For a better understanding of embodiments of the present invention, the following description of the video networking is presented to one skilled in the art:
the partial techniques applied by the video networking are as follows:
network technology (network technology)
The network technology innovation of the internet of vision improves on the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Unlike pure network Packet Switching (Packet Switching) or network circuit Switching (Circuit Switching), the technology of video networking employs Packet Switching to meet Streaming requirements. The video networking technology has the flexibility, simplicity and low price of packet switching, and simultaneously has the quality and the safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.
Exchange technology (Switching Technology)
The video network adopts the two advantages of the asynchronization and the packet switching of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, has full-network end-to-end seamless connection, and is directly connected with the user terminal to directly bear the IP data packet. The user data does not need any format conversion in the whole network. The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.
Server technology (Server Technology)
The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.
Accumulator technology (Storage Technology)
The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system for adapting to the ultra-large capacity and ultra-large flow media content, the program information in the server instruction is mapped to a specific hard disk space, the media content does not pass through the server any more, the media content is instantly and directly delivered to a user terminal, and the waiting time of the user is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.

The structural design of the video networking thoroughly structurally solves the network security problem puzzling the Internet by means of independent permission of each service, complete isolation of equipment and user data and the like, generally does not need antivirus programs or firewalls, eliminates attacks of hackers and viruses, and provides a structural carefree security network for users.
Service innovation technology (Service Innovation Technology)
The unified video platform fuses services with transmissions, whether a single user, private network users or a network aggregate, but automatically connects at a time. The user terminal, the set top box or the PC is directly connected to the unified video platform, so that various multimedia video services are obtained. The unified video platform adopts a menu type table allocation mode to replace the traditional complex application programming, and can realize complex application by using very few codes, thereby realizing 'infinite' new business innovation.
Networking of the video networking is as follows:
the video networking is a centrally controlled network structure, which may be of the tree network, star network, ring network, etc., but on the basis of this there is a need for a centralized control node in the network to control the whole network.
As shown in fig. 1, the view network is divided into an access network and a metropolitan area network.
The devices of the access network part can be mainly divided into 3 classes: node server, access switch, terminal (including various set-top boxes, code boards, memories, etc.). The node server is connected with an access switch, which can be connected with a plurality of terminals and can be connected with an Ethernet.
The node server is a node with a centralized control function in the access network, and can control the access switch and the terminal. The node server may be directly connected to the access switch or may be directly connected to the terminal.
Similarly, devices of the metropolitan area network portion can also be classified into 3 categories: metropolitan area server, node switch, node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.
The node server is the node server of the access network part, namely the node server belongs to the access network part and also belongs to the metropolitan area network part.
The metropolitan area server is a node with centralized control function in the metropolitan area network, and can control a node switch and a node server. The metropolitan area server may be directly connected to the node switch or directly connected to the node server.
Thus, the whole video network is a hierarchical centralized control network structure, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star, ring and the like.
The access network part can be vividly called as a unified video platform (part in a dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform can be interconnected and intercommunicated through metropolitan area and wide area video networking.

2. View networking data packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), source Address (SA), reserved bytes, payload (PDU), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
| DA | SA | Reserved | Payload | CRC |
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), 256 possibilities are at most provided, the second byte to the sixth byte are metropolitan area network addresses, and the seventh and eighth bytes are access network addresses;
the Source Address (SA) is also composed of 8 bytes (bytes), defined identically to the Destination Address (DA);
the reserved bytes consist of 2 bytes;
the payload portion has different lengths according to the types of the different datagrams, and is 64 bytes if it is various protocol packets, and 32+1024=1056 bytes if it is a unicast packet, and is of course not limited to the above 2 types;
The CRC consists of 4 bytes and its calculation method follows the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of the metropolitan area network is a pattern, there may be 2 or even more than 2 connections between two devices, i.e. there may be more than 2 connections between node switches and node servers, node switches and node switches, node switches and node servers. However, the metropolitan area network address of the metropolitan area network device is unique, and in order to accurately describe the connection relationship between metropolitan area network devices, parameters are introduced in the embodiment of the present invention: a tag to uniquely describe a metropolitan area network device.
The definition of label in this specification is similar to that of MPLS (Multi-Protocol Label Switch, multiprotocol label switching), and assuming that there are two connections between device a and device B, there are 2 labels for packets from device a to device B and 2 labels for packets from device B to device a. The label is split into label and label out, and assuming that the label (in label) of the packet entering the device a is 0x0000, the label (out label) of the packet when leaving the device a may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, that is, the address allocation and label allocation of the metropolitan area network are all led by the metropolitan area server, the node switch and the node server are all passively executed, which is different from the label allocation of the MPLS, which is the result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metropolitan area network mainly includes the following parts:
| DA | SA | Reserved | label (Label) | Payload | CRC |
I.e. Destination Address (DA), source Address (SA), reserved bytes (Reserved), labels, payload (PDU), CRC. Wherein the format of the tag may be defined with reference to the following: the tag is 32 bits, with the high 16bit reservation, with only the low 16bit, and its position is between the reserved bytes and payload of the packet.
Referring to fig. 5, a flowchart illustrating steps of a panoramic video processing method according to an embodiment of the present invention may be applied to a conference management server, which may be a server located in a view networking, and may manage a view networking-based video conference.
Specifically, the method comprises the following steps:
step 501, creating a video conference for a plurality of participant terminals, and determining a panoramic participant terminal supporting panoramic video playing from the plurality of participant terminals;
the panoramic video is a video shot by a 3D camera in 360 degrees in all directions, and a user can randomly adjust the video to watch up, down, left and right when watching the video.
As an example, the plurality of participant terminals may be video networking terminals, and the panoramic participant terminal may be a video networking terminal supporting panoramic video playback.
In practical application, a user can input terminal identifiers of a plurality of participant terminals, such as video network terminal numbers, through a conference management client, so that a video conference aiming at the plurality of participant terminals can be created, and a conference joining request can be initiated by each participant terminal, so that the user joins in the video conference.
Because the panoramic video playing is not supported by some of the participant terminals, if the panoramic video is directly scheduled to the participant terminals, which leads to a compatibility problem, the conference management server can judge whether the participant terminals support the panoramic video playing, and further determine the panoramic participant terminals supporting the panoramic video playing from a plurality of participant terminals so as to perform subsequent panoramic video scheduling.
the first participant terminal can be provided with at least a first network adapter and a second network adapter, can be in communication connection with the panoramic camera by adopting the first network adapter, can be in a direct connection mode, and can be in communication connection with the conference management server by adopting the second network adapter.
After the panoramic video is acquired, the panoramic camera can generate a first video data packet corresponding to the panoramic video, and then the first video data packet can be sent to a first participant terminal, the first participant terminal can receive the first video data packet by adopting a first network adapter, and then the first data packet can be sent to a conference management server by adopting a second network adapter.
For example, when the first participant terminal is a view networking terminal, as shown in fig. 6, the view networking terminal may have one end connected to the panoramic camera and the other end connected to the conference management server through the view networking, so as to access the panoramic video to the view networking, so that all devices in the view networking can watch the panoramic video, and the transmission delay and the katon of the panoramic video can be reduced.
after receiving the first video data packet, it may be determined whether the first video data packet is a panoramic data packet, and when the first video data packet is a panoramic video data packet, one or more second participant terminals may be determined from among the panoramic participant terminals, e.g., when the first participant terminal is a panoramic participant terminal, the second participant terminals may be other panoramic participant terminals in the panoramic participant terminal except the first participant terminal.
And step 504, dispatching the first video data packet to the one or more second participant terminals.
After determining that the first video data packet is a panoramic video packet and determining a second participant terminal supporting panoramic video playing, the first video data packet can be scheduled to the second participant terminal, i.e. the panoramic video is scheduled to the participant terminal supporting panoramic video playing.
For example, in the view networking, as shown in fig. 7, the panoramic video collected by the panoramic camera may be sent to the meeting management through the view networking, and then the meeting management sends the panoramic video to the panoramic view networking terminal supporting the playing of the panoramic video through the view networking.
In an embodiment of the present invention, the method may further include the steps of:
when the first video data packet is a panoramic video data packet, determining one or more third participant terminals from other participant terminals except the panoramic participant terminal; converting the first video data packet into a second video data packet; and scheduling the second video data packet to the one or more third participant terminals.
Wherein the second video data packet may be a non-panoramic video data packet.
In the case that the first video data packet is a panoramic video data packet, one or more third participant terminals may be determined from other participant terminals except the panoramic participant terminal, for example, when the first participant terminal is a participant terminal that does not support panoramic video playback, the first participant terminal may be removed from other participant terminals that do not support panoramic video playback except the panoramic participant terminal, and the third participant terminal may be obtained.
Because the third participant terminal does not support panoramic video playing, the first video data packet can be converted into the second video data packet, and then the second video data packet can be scheduled to the third participant terminal, namely, the panoramic video is converted into the non-panoramic video, and then the non-panoramic video is scheduled to the participant terminal which does not support panoramic video playing.
In an embodiment of the present invention, the method may further include the steps of:
determining one or more fourth participant terminals from the panoramic participant terminals when the first video data packet is a non-panoramic video data packet; converting the first video data packet into a third video data packet; and scheduling the third video data packet to the one or more fourth participant terminals.
The third video data packet may be a panoramic video data packet.
In the case that the first video data packet is a non-panoramic video data packet, the fourth participant terminal may be determined from among the panoramic participant terminals, e.g., when the first participant terminal is a panoramic participant terminal, the fourth participant terminal may be another panoramic participant terminal in the panoramic participant terminals other than the first participant terminal.
After the fourth participant terminal is determined, the first video data packet can be converted into a third video data packet, and then the third video data packet can be scheduled to the fourth participant terminal, namely, the non-panoramic video is converted into the panoramic video, and then the panoramic video is scheduled to the participant terminal supporting panoramic video playing.
In an embodiment of the present invention, the method may further include the steps of:
determining one or more fifth participant terminals from other participant terminals except the panoramic participant terminal when the first video data packet is a non-panoramic video data packet; and scheduling the first video data packet to the one or more fifth participant terminals.
In the case that the first video data packet is a non-panoramic video data packet, the fifth participant terminal may be determined from other participant terminals except the panoramic participant terminal, for example, when the first participant terminal is a participant terminal that does not support panoramic video playback, the first participant terminal may be removed from other participant terminals that do not support panoramic video playback except the panoramic participant terminal, so as to obtain the fifth participant terminal.
After determining the fifth participant terminal, the first video data packet may be scheduled to the fifth participant terminal, i.e. the non-panoramic video is directly scheduled to the participant terminal that does not support panoramic video playback.
In the embodiment of the invention, the panoramic video is accessed to the video conference by creating the video conference aiming at a plurality of participant terminals, determining the panoramic participant terminal supporting panoramic video playing from the plurality of participant terminals, receiving the first video data packet sent by the first participant terminal, determining one or more second participant terminals from the panoramic participant terminal when the first video data packet is the panoramic video data packet, and then dispatching the first video data packet to one or more second participant terminals.
Referring to fig. 8, a step flow chart of a panoramic video processing method according to an embodiment of the present invention is shown, where the method may be applied to a conference management server, and specifically may include the following steps:
in practical application, a user can input terminal identifiers of a plurality of participant terminals, such as video network terminal numbers, through a conference management client, so that a video conference aiming at the plurality of participant terminals can be created, and a conference joining request can be initiated by each participant terminal, so that the user joins in the video conference.
since the video playing types supported by the participant terminal are known, the participant terminal generates a type notification message according to whether the participant terminal supports panoramic video playing or not and sends the type notification message to the conference management server to inform the participant of the video types supported by the participant terminal.
After receiving the type notification message, the type notification message may be parsed, and from the type notification message, a terminal type identifier for characterizing the video play type supported by the terminal type identifier may be determined.
in a specific implementation, a terminal type identifier of a participant terminal supporting panoramic video playing may be predefined as a preset terminal type identifier, and after determining the terminal type identifier from the type notification message, if the terminal type identifier is the preset terminal type identifier, the participant terminal corresponding to the type notification message may be sent to be marked as a panoramic participant terminal supporting panoramic video playing.
after the panoramic video is acquired, the panoramic camera can generate a first video data packet corresponding to the panoramic video, and then the first video data packet can be sent to a first participant terminal, the first participant terminal can receive the first video data packet by adopting a first network adapter, and then the first data packet can be sent to a conference management server by adopting a second network adapter.
in order to distinguish panoramic video from non-panoramic video, the first participant terminal may add a video data identifier, i.e. a tag video type, to the first video data packet, and then the conference management server may parse the first video data packet, so as to determine the video type identifier.
in practical application, the video type identifier corresponding to the panoramic video may be predefined as a preset video type identifier, and then when the determined video type identifier is the preset video type identifier from the first video data packet, the first video data packet may be determined to be the panoramic video data packet.
when the first video data packet is a panoramic video data packet, one or more second participant terminals may be determined from the panoramic participant terminals, e.g., when the first participant terminal is a panoramic participant terminal, the second participant terminals may be other panoramic participant terminals in the panoramic participant terminal except the first participant terminal.
After determining that the first video data packet is a panoramic video packet and determining a second participant terminal supporting panoramic video playing, the first video data packet can be scheduled to the second participant terminal, i.e. the panoramic video is scheduled to the participant terminal supporting panoramic video playing.

Step 1002, when the first video data packet is a panoramic video data packet, acquiring a preset video type identifier;
in order to distinguish panoramic video from non-panoramic video, a video type identifier corresponding to the panoramic video may be predefined as a preset video type identifier, and then when the first video data packet is a panoramic video data packet, the preset video type identifier is obtained.
After obtaining the preset video type identifier, the first participant terminal can add the preset video data identifier, namely, mark the video type, in the first video data packet, further, repackage the first video data packet, send the repackaged first video data packet to the conference management service, and the conference management server can analyze the first video data packet, further, can determine the video type identifier.
After determining that the first video data packet is a panoramic video packet and determining a second participant terminal supporting panoramic video playing, the conference management server may schedule the first video data packet to the second participant terminal, that is, schedule the panoramic video to the participant terminal supporting panoramic video playing.
In an embodiment of the present invention, the first reference terminal may be a video networking terminal, and step 1003 may include the following sub-steps:

In the repackaging process, since the first video data packet is a data packet encapsulated by adopting an ethernet protocol, the first video data packet can be firstly unpacked, and the bag body part can be extracted.
For panoramic video, a header part of a preset video networking protocol can be obtained, then a preset video type identifier corresponding to the panoramic video can be added in a designated field of the header part, and then the header part and the header part can be packaged, so that first video data after being re-packaged is obtained.
In an embodiment of the present invention, the method may further include the steps of:
when the first participant terminal is a participant terminal supporting panoramic video playing, acquiring a preset terminal identification, and generating a type notification message by adopting the preset terminal identification; and sending the type notification message to the conference management server.
In a specific implementation, a terminal type identifier of a participant terminal supporting panoramic video playing may be predefined as a preset terminal type identifier, and then when the first participant terminal is a participant terminal supporting panoramic video playing, the preset terminal identifier may be obtained.
After the preset terminal identifier is obtained, the first participant terminal adopts the preset terminal identifier to generate a type notification message, and the type notification message is sent to the conference management server so as to inform the conference management server of the video types supported to play.
After receiving the type notification message, the conference management server can analyze the type notification message, determine a terminal type identifier for characterizing the supported video playing type from the type notification message, and if the terminal type identifier is a preset terminal type identifier, send a reference terminal corresponding to the type notification message to be marked as a panoramic reference terminal supporting panoramic video playing.
