Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of network data transmission, in particular to a wireless local area network audio transmission monitoring method and device, computer equipment and storage medium. BACKGROUND

[0002] In the prior art, the encoding end accesses the HDMI input, and finally encodes the HDMI signal into video data (such as H264 and H265). The decoding end transmits the above-mentioned audio and video data to the decoding end through wireless transmission through WIFI, and the decoding end decodes the video data and finally converts it into HDMI signal output.

[0003] At present, data transmission can be carried out through TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) mode, but although the TCP mode transmission is not prone to packet loss, in order to ensure the transmission reliability and maintain the end-to-end connection, this method increases the retransmission mechanism, and when the timeout condition exists, the data packet will be retransmitted, which results in a certain delay in transmission, and there is a situation of audio lag or delay. Compared with the TCP mode, the UDP mode does not need to wait for the response of the opposite end device, and the transmission delay is lower, but the order, integrity and arrival rate of the audio data packet are not guaranteed, and the reliability is lower, and packet loss is prone to occur. Therefore, due to the defects of this mode, audio discontinuity, frame skipping and other situations occur, which is unacceptable to users who have transmission speed requirements and transmission reliability requirements for audio data transmission.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figure 1 This is a wireless local area network audio transmission monitoring method according to an embodiment of the present invention, which includes the following steps: S101. Obtain the audio sampling rate ratio of the audio transmitter. In this embodiment, the audio sampling rate ratio is the ratio between the sampling points and the sampling rate. The audio transmitter sends audio data to the audio transmission terminal in the form of broadcast. During this period, the audio transmission terminal receives audio data packets and obtains the current audio sampling rate ratio, that is, reads the audio sampling points and sampling rate.

[0023] S102. Perform sampling adjustment processing on the audio sampling rate ratio and the preset sampling rate ratio to obtain the sampling rate adjustment. It can be understood that the audio transmitter sends audio data to the audio transmission terminal in the form of broadcast. During this period, the audio transmission terminal receives audio data packets and obtains the current audio sampling rate ratio, that is, reads the audio sampling points and sampling rate. Then, the audio sampling rate ratio and the preset sampling rate ratio are subjected to sampling adjustment processing to obtain the difference between the current audio sampling rate ratio and the preset sampling rate ratio, thereby confirming whether there is a situation where the audio data packets are sent out in a timeout.

[0024] S103. Based on the sampling rate adjustment, an audio packet retransmission enable / disable signal is sent to the audio transmission terminal to adjust the audio data packet retransmission mode at the audio transmitter. In this embodiment, the sampling rate adjustment is the sampling rate adjustment error value between the audio sampling rate ratio and the preset sampling rate ratio. It is used to reflect whether the audio data acquired by the audio transmission terminal has a timeout. Then, based on the sampling rate adjustment error value between the audio sampling rate ratio and the preset sampling rate ratio, it is determined whether to request retransmission. When the timeout time is less than the duration of the content of one frame in the audio data packet, an audio packet retransmission enable / disable signal can be sent to request retransmission; when the timeout time exceeds the duration of the content of one frame in the audio data packet, it indicates that retransmission is not very meaningful, and an audio packet retransmission disable / disable signal is sent to stop the retransmission request. That is, the request to retransmit data packets to the audio transmitter is allowed or prohibited based on the sampling rate adjustment, thus ensuring the reliability and stability of audio data transmission. Further, the audio packet retransmission enable / disable signal includes an audio packet retransmission enable / disable signal and an audio packet retransmission disable / disable signal.

[0025] Specific steps are as follows Figure 2 As shown, the obtained sampling rate adjustment is used to reflect whether the audio data has timed out. If there is no timeout, no processing is done. If there is a timeout, it indicates that there is a timeout. Then it is determined whether the timeout time exceeds the content time of one frame of the audio data packet. If it exceeds the time, the retransmission request is stopped and the current audio data packet is discarded. Otherwise, a retransmission is requested.

[0026] In the above embodiments, the audio transmission will determine the timeout status of the audio data based on the audio sampling rate ratio. When there is a certain timeout, a request can be made to the audio transmitter to resend the data packet to ensure the integrity of the audio data. When the timeout time exceeds the duration of the sound content carried by a frame, it means that the timeout time has been far exceeded. At this time, the current data packet can be discarded to ensure the continuity of the audio. This method can achieve the reliability and stability of audio transmission and meet the audio quality needs of more users.

[0027] In one embodiment, obtaining the audio sampling rate ratio of the audio transmitter includes obtaining the ratio of the number of sampling points to the sampling rate of the audio transmitter. Specifically, the ratio of the number of sampling points to the sampling rate of the audio transmitter is obtained through the audio transmission terminal, that is, the number of sampling points and the sampling rate are obtained successively, and finally divided to obtain the ratio. This is to prepare for subsequent judgment on whether the ratio has an error with a preset ratio. The ratio of the number of sampling points to the sampling rate is the duration of the content carried by one frame.

[0028] In one embodiment, the step of performing sampling adjustment processing on the audio sampling rate ratio and the preset sampling rate ratio includes: calculating the least squares difference between the audio sampling rate ratio and the preset sampling rate ratio. In this embodiment, after obtaining the ratio of the number of sampling points to the sampling rate at the audio transmitter, the least squares difference is calculated between this ratio and the preset sampling rate ratio to determine the degree of difference between the ratio and the preset value, thereby determining whether to request a retransmission of the data packet.

[0029] In one embodiment, the preset sampling rate ratio is 20 to 22 milliseconds. Further, the preset sampling rate ratio is 21.33 milliseconds, with 21.33 milliseconds serving as a threshold for transmission timeout, thereby better confirming the transmission timeout status of each video data point. The preset sampling rate ratio is a preset ratio between the preset number of sampling points and the preset sampling rate.

[0030] In one embodiment, the step of sending an audio packet retransmission enable / disable signal to the audio transmission terminal based on the sampling rate adjustment to adjust the audio data packet retransmission mode at the audio transmitter includes: Check whether the sampling rate adjustment is greater than or equal to the preset sampling rate adjustment; When the sampling rate adjustment is greater than or equal to the preset sampling rate adjustment, a retransmission prohibition signal is sent to the audio transmission terminal to prevent the audio transmission terminal from issuing retransmission requests.

[0031] In a specific embodiment, the ratio of the number of sampling points to the sampling rate at the audio transmitter is obtained through the audio transmission terminal. This involves obtaining the number of sampling points and the sampling rate sequentially, dividing them, and then obtaining the ratio. This ratio is then compared to a preset sampling rate ratio using least squares difference calculation to determine the degree of difference between the ratio and the preset value, i.e., the sampling rate adjustment. This difference is used to determine whether to request a retransmission of the data packet, where the sampling rate adjustment represents the audio transmission timeout. Subsequently, it is determined whether the sampling rate adjustment is greater than or equal to the preset sampling rate adjustment, where the preset sampling rate adjustment is the reference duration of the sound content carried in one frame. When the sampling rate adjustment is greater than or equal to the preset sampling rate... During adjustment, it indicates that the audio data acquired by the audio transmission terminal has a certain timeout, and the timeout period exceeds the reference duration of the sound content carried in one frame of the audio data. If the data packet is resent to the audio transmission terminal with the transmission timeout at this time, the audio acquired by the audio transmission terminal will have a large difference from that of other audio transmission terminals. At this time, a retransmission prohibition signal is sent to the audio transmission terminal to prevent the audio transmission terminal from issuing retransmission requests. That is, the current data packet is discarded, and no action is taken even if a retransmission is requested, so as to ensure that the audio transmission terminal can play the audio synchronously, thereby ensuring the stability and reliability of the transmitted audio data packets.

[0032] In one embodiment, the step of detecting whether the sampling rate adjustment is greater than or equal to a preset sampling rate adjustment further includes: when the sampling rate adjustment is less than the preset sampling rate adjustment, sending a retransmission pass signal to the audio transmission terminal so that the audio transmission terminal requests the audio transmitter to retransmit the audio data packet.

[0033] It is understandable that after obtaining the sampling rate adjustment through the least squares difference, it is determined whether the sampling rate adjustment is greater than or equal to the preset sampling rate adjustment. When the sampling rate adjustment is less than the preset sampling rate adjustment, it indicates that the audio data acquired by the audio transmission terminal has timed out for a certain period of time, but the timeout period does not exceed the reference duration of the sound content carried in a frame of the audio data. At this time, a retransmission pass signal is sent to the audio transmission terminal so that the audio transmission terminal requests the audio transmitter to retransmit the audio data packet. In other words, the audio transmission terminal is allowed to request the audio transmitter to retransmit the audio data packet to ensure that the audio transmission terminal can acquire the audio data completely, ensure the integrity of the audio transmission packet, and prevent audio frame skipping.

[0034] Specifically, the audio transmitter broadcasts audio data to multiple audio transmission terminals, allowing each terminal to acquire the current audio sampling rate ratio. The least-squares difference between this ratio and a preset rate ratio is then calculated to obtain the sampling rate adjustment, which is used to determine the audio data transmission timeout. When the sampling rate adjustment is greater than or equal to the preset rate adjustment, it indicates that the audio data transmission terminal's timeout exceeds the reference duration of a single frame of sound content in the audio data. This means the transmitted data packet has become meaningless, even if it is transmitted via unicast. When an audio transmission terminal experiences a timeout and resends a data packet, the audio played by that terminal may differ significantly from the audio played by other audio transmission terminals, thus the current data packet is discarded. When the sampling rate adjustment is less than the preset rate adjustment, it indicates that the timeout period of the audio data acquired by the audio transmission terminal has not exceeded the reference duration of the sound content carried in one frame of the audio data. In this case, the audio transmission terminal can request the audio transmitter to resend the data packet lost due to the timeout, so that the audio transmitter can resend the data packet to the audio transmission terminal with the timeout via unicast to compensate for the number of frames lost in the current audio data packet and ensure the integrity of the audio data packet. For example, if an audio frame has 1024 sampling points and a sampling rate of 48kHz, theoretically, the duration of the sound content carried by one frame is 1024 / 48000 ≈ 0.02133 seconds = 21.33 milliseconds. Therefore, 21.33 milliseconds is used as the base duration of the sound content carried by one frame in the audio data. As another example, if an audio frame has 1024 sampling points and a sampling rate of 44.1kHz, theoretically, the duration of the sound content carried by one frame is 1024 / 44100 ≈ 0.02321 seconds = 23.21 milliseconds. Therefore, 23.21 milliseconds is used as the base duration of the sound content carried by one frame in the audio data.

[0035] This addresses the issue of audio data packets having a synchronization relationship with the video, specifically the degree of correspondence between the audio and each frame of the video, in order to resolve audio inconsistencies during video playback.

[0036] When transmitting audio data, video footage is also transmitted. Since there is an audio-video synchronization relationship between audio and video, if there is a delay in the audio transmission process, the number of each frame of the audio will not correspond to the number of each frame of the video. This will result in the audio frame being ahead or behind the video frame. The above situation will cause the audio frame and video frame to be out of sync during video playback.

[0037] To address the above situation, in one embodiment, an audio packet retransmission enable / disable signal is sent to the audio transmission terminal based on the sampling rate adjustment to adjust the audio data packet retransmission mode at the audio transmitter. This further includes: S91. Obtain the audio-visual synchronization timestamp from the audio transmitter; S92. Detect whether the audio-visual synchronization timestamp is less than or equal to the preset synchronization timestamp; S93. When the audio-visual synchronization timestamp is greater than the preset synchronization timestamp, send an audio packet discard signal to the audio transmission terminal to directly discard the data packets corresponding to the out-of-sync audio frames.

[0038] In this embodiment, after executing S103, the system can allow or prohibit the audio transmission terminal from requesting retransmission of data packets from the audio transmitter based on the timeout level of the audio data acquisition by the audio transmission terminal. Even if retransmission of audio data packets or discarding the current audio data packets is used to ensure low latency and reliable audio data transmission, it is still uncertain whether each frame of the audio corresponds to each frame of the video. Therefore, the audio-visual synchronization timestamp of the audio transmitter is first obtained to determine the correspondence between each frame of the audio and each frame of the video. Then, it is checked whether the audio-visual synchronization timestamp is less than or equal to a preset synchronization timestamp to determine whether there is a time difference between each frame of the audio and each frame of the video. The audio-visual synchronization timestamp is... The absolute time difference between the synchronized frames of audio and video is considered. When the audio-video synchronization timestamp is greater than the preset synchronization timestamp, it indicates that at least one frame of audio is out of sync with at least one frame of video, or even worse, the audio frame arrives after the video frame has finished playing, or vice versa (i.e., the video and audio frames are severely out of sync). In this case, the late audio frame is not worth retransmitting. The system sends an audio packet discard signal to the audio transmission terminal to directly discard the data packet corresponding to the out-of-sync audio frame. Even if the audio transmission terminal issues a retransmission request, it will not be processed to ensure that the audio frames can correspond to the video frames in subsequent audio data transmission, thus ensuring the reliability and low latency of audio transmission. The specific steps are as follows: Figure 3 As shown. Furthermore, the preset synchronization timestamp is the base time difference corresponding to the number of synchronized frames of audio and video, for example, 0 seconds.

[0039] For example, after obtaining the audio-visual synchronization timestamp from the audio transmitter, the audio data has 30 frames and the video data has 30 frames. However, the 27th frame of the audio data corresponds to the 30th frame of the video data, resulting in no sound in the video data after the 27th frame. There is a lack of synchronization between the audio and video frames. Even if the audio data after the 27th frame arrives, the 30 frames of video data have already finished playing, making it worthless to resend the audio data after the 27th frame. Therefore, the audio data packet after the 27th frame is discarded.

[0040] In another embodiment, after detecting whether the audio-visual synchronization timestamp is less than or equal to a preset synchronization timestamp, the method further includes: If the audio-visual synchronization timestamp is less than or equal to the preset synchronization timestamp, return and re-execute S101.

[0041] It is understandable that the audio-visual synchronization timestamp of the audio transmitter is first obtained to determine the correspondence between each frame of the audio and each frame of the video. Then, it is checked whether the audio-visual synchronization timestamp is less than or equal to the preset synchronization timestamp to determine whether there is a time difference between each frame of the audio and each frame of the video. The audio-visual synchronization timestamp is the absolute time difference corresponding to the number of synchronized frames of the audio and video. When the audio-visual synchronization timestamp is less than or equal to the preset synchronization timestamp, it indicates that the absolute time difference corresponding to the number of synchronized frames of the audio and video is less than the preset synchronization timestamp, that is, less than or equal to 0 seconds. This means that the time interval of each frame of the audio and each frame of the video is synchronized. At this time, no processing is required, that is, return to the current step and execute S101 to obtain the audio sampling rate ratio of the next audio transmitter, that is, to check whether the next audio data packet has a timeout.

[0042] For example, after obtaining the audio-visual synchronization timestamp of the audio transmitter, the audio data has 30 frames and the video data has 30 frames. Frames 1-30 in the audio data correspond to frames 1-30 in the video data, indicating that the audio frames and video frames are synchronized. At this time, no data packet is discarded, and the audio sampling rate ratio of the next audio transmitter is obtained, which means that the next audio data packet may have a timeout.

[0043] All the aforementioned preset variables are set in the database for easy retrieval. Different preset variables are placed in different storage units, i.e., in different storage stacks. Moreover, audio-visual synchronization timestamps, preset synchronization timestamps, etc., can all be collected by relevant components, such as clock chips.

[0044] This disclosure also provides a wireless local area network (WLAN) audio transmission monitoring device. The WLAN audio transmission monitoring device employs the WLAN audio transmission monitoring method described in any embodiment, including an audio transmission acquisition module, an audio sampling processing module, and an audio retransmission module. The audio transmission acquisition module is used to acquire the audio sampling rate ratio of the audio transmitter. The audio sampling processing module is used to perform sampling adjustment processing on the audio sampling rate ratio and a preset rate ratio to obtain a sampling rate adjustment. The audio retransmission module is used to send an audio packet retransmission enable / disable signal to the audio transmission terminal based on the sampling rate adjustment to adjust the audio data packet retransmission mode at the audio transmitter. Specifically, the audio transmission will determine the timeout status of the audio data based on the audio sampling rate ratio. When a timeout occurs, a request can be made to the audio transmitter to retransmit data packets to ensure the integrity of the audio data. When the timeout exceeds the duration of the sound content carried by a frame, it indicates that the timeout period has been far exceeded. In this case, the current data packet can be discarded to ensure the continuity of the audio. This method can achieve the reliability and stability of audio transmission, meeting the audio quality needs of more users.
