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 characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, following a protocol of the video network, the video network terminal responds to a trigger operation of a user for a certain monitoring terminal, and determines whether a display interface of another monitoring terminal exists currently, if so, the video network terminal automatically closes the display interface, and simultaneously sends a display request for displaying video data of the certain monitoring terminal to the video network node server, so as to display the video data of the certain monitoring terminal pushed by the video network node server in a preset display area.

Specifically, the video network terminal may display video data of the monitoring terminal in a preset display area.
It should be noted that the video network terminal may only display the video data of one monitoring terminal in the display area, or may display the video data of a plurality of monitoring terminals in the display area.

In the embodiment of the present invention, the triggering operation of the user for any monitoring terminal on the map may include, but is not limited to: clicking operation (such as double-click operation) of a user on a monitoring icon of any monitoring terminal on the map, clicking operation (such as double-click operation) of the user on relevant information of any monitoring terminal on the map, and the like. The relevant information of the monitoring terminal may be displayed in a set position or a set range in a list form, for example, the relevant information list is displayed at a right side position of a map of the video network terminal, or the relevant information list is displayed in an upper right range of a monitoring icon of the monitoring terminal.
In the embodiment of the invention, when the video network terminal judges whether the display interface of any monitoring terminal exists, whether the display interface of the video data of any monitoring terminal exists in the display area can be judged.
And step 504, the video network terminal closes the display interface, generates and sends a display request of the monitoring terminal corresponding to the triggering operation to the video network node server.
In the embodiment of the invention, after the video network terminal determines that the display interface of the video data exists in the display area, the display interface can be automatically closed, and at the moment, no video data exists in the display area for displaying. Meanwhile, the video network terminal can also acquire relevant information of the monitoring terminal corresponding to the triggering operation according to the operation information of the triggering operation, generate a display request of the monitoring terminal corresponding to the triggering operation according to the relevant information, and send the display request to the video network node server. For example, a user double clicks a monitoring icon of the monitoring terminal b on a map of the video networking terminal a, the video networking terminal a determines that video data of the monitoring terminal c is being displayed in a display area, that is, a display interface d of the video data of the monitoring terminal c exists in the display area, the video networking terminal a closes the display interface d, generates a display request e of the monitoring terminal b according to related information of the monitoring terminal b, and sends the display request e to the video networking node server F.
And 505, the video network terminal generates and sends a display request of the monitoring terminal corresponding to the triggering operation to the video network node server.
One difference between this step 505 and the above step 504 is that the video network terminal automatically closes the display interface of the video data in step 504, and the display interface of the video data does not exist in step 505. The step 505 is the same as the step 504 described above in that the video network terminal generates and sends the display request to the video network node server, which may specifically refer to the related description in the step 504, and is not described herein again.
For the above step 504 and step 505, the node server of the video network is configured to push the video data of the monitoring terminal corresponding to the trigger operation to the terminal of the video network according to the display request. Specifically, the node server of the video network may determine a unique monitoring terminal according to the relevant information of the monitoring terminal included in the display request, and then push the video data of the unique monitoring terminal to the video network terminal.
In step 506, the video network terminal displays the video data from the video network node server in a preset display area.
For example, the video network terminal a receives video data from the monitoring terminal b of the video network node server J, and the video network terminal a displays a display interface containing the video data of the monitoring terminal b in a display area.
Based on the above description about the embodiment of the video data processing method, a method for switching video data by using a video networking GIS sky-eye scheduling application platform is introduced below, as shown in fig. 6, the method involves a video networking node server and a video networking GIS sky-eye scheduling application platform, wherein the video networking GIS sky-eye scheduling application platform obtains relevant information of each monitoring terminal from the video networking node server, and renders point locations where each monitoring terminal is located on a map. The user double clicks the point location where a certain monitoring terminal is located on the map, at the moment, the video networking GIS sky eye scheduling application platform judges whether video data of other monitoring terminals are being displayed or not, if the video data exist, the video networking GIS sky eye scheduling application platform closes a display interface of the video data being displayed, and sends a display request to the video networking node server so as to request for displaying the video data of the monitoring terminal corresponding to the double-clicked point location. And the video network node server receives the display request, determines the monitoring terminal corresponding to the double-click point according to the related information of the monitoring terminal contained in the display request, and further pushes the determined video data of the monitoring terminal to the video network GIS sky eye scheduling application platform. The video network GIS sky eye scheduling application platform displays video data of the monitoring terminal corresponding to the double-click point location, and switching operation of the video data is achieved.
The embodiment of the invention is applied to the video network, and the video network can comprise a video network node server and a video network terminal, wherein the video network node server is communicated with the video network terminal, the video network node server is used for managing the monitoring terminal connected with the video network node server, and the video network terminal is used for displaying the relevant information of the monitoring terminal.
In the embodiment of the invention, the video network terminal receives a plurality of monitoring point data from the video network node server, wherein each monitoring point data comprises the relevant information of the monitoring terminal connected with the video network node server. And the video network terminal displays the monitoring terminal on a map of the video network terminal according to the received monitoring point data. The user can look over the video data of any monitor terminal on the map of the video network terminal, and after the user carries out trigger operation to a certain monitor terminal on the map, the video network terminal can respond to the trigger operation and judge whether the video network terminal has a display interface of the monitor terminal, and the display interface can be the display interface of other monitor terminals except the certain monitor terminal. And if the video network terminal has the display interfaces of other monitoring terminals, the video network terminal closes the display interface, and simultaneously generates and sends the display request of a certain monitoring terminal to the video network node server. And the video network node server pushes the video data of the certain monitoring terminal to the video network terminal according to the display request, and the video network terminal displays the received video data in a preset display area.
The embodiment of the invention applies the characteristics of the video network, when a user wants to check the video data of a certain monitoring terminal on the video network terminal, the video network terminal firstly judges whether the video data of other monitoring terminals are displayed, if the video data of other monitoring terminals are displayed, the video network terminal automatically closes the display interface of the video data being displayed, sends the display request of the video data of the monitoring terminal to be checked by the user to the video network node server, and then displays the video data returned by the video network node server. The embodiment of the invention can be applied to a video networking GIS sky-eye scheduling application platform, avoids the operation that a user manually closes a display interface of one video data and manually opens a display interface of another video data, and greatly improves the simplicity of the operation of displaying the video data.
