The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The Server switching method provided by the embodiment of the invention can be suitable for the situation of dynamically switching servers in an audio and video interaction scene, the client corresponding to the live broadcast room is triggered to monitor the video stream quality data through the synchronous detection signal, so that the client can determine the network quality value according to the monitored video stream quality data, the switching value of the Streaming Media Server (Streaming Media Server) currently connected to the live broadcast room can be determined according to the network quality value determined by each client, and when the switching value of the Streaming Media Server currently connected to the live broadcast room is lower than the preset switching threshold value, the Streaming Media Server currently connected to the live broadcast room is switched to the backup Streaming Media Server, so that the video stream data generated in the live broadcast room is transmitted through the backup Streaming Media Server.
It should be noted that the video stream data in the embodiment of the present invention may refer to various data generated in a representation live broadcast room, and specifically may include video data, audio data, text data, and the like generated in the live broadcast room, where the video data may be used to represent video played in the live broadcast room, the audio data may be used to represent audio played in the live broadcast room, and the text data may be used to represent text displayed in the live broadcast room.
The live broadcast room in the embodiment of the invention can be a virtual room created in an audio and video interaction scene. The user may enter the virtual room through the client to perform audio and video interaction with other users in the virtual room, for example, share the audio and video sent by the user with other users in the same virtual room, obtain the audio and video sent by other users in the same virtual room, and the like.
In actual processing, an audio/video interactive system can be formed by a client, a room management server and a streaming media server provided by one or more third-party audio/video service providers. As shown in fig. 1, a user a, a user B, and a user C may respectively join a virtual room through clients installed in different devices, and the devices used by the three users may establish long connections with a room management server through the clients, so that the devices or clients used by each user in the virtual room may pull audio and video streams sent by other clients in the same virtual room.

The streaming media server can be mainly used for providing video push-pull streaming service, that is, when all users in the same virtual room use the audio/video streaming service provided by the same audio/video manufacturer, the streaming media server provided by the audio/video manufacturer can be used for transmitting audio/video streams, so that remote real-time audio/video interaction is realized.
Referring to fig. 2, a flowchart illustrating steps of a server switching method in the embodiment of the present invention is shown, which may specifically include the following steps:
step 210, in the process of generating video stream data in a live broadcast room, sending a synchronous detection signal to a client corresponding to the live broadcast room to trigger the client to monitor video stream quality data.
Specifically, a user can log in a room management server of the audio and video interaction system through a client so as to enter a live broadcast room to perform remote real-time audio and video interaction with other users. When a user performs audio-video interaction with other users, the live broadcast room can generate corresponding video stream data, and the generated video stream data can be distributed to a client corresponding to the live broadcast room through a stream media server (namely an initial stream media server) currently connected with the live broadcast room, so that each user added to the live broadcast room can acquire the video stream data generated in the live broadcast room. The client corresponding to the live broadcast room may refer to a client used by a user who joins in the live broadcast room, the client may be implemented in a software and/or hardware manner, may be formed by two or more physical entities, may also be formed by one physical entity, and the like, and the implementation of the present invention is not limited thereto.
In the embodiment of the invention, in the process of generating video stream data in the live broadcast room, a synchronous detection signal can be sent to each client corresponding to the live broadcast room, so that each client in the live broadcast room is triggered to monitor the video stream quality data through the synchronous detection signal, each client can determine the current network quality value based on the monitored video stream quality data, and whether a streaming media server connected with the live broadcast room needs to be switched can be determined based on the network quality value determined by each client.
In the specific implementation, when a certain client generates a synchronous detection signal corresponding to a live broadcast room, the client can be used as a target client, and the synchronous detection signal can be sent to the client corresponding to the live broadcast room through the target client, so that each client in the same live broadcast room as the target client can receive the synchronous detection signal, each client in the same live broadcast room is triggered to synchronously monitor video stream quality data through the synchronous detection signal, and each client can determine a network quality value according to the monitored video stream quality data.
It should be noted that the synchronization detection signal in the embodiment of the present invention may be generated by an objective end in an audio/video system, and preferably, may be generated by a client having a management authority in the live broadcast room, and the like, which is not specifically limited in this embodiment of the present invention. The video stream quality data may include various data representing video quality, such as delay data, packet loss rate data, audio/video code rate data, video frame rate data, and/or pause rate data, which is not limited in this embodiment of the present invention. The Time delay data can be used for representing the Time delay of video stream data transmission, such as Round-Trip Time (RRT) and the like, the packet loss rate data can be used for representing the packet loss rate of video stream data transmission, the audio and video code rate data can include audio code rate data and/or video code rate data, the audio code rate data can be used for representing an audio code rate, the video code rate data can be used for representing a video code rate, and the pause rate data can include audio pause rate, video pause rate and the like.
Step 220, determining a switching value of the initial streaming media server according to the first network quality value fed back by the client and the locally determined second network quality value.
The first network quality value is determined by the client according to the monitored video stream quality data, the second network quality value is determined locally according to the monitored video stream quality data, and the initial streaming media server is a streaming media server connected with the live broadcast room.
In the embodiment of the invention, after each client corresponding to the live broadcast room receives the synchronous detection signal, the video stream quality data can be monitored according to the synchronous detection signal, then comprehensive calculation can be carried out according to the monitored video quality data to obtain a comprehensive score, and the comprehensive score can be used as a first network quality value to feed back the target client sending the synchronous detection signal for summarizing. In addition, after the target client generates the synchronous detection signal corresponding to the live broadcast room, the target client can start to monitor the local video stream quality data based on the synchronous detection signal, so that comprehensive calculation can be performed based on the locally monitored video stream quality data to obtain a comprehensive score serving as a second network quality value. The first network quality value determined by the client may be used to characterize the link quality between the client and the initial streaming media server currently connected to the live broadcast room, and if the first network quality value is lower, the link quality between the client and the initial streaming media server may be characterized to be worse. Similarly, the second network quality value determined by the target client may be used to characterize the link quality between the target client and the initial streaming server, e.g., the lower the second network quality value, the worse the link quality between the client and the initial streaming server may be characterized.
In a specific implementation, after the target client determines the local second network quality value, a summary process may be performed based on the second network quality value and the first network quality values fed back by the clients, so as to determine a switching value of the initial streaming media server currently connected to the live broadcast room. The switching value of the initial streaming media server can be used to determine whether the initial streaming media server needs to be switched, that is, whether the live broadcast room needs to be switched from the initial streaming media server to the backup streaming media server, so as to transmit the video stream data generated in the live broadcast room through the backup streaming media server. If the switching value of the initial streaming media server exceeds the preset switching threshold value, it can be determined that the video push-pull streaming services provided by the initial streaming media server for each client in the live broadcast room are relatively good, and each client in the live broadcast room does not need to be switched to other streaming media servers from the initial streaming media server, so that the overhead caused by switching of the streaming media servers is avoided, and the real-time performance of video streaming data transmission in the live broadcast room is ensured. If the switching value of the initial streaming media server is lower than the preset switching threshold, it may be determined that the video push-pull streaming service provided by the initial streaming media server for each client in the live broadcast room is relatively poor, that is, it may be determined that the link quality between the initial streaming media server and each client in the live broadcast room is relatively poor, and then step 230 is executed. The preset switching threshold may be used to determine whether a streaming media server needs to be switched, and specifically may be set according to a transmission requirement of video stream data in a live broadcast room, for example, may be set according to transmission quality and/or transmission real-time performance of the video stream data in the live broadcast room, which is not limited in this embodiment of the present invention.
Step 230, when the switching value is lower than a preset switching threshold value, switching the live broadcast room from the initial streaming media server to a backup streaming media server, and sending a switching message corresponding to the live broadcast room to the client, where the switching message is used to trigger the client to switch to the backup streaming media server.
In the embodiment of the invention, when the target client determines that the switching value of the initial streaming media server currently connected with the live broadcast room is lower than the preset switching threshold value, the target client can switch the live broadcast room from the currently connected streaming media server to the backup streaming media device, simultaneously can generate the switching message corresponding to the live broadcast room, and can send the switching message corresponding to the live broadcast room to each client corresponding to the live broadcast room so as to trigger each client to switch to the backup streaming media server, so that each client added to the live broadcast room can be synchronously switched to the backup streaming media server, the dynamic switching of the streaming media server in the remote real-time audio and video interaction process is realized, the problem that the interaction real-time performance of the existing audio and video interaction application software depends on the streaming media server provided by a third party audio and video service provider is limited is solved, and the real-time performance of audio and video stream transmission generated in the live broadcast room is, the interactivity of the user in the audio and video interaction process is improved, and the user experience is improved.
In the actual processing, a user can log in by using a client side and can join in a live broadcast room through the client side to perform remote audio and video interaction with other users. Therefore, the embodiment of the invention can determine whether the client used by the login user can distribute the synchronous detection signal corresponding to the live broadcast room by detecting whether the login user has the management authority of the live broadcast room, so as to trigger the client corresponding to the live broadcast room to synchronously detect the video quality data. Optionally, before sending the synchronization detection signal to the client corresponding to the live broadcast room, the server switching method in this embodiment may further include: determining a login user according to the login information; and if the login user has the management authority of the live broadcast room, generating a synchronous detection signal corresponding to the live broadcast room according to the management authority.
Specifically, when a user logs in by using the client, the client can determine a current login user according to login information of the user, for example, the login user can be determined according to a login account or a login user name input by the user, a live broadcast room into which the user enters can be determined according to the login information and/or user operation input by the user, whether the login user has a management authority of the live broadcast room can be determined, and whether the login user has the management authority of the live broadcast room can be determined by using the room management server. If the login user has the management authority of the live broadcast room, the client used by the login user can be used as a target client in the live broadcast room, a synchronous detection signal corresponding to the live broadcast room is generated according to the management authority of the user, the synchronous detection signal can be sent to the client used by each user added to the live broadcast room, the synchronous detection signal is sent to each client corresponding to the live broadcast room, and each client is enabled to monitor video quality data respectively according to the synchronous detection signal; meanwhile, the target client can detect the video stream quality data prepared locally according to the currently generated synchronous detection signal so as to determine the second network quality value according to the locally detected video stream quality data.
Further, the client in the embodiment of the present invention may locally store the currently stored data before monitoring the video quality data, for example, clear local historical video stream quality data, so as to save the local storage space, avoid the influence of the historical video stream quality data on the currently monitored video stream quality data, and ensure the monitoring accuracy. The historical video stream quality data may refer to video stream quality data historically monitored by the client, such as time delay data, packet loss rate data, audio/video code rate data, video frame rate data and/or pause rate data, which are monitored by the client before and stored in the local.
In an optional embodiment of the present invention, the server switching method may further include: clearing local historical video stream quality data according to the synchronous detection signal; monitoring local video stream quality data; and determining a second network quality value corresponding to the initial streaming media server according to the local video stream quality data. Specifically, after generating a synchronization detection signal corresponding to a live broadcast room, a target client in the embodiment of the present invention may locally store historical video stream quality data based on a synchronization detection signal condition, and then may monitor video stream quality data corresponding to the live broadcast room, so as to determine, by using the currently monitored video stream quality data, a second network quality value corresponding to a network corresponding to an initial streaming media server currently connected to the live broadcast room. Optionally, the monitoring of the local video stream quality data specifically includes: monitoring video stream data transmitted by the initial streaming media server to obtain local video stream quality data, wherein the video stream quality data comprises at least one of the following data: time delay data, packet loss rate data, audio and video code rate data, video frame rate data and pause rate data. It should be noted that the video stream data transmitted by the initial streaming media server may refer to video stream data transmitted by the initial streaming media server, and specifically may include video stream data that is sent by the target client to other clients in the live broadcast room through the initial streaming media server, and may also include video stream data that is sent by the target client to other clients in the live broadcast room through the initial streaming media server.
In a specific implementation, after the target client clears the local historical video stream quality data, the target client may monitor video stream data transmitted by an initial streaming media server currently connected to the live broadcast room within a preset period of time, and may determine local video stream quality data based on the video stream data monitored within the period of time, so as to perform comprehensive calculation by using the locally determined video stream quality data to obtain a second network quality value. Then, the target client may perform a trade-off process by using the second network quality value and the first network quality value fed back by each client in the same live broadcast room, so as to determine a switching value of the initial streaming media server currently connected to the live broadcast room.
In an optional embodiment of the present invention, determining the switching value of the initial streaming media server according to the first network quality value fed back by the client and the locally determined second network quality value may specifically include: receiving a first network quality value fed back by at least one client; and respectively comparing the second network quality value and the first network quality value fed back by each client with a preset quality threshold, and determining the switching value of the initial streaming media server based on the comparison result.
Specifically, after the target client sends the synchronization detection signal to the client corresponding to the live broadcast room, each client receiving the synchronization detection signal may be triggered to determine a corresponding first network quality value according to the video stream quality data monitored by each client, and each client may feed back the determined first network quality value to the target client, so that the target client may receive the first network quality value fed back by each client. The target client may compare the received first network quality value and the locally determined second network quality value with a preset quality threshold, respectively, so as to determine the switching value of the initial streaming media server by using a comparison result obtained by the comparison. The comparison result can be used for comprehensively measuring the link quality between the initial streaming media server and each client of the live broadcast room. If the link quality between the initial streaming media server and each client of the live broadcast room is good, the switching value of the initial streaming media server determined based on the comparison result may be higher than a preset switching threshold. If the link quality between the initial streaming media server and each client of the live broadcast room is poor, the switching value of the initial streaming media server determined based on the comparison result may be lower than a preset switching threshold.
It should be noted that the preset quality threshold may refer to a quality value corresponding to the minimum network condition that can be accepted by the live broadcast room, and may be specifically set according to the audio/video quality of the video stream data generated in the live broadcast room after being transmitted through the streaming media server under different network conditions, which is not specifically limited in this embodiment of the present invention. For example, under various network conditions simulated in advance, video stream quality data such as packet loss data, delay data, audio/video code rate and the like corresponding to video stream data generated in a live broadcast room after being transmitted through a streaming media server under different network conditions are collected, then the audio/video quality of the video stream data transmitted through the streaming media server can be determined according to the video stream quality data, then the network quality value corresponding to the minimum network condition acceptable in the live broadcast room can be determined based on the transmitted audio/video quality, and the network quality value corresponding to the minimum network condition can be used as a preset quality threshold.
In this embodiment of the present invention, optionally, the comparing the second network quality value and the first network quality value fed back by each client with a preset quality threshold, and determining the switching value of the initial streaming media server based on the comparison result respectively includes: comparing the second network quality value and the first network quality value fed back by each client with a preset quality threshold respectively, and determining the number of clients to be switched as a comparison result, wherein the number of the clients to be switched is the number of the clients corresponding to the condition that the network quality value in the live broadcast room is lower than the preset quality threshold, and the network quality comprises the first network quality value and the second network quality value; and determining the switching value of the initial streaming media server based on the number of the clients to be switched. Specifically, the target client may compare the second network quality value determined locally and the first network quality value fed back by each client with a preset quality threshold, to determine the client corresponding to the client whose network quality value is lower than the preset quality threshold in the live broadcast room to which the target client is added, and may count the number of clients whose network quality value is lower than the preset quality threshold, to obtain the number of clients to be switched, and then may determine the switching value of the initial streaming media server currently connected to the live broadcast room based on the number of clients to be switched. If the number of the clients to be switched is large, the determined switching value of the initial streaming media server can be low. For example, when the number of clients to be switched exceeds half of the number of clients in the live broadcast room, the determined switching value may be lower than a preset switching threshold value to trigger the streaming media server in the live broadcast room to switch connection, that is, to trigger the target client and other clients in the live broadcast room to switch the live broadcast room from the initial streaming media server in the current connection to the backup streaming media server, so that video stream data generated in the live broadcast room may be transmitted through the backup streaming media server connected after switching.
In actual processing, the instantaneous jitter of the network is common. In order to avoid switching of the streaming media server caused by network instant jitter, the embodiment of the invention can trigger each client in the live broadcast room to realize switching of the streaming media server when the detection times corresponding to the switching value of the initial streaming media server being lower than the preset switching threshold reach the preset detection threshold. Therefore, in an optional embodiment of the present invention, when the handover value is lower than a preset handover threshold, the method may further include: recording the detection times corresponding to the initial streaming media server; if the detection times are lower than a preset detection time threshold, updating the switching value of the initial streaming media server according to a second network quality value which is locally re-determined and a first network quality value which is fed back again by the client, and updating the detection times according to the updated switching value; and if the detection times reach a preset detection time threshold value, executing the step of switching the live broadcast room from the initial streaming media server to a backup streaming media server.
Specifically, when detecting that the switching value of the initial streaming media server is lower than the preset switching threshold, the target client in the embodiment of the present invention may record the detection times corresponding to the initial streaming media server, so that the detection times reach the preset detection times threshold, and switch the streaming media server connected to the live broadcast room from the initial streaming media server to the backup server, thereby avoiding the problem of frequent switching of the streaming media server due to network instantaneous jitter, and further reducing the additional overhead caused by frequent switching of the streaming media server.
On the basis of the foregoing embodiment, an embodiment of the present invention further provides another server switching method, which may be executed by a client in a live broadcast room, and as shown in fig. 3, the method may specifically include the following steps:
step 310, in the process of generating video stream data in the live broadcast room, receiving a synchronization detection signal sent by a target client.
In a specific implementation, after a login user joins a live broadcast room, a client may acquire video stream data generated in the live broadcast room, for example, the client may acquire video stream data sent by other users in the live broadcast room through a streaming media server connected to the live broadcast room, and may send video stream data recorded in the local by the login user to the client used by other users through the streaming media server connected to the live broadcast room. In addition, after the target client in the live broadcast room sends the synchronization detection signal, the client may also receive, through the network server, the synchronization detection signal sent by the target client in the live broadcast room, for example, the synchronization detection signal sent by the target client may be received through a room management server connected to the live broadcast room.
And step 320, monitoring video stream quality data according to the synchronous detection signal.
Specifically, after receiving the synchronization detection signal, the client in the live broadcast room may clear locally current cached data, such as historical video stream quality data currently stored locally, so as to monitor the video stream quality data after clearing the data, and ensure the monitoring accuracy.
In an optional embodiment of the present invention, the monitoring the video stream quality data according to the synchronization detection signal may specifically include: clearing local historical video stream quality data according to the synchronous detection signal; monitoring video stream data transmitted by the initial streaming media server to obtain video stream quality data, wherein the video stream quality data comprises at least one of the following data: time delay data, packet loss rate data, audio and video code rate data, video frame rate data and pause rate data.
In step 330, a first network quality value is determined based on the video stream quality data.
Specifically, after the client in the implementation of the present invention clears the local data, the client may monitor video stream data transmitted by an initial streaming media server currently connected to the live broadcast room within a preset period of time, and may determine video stream quality data based on the video stream data monitored within the period of time, so as to perform comprehensive calculation using the determined video stream quality data to obtain a first network quality value.
Step 340, feeding back the first network quality value to the target client, so as to trigger the target client to determine a switching value of the initial streaming media server according to the first network quality and the second network quality.
The second network quality is determined by the target client according to the monitored video stream quality data, and the initial streaming media server is a streaming media server connected with the live broadcast room.
For example, after the client clears the historical video stream quality data according to the received synchronization detection signal, the client may monitor the video stream data transmitted by the initial streaming media server within a preset period of time to obtain the video stream quality data within the period of time, and then may perform comprehensive calculation on the video stream quality data within the period of time to determine a first network quality value within the period of time, and then may send the first network quality value to the target client, so as to summarize the first network quality value through the target client, and determine the switching value of the initial streaming media server currently connected between live broadcasts.
Step 350, receiving a handover message corresponding to the live broadcast room, where the handover message is sent by the target client when the handover value is lower than a preset handover threshold value.
In the embodiment of the present invention, when determining that the switching value of the initial streaming media server is lower than the preset switching threshold, the target client may generate one or more corresponding switching messages for the live broadcast room, and may distribute the generated switching messages to each client corresponding to the live broadcast room, so that each client may receive the switching messages corresponding to the live broadcast room, and may trigger the client to execute step 360.
And step 360, switching the live broadcast room from the initial streaming media server to a backup streaming media server according to the switching message.
In this embodiment, optionally, before receiving the synchronization detection signal sent by the target client, the method may further include: determining a login user according to the login information; and if the login user does not have the management authority of the live broadcast room, waiting to receive a synchronous detection signal sent by a target client, wherein the target client is the client logged in by the user with the management authority.
To sum up, the embodiment of the present invention can trigger each client in the same live broadcast room to monitor the video stream quality data through the synchronous detection signal, so that the client can determine the network quality value according to the monitored video stream quality data, determine the switching value of the streaming media server currently connected to the live broadcast room according to the network quality value determined by each client, and switch the live broadcast room from the currently connected streaming media server to the backup streaming media device when the switching value of the currently connected streaming media server is lower than the preset switching threshold, so as to transmit the audio/video stream generated in the live broadcast room through the backup streaming media server, thereby implementing dynamic switching of the streaming media server, ensuring the real-time of the audio/video stream transmission generated in the live broadcast room, i.e. solving the problem that the existing audio/video interactive application software depends on the streaming media server provided by a third party audio/video service provider to cause the limited interactive real-time, therefore, the interactivity of the user in the audio and video interaction process is improved, and the user experience is improved.
For example, as shown in fig. 1, in the case that the av interactive system includes a streaming server provided by an av provider a and a streaming server provided by an av provider B, if the charging price of the audio video service provider a is cheaper than the charging price of the audio video service provider B, and under the condition of better network quality, the audio and video transmission quality of the streaming media server provided by the audio and video service provider A and the audio and video transmission quality of the streaming media server provided by the audio and video service provider B are not different greatly, the clients used by the user a, the user B and the user C which join in the same virtual room can be in communication connection with the streaming media server provided by the audio and video service provider a, and the streaming media server provided by the audio and video service provider A is adopted to transmit the video streaming data generated in the virtual room, so that the cost is saved. However, under the condition of poor network quality, if the audio/video transmission quality of the streaming media server provided by the audio/video service provider a is worse than that of the streaming media server provided by the audio/video service provider B, that is, the audio/video transmission quality of the audio/video service provider a is not as bad as that of the audio/video service provider B, in order to pursue user experience, the clients used by the user a, the user B, and the user C are all expected to be capable of dynamically switching to the streaming media server provided by the audio/video service provider B. At this time, by applying the server switching scheme provided by the embodiment of the present invention, the clients used by the user a, the user B, and the user C can dynamically switch the streaming media server provided by the audio/video service provider in the audio/video interaction process, and can ensure transparency to the outside without affecting the user operation, thereby seeking a balance between the cost and the user experience.
In actual processing, the server switching method provided by the embodiment of the invention can be applied to each client in an audio and video interactive system.
As an example of the present invention, a user may log in a room management server using any client to enter a live broadcast room through the room management server for audio and video interaction, that is, push and pull video stream data generated in the live broadcast room through an initial streaming media server connected to the live broadcast room. After the video stream data generated in the live broadcast room starts to be pushed and pulled, the client used by the user can start to continuously monitor the network condition, for example, push-pull stream quality related data can be obtained at regular time, that is, video stream quality data corresponding to the video stream data transmitted by the initial streaming media server is obtained at regular time, so as to realize regular monitoring of the network condition. Subsequently, the client can judge whether the user is an arbitrator in the live broadcast room to which the user joins according to the login information of the user, that is, whether the current login user has the management authority of the live broadcast room. The arbitrator may refer to a person who first joins the live broadcast room, such as a user who creates the direct broadcast room.
If the user is an arbitrator in the live broadcast room, the user can be determined to have the management authority, and a monitoring notification corresponding to the live broadcast room can be initiated, namely a starting signal serving as a synchronous detection signal is initiated. The signal is used for informing all clients used by users in the live broadcast room to start collecting push-pull stream quality data at the moment in the next period of time, and calculating a comprehensive score as a network quality value, namely informing each client in the direct broadcast room to collect video stream quality data in the next period of time, and determining a corresponding network quality value by using the video stream quality data collected in the period of time. For example, after a user logs in and joins a live broadcast room by using a client, if the user has the management authority of the live broadcast room, the client used by the user can be used as a target client. The target client can generate a synchronous detection signal corresponding to the live broadcast room and can send the synchronous detection signal to clients used by other users in the live broadcast room, so that each client in the live broadcast room can start to monitor video stream quality data corresponding to the live broadcast room based on the synchronous detection signal after acquiring the synchronous detection signal; meanwhile, the network quality value corresponding to the push-pull stream quality data of the user can be calculated, for example, after the current data of the user is emptied, the video stream quality data is collected and the comprehensive score is calculated to serve as the second network quality value.
If the user is not an arbitrator in the live broadcast room, the start signal initiated by the arbitrator can be waited, that is, the client logged in by the user without the management authority waits for receiving the synchronous detection signal sent by the target client. If a start signal from the arbitrator is received. Namely receiving a detection synchronization signal sent by a target client, clearing the current data of the client, starting to collect video stream quality data, calculating a comprehensive score by adopting the video stream quality data to serve as a first network quality value, and sending the first network quality value to the target client used by an arbitrator in the same live broadcast room.
After a target client used by an arbitrator receives a current network quality value calculated by other clients, namely after the target client receives a first network quality value fed back by each client corresponding to a live broadcast room, a balance can be made according to the network quality value fed back by each client in the live broadcast room to determine whether a streaming media server connected to the live broadcast room needs to be switched, namely, whether the streaming media server currently connected to the live broadcast room needs to be switched is determined according to the collected network quality value.
In the actual process, the target client or the user as the arbitrator may set a switching threshold as a preset switching threshold of the live broadcast room, and may set a number of times as a detection number threshold, for example, the detection number threshold may be set to 3 first. If the target client finds that the network quality values corresponding to the video network quality data monitored by the clients in the live broadcast room are poor in continuous monitoring for 3 times, namely the switching values of the initial streaming media servers connected to the live broadcast room are all lower than a preset switching threshold value, the clients in the live broadcast room can be informed to switch the streaming media servers connected to the live broadcast room. For example, as shown in fig. 1, when the initial streaming media server used by default in the live broadcast rooms joined by the user a, the user B, and the user C is the streaming media server provided by the audio/video service provider a, the target client used by the user B as the arbitrator detects that the switching value of the streaming media server provided by the audio/video service provider a is lower than the preset switching threshold value on the connection line for 3 times, and if the audio/video transmission quality of the audio/video service provider B is better than that of the audio/video service provider a, the streaming media server provided by the audio/video service provider B can be used as the backup streaming media server, and the client used by each user in the live broadcast room can be notified to switch the streaming media server connected to the live broadcast room to the streaming media server provided by the video service provider B, so as to avoid the problem that the video frames and/or the audio cards in the live broadcast room are played due to the poor audio/video quality transmission, the fluency of playing the video stream data generated in the live broadcast room is ensured, and the user experience is improved.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
