Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In view of the problems in the related art, the present application provides an audio/video data transmission method, in an audio/video communication scenario of a video network, a streaming media server is only responsible for establishing an end-to-end communication connection between two communication parties, and after the end-to-end communication connection between the two communication parties is established, the audio/video data is directly transmitted between the two communication parties through the established channel without passing through the streaming media server, so as to reduce the bandwidth pressure of the streaming media server, and further enhance the service processing performance of the streaming media server.

Fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the present application. In fig. 1, the streaming media server is in communication connection with the first terminal and the second terminal, and the streaming media server, the first terminal and the second terminal are all deployed in a video networking environment and perform communication interaction with each other through a video networking protocol.

Of course, the first terminal and/or the second terminal may be deployed in the video network, or may be deployed in the internet (fig. 1 only shows the case where the first terminal and/or the second terminal is deployed in the video network). When the terminals (the first terminal and/or the second terminal) are deployed in the internet, the protocol conversion server is required to be used as an intermediate bridge to establish a communication connection with the streaming media server. Illustratively, when the first terminal is deployed in the internet, the first terminal needs to establish a communication connection with the streaming media server through the protocol conversion server, and since the protocol conversion server supports the internet network card and the video network card, the first terminal can be in communication interaction with the first terminal through the internet protocol, and can also be in communication interaction with the streaming media server through the video network protocol.

Fig. 2 is a flowchart of an audio-video data transmission method according to an embodiment of the present application. The audio/video data transmission method provided by the present application will be described in detail with reference to fig. 2. The method can be applied to the first terminal in fig. 1, and specifically includes the following steps:

step S11: and sending a communication connection request to a streaming media server in communication connection with the first terminal, wherein the communication connection request is used for requesting to establish communication connection with a second terminal.

In this embodiment, the first terminal may establish a video communication connection with the second terminal, or may establish an audio communication connection with the second terminal. When the first terminal requests to establish the video communication connection with the second terminal, a request for establishing the video communication connection is sent to the streaming media server, and when the first terminal requests to establish the audio communication connection with the second terminal, a request for establishing the audio communication connection is sent to the streaming media server. For the convenience of describing the audio/video data transmission method of the present application, it is specifically described herein that the communication connection referred to in the following embodiments is a video communication connection.

Step S12: and receiving first communication data sent by the streaming media server, wherein the first communication data is communication data corresponding to the second terminal.

In this embodiment, the first communication data is used to establish an end-to-end communication connection with the second terminal.

Step S13: and establishing a first communication connection for end-to-end communication with the second terminal based on the first communication data.

In this embodiment, the first terminal may directly establish an end-to-end communication connection with the second terminal through the first communication data, that is: the first terminal can bypass the streaming media server to directly establish the communication connection with the second terminal.

In one embodiment, if the first terminal and the second terminal are both deployed in the video network, the first terminal may directly establish an end-to-end communication connection with the second terminal; in another embodiment, if the first terminal is deployed in the video network and the second terminal is deployed in the internet, the first terminal may establish an end-to-end communication connection with the second terminal through the protocol conversion server.

Step S14: and sending audio and video data to the second terminal based on the first communication connection.

In this embodiment, since the communication connection between the first terminal and the second terminal is an end-to-end communication connection, the first terminal may directly send the audio and video data to the second terminal through the end-to-end communication connection without going through the streaming media server.

Fig. 3 is a schematic process diagram of an audio-video data transmission method according to an embodiment of the present application. The above-described steps S11 to S14 will be exemplarily described with reference to fig. 3.

The terminal A is positioned in the Internet and is in communication connection with the streaming media server through the protocol conversion server, and the terminal B is positioned in the video network and is directly in communication connection with the streaming media server. When terminal a requests video communication with terminal B, a communication connection request is transmitted to the streaming server through the protocol conversion server. And after receiving the communication connection request, the streaming media server acquires the communication data corresponding to the terminal B and sends the communication data corresponding to the terminal B to the terminal A. After receiving the communication data corresponding to the terminal B, the terminal a sends a request for establishing an end-to-end communication connection with the terminal B to the protocol conversion server through the communication data corresponding to the terminal B, so that the protocol conversion server sends the request to the terminal B, and if the terminal B returns a response agreeing to establish a communication connection to the terminal a, the end-to-end communication connection between the terminal a and the terminal B is successfully established, specifically, the communication connection is formed by the terminal a, the protocol conversion server and the terminal B, as shown by a thick line part in fig. 3. And then, the terminal A can send the acquired audio and video stream to the terminal B through the established end-to-end communication connection.

By the audio and video data transmission method of the embodiment, when a first terminal requests to establish communication connection with a second terminal, communication data corresponding to the second terminal is firstly obtained through a streaming media server, then a request for establishing end-to-end communication connection is directly initiated to the second terminal according to the communication data corresponding to the second terminal, and after the establishment is successful, audio and video data are transmitted to the second terminal through the end-to-end communication connection. On one hand, the end-to-end communication connection is established between the terminals through the communication data acquired from the streaming media server, so that the end-to-end transmission of the audio and video data can be directly carried out between the terminals, namely the first terminal directly sends the audio and video data to the second terminal, the situation that the first terminal needs to transfer the audio and video data through the streaming media server in the related technology is avoided, and the efficiency of audio and video data transmission is improved. On the other hand, the streaming media server can establish end-to-end communication connection between the terminals by sending communication data to the terminals, so that end-to-end audio and video transmission can be performed between the terminals, and audio and video data transmission is not performed any more, thereby remarkably reducing the bandwidth pressure of the streaming media server, and enhancing the service processing performance of the streaming media server and the capability of coping with high concurrent audio and video communication services.

In the application, after a first terminal sends a communication connection request to a streaming media server, the streaming media server sends communication data corresponding to a second terminal to the first terminal, so that the first terminal actively establishes end-to-end communication connection with the second terminal; meanwhile, the communication data corresponding to the first terminal is also sent to the second terminal, so that the second terminal actively establishes end-to-end communication connection with the first terminal, and further bidirectional communication connection between the first terminal and the second terminal is realized.

Fig. 4 is a flowchart illustrating a further method for transmitting audio-video data according to an embodiment of the present application. Referring to fig. 4, in addition to the above-mentioned step S11-step S14, the audio-video data transmission method of the present application may further include the following steps:

step S15: and when receiving a second communication connection request sent by the second terminal, returning a response representing that the second communication connection request is approved to the second terminal so as to establish a second communication connection for end-to-end communication with the second terminal.

In this embodiment, the communication connection actively established between the first terminal and the second terminal is a first communication connection, and the first communication connection functions as: and transmitting the audio and video data generated by the first terminal to the second terminal. The communication connection established between the second terminal and the first terminal actively is a second communication connection, and the second communication connection has the following functions: and transmitting the audio and video data generated by the second terminal to the first terminal.

In this embodiment, after receiving the first communication connection request sent by the first terminal, the second terminal returns a response indicating approval of the first communication connection request to the first terminal, and then the first communication connection is established successfully. Similarly, after receiving the second communication connection request sent by the second terminal, the first terminal successfully establishes the second communication connection if a response indicating that the second communication connection request is granted is returned to the second terminal.

Step S16: and receiving audio and video data sent by the second terminal based on the second communication connection.

In this embodiment, after the second communication connection is successfully established, the second terminal may send the acquired audio/video stream to the first terminal through the second communication connection, that is: the first terminal can receive the audio and video data sent by the second terminal through the second communication connection.

By the audio and video data transmission method, the first terminal and the second terminal can actively request to establish end-to-end communication connection with the opposite terminal, so that bidirectional communication connection is established, audio and video bidirectional transmission is realized, interaction requirements of users in audio and video communication can be effectively met, and use experience of the users is enhanced.

With reference to the foregoing embodiments, in an implementation manner, an embodiment of the present application further provides a method for sending audio and video data, as shown in fig. 5. Fig. 5 is a flowchart illustrating a method for transmitting audio/video data according to an embodiment of the present application. Referring to fig. 5, the step S14 may include:

step S141: and obtaining the coding and decoding parameters of the second terminal from the first communication data.

Step S142: and processing the acquired audio and video data according to the coding and decoding parameters.

Step S143: and sending the processed audio and video data to the second terminal based on the first communication connection.

In the present embodiment, the codec parameters include video coding parameters and audio coding parameters. The frequency encoding parameters may include: video frame rate, video code rate, video resolution, video sampling rate, video sampling precision, video quality and the like. The audio coding parameters may include: audio code rate, audio sampling precision, audio quality, and the like.

In this embodiment, the first terminal may acquire the encoding and decoding capability of the second terminal according to the first communication data, and in order to ensure that the second terminal can decode successfully after receiving the audio and video data sent by the first terminal, after acquiring the audio and video data, the first terminal may encode the acquired audio and video data according to the encoding parameter of the second terminal, and then send the encoded audio and video data to the second terminal.

In practical implementation, the first terminal may set the encoding and decoding device according to the encoding and decoding parameters of the second terminal after obtaining the encoding and decoding parameters of the second terminal, so that the encoding and decoding device and the encoding and decoding device of the second terminal have the same encoding and decoding capabilities, and smooth transmission of audio and video data is ensured.

In this embodiment, when the first terminal requests to establish a communication connection with the second terminal, the first terminal may further obtain the encoding and decoding capabilities of the second terminal according to the first communication data, and then configure the encoding and decoding device of the first terminal as a device having the same encoding and decoding capabilities as the second terminal, so that the second terminal can successfully decode the audio and video data sent by the first terminal, and further ensure the smooth transmission of the audio and video data.

With reference to the foregoing embodiment, in an implementation manner, if the second terminal further establishes a second communication connection with the first terminal, the second terminal may further obtain the codec parameter of the first terminal from the second communication data, process the acquired audio/video data according to the codec parameter, and then send the processed audio/video data to the first terminal based on the second communication connection. Therefore, after the end-to-end communication connection is established between the first terminal and the second terminal, the encoding and decoding processing can be carried out on the audio and video data acquired by the first terminal and the second terminal according to the encoding and decoding parameters of the opposite terminal, and the smooth transmission of the audio and video data is further ensured.

In an implementation manner, with reference to the above embodiment, the present application further provides a method for establishing a first communication connection. Specifically, the step S13 may include:

In this embodiment, the first terminal obtains address information of the second terminal, such as a MAC address, a TCP port number, a UDP port number, and the like, from the first communication data after receiving the first communication data. And then, according to the address information, sending a communication connection request for establishing the first communication connection to the second terminal.

Accordingly, the second terminal obtains the address information of the first terminal, such as the MAC address, the TCP port number, the UDP port number, and the like, from the second communication data after receiving the second communication data. And then, according to the address information, sending a communication connection request for establishing a second communication connection to the first terminal.

In this embodiment, after receiving the communication connection request sent by the first terminal, the second terminal automatically returns a response agreeing to establish the first communication connection to the first terminal in a default state, or may return a response indicating whether to establish the first communication connection to the first terminal under the operation of the user on the side of the second terminal. Similarly, after receiving the communication connection request sent by the second terminal, the first terminal automatically returns a response agreeing to establish the second communication connection to the second terminal in a default state, or returns a response indicating whether to establish the first communication connection to the second terminal under the operation of the user on the side of the first terminal. This embodiment does not specifically limit this.

In this embodiment, the communication data (including the first communication data and the second communication data) carries address information of the opposite end, so that the first terminal and/or the second terminal can smoothly establish communication connection with the opposite end according to the address information of the opposite end, thereby realizing end-to-end transmission of audio and video data.

In combination with the above embodiment, in an implementation manner, after the step S13, the following steps may be further included:

In this embodiment, because the end-to-end communication connection is established between the first terminal and the second terminal, and no streaming media server is needed to participate in the subsequent audio/video data transmission process, after the first terminal determines that the first communication connection is successfully established, a message indicating that the first communication connection is successfully established may be sent to the streaming media server, so that the streaming media server releases the original communication connection with the first terminal, so as to reduce the bandwidth pressure of the streaming media server, and use the bandwidth resource for establishing the communication connection between other terminals, thereby enhancing the service processing performance of the streaming media server.

Accordingly, if a bidirectional communication connection is established between the first terminal and the second terminal, after the second terminal determines that the second communication connection is successfully established, a message indicating that the second communication connection is successfully established may be sent to the streaming media server, so that the streaming media server releases the original communication connection with the second terminal.

In this embodiment, after knowing that the first communication connection is successfully established, the streaming media server releases the original communication connection with the first terminal, thereby reducing the bandwidth pressure of the streaming media server and enhancing the service processing performance of the streaming media server.

The embodiment of the application also provides another audio and video data sending method, as shown in fig. 6. Fig. 6 is a flowchart illustrating a further method for transmitting audio-video data according to an embodiment of the present application.

Step S22: and sending first communication data corresponding to the second terminal to the first terminal so that the first terminal establishes a first communication connection for end-to-end communication with the second terminal according to the first communication data, and sending audio and video data to the second terminal through the first communication connection.

For the description of step S21-step S22, reference may be made to the foregoing description of step S11-step S14, and the description of the embodiments of the present application is not repeated herein.

With reference to the foregoing embodiment, in an implementation manner, the audio/video data sending method according to the present application may further include:

With reference to the foregoing embodiment, in an implementation manner, before step S21, the method for sending audio/video data according to the present application may further include the following steps:

In the embodiment, the first terminal and the second terminal support a video networking audio and video instant messaging protocol. The format of the video networking audio and video instant messaging protocol is shown in the following table:

in the video networking audio and video instant communication protocol, a version number, CRC check, a host name, a source address (namely a source IP address), a source MAC, a target address (namely a target IP address), a target MAC, a source TCP port, a target TCP port, a source UDP port and a target UDP port are header information of the protocol; the network type, the network bandwidth, the network adoption duration, the maximum network bandwidth and the minimum network bandwidth are the respective network information of two communicated terminals (a source terminal and a target terminal); the CPU model, the CPU size, the CPU utilization rate, the memory model, the memory size, the memory utilization rate, the display card model, the display card size and the display card utilization rate are the encoding and decoding capacity information of the current host; the video protocol, the video frame rate, the video code rate, the video resolution, the video sampling rate, the video sampling precision and the video quality are video coding and decoding parameter information of the current host; the audio protocol, the audio sampling rate, the audio sampling precision and the audio quality are the audio coding and decoding parameter information of the current host. In this embodiment, some devices need to adopt IP addressing (for example, terminals deployed in the internet), and some devices need to adopt MAC addressing (for example, terminals deployed in the video network), so the protocol needs to be provided with an IP address and a MAC address.

In this embodiment, each time the first terminal logs in the streaming media server, the first terminal obtains its own network information, codec capability information, video codec parameter information, and audio codec parameter information, carries the part of data in a login request, and sends the login request to the streaming media server based on an audio/video instant messaging protocol of the video network. After receiving the login request, the streaming media server analyzes the login request to obtain login information, and uses the network information of the first terminal, the coding and decoding capability information of the first terminal, the video coding and decoding parameter information of the first terminal and the audio coding and decoding parameter information of the first terminal in the login information as communication data corresponding to the first terminal, and stores the communication data in a database, wherein the format of the communication data is shown in the following table:

similarly, the second terminal obtains its own network information, codec capability information, video codec parameter information, and audio codec parameter information each time it logs in to the streaming media server, carries the part of data in the login request, and sends the login request to the streaming media server based on the video networking audio/video instant messaging protocol. After receiving the login request, the streaming media server analyzes the login request to obtain login information, obtains network information of the second terminal, coding and decoding capability information of the second terminal, video coding and decoding parameter information of the second terminal and audio coding and decoding parameter information of the second terminal from the login information, takes the part of information as communication data corresponding to the second terminal and stores the communication data in a database, wherein the format of the communication data is shown in the following table:

If a bidirectional communication connection needs to be established between the first terminal and the second terminal, the streaming media server obtains communication data corresponding to the first terminal, the second terminal is used as a target terminal, a target address, a target MAC, a target TCP port and a target UDP port in header information in the communication data are set, and after the setting is successful, the communication data corresponding to the first terminal is sent to the second terminal.

In this embodiment, the first terminal and the second terminal actively report their communication data to the streaming media server as backup data during login, so that the streaming media server automatically obtains the communication data corresponding to the second terminal and sends the communication data to the first terminal after receiving a request for establishing an end-to-end communication connection between the first terminal and the second terminal, and obtains the communication data corresponding to the first terminal and sends the communication data to the second terminal, so that the first terminal and the second terminal actively establish a communication connection with an opposite terminal according to the received communication data, and finally realize an end-to-end communication connection independent of the streaming media server, thereby accelerating transmission efficiency of audio and video data and reducing bandwidth pressure of the streaming media server.

The streaming media server is provided with a client online list, all current clients which successfully log in are displayed in the list, and the online client can select one client from all other online clients and initiate audio-video communication.

After the client A logs in the streaming media server, the streaming media server records communication data corresponding to the client A in the login information of the client A and returns a current client online list to the client A; similarly, after the client B logs in the streaming media server, the streaming media server records the communication data corresponding to the client B in the login information of the client B, and returns the current client online list to the client B. At this time, the client a can check that the client B is in the online state, the client B can check that the client a is in the online state, and audio and video communication can be initiated between the two parties.

Taking the example that the client A initiates audio and video communication to the client B, the user A selects the client B from the client online list, the client A generates a communication connection request according to an internet protocol, then sends the communication connection request to the monitoring access server, the monitoring access server encapsulates the communication connection request according to the video networking protocol, then sends the communication connection request to the streaming media server, the streaming media server analyzes the communication connection request to obtain communication data corresponding to the client B, and sends the data to the client A, and meanwhile, obtains the communication data corresponding to the client A, and sends the data to the client B. The client A establishes a first communication connection with the client B according to the communication data corresponding to the client B, and the client B establishes a second communication connection with the client A according to the communication data corresponding to the client A, so that the establishment of the bidirectional communication connection between the client A and the client B is successful.

And then, the client A and the client B can directly carry out bidirectional transmission of audio and video data through the established channel, wherein the monitoring access server is in communication interaction with the client A through an internet instruction and in communication interaction with the client B through a video networking instruction, so that the transmission of the audio and video data between the internet and the video networking is realized. In the process, the audio and video data can be directly transmitted between the client A and the client B, so that the transmission effect of the audio and video data can be remarkably accelerated and the bandwidth pressure of the streaming media server is reduced compared with the original transmission mode which needs the streaming media server as a transfer.

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.

Based on the above characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, following a protocol of the video network, when a first terminal requests to establish a communication connection with a second terminal, a streaming media server first obtains communication data corresponding to the second terminal, then directly initiates a request for establishing an end-to-end communication connection to the second terminal according to the communication data corresponding to the second terminal, and after the establishment is successful, transmits audio and video data to the second terminal through the end-to-end communication connection without passing through the streaming media server.
