Detailed Description
In order to make the technical solutions of the present application better understood, 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 only a part of the embodiments of the present application, and not all of the embodiments.

At present, in a video conference system, different conference sites can access a video conference through terminals, so that the video conference is held. Therefore, the terminal is the most important device of the meeting place, once the terminal fails, the meeting place can quit the video conference, and the terminal is difficult to recover in a short time in consideration of the complexity of troubleshooting, so that a conference accident is caused.
Therefore, in the method, a main terminal and a standby terminal need to be deployed in a meeting place, such as a target meeting place, and audio and video interfaces of the main terminal and the standby terminal respectively establish physical line connection with audio and video signal input and output equipment of the target meeting place through an audio and video matrix. When the video conference starts, the video conference can be added through the main terminal, and at the moment, the audio and video interface of the main terminal is communicated with the audio and video signal input and output equipment to form a first transmission channel, wherein the first transmission channel is used for transmitting audio and video signals generated in the video conference. In the process of carrying out the video conference through the main terminal, the main terminal is monitored to monitor whether the main terminal has a fault. If the active terminal is monitored to be in fault, an audio/video interface of the standby terminal is controlled to be communicated with the audio/video signal input/output equipment through the audio/video matrix to form a second transmission path, and the signal transmission path for transmitting the audio/video signals is switched from the first transmission path to the second transmission path, so that the video conference is continuously carried out through the standby terminal, and the normal operation of the video conference is ensured. By the method, when the terminal accessed to the video conference breaks down, the main equipment and the standby equipment can be seamlessly switched, so that the situation that the participating site exits from the video conference due to the fact that the terminal breaks down is avoided, and conference accidents are avoided. Moreover, due to the seamless switching, the participants can not feel the interruption of the picture and the sound, and the video conference experience is improved.
It should be noted that the method provided in the embodiment of the present application may be integrated on conference management software (conference management for short), and in a normal case, the conference management software may be installed on a server, and further, when a user, for example, a manager logs in the conference management software through a browser, the method may be implemented by the conference management software. Of course, in some cases, the conference management software may also be installed on a terminal, where the terminal may include, for example, a computer, a laptop, a tablet, and the like. The conference management software is used for managing the video conference, for example, monitoring whether a terminal joining the conference fails or not, so as to ensure normal operation of the video conference. The embodiment of the application mainly takes the example that the conference management software is installed on the server, and introduces the method for switching the audio and video signals.
The following describes in detail a method for switching audio and video signals provided in an embodiment of the present application with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a flow chart of a method of audio-video signal switching, the method comprising:
s101, monitoring the main terminal in the process of carrying out a video conference through the main terminal, and transmitting audio and video signals generated by the video conference through a first transmission path in the process of carrying out the video conference through the main terminal, wherein the first transmission path is formed by connecting an audio and video interface of the main terminal with audio and video signal input and output equipment to form a signal transmission path.
In the embodiment of the application, in order to ensure that the participating sites do not exit the video conference due to terminal failure and avoid conference accidents, a main terminal and a standby terminal can be deployed in each participating site. Taking any participating place (for example, a target participating place) as an example, a main terminal and a standby terminal are deployed in the target participating place, and audio and video interfaces of the main terminal and the standby terminal are respectively connected with audio and video signal input and output equipment of the target participating place through an audio and video matrix by physical lines.
The audio and video signal input and output equipment comprises audio and video signal input equipment and audio and video signal output equipment. The audio/video signal input device may be, for example, an audio/video signal acquisition device, and may include a microphone, a camera device, and the like; the audio-video signal output device may include, for example, a sound box, a display device, and the like.
When a video conference starts, the main terminal is added into the video conference, and at the moment, audio and video signals generated by the video conference are transmitted through a first transmission channel, wherein the first transmission channel is a signal transmission channel formed by connecting an audio and video interface of the main terminal with audio and video signal input and output equipment.
Although the standby terminal is not used at this time, in order to ensure that the switching can be performed in time once the active terminal fails, the standby terminal needs to be kept on-line and powered on.
In the process of carrying out the video conference through the main terminal, the server can monitor the main terminal. Specifically, the server may monitor the main terminal through the conference management software installed thereon. In the monitoring process, whether the main terminal is accessible on the network or not can be monitored, or whether a signal is input or output at an audio/video interface of the main terminal is monitored.
S102, if the main terminal is monitored to have a fault, controlling an audio and video interface of the standby terminal to be communicated with the audio and video signal input and output equipment through the audio and video matrix to form a second transmission path.
S103, switching a signal transmission path for transmitting the audio and video signals from the first transmission path to the second transmission path so as to continue the video conference through the standby terminal.
If the server monitors that the main terminal has a fault through the conference management software, the server can control the audio/video interface of the standby terminal to be connected with the audio/video signal input/output device through the audio/video matrix to form a second transmission path, so that the signal transmission path for transmitting the audio/video signals is switched from the first transmission path to the second transmission path, the video conference is continued through the standby terminal, and the target meeting-participating site can be ensured to be normally opened in the video conference.
By the method, when the terminal accessed to the video conference breaks down, the main equipment and the standby equipment can be switched seamlessly, so that the situation that the participating meeting places quit the video conference due to the fact that the terminal breaks down is avoided, and the conference accident is avoided. Moreover, due to the seamless switching, the participants can not feel the interruption of the picture and the sound, and the video conference experience is improved.
In a possible implementation manner, whether the main terminal is reachable on the network or not can be monitored in the monitoring process, or whether a signal is input or output at an audio/video interface of the main terminal is monitored, so that the manner of monitoring the fault of the main terminal can include monitoring that the main terminal is not reachable on the network; or, no signal input or output of the audio/video interface of the main terminal is monitored.
In a possible implementation manner, the monitoring of whether there is a signal input or output of the audio/video interface of the primary terminal may be obtained from a Software Development Kit (SDK), and the monitoring of whether there is a signal input or output of the audio/video interface of the primary terminal may be obtained from the Software Development Kit of the primary terminal, so as to determine that there is no signal input or output of the audio/video interface of the primary terminal according to the input/output parameter information. In general, if the corresponding input parameter in the input/output parameter information is null, it indicates that the audio/video interface of the master terminal has no signal input, and if the corresponding output parameter in the input/output parameter information is null, it indicates that the audio/video interface of the master terminal has no signal output.
By the method, whether the audio/video interface of the main terminal has signal input or output can be determined quickly and accurately, switching efficiency is improved, and meeting participation experience is prevented from being influenced.
In a possible implementation mode, the audio/video matrix is specially used for switching and distributing audio/video signals, multiple paths of audio/video signals can be switched and transmitted to any one of the output paths from the input paths, and the output paths are independent of each other. Based on the characteristics of the audio/video matrix, the audio/video interface of the standby terminal is controlled to be connected with the audio/video signal input/output equipment, and the second transmission path is formed by sending a control instruction to the audio/video matrix and responding to the control instruction through the audio/video matrix to control the audio/video interface of the standby terminal to be connected with the audio/video signal input/output equipment.
The audio and video interfaces of the main terminal and the standby terminal are respectively connected with the audio and video signal input and output equipment of the target meeting place through physical lines, after the fault of the main terminal is monitored, the audio and video matrix is controlled to connect the audio and video interface of the standby terminal with the audio and video signal input and output equipment to form a second transmission path, the switching from the first transmission path to the second transmission path is completed, and then the switching from the main terminal to the standby terminal is completed, so that manual operation is not needed, and the flexibility and the convenience of audio and video switching are improved. Meanwhile, the participants can not feel the interruption of the picture and the sound, and the video conference experience is improved.
It should be noted that, after the terminal participating in the video conference is switched from the main terminal to the standby terminal, the monitoring object of the conference management software may also be changed, that is, during the video conference through the standby terminal, the standby terminal is monitored, so that the monitoring object is changed from the original main terminal to the standby terminal, so as to continuously monitor whether the standby terminal fails.
It can be understood that after it is determined that the active terminal fails and the terminal participating in the video conference is switched from the active terminal to the standby terminal, the active terminal can be troubleshot. In some cases, the failure of the main terminal may be caused by network conditions, access addresses, and the like, and a conference administrator may perform online troubleshooting without disturbing the progress of the video conference.
In other cases, the failure of the main terminal may be caused by hardware of the main terminal or a connection problem of the main terminal in the target meeting place, and in such cases, in order to avoid disturbing the normal operation of the video conference, a conference manager may enter the target meeting place to perform troubleshooting after the video conference in the target meeting place is finished.
And when the fault is cleared, the main terminal is controlled to be recovered to be on-line after the fault is repaired by the main terminal. By timely restoring the main terminal to be on-line, the main terminal and the standby terminal in the target meeting place can be ensured to be on-line simultaneously as much as possible to prevent the standby terminal from being in failure, so that the available main terminal can be switched when the standby terminal is in failure.
If the main terminal finishes fault repair and is on-line in the process of the video conference, if the standby terminal is monitored to have a fault in the subsequent process of the video conference, the audio and video interface of the main terminal is controlled to be connected with the audio and video signal input and output equipment, the audio and video signal input and output equipment can be controlled to be connected after the switching is repeated, and the monitored object is changed into the main terminal.
If the main terminal finishes fault repair and is on-line after the video conference is finished, if other video conferences are carried out in the target meeting place, if the standby terminal is monitored to have faults in the process of carrying out other video conferences, the audio and video interface of the main terminal is controlled to be connected with the audio and video signal input and output equipment, the switching is repeated, and the monitored object is changed into the main terminal.
According to the technical scheme, the embodiment of the application has the following advantages:
the embodiment of the application provides an audio and video signal switching method, when a video conference is carried out, a main terminal and a standby terminal are deployed in each meeting place (taking a target meeting place as an example) participating in the video conference, and audio and video interfaces of the main terminal and the standby terminal are respectively connected with audio and video signal input and output equipment of the target meeting place through an audio and video matrix in a physical circuit mode.

And monitoring the main terminal to monitor whether the main terminal has a fault or not in the process of carrying out the video conference through the main terminal. If the main terminal is monitored to be in fault, an audio and video interface of the standby terminal is controlled to be communicated with the audio and video signal input and output equipment through the audio and video matrix to form a second transmission path, and the signal transmission path for transmitting the audio and video signals is switched from the first transmission path to the second transmission path so as to continue the video conference through the standby terminal and ensure that the video conference is normally carried out.
