[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] In existing technologies, upgrading a server requires stopping the current business operations and then using update software to update the program to complete the software system upgrade. This update method not only disrupts the current server environment but also affects the user experience even if business recovery is possible after the upgrade. Furthermore, restarting the system takes a significant amount of time, thus impacting both server upgrade efficiency and user experience. Based on this, this application proposes the following technical solution, as detailed below:

[0046] In one embodiment, such as Figure 1 As shown, Figure 1 This is a flowchart illustrating a hot-upgrade method for a display server provided in an embodiment of this application; this application provides a hot-upgrade method for a display server, the method including:

[0047] S110: When a new display server is detected to be starting up, the streaming server is instructed to push the stream to both the old and new display servers simultaneously, and the old display server is instructed to continue displaying the display screen corresponding to the stream, while the new display server does not display the display screen corresponding to the stream.

[0048] In this step, when a hot upgrade of the old display server is required, this application can pre-install and debug the new display server, and monitor the startup status of the new display server in real time. At this time, the streaming server will normally push the bitstream to the old display server according to the bitstream push request from the old display server. When the startup of the new display server is detected, the streaming server can be instructed to push the bitstream to both the old and new display servers simultaneously, and instruct the old display server to continue displaying the display screen corresponding to the bitstream, while the new display server only accepts the bitstream but does not display the display screen corresponding to the bitstream.

[0049] In this application, the new display server refers to the server with display function after the function upgrade, while the old display server refers to the server with display function before the function upgrade. Both servers have display function, but the new display server is superior to the old display server in terms of overall compatibility and functional diversity.

[0050] S120: Calculate the exchange time between the new display server and the old display server based on the startup time of the new display server, and when the exchange time arrives, instruct the new display server and the old display server to perform display exchange according to the pre-agreed exchange method.

[0051] In this step, the streaming server is instructed via S110 to simultaneously push the bitstream to both the old and new display servers. The old display server is instructed to continue displaying the corresponding screen of the bitstream. After the new display server stops displaying the corresponding screen of the bitstream, this application can calculate the exchange time between the new and old display servers based on the startup time of the new display server. When the exchange time arrives, the new and old display servers are instructed to perform display exchange according to the pre-agreed exchange method. This allows for hot server upgrades without the user's notice, without affecting the environmental status of the old display server, and without requiring a restart operation, thus saving a significant amount of upgrade time while improving the user experience.

[0052] As we can understand, hot upgrade refers to upgrading functionality by adding, modifying, or deleting relevant functional modules without stopping the program / service. Currently, the hot upgrade function of the distributed splicing processor maintains video playback and completes the software system upgrade during the upgrade process. The advantage of this function is that it can maintain smooth video playback during the upgrade process, which can provide a better user experience in some business scenarios, especially those with high real-time requirements, and it does not require a system restart.

[0053] In one specific implementation, such as Figure 2 As shown, Figure 2 A flowchart illustrating the process architecture between the streaming server, the new display server, and the old display server provided in this embodiment of the application. Figure 2 Before the new display server is detected to be starting up, the streaming server only transmits the bitstream to the old display server. When the new display server starts up, the streaming server transmits the bitstream not only to the old display server but also to the new display server. During this process, the streaming server tells the old display server the stop display time and tells the new display server the display time. When the old display server reaches the stop display time, it will stop displaying the display screen corresponding to the bitstream and exit the program, and only display the received bitstream through the new display server.

[0054] In the above embodiments, when the startup of a new display server is detected, the streaming server can be instructed to push the stream to both the old and new display servers simultaneously. The old display server is instructed to continue displaying the corresponding display screen of the stream, while the new display server does not display the corresponding display screen after receiving the stream. Next, this application can calculate the exchange time between the new and old display servers based on the startup time of the new display server. When the exchange time arrives, the new and old display servers are instructed to perform a display exchange according to a pre-agreed exchange method. This avoids affecting the environmental state of the old display server and eliminates the need to spend a significant amount of time restarting the system, thereby effectively improving server upgrade efficiency and enhancing the user experience.

[0055] In one embodiment, calculating the exchange time between the new display server and the old display server based on the startup time of the new display server in step S120 may include:

[0056] S121: Monitor and record the startup time of the new display server through the streaming server.

[0057] S122: Calculate the exchange time between the new display server and the old display server corresponding to the startup time using a preset exchange time calculation strategy.

[0058] In this embodiment, when calculating the exchange time between the new and old display servers, this application can monitor and record the startup time of the new display server through a streaming server, and calculate the exchange time between the new and old display servers according to a preset exchange time calculation strategy.

[0059] For example, once the startup time T1 of the new display server is determined, the time T1+N can be used as the exchange time between the old and new servers. N can be set according to the actual situation, such as according to the transmission rate of the bitstream, or according to the degree of difference between the old and new display servers, or according to the working status of the streaming server. These will not be elaborated here.

[0060] In one embodiment, before instructing the new display server and the old display server to perform a display exchange according to a pre-agreed exchange method when the exchange time arrives in step S120, the following may also be included:

[0061] S210: Obtain the timestamp corresponding to the data frame to be pushed in the bitstream pushed by the push server in real time.

[0062] S220: Compare the timestamp corresponding to the acquired data frame with the exchange time, and obtain the comparison result.

[0063] S230: When the comparison result meets the preset marking conditions, the acquired data frame is marked to obtain a marked frame.

[0064] In this embodiment, after determining the exchange time of the old and new display servers, this application can also obtain the timestamp corresponding to the data frame to be pushed in the bitstream pushed by the push server in real time, and compare the timestamp corresponding to the data frame obtained in real time with the exchange time. If the comparison result meets the preset marking conditions, the corresponding data frame is marked and a marked frame is obtained. The marked frame can be used to inform the old and new display servers of the exchange time.

[0065] Specifically, since the stream pushed by the streaming server is composed of data frames, once the exchange time is determined, the timestamp corresponding to the data frame to be pushed by the streaming server can be continuously monitored and compared with the exchange time. When it is the same as or close to the exchange time, it can be regarded as the data frame meeting the marking condition. At this time, the data frame can be marked to obtain the marked frame.

[0066] In one embodiment, the arrival of the exchange time includes when the new display server and the old display server receive the marker frame pushed by the streaming server; S120, instructing the new display server and the old display server to perform display exchange according to a pre-agreed exchange method when the exchange time arrives, may include:

[0067] S123: Instruct the old display server to stop displaying the display screen corresponding to the marker frame and exit the service when it receives the marker frame pushed by the streaming server.

[0068] S124: Instruct the new display server to start displaying the display screen corresponding to the marker frame when it receives the marker frame pushed by the streaming server.

[0069] In this embodiment, when the exchange time of this application arrives, it indicates that the new display server and the old display server have received the marker frame pushed by the streaming server. At this time, the distributed splicing processor can instruct the old display server to stop displaying the display screen corresponding to the marker frame and exit the service when it receives the marker frame sent by the streaming server, and instruct the new display server to start displaying the display screen corresponding to the marker frame when it receives the marker frame pushed by the streaming server.

[0070] Indicatively, such as Figure 3 As shown, Figure 3 A diagram illustrating the timeline of the exchange between old and new display servers provided in this embodiment of the application; Figure 3In the process of the old display server receiving the bitstream sent by the push server, if the distributed splicing processor detects the startup of the new display server, it can instruct the push server to simultaneously push the bitstream to both the old and new display servers. However, at this time, only the old display server displays the bitstream; the new display server receives the bitstream but does not display it. Figure 3 The content of the fourth, fifth, and sixth frames in the video. During this process, the distributed splicing processor can mark the data frames to be pushed on the streaming server according to the exchange time between the old and new servers. When both the old and new display servers receive the marked frames, such as... Figure 3 The new display server starts displaying the seventh frame, followed by the eighth, ninth, and so on. The old display server stops displaying after receiving the seventh frame and exits the service, thus completing the server exchange.

[0071] The following describes the hot-upgrade device for the display server provided in the embodiments of this application. The hot-upgrade device for the display server described below can be referred to in correspondence with the hot-upgrade method for the display server described above.

[0074] The hot-upgrade module 220 is used to calculate the exchange time between the new display server and the old display server based on the startup time of the new display server, and when the exchange time arrives, instruct the new display server and the old display server to perform display exchange according to a pre-agreed exchange method.

Next, this application can calculate the exchange time between the new and old display servers based on the startup time of the new display server. When the exchange time arrives, the new and old display servers are instructed to perform a display exchange according to a pre-agreed exchange method.
