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.

Referring to fig. 5, fig. 5 is a structural diagram of an electronic whiteboard sharing system according to an embodiment of the present invention. As shown in fig. 5, the electronic whiteboard sharing system includes a streaming server 1, a streaming server 2, a sharing server, a video network terminal 1, and a video network terminal 2. The streaming media server 1 and the streaming media server 2 may be servers providing media streams, the streaming media server 1 may provide media streams for the video network terminal 1, and the streaming media server 2 may provide media streams for the video network terminal 2. The video network terminal 1 and the video network terminal 2 may be devices connected to the video network, such as a mobile phone, a tablet computer, and a computer, and communicating with the streaming media server 1, the streaming media server 2, and the sharing server through the video network. The sharing server enables the video network terminal 1 and the video network terminal 2 to share the electronic whiteboard.

In the embodiment of the invention, a user can configure corresponding related information for each video network terminal accessed to the streaming media server through the streaming media server, and the stored related information is distributed to the corresponding video network terminal, and the video network terminal can log in the streaming media server by using the related information to acquire the media stream from the streaming media server. For example, referring to fig. 5, a user may configure a first account and a password to the video network terminal 1 through the streaming server 1, and the video network terminal 1 may log in to the streaming server 1 through the first account and the password to obtain a media stream from the streaming server 1. Similarly, the user may configure a second account and a password for the video network terminal 2 through the streaming media server 2, and the video network terminal 2 may log in the streaming media server 2 through the second account and the password to obtain the media stream from the streaming media server 2. Meanwhile, the terminal 1 of the video network may log in the shared server by using the first account and the password as login information for logging in the shared server, and the terminal 2 of the video network may log in the shared server by using the second account and the password as login information for logging in the shared server. The video network terminal 1 and the video network terminal 2 which log in the sharing server can realize electronic whiteboard sharing through the sharing server.

It should be noted that, for ease of understanding, the electronic whiteboard sharing system only includes the streaming server 1, the streaming server 2, the video network terminal 1, and the video network terminal 2. Those skilled in the art should know that, in actual use, the number of the streaming media servers in the electronic whiteboard sharing system may be multiple, and the number of the video networking terminals accessing to each streaming media server may be multiple, and in this embodiment, the number of the streaming media servers and the video networking terminals is not specifically limited.

Referring to fig. 6, fig. 6 is a flowchart illustrating a step of a first electronic whiteboard sharing method according to an embodiment of the present invention, where the method is executed in a sharing server, and specifically includes the following steps:

step 601, obtaining second information of the respective video network terminals of the at least two streaming media servers according to the stored first information of the respective at least two streaming media servers.

In this embodiment of the present invention, the first information may include a name and an address of the streaming server. The name can be name information which is set by a user and used for distinguishing different streaming media servers, and a corresponding name is set for each streaming media server, so that the user can conveniently identify and check each streaming media server to manage a plurality of streaming media servers. The address may be an IP address, and the sharing server may send a data request to each corresponding streaming server through the address information to obtain data from the streaming server. For example, referring to fig. 5, the first information of the streaming server 1 may include: name: streaming server 1, address: 10.1.24.32. The first information of the streaming server 2 may include: name: streaming server 2, address: 10.1.24.33.

The second information may be an account and a password configured by the user for each video network terminal accessing the streaming server through the streaming server, and the video network terminal may log in the corresponding streaming server through the second information. For example, referring to fig. 5, the second information may be a first account and a password configured by the user for the video network terminal 1 through the streaming media server 1, and a second account and a password configured by the user for the video network terminal 2 through the streaming media server 2.

The sharing server can acquire second information of all video network terminals which can access the streaming media server from each streaming media server according to the stored first information of each streaming media server. For example, referring to fig. 5, the sharing server may transmit a data request for acquiring the second information of the terminal 1 of the video network stored in the streaming server 1 to the streaming server 1 according to the address information included in the first information of the streaming server 1. After receiving the data request sent by the sharing server 1, the streaming server 1 sends second information of the video network terminal 1 (referring to fig. 5, the second information may include a first account and a password) to the sharing server in response to the data request, and the sharing server receives and stores the second information of the video network terminal 1 sent by the streaming server 1. Similarly, the sharing server may obtain and store second information (in conjunction with fig. 5, the second information may include a second account and a password) of the video network terminal 2 from the streaming server 2.

For the convenience of understanding, the second information of the video network terminal 1 and the video network terminal 2 only includes the first account and the password, and those skilled in the art should understand that other related information may be included in the second information.

Step 602, receiving an electronic whiteboard creating request sent by a first video network terminal, where the first video network terminal is a video network terminal of a first streaming media server of at least two streaming media servers and is a video network terminal that logs in to a shared server by using second information of the first video network terminal.

In the embodiment of the invention, each video network terminal can log in the corresponding streaming media server through the second information and can log in the sharing server through the second information. For example, in connection with the example in step 601, the sharing server obtains and stores the second information of the video network terminal 1 and the video network terminal 2 from the streaming server 1 and the streaming server 2, respectively. The sharing server can determine the identity of the terminal 1 of the video network through the stored second information of the terminal 1 of the video network, and the sharing server stores the second information of the terminal 1 of the video network, so that the terminal 1 of the video network is allowed to log in the sharing server. Similarly, the sharing server may determine the identity of the terminal 2 through the stored second information of the terminal 2, and allow the terminal 2 to log in the sharing server.

The first streaming media server is any streaming media server, and the first video network terminal is any video network terminal which can be accessed to the first streaming media server. For convenience of understanding, in this embodiment, the streaming media server 1 is taken as a first streaming media server, and the video network terminal 1 that can access the streaming media server 1 is taken as a first video network terminal for example. Referring to fig. 5, the terminal 1 of the video network may log in the streaming server 1 and the sharing server through the first account and the password, respectively. After the video network terminal 1 logs in the sharing server through the first account and the password, the sharing server may receive a request for creating an electronic whiteboard sent by the video network terminal 1.

Step 603, creating an electronic whiteboard on the sharing server according to the electronic whiteboard creating request.

In this embodiment, after receiving the electronic whiteboard creating request sent by the first video network terminal, the sharing server creates an electronic whiteboard according to the electronic whiteboard creating request. Meanwhile, the sharing server can set parameters such as the theme, the identification, the password, the number of sharing people and the like of the electronic whiteboard according to the information such as the theme, the identification, the password, the number of sharing people and the like included in the request for creating the electronic whiteboard sent by the first video networking terminal. The theme is the name of the electronic whiteboard, the identification is identification information for uniquely identifying the electronic whiteboard, the password is a verification password input when other video network terminals access the electronic whiteboard, and the number of shared people is the specific number of people accessing the shared electronic whiteboard.

For example, with reference to fig. 5 in combination with the examples in steps 601 to 602, after receiving the electronic whiteboard creating request sent by the video network terminal 1, the sharing server establishes an electronic whiteboard corresponding to the electronic whiteboard creating request according to the electronic whiteboard creating request sent by the video network terminal 1. The sharing server may name the electronic whiteboard according to the received theme information included in the request for creating an electronic whiteboard sent by the video network terminal 1, and create the electronic whiteboard with the name of the electronic whiteboard being the theme information, where the theme information may be any theme information input by the user of the video network terminal 1, for example: for example, week meeting, technical communication meeting, month planning meeting, and the like, the theme information may be set according to the user requirement, which is not limited in this embodiment. The setting of the theme information can facilitate the user of the video network terminal to identify the electronic whiteboard with different themes. Similarly, the sharing server may set a unique identifier for the electronic whiteboard according to the identifier information included in the request for creating the electronic whiteboard, where the identifier may be any identifier information set by the user of the video networking terminal 1, and may be specific encoding information, such as 001, 002 and the like, for uniquely identifying the identity information of the electronic whiteboard, and the specific encoding manner may be set according to a requirement, which is not limited in this embodiment. The setting of the mark can be used for distinguishing different electronic whiteboards, and when more electronic whiteboards are created, the sharing server can manage and maintain the electronic whiteboards conveniently. Similarly, the sharing server may set a unique password for the electronic whiteboard according to the password information included in the request for creating the electronic whiteboard, where the password is used to verify the identity information of the video network terminal accessing the electronic whiteboard when other video network terminals access the electronic whiteboard. For example, after receiving the request for creating an electronic whiteboard from the internet of things terminal 1, the sharing server sets a corresponding password for the electronic whiteboard according to the password information in the request for creating the electronic whiteboard. When the video network terminal 2 needs to access the electronic whiteboard, a password set by the video network terminal 1 needs to be input (the password is notified to a user of the video network terminal 2by the user of the video network terminal 1, and the password is input by the user when the video network terminal 2 accesses the electronic whiteboard), so that the electronic whiteboard can be accessed. The password setting can limit the access to the video network terminal of the electronic whiteboard, and can keep secret for the sharing process of the electronic whiteboard. Similarly, the sharing server may set the number of sharing people for the electronic whiteboard according to the number of sharing people included in the request for creating the electronic whiteboard, where the number of sharing people is used to limit the number of accessing people for the electronic whiteboard, for example, the number of accessing people for the electronic whiteboard may be set to 10, which means that the number of accessing people for the electronic whiteboard is at most 10, and at this time, when the number of accessing people for the electronic whiteboard exceeds 10, the sharing server limits the access of other video network terminals exceeding 10 to the electronic whiteboard. The number of the shared people can limit the number of the video network terminals accessed to the electronic whiteboard, and the problem that the data transmission rate is low in the sharing process of the electronic whiteboard is solved when the number of the video network terminals accessed to the electronic whiteboard is too large.

It should be noted that, the sharing server may establish an electronic whiteboard corresponding to each request for creating an electronic whiteboard according to each request for creating an electronic whiteboard sent by each video network terminal. For example, the sharing server may establish an electronic whiteboard corresponding to the request for creating an electronic whiteboard according to the request for creating an electronic whiteboard sent by the terminal 1 of the video network, and set parameters such as a corresponding theme, a corresponding identifier, a corresponding password, and the number of sharing persons for the electronic whiteboard. Similarly, the sharing server may establish an electronic whiteboard corresponding to the request for creating an electronic whiteboard sent by the video network terminal 2 according to the request for creating an electronic whiteboard sent by the video network terminal 2, and set parameters such as a corresponding theme, a corresponding identifier, a corresponding password, a number of sharing people, and the like for the electronic whiteboard. In this embodiment, the number of creating the electronic whiteboard is not particularly limited.

And step 604, sending the electronic whiteboard to the first video network terminal.

In this embodiment, after the sharing server creates the electronic whiteboard, the electronic whiteboard may be sent to the first video networking terminal, and the first video networking terminal is instructed to complete creating the electronic whiteboard, so that the first video networking terminal initializes the local electronic whiteboard page. The electronic whiteboard page is used for receiving data input by a user of the first video network terminal, and meanwhile, the data input by other users of the video network terminals accessing the electronic whiteboard through other video network terminals can be displayed. For example, with reference to fig. 5 in combination with the examples in steps 601 to 603, after the electronic whiteboard is created, the sharing server may send the electronic whiteboard to the video network terminal 1, and after the video network terminal 1 receives the electronic whiteboard, initialize the local electronic whiteboard page to share the electronic whiteboard with other video network terminals accessing the electronic whiteboard.

Step 605, receiving a shared electronic whiteboard request sent by a second video network terminal, where the second video network terminal is a video network terminal of a second streaming media server of the at least two streaming media servers and is a video network terminal that logs in to the shared server using second information of the second video network terminal.

In the embodiment of the present invention, after the sharing server creates the electronic whiteboard, the sharing server may send the relevant information of the electronic whiteboard to all the video network terminals logging in the sharing server, where the relevant information of the electronic whiteboard includes, for example, the name and the identifier of the electronic whiteboard, the date when the electronic whiteboard was created, whether to set a password for the electronic whiteboard, and other information. For example, with reference to the examples in step 601 to step 604, after the sharing server creates an electronic whiteboard according to the electronic whiteboard creation request sent by the terminal 1 of the video network, information such as the theme and the identifier of the electronic whiteboard may be sent to the terminal 2 of the video network that has logged in the sharing server. The terminal 2 of the video network may select the electronic whiteboard according to the information such as the theme and the identifier of the electronic whiteboard sent by the sharing server, and send a request for sharing the electronic whiteboard to the sharing server.

The second streaming media server is any streaming media server different from the first streaming media server, and the second video network terminal is a video network terminal accessed to the second streaming media server. For convenience of understanding, in this embodiment, the streaming media server 2 is taken as a second streaming media server, and the video network terminal 2 accessing the streaming media server 2 is taken as a second video network terminal for example. Referring to fig. 5, the terminal 2 of the video network may log in the streaming server 2 and the sharing server, respectively, through the second account and the password. After the video network terminal 2 logs in the sharing server through the second account and the password, the sharing server may receive a shared electronic whiteboard request sent by the video network terminal 2, where the shared electronic whiteboard request may include a theme and an identifier of an electronic whiteboard to be shared.

And 606, sharing the electronic whiteboard to the second video network terminal according to the electronic whiteboard sharing request.

In the implementation of the invention, after receiving the shared electronic whiteboard request, the sharing server analyzes the shared electronic whiteboard request, determines the theme and the identifier included in the shared electronic whiteboard request, and can share the electronic whiteboard corresponding to the theme and the identifier to the second video network terminal. For example, with reference to fig. 5 in combination with the examples in steps 601 to 605, the sharing server receives a shared electronic whiteboard request sent by the video network terminal 2, determines that the electronic whiteboard created by the video network terminal 1 needs to be shared by the video network terminal 2 according to the theme and the identifier included in the shared electronic whiteboard request, at this time, the sharing server sends the corresponding electronic whiteboard to the video network terminal 2, and after the video network terminal 2 receives the electronic whiteboard sent by the sharing service, initializes a local electronic whiteboard page. At this time, the video network terminal 1 and the video network terminal 2 both initialize the local electronic whiteboard, and users of the video network terminal 1 and the video network terminal 2 can perform operations such as document online demonstration, editing, annotation and the like through the initialized local electronic whiteboard respectively. The user of the video network terminal 1 can input information such as characters, pictures and labels through the local electronic whiteboard page, the sharing server can synchronize data input by the video network terminal 1 to the local electronic whiteboard page of the video network terminal 2, and similarly, the sharing server can synchronize data input by the video network terminal 2 to the local electronic whiteboard page of the video network terminal 1, so that the electronic whiteboard sharing of the video network terminal 1 and the video network terminal 2 is realized.

In this embodiment, the sharing server obtains second information of the respective video network terminals of the at least two streaming media servers according to the stored first information of the respective at least two streaming media servers, receives an electronic whiteboard creating request sent by the first video network terminal of the first streaming media server, creates an electronic whiteboard on the sharing server according to the electronic whiteboard creating request, sends the electronic whiteboard to the first video network terminal, receives a shared electronic whiteboard request sent by the second video network terminal of the second streaming media server, and shares the electronic whiteboard with the second video network terminal according to the shared electronic whiteboard request, thereby implementing electronic whiteboard sharing between the first video network terminal of the first streaming media server and the second video network terminal of the second streaming media server. The sharing server acquires the second information of the video network terminal accessed to each streaming media server, allows the video network terminal to log in the sharing server through the second information, and can realize electronic whiteboard sharing among the video network terminals accessed to different streaming media servers.

Referring to fig. 7A, fig. 7A shows a flowchart of steps of a second embodiment of the electronic whiteboard sharing method according to the embodiment of the present invention, which may specifically include the following steps:

step 701, the sharing server receives first information of at least two streaming media servers input by a user, and stores the first information.

In this embodiment, for example, as described with reference to fig. 5 and fig. 7, a user may configure first information of the streaming media server 1 and the streaming media server 2 on the shared server, for example, the user configures the first information of the streaming media server 1 and the streaming media server 2 on the shared server through a configuration interface on the shared server, that is, the user may input the first information of the streaming media server 1 and the streaming media server 2 through the configuration interface, so that the shared server may receive and store the first information of each of the at least two streaming media servers input by the user. For example, referring to fig. 5, the user may input the first information of the streaming server 1 and the streaming server 2 to the sharing server, and the sharing server may receive the first information input by the user and store the first information. The sharing server can communicate with the streaming media server through the first information to acquire second information of the video network terminal stored in the streaming media server. Specifically, the process of acquiring the second information of the terminal of the video network may refer to step 601, which is not described herein again.

Step 702, the sharing server obtains second information of the respective video network terminals of the at least two streaming media servers according to the stored first information of the respective at least two streaming media servers.

This step is the same as step 601, and step 601 may be referred to for understanding step 702, which is not described herein again.

Step 703, the sharing server receives a first login request sent by the first video network terminal.

In this embodiment, the first video network terminal may be a video network terminal corresponding to any one of the second information, among all the second information acquired by the sharing server from the first streaming media server. Because the sharing server has already obtained the second information of the first video network terminal, the sharing server can confirm the identity of the first video network terminal through the second information, so that the first video network terminal can log in the sharing server through the second information to establish communication connection with the sharing server.

For example, referring to fig. 5, with reference to the example in step 601 to step 606, describing step 703, the sharing server may receive a first login request sent by the video network terminal 1, where the first login request may include a first account and a password in the second information of the video network terminal 1.

Optionally, before sending the first login request to the sharing server, the first video network terminal may send a data request to the sharing server, where the data request is used to obtain first information of the multiple streaming media servers stored in the sharing server, and select the first information of the first streaming media server from the multiple first information, and then the first video network terminal may send the first login request to the sharing server and the first streaming media server at the same time, and is used to simultaneously login the first streaming media server and the sharing server.

For example, referring to fig. 7B and 7C, fig. 7B is a schematic diagram of a login interface for acquiring first information according to an embodiment of the present invention, fig. 7C is a schematic diagram of a login interface for inputting second information according to an embodiment of the present invention, and with reference to the example in step 601 to step 606, before sending the first login request to the sharing server, the terminal 1 of the video network may input the IP address of the sharing server in the login interface (refer to fig. 7B) for acquiring the first information: 58.30.9.12, sending a data request to the sharing server (for example, by clicking the triangle button in fig. 7B to send the data request to the sharing server), acquiring the IP address of the streaming server 1 returned in the sharing server: 10.1.24.32 and the IP address of the streaming server 2: 10.1.24.33, the IP address of the streaming server 1 is selected from the IP addresses of the streaming server 1 and the streaming server 2, and after the storage is clicked, the user enters a login interface where the second information can be input (see FIG. 7C). The video network terminal 1 receives a first account and a password of the video network terminal 1, which are input by a user on a login interface for inputting second information, and after the user clicks login, the video network terminal 1 can send a first login request comprising the first account and the password to the streaming media server 1 and the sharing server respectively for logging in the sharing server and the streaming media server 1 respectively.

In this embodiment, the first video network terminal may send the first login request to the corresponding streaming media server while sending the first login request to log in the shared server, so as to log in the streaming media server. The first video network terminal can simultaneously log in the sharing server and the streaming media server through the second information, so that the first video network terminal can share the electronic whiteboard with the second video network terminal through the sharing server while acquiring the media stream from the streaming media server.

Step 704, the sharing server receives a second login request sent by the second video network terminal.

In this embodiment, the second video network terminal may be a video network terminal corresponding to any one of the second information obtained by the sharing server from the second streaming server. Because the sharing server has already obtained the second information of the second video network terminal, the sharing server can determine the identity of the second video network terminal through the second information, so that the second video network terminal can log in the sharing server through the second information to establish communication connection with the sharing server. The process of the sharing server receiving the second login request sent by the second video network terminal is the same as the process of receiving the first login request sent by the first video network terminal, and details are not repeated here.

Similarly, before sending the second login request to the sharing server, the second video network terminal may send a data request to the sharing server, where the data request is used to obtain first information of the multiple streaming media servers stored in the sharing server, select the second streaming media server from the multiple first information, and send the first login request to the sharing server and the second streaming media server at the same time, where the first login request is used to log in the second streaming media server and the sharing server at the same time. The process of the second video network terminal logging in the sharing server and the streaming media server at the same time is the same as that of the first video network terminal, and is not described herein again.

Step 705, if there is information consistent with the second information of the first video network terminal and information consistent with the second information of the second video network terminal in the second information of the respective video network terminals of the at least two streaming media servers acquired by the sharing server, logging in the first video network terminal and the second video network terminal to the sharing server.

In the embodiment of the invention, the sharing server acquires and stores the second information of the video network terminal which can access the streaming media server from the streaming media server, and after the sharing server receives the login request, if the second information included in the login request is consistent with any second information stored by the sharing server, the video network terminal which sends the login request is allowed to access the sharing server.

For example, with reference to the examples in step 601 to step 606, and in step 701 to step 704, the sharing server obtains and stores the second information of the video network terminal 1 and the video network terminal 2 from the streaming server 1 and the streaming server 2, respectively. When the sharing server receives a login request sent by the video networking terminal 1, the login request is analyzed, a first account and a password in second information included in the login request are determined, and if the first account and the password are consistent with a first account and a password stored by the sharing server, the video networking terminal 1 is allowed to log in the sharing server. Similarly, after the shared server receives the login request sent by the video network terminal 2, if the second account and the password in the second information included in the login request are consistent with the stored second account and password, the video network terminal 2 is allowed to log in the shared server.

Step 706, the first video network terminal sends a request for creating an electronic whiteboard to the sharing server.

In this embodiment, the first video network terminal logs in the sharing server, and after establishing a communication connection with the sharing server, may send a request for creating an electronic whiteboard to the sharing server, so that the sharing server creates an electronic whiteboard according to the request for creating an electronic whiteboard.

Optionally, the first video network terminal may further send a media stream request to the first streaming media server, so that the first streaming media server sends the media stream to the first video network terminal according to the media stream request.

The first video network terminal can receive the media stream sent by the first streaming media server and play the media stream on the first video network terminal.

For example, with reference to the example in steps 701 to 704, referring to fig. 5, after the video network terminal 1 logs in the streaming media server 1 and the sharing server at the same time, it may send a media stream request to the streaming media server 1, so as to obtain media streams provided by the streaming media server 1, such as live video, video monitoring, and video conference. The streaming media server 1 responds to the media stream request of the video network terminal 1, and provides the corresponding media stream to the video network terminal 1, and the video network terminal 1 can receive the media stream provided by the streaming media server 1 and display and play the media stream.

And step 707, the sharing server receives an electronic whiteboard creating request sent by the first video network terminal.

This step is the same as step 602, and step 602 can be referred to for understanding step 706, which is not described herein again.

Step 708, the sharing server creates an electronic whiteboard on the sharing server according to the request for creating the electronic whiteboard.

This step is the same as step 603, and step 603 may be referred to for understanding step 707, which is not described herein again.

And step 709, the sharing server sends the electronic whiteboard to the first video network terminal.

The process of the sharing server sending the electronic whiteboard to the first video network terminal is the same as step 604, and is not described herein again.

And step 710, the first video network terminal receives the electronic whiteboard sent by the sharing server, and displays the electronic whiteboard on the first video network terminal.

In this embodiment, the sharing server sends a request for creating an electronic whiteboard according to the first video network terminal, and after creating the electronic whiteboard, the created electronic whiteboard may be sent to the first video network terminal. The first video network terminal can receive the created electronic whiteboard sent by the sharing server and initialize the local electronic whiteboard page according to the electronic whiteboard sent by the sharing server.

For example, with reference to the example in step 601 to step 606, after receiving the electronic whiteboard sent by the sharing server, the video network terminal 1 initializes the local electronic whiteboard page.

And 711, receiving the shared electronic whiteboard request sent by the second video network terminal by the shared server.

In the embodiment of the invention, after the sharing server creates the electronic whiteboard, the sharing server can send the relevant information of the created electronic whiteboard to all video network terminals logging in the sharing server. For example, with reference to the examples in step 601 to step 606, after the sharing server creates an electronic whiteboard according to the electronic whiteboard creation request sent by the terminal 1 of the video network, the sharing server may send information such as the theme and the identifier of the electronic whiteboard to the terminal 2 of the video network. The terminal 2 of the video network may select the electronic whiteboard according to the information such as the theme and the identifier of the electronic whiteboard sent by the sharing server, and send a request for sharing the electronic whiteboard to the sharing server.

Optionally, the second video network terminal may further send a media stream request to the second streaming server, so that the streaming server sends the media stream to the second video network terminal according to the media stream request.

The second video network terminal can receive the media stream sent by the streaming media server and play the media stream on the second video network terminal.

The process of the second video network terminal obtaining the media stream from the second streaming media server is the same as that of the first video network terminal, and is not described herein again.

And 712, the sharing server shares the electronic whiteboard with the second video network terminal according to the request of sharing the electronic whiteboard.

The process of sharing the electronic whiteboard to the second video network terminal by the sharing server according to the request of sharing the electronic whiteboard is the same as the step 606, and details are not described herein.

In this embodiment, the sharing server receives respective first information of at least two video networking terminals input by a user, stores the first information, acquires second information of the video networking terminals accessing the streaming media server from the at least two streaming media servers according to the first information, receives an electronic whiteboard creating request sent by the first video networking terminal of the first streaming media server, creates an electronic whiteboard on the sharing server according to the electronic whiteboard creating request, sends the electronic whiteboard to the first video networking terminal, receives a shared electronic whiteboard request sent by the second video networking terminal of the second streaming media server, and shares the electronic whiteboard with the second video networking terminal according to the shared electronic whiteboard request, thereby implementing electronic whiteboard sharing between the first video networking terminal and the second video networking terminal.
