And then, in the process of transmitting the monitoring video code stream data packet added with the packet number to the terminal, the video network cooperative transmission server detects whether the packet number of the currently transmitted monitoring video code stream data packet is 1 in real time, if so, the monitoring name of the target monitoring video corresponding to the monitoring video code stream data packet is inquired from the monitoring information stored in the video network cooperative transmission server, and the monitoring name of the target monitoring video is transmitted to the terminal at the same time when the monitoring video code stream data packet with the packet number of 1 is transmitted.
And finally, the terminal superimposes and displays the monitoring name of the target monitoring video in the display picture at the same time of displaying the video frame.
Referring to fig. 1, a flowchart of steps of a method for displaying monitoring data according to the present invention is shown, and the method is applied to a video networking corotation server, and may specifically include the following steps:

The monitoring video code stream at least comprises one frame of video frame, and each video frame comprises a plurality of monitoring video code stream data packets. In this embodiment, a frame of video frame may be understood as a frame of monitor screen data of a monitor video.
And after receiving the monitoring video code stream, the video networking co-rotating server analyzes the monitoring video code stream in real time to obtain at least one frame of video frame.

And the video networking co-rotating server transmits the monitoring video code stream with the packet number to the terminal in the form of a monitoring video code stream data packet.
Step 102, in the process of pushing the monitoring video code stream, judging whether the packet number carried by the current pushed monitoring video code stream data packet is the first packet number in a single-frame video frame;
in a specific implementation, in a process of pushing a monitoring video code stream to a terminal, a video network co-rotating server sends a monitoring video code stream data packet with a packet number to the terminal, and in a sending process, whether the packet number carried by the monitoring video code stream data packet is the first packet number of a corresponding video frame is detected in real time according to the packet number of the currently sent monitoring video code stream data packet. Wherein the video frame comprises a plurality of surveillance video code stream data packets.
And step 103, inquiring the monitoring name of the monitoring video code stream and sending the monitoring name to the terminal when the packet number carried by the currently pushed monitoring video code stream packet is the first packet number in a single-frame video frame, so that the terminal displays the monitoring name in a superposition way during the output of the video frame.
In a specific implementation, when the video network coordination service detects that the packet number carried by the currently pushed monitoring video code stream data packet is the first packet number, the monitoring name of the target monitoring video corresponding to the monitoring video code stream is queried in the monitoring information of the monitoring video stored by the video network coordination service, and when the monitoring video code stream data packet carrying the first packet number is sent, the monitoring name corresponding to the monitoring video is sent to the terminal.
After receiving all the monitoring video code stream data packets contained in a frame of video frame, the terminal sequentially outputs and displays the video frame according to the packet numbers carried by the monitoring video code stream data packets in the video frame to form a monitoring picture, and the currently received monitoring names are displayed in the monitoring picture in a superposition manner.
In the embodiment of the invention, the target monitoring video can be sent to the terminal through the video networking cooperative service by acquiring the monitoring video code stream and pushing the monitoring video code stream to the terminal in the form of the monitoring video code stream data packet, so that the cross-network type transmission of the target monitoring video can be realized; the method comprises the steps that whether a packet number carried by a current pushed monitoring video code stream data packet is the first packet number in a single-frame video frame or not is judged, when the packet number carried by the current pushed monitoring video code stream data packet is the first packet number in the single-frame video frame, the monitoring name of the monitoring video code stream is inquired and sent to the terminal, so that a video network co-rotating server can ensure that each frame of video frame is transmitted and simultaneously transmits a monitoring name once, and each frame of video frame is associated with one monitoring name; and the terminal displays the monitoring names in a superposition manner during the video frame outputting process, so that each frame of video frame has monitoring names in the superposition manner when being outputted and displayed as a monitoring picture, and the phenomenon that the monitoring names are not existed or are incomplete in the monitoring picture in the prior art is overcome.
Referring to fig. 2, an operation example diagram of a monitoring data display method of the present invention is shown, and the method is applied to a video networking corotation server, and may specifically include the following steps:
step 201, receiving a monitoring video request sent by the terminal, wherein the monitoring video request carries a monitoring identifier of a requested target monitoring video;
in the embodiment of the invention, the video network coordination server receives a monitoring video request sent by a terminal, wherein the monitoring video request carries a monitoring identifier of a target monitoring video, and the monitoring identifier is a unique identifier of the target monitoring video.
Step 202, matching the monitoring identifier of the target monitoring video with the monitoring identifiers of the monitoring information of the plurality of monitoring videos;
in the embodiment of the invention, a plurality of monitoring videos are hung under a monitoring platform, and the monitoring platform sends monitoring information of all the hung monitoring videos to a video network cooperative server for storage, wherein the monitoring information of a single monitoring video at least comprises a monitoring name and a monitoring identifier of the monitoring video.
When a new monitoring video is added or an existing monitoring video is deleted under the monitoring platform, the monitoring platform can send the monitoring information of the newly added or deleted monitoring video to the video network cooperative conversion server, so that the video network cooperative conversion server adds or deletes the monitoring information of the corresponding monitoring video in the stored monitoring information.
Therefore, the video networking co-rotating server stores monitoring information of a plurality of monitoring videos, and the monitoring information of a single monitoring video at least comprises a monitoring name and a monitoring identifier of the monitoring video.
The video networking cooperative conversion server firstly analyzes the monitoring video request to obtain a monitoring identifier of a target monitoring video; and then, the monitoring identification is matched with the monitoring identification of each monitoring information stored in the video networking cooperative server one by the video networking cooperative server.
Step 203, if the matching is successful, a stream regulating request is sent to a monitoring platform, wherein the stream regulating request carries a monitoring identifier of the target monitoring video;
in the embodiment of the invention, the video networking cooperative server inquires a monitoring identifier matched with the monitoring identifier of the target monitoring video in the stored numerous monitoring information, and indicates that the target monitoring video exists in the monitoring platform, and generates a flow regulating request according to the monitoring identifier of the target monitoring video, and sends the flow regulating request to the monitoring platform.
If the matching is not successful, the video networking co-rotating server returns an error message to the terminal, so that an operator can know that a target monitoring video corresponding to the monitoring identifier is not available in the monitoring platform through the error message.
Step 204, receiving the target monitoring video returned by the monitoring platform in the form of a monitoring video code stream;
in the embodiment of the invention, after receiving the flow regulating request sent by the video networking coordination server, the monitoring platform analyzes the flow regulating request to obtain the monitoring identification of the target monitoring video. And the monitoring platform finds out a target monitoring video corresponding to the monitoring identifier from the monitored videos hung below according to the monitoring identifier. In this embodiment, the target monitoring video is that the camera sends the monitoring picture data to the monitoring platform in real time, so the monitoring platform sends the target monitoring video to the video network co-rotating server in the form of a monitoring video code stream, and the monitoring video code stream at least comprises one frame of video frame.
Step 205, obtaining a protocol format supported by the terminal;
step 206, converting the protocol format of the monitoring video code stream into a protocol format supported by the terminal;
in the embodiment of the invention, because the protocol format supported by the terminal may not be consistent with the protocol format of the monitoring video code stream sent by the monitoring platform, the video networking cooperative conversion server needs to acquire the protocol format supported by the terminal, so that the video networking cooperative conversion service converts the protocol format of the monitoring video code stream into the protocol format supported by the terminal.
Step 207, analyzing the monitoring video code stream to obtain at least one frame of video frame;
in the embodiment of the invention, the video networking co-rotating server analyzes the monitoring video code stream after the format conversion is completed, and obtains the video frames contained in the monitoring video code stream. And each frame of video frame includes a plurality of surveillance video code stream data packets.
Step 208, adding packet numbers to the plurality of surveillance video code stream data packets contained in each frame of video frame respectively;
in the embodiment of the invention, the video networking co-rotating server adds packet numbers to the monitoring video code stream data packets in each frame of video frame respectively, and the packet numbers of the monitoring video code stream data packets in each frame of video frame are all from the number 1.
Step 209, pushing the monitoring video code stream after protocol format conversion to the terminal in the form of monitoring video code stream data packets;
in the embodiment of the invention, the video networking co-rotating server transmits the monitoring video code stream which is converted in protocol format and carries the packet number to the terminal in the form of a monitoring video code stream data packet. That is, the video networking co-rotating server will send the data packets contained in the video frames to the terminal one by one according to the video frames as units, and then send the video frames of the next frame. Or the video networking co-rotating server and the terminal transmit video frames simultaneously in a multi-channel mode.
Step 210, in the process of pushing the surveillance video code stream, judging whether the packet number carried by the currently pushed surveillance video code stream data packet is the first packet number in a single frame video frame, wherein the video frame comprises a plurality of surveillance video code stream data packets;
in the embodiment of the invention, in the process of sending the monitoring video code stream to the terminal, the video networking co-rotating server can judge whether the currently sent monitoring video code stream data packet is the first data packet according to the packet number in real time, for example, judge whether the packet number of the currently sent monitoring video code stream data packet is number 1.
Step 211, when the packet number carried by the currently pushed surveillance video code stream packet is the first packet number in a single frame video frame, inquiring the surveillance name of the surveillance video code stream, and sending the surveillance name to the terminal, so that the terminal superimposes and displays the surveillance name during the period of outputting the video frame.
In the embodiment of the invention, when the current monitoring video code stream data packet pushed to the terminal by the video network cooperative server is a data packet with the packet number of 1 in the video frame, the video network cooperative server inquires a monitoring name corresponding to the monitoring identifier in monitoring information according to the monitoring identifier of the target monitoring video corresponding to the monitoring video code stream, and sends the monitoring name to the terminal. And the terminal outputs a single-frame video frame according to the packet number and displays the single-frame video frame as a monitoring picture.

The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.
Server technology (Server Technology)
The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.

The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.
Network security technology (Network Security Technology)
The structural design of the video networking thoroughly structurally solves the network security problem puzzling the Internet by means of independent permission of each service, complete isolation of equipment and user data and the like, generally does not need antivirus programs or firewalls, eliminates attacks of hackers and viruses, and provides a structural carefree security network for users.
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.

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.

2. View networking data 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:
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.
The definition of label in this specification 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.
As shown in the following table, the data packet of the metropolitan area network mainly includes the following parts:
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.
