view networked video data packet carries out XOR operation, obtains first second view networked video data packet, then every for other
One data packet group, equally execution aforesaid operations, to obtain multiple second view networked video data packets.
However, in the aforementioned embodiment, the second obtained view networked video data packet is more, and data redudancy is higher,
Transmission second is depending on that can occupy more Internet resources and reduce efficiency of transmission when networked video data packet.
Therefore, it can determine and tear open in another embodiment of the application to save Internet resources and improve efficiency of transmission
First quantity of the first view networked video data packet got；Obtain default distribution function；According to default distribution function and
First view networked video data needed for the acquisition of one quantity obtains each second view networked video data packet by XOR operation
Second quantity of packet；To the first more than every second quantity in multiple first view networked video data packets view networked video data
Packet carries out XOR operation respectively, obtains multiple second view networked video data packets.
In step s 103, multiple second view networked video data packets are sent respectively and send multiple first view networking views
At least first view networked video data packet in frequency data packet.
In obtained multiple second views networked video data packets, some second depending on networked video data packet are by two the
One, which carries out XOR operation depending on networked video data packet, obtains, some second view networked video data packets are by three first views connection
Net video data packet carries out XOR operation and obtains, some second view networked video data packets are joined by the first view greater than three
Net video data packet packet carries out what XOR operation obtained.
If what is sent to opposite end is all the second view networked video data packet, the second view networking is regarded based on the received for opposite end
Frequency data packet can not often restore each first view networked video data packet.Therefore, it is also desirable to send at least one to opposite end
It is a first view networked video data packet packet so that opposite end can according to this at least one first view networked video data packet multiple
Second depending on restoring each first view networked video data packet in networked video data packet.
Under normal conditions, if second depending on networked video data packet be carried out by two first view networked video data packets it is different
Or operation obtains, as long as then knowing any one first view networked video data in two first view networked video data packets
Packet, can be from second depending on restoring another first view networked video data packet in networked video data packet.
If second is to carry out XOR operation depending on networked video data packet by three first to obtain depending on networked video data packet
, it, can be from as long as then knowing that any two first in two first view networked video data packets regard networked video data packets
Second depending on restoring another first view networked video data packet in networked video data packet.
That is, if second depending on networked video data packet be by least two first view networked video data packets carry out exclusive or
What operation obtained, then need to know that at least two first regard the quantity in networked video data packet subtracts one as at least two first
It, could be from second depending on restoring another first view networked video data packet in networked video data packet depending on networked video data packet.
In order to save bandwidth, need to reduce to the greatest extent the quantity of the first view networked video data packet of transmission, therefore sending
It is multiple first view networked video data packets at least first view networked video data packet when, can it is multiple second view networking view
In frequency data packet, determines and carry out the second view networked video number obtained from XOR operation as two first view networked video data packets
According to packet；Determine two first view networked video numbers of the second view networked video data packet determined by XOR operation
According to packet；Select one first view networked video data packet in two first determined view networked video data packets；Send choosing
The the first view networked video data packet selected.
Wherein, in order to determining to be carried out second obtained from XOR operation as two first view networked video data packets
Depending on networked video data packet, in this application, to more than the every two in multiple first view networked video data packets first
XOR operation is carried out respectively depending on networked video data packet, after obtaining multiple second view networked video data packets, for what is obtained
Any one second view networked video data packet, by this second depending on networked video data packet and by XOR operation obtain this
At least two first view networked video data packet groups of two view networked video data packets are stored in the second view connection at corresponding table item
In corresponding relationship between net video data packet and the first view networked video data packet.For other obtained each second views
Networked video data packet, equally execution aforesaid operations.
In this way, when it needs to be determined that two of the second view networked video data packet determined by XOR operation the
When one view networked video data packet, pair between networked video data packet can be regarded in the second view networked video data packet and first
In should being related to, two first views networked video data packet corresponding with the second view networked video data packet is searched.
In this application, compared to each first view networked video data packet is transmitted, by view networking video counts to be transmitted
Networked video data packets are regarded according to splitting multiple first；To more than the every two in multiple first view networked video data packets first
XOR operation is carried out respectively depending on networked video data packet, obtains multiple second view networked video data packets；Multiple are sent respectively
At least first view networked video data in two view networked video data packets and the multiple first views networked video data packets of transmission
Packet, can increase the redundancy of the view networked video data packet of transmission, even if the first a small number of view networked video data-bag losts,
But second it is still able to restore each first view networked video data packet depending on networked video data packet by other, thus
The the first view networked video data that can be received to avoid opposite end are imperfect, network so as to avoid opposite end from regarding in broadcasting first
It will appear Huaping phenomenon when video data, and then avoid reducing user experience.
