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, one of the core concepts of the embodiment of the invention is provided, the parent-child hierarchy relationship is established for the conference management equipment in each region according to the protocol of the video network, and the parent conference management equipment is adopted to actively acquire the video network conference data of the child conference management equipment, or the child conference management equipment actively reports the video network conference data to the parent conference management equipment, so that the parent conference management equipment can view the video network conference data of the whole region.

In practical application, the video network can be divided into a plurality of local video networks according to factors such as regions and the like.

The local area video network is a computer communication network formed by connecting various video network terminals, video network servers, conference management equipment, peripheral equipment and the like within a local geographic range (such as Beijing area, Xinjiang area and the like).

In the video conference of the video network, as shown in fig. 5, in the video network 500, a video network server 510, a plurality of video network terminals 520, and a conference management device 530 are disposed.

The video network server 510 controls a plurality of video network terminals 520 and the conference management device 530 to access the video network 500 according to the video network protocol V2V, and after the access is successful, the video network server 510 maintains heartbeat with the plurality of video network terminals 520 and the conference management device 530 respectively, so that the video network server 510 connects the plurality of video network terminals 520 and the conference management device 530.

The video network terminal 520 may be a set-top box (STB), which is generally called a set-top box or set-top box, and is a device for connecting a tv set and an external signal source, and converting a compressed digital signal into tv content and displaying the tv content on the tv set.

Generally, the video network terminals 520 may be connected to other devices 542, for example, the device 542 may be at least one camera and at least one microphone for collecting at least one video data and at least one audio data, and the device 542 may also be a television for playing the video data and the audio data.

In this embodiment of the present invention, a plurality of video networking terminals 520 may be used to perform a video conference, the conference control client 541 may connect with the video networking terminals 520 through a TCP protocol, the video networking terminals 520 connected with the conference control client 541 are video networking chairman terminals serving as a chairman of the conference, and the conference control client 541 may communicate with the video networking server 510 and the conference management device 530 through the video networking terminals 520 serving as the chairman of the conference to control the video conference, such as switching speakers, switching video walls, controlling playing and monitoring, and the like.

The conference management device 530 may manage video conferencing for the video network, e.g., allocating resources, etc.

Before the video conference is started, the conference control client 541 can make a reservation to the conference management apparatus 530 through the video network terminal 520 as a chairman of the conference network, and the conference management apparatus 530 records conference reservation data.

In a specific implementation, the conference reservation data includes at least one of:

the number of the video network terminals as the chairman of the conference, the number of the participants, the number of the video network terminals, the start time of the video conference, the end time of the video conference and the grade of the video conference.

The level of the video conference can be used to assist technicians in auditing the video conference and allocating resources, for example, the level of the video conference of provincial staff is higher than that of urban staff, and the technicians can allocate more resources (such as bandwidth and equipment) to the video conference of provincial staff.

And the related technical personnel carry out auditing based on the appointed conference appointment data, and can carry out the video conference if the auditing is passed.

In video networking, a video conference may be a bundle of multiple live broadcasts.

For live interactive processes, there are generally the following ways:

1. initiating live broadcast

Live broadcast data is also broadcast data

The method comprises the steps that a live video network terminal (set top box) sends an application command, a video network server automatically distributes a path of broadcast data after receiving the application, sends a coding and decoding command to the video network terminal (set top box), and simultaneously commands an upper-layer switch of the live video network terminal (set top box) to open a path of the broadcast data. The live video network terminal (set-top box) can watch the broadcast initiated by the live video network terminal, and the initiator is also a watching party.

For an internet of view terminal, a packet of video data may be encapsulated for transmission by the 2000 specification of the following internet of view protocol:

for an internet of view terminal, packets of audio data may be encapsulated for transmission by the 2001 specification of the internet of view protocol as follows:

2. watching live broadcast

The watching video network terminal (set-top box) sends an application command, and the command comprises the number of the live broadcasting initiating party. After receiving the application, the video network server inquires whether the video network terminal (set-top box) initiating the live broadcast is connected to the network or not and whether the live broadcast is initiated or not. If the condition is not satisfied, informing the watching terminal (set top box) of the watching video network that the watching is failed.

If the conditions are met, the video network server needs to find a path between a video network terminal (set top box) initiating the live broadcast and a video network terminal (set top box) watching, a path of all switches between the live video network terminal (set top box) and the video network terminal (set top box) watching for the broadcast data is opened, and simultaneously a decoding command is sent to the video network terminal (set top box) watching, so that the video network terminal (set top box) watching can watch the live broadcast.

In the process of the video conference, the conference management device 630 records the relevant information of the video conference, and generates conference recording data.

In a particular implementation, the meeting record data includes at least one of:

the number of the video network terminals as the chairman of the conference, the number of the participants, the number of the video network terminals, the start time of the video conference, the end time of the video conference, the location of the video conference (based on the position of the chairman), and the grade of the video conference.

Referring to fig. 6, a flowchart illustrating steps of a method for synchronizing video networking conference data according to an embodiment of the present invention is shown, where the method may be applied to a video networking, and specifically may include the following steps:

step 601, the child conference management device logs in the parent conference management device.

Step 602, when the child conference management device successfully logs in, writing the device information of the child conference management device into the parent conference management device.

Step 603, the child conference management device stores the device information of the parent conference management device.

In the embodiment of the invention, the child conference management device and the parent conference management device are conference management devices which belong to different local area video networks, and the parent-child relationship is relative to the management of video network conference data.

For example, a conference management device disposed in beijing is defined as a parent conference management device, and conference management devices disposed in respective cities are defined as child conference management devices.

Initially, the user may input device information of the parent conference management device and the child conference management device in the child conference management device, where the device information may include a device address and device account information (e.g., an account, a password, etc.).

Due to the regionality of the local area video network, the child conference management device and the parent conference management device can communicate through telnet (remote terminal protocol) of the IP network.

In a specific implementation, the child conference management device may access a device address (e.g., an IP address) of the parent conference management device through an IP network, and remotely establish a TCP (Transmission Control Protocol) connection with the parent conference management device.

After the TCP connection is successfully established, the child conference management device transmits the account information input locally to a remote parent conference management device (IP packet) in nvt (net Virtual terminal) format for login.

And if the child conference management equipment fails to log in the parent conference management equipment, ending the operation.

If the child conference management device successfully logs in the parent conference management device, the child conference management device may write the device information of the child conference management device into the specified position of the database in the parent conference management device, and at the same time, write the device information of the parent conference management device into the specified position of the local database of the child conference management device, thereby implementing registration and establishing a parent-child relationship.

Referring to fig. 7, a flowchart illustrating steps of another video network conference data synchronization method according to an embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:

in step 701, a parent conference management device logs in a child conference management device.

In the embodiment of the present invention, the parent conference management device may log in the child conference management device and perform synchronization of video networking conference data with the child conference management device under the conditions of receiving a synchronization instruction triggered by a user, a specified time (for example, 2 am every day), and the like.

In one embodiment of the present invention, step 701 may include the following sub-steps:

and a sub-step S11 of traversing the device information of the sub-conference management device.

A substep S12 of accessing the device address to connect the child conference management device;

and a substep S13, logging in the sub-conference management device by using the device account information.

In an embodiment of the present invention, the parent conference management device may traverse the device information of each registered child conference management device in a local database.

The device information of the sub-conference management device includes a device address (such as an IP address) and device account information (such as an account and a password).

The parent conference management device may access a device address (e.g., IP address) of the child conference management device via the IP network to remotely establish a TCP connection with the child conference management device.

After the TCP connection is successfully established, the parent conference management device transmits the account information of the child conference management device to a remote child conference management device (IP data packet) in an NVT format for login.

Step 702, when the parent conference management device successfully logs in, acquiring video networking conference data from the child conference management device.

And if the parent conference management equipment fails to log in the child conference management equipment, continuing to log in the next child conference management equipment.

If the parent conference management device successfully logs in the child conference management device, the video networking conference data generated by the child conference management device can be extracted from the position specified by the database in the child conference management device, and the synchronization processing is waited to be carried out.

The video networking conference data can comprise conference reservation data and conference recording data.

And step 703, the parent conference management device performs synchronization processing on the video networking conference data.

After the parent conference management device currently acquires the video networking conference data from the child conference management device, the parent conference management device may perform a synchronization operation.

Since the parent conference management device has previously stored the historical video networking conference data of the child conference management device, for this child conference management device, the current video networking conference data can be compared with the historical video networking conference data:

and if the current video networking conference data is the same as the historical video networking conference data, discarding the current video networking conference data.

And if the current video networking conference data does not have the corresponding historical video networking conference data, namely the current video networking conference data is the video networking data newly added by the sub-conference management equipment, storing the current video networking conference data.

And if the historical video networking conference data does not have the corresponding current video networking conference data, namely the historical video networking conference data is deleted by the sub-conference management equipment, deleting the historical video networking conference data.

Of course, the above synchronization process is only an example, and when implementing the embodiment of the present invention, other synchronization processes may be set according to actual situations, for example, the current video network conference is entirely written into a local database, and the like, which is not limited in the embodiment of the present invention. In addition, besides the above synchronization process, a person skilled in the art may also use other synchronization processes according to actual needs, and the embodiment of the present invention is not limited thereto.

And after the sub-conference management equipment is synchronized, continuing to log in the next sub-conference management equipment for synchronization until all the sub-conference management equipment is traversed.

Referring to fig. 8, a flowchart illustrating steps of a further method for synchronizing video networking conference data according to an embodiment of the present invention is shown, where the method may be applied to a video networking, and specifically may include the following steps:

step 801, when detecting that the video networking conference data is changed, the child conference management device logs in the parent conference management device.

In the embodiment of the invention, the child conference management device can log in the parent conference management device under the condition that the video networking conference is changed, and synchronize video networking conference data with the parent conference management device.

In one embodiment of the present invention, step 801 may include the following sub-steps:

and a sub-step S21 of inquiring device information of the parent conference management device.

Sub-step S22, accessing the device address to connect to the parent conference management device.

And a substep S23, logging in the parent conference management device by using the device account information.

In the embodiment of the present invention, the child conference management device may query the local database for the device information of the registered parent conference management device.

The device information of the parent conference management device includes a device address (such as an IP address) and device account information (such as an account and a password).

The child conference management device may access a device address (e.g., IP address) of the parent conference management device via an IP network to remotely establish a TCP connection with the parent conference management device.

After the TCP connection is successfully established, the child conference management device transmits the account information of the parent conference management device to a remote parent conference management device (IP data packet) in an NVT format for login.

Step 802, when the child conference management device successfully logs in, the changed video networking conference data is synchronized in the parent conference management device.

And if the child conference management equipment fails to log in the parent conference management equipment, finishing the synchronous operation.

If the child conference management device successfully logs in the parent conference management device, the video networking conference data changed by the child conference management device can be synchronously processed at the position specified by the database in the parent conference management device.

In a specific implementation, the change of the video networking conference data can include three situations, namely addition, modification and deletion.

And if the newly added video networking conference data is added, storing the newly added video networking conference data to the father conference management equipment.

And if the video networking conference data is modified, modifying the video networking conference data stored in the parent conference management equipment.

In the embodiment of the invention, the sub-conference management equipment logs in the parent conference management equipment when detecting the change of the video networking conference data, and synchronously processes the changed video networking conference data in the parent conference management equipment when the logging is successful, and the sub-conference management equipment actively performs synchronous processing on the changed video networking conference data, thereby ensuring the timeliness of the video networking conference data.
