The video networking is an important milestone for network development, is a real-time network, can realize real-time transmission of high-definition videos, and pushes numerous internet applications to high-definition videos, and the high definition faces.

The video networking adopts a real-time high-definition video exchange technology, and can integrate all required services such as high-definition video conference, video monitoring, intelligent monitoring analysis, emergency command, digital broadcast television, delay television, network teaching, live broadcast, VOD on demand, television mail, personal record (PVR), intranet (self-processing) channel, intelligent video playing control, information release and other tens of services into one system platform, and realize high-definition quality video playing through television or computer.

For a better understanding of embodiments of the present invention, the following description of the video networking is presented to one skilled in the art:

the partial techniques applied by the video networking are as follows:

Network technology (Network Technology)

The network technology innovation of the internet of vision improves on the traditional Ethernet (Ethernet) to face the potentially huge first video traffic on the network. Unlike pure network packet switching (PACKET SWITCHING) or network circuit switching (Circuit Switching), the technology of video networking employs PACKET SWITCHING to meet Streaming requirements. The video networking technology has the flexibility, simplicity and low price of packet switching, and simultaneously has the quality and the safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.

Exchange technology (SWITCHING TECHNOLOGY)

The video network adopts the two advantages of the asynchronization and the packet switching of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, has full-network end-to-end seamless connection, and is directly connected with the user terminal to directly bear the IP data packet. The user data does not need any format conversion in the whole network. The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.

Server technology (Server Technology)

The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.

Accumulator technology (Storage Technology)

The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system for adapting to the ultra-large capacity and ultra-large flow media content, the program information in the server instruction is mapped to a specific hard disk space, the media content does not pass through the server any more, the media content is instantly and directly delivered to a user terminal, and the waiting time of the user is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.

Network security technology (Network Security Technology)

The structural design of the video networking thoroughly structurally solves the network security problem puzzling the Internet by means of independent permission of each service, complete isolation of equipment and user data and the like, generally does not need antivirus programs or firewalls, eliminates attacks of hackers and viruses, and provides a structural carefree security network for users.

Service innovation technology (Service Innovation Technology)

The unified video platform fuses services with transmissions, whether a single user, private network users or a network aggregate, but automatically connects at a time. The user terminal, the set top box or the PC is directly connected to the unified video platform, so that various multimedia video services are obtained. The unified video platform adopts a menu type table allocation mode to replace the traditional complex application programming, and can realize complex application by using very few codes, thereby realizing 'infinite' new business innovation.

Networking of the video networking is as follows:

The video networking is a centrally controlled network structure, which may be of the tree network, star network, ring network, etc., but on the basis of this there is a need for a centralized control node in the network to control the whole network.

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

The devices of the access network part can be mainly divided into 3 classes: node server, access switch, terminal (including various set-top boxes, code boards, memories, etc.). The node server is connected with an access switch, which can be connected with a plurality of terminals and can be connected with an Ethernet.

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

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

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

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

The access network part can be vividly called as a unified video platform (part in a dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform can be interconnected and intercommunicated through metropolitan area and wide area video networking.

2. View networking data 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 data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), 256 possibilities are at most provided, the second byte to the sixth byte are metropolitan area network addresses, and the seventh and eighth bytes are access network addresses;

the Source Address (SA) is also composed of 8 bytes (bytes), defined identically to the Destination Address (DA);

The reserved bytes consist of 2 bytes;

the payload portion has different lengths according to the types of the different datagrams, and is 64 bytes if it is various protocol packets, and 32+1024=1056 bytes if it is a unicast packet, and is of course not limited to the above 2 types;

The CRC consists of 4 bytes and its calculation method follows the standard ethernet CRC algorithm.

2.2 Metropolitan area network packet definition

The topology of the metropolitan area network is a pattern, there may be 2 or even more than 2 connections between two devices, i.e. there may be more than 2 connections between node switches and node servers, node switches and node switches, node switches and node servers. However, the metropolitan area network address of the metropolitan area network device is unique, and in order to accurately describe the connection relationship between metropolitan area network devices, parameters are introduced in the embodiment of the present invention: a tag to uniquely describe a metropolitan area network device.

In this specification, the definition of label is similar to that of MPLS (Multi-Protocol Label Switch, multiprotocol label switching), and assuming that there are two connections between device a and device B, there are 2 labels for packets from device a to device B, and 2 labels for packets from device B to device a. The label is split into label and label out, and assuming that the label (in label) of the packet entering the device a is 0x0000, the label (out label) of the packet when leaving the device a may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, that is, the address allocation and label allocation of the metropolitan area network are all led by the metropolitan area server, the node switch and the node server are all passively executed, which is different from the label allocation of the MPLS, which is the result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metropolitan area network mainly includes the following parts:

DA

SA

Reserved

Label (Label)

Payload

CRC

I.e. Destination Address (DA), source Address (SA), reserved bytes (Reserved), labels, payload (PDU), CRC. Wherein the format of the tag may be defined with reference to the following: the tag is 32 bits, with the high 16bit reservation, with only the low 16bit, and its position is between the reserved bytes and payload of the packet.

Along with expansion of video networking service, an internet terminal in the internet needs to call a video networking terminal in the video networking to perform video point-to-point video session, but when the video networking terminal performs video session, a video session protocol set in the video networking is generally used, and when the internet terminal performs video session, a video session protocol in the internet is generally used. For example, SIP protocol or H323 protocol, and when a video session is performed, the video session protocols used by both parties need to be the same to be performed successfully. Therefore, the internet terminal cannot initiate a video call request to the video networking terminal, so that the problem that the internet terminal cannot conduct video session with the video networking terminal is caused.

In view of this, the present invention proposes the core concept of the present invention based on the characteristics of the above-mentioned internet of vision: and configuring a cooperative server capable of communicating with the two terminals between the video networking terminal and the Internet terminal, receiving a call request sent by the Internet terminal by using the cooperative server, and converting the call request into a target call request capable of adapting to the video networking terminal according to the address format of a call address in the call request, thereby solving the problem that video session cannot be successfully carried out due to different video call protocols between the Internet terminal and the video networking terminal.

Referring to fig. 5, a communication architecture diagram of a video session establishment method according to an embodiment of the present invention is shown, and as shown in fig. 5, the communication architecture diagram includes a collaboration server, an internet terminal, and a video networking terminal. The internet terminal is located in the internet, and the video networking terminal is located in the video networking.

The internet terminal can be intelligent equipment such as a smart phone and a tablet personal computer, and the video networking terminal can be a set top box special for video networking data transmission in the video networking.

In this embodiment, the co-rotation server may pre-configure an internet communication protocol adapted to the internet network and a video networking communication protocol adapted to the video networking network, so that the co-rotation server may communicate with the internet terminal based on the internet protocol and communicate with the video networking terminal based on the video networking protocol.

The video session establishment method of the present embodiment is explained in detail from the cooperative server side in conjunction with the communication architecture shown in fig. 5.

Referring to fig. 6, a flowchart illustrating steps of a video session establishment method implemented by a corotation server side according to the present embodiment may specifically include the following steps:

step S601: and receiving a call request sent by the Internet terminal, wherein the call request carries a call address.

In this embodiment, the co-forwarding server may receive a call request sent by the internet terminal based on the internet protocol. The call request sent by the internet terminal is used for requesting to perform a video session with the video networking terminal, and the call address carried in the call request can be understood as a call address adopted for calling the video networking terminal.

Step S602: and determining the address format of the call address, and converting the call request into a target call request matched with the video networking terminal according to a protocol conversion mode corresponding to the address format.

In this embodiment, different address formats of the call address may represent different call modes of the internet terminal for calling the video networking terminal, and further the co-forwarding server may perform protocol conversion on the call request based on different protocol conversion modes corresponding to the different call modes, so as to successfully send the converted target call request to the video networking terminal. For example, in the internet, the calling mode may include: a call mode of a Session Initiation Protocol (SIP) protocol and a call mode of an H323 protocol. The SIP protocol is used to establish and disconnect media sessions, and the h.323 protocol is used to specify which protocol is used to provide media services.

In particular, the co-forwarding server may parse the call address from the call request, thereby determining the address format of the call address. When the internet terminal needs to perform video session with the internet-of-view terminal in the internet-of-view, a call address can be input in a call address bar provided by the internet terminal, and specifically, the call address can include the internet-of-view number of the internet-of-view terminal and the IP address of the co-forwarding server in the internet.

In one implementation, the address format of the call address may refer to a location order between the internet of view number and the IP address of the co-ordination server, so that the corresponding protocol conversion mode is determined according to the location order between the internet of view number and the IP address of the co-ordination server.

Accordingly, the process of converting the call request into the target call request is as follows in step S6021 and step S6022:

Step S6021: when the prefix address in the call address is the video network number of the video network terminal, determining that the protocol conversion mode corresponding to the address format is an SIP protocol conversion mode, and converting the call request into a target call request which accords with the video network protocol and is matched with the SIP protocol according to the SIP protocol conversion mode.

In this embodiment, when the prefix address is the internet-of-view number of the internet-of-view terminal, that is, the internet-of-view number is located before the IP address of the co-ordination server, for example, the call address is: in this case, the co-transfer server can determine that the call mode of the internet terminal is the call mode of the SIP protocol, and can convert the call request into a target call request which accords with the internet of view protocol and matches with the SIP protocol according to the SIP protocol conversion mode. In the SIP protocol conversion mode, the co-conversion server may send the call request to the SIP protocol conversion module, so as to perform protocol conversion on the call request through the SIP protocol conversion module.

Specifically, the SIP protocol conversion module may convert the call request into a target call request for a SIP protocol call mode in the internet of view, where the target call request may be encapsulated by using an internet of view protocol. For example, the call request may be converted into 8E01 signaling in the internet of view, so that the internet of view terminal may parse the 8E01 signaling to successfully respond to the call request of the internet terminal.

Step S6022: when the prefix address in the call address is the IP address of the co-rotating server in the Internet, determining that a protocol conversion mode corresponding to the address format is an H323 protocol conversion mode, and converting the call request into a target call request which accords with a video networking protocol and is matched with the H323 protocol according to the H323 protocol conversion mode.

In this embodiment, when the prefix address is the IP address of the co-ordination server, that is, the internet-of-view number is located after the IP address of the co-ordination server, for example, the call address is: when the IP address +# # +91 of the co-forwarding server is the number of the internet-of-view terminal, in this case, the co-forwarding server may determine that the call mode of the internet terminal is the call mode of the H323 protocol, and may convert the call request into a target call request that conforms to the internet-of-view protocol and matches the H323 protocol according to the H323 protocol conversion mode. In the H323 protocol conversion mode, the coordination server may send the call request to the H323 protocol conversion module, so as to perform protocol conversion on the call request through the H323 protocol conversion module.

Specifically, the target call request in this case is a request for an H323 protocol call style within the video network, and for example, the call request may be converted into 8E00 signaling within the video network. Thus, the video networking terminal can analyze the 8E00 signaling to successfully respond to the H323 calling type calling request of the internet terminal.

It should be noted that, the 8E00 signaling in this example may be a protocol corresponding to a video call in the internet of view, that is, in a specific implementation, a call request in the SIP protocol manner or a call request in the H323 protocol manner adopted by the internet terminal may be converted into the signaling of 8E01 in the internet of view. Thus, no matter what way the internet terminal takes, the coordination server can be converted into a target call request which can be resolved by the video networking terminal.

Step S603: and sending the target call request to the video networking terminal.

In this embodiment, the target call request may be a request encapsulated by using a video networking protocol, and the target call request may be sent to the video networking terminal based on the video networking protocol.

Step S604: and when receiving a call reply signaling returned by the video networking terminal aiming at the target call request, establishing a video session link between the Internet terminal and the video networking terminal.

The video session link is used for transmitting audio and video data between the internet terminal and the video networking terminal.

In this embodiment, a call reply signaling returned by the internet-of-view terminal may be received, where in this case, it indicates that the internet-of-view terminal successfully responds to a call request of the internet terminal, and then a video session link between the internet terminal and the internet-of-view terminal may be established. So that the internet terminal and the video networking terminal can conduct video call through the video session link.

According to the embodiment of the invention, the protocol conversion mode corresponding to the address format of the call address can be determined by the co-conversion server, so that the call request is converted into the target call request matched with the video networking terminal, the requirement that the Internet terminal can call the video networking terminal in different calling modes is further met, and the service application range of the video networking can be widened and the user experience is optimized by adopting the embodiment of the invention.

In combination with the above embodiment, in an implementation manner, before the coordination server sends the target call request to the video networking terminal, the method may further include the following steps;

Step S6020: and responding to the call request, and determining a target virtual terminal from a plurality of preset virtual terminals.

In this embodiment, the co-rotation server may preset a plurality of virtual terminals, and each virtual terminal may be used to forward audio and video data in the internet and the video network. The target virtual terminal may be a terminal that does not forward audio and video data currently in the plurality of virtual terminals, that is, a virtual terminal in an idle state in the plurality of virtual terminals.

In practice, the target virtual terminal may be used to perform forwarding of audio and video data in a video conference conducted by the internet terminal and the video networking terminal. Specifically, the audio and video data sent by the internet terminal can be received and sent to the video networking terminal, and the audio and video data sent by the video networking terminal can be received and sent to the internet terminal.

Accordingly, when a video session link between the internet terminal and the video networking terminal is established, the method may include the steps of:

Step S6041: and when receiving a confirmation signaling returned by the video network terminal aiming at the target call reply signaling, establishing data communication links between the target virtual terminal and the Internet terminal and the video network terminal respectively so as to complete the establishment of the video session link.

In this embodiment, when receiving the acknowledgement signaling returned by the internet-of-view terminal for the target call reply signaling, it indicates that the internet-of-view terminal successfully responds to the call request of the internet terminal, and in practice, the co-ordination server may also send the reply acknowledgement signaling to the internet terminal for the acknowledgement signaling, so that the internet terminal knows that the internet-of-view terminal has received the call of itself, and at this time, the co-ordination server may implement forwarding of audio and video data between the internet terminal and the internet-of-view terminal through the target virtual terminal.

In particular, the corotation server may establish a first data communication link between the target virtual terminal and the internet terminal and a second data communication link between the target virtual terminal and the video networking terminal. In this way, the target virtual terminal can play a role of communication bridging between the internet terminal and the video networking terminal, thereby completing the establishment of the video session link between the internet terminal and the video networking terminal.

Accordingly, after the video session link is established by using the target virtual terminal, the video session can be performed based on the video session link.

In one embodiment, in order to ensure that audio and video data between the internet terminal and the video networking terminal can be normally transmitted, that is, the audio and video data sent by the internet terminal can be normally decoded and played by the video networking terminal, a codec may be configured in the target virtual terminal.

Referring to fig. 5, the co-rotating server may also be connected to a view networking server, and the view networking server may be used to receive call reply signaling sent by the view networking terminal.

As shown in fig. 5, the internet of view server may be connected between the internet of view terminal and the coordination server, so that the call reply signaling sent by the internet of view terminal may be sent to the coordination server via the internet of view server. In this case, the target call request sent by the co-ordination server may be sent to the internet of view terminal via the internet of view server.

Accordingly, in the case of having a view networking server, the corotation server may also perform the following steps:

Step S6042: and receiving an audio and video control request sent by the video networking server aiming at the call reply signaling.

Step S6043: and starting the coder-decoder based on the audio/video control request, wherein the coder-decoder is used for converting the first audio/video data sent by the Internet terminal into the second audio/video data adapted to the video networking terminal, and converting the third audio/video data sent by the video networking terminal into the fourth audio/video data adapted to the Internet terminal.

Because the establishment of the video session link between the internet terminal and the video network terminal is completed after the call reply signaling of the video network terminal is received by the co-rotating server, at this time, the video network server can also send an audio and video control request to the co-rotating server when receiving the call reply signaling so as to start a codec configured for the target virtual terminal, and the codec can be a soft codec.

Specifically, when receiving a call reply signaling returned by the video network terminal, the video network server can send the call reply signaling and an audio/video control request to the co-rotation server, and the co-rotation server can start a codec configured by the target virtual terminal while establishing a video session link.

In a specific implementation, the video networking server may send 8704 audio/video control instructions, and send the 8704 audio/video control instructions to the coordination server and the video networking terminal, respectively. Therefore, the video networking terminal can automatically send the video networking audio and video data acquired by the video networking terminal to the cooperative server according to the instruction, and the cooperative server converts the audio and video data into Internet audio and video data by utilizing encoding and decoding, so that the Internet audio and video data is sent to the Internet terminal.

Under the condition, when the video networking terminal returns a call reply signaling to the cooperative server, the video networking terminal can automatically send the self-collected Internet audio and video data to the cooperative server, and the codec of the cooperative server re-encodes and decodes the Internet audio and video data and then sends the re-encoded Internet audio and video data to the Internet terminal. When receiving a call reply signaling returned by the video networking terminal and forwarded by the coordination server, the internet terminal can send the internet audio and video data acquired by the internet terminal to the coordination server, and a codec of the coordination server re-encodes and decodes the internet audio and video data and then sends the re-encoded internet audio and video data to the video networking terminal.

Illustratively, the video networking terminal forwards the 2001-protocol video networking audio stream to the co-ordination server, and the codec of the co-ordination server decapsulates the 2001-protocol video networking audio stream into g711 audio stream and transmits the g711 audio stream to the internet terminal. After receiving the call reply signaling of the video networking terminal, the internet terminal can send the audio stream of g711 acquired by the internet terminal to the cooperative server, and the codec of the cooperative server de-encapsulates the audio stream of g711 into a video networking audio stream of 2001 protocol and sends the video networking audio stream to the video networking terminal.

In one embodiment, the co-rotating server may record a protocol conversion mode adopted by the internet terminal when the video session is performed, so that when the video session needs to be completed by the internet terminal, the co-rotating server may receive, through the target virtual terminal, a session completion request sent by the internet terminal, and still perform protocol conversion on the session completion request according to the recorded protocol conversion mode according to the process described in step S602, and then send the session completion request to the internet-of-view terminal, so as to disconnect a video session link between the internet terminal and the internet-of-view terminal, that is, disconnect a first data communication link and a second data communication link between the target virtual terminal and the internet-of-view terminal, respectively, so as to disconnect the video session link.

The video session establishment method of the present application will be described with reference to the communication environment diagram shown in fig. 5 from the internet terminal side, and referring to fig. 7, a flowchart showing steps of the video session establishment method in an embodiment of the present application is shown, and the internet terminal may specifically execute the following steps:

Step S701: and acquiring the call address input by the user in the preset address bar.

The preset address bar may be configured on the internet terminal, and in particular, the preset address bar may be an address bar configured on a video session client on the internet terminal. The video session client may be used to provide video session services for users across the internet of view and the internet, for example, the video session client may be a pamil client.

In specific implementation, a user may log in to a video session client, and further input an address corresponding to a video networking terminal to be called in a preset address bar configured by the client. The call address may include a video network number of the video network terminal in the video network, and an IP address of the co-rotating server in the internet.

The video network number is a number allocated when the video network terminal registers to the video network, and the video network number can be used for uniquely identifying the video network terminal.

Step S702: determining an address format of the call address and a call protocol corresponding to the address format.

In this embodiment, the internet terminal may determine the address format of the input call address according to the prefix address in the call address, and further may determine the corresponding call protocol according to the address format of the input call address. The call protocol may be understood as a session protocol in which an internet terminal is to conduct a video session, and may specifically include a SIP protocol and an H323 protocol.

In one embodiment, if the prefix address is the internet of view number of the internet of view terminal, that is, the internet of view number is located before the IP address of the co-ordination server, the internet terminal may determine that the call protocol corresponding to the call address is a call protocol of SIP protocol.

If the prefix address is an IP address of the co-forwarding server in the internet, that is, the internet-of-view number is located after the IP address of the co-forwarding server, in this case, the internet terminal may be adapted to a call mode in which the call protocol corresponding to the call address is an H323 protocol.

Step S703: generating a call request including the call address, and encapsulating the call request with the call protocol.

In this embodiment, the internet terminal generates a call request based on the call address, and encapsulates the call request using a corresponding call protocol. Specifically, if the call protocol is the SIP protocol, the SIP protocol is used to encapsulate the call request, and if the call protocol is the H323 protocol, the H323 protocol is used to encapsulate the call request.

By adopting the embodiment, the internet terminal can support different calling habits of the user, for example, the user is used to input the video networking number and then input the IP address of the co-forwarding server, and the internet terminal can call the video networking terminal by adopting the SIP protocol. If the user is used to input the IP address of the co-forwarding server before inputting the video networking number, the Internet terminal can call the video networking terminal by adopting the H323 protocol. Therefore, the internet terminal can meet the calling habit of the user, so that the user experience is optimized.

Step S704: and sending the call request packaged by the call protocol to the coordination server.

The co-rotating server is used for converting the call request into a target call request matched with the video networking terminal according to the address format of the call address, and sending the target call request to the video networking terminal so as to establish a video session link between the Internet terminal and the video networking terminal.

In this embodiment, the internet terminal may send the call request to the coordination server by using the internet communication protocol, where the procedure of establishing the video session link by the coordination server in response to the call request may be described in the above steps S602 to S604, which is not described herein again.

Step S705: and based on the video session link, performing audio and video data interaction with the video networking terminal.

After the video session link is established by the co-rotating server, the Internet terminal can transmit audio and video data with the video networking terminal. The specific process can be described in detail in the above step S6042 and step S6043, and will not be described herein.

The video session establishment method of the present invention will be described in detail by way of a specific example. This example takes the internet as the internet and the visual networking as an example.

(3) The co-rotating server sends the 8e01 signaling to the video networking server, and the video networking server converts the 8e01 signaling into 8e02 signaling and sends the 8e02 signaling to the aurora terminal.

(4) After receiving 8e02, the aurora terminal replies 8e01 response to the video networking server, and the video networking server converts the 8e01 reply into 8e02 reply and sends the 8e02 reply to the corotation server.

(5) After receiving the reply, the cooperative forwarding server forwards the 200OK reply of the signaling converted into the sip protocol to the Hua serving terminal, and after receiving the 200OK, the Hua serving te30 replies an ACK signaling indicating that the auroral terminal is known to answer normally. At this time, the corotation server establishes a communication connection with the Hua te30 and the aurora terminal using one target virtual terminal.

(6) In the process of starting and ending the call, the video networking server can send 8704 protocol signaling to the corotation server and the aurora terminal to enable the corotation server and the aurora terminal to open and close audio and video codecs, so that the audio and video can be normally transmitted.

(7) At this time, the te30 starts to send h264 video stream and G711 audio stream to the corotation server, and the corotation server packages the two paths of video streams, namely 2002 and 2001 media streams, respectively, and sends them to the aurora terminal, and at the same time, unpacks the 2001 and 2002 media streams sent by the aurora terminal into G711 and h264 streams and sends them to the te30.

(8) When the conference needs to be ended, the BYE signaling is sent to the target virtual terminal configured by the cooperative server for the video session link by the aid of the terminal, and the target virtual terminal converts the signaling into a hanging-up signaling 8e01 of the video networking protocol.

(9) The target virtual terminal sends the hang-up signaling 8e01 signaling to the video networking server, and the video networking server converts 8e01 into 8e02 and sends the 8e02 to the aurora terminal.

(10) After receiving 8e02, the aurora terminal replies 8e01 to the video networking server and ends the conference, and the video networking server converts the 8e01 reply into 8e02 reply and sends the 8e02 reply to the target virtual terminal of the corotation server.

(11) After receiving the reply, the target virtual terminal transmits a 200OK reply of the sip protocol to the Hua Cheng te30, and then disconnects the video session between the Hua Cheng te30 and the aurora terminal, thereby ending the video session.
