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. 5, 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.

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.
In this specification, the definition of label 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.

| 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.
