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
Wherein:
The Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, 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 different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length 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 the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the 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, the monitoring video processing scheme provided by the embodiment of the invention follows the protocol of the video network, and can realize that the video network monitoring and scheduling platform can uniformly control the monitoring video of the third-party monitoring platform.

The monitoring video processing method of the embodiment of the invention can be applied to a monitoring video processing system. The monitoring video processing system can comprise a video networking monitoring scheduling platform, a video networking message forwarding service, a video networking terminal and a protocol conversion gateway. The cooperative gateway is responsible for accessing monitoring resources (which can also be described as monitoring equipment) on the internet into the video network, so that browsing and controlling the monitoring resources on the internet in the video network are realized. The collaboration gateway may be connected to at least one third party monitoring platform located in the internet. And the third-party monitoring platform is accessed to the protocol gateway after registration is successful. Each third-party monitoring platform can be connected with a plurality of monitoring resources, and the cooperation gateway can record the information of the plurality of monitoring resources connected with the accessed third-party monitoring platform. The third-party monitoring platform can be a public security monitoring platform, a medical monitoring platform, and the like.
Referring to fig. 5, a flowchart illustrating steps of a monitoring video recording processing method according to a first embodiment of the present invention is shown.
The monitoring video processing method of the embodiment of the invention can comprise the following steps:
Step 501, the video networking monitoring and scheduling platform sends the target co-transmission gateway identifier and the target monitoring resource identifier to the video networking message forwarding service through WebSocket connection.
The video networking monitoring and dispatching platform and the video networking message forwarding service communicate through a WebSocket (network socket) connection. Therefore, before communication, the video networking monitoring and scheduling platform can judge whether the WebSocket network monitoring service is connected or not.
fig. 6 is a schematic diagram of a device interaction process according to a first embodiment of the present invention. As shown in fig. 6, the user can log in and access the video network monitoring and scheduling platform at a PC (Personal Computer) side, and select a target monitoring resource identifier at a resource list function page. The video networking monitoring and scheduling platform judges whether the WebSocket network monitoring service is connected or not. If not, prompting the user to connect; if so, the video networking monitoring and scheduling platform can acquire a target co-transformation gateway identifier according to the target monitoring resource identifier, and sends the target co-transformation gateway identifier and the target monitoring resource identifier to the video networking message forwarding service through WebSocket connection. The cooperative gateway identifier may be a main message number of the target cooperative gateway, and the target monitoring resource identifier may be an ID, a name, and the like of the target monitoring resource.
step 502, the video networking message forwarding service forwards the target co-forwarding gateway identifier and the target monitoring resource identifier to a pre-connected video networking terminal through a video networking transparent transmission protocol.
As shown in fig. 6, the video networking message forwarding service forwards the target coordination gateway identifier and the target monitoring resource identifier to a video networking terminal connected in advance. The video network terminal is a video network service landing device, an actual participant or a server of the video network service, and can be various conference set-top boxes, video telephone set-top boxes, operation trial set-top boxes and the like.
The transmission data in the video networking protocol has a special format, which is hexadecimal. Therefore, after receiving the target coordination gateway identifier and the target monitoring resource identifier sent by the video networking monitoring and scheduling platform, the video networking message forwarding service converts both the target coordination gateway identifier and the target monitoring resource identifier into a hexadecimal format. In the implementation, the information sent by the video networking monitoring and scheduling platform through the WebSocket connection is in a JSON (JavaScript Object Notation) format, and the video networking message forwarding service analyzes the character string in the JSON format and converts the target co-transfer gateway identifier and the target monitoring resource identifier in the JSON format into a hexadecimal format.
The video network comprises a video network server, the video network server manages video network services in a unified way, equipment for carrying out the video network services needs to be registered in the video network server, and the registered video network server distributes a Media Access Control (MAC) address, a video network number and the like for the registered equipment.
The message forwarding service of the video networking and the terminal of the video networking can communicate based on the transparent transmission protocol of the video networking. The video networking transparent protocol may comprise a first video networking transparent protocol and a second video networking transparent protocol. The first video network transparent transmission protocol is a transparent transmission protocol in a terminal-to-server direction, and the second video network transparent transmission protocol is a transparent transmission protocol in a server-to-terminal direction. For example, the first internet of view transparent transmission protocol is 8F85 protocol, and the second internet of view transparent transmission protocol is 8785 protocol.
Therefore, after the target coordination gateway identifier and the target monitoring resource identifier are both converted into hexadecimal formats, the video networking message forwarding service encapsulates the format-converted target coordination gateway identifier and the format-converted target monitoring resource identifier into a first video networking message based on the first video networking transparent transmission protocol, and sends the first video networking message to the video networking server. And the video networking server extracts the target coordination gateway identification after format conversion and the target monitoring resource identification after format conversion from the first video networking message, encapsulates the target coordination gateway identification after format conversion and the target monitoring resource identification after format conversion to a second video networking message based on a second video networking transparent transmission protocol, and sends the second video networking message to the video networking terminal connected in advance. The first video networking message and the second video networking message may further include information such as a video networking number of a video networking message forwarding service (a video networking number of a source device) and a video networking number of a video networking terminal (a video networking number of a destination device).
step 503, the video network terminal forwards the target monitoring resource identifier to the corotation gateway corresponding to the target corotation gateway identifier through the video network transparent transmission protocol.
As shown in fig. 6, the video network terminal forwards the target monitoring resource identifier to the cooperative gateway corresponding to the target cooperative gateway identifier.
and the video network terminal can determine the target cooperative gateway according to the target cooperative gateway identifier. The target monitoring resource identification and the target coordination gateway identification received by the video network terminal are both hexadecimal, so that the video network terminal does not need to convert the format of the information.
the video networking terminal and the protocol gateway can communicate based on a video networking transparent transmission protocol. And the video network terminal encapsulates the target monitoring resource identifier with the converted format to a third video network message based on the first video network transparent transmission protocol, and sends the third video network message to the video network server. And the video networking server extracts the target monitoring resource identifier after format conversion from the third video networking message, encapsulates the target monitoring resource identifier into a fourth video networking message based on a second video networking transparent transmission protocol, and sends the fourth video networking message to a coordination gateway corresponding to the target coordination gateway identifier. The third video networking message and the fourth video networking message may further include information such as a video networking number of the video networking terminal (a video networking number of the source device) and a video networking number of the protocol gateway (a video networking number of the destination device).
Step 504, the cooperation gateway calls the monitoring video of the monitoring resource corresponding to the target monitoring resource identifier from the third-party monitoring platform corresponding to the target monitoring resource identifier, and returns the monitoring video to the video networking terminal through a video networking datagram protocol.
After receiving the target monitoring resource identifier, the cooperation gateway can determine, according to the target monitoring resource identifier, a third-party monitoring platform to which the monitoring resource corresponding to the target monitoring resource identifier is connected (i.e., the third-party monitoring platform corresponding to the target monitoring resource identifier). And the cooperation gateway calls the monitoring video of the monitoring resource corresponding to the target monitoring resource identifier from the third-party monitoring platform corresponding to the target monitoring resource identifier.
In implementation, the cooperation gateway calls an SDK (Software Development Kit) plug-in of the third-party monitoring platform corresponding to the target monitoring resource identifier, and calls the monitoring video through the SDK plug-in.
The third-party monitoring platform is based on the communication of the national standard protocol, and the monitoring video called by the cooperation gateway is packaged based on the national standard protocol. And the cooperation gateway returns the monitoring video to the video network terminal through a video network datagram protocol, wherein the video network datagram protocol is a protocol for sending larger data in the video network. The protocol conversion gateway firstly decapsulates the monitoring video encapsulated based on the national standard protocol, then encapsulates the monitoring video into a fifth video network message based on the video network datagram protocol, sends the fifth video network message to the video network server, and the video network server forwards the fifth video network message to the video network terminal. The fifth video network message may further include information such as a video network MAC address of the coordination gateway (the video network MAC address of the source device) and a video network MAC address of the video network terminal (the video network MAC address of the destination device).
And 505, the video network terminal plays the monitoring video.
As shown in fig. 6, the coordination gateway calls a video stream (i.e., the monitoring video of the monitoring resource corresponding to the target monitoring resource identifier), returns the video stream to the video networking terminal, and the video networking terminal can play the video stream. In fig. 6, the video networking terminal may also return the monitoring video to the video streaming video networking message forwarding service, and then the video streaming is returned to the video networking monitoring scheduling platform by the video networking message forwarding service.
In the embodiment of the invention, the video network monitoring and dispatching platform can control the monitoring video in the third-party monitoring platform to be played on the video network terminal, so that the video network monitoring and dispatching platform can uniformly control the monitoring video of the third-party monitoring platform.
example two
referring to fig. 7, a flowchart illustrating steps of a monitoring video recording processing method according to a second embodiment of the present invention is shown.
The monitoring video processing method of the embodiment of the invention can comprise the following steps:
Step 701, the video networking monitoring and scheduling platform sends a terminal connection request carrying a target terminal identifier to the video networking message forwarding service through WebSocket connection.
After a user logs in and accesses the video network monitoring and scheduling platform at the PC terminal, the user can select the target terminal identification to be connected first so as to establish the connection between the video network monitoring and scheduling platform and the video network terminal corresponding to the target terminal identification, and the connected video network terminal is used for playing the monitoring video subsequently. And the video networking monitoring and scheduling platform sends the terminal connection request carrying the target terminal identification to the video networking message forwarding service through WebSocket connection.
Step 702, the video networking message forwarding service forwards the terminal connection request to the video networking terminal corresponding to the target terminal identifier through a video networking transparent transmission protocol.
Similar to step 502 above, the video networking message forwarding service first converts the target terminal identification into hexadecimal format. And the video networking message forwarding service encapsulates the terminal connection request carrying the target terminal identifier after format conversion to a sixth video networking message based on the first video networking transparent transmission protocol, and sends the sixth video networking message to the video networking server. And the video network server extracts the relevant data of the terminal connection request from the sixth video network message, encapsulates the data into a seventh video network message based on a second video network transparent transmission protocol, and sends the seventh video network message to the video network terminal corresponding to the target terminal identifier.
and step 703, the video network terminal returns the successful connection response to the video network message forwarding service through the video network transparent transmission protocol.
And after receiving the terminal connection request, the video networking terminal returns a connection success response. And the video network terminal encapsulates the successful connection response to the eighth video network message based on the first video network transparent transmission protocol, and sends the eighth video network message to the video network server. And the video network server extracts the relevant data of the successful connection response from the eighth video network message, encapsulates the eighth video network message into a ninth video network message based on a second video network transparent transmission protocol, and sends the ninth video network message to a video network message forwarding service.
Step 704, the video networking message forwarding service forwards the connection success response to the video networking monitoring and scheduling platform through WebSocket connection, and the video networking terminal is successfully connected.
Step 705, the video networking monitoring and scheduling platform sends the target coordination gateway identifier, the target monitoring resource identifier and the playing mode to the video networking message forwarding service through WebSocket connection.
after the video network terminal corresponding to the target video network terminal identification is connected, the user can select the target cooperation gateway identification and the target monitoring resource identification. In this embodiment, the user may also set a playing mode when the monitoring video is played. The playback manner includes at least one of a multiple of the playback rate and a designated playback time.
The difference between step 705 and the above step 501 is that the transmitted data is different, the data transmitted in step 501 is the target coordination gateway identifier and the target monitoring resource identifier, and the data transmitted in step 705 is the target coordination gateway identifier, the target monitoring resource identifier and the playing mode. For the transmission process, the related description of step 501 above may be referred to.
step 706, the video networking message forwarding service forwards the target coordination gateway identifier, the target monitoring resource identifier and the playing mode to a video networking terminal connected in advance through a video networking transparent transmission protocol.
the difference between step 706 and step 502 is that the transmitted data is different, the data transmitted in step 502 is the target coordination gateway identifier and the target monitoring resource identifier, and the data transmitted in step 706 is the target coordination gateway identifier, the target monitoring resource identifier and the playing mode. For the transmission process, refer to the related description of step 502 above.
And 707, the video network terminal forwards the target monitoring resource identifier to a coordination gateway corresponding to the target coordination gateway identifier through the video network transparent transmission protocol.
Step 708, the cooperation gateway calls the monitoring video of the monitoring resource corresponding to the target monitoring resource identifier from the third-party monitoring platform corresponding to the target monitoring resource identifier, and returns the monitoring video to the video networking terminal through a video networking datagram protocol.
and step 709, the video network terminal plays the monitoring video according to the playing mode.
Because the playing mode is set in the embodiment, when the video network terminal plays the monitoring video, the monitoring video is played according to the playing mode.
For example, if the playing mode includes a multiple of the playing rate, the video network terminal plays the monitoring video according to the rate corresponding to the multiple of the playing rate.
for example, the playing mode includes a designated playing time, and if the designated playing time includes a designated playing start time and a designated playing duration, the video network terminal plays the monitoring video with the designated playing duration from the designated start time. And if the appointed playing time comprises the appointed playing starting time and the appointed playing ending time, the video network terminal starts playing the monitoring video from the appointed starting time and finishes playing to the appointed ending time.
For example, the playing mode includes a multiple of the playing speed and the designated playing time, and the video network terminal plays the monitoring video according to the playing mode corresponding to the two.
in an optional implementation manner, in the process of playing the monitoring video by the video networking terminal, the user can also execute corresponding operation to trigger the video networking monitoring scheduling platform to generate a playing control instruction, and the video networking monitoring scheduling platform sends the playing control instruction to the video networking message forwarding service through WebSocket connection; the video networking message forwarding service forwards the playing control instruction to a video networking terminal through a video networking transparent transmission protocol; and the video network terminal responds to the playing control instruction to play and control the monitoring video. For example, if the playing control instruction may be a playing pause instruction, the video networking terminal pauses playing the monitoring video; if the playing control instruction can be a continuous playing instruction, the video network terminal continues to play the monitoring video. For the specific process of transmitting the play control command, similar to the process of transmitting information in the first embodiment, reference may be made to the related description of the first embodiment.
The embodiment of the invention can realize the playing of the monitoring video of the third-party monitoring platform, and can set the playing mode and control the pause, the continuation and the like of the playing.
