and step S206, switching the MCU from the first line to a second line, and communicating with all conference equipment of the telepresence conference place through the second line, wherein the first line and the second line follow different communication protocols.
In the prior art, when a communication line of a certain seat of a certain telepresence meeting place has a fault, conference equipment related to the fault is often switched to a standby line, and after the switching, a plurality of seat conference terminals in the same telepresence meeting place can communicate with an MCU through different types of lines, for example, one part of seats in the telepresence meeting place communicate with the MCU through an E1 line, and the other part of seats communicate with the MCU through an IP line, so that the control logic of the MCU to the same telepresence meeting place is complex, and the communication strategy cannot be unified.
According to the method provided by the embodiment, when the MCU detects that a communication line (a first type line) of a certain telepresence meeting place has a fault, for example, the communication line of at least one seat conference terminal has a fault, other conference terminals of the meeting place are informed to disconnect the current data line, all conference equipment of the meeting place are called by a standby line (a second type line), and the line switching of all equipment in the meeting place is realized, so that all conference terminals of the same meeting place communicate with the MCU through the same line, the control complexity of MCU communication is reduced, the control logic is simplified, and the processing efficiency is improved.
In the implementation process, the first line and the second line are based on different communication protocols, namely when control signaling and media stream data (including video stream data and audio stream data) are transmitted, the signaling or data are coded by using different communication protocols. The two types of lines or the backup line are used, and once a certain type of line fails, all the conference terminals in the conference place are switched to the backup line.
In the implementation process, optionally, the first line is an E1 line, the second line is an IP line, and when one or more E1 lines of a certain meeting place have a fault, the MCU controls all conference devices in the meeting place to switch to the IP line.
In the implementation process, optionally, the first line is an IP line, the second line is an E1 line, and when one or more E1 lines of a certain meeting place have a fault, the MCU controls all conference devices in the meeting place to switch to the IP line.
In the implementation process, optionally, no matter whether the meeting place currently uses the E1 line or the IP line, once a line fails, the meeting place can be switched to another line, and the MCU can also control the meeting place to switch from the backup line back to the previous line, i.e. cyclic switching of the two types of lines is implemented.
Preferably, the detecting, by the MCU, that the first type line is faulty includes: the MCU detects that a first type line between the MCU and one conference device of the telepresence conference room has a fault.
In the implementation process, the most common communication line fault is that a communication line of one conference device in a conference place has a fault, and once the MCU detects that a first type line of a certain telepresence conference place has a fault, the MCU triggers the line switching of the telepresence conference place.
Preferably, the switching of the MCU from the first type line to the second type line comprises:
step S2062, the MCU disconnects the first type of lines between the conference equipment except the conference equipment related to the fault in the telepresence conference place;
in step S2064, the MCU calls all the conference devices through the second type of line to invite all the conference devices to join the conference through the second type of line.
Through the steps S2062 to S2064, the whole circuit switching of all the conference equipment of the telepresence meeting place is realized, so that the telepresence meeting place after switching is ensured to be communicated with the MCU through the second type of circuit, the control logic complexity of the MCU to the meeting place is reduced, and the processing efficiency of the MCU is improved.
Preferably, when the MCU detects that the first type line between the MCU and one of the conference devices in the telepresence meeting place is faulty, the method may further include: the conference equipment related to the fault detects the fault; the conference device associated with the failure maintains the local media playback.
In the implementation process, each conference terminal has a line fault detection function like an MCU, once a line in a conference room has a fault, the MCU detects the fault, and the conference terminal communicating with the MCU through the line also detects the fault of the line, and in a short time thereafter, the MCU completes the line switching of the conference room, and during the period of switching, in order to avoid interruption (e.g., sound loss or image loss) of media playing of the conference device associated with the fault, the conference device associated with the fault keeps local media playing, e.g., media data of a period of time before playing, thereby achieving higher user experience.
Preferably, before the MCU disconnects the first type line with other conference devices, the method may further comprise: and informing other conference devices to respectively keep local media playing.
In the implementation process, once a certain line in a conference room has a fault, the MCU detects the fault, and in a short time thereafter, the MCU completes the line switching of all conference devices in the conference room, during the switching time, in order to avoid interruption (for example, sound missing or image missing) of media playing of other conference devices unrelated to the fault in the conference room, the MCU sends a message (which may be, but is not limited to, an existing message or a non-standard message) to the other conference devices to notify the other conference devices to respectively keep local media playing, and after receiving the message, the other conference devices keep local media playing, for example, media data in a period before playing, thereby achieving higher user experience.
Preferably, before the MCU calls all conference devices through the second type line, the method may further comprise: recording the playing setting of each telepresence meeting place communicated with the MCU, wherein the playing setting comprises the corresponding relation between each telepresence meeting place and the media stream played by each telepresence meeting place.
After all the conference devices join the conference through the second type line, the method may further include: and controlling each telepresence meeting place to play the corresponding media stream according to the playing setting.
In the specific implementation process, before implementing line switching, the MCU records the play settings of each meeting place, including: recording the playback settings of the broadcaster's venue (the master venue), and playing back the playback devices of the other venues of the broadcaster's venue locally. The above play setting includes: the corresponding relationship between each telepresence meeting place and the media stream played by the telepresence meeting place, for example, which seat of which meeting place is played by each screen of each meeting place. After the circuit switching is completed, the MCU controls each telepresence meeting place to respectively play the corresponding media streams according to the playing setting.
By the preferable method, the playing effect of each meeting place after switching is ensured to be the same as that before switching, so that a user does not feel that the system fails, and higher user experience is realized.

In combination with the real network site networking mode shown in fig. 1, the procedure of switching from the E1 line to the IP line includes:
step S302, the MCU detects the E1 private line state between the telepresence meeting place 1 (seat 1, seat 2 and seat 3) and the MCU in real time.
Step S304, when the MCU finds that the E1 line between the seat 2 of the telepresence meeting place 1 and the MCU is in fault, the MCU judges whether the IP line between the current MCU and the telepresence meeting place 1 is normal or not, if all the IP lines are normal, the switching process is started, and if not all the IP lines are normal, the switching process is ended.
Step S306, after finding out the E1 private line fault between the agent 2 and the MCU, the agent continues to keep playing the media.
Step S308, the MCU judges whether the telepresence meeting place 1 is a non-single-screen meeting place, if so, firstly, the MCU sends media non-standard keeping information to the seat 1 and the seat 3, and the seat 1 and the seat 3 still keep playing the media after receiving the non-standard information and after a signaling end between the MCU is opened. The MCU then disconnects the E1 lines for seat 1 and seat 3.
Step S310, the MCU records the playing setting of each telepresence meeting place;
step S312, the MCU calls the telepresence meeting place 1 in an IP mode, and after the telepresence meeting place 1 joins the conference in an IP circuit, the MCU controls each telepresence meeting place to play the corresponding media stream according to the recorded playing setting.

step S402, the MCU detects the IP circuit state between the telepresence meeting place 1 (seat 1, seat 2 and seat 3) and the MCU in real time, and the method comprises two types of media detection and signaling detection. The signaling detection means that the real meeting place/seat of the network does not respond to the roundtrip delay message of the MCU within a certain time (can be configured by self), and the MCU considers that the IP line has a fault; the media detection means that the MCU media receiving module does not receive the media sent by the telepresence meeting place/seat within a certain time (can be configured by itself), and the MCU considers that the IP line is faulty.
Step S404, when the MCU finds that the IP circuit between the seat 2 of the telepresence meeting place 1 and the MCU is in fault, the MCU judges whether the E1 circuit between the MCU and the telepresence meeting place 1 is normal, if all is normal, the backup process is started, and if not, the backup process is ended.
Step S406, after the agent 2 finds the IP network fault between the agent 2 and the MCU (the method for judging the IP line fault between the agent 2 and the MCU can be based on the judgment principle of the MCU), the playing of the media is continuously kept.
Step S408, the MCU judges whether the telepresence meeting place 1 is a non-single-screen telepresence meeting place, if so, the MCU firstly sends media non-standard keeping messages to the seat 1 and the seat 3, and after the seat 1 and the seat 3 receive the non-standard messages, the playing of the media is still kept within a certain time (can be configured by themselves) even if a signaling end between the seat 1 and the MCU is opened. Then, the MCU disconnects seat 1 and seat 3, and the telepresence meeting place 1 is completely disconnected from the MCU in an IP manner.
And step S410, the MCU records the play setting of each telepresence meeting place.
And step S412, the MCU calls the telepresence meeting place 1 in an E1 mode, and after the telepresence meeting place 1 joins the conference in an E1 circuit, the MCU controls each telepresence meeting place to play the corresponding media stream according to the recorded playing setting.
