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.

The definition of the label in this specification is similar to the definition of the label of Multi-Protocol label switching (MP L S), and assuming that there are two connections between device a and device B, there are 2 labels for the packet from device a to device B, and there are 2 labels for the packet from device B to device a. the label is divided into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering device a is 0x0000, the label (outgoing label) of the packet leaving device a may become 0x 0001.

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.

Fig. 5 shows a video networking system provided by an embodiment of the present invention, which includes: the remote controller 51, the video network terminal 52 and the display 53 connected with the video network terminal 52, wherein the video network terminal 52 is provided with a first Bluetooth module 521; the remote controller 51 is provided with a second bluetooth module 511, a first main control module 512 and a first control key 513;

the second bluetooth module 511 and the first control key 513 are respectively connected with the first main control module 512; the first control key 513 sends a switching signal to the first main control module 512, and the first main control module 512 receives the switching signal and starts or stops sending a power supply signal to the second bluetooth module 511.

It should be noted that the remote controller 51 is wirelessly connected to the video network terminal 52, and the user operates the video network terminal 52 through the remote controller 51 and views through the display 53. The first master control module 512 may be a micro control unit, but is not limited thereto. The first main control module 512 can control whether and how the second bluetooth module 511 starts to operate. For example, after receiving the switching signal sent by the first control key 513, the first main control module 512 sends a power supply signal to the second bluetooth module 511, so that the second bluetooth module 511 powers on and starts to operate, preferably, after the second bluetooth module 511 powers on, the second bluetooth module 511 is set to the slave mode by default, and sets the name as a preset name, where the preset name may be YK-VisionVera, but is not limited thereto. After the first main control module 512 receives the switching signal sent by the first control key 513 again, the first main control module stops sending the power supply signal to the second bluetooth module 511, so that the second bluetooth module 511 powers off and stops working.

Of course, the remote controller 51 may further include an infrared communication module, so that the remote controller 51 has two communication modes, i.e., infrared communication and bluetooth communication. Preferably, when the remote controller 51 is powered on, the infrared communication module is turned on by default and the second dental module 511 is turned off. The remote controller 51 operates the video network terminal 52 by means of infrared communication. The user presses the first control key 513, so that the first control key 513 sends a switching signal to the first main control module 512, the first main control module 512 starts sending a power supply signal to the second bluetooth module 511 according to the received switching signal, the second bluetooth module 511 is powered on to start working, meanwhile, the infrared communication module stops sending the power supply signal to stop working when being powered off, and at this time, the remote controller 51 controls the video networking terminal 52 in a bluetooth communication mode. The remote control 51 also comprises a plurality of other keys for operating the video network terminal 52, but the first control key 513 is only used for establishing a bluetooth connection between the remote control 51 and the video network terminal 52.

When the terminal 52 of the video network is powered on, the first bluetooth module 521 can be set to an off state or an on state by default. When the video network terminal 52 is powered on and the first bluetooth module 521 is set to the off state by default, the remote controller 51 may control the video network terminal 52 in an infrared communication manner, and switch the state of the first bluetooth module 52 to the on state. For example, when the terminal 52 of the video network is powered on, the display 53 directly or indirectly displays the operation interface of the terminal 52 of the video network. The user controls the internet-of-sight terminal 52 through the remote controller 51, so as to switch the state of the first bluetooth module 521 to the open state. Of course, when the video network terminal 52 is powered on, the first bluetooth module 521 may be in an open state. When the first bluetooth module 521 is in the open state, the first bluetooth module 521 defaults to the master mode and starts searching for a nearby bluetooth device in the slave mode. In order to facilitate rapid pairing, when the first bluetooth module 521 searches for a bluetooth device in the slave mode, if a bluetooth device with a preset name is found, the first bluetooth module directly initiates active connection to perform pairing operation. The default name may be YK-VisionVera, but is not limited thereto. Preferably, the same preset name is stored in both the remote controller 51 and the video network terminal 52 which are used in a matched manner, the name of the bluetooth module of the remote controller 51 is the preset name, and the video network terminal 52 directly initiates active connection for pairing when encountering the preset name when searching for nearby slave mode bluetooth devices. Preferably, the pairing condition of the video network terminal 52 and the remote controller 51 can also be displayed through the display 53. The video network terminal 52 and the display 53 are connected by a high-definition multimedia interface cable.

In the embodiment of the present invention, by setting the first bluetooth module 521 on the video network terminal 52 and the second bluetooth module 511 on the remote controller 51, the remote controller 51 and the video network terminal 52 can perform bluetooth communication, thereby realizing transmission of audio and video data between the remote controller 51 and the video network terminal 52; meanwhile, the first control key 513 is additionally arranged on the remote controller 51 to control the second Bluetooth module 511, so that when a user uses the remote controller 51, the user can select between the original infrared communication mode and the additionally arranged Bluetooth communication mode, and the flexibility of user selection is improved.

It should be noted that the first bluetooth receiving and sending unit, the first bluetooth control unit, and the first bluetooth transparent transmission unit are common functional units used for bluetooth communication in the bluetooth device, and are not described herein again. The first instruction parsing unit may identify and parse the control instruction, and preferably, may adopt an AT (attention) instruction as the control instruction, that is, the first instruction parsing unit is a first AT instruction parsing unit; of course other types of control instructions may be employed. Wherein the AT command is a command applied to connection and communication between the terminal device and the personal computer application.

The first master control module 512 includes: the remote control device comprises a first instruction unit, a remote control key unit, a universal asynchronous receiving and transmitting transmitter application program unit and a second universal asynchronous receiving and transmitting transmitter interface;

When the AT command is used as the control command, the first command unit is the first AT command unit.

Referring to fig. 5 and fig. 6, in the embodiment of the present invention, when the remote controller is powered on, the user presses the first control key 513, so that the first control key 513 sends the switching signal to the first main control module 512, and the first main control module 512 starts to send the power supply signal to the second bluetooth module 511 according to the received switching signal, so that the second bluetooth module 511 is powered on and starts to work. Meanwhile, the first main control module 512 encapsulates the slave mode command data packet through the first command unit, and sends the slave mode command data packet to the first command parsing unit through the first and second universal asynchronous transceiver/transmitter interfaces. After the first instruction parsing unit parses out the slave mode setting instruction, the second bluetooth module 511 is set to the slave mode state by the first bluetooth control unit, and the name of the bluetooth device is set by default as: YK-VisionVera; and then the remote controller is matched with the video network terminal through the first Bluetooth receiving and sending unit. And after the pairing is successful, the second bluetooth module 511 enters the transparent transmission mode through the first bluetooth transparent transmission unit. Therefore, the remote control key unit of the remote controller converts the key instruction into a corresponding control instruction, and then the control instruction is transmitted to the second Bluetooth module 511 through the universal asynchronous receiving and transmitting transmitter interface, and the second Bluetooth module 511 transparently transmits the control instruction to the first Bluetooth receiving and transmitting unit through the transparent transmission mode, and then the control instruction is transmitted to the remote controlled video network terminal.
