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.

By applying the embodiment of the invention, the video networking terminal can be accessed to the conference created by the Internet terminal of the H323 protocol in a calling mode by adding the URL address resolution module on the protocol conversion server.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for accessing a conference by a video network terminal according to the present invention is shown, where the method is applied to a video network, where the video network includes a video network device and a collaboration server, and the method may specifically include the following steps:

step 501, the video networking device sends a first call request to the protocol conversion server.

In a preferred embodiment of the present invention, the video network device may comprise a video network terminal and a video network server, and the step 501 may comprise the following sub-steps:

In practical application, when the video networking device of the intranet starts to call and access a certain conference in the internet, the video networking device firstly sends a video networking call request to the coordination server. The H323 conference uses an IP address on the network as an IP address of the internet device of the H323 conference, creates a plurality of conference rooms on the internet device, and assigns a conference room number to each conference room.

Specifically, when the terminal of the video network starts to call a conference created on the internet device, the terminal of the video network sends a call request 8e01callRequest to the server of the video network, and the server of the video network converts the call request 8e01callRequest into a call request 8e02callRequest of the video network and then sends the call request to the protocol conversion server.

Step 502, the coordination server converts the first call request into a second call request.

As an example, the internet protocols may include the H323 protocol, which is a TCP/IP layer based protocol, and the H323 protocol cluster specifies components, protocols, and procedures for providing multimedia communications over packet-switching based networks, including primarily IP networks.

The H323 protocol defines a total of four components: terminals, gateways, gatekeepers and multipoint control units, the H323 protocol may support point-to-point or point-to-multipoint communication of audio, video and data.

The h.323 protocol cluster includes h.225.0 for call setup, h.245 for control, h.332 for large conference, and h.450.x for supplementary service, etc., and the h.323 protocol includes 3 signaling control channels: RAS signaling channels, call signaling channels, and h.245 control channels. The coordination of 3 channels allows h.323 calls to proceed.

In the embodiment of the invention, a URL address resolution module is arranged on the protocol conversion server. The protocol conversion server converts the call request sent by the video networking equipment into a call request of H225.0 in an H323 protocol cluster and sends the call request to the URL address resolution module.

Step 503, the coordination server analyzes the second call request to obtain a call analysis result.

After the call request is sent to the URL address analysis module by the server, the URL address analysis module analyzes the call request and extracts effective data.

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

and the cooperative conversion server determines the Internet equipment needing to be connected to the Internet according to the prefix.

Based on the address translation role of the collaboration server, the embodiment of the invention can access to internet conferences, because the conferences are created on an internet device, and each conference has a conference room number (conference number) as the conference identifier.

When the video network terminal wants to access a certain conference, a conference number can be input in an address bar, then a '@' symbol is added as a connector, and the IP address of the Internet equipment is connected behind the '@', so that the video network terminal can be accurately accessed into a certain conference. In addition, the embodiment of the invention calls the conference accessed to the internet directly through the video network terminal, so that the video network terminal is added with 60 as a prefix at the forefront of the call rule based on the video network terminal to indicate that the video network terminal is accessed to the conference accessed to the internet. In summary, the request rule of the call in the embodiment of the present invention is "60+ conference number + @ + Pexip-MCUIP".

Thus, if the prefix "60" is extracted from the call request, it is stated that it is in a meeting that requires connection to the internet. Of course, in practical applications, other prefixes than "60" may be used to indicate that the video networking terminal accesses to the internet in the conference, and the embodiment of the present invention is not limited to this.

In one example, after the collaboration server sends the call request to the URL address resolution module, the URL address resolution module resolves the call request. First the module identifies the prefix 60 and confirms that the video networking device is using a conference call on the internet device. The URL address resolution module then identifies the conference number in the H225 request rule, then finds the conference on the internet device, finally confirms the @ symbol, knowing that the @ symbol is followed by the IP address (destination address) of the called internet device, and the URL address resolution module sends the call request to the internet device.

And step 504, the coordination server sends the second call request to an internet terminal according to the call analysis result.

In a specific implementation, the internet terminal comprises Pexip-MCU and Pexip. The Pexip is a video conference soft terminal supporting the H323 protocol, and the Pexip-MCU is conference equipment capable of creating the H323 protocol.

In a preferred embodiment of the present invention, the step 504 may include the following sub-steps:

In the embodiment of the invention, the protocol conversion server can be connected to the corresponding internet equipment in the conference according to the IP address (target address) and the conference room number in the call request.

And 505, when the internet terminal agrees to the video networking device to access the conference, sending a first agreement response message to the coordination server.

Step 506, the coordination server converts the first agreement response message into a second agreement response message and sends the second agreement response message to the video network device.

If the Internet equipment agrees to the video networking terminal to access the conference, replying an agreement response message to the protocol conversion server, and the protocol conversion server converts the agreement response message of the protocol conversion server into a video networking protocol and feeds the agreement response message back to the video networking equipment.

Step 507, the video networking device generates an access confirmation message for the second agreement response message, and sends the access confirmation message to the coordination server.

After receiving the agreement response message, the video network terminal successfully accesses the conference of the internet, then sends an access confirmation message to the protocol conversion server, and the protocol conversion server converts the access confirmation message into an access confirmation message of an H225 protocol and sends the access confirmation message to the internet equipment, so that the video network terminal can access the conference of the H323 protocol with a designated conference number.

In practical application, if the video network terminal can quit the conference of the internet. Specifically, in a preferred embodiment of the present invention, the process of the video network terminal exiting the conference of the internet is as follows:

In a preferred embodiment of the present invention, the method may further comprise the steps of:

the protocol conversion server creates a virtual video network terminal;

Since the Internet is communicated by TCP/IP (Transmission Control Protocol/Internet Protocol, also known as network communication Protocol), it cannot be directly connected to the video network terminal. When a video network terminal wants to access an internet external resource, such as a video conference or other services, information for accessing the internet external resource is first sent to a protocol conversion server.

The internet external resources are internet devices for collecting information through a TCP/IP Protocol, and include all terminals supporting a standard H323 Protocol and an SIP (Session Initiation Protocol). The SIP is a multimedia communication protocol established by IETF (Internet Engineering Task Force).

After the environment is established, the protocol conversion server is started, and after configuration is finished, the protocol conversion server virtualizes some video networking virtual terminals. A plurality of virtual terminals are arranged in the cooperation server, the virtual terminals have the same functions as the video networking terminals, and can complete various tasks which can be completed by the video networking terminals.

The virtual terminals all have a five-digit video networking number, because the embodiment of the invention calls a conference, each video networking virtual terminal is in one-to-one correspondence with a conference room number, the video networking terminal calls the five-digit video networking number on the surface, actually calls the address of the conference room of the video networking number bound in the protocol conversion server, the IP address of the Internet terminal is called in the signaling, and then a URL address resolution module is used for resolving a specific conference room of which the terminal is accessed to a known conference number on the Internet terminal.

In order to enable those skilled in the art to better understand the process of accessing the video networking terminal (video networking STB terminal, 8168 polar light) to the internet terminal (Pexip-MCU, H323MCU) conference through the collaboration server according to the embodiment of the present invention, the specific architecture can be shown with reference to fig. 6 and fig. 7. Wherein, the H323 cooperative gateway refers to a cooperative server.

Referring to fig. 8, there is shown a flow chart of a video networking terminal call access H323 conference of the present invention, in which 8704close decoder and 8704close encode in fig. 8 are instructions to turn on and off the codec of the audio and video. The specific process is as follows:

(1) firstly, an H323 cooperative gateway is configured, and a virtual video network terminal generated by the H323 cooperative gateway is enabled to access the network. 8168 polar light then starts calling the conference created on the Pexip-MCU. 8168 the polar light sends the call request 8e01callRequest to the server of the view network, and the server of the view network sends the call request 8e01callRequest to the H323 protocol conversion gateway after converting the call request 8e02callRequest into the call request of the view network.

(2) The H323 protocol conversion gateway converts the video internet call request 8e02callRequest into a call request Cs in the H225 call process: and after setup, sending the result to a URL address resolution module of the H323 cooperative gateway. The call request contains the conference number + @ + Pexip-MCUip.

(3) The URL address resolution module receives a call request Cs: after setup, it is first indicated by the conference number in front of the @ symbol that the H323 coordinating gateway is to call a specific designated conference that has been created on the Pexip-MCU.

(4) Then, after the IP address according to the @ symbol, it indicates that the call request Cs: setup is sent to, and Cs: the setup request is sent to the corresponding Pexip-MCU.

(5) The called Pexip-MCU, after receiving the request, replies with an agreement response message Cs: and (4) calling, Cs: alerting, Cs: connect, sending to the H323 cooperative gateway, and converting the message according to the H323 protocol into an agreement response message 8e01 calling response of the video networking protocol by the H323 cooperative gateway, and sending the agreement response message to the video networking server.

(6) The video network server converts the consent response message 8e01callRespond into a consent response message 8e02callRespond and sends the consent response message to 8168 aurora, and the 8168 aurora sends an access confirmation message 8e01 callResponddack to the video network server to confirm connection, which indicates that the conference created by the Pexip-MCU which has accessed the Internet is in progress.

(7) Until the call is successfully established, operations such as capability negotiation and master-slave decision can be performed later, which is not described herein.

(8) When 8168 extremely intensely wants to exit the H323 conference, the internet of view hang-up request 8e01 hang-up is sent to the internet of view server, and the internet of view server converts the internet of view hang-up request 8e01 hang-up into an internet of view hang-up request 8e02 hang-up and sends the converted request to the H323 cooperative gateway.

(9) The H323 cooperative gateway converts the video networking hang-up request 8e02hangup into a video networking hang-up request Cs in the process of an H225 call: and a releaseComplete module for analyzing the URL address of the H323 protocol gateway. The video network hang-up request comprises a conference number + @ + Pexip-MCUip.

(10) Likewise, after receiving the request, the URL address resolution module first indicates that the H323 negotiation gateway is to exit the specific specified conference that has been created on the Pexip-MCU according to the conference number in front of the @ symbol. Then, based on the IP address following the @ sign, the destination address to which the request is to be sent is indicated, and then the video network hang-up request Cs: the releaseComplete is sent to Pexip-MCU.

(11) After receiving the hang-up request, the Pexip-MCU replies a hang-up confirmation message Cs: and the releaseCompleteAck is sent to the H323 cooperative gateway, and the H323 cooperative gateway converts the H323 protocol into 8e01 handoff of the video networking protocol and sends the handoff to the video networking server.

(12) The visual networking server converts 8e01hangup into 8e02hangup and sends the 8e02hangup to the 8168 aurora terminal, and the 8168 aurora sends 8e01 hangprespondack to the visual networking server to confirm hang-up, which indicates that the visual networking server exits from the conference created by the Internet Pexip-MCU.

The embodiment of the invention can achieve the aim of accessing the conference by calling a successful conference established on the H323MCU by using the video network terminal equipment in a unit local area network through the URL address analysis module of the protocol conversion server, thereby greatly improving the requirement of interconnection and intercommunication between the video network and the Internet and benefiting from the protocol conversion function of the H323 protocol conversion server.
