The unified video platform adopts a menu type configuration table mode to replace the traditional complex application programming, can realize complex application by using very few codes, and realizes infinite new service innovation.

Networking of the video network is as follows:

the video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network.

As shown in fig. 1, the video network is divided into an access network and a metropolitan network.

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a 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 a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.

Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.

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.

First conference data and the like of each first participant terminal 504 of the first video networking audio/video conference are all sent to the first conference server 501. The first conference data may be speech data of each first participant terminal 504 or the first conference server 501 in the first video-networking audio-video conference, and the like. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, since the first conference server 501 and each first participant terminal 504 support the same video networking protocol, the first conference data also supports the video networking protocol.

For example, for the above example, the first conferencing server 501 and each of the first participant terminals 504 each support a 16-bit video networking protocol. Then the first conference data also supports the 16-bit video networking protocol.

In the embodiment of the present invention, the first conference server identifier and the second conference server identifier may be information capable of distinguishing or characterizing the first conference server and the second conference server, respectively. For example, the first conferencing server identification may be the MAC address of the first conferencing server 501. The second conference server identification may be the MAC address of the second conference server 502.

In an embodiment of the present invention, the first conference data includes: a first conference server identification and a second conference server identification.

Step 602: and the transit terminal receives the first conference data sent by the first conference server based on the video networking protocol interface corresponding to the first conference server identifier.

In this embodiment of the present invention, the relay terminal 503 may receive the first conference data sent by the first conference server based on the video networking protocol interface corresponding to the identifier of the first conference server.

Specifically, the transit terminal 503 may perform data interaction with the first conference server 501 based on the video networking protocol interface corresponding to the identifier of the first conference server. Then, the transit terminal 503 may receive the first conference data sent by the first conference server based on the video networking protocol interface corresponding to the first conference server identifier.

For example, referring to the above example, if the first conferencing server 501 supports a 16-bit video networking protocol. Then, the transit terminal 503 may receive the first conference data supporting the 16-bit internet protocol, which is sent by the first conference server 501, based on the 16-bit internet protocol interface.

Step 603: under the condition that the video networking protocols corresponding to the first conference server identification and the second conference server identification are different, the transfer terminal converts the first conference data into second conference data supporting a second video networking audio and video conference; and the second video networking audio and video conference is held by the second conference server and each second participating terminal.

In this embodiment of the present invention, the relay terminal 503 acquires the video networking protocol corresponding to the first server identifier. The relay terminal 503 also obtains the video networking protocol corresponding to the second server identifier. The relay terminal 503 compares the two video networking protocols, and if the two protocols are different, it indicates that: the first conference data is different from the video networking protocol corresponding to the second server identification, and the first conference data cannot be normally received and played in the second video networking audio and video conference corresponding to the second server identification. Then, the transfer terminal converts the first conference data into second conference data supporting a second video networking audio/video conference; the second video networking audio and video conference is held by the aforementioned second conference server 502 and each second participating terminal 505.

The second video networking audio and video conference is held by the aforementioned second conference server 502 and each second participating terminal 505. Description of the drawings: the second video networking audio and video conference only supports the receiving and playing of video networking protocol data corresponding to the second conference server identification. And under the condition that the video networking protocols corresponding to the first conference server identification and the second conference server identification are different, the video networking protocol supported by the second video networking audio and video conference is the same as the video networking protocol corresponding to the second conference server identification, which indicates that the video networking protocol supported by the first conference data is different from the video networking protocol supported by the second video networking audio and video conference. In order to realize normal receiving, playing and the like of the first conference data in the first video networking audio/video conference and the second video networking audio/video conference, the relay terminal 503 converts the first conference data into second conference data supporting the second video networking audio/video conference.

In this embodiment of the present invention, optionally, the converting, by the relay terminal, the first conference data into second conference data that supports a second video networking audio/video conference may include: the transfer terminal acquires a target video networking protocol corresponding to the second conference server identifier; and the transfer terminal converts the first conference data into second conference data supporting the target video networking protocol.

Specifically, under the condition that the video networking protocols corresponding to the first conference server identifier and the second conference server identifier are different, the relay terminal 503 may obtain the target video networking protocol corresponding to the second conference server identifier. And the video networking protocol supported by the second video networking audio/video conference is the same as the video networking protocol corresponding to the second conference server identifier. Then, the transit terminal 503 may convert the first conference data into second conference data supporting the target video networking protocol.

For example, referring to the above example, if the first conferencing server identifies the corresponding video networking protocol as a 16-bit video networking protocol. The second conference server identifies the corresponding video networking protocol as a 64-bit video networking protocol. The two corresponding video networking protocols are different, and the target video networking protocol corresponding to the second conference server identifier acquired by the relay terminal 503 is the 64-bit video networking protocol. The transit terminal 503 may convert the first conference data into second conference data supporting the target internet protocol 64-bit internet protocol.

In the embodiment of the present invention, optionally, in a case that the video networking protocols corresponding to the first conference server identifier and the second conference server identifier are the same, it is described that the video networking protocols corresponding to the first conference server identifier and the second conference server identifier are the same. If the first conference data does not need to be converted, and the protocol supported by the first conference data is the same as that supported by the second video networking audio/video conference, the relay terminal 503 can directly send the first conference data to the second video networking audio/video conference through the second conference server 502; the second video networking audio and video conference is held by the second conference server 502 and each second participant terminal 505. The first conference data is played as speech data in each of the second participant terminals 505.

For example, referring to the above example, if the first conferencing server identifies the corresponding video networking protocol as a 16-bit video networking protocol. The second conference server identifies the corresponding video networking protocol as a 16-bit video networking protocol. The corresponding video networking protocols of the two are the same, and the relay terminal 503 can directly send the first conference data to the second video networking audio/video conference through the second conference server 502. The second video networking audio and video conference is held by the second conference server 502 and each second participant terminal 505. The first conference data is played as speech data in each of the second participant terminals 505.

Step 604: the transfer terminal forwards the second conference data to the second video networking audio and video conference through the second conference server based on the video networking protocol interface corresponding to the second conference server identifier; and playing the second conference data as speaking data in each second participant terminal.

And the intercommunication of a first video networking audio and video conference and a second video networking audio and video conference which support different video networking protocols is realized.

For example, referring to the above example, if the first conferencing server identifies the corresponding video networking protocol as a 16-bit video networking protocol. The second conference server identifies the corresponding video networking protocol as a 64-bit video networking protocol. The two corresponding video networking protocols are different, and the relay terminal 503 converts the first conference data into second conference data supporting a 64-bit video networking protocol. The relay terminal 503 sends the second conference data supporting the 64-bit video networking protocol to the second video networking audio/video conference through the second conference server 502 based on the 64-bit video networking protocol interface. The second conference data supporting the 64-bit video networking protocol is played as the speech data in each second participant terminal 505. And the intercommunication of a first video networking audio and video conference supporting a 16-bit video networking protocol and a second video networking audio and video conference supporting a 64-bit video networking protocol is realized.

In the embodiment of the present invention, the relay terminal 503 forwards the second conference data to each second video networking audio/video conference through the second conference server 502 based on the video networking protocol interface corresponding to the second conference server identifier. The method specifically comprises the following steps: the relay terminal 503 sends the second conference data to the second conference server 502 based on the video networking protocol interface corresponding to the second conference server identifier. The second conference server 502 then forwards the second conference data to the respective second participant terminals 505. The second conference data is normally played in each second participant terminal 505. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, under the condition that the video networking protocols corresponding to the first conference server identifier and the second conference server identifier are different, the relay terminal 503 converts the first conference data into second conference data supporting a second video networking audio/video conference; the second video networking audio and video conference is held by the second conference server 502 and each second participant terminal 505. The relay terminal 503 may forward the second conference data to the second video networking audio/video conference through the second conference server 502 based on the video networking protocol interface corresponding to the second conference server identifier; the second conference data is played back as speech data in each of the second participant terminals 505. Meanwhile, the first conference data is converted once through the relay terminal 503, and then the first conference data is played in the plurality of second participant terminals 505 supporting different protocols, and conversion does not need to be performed on each second participant terminal 505, so that the efficiency of intercommunication of the participant terminals supporting different protocols is improved.
