The first transmission data stream is sent by the first terminal to the second terminal, and the first terminal corresponds to The first communication protocol is different from the second communication protocol corresponding to the second terminal; obtaining the first communication protocol and the first transmission data flow configuration information corresponding to the first terminal; according to the first communication protocol and the first Transmission data flow configuration information decodes the first transmission data stream to determine a multimedia data stream; obtains the second communication protocol and second transmission data flow configuration information corresponding to the second terminal; and according to the second transmission data flow configuration information Encoding the multimedia data stream, and converting the encoded multimedia data stream into a second transmission data stream according to the second communication protocol; sending the second transmission data stream to the second terminal.

Referring to Figure 1, there is shown a step flow chart of an embodiment of a method for realizing communication between terminals of different protocols according to the present invention. It is applied to a device for realizing communication between terminals of different protocols. Specifically, it may include the following steps:

Step S110: Receive the first transmission data stream sent by the first terminal. The first transmission data stream is sent by the first terminal to the second terminal. The first communication protocol corresponding to the first terminal is the same as the first communication protocol of the first terminal. The second communication protocols corresponding to the two terminals are different;

Specifically, the most commonly used terminal device protocol type currently is the Internet Protocol (IP), and there are also many independently developed terminal communication protocols. Different protocol types cannot communicate. In addition, there are many types of audio and video codecs. Only audio and video codecs of the same type can communicate and display normal audio and video pictures. Communication with different codecs will cause various problems such as black screens.

When terminals with different protocols need to communicate, the sending end (denoted as the first terminal) sends a transmission data stream (denoted as the first transmission data stream) to the receiving end (denoted as the second terminal). The first transmission data stream can be Audio stream or video stream, which is encapsulated by the first terminal according to the communication protocol type of the first terminal and sent directly to the second terminal, will cause the second terminal to be unable to parse.

In order to solve this problem, a device that implements terminal communication with different protocols (hereinafter referred to as the implementation device) can obtain the first transmission data stream sent by the first terminal to the second terminal, process the first transmission data stream, and then send it to the second terminal, so that the second terminal can parse the transmission data stream and realize communication between the first terminal and the second terminal.

For example, the first terminal may be a private protocol terminal, and the second terminal may be an IP terminal.

Step S120: Obtain the first communication protocol and first transmission data flow configuration information corresponding to the first terminal;

Specifically, after obtaining the first transmission data stream to be sent by the first terminal to the second terminal, the implementation device obtains the first communication protocol corresponding to the first terminal and the first transmission data stream configuration information.

For example, if the first terminal is a video networking terminal, the second terminal is an IP terminal, and the transmission data stream sent by the first terminal to the second terminal is an audio data stream, then the implementation device can obtain that the communication protocol of the first terminal is the video networking protocol. The configuration information of the audio data stream includes the audio encoding format. The encoding format is specifically Opus. Opus is a lossy sound encoding format developed by the Xiph.Org Foundation and later standardized by the IETF (Internet Engineering Task Force). The goal It is hoped that a single format can contain sound and speech and be suitable for low-latency real-time sound transmission on the network.

Still taking video networking as an example, the transmission data stream sent by the first terminal to the second terminal is a video data stream, then the implementation device can obtain that the communication protocol of the first terminal is the video networking protocol, and the configuration information of the video data stream includes video data. The encoding format, resolution, frame rate, code rate and other information of the stream. The encoding format is specifically: H265, the resolution is 2K, the frame rate is 60FPS, and the code rate is 406KBPS.

Step S130: Decode the first transmission data stream according to the first communication protocol and the first transmission data stream configuration information to determine the multimedia data stream;

Specifically, after the implementation device obtains the first communication protocol and the first transmission data flow configuration information corresponding to the first terminal, it decapsulates the first transmission data flow according to the first communication protocol, and parses the first transmission data flow according to the first transmission data flow configuration information. The encapsulated first transmission data stream is obtained as a multimedia data stream.

After submission, the implementation device obtains the second communication protocol corresponding to the second terminal. and second transport data stream configuration information.

The implementation device can also obtain the identification information corresponding to the second terminal, such as an identity identification, retrieve the existing terminal identity identification and communication protocol, and the transmission data flow configuration information database through the identity identification, and obtain the identification information corresponding to the second terminal to the second terminal. Corresponding second communication protocol and second transmission data stream configuration information.

The implementation device may also send a test data packet to the second terminal before receiving the first transmission data stream sent by the first terminal, receive the test data packet returned by the second terminal, parse the test data packet, analyze from each field, and obtain The second communication protocol and the first transmission data flow configuration information corresponding to the second terminal.

In actual applications, the implementation device may also obtain the second communication protocol and the second transmission data flow configuration information corresponding to the second terminal through other methods, which will not be described again here.

For example, if the first terminal is a video networking terminal, the second terminal is an IP terminal, and the transmission data stream sent by the first terminal to the second terminal is an audio data stream, then the implementation device can obtain that the communication protocol of the second terminal is the IP protocol, The configuration information of the audio data stream includes the audio encoding format, and the encoding format is specifically G711A.

Step S150: Encode the multimedia data stream according to the second transmission data stream configuration information, and convert the encoded multimedia data stream into a second transmission data stream according to the second communication protocol;

Step S160: Send the second transmission data stream to the second terminal.

Specifically, the implementation device encodes the multimedia data stream according to the second transmission data stream configuration information, converts the encoded multimedia data stream into the second transmission data stream according to the second communication protocol, and sends the second transmission data stream to the second terminal.

After the second terminal receives the second transmission data stream, since the communication protocol and transmission data stream configuration information of the second transmission data stream are consistent with that of the second terminal, the second terminal can directly use the second transmission data stream to obtain the second transmission data stream. Information sent by a terminal.

In a specific implementation, after the second terminal receives the second transmission data stream, it can continue to send the third transmission data stream to the first terminal. After the implementation device obtains the third transmission data stream, according to the second communication of the second terminal The protocol and the third transmission data stream configuration information determine the multimedia data stream, determine the fourth transmission data stream according to the first communication protocol and the fourth transmission data stream configuration information of the first terminal, and send the fourth transmission data stream to the first terminal, Realizes the communication process between terminals with different communication protocols.
