Products among different protocols in the prior art cannot be matched, so that barriers are generated among products of different protocols of the same type, and communication among terminals of different protocols of different types and different coding formats cannot be performed.
To solve this problem, in the embodiment of the present invention, a first transmission data stream sent by a first terminal is received, where the first transmission data stream is sent by the first terminal to a second terminal, and a first communication protocol corresponding to the first terminal is different from a second communication protocol corresponding to the second terminal; acquiring a first communication protocol and first transmission data stream configuration information corresponding to the first terminal; decoding the first transmission data stream according to the first communication protocol and the first transmission data stream configuration information, and determining a multimedia data stream; acquiring a second communication protocol and second transmission data stream configuration information corresponding to the second terminal; encoding the multimedia data stream according to the second transmission data stream configuration information, and converting the encoded multimedia data stream into a second transmission data stream according to the second communication protocol; and sending the second transmission data stream to the second terminal.
According to the embodiment of the invention, the transmission data streams of different communication protocols are converted into the transmission data streams of opposite-end communication protocols according to the communication protocols and the transmission data stream configuration information between the terminals of different communication protocols, and the terminals of different communication protocols can communicate with each other under the condition of not modifying any configuration by the communication protocol conversion and the transmission data stream configuration information conversion, so that the interconnection and the intercommunication of the different terminals of different protocols are realized.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for implementing communication between terminals with different protocols according to the present invention is applied to an apparatus for implementing communication between terminals with different protocols, which may specifically include the following steps:
step S110, receiving a first transmission data stream sent by a first terminal, wherein the first transmission data stream is sent to a second terminal by the first terminal, and a first communication protocol corresponding to the first terminal is different from a second communication protocol corresponding to the second terminal;
in particular, the more common protocol type of terminal equipment currently in use is the internet protocol (Internet Protocol, IP), and there are also many independently self-developed terminal communication protocols, different protocol types being unable to communicate. In addition, audio and video encoding and decoding are of various types, and only the same type of audio and video encoding and decoding can be used for communication, normal audio and video pictures are displayed, and different encoding and communication have various problems such as black screen.
When terminals of different protocols need to communicate, a transmitting end (denoted as a first terminal) transmits a transmission data stream (denoted as a first transmission data stream) to a receiving end (denoted as a second terminal), wherein the first transmission data stream can be an audio stream or a video stream, and the audio stream or the video stream is encapsulated by the first terminal according to the communication protocol type of the first terminal and is directly transmitted to the second terminal, so that the second terminal cannot analyze.
In order to solve this problem, a device for implementing communication between terminals with different protocols (hereinafter referred to as an implementation device for short) may acquire a first transmission data stream sent from a first terminal to a second terminal, process the first transmission data stream, and then send the first transmission data stream to the second terminal, so that the second terminal can analyze the transmission data stream, and implement 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, a first communication protocol and first transmission data stream configuration information corresponding to the first terminal are obtained;
specifically, after the implementation device obtains a first transmission data stream to be sent to the second terminal by the first terminal, the implementation device obtains a first communication protocol corresponding to the first terminal and first transmission data stream configuration information. The configuration information of the first transmission data stream may be information such as format, sampling rate, resolution, frame rate, code rate, etc. of the first transmission data stream.
The implementation device can provide an interface for inputting information for the user, the user manually inputs the first communication protocol and the first transmission data stream configuration information corresponding to the first terminal, and after submitting, the implementation device obtains the first communication protocol and the first transmission data stream configuration information corresponding to the first terminal.
The implementation device can also acquire the identification information corresponding to the first terminal, such as an identity, and retrieve the identity of the existing terminal, the communication protocol and the transmission data stream configuration information database through the identity, and acquire the first communication protocol and the first transmission data stream configuration information corresponding to the first terminal from the identification information corresponding to the first terminal.
The implementation device can also send a test data packet to the first terminal before receiving the first transmission data stream sent by the first terminal, receive the test data packet returned by the first terminal, analyze the test data packet, analyze from each field, and obtain the first communication protocol and the first transmission data stream configuration information corresponding to the first terminal.
In practical applications, the implementation device may further obtain the first communication protocol and the first transmission data stream configuration information corresponding to the first terminal through other manners, which are not described herein in detail.
For example, the first terminal is an internet of view terminal, the second terminal is an IP terminal, the transmission data stream sent by the first terminal to the second terminal is an audio data stream, and the implementation device may acquire that the communication protocol of the first terminal is an internet of view protocol, where the configuration information of the audio data stream includes an audio coding format, and the coding format is specifically Opus, which is a lossy sound coding format, developed by xiph. Org foundation, and then standardized by IETF (internet engineering task force), where the objective is to use a single format to include sound and voice, and to be suitable for low-delay instant sound transmission on a network.
Still taking the internet of view as an example, if the transmission data stream sent by the first terminal to the second terminal is a video data stream, the implementation device may acquire that the communication protocol of the first terminal is the internet of view protocol, and the configuration information of the video data stream includes information such as an encoding format, resolution, frame rate, code rate and the like of the video data stream, where the encoding format specifically is: h265, resolution 2K, frame rate 60FPS, code rate 406KBPS.
Step S130, decoding the first transmission data stream according to the first communication protocol and the first transmission data stream configuration information, and determining a multimedia data stream;
Specifically, after obtaining a first communication protocol and first transmission data stream configuration information corresponding to a first terminal, the implementation device decapsulates the first transmission data stream according to the first communication protocol, and parses the decapsulated first transmission data stream according to the first transmission data stream configuration information to obtain a multimedia data stream.
Step S140, acquiring a second communication protocol and second transmission data stream configuration information corresponding to the second terminal;
specifically, the implementation device acquires a first communication protocol corresponding to the second terminal and second transmission data stream configuration information. The configuration information of the second transmission data stream may be information of format, sampling rate, resolution, frame rate, code rate, etc. of the second transmission data stream.
The implementation device can provide an interface for inputting information for the user, the user manually inputs the second communication protocol and the second transmission data stream configuration information corresponding to the second terminal, and after submitting, the implementation device obtains the second communication protocol and the second transmission data stream configuration information corresponding to the second terminal.
The implementation device can also acquire the identification information corresponding to the second terminal, such as an identity, and retrieve the identity of the existing terminal, the communication protocol and the transmission data stream configuration information database through the identity, and acquire the second communication protocol and the second transmission data stream configuration information corresponding to the second terminal from the identification information corresponding to the second terminal.
The implementation device can 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, analyze the test data packet, analyze from each field, and obtain the configuration information of the second communication protocol and the first transmission data stream corresponding to the second terminal.
In practical applications, the implementation device may further obtain the second communication protocol and the second transmission data stream configuration information corresponding to the second terminal through other manners, which are not described herein in detail.
For example, the first terminal is an internet of view 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, so that the implementation device can obtain that the communication protocol of the second terminal is an IP protocol, and the configuration information of the audio data stream includes an audio coding format, where the coding format is specifically G711A.
Still taking the internet of view as an example, if the transmission data stream sent by the first terminal to the second terminal is a video data stream, the implementation device may acquire that the communication protocol of the second terminal is an IP protocol, and the configuration information of the video data stream includes information such as an encoding format, resolution, frame rate, code rate, and the like of the video data stream, where the encoding format specifically is: h264, 1080P resolution, 30FPS frame rate, 326KBPS code rate.
Step S150, encoding the multimedia data stream according to the second transmission data stream configuration information, and converting the encoded multimedia data stream into a second transmission data stream according to the second communication protocol;
step S160, transmitting 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, the second terminal can directly acquire the information sent by the first terminal by using the second transmission data stream because the communication protocol and the transmission data stream configuration information of the second terminal are consistent with each other.
In a specific implementation, after the second terminal receives the second transmission data stream, the second terminal may further send a third transmission data stream to the first terminal, and after the implementation device obtains the third transmission data stream, the implementation device determines the multimedia data stream according to the second communication protocol of the second terminal and the third transmission data stream configuration information, determines the fourth transmission data stream according to the first communication protocol of the first terminal and the fourth transmission data stream configuration information, and sends the fourth transmission data stream to the first terminal, so as to implement a communication process between terminals with different communication protocols.
In the embodiment of the invention, the transmission data streams of different communication protocols are converted into the transmission data streams of opposite-end communication protocols according to the communication protocols and the transmission data stream configuration information between the terminals of different communication protocols, and the terminals of different communication protocols can communicate with each other under the condition of not modifying any configuration by the communication protocol conversion and the transmission data stream configuration information conversion, so that the interconnection and the intercommunication of the different terminals of different protocols are realized.
In a preferred embodiment of the present invention, said decoding said first transport data stream according to said first communication protocol and first transport data stream configuration information, determining a multimedia data stream, comprises:
analyzing the first transmission data stream according to the first communication protocol, and determining a first coding data stream;
and decoding the first coded data stream according to the first transmission data stream configuration information, and determining the multimedia data stream.
Specifically, after the implementation device obtains the first transmission data stream, the first communication protocol and the first transmission data stream configuration information, the implementation device parses the first transmission data stream according to the first communication protocol, for example, decapsulates the first transmission data stream according to the first communication protocol, to obtain the first encoded data stream.
And then the realizing device decodes the first coded data stream according to the first transmission data stream configuration information to obtain a multimedia data stream, namely an original data stream to be transmitted by the first terminal.
In the embodiment of the invention, the transmission data stream is decoded through protocol decapsulation and configuration information, and the multimedia data stream is identified. And the second transmission data stream which can be identified by the second terminal can be converted according to the multimedia data stream, so that the interconnection and intercommunication of the terminals with different protocols are realized.
In a preferred embodiment of the present invention, the encoding the multimedia data stream according to the second transport data stream configuration information and converting the encoded multimedia data stream into the second transport data stream according to the second communication protocol includes:
encoding the multimedia data stream according to the second transmission data stream configuration information, and determining a second encoded data stream;
and encapsulating the second coded data stream according to the second communication protocol, and determining a second transmission data stream.
Specifically, after the implementation device obtains the multimedia data stream, the second communication protocol and the second data stream configuration information, the implementation device encodes the multimedia data stream according to the second transmission data stream configuration information to obtain a second indication data stream.
And then, the realization device encapsulates the second coded data stream according to the second communication protocol to obtain a second transmission data stream.
And then, the realization device sends the second transmission data stream to the second terminal, so as to realize interconnection and intercommunication between the first terminal and the second terminal.
For example, the first terminal is a video networking terminal, the second terminal is an IP terminal, the implementation device determines that the communication protocol of the first terminal is a video networking V2V protocol in advance, the configuration information of the audio data stream is an encoding format Opus, and the configuration information of the video data stream is: encoding format H265, resolution 2K, frame rate 60FPS, code rate 406KBPS. Meanwhile, the implementation device determines that the communication protocol of the second terminal is an IP protocol in advance, the configuration information of the audio data stream is in a coding format G711A, and the configuration information of the video data stream is: the coding format H264 has 1080P resolution, 30FPS frame rate and 326KBPS code rate.
When the first terminal sends a first audio-video stream to the second terminal, the implementation device analyzes the first audio-video stream according to the V2V protocol of the video network, converts the first audio-video stream with an audio coding format of Opus, a video coding format of H265, a resolution of 2k, a frame rate of 60FPS and a code rate of 406KBPS into a second audio-video stream conforming to an IP protocol with an audio coding format of G711A, a video coding format of H264, a resolution of 1080P, a frame rate of 30FPS and a code rate of 326KBPS, and then sends the second audio-video stream to the second terminal.
Similarly, when the second terminal sends the third audio-video stream to the first terminal, the implementation device analyzes the third audio-video stream according to the IP protocol, converts the third audio-video stream with the audio coding format of G711A, the video coding format of H264, the resolution of 1080P, the frame rate of 30FPS, the code rate of 326KBPS into the fourth audio-video stream with the audio coding format of opu, the video coding format of H265, the resolution of 2k, the frame rate of 60FPS, the code rate of 406KBPS and conforming to the V2V protocol of the video network, and then sends the fourth audio-video stream to the first terminal, so that the non-IP protocol terminal and the IP protocol terminal can communicate with each other without modifying any configuration, thereby realizing the requirement that the terminal and the IP protocol terminal of the non-IP protocol can communicate with each other under the conditions of different protocols, inconsistent encoding and decoding and non-uniform resolution.
In the embodiment of the invention, the transmission data streams of different communication protocols are converted into the transmission data streams of opposite-end communication protocols according to the communication protocols and the transmission data stream configuration information between the terminals of different communication protocols, and the terminals of different communication protocols can communicate with each other under the condition of not modifying any configuration by the communication protocol conversion and the transmission data stream configuration information conversion, so that the interconnection and the intercommunication of the different terminals of different protocols are realized.

Thereafter, the identification module 310 transmits the identified terminal information to the storage module 320, which stores all the identified terminal information and transmits to the configuration module 330.
After the configuration module 320 receives all the identified terminal information, configuration is performed, specifically, the user may perform configuration through a drop-down box:
(1) Clicking the name configuration item, popping up a drop-down frame, and displaying the latest identified terminal information on a first row;
(2) And selecting the V2V terminal, automatically completing other configuration items (such as a communication protocol, transmission data stream configuration information and the like), and clicking for storage.
(3) And opening the drop-down frame again, selecting the IP terminal, automatically completing other configuration items at the moment, and clicking for storage.
If clicking the "name configuration item" and popup the drop-down box, there are 2 ways to solve the problem that the latest identification information is not displayed:
(1) The step of identifying the terminal information to the configuration terminal information is repeated again until the configuration module 330 displays all the terminal information.
(2) Manual configuration is directly performed until the configuration module 330 displays all terminal information.
The configuration module 330 then sends the configuration information to the soft-programming soft-solution module 340.
The soft codec soft-decoder module 340 decodes and re-encodes the audio and video stream as follows:
a1, calling the IP terminal by using the V2V terminal at the moment, and sending an audio and video stream to the soft-editing soft-decoding module 340 by the terminal after signaling intercommunication;
a2, the soft coding and soft decoding module 340 decodes the video sent by the V2V terminal and recompiles the video into a real-time transmission audio/video stream with G711A, H coding format, 1080P resolution, 30FPS frame rate and 326KBPS code rate, and sends the real-time transmission audio/video stream to the IP terminal;
and A3, similarly, the soft coding and soft decoding module 340 can decode and recompile the printed video sent by the IP terminal, and send the real-time transmission audio/video stream with the Opus, H265 format, resolution of 2k, frame rate of 60FPS and code rate of 406KBPS format to the V2V terminal to realize video telephone communication. And the gateway equipment is used for realizing interconnection and interworking of different protocol terminals under different coding formats.
