To better understand the embodiments of the present invention, the following description refers to the internet of view:

some of the technologies applied in the video networking are as follows:

network Technology (Network Technology)

Network technology innovation in video networking has improved 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 Packet Switching is adopted by the technology of the video networking to meet the Streaming requirement. The video networking technology has the advantages of flexibility, simplicity and low price of packet switching, and simultaneously has the quality and safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.

The video network adopts two advantages of asynchronism and packet exchange of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, and has end-to-end seamless connection of the whole network, direct connection with a user terminal and direct bearing of an IP data packet. The user data does not require any format conversion across the entire network. The video network is a higher-level form of the Ethernet, is a real-time exchange platform, can realize the large-scale high-definition video real-time transmission of the whole network which can not be realized by the current Internet, and pushes a plurality of 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 traditional server, the streaming media transmission of the video networking and unified video platform is established on the basis of connection orientation, the data processing capacity of the video networking and unified video platform is independent of flow and 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 over one hundred times compared with that of the traditional server.

The super-high speed memory technology of the unified video platform adopts the most advanced real-time operating system in order to adapt to the media content with super-large capacity and super-large flow, the program information in the server instruction is mapped to the specific hard disk space, the media content is not passed through the server any more, and is instantly and directly sent to the user terminal, and the user waiting time is less than 0.2 second. The optimized sector distribution greatly reduces the mechanical motion of the magnetic head track seeking of the hard disk, the resource consumption only accounts for 20% of that of the IP internet of the same grade, but concurrent flow which is 3 times larger 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 network completely eliminates the network security problem troubling the internet structurally by the modes of independent service permission control each time, complete isolation of equipment and user data and the like, generally does not need antivirus programs and firewalls, avoids the attack of hackers and viruses, and provides a structural carefree security network for users.

Service Innovation Technology (Service Innovation Technology)

The unified video platform integrates services and transmission, and is not only automatically connected once, but also connected with a single user, a private network user or the sum of one network. The user terminal, the set-top box or the PC are directly connected to the unified video platform to obtain various multimedia video services in various forms. 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 two parts, 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 may be directly connected to the access switch or may be directly connected to 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 and can also be 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.

The access network part can form a unified video platform (the part in the dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.

Video networking device classification

1.1 devices in the video network of the embodiment of the present invention can be mainly classified into 3 types: server, exchanger (including Ethernet protocol gateway), terminal (including various set-top box, coding board, memory, etc.). The video network as a whole can be divided into a metropolitan area network (or national network, global network, etc.) and an access network.

1.2 wherein the devices of the access network part can be mainly classified into 3 types: node server, access exchanger (including Ethernet protocol conversion gateway), terminal (including various set-top boxes, coding board, memory, etc.).

the network interface module 201, the CPU module 203, and the disk array module 204 all enter the switching engine module 202; the switching engine module 202 performs an operation of looking up the address table 205 on the incoming packet, thereby obtaining the direction information of the packet; and stores the packet in a queue of the corresponding packet buffer 206 based on the packet's steering information; if the queue of the packet buffer 206 is nearly full, it is discarded; the switching engine module 202 polls all packet buffer queues for forwarding if the following conditions are met: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero. The disk array module 204 mainly implements control over the hard disk, including initialization, read-write, and other operations on the hard disk; the CPU module 203 is mainly responsible for protocol processing with an access switch and a terminal (not shown in the figure), configuring an address table 205 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 204.

The access switch:

wherein, the packet (uplink data) coming from the downlink network interface module 301 enters the packet detection module 305; the packet detection module 305 detects whether the Destination Address (DA), the Source Address (SA), the packet type, and the packet length of the packet meet the requirements, and if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 303, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 302 enters the switching engine module 303; the incoming data packet of the CPU module 304 enters the switching engine module 303; the switching engine module 303 performs an operation of looking up the address table 306 on the incoming packet, thereby obtaining the direction information of the packet; if a packet entering the switching engine module 303 is destined for an upstream network interface from a downstream network interface, the packet is stored in a queue of the corresponding packet buffer 307 in association with a stream identifier (stream-id); if the queue of the packet buffer 307 is nearly full, it is discarded; if the packet entering the switching engine module 303 is not from the downlink network interface to the uplink network interface, the data packet is stored in the queue of the corresponding packet buffer 307 according to the guiding information of the packet; if the queue of the packet buffer 307 is close to full, it is discarded.

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 divided into an in label and an out label, and assuming that the label (in label) of the data packet entering the device a is 0x0000, the label (out label) of the data 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, which is located between the reserved bytes and the payload of the packet.

In order to facilitate a more accurate understanding of the present invention for those skilled in the art, the following description will be given by way of a specific example of the technical problem of the present invention:

the existing operating rooms A, B and C are operated at the same time, a plurality of video network terminals are arranged in each operating room, and each video network terminal acquires video data of an operating site from different angles in the operating room. At this time, the user needs to monitor the field situation of the three operating rooms.

In the prior art, a user can only dynamically join a conference A through one video network terminal M, and then the user communicates with each video network terminal in the conference A, so that video pictures of different video network terminals are viewed, and multi-angle monitoring and broadcasting of an operation A are realized. However, if the user wants to view any one of the pictures of the operating room B or the operating room C, the video networking terminal M can only be dynamically removed from the conference a, and then the video networking terminal M is dynamically added to the conference B or the conference C. Or the user wants to view the pictures of three operating rooms at the same time, the user needs to join A, B, C three conferences through three video networking terminals respectively.

That is to say, the video network terminal M can only join one conference at a time to monitor and broadcast the video images of one operating room, and the user cannot monitor and broadcast one or more video images of the operating room a and one or more video images of the operating room B or one or more video images of the operating room C at the same time, so that the flexibility of the monitoring and broadcasting process is low, and the manpower, material resources and financial resources are consumed.

the conference management server 501 is configured to control the start and end of the video network terminal conference, dynamically add and remove video network terminals to the conference, record detailed information of the conference, and perform backup and display based on the video network and each video network terminal in the video network in communication connection. In the embodiment of the present invention, the conference management server 501 is mainly used for controlling the start and end of a conference and dynamically adding virtual terminals.

It should be noted that the video network terminal in the embodiments of the present invention may be an intelligent device equipped with a camera, and the intelligent device may include, but is not limited to, a set-top box, a mobile phone, and an all-in-one machine. The terminal of the video network may be configured with an android system, and includes the network interface module, the service processing module, and the CPU module described in the above content 1.2, where the network interface module may be configured with a video network card, and the video network card is used to access the video network through a core server of the video network, and receive or send data based on a video network protocol through the video network, such as sending a request to join a conference to the conference management server 501, or receiving a notification sent by the conference management server 501, and the like. The core server of the video network can provide servers for all terminals in the video network to provide services such as registration, data forwarding, signaling control and the like, and data generated by each terminal can be sent to the core server of the video network firstly and then forwarded to a target terminal by the core server of the video network.

The multi-conference video monitoring Client 503 belongs to one of video networking terminals, and may be a Client program running based on a Client/Server architecture C/S (Client/Server) or a Browser/Server architecture B/S (Browser/Server). In the embodiment of the present invention, the multi-conference video-monitoring client 503 is configured with an IP and a port of the "video-monitoring service" of the multi-conference video-monitoring server 502, and is used for communicating with the video-monitoring service; the multi-conference video monitoring and broadcasting client 503 mainly displays conference information in a list form, issues monitoring and broadcasting control commands to the multi-conference video monitoring and broadcasting server 502, pushes video data of the client to the server, and receives and broadcasts the monitoring and broadcasting conference video data.

The multi-conference video hosting server 502 is provided with a "conference management service" interface that establishes link communication with the conference management server 501 through the internet (IP and port). In practical applications, the multi-conference video monitoring server 502 of the embodiment of the present invention may be connected to a plurality of conference management servers 501 to switch conference objects in different local area networks.

The virtual terminal is also called a virtual video network terminal, is another expression form of the video network terminal, is a software system encapsulated by codes, and after a program runs, the software system corresponds to a special and unique digital code (virtual terminal number) (for example: 1001/1002/1003 …), and can carry out video network meeting starting, meeting stopping, dynamic adding to a meeting, dynamic removing from the meeting and other service capabilities possessed by the video network terminal.

Based on the system shown in fig. 5, referring to fig. 6, a flowchart of a first step of a video data pushing method according to an embodiment of the present invention is shown, and is applied to the multi-conference video monitoring server 502, and specifically may include the following steps:

step S601, receiving a conference start notification sent by the conference management server 501; the conference opening notification comprises conference information, and the conference information comprises a conference ID of a currently opened conference object;

the conference management server 501 is configured to pull a plurality of video networking terminals that need to participate in the entity conference into the conference according to the conference requirement, so as to complete the establishment of a video conference. The process of the conference management server 501 for establishing the video conference is the prior art, and is not a core invention point of the present invention, and is not described herein again.

In the embodiment of the invention, the conference object refers to a video conference in a real environment. In a certain lan environment, a plurality of video conferences are started simultaneously, and the conference management server 501 creates a corresponding conference object in its own conference start service module according to the actually created video conference.

After the conference management server 501 starts a corresponding conference, the conference management server calls a notification conference start interface of the multi-conference video monitoring server 502, and sends conference information to the multi-conference video monitoring server 502.

Since a video conference is participated by a plurality of video networking terminals, each conference object comprises a plurality of video networking terminals; and each video network terminal corresponds to one video stream.

In an optional embodiment of the present invention, it is shown that the conference information further includes a conference name corresponding to the conference ID, a conference start time, and a plurality of pieces of video networking terminal information. The conference ID represents a conference object and is a unique identifier of the conference object. The conference name is a specific name of the conference object, and is used for being presented at the multi-conference video monitoring client 503, so that a user of the multi-conference video monitoring client 503 can quickly know the conference, and the conference name can be in various forms, for example, the conference name can be a number, such as 001; the name of the meeting room of the entity meeting, such as meeting room 1, operating room 1, etc.; of course, the meeting name may also be created according to a specific meeting topic, such as a second internal meeting in product development. The terminal information of the video networking may include information such as an identifier, a name, an online status, and a placement position in the video conference of the video networking terminal, so that the user of the multi-conference video monitoring client 503 can call a video stream collected by the corresponding video networking terminal.

The multi-conference video monitoring and broadcasting server 502 comprises a database, and after obtaining the conference information, the multi-conference video monitoring and broadcasting server 502 executes the following steps:

storing the meeting information in the database in the form of a meeting information list. Since the multi-conference video surveillance server 502 can be communicatively connected to a plurality of conference management servers 501, different conference information lists may exist for conferences started by different conference management servers 501, that is, the database stores a plurality of conference information lists.

In addition, in order to facilitate the user to know the currently opened conference situation in time, in a preferred embodiment of the present invention, the following method is provided, which specifically includes the following steps:

step one, receiving a conference information obtaining instruction sent by the multi-conference video monitoring client 503; the conference information acquisition instruction is generated by the multi-conference video monitoring client 503 when starting;

in the embodiment of the present invention, the conference information obtaining instruction is automatically generated by the multi-conference video monitoring client 503 when starting, so that the user of the client can obtain the conference opening conditions in the multiple local area networks at the first time.

And step two, sending the conference information to the multi-conference video monitoring client 503 in a conference information list form according to the conference information acquisition instruction.

When receiving the conference information acquisition instruction, the multi-conference video monitoring server 502 extracts the conference information list from its own database, and then pushes the conference information list to the multi-conference video monitoring client 503. The embodiment of the invention stores the conference information in the form of the conference information list, so that the conference information is clearer and can be conveniently viewed by a user using the client when being pushed to the client.

Step S602, selecting a target virtual terminal in an idle state from the plurality of virtual terminals according to each conference ID in the conference information;

step S603, sending a dynamic adding command for adding the target virtual terminal to a target conference object corresponding to the conference ID to the conference management server;

the selection of the target virtual terminal in the idle state from the plurality of virtual terminals by the multi-conference video surveillance server 502 may be performed in the following manner:

first, the multi-conference video hosting server 502 selects an idle virtual terminal according to an instruction sent by the multi-conference video hosting client 503.

Specifically, after receiving the conference information, the multi-conference video monitoring and broadcasting client 503 sends a virtual terminal search instruction carrying a conference ID to the multi-conference video monitoring and broadcasting server 502; the multi-conference video monitoring server 502 searches for a target virtual terminal in an idle state (the idle state refers to that the virtual terminal does not carry a flag in a service) from a plurality of virtual terminals configured by itself according to the instruction, and then generates a dynamic addition command for the target virtual terminal. The dynamic addition command includes the target virtual terminal and the conference ID, and instructs the conference management server 501 to add the target virtual terminal to the conference object corresponding to the conference ID. By the method, the virtual terminal can be occupied according to the requirements of the user, the problem that the virtual terminal is occupied and not used in time to cause resource waste of the virtual terminal is avoided, and the utilization rate of the virtual terminal can be improved.

Secondly, after receiving the conference information sent by the conference management server 501, the multi-conference video monitoring server 502 selects an idle virtual terminal by using the conference information as a trigger signal.

Specifically, the multi-conference video surveillance server 502 reads conference IDs from the conference information, determines the number of the conference IDs, and then selects a target virtual terminal in an idle state from the plurality of virtual terminals according to the number, such as the number of the selected target virtual terminal and the conference IDs in the conference information. Next, the multi-conference video surveillance server 502 randomly establishes a one-to-one correspondence between the conference ID and the plurality of target virtual terminals, and then generates a corresponding dynamic addition command. In this way, the target virtual terminal can be selected most quickly to complete the subsequent virtual terminal adding steps, and meanwhile, the multi-conference video monitoring and broadcasting server 502 is not influenced to synchronously send the conference information to the multi-conference video monitoring and broadcasting client 503, which is beneficial to saving data flow.

According to the two modes, the number of the conference IDs and the number of the virtual terminals contained in the generated dynamic adding command are the same, and the dynamic adding command is a conference ID and a target virtual terminal.

If the conference management server 501 starts three conferences, namely a conference object a, a conference object B and a conference object C, conference IDs of the three conference objects are A, B, C respectively; the virtual terminals searched by the multi-conference video monitoring server 502 are 1001, 1002 and 1003 respectively; the generated dynamic addition commands are dynamic addition command 1, dynamic addition command 2 and dynamic addition command 3, respectively. Then, the generated dynamic addition command 1 contains a and 1001, the dynamic addition command 2 contains B and 1002, and the dynamic addition command 3 contains C and 1003.

In the embodiment of the present invention, the multi-conference video surveillance server 502 invokes a "conference management service" interface, sends a dynamic addition command to the conference management server 501, and then the conference management server 501 adds a target virtual terminal to a target conference object corresponding to the conference ID.

If the conference IDs of the three conference objects are A, B, C respectively, the dynamic addition commands are 1,2, and 3 respectively; dynamic add command 1 contains a and 1001, dynamic add command 2 contains B and 1002, and dynamic add command 3 contains C and 1003. Then, the conference management server 501 adds the virtual terminal 1001 to the conference object corresponding to the conference ID a according to the dynamic addition command 1; similarly, according to the dynamic adding command 2, adding the virtual terminal 1002 to the conference object corresponding to the conference ID B; and adding the virtual terminal 1003 to the conference object corresponding to the conference ID C according to the dynamic addition command 1. The adding step performed by the conference management server 501 is the prior art, and is not a protection point of the present invention, and is not described herein again.

Step S604, after the target virtual terminal is added into the corresponding conference, receiving the video data of the target conference object through the target virtual terminal, and storing the video data;

after the conference management server 501 completes adding the target virtual terminal, the target virtual terminal in the multi-conference video monitoring server 502 is marked as a service, which indicates that the target virtual terminal is not in an idle state. Next, the multi-conference video surveillance server 502 may receive the video data of the target conference object through the target virtual terminal.

Since a plurality of video network terminals are included in a conference object, the multi-conference video surveillance server 502 can receive one or more video streams through a target virtual terminal to receive pictures collected by one video network terminal or a plurality of video network terminals. Each video stream is composed of a plurality of data packets, and during the transmission of the data packets, due to network delay or other problems, the data packets of each video network terminal may not reach the multi-conference video monitoring server 502 in sequence, and there may also be a streaming phenomenon. In an optional embodiment of the present invention, the video data comprises a plurality of data packets, and the data packets comprise video networking terminal information;

the step S604 may include the steps of:

sequentially receiving data packets of the target conference object through the target virtual terminal;

By this embodiment, the multi-conference video surveillance server 502 can complete the arrangement of each video stream, and save the data packets collected by the video network terminals to avoid streaming video pictures.

Step S605, receiving a video monitoring control command sent by the multi-conference video monitoring client 503 for the conference information; the video monitoring and playing control command is generated by the multi-conference video monitoring and playing client 503 when receiving a triggering operation of switching video data in an interface for displaying the conference information, and includes a target conference ID;

step S606, according to the video monitoring control command, pushing the target video data corresponding to the target conference ID to the multi-conference video monitoring client 503.

In the embodiment of the present invention, after the multi-conference video monitoring client 503 displays the conference information, the user may select a video to be monitored in the interface to perform a video data switching operation. The video frames presented by the conference information and the video data may be located in the same display interface of the multi-conference video monitoring client 503, so that the monitoring and broadcasting switching can be performed at any time by the user.

Specifically, the triggering operation for switching the video data may include at least the following actions: the selection operation of the target conference information list selects one target conference ID among the plurality of conference IDs of the target conference information list. For the trigger operation, the multi-conference video monitor client 503 generates a video monitor control command and sends the video monitor control command to the multi-conference video monitor server 502. After receiving the target video data, the multi-conference video monitoring server 502 pushes the target video data corresponding to the target conference ID to the multi-conference video monitoring client 503. At this time, the multi-conference video monitoring client 503 receives video data (multi-channel video streams) collected by all video networking terminals in the conference object corresponding to the target conference ID, and the multi-channel video streams are displayed as a plurality of video frames in a split screen manner in the multi-conference video monitoring client 503. In this scheme, the number of the conference IDs requested by the video monitoring control command is one, for example, the video monitoring control command requests video data with a conference ID a, and there are two video networking terminals, respectively terminals a1 and a2, in the conference object with the conference ID a, so that two video pictures, respectively video pictures a1 and a2, are displayed on the multi-conference video monitoring client 503. By the embodiment of the invention, a plurality of video networking terminals of one video conference can be monitored and broadcast simultaneously, so that a user can know the conference condition of each angle or position of the conference more comprehensively.

Of course, the number of the target conference IDs selected from the conference IDs in the target conference information list may also be multiple, and in a preferred embodiment of the present invention, it is shown that, under the trigger operation, the number of the target conference IDs in the generated video monitoring control command is multiple; step S606 may further include the steps of:

and pushing a plurality of target video data respectively corresponding to the target conference ID to the multi-conference video monitoring client 503 simultaneously according to the video monitoring control command. Through the above steps, the multi-conference video monitor client 503 can simultaneously display the video frames of a plurality of conference objects. If the video monitoring control command requests video data with a conference ID of A and a conference ID of B, two video networking terminals, namely a terminal a1 and a terminal a2, are arranged in a conference object with the conference ID of A; there are 1 video network terminals in the conference object with conference ID B, which is terminal B1. Three video frames, a1, a2, and b1, are displayed on the multi-conference video hosting client 503. By the embodiment of the invention, the simultaneous monitoring and broadcasting of a plurality of video conferences can be realized.

Further, the triggering operation for switching the video data may further include a selecting operation for selecting one or more pieces of video network terminal information. In a preferred embodiment of the present invention, it is shown that, under the trigger operation, the generated video surveillance control command further includes target video network terminal information corresponding to the target conference ID; step S606 may further include the steps of:

and pushing a data packet corresponding to the target video networking terminal information corresponding to the target conference ID to the multi-conference video monitoring client 503 according to the video monitoring control command. Through the above steps, the multi-conference video monitor client 503 may only display the video frames of the designated video networking terminals in one conference object, for example, there are three video networking terminals, namely terminals a1, a2 and a3, in the conference object with the conference ID a, the video monitor control command requests that the conference ID a and the video networking terminal information include the video data of a3, and then one video frame, namely a3 video frame, is displayed on the multi-conference video monitor client 503. By the embodiment of the invention, one-to-one monitoring and broadcasting can be carried out on one video network terminal of one video conference, for example, one-to-one video session, guidance and the like are carried out on the video network terminal, so that the conference monitoring and broadcasting are more targeted.

In conclusion, the embodiment of the invention can realize the simultaneous monitoring and viewing of one or more video pictures of the conference A, one or more video pictures of the conference B or one or more video pictures of the conference C, has flexible monitoring and viewing process, is beneficial to saving manpower, material resources and financial resources, and makes great progress compared with the existing monitoring and viewing mode. It should be noted that the physical conference corresponding to the conference object in the embodiment of the present invention may be an operating room, and the embodiment of the present invention is particularly suitable for monitoring and broadcasting multiple operating rooms, has low delay in the switching process, and can facilitate experts or professors to analyze the operating conditions of each operating room in time and make corresponding decisions and guidance.
