If the internet terminal does not receive the login response, the identity information of the internet terminal is illegal, and therefore the communication connection with the streaming media server cannot be established.

In actual use, the streaming media server searches whether a corresponding table entry comprising the streaming media account and the login password exists in a stored corresponding relation between the streaming media account and the password; if the corresponding table entry comprising the streaming media account and the login password exists, determining that the streaming media account and the login password are legal, and sending a login response to the internet terminal for informing the internet terminal of successful login; and if the corresponding table entry comprising the streaming media account and the login password does not exist, determining that the streaming media account and the login password are illegal, and not sending a login response to the Internet terminal.

Optionally, the plug-in provides an input box for inputting the authentication information on the target page after being started; the step 103 further includes:

and the Internet terminal acquires the identity authentication information from the input box of the plug-in.

That is, in the embodiment of the present invention, a login request for requesting to log in the streaming media server is generated after being input by the input box provided by the plug-in, where the login request includes the identity information of the internet terminal, and then the content in the input box is sent as a login request to the streaming media server for authentication by the plug-in.

In actual use, the plug-in also provides a login button after being started for initiating a login request. When the login button is triggered, the browser sends the content of the input frame to a streaming media server as a login request, and then the streaming media server performs authentication.

Optionally, the multimedia device includes a camera, a microphone and a speaker, and the step 104 specifically includes steps 411 to 412.

Optionally, the step 105 specifically includes steps 511 to 512.

Step 511, if the invite signaling is a first invite signaling, the internet terminal sends the first call number data to the streaming media server via the plug-in, and does not receive second call number data forwarded by the streaming media server.

In this step, the first invite signaling is a signaling that the internet terminal needs to join the conference and serve as a speaker, and if the internet terminal receives the first invite signaling forwarded by the streaming media server, it indicates that the internet terminal needs to participate in the conference as a speaker, so that the internet terminal sends the first call data to the streaming media server via the plug-in, and then the streaming media server transfers the first call data into the video networking data and sends the video networking data to the video networking core server, and then the video networking core server sends the video networking data to the video networking terminals participating in the conference, so that the video networking terminals participating in the conference play the video data and the audio data of the internet terminal side at the video networking terminal side. Meanwhile, in this step, the internet terminal does not receive the second call number data forwarded by the streaming media server, that is, the streaming media server does not receive the call data at the other participating terminals at this time. At this time, the internet terminal is a speaking party, and the other terminals are audience parties, so that the internet terminal does not need to acquire video data, namely audio data, of the other terminal sides, and therefore the internet terminal can not receive call data of the other terminals participating in the conference any more.

Step 512, if the invite signaling is a second invite signaling, the internet terminal receives, via the plug-in, second session number data forwarded by the streaming media server, and plays the second session data on the target page without sending the first session data.

In this step, the second invite signaling is a signaling that the internet terminal needs to join the conference and serves as an audience, and if the internet terminal receives the second invite signaling forwarded by the streaming media server, it indicates that the internet terminal needs to serve as a stop to participate in the conference, so that the internet terminal obtains the second communication data from the streaming media server via the plug-in. The second communication data is obtained by sending the video networking terminal which is currently used as a speaking party to the streaming media server and then transferring the video networking terminal to the streaming media server to be the internet data. Therefore, the video data and the audio data of the current chairman side can be played on the internet terminal side. Meanwhile, in this step, the internet terminal does not receive the second call number data forwarded by the streaming media server, that is, the streaming media server does not send the first call data any more at this time. At this time, on the internet terminal audience side, other participating terminals do not need to acquire the current video data and audio data of the internet terminal, so that the streaming media server does not need to receive the first call data at the internet terminal.

Preferably, after the plug-in is started, the internet terminal displays a first screen and a second screen on the target page via the plug-in. Optionally, the first picture is set larger than the second picture.

Accordingly, the step S511 further includes:

and if the invitation signaling is the first invitation signaling, the internet terminal displays the video pictures acquired by the camera on the first picture and the second picture.

Namely, when the internet terminal is required to be used as a speaking party, the internet terminal displays the video pictures of the internet terminal side on both the two pictures of the target page through the plug-in.

Correspondingly, the step S512 further includes:

if the invitation signaling is a second invitation signaling, the internet terminal plays audio data in the second communication data through the loudspeaker and displays video data in the second communication data in a first picture; and displaying the video picture acquired by the camera on the second picture.

When the internet terminal is needed to be used as a listener, the internet terminal displays a video picture of a current speaker on a first picture of a target page through a plug-in, simultaneously plays the sound of the speaker through a loudspeaker, and continuously displays a video picture of the internet terminal side on a second picture.

In a more preferred embodiment of the present invention, the internet terminal further comprises a codec;

the step 511 specifically includes:

encoding the first call data by using the codec;

sending the data after the coding processing to the streaming media server;

the step 512 specifically includes:

receiving second communication data from the streaming media server, and decoding the second communication data by using the coder and the decoder;

and playing the decoded data on the target page.

In the embodiment of the invention, when an internet terminal participates in a conference as a speaking party, first coding processing needs to be performed on first call data acquired through a plug-in, then a data cylinder deactivation TCP protocol after coding processing is sent to a streaming media server, and then the streaming media server is transferred into view networking data and then sent to a view networking terminal participating in the conference; when the internet terminal participates in a conference as an audience, the streaming media server is required to firstly receive the video networking data sent by the video networking terminal as a speaking party and convert the data into second communication data serving as an internet protocol, the internet data is firstly sent to the network equipment of the internet terminal and then decoded by the coder and decoder, then the plug-in can utilize the video data in the decoded data and display the image in a target page, and utilize the plug-in to read the audio data in the decoded data and play the audio data by the loudspeaker.

The codec server may encode video data in the first call data received from the internet terminal into an H264 format and encode audio therein into an AAC format.

Correspondingly, before the video network terminal plays the video network data forwarded by the protocol conversion server, decoding processing is also required; before the video network terminal sends the video data of the video network terminal side to the coordination server, the video data of the video network terminal side also needs to be coded and encoded to compress the data, so as to reduce the use amount of network bandwidth and facilitate data transmission.

Referring to fig. 2, fig. 2 shows a specific communication flow of the video call method provided by the embodiment of the present invention, when a PC 10 wants to participate in a video networking conference, a web server 20 is accessed by a PC browser to obtain a target page, then an IE plugin is triggered and started through the page, a login request including the identity information of the PC 10 is initiated through the IE plugin, and then the login request is verified by a streaming media server 30, and if the streaming media server 30 receives an invitation signaling including the identity information of the PC 10 sent by a video networking core server 40, the streaming media server 20 pulls the PC into the video networking conference through the IE plugin.

When the invitation signaling is a first invitation signaling, the PC terminal 10 encodes first call data acquired by the multimedia device by using the IE plugin and then sends the encoded first call data to the streaming media server 30, then the streaming media server 30 performs video networking protocol conversion into video networking data, and then sends the video networking data to the video networking core server 40, and further the video networking core server 40 sends the video networking data to the video networking terminals participating in the conference; when the invite signaling is the second invite signaling, the video network core server 40 performs internet protocol conversion on the encoded video network data sent by the video network terminal as the speaking party through the streaming media server 30 to obtain second communication data, the streaming media server 30 sends the second communication data to the PC terminal 10 for decoding, and then the decoded data is played through the IE plug-in.

In summary, in the method for performing a terminal conference according to the embodiment of the present invention, by using the feature that a browser supports a plug-in, when an internet terminal accesses a web server through the browser, an obtaining target page including a preset script is displayed on the browser, the internet terminal starts the plug-in according to the preset script, initiates a login request to the media server through the plug-in, and receives a login response to the login request, and if the internet terminal receives an invite signaling forwarded by the streaming media server, the internet terminal executes the pre-installed plug-in through the browser, obtains first call data from the multimedia device by using the plug-in, and sends the first call data to the streaming media server, or receives second call data from the streaming media server, and playing the second communication data on the target page, so that the Internet terminal can participate in the video conference of the video networking terminal by using a browser.

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;

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.

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.
