Computer realizes that high-definition quality video plays.
It should be noted that being not based on the internet of IP agreement depending on networking, but use V2V view networking technology and association
View covers small towns, Working level high definition real-time exchange network based on the building of operator's special line, nationwide.V2V agreement
It is on the basis of standard ethernet, the switch type applied to realtime video transmission designed for the extensive video exchange of support is assisted
View is a kind of independent agreement based on view networking framework.And the agreement depending on networking belongs to a kind of privately owned agreement, and it is existing
Integrated terminal and the agreement of view networking are incompatible, view networking institute cannot be supported functional, i.e., existing integrated terminal cannot
It applies in view networking.The agreement that integrated terminal proposed in the embodiment of the present invention can be networked by following view, is supported
Depending on networking, institute is functional, and all terminals of compatible view networking.
Embodiment in order to enable those skilled in the art to better understand the present invention is introduced to depending on networking below:
Depending on networking, applied portion of techniques is as described below:
Network technology (Network Technology)
Traditional ethernet (Ethernet) is improved depending on the network technology innovation networked, with potential huge on network
Video flow.(Circuit is exchanged different from simple network packet packet switch (Packet Switching) or lattice network
Switching), Streaming demand is met using Packet Switching depending on networking technology.Has grouping depending on networking technology
Flexible, the simple and low price of exchange, is provided simultaneously with the quality and safety assurance of circuit switching, it is virtually electric to realize the whole network switch type
The seamless connection of road and data format.
Switching technology (Switching Technology)
Two advantages of asynchronous and packet switch that Ethernet is used depending on networking eliminate Ethernet under the premise of complete compatible and lack
It falls into, has the end-to-end seamless connection of the whole network, direct user terminal, directly carrying IP data packet.User data is in network-wide basis
It is not required to any format conversion.It is the more advanced form of Ethernet depending on networking, is a real-time exchange platform, can be realized at present mutually
The whole network large-scale high-definition realtime video transmission that networking cannot achieve pushes numerous network video applications to high Qinghua, unitizes.
Server technology (Server Technology)
It is different from traditional server, its Streaming Media depending on the server technology in networking and unified video platform
Transmission be built upon it is connection-oriented on the basis of, data-handling capacity is unrelated with flow, communication time, single network layer energy
Enough transmitted comprising signaling and data.For voice and video business, handled depending on networking and unified video platform Streaming Media
Complexity many simpler than data processing, efficiency substantially increase hundred times or more than traditional server.
Reservoir technology (Storage Technology)
The ultrahigh speed reservoir technology of unified video platform in order to adapt to the media content of vast capacity and super-flow and
Using state-of-the-art real time operating system, the programme information in server instruction is mapped to specific hard drive space, media
Content is no longer pass through server, and moment is directly delivered to user terminal, and user waits typical time less than 0.2 second.It optimizes
Sector distribution greatly reduces the mechanical movement of hard disc magnetic head tracking, and resource consumption only accounts for the 20% of the internet ad eundem IP, but
The concurrent flow greater than 3 times of traditional disk array is generated, overall efficiency promotes 10 times or more.
Network security technology (Network Security Technology)
Depending on the structural design networked by servicing independent licence system, equipment and the modes such as user data is completely isolated every time
The network security problem that puzzlement internet has thoroughly been eradicated from structure, does not need antivirus applet, firewall generally, has prevented black
The attack of visitor and virus, structural carefree secure network is provided for user.
It services innovative technology (Service Innovation Technology)
Business and transmission are fused together by unified video platform, whether single user, private user or a net
The sum total of network is all only primary automatic connection.User terminal, set-top box or PC are attached directly to unified video platform, obtain rich
The multimedia video service of rich colorful various forms.Unified video platform is traditional to substitute with table schema using " menu type "
Complicated applications programming, considerably less code, which can be used, can be realized complicated application, realize the new business innovation of " endless ".

payload(PDU)、CRC。
As shown in the table, the data packet for accessing net mainly includes following sections:
| DA | SA | Reserved | Payload | CRC |
Wherein:
Destination address (DA) is made of 8 bytes (byte), and first character section indicates type (such as the various associations of data packet
Discuss packet, multicast packet, unicast packet etc.), be up to 256 kinds of possibility, the second byte to the 6th byte is metropolitan area net address,
Seven, the 8th bytes are access net address；
Source address (SA) is also to be made of 8 bytes (byte), is defined identical as destination address (DA)；
Reserve bytes are made of 2 bytes；
The part payload has different length according to the type of different datagrams, is if it is various protocol packages
64 bytes are 32+1024=1056 bytes if it is single group unicast packets words, are not restricted to above 2 kinds certainly；
CRC is made of 4 bytes, and calculation method follows the Ethernet CRC algorithm of standard.
2.2 Metropolitan Area Network (MAN) packet definitions
The topology of Metropolitan Area Network (MAN) is pattern, may there is 2 kinds, connection even of more than two kinds, i.e. node switching between two equipment
It can all can exceed that 2 kinds between machine and node server, node switch and node switch, node switch and node server
Connection.But the metropolitan area net address of metropolitan area network equipment is uniquely, to close to accurately describe the connection between metropolitan area network equipment
System, introduces parameter in embodiments of the present invention: label, uniquely to describe a metropolitan area network equipment.
(Multi-Protocol Label Switch, multiprotocol label are handed over by the definition of label and MPLS in this specification
Change) label definition it is similar, it is assumed that between equipment A and equipment B there are two connection, then data packet from equipment A to equipment B just
There are 2 labels, data packet also there are 2 labels from equipment B to equipment A.Label is divided into label, outgoing label, it is assumed that data packet enters
The label (entering label) of equipment A is 0x0000, and the label (outgoing label) when this data packet leaves equipment A may reform into
0x0001.The networking process of Metropolitan Area Network (MAN) is to enter network process under centralized control, also means that address distribution, the label of Metropolitan Area Network (MAN)
Distribution be all to be dominated by metropolitan area server, node switch, node server be all passively execute, this point with
The label distribution of MPLS is different, and the distribution of the label of MPLS is the result that interchanger, server are negotiated mutually.
As shown in the table, the data packet of Metropolitan Area Network (MAN) mainly includes following sections:
| DA | SA | Reserved | Label | Payload | CRC |
That is destination address (DA), source address (SA), reserve bytes (Reserved), label, payload (PDU), CRC.Its
In, the format of label, which can refer to, such as gives a definition: label is 32bit, wherein high 16bit retains, only with low 16bit, its position
Set is between the reserve bytes and payload of data packet.
Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, camera is integrated into
In video conference terminal applied to view networking, the multimedia terminal for being applied to view networking is formed, to solve existing view networking
