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.

Referring to fig. 5, a flowchart illustrating steps of pushing business card information based on a video conference according to an embodiment of the present invention is shown, where the method is applied in a video network, and may specifically include the following steps:

step 501, a service server receives conference video data collected by the video network terminal through the video network server.

As shown in fig. 6, a video network server, one or more video network terminals (e.g., set-top boxes), and a service server are deployed in the video network, and the one or more video network terminals and the service server are accessed into the video network server.

The video network terminal or terminals are arranged in a conference room, the video network terminal or terminals can be connected with a camera, some video network terminals can be connected with a plurality of business card displays, and the business card displays are generally placed on a conference table and in front of users participating in the conference.

For the cameras, since the camera area of the camera is small, such as the area accommodating 9-16 persons, if the area of the conference room is small, the number of the deployed cameras is one, and if the area of the conference room is large, the number of the deployed cameras is two or more, each camera faces to a different camera area, thereby covering the whole conference room.

The business card displays can be accessed into the switch through wires or wireless (such as Bluetooth), the switch assigns an IP address to each business card display, and the switch is connected with the video network terminal.

In the video conference process, the camera collects video data (namely conference video data) and sends the video data to the video networking terminal, and the video networking terminal generates a corresponding data packet according to a video networking protocol and sends the data packet to the video networking server.

And after receiving the opening video data, the video network server forwards the opening video data to the service server.

In the video network, a video network server and a video network terminal may encapsulate a data packet of video data through the following 2000 specification of a video network protocol for transmission:

it should be noted that in the process of the video conference, the positions where the participating users sit may be changed due to the situations of speaking and the like of the participating users, so that the video networking terminal may collect the participating video data once every certain time (e.g., 3 minutes or 5 minutes) and upload the video data to the service server.

Step 502, the service server identifies conference-participating face data of the conference-participating user in the conference video data.

The service server can extract multi-frame image data from the starting video data and carry out face detection, namely, the position and the size of a face image are accurately calibrated in the image data.

The face image contains abundant pattern features, such as histogram features, color features, template features, structural features and Haar features, etc., and the face detection is realized by picking out the useful information and utilizing the features.

Step 503, the business server searches the business card information of the participating user according to the participating face data.

The user data of the participated users can be stored in the service server in advance, and the identities of the participated users are identified from the participated face data in the video conference process, so that the participated user data are searched, and the business card information of the participated user data is generated.

In one embodiment of the present invention, step 503 may include the following sub-steps:

and a substep S11, matching the conference-participating face data with target face data pre-entered by the conference-participating user.

And a substep S12, when the matching is successful, extracting the business card information corresponding to the target face data from a preset business card database.

By applying the embodiment of the invention, the face data of the participated users and the user information (such as name, area, position and the like) of the participated users can be input into the business service in advance, and the face data is used as the target face data to establish a mapping relation with the user information and is stored in the business card database.

In the process of the video conference, the service server calculates the similarity between the detected participated face data and the target face data, and if the similarity is higher than a certain threshold value, the two data can be considered to be successfully matched.

And then, extracting user information corresponding to the successfully matched target face data from the business card database to generate business card information.

In one embodiment of the present invention, the sub-step S12 further includes the following sub-steps:

and a substep S121, determining the position of the conference-participating face data of the conference-participating user in the conference-participating video data.

In a conference room, different sitting positions are arranged for different conference users, when technicians arrange the conference room, the technicians adopt a camera to preview, the previewed image data is divided into a plurality of grids, and the grids at the positions are calibrated.

Therefore, the participated video data is divided into a plurality of grids, the grids where the participated face data of the participated users are located are determined, and the positions of the participated users are determined based on the grids.

And a substep S122, determining the business card type of the business card information according to the position.

And a substep S123 of extracting user data corresponding to the target face data in a preset business card database according to the business card type.

And a substep S124, generating business card information of the participating users by adopting the user data.

For different sitting positions, different requirements are made on the name card information, such as a chairman desk, an auditorium, a speech seat and the like, for example, the auditorium displays a name, and the chairman desk displays a name, an area, a position and the like, so that corresponding name card types can be set for different sitting positions in advance.

And extracting user data required by the name card type from the user data corresponding to the target face data in the name card database, thereby generating name card information of the participating users.

Step 504, the business server sends the business card information to the video network terminal through the video network server, and then the business card information is forwarded to the business card display for display.

After searching the business card information of the participated users, the business server can send the business card information to the video networking server.

The video network server returns the business card information to the video network terminal according to the downlink communication link configured for the video network terminal, the video network terminal sends the business card information to the business card display, and the business card display displays the business card information.

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 a target terminal (such as a video network terminal) according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: and informing the switching equipment related to the downlink communication link of the current service to allocate the table.

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.
