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 data processing scheme provided by the embodiment of the invention follows the protocol of the video network, so that the image transmission equipment can be used as a participant terminal to join in the video conference of the video network.

The data processing scheme of the embodiment of the invention can be applied to video conferences of video networking. The devices involved in video conferencing may include devices in the video network and devices in the internet. The video network can comprise a streaming media server, a video network server (can be the node server) and a video network terminal. A graph-passing device may be included in the internet.

The terminal of the video networking is a terminal for performing services based on the video networking protocol, and the terminal of the video networking may be various Set Top Boxes (STBs) and the like based on the video networking protocol. The video network terminal registers to the video network server to perform normal service, and the video network server allocates a video network number, a Media Access Control (MAC) address and the like for the video network terminal after successful registration. And the video network terminal logs in the video network server according to the video network number so as to be connected with the video network server. In the video network, each video network terminal can be distinguished through the video network number and the video network MAC address of the video network terminal.

The streaming media server may be connected to a plurality of image transmission devices on the internet. The image transmission device is also called a wireless video monitoring device or a wireless video server, or can be called a network camera. The vehicle-mounted mobile monitoring is adopted in typical application occasions, and the image transmission equipment is introduced on the basis of the traditional vehicle-mounted hard disk/SD card video recorder, so that the rear-end monitoring center personnel can check images in the vehicle driving process in real time while recording the images in the whole process, and can immediately deal with emergency situations. Such as police cars, road enforcement vehicles, securicars, buses, hazardous freight vehicles, river law enforcement boats, and the like. The image transmission device can be a 3G image transmission device, a 4G image transmission device and the like. The image transmission device may log in on the streaming media server, and after the log-in is successful, the streaming media server may store information of each image transmission device, where the information of the image transmission device may include a name, a geographic location (e.g., longitude and latitude), an IP address, and the like of the image transmission device.

The streaming media server can be understood as a gateway, and is responsible for accessing the image transmission device of the internet into the video network. The streaming media server can comprise a plurality of virtual terminals, and the virtual terminals serve as a bridge for the association between the internet and the video network. Each virtual terminal is respectively registered to the upper part of the video network server to carry out normal service, and the video network server can distribute video network numbers, video network MAC addresses and the like for each virtual terminal after successful registration. And each virtual terminal logs in the video network server according to the video network number so as to monitor the connection of the access server and the video network server. In the video network, the virtual terminals can be distinguished through the video network numbers and the video network MAC addresses of the virtual terminals.

Example one

Referring to fig. 5, a flowchart illustrating steps of a data processing method according to a first embodiment of the present invention is shown.

The data processing method of the embodiment of the invention can comprise the following steps:

step 501, after the image transmission device logs in the streaming media server, the streaming media server receives a live broadcast data packet based on an internet protocol, which is sent by the image transmission device in a release live broadcast manner.

The image transmission device can register on the streaming media server in a user mode, and information such as an account number, a password and the like is obtained after the registration is successful. The image transmission device may log in the streaming media server by using an account and a password, and after the login is successful, the image transmission device and the streaming media server may interact based on an Internet Protocol, such as an IP (Internet Protocol).

The image transmission equipment supports a live broadcast mode, can acquire data such as external audio and video streams, encodes the acquired data to serve as live broadcast data, and encapsulates the live broadcast data into a live broadcast data packet based on an internet protocol. The live broadcast data comprises audio live broadcast data and video live broadcast data, and the live broadcast data packet comprises an audio live broadcast data packet and a video live broadcast data packet. The live internet protocol-based data packet may include an internet packet header and an internet data body. The internet packet header may include information such as an IP address of the image transmission monitoring device, an IP address of the streaming media server, and a field for characterizing a data type, where the data type includes an audio type and a video type. The internet data body comprises specific live broadcast data.

And after successfully logging in the streaming media server, the image transmission equipment sends the live broadcast data packet based on the Internet protocol to the streaming media server in a live broadcast releasing mode.

In an optional implementation manner, after the streaming media server logs in the streaming media server by the image transmission device, a live channel corresponding to the image transmission device may also be established, where each image transmission device corresponds to one live channel. Therefore, after the graph transmission device successfully logs in the streaming media server, the graph transmission device sends the live broadcast data packet based on the internet protocol to a live broadcast channel corresponding to the graph transmission device in the streaming media server in a live broadcast releasing mode. And the streaming media server receives a live broadcast data packet which is sent by the image transmission equipment in a live broadcast mode and is based on an internet protocol through a live broadcast channel corresponding to the image transmission equipment.

Step 502, the streaming media server acquires the live broadcast data packet based on the internet protocol after the image transmission device joins the video conference of the video network.

In the video conference, the video conference can be established through the conference control software of the video network. For example, conference control software is used to select the participant terminals for group conference, set the roles (chairman, speech, participant, etc.) of the participant terminals in the conference, switch the roles of the participant terminals in the conference, and control the participant terminals to quit the conference. The conference control software may be installed on devices such as PCs (personal computers), mobile phones, tablets, etc.

The conference control software can send a conference invitation to the video networking terminal and the image transmission equipment so that the video networking terminal and the image transmission equipment are used as participant terminals to join in the video networking video conference. The conference control software sends an invitation to join the conference to the video network server. And the video networking server sends the meeting invitation aiming at the video networking terminal to the video networking terminal according to the downlink communication link configured for the video networking terminal. And the video network server sends the meeting invitation aiming at the image transmission equipment to the streaming media server according to the downlink communication link configured for the streaming media server, and then the streaming media server sends the meeting invitation to the image transmission equipment. And after the video network terminal and the image transmission equipment accept the invitation to join, returning an invitation accepting response according to the respective corresponding paths, thereby joining the video network terminal and the image transmission equipment as a participant terminal in the video conference of the video network. The video networking server can store information such as video networking numbers, video networking MAC addresses and roles of all the participant terminals in the video networking video conference, so that the video networking server can know which participant terminals the data is sent to after receiving the data sent by the speaking party.

After the graph transmission equipment is used as a participant terminal to join the video conference of the video network, the graph transmission equipment can be used as a speaking party, so that the streaming media server can obtain a live data packet which is sent by the graph transmission equipment after logging in and is based on an internet protocol, and then the live data packet is transmitted in the video conference of the video network.

In an alternative embodiment, the streaming media server may obtain, through the middleware, a live data packet based on an internet protocol, which is sent by the image transmission device in a live manner. Therefore, the streaming media server can create the middleware after the image transmission device joins the video conference of the video network. Middleware is software that provides a connection between system software and application software, and includes a set of services to facilitate communication between the various components of the software, particularly the centralized logic of the application software with respect to the system software.

The step of obtaining the live data packet based on the internet protocol may include: and pulling the live broadcast data packet based on the Internet protocol from the live broadcast channel corresponding to the image transmission equipment in a live broadcast watching mode through the middleware. The method for watching the live broadcast by the middleware is characterized in that the middleware is added into a watching list of a live broadcast source (namely, image transmission equipment), and the live broadcast source transmits a stream to a member of the live broadcast watching list in a traversing manner. The middleware has two functions, one is used as a live viewer to pull live data, and the other is used as a conference data source to send out the live data.

Step 503, the streaming media server converts the live data packet based on the internet protocol into a live data packet based on the video networking protocol.

The streaming media server and the video networking server are interacted based on a video networking protocol, and the streaming media server converts the live broadcast data packet based on the Internet protocol into a live broadcast data packet based on the video networking protocol.

In the implementation, the streaming media server analyzes the live data packet based on the internet protocol to obtain a video networking data body (namely, live data), and then encapsulates the live data based on the video networking protocol to obtain the live data packet based on the video networking protocol. The live data packet based on the video network protocol can comprise a video network packet header and a video network data body. The video network header may include information such as a video network number, a video network MAC address, and a field for characterizing a data type of a streaming server (specifically, a virtual terminal currently processing a live data packet), where the data type includes an audio type and a video type. The video network data body comprises specific live broadcast data.

And step 504, the streaming media server sends the live broadcast data packet based on the video networking protocol to a video networking terminal joining the video networking video conference through the video networking server.

And the streaming media server sends the live broadcast data packet based on the video networking protocol to a video networking server, and then the video networking server forwards the live broadcast data packet based on the video networking protocol to the video networking terminal added to the video networking video conference according to a downlink communication link configured for the video networking terminal added to the video networking video conference.

In practical applications, the video network is a network with a centralized control function, and includes a master control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is to configure a table for a downlink communication link of a current service by notifying a switching device by the master control server, and then transmit a data packet based on the configured table.

Namely, the communication method in the video network includes:

and the master control server configures the downlink communication link of the current service.

And transmitting the data packet of the current service sent by the source terminal to the target terminal according to the downlink communication link.

Further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

and a substep S11, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the main control server; and sending a port configuration command to the corresponding access switch according to the downlink communication port information of the access switch.

In sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in sub-step S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, where the service request protocol packet includes service type information, service content information, and an access network address of the target terminal.

Wherein, the service content information includes a service number.

And a substep S22, the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number.

In the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

And after receiving the live broadcast data packet, the video networking terminal joining the video networking video conference decodes and plays the live broadcast data packet.

In the embodiment of the invention, the image transmission equipment in the internet is used as a participant terminal to be added into the video conference of the video network, the streaming media server is used for realizing the conversion between the video networking protocol and the internet protocol, and the image transmission equipment can be used as a speaking party to send live data in a live broadcasting mode in the video conference of the video network, so that the diversity of the participant terminal is increased, the video network terminal added into the video conference of the video network can watch the live data, and the discussion and the like are carried out on the live data.

Example two

Referring to fig. 6, a flowchart illustrating steps of a data processing method according to a second embodiment of the present invention is shown.

step 601, after the image transmission device logs in the streaming media server, the streaming media server receives a live broadcast data packet based on an internet protocol, which is sent by the image transmission device in a release live broadcast manner.

Step 602, the streaming media server acquires the live broadcast data packet based on the internet protocol after the image transmission device joins the video conference.

Step 603, the streaming media server converts the live data packet based on the internet protocol into a live data packet based on the video networking protocol.

And step 604, the streaming media server sends the live broadcast data packet based on the video networking protocol to a video networking terminal joining the video networking video conference through the video networking server.

Steps 602-604 describe the data transmission process when the image transmission device is used as the speaking party in the video networking video conference. The following steps 605 to 607 describe a data transmission process when the video network terminal is a speaking party in the video network video conference.

And 605, when receiving a talk data packet based on a video networking protocol sent by a video networking terminal joining the video networking video conference, the streaming media server screens out an audio talk data packet from the talk data packet based on the video networking protocol.

And if the video networking terminal speaks in the video networking video conference, the speaking data is collected by the video networking terminal, the speaking data is encoded, and the video networking terminal is packaged into a speaking data packet based on a video networking protocol. The speech data comprises audio speech data and video speech data, and the speech data packet comprises an audio speech data packet and a video speech data packet. The talk data packet based on the video networking protocol may include a video networking packet header and a video networking data body. The video network header can include information such as a video network number, a video network MAC address, a field for representing a data type and the like of a video network terminal which makes a speech, wherein the data type comprises an audio type and a video type. The video network data body comprises specific speech data.

The video network terminal sends the speech data packet based on the video network protocol to the video network server, and the video network server forwards the speech data packet to other participant terminals including other video network terminals and image transmission equipment participating in the video network conference.

And for other video networking terminals participating in the video networking conference, the video networking server sends the speech data packet based on the video networking protocol to the other video networking terminals according to the downlink communication link configured for the other video networking terminals.

For the graph transmission device, the graph transmission device is connected with the streaming media server, and the streaming media server is connected with the video network server, so that the video network server sends the speech data packet based on the video network protocol to the streaming media server according to the downlink communication link configured for the streaming media server, and specifically, the speech data packet can be sent to the idle virtual terminal of the streaming media server.

After the streaming media server receives the speech data packets based on the video networking protocol, because the image transmission device usually has video input and audio input and output functions, the streaming media server screens the audio speech data packets from the speech data packets based on the video networking protocol. For video talk packets, they may be discarded.

In an alternative embodiment, the step of screening out the audio speech packet from the speech packets based on the video networking protocol may include: analyzing the speech data packet based on the video networking protocol, and extracting a field representing the data type carried in a packet header of the video networking; the data types comprise an audio type and a video type; and determining the speech data packet with the data type represented by the extracted field as the audio type as the audio speech data packet.

Step 606, the streaming media server converts the audio speech data packet into an audio speech data packet based on the internet protocol.

The streaming media server and the image transmission device interact based on an internet protocol, and the streaming media server converts an audio speech data packet based on the video networking protocol into an audio speech data packet based on the internet protocol.

In the implementation, the streaming media server analyzes the audio speech data packet based on the video networking protocol to obtain a video networking data body (that is, audio speech data), and then encapsulates the audio speech data based on the internet protocol to obtain the audio speech data packet based on the internet protocol. The internet protocol based audio talk data packet may include an internet packet header and an internet data body. The internet packet header may include information such as an IP address of the streaming media server, an IP address of the image transmission device, and a field for characterizing a data type, where the data type includes an audio type and a video type. The internet data body comprises specific audio speech data.

Step 607, the streaming media server sends the audio speech data packet based on the internet protocol to the map transmission device.

The streaming media server may establish an audio channel corresponding to the image transmission device after the image transmission device joins the video conference over the internet of view, and the audio channel may be used for the streaming media server to send audio speech data to the corresponding image transmission device. Therefore, the streaming media server transmits the audio speech data packet based on the internet protocol to the audio channel corresponding to the image transmission device, and transmits the audio speech data packet based on the internet protocol to the image transmission device through the audio channel.

And after receiving the audio speech data packet, the image transmission equipment decodes and plays the audio speech data packet.
