2. Video networking 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 |
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (e.g. various protocol packets, multicast data packets, unicast data packets, etc.), there are at most 256 possibilities, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses.
The Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA).
The reserved byte consists of 2 bytes.
The payload part has different lengths according to types of different datagrams, and is 64 bytes if the type of the datagram is a variety of protocol packets, or is 1056 bytes if the type of the datagram is a unicast packet, but is not limited to the above 2 types.
The CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of a Label of Multi-Protocol Label switching (MPLS), and assuming that there are two connections between a device a and a device B, there are 2 labels for a packet from the device a to the device B, and 2 labels for a packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, and a first video network terminal may access the video network and the internet, respectively, under the condition that a second network unit is in a first operating mode or a second operating mode, in compliance with the protocols of the internet and the video network.

The method specifically comprises the following steps:
In the embodiment of the present invention, the first video network terminal may be a network communication device, which has functions of connecting the user terminal, accessing the video network, accessing the internet, and forwarding the audio/video data packet. In practical applications, when accessing a network (video network or internet), the first video network terminal may include at least a first network unit and a second network unit, where both the first network unit and the second network unit may be connected to a central processing unit of the first video network terminal, and the central processing unit controls the first network unit and the second network unit. The first network unit and the second network unit may be network units supporting any network service, network standard or network interface, for example, the first network unit may be a 4G wireless network unit, a wired network unit, and the like, and the second network unit may be a WiFi wireless network unit, and the like. When the first network unit is a 4G wireless network unit, a sim card supporting any network service may be inserted into the first network unit. When the first network unit is a 4G wireless network unit, the first network unit may further support an esim card of any network service, that is, an embedded sim card. When the second network unit is a WiFi wireless network unit, the second network unit may support a wireless network signal in a 2.4GHz band, and may also support a wireless network signal in a 5GHz band.
For the WiFi wireless network unit, there are two operation modes, which are a first operation mode (base station mode) and a second operation mode (hotspot mode). The WiFi wireless network unit in the base station mode does not accept wireless access of network equipment, but can be connected to other wireless networks or hotspots, and a common wireless network card operates in the base station mode. The WiFi wireless network unit in the hotspot mode allows wireless access of the network device, and a common wireless router or network bridge operates in the hotspot mode.
In the embodiment of the invention, under the condition that the WiFi wireless network unit is in the base station mode, if the first video network terminal cannot be connected to a special network interface to access the video network, the video network can be accessed by using the 4G wireless network unit or the WiFi wireless network unit. Specifically, the network connection between the first video network terminal and the video network node server may be established by using a 4G wireless network unit or a WiFi wireless network unit according to a preset first network configuration parameter. The first network configuration parameter may include a port of the first video network terminal for communicating with the video network node server, a network address and a port of the video network node server, a protocol followed by the network connection, a type and a format of a send-receive message for establishing the network connection, and the like. The first network configuration parameter can be generated by the first control terminal or the second control terminal and sent to the first video network terminal. In practical application, the first video network terminal can utilize a built-in bluetooth unit to establish connection with the first control terminal, and at this moment, the first control terminal can be a mobile terminal with a bluetooth connection function, such as a smart phone and a tablet computer. The first video network terminal can utilize a built-in direct connection unit such as a serial interface unit, a parallel interface unit, a universal serial bus unit and the like to establish connection with the second control terminal, and at this time, the second control terminal can be a computer or a set top box and the like.
