[0021] In order to make the purpose, technical solution and advantages of the present application more clear, the technical solution in the embodiments of the present application is further described in detail through the following embodiments and in combination with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0022] Figure 1 This is a system architecture diagram of a mobile recording and broadcasting system applicable to the wireless network-based live data transmission method provided in the embodiment of the present application. Figure 1 As shown, the mobile recording and broadcasting system may include: multiple data acquisition devices 101 and a recording and broadcasting host 102, and data communication is performed between the multiple data acquisition devices 101 and the recording and broadcasting host 102 via a wireless network. The data acquisition device 101 may include a wireless camera or a wireless microphone for collecting media data, and sending the collected media data to the recording and broadcasting host 102 via a wireless network. At the same time, multiple data acquisition devices 101 are deployed in different locations to collect media data in different areas. The recording and broadcasting host 102 encodes the media data and pushes the encoded data to the live broadcast server ( Figure 1 Optionally, the wireless network may be a wireless fidelity (WiFi) or a mobile network such as 2G / 3G / 4G / 5G / 6G, which is not limited in this embodiment.

[0023] Figure 2 A flowchart of a wireless network-based live data transmission method provided in an embodiment of the present application. The method can be executed by a wireless network-based live data transmission device, which can be implemented by software and / or hardware. In a specific embodiment, the device can be configured in the above-mentioned recording and broadcasting host. The following embodiments will be introduced by taking the device integrated in the above-mentioned recording and broadcasting host as an example. Figure 1As shown, the method may include:

[0024] S201, controlling multiple data acquisition devices to send live data frames in sequence via a wireless network.

[0025] In actual applications, in order to reduce the mutual interference of wireless signals between multiple data acquisition devices, the recording and broadcasting host can use polling scheduling to control multiple data acquisition devices to send the collected live data frames in sequence, and the data acquisition devices send live data frames in sequence according to the control instructions of the recording and broadcasting host. Figure 3 As shown, the recording and broadcasting host sequentially schedules data acquisition device 1-data acquisition device n to send the first frame. After the first frame data is scheduled, it sequentially schedules data acquisition device 1-data acquisition device n to send the second frame, and so on.

[0026] S202. When the first live data frame sent by the target data acquisition device is not successfully received, control the target data acquisition device to cache the first live data frame, and control the target data acquisition device to retransmit the first live data frame during the idle sending period of other data acquisition devices.

[0027] If the first live data frame sent by the target data acquisition device is not successfully received within the preset time, or the live data frame sent by the next scheduled data acquisition device of the target data acquisition device has been received, it can be determined that the first live data frame of the target data acquisition device is lost. In this way, the recording and broadcasting host can send a control instruction to the target data acquisition device, wherein the control instruction can carry the frame identifier of the first live data frame, which is used to instruct the target data acquisition device to cache the first live data frame corresponding to the frame identifier, and at the same time control the target data acquisition device to retransmit the first live data frame during the idle sending period of other data acquisition devices, that is, use the scheduling gap of other data acquisition devices to schedule the target acquisition device again to retransmit the lost first live data frame.

[0028] After the target data acquisition device receives the control instruction, it stores the first live data frame corresponding to the frame identifier in its own cache area according to the frame identifier carried in the control instruction, and retransmits the first live data frame during the idle sending period of other data acquisition devices. That is, when retransmitting the first live data frame, it is also necessary to avoid the scheduling time of other data acquisition devices to avoid signal interference to other data acquisition devices and cause packet loss in other data acquisition devices.

[0029] See also Figure 4, assuming that the recording and broadcasting host fails to successfully receive the live data frame 5-2 within the scheduling time of the data acquisition device 5, the recording and broadcasting host controls the data acquisition device 5 to temporarily store the live data frame 5-2 in the buffer area, and controls the data acquisition device 5 to retransmit the live data frame 5-2 before the scheduling time of other data acquisition devices arrives. For example, after the data acquisition device n sends the live data frame n-2 and before the data acquisition device 1 sends the live data frame 1-3, the data acquisition device 5 is controlled to retransmit the live data frame 5-2. If the live data frame 5-2 is still not successfully received, the data acquisition device 5 is continued to be controlled to retransmit the live data frame 5-2 within the time period after the data acquisition device 1 sends the live data frame 1-3 and before the data acquisition device 2 sends the live data frame 2-3. And so on, that is, the live data frame 5-2 is retransmitted multiple times during the idle sending time period of other data acquisition devices, so as to successfully receive the live data frame 5-2 as much as possible before the live data frame 5-3 of the data acquisition device 5 arrives, so that the live data flow of the data acquisition device 5 can be uninterrupted.

[0030] Optionally, if the recording and broadcasting host successfully receives the first live data frame, the recording and broadcasting host can control the target data acquisition device to delete the first live data frame from the buffer area to release the occupied buffer area space and reduce the memory overhead of the target data acquisition device.

[0031] The wireless network-based live data transmission method provided in the embodiment of the present application controls the target data acquisition device to cache the first live data frame sent by the target data acquisition device when the first live data frame sent by the target data acquisition device is not successfully received, and controls the target data acquisition device to timely retransmit the first live data frame during the idle sending period of other data acquisition devices, that is, utilizes the scheduling gap between the data acquisition devices to retransmit the lost first live data frame, so that the first live data frame is received as successfully as possible before the arrival of the next live data frame of the target data acquisition device, which will not cause the interruption of the live data stream, thereby solving the problem of freeze or intermittent live screen and improving the live viewing effect; and, controlling the target data acquisition device to retransmit the first live data frame during the idle sending period of other data acquisition devices can also avoid the target data acquisition device from generating signal interference to other data acquisition devices, resulting in packet loss in other data acquisition devices, further improving the live viewing effect.

[0032] In actual applications, there is also such a situation: within the current scheduling time of the target data acquisition device, the recording and broadcasting host has neither successfully received the first live data frame sent by the target data acquisition device this time, nor successfully received the second live data frame sent by the target data acquisition device before, wherein the second live data frame is the live data frame sent by the target data acquisition device before the first live data frame. For example, the recording and broadcasting host has not successfully received the live data frame 5-1 and the live data frame 5-2 of the data acquisition device 5 within the current scheduling time. In response to this situation, the lost live data frame of the target data acquisition device can be retransmitted with reference to the process described in the following embodiment. On the basis of the above embodiment, optionally, the process of controlling the target data acquisition device to retransmit the first live data frame during the idle sending period of other data acquisition devices can be: controlling the target data acquisition device to retransmit the first live data frame and the second live data frame according to the preset transmission rules during the idle sending period of other data acquisition devices.

[0033] It should be noted that the above-mentioned preset transmission rules can be set based on actual needs, as long as the first live broadcast data frame and the second live broadcast data frame are retransmitted during the idle transmission period of other data acquisition devices. This embodiment does not limit the specific method of retransmitting the first live broadcast data and the second live broadcast data frame during the idle transmission period of other data acquisition devices.

[0034] In an optional implementation, the process of controlling the target data acquisition device to retransmit the first live data frame and the second live data frame according to the preset transmission rule during the idle transmission period of other data acquisition devices may be: controlling the target data acquisition device to alternately retransmit the first live data frame and the second live data frame during the idle transmission period of other data acquisition devices. Figure 5 , taking the first live data frame as live data frame 5-2 and the second live data frame as live data frame 5-1 as an example, when the live data frame 5-2 is not successfully received, the live data frame 5-2 can be retransmitted before the next data acquisition device 1 is scheduled (that is, in the time period after the data acquisition device n sends the live data frame n-2 to before the data acquisition device 1 sends the live data frame 1-3), and the live data frame 5-1 can be retransmitted after the data acquisition device 1 is scheduled and before the data acquisition device 2 is scheduled, and so on, that is, avoiding the scheduling time of other data acquisition devices and alternately retransmitting the live data frame 5-1 and the live data frame 5-2, so as to successfully receive the live data frame 5-1 and the live data frame 5-2 as much as possible before the next scheduling time of the target data acquisition device 5 arrives.

[0035] In another optional implementation, the process of controlling the target data acquisition device to retransmit the first live data frame and the second live data frame according to the preset transmission rules during the idle transmission period of other data acquisition devices can also be: controlling the target data acquisition device to preferentially retransmit the first live data frame during the idle transmission period of other data acquisition devices, and then retransmitting the second live data frame after successfully receiving the first live data frame. Compared with the second live data frame, the first live data frame is closer to the scheduling time of the next live data frame of the target data acquisition device. By preferentially retransmitting the first live data frame, the first live data frame can be successfully received as much as possible before the next scheduling time of the target data acquisition device arrives, ensuring that the subsequent live data stream of the target data acquisition device is continuous, avoiding the problem of freeze or discontinuity in the live broadcast picture. Furthermore, the recording and broadcasting host not only supports the live broadcast function, but also supports the recording function of media data. By retransmitting the second live data frame, the integrity of the media data recorded locally by the recording and broadcasting host can be ensured.

[0036] Optionally, if the live data frame sent by the target data acquisition device is not successfully received for multiple consecutive times, it indicates that the wireless environment of the target data acquisition device is relatively poor, and the signal may be blocked or seriously interfered with. In this case, the recording and broadcasting host can output the machine position adjustment information; wherein, the machine position adjustment information is used to indicate the adjustment of the machine position of the target data acquisition device, improve the wireless environment of the target data acquisition device, and reduce the probability of loss of the live data frame, thereby avoiding the problem of freezing or intermittent live screen. For example, if the recording and broadcasting host fails to successfully receive the live data frame of the data acquisition device 5 for multiple times, the following information "It is recommended to adjust the machine position of the data acquisition device 5" can be output on the current display interface, and the user can be reminded by means of a sound alarm.

[0037] In this embodiment, when it is determined that there are multiple lost live data frames between the target data acquisition device and the recording and broadcasting host, the recording and broadcasting host can control the target data acquisition device to retransmit the first live data frame and the second live data frame according to the preset transmission rules during the idle sending period of other data acquisition devices. On the one hand, by retransmitting the first live data frame, it can ensure as much as possible that the subsequent live data stream of the target data acquisition device is continuous, avoiding the problem of freeze or discontinuity in the live broadcast picture. On the other hand, by retransmitting the second live data frame, the integrity of the locally recorded media data can be achieved.

[0038] In one embodiment, after the target data acquisition device retransmits the first live data frame, the recording and broadcasting host may successfully receive the first live data frame before the next scheduled time of the target data acquisition device arrives, or it may successfully receive the first live data frame after the next scheduled time of the target data acquisition device arrives. In this case, the recording and broadcasting host may process the first live data frame according to the following process. Based on the above embodiment, optionally, Figure 6 As shown, the method may also include:

[0039] S61. When a first live broadcast data frame is received, a frame identifier of the first live broadcast data frame is obtained.

[0040] When each data acquisition device sends a live data frame, it will carry a corresponding frame identifier in the live data frame, and the frame identifier indicates the playback order of each live data frame. The frame identifier can be the serial number of the playback order of each live data frame, or the sending time information of each live data frame. In this way, after receiving the first live data frame retransmitted by the target data acquisition device, the recording and broadcasting host can parse the first live data frame and obtain the frame identifier of the first live data frame from the parsing result.

[0041] S602: Determine whether the frame identifier is the current maximum frame identifier of the received target data acquisition device.

[0042] The recording and broadcasting host can also obtain the frame identifiers of other live data frames received from the target data acquisition device, and compare the frame identifier of the first live data frame with the frame identifiers of other live data frames to determine whether the frame identifier of the first live data frame is the current maximum frame identifier of the received target data acquisition device. If so, execute the following S603; if not, execute the following S604.

[0043] S603: Push the first live broadcast data frame to the live broadcast server.

[0044] When the frame identifier of the first live broadcast data frame is the current maximum frame identifier of the received target data acquisition device, it indicates that the first live broadcast data frame is the latest live broadcast data frame of the target data acquisition device. Then, the first live broadcast data frame can be pushed to the live broadcast server without the problem of time reversal.

[0045] S604: Fill the first live data frame into the recorded media data according to the frame identifier.

[0046] When the frame identifier of the first live broadcast data frame is not the current maximum frame identifier of the target data acquisition device that has been received, it indicates that the first live broadcast data frame is not the latest live broadcast data frame of the target data acquisition device, but a previously lost live broadcast data frame. During the live broadcast process, the recording and broadcasting host must push the stream in chronological order, so the recording and broadcasting host cannot push the first live broadcast data frame to the live broadcast server. For the first live broadcast data frame that cannot be pushed, the recording and broadcasting host can fill the first live broadcast data frame into the recorded media data according to the frame identifier of the first live broadcast data frame, thereby ensuring the integrity of the recorded media data.

[0047] In this embodiment, after receiving the first live broadcast data frame, if the frame identifier of the first live broadcast data frame is the current maximum frame identifier of the received target data acquisition device, the first live broadcast data frame is pushed to the live broadcast server, thereby satisfying the continuity of the live broadcast streaming; otherwise, the first live broadcast data frame is filled into the recorded media data, so that the locally recorded media data is complete, which is convenient for the subsequent playback and processing of the media data.

[0048] In one embodiment, optionally, if the first live data frame is still not received after a preset time period, the target data acquisition device may be controlled to store the first live data frame from the buffer area to the non-buffer area.

[0049] The preset time period may be related to whether the first live data frame can be pushed, and usually the preset time period is greater than the time difference between two schedulings of the target data acquisition device. That is, for the first live data frame that cannot be pushed, the target data acquisition device can be controlled to delete the first live data frame from the buffer area and store it in the non-buffer area, thereby reducing the memory usage of the target data acquisition device.

[0050] Optionally, after the live broadcast ends, the recording and broadcasting host can obtain the first live broadcast data frame from the non-buffered area of ​​the target data acquisition device, and process the recorded media data according to the first live broadcast data frame. For example, after the live broadcast ends, the recording and broadcasting host obtains the first live broadcast data frame from the non-buffered area of ​​the target data acquisition device through a wired network or a wireless network, and according to the log file recorded by the system, such as based on the frame identifier of the first live broadcast data frame, the first live broadcast data frame is re-added to the recorded media data, so that the recorded media data is more complete.

[0059] Based on the above embodiment, optionally, the above processing module is also used to output camera position adjustment information if the live broadcast data frame sent by the target data acquisition device is not successfully received for multiple consecutive times; wherein the camera position adjustment information is used to indicate adjustment of the camera position of the target data acquisition device.
