[0047] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0049] At present, in the process of voice communication, due to factors such as bandwidth, the number of retransmissions is generally one. Due to factors such as co-channel interference, voice data packet loss is inevitable, which is particularly prominent in long-distance calls and noisy air signals, resulting in noise and popping sounds in voice calls, seriously affecting user experience. For example, traditional True Wireless Stereo (TWS) Bluetooth headsets also have the same problem. Since both ears produce sound at the same time, they are particularly sensitive to data reliability and attach great importance to anti-interference capabilities.

[0050] In order to solve the problems of the prior art, the embodiments of the present invention provide a method and apparatus for compensating voice data of a wireless audio and video device group, a wireless audio and video device group and a computer storage medium. The following first introduces the method for compensating voice data of a wireless audio and video device group provided by the embodiments of the present invention.

[0051] Figure 1 The flowchart of a voice data compensation method of a wireless audio and video device group provided by an embodiment of the present invention is shown. The wireless audio and video device group includes a first device and a second device paired with the first device. Figure 1 As shown, the voice data compensation method of the wireless audio and video device group may include the following steps:

[0052] S101. When at least a first device receives a target voice data packet sent by a target device, the first device sends a target voice data packet to a second device.

[0053] In one embodiment, the first device may be a main Bluetooth headset, and the second device may be a secondary Bluetooth headset. In another embodiment, the first device may be a secondary Bluetooth headset, and the second device may be a main Bluetooth headset. The target device may be a mobile terminal, such as a mobile phone. The target voice data packet is a correct voice data packet.

[0054] In one embodiment, when the first device is a master device and the second device is a slave device, when at least the first device receives a target voice data packet sent by a target device, before the first device sends the target voice data packet to the second device, the method also includes: the first device establishes an asynchronous connectionless connection with the target device; the first device establishes a synchronous connection-oriented or extended synchronous connection-oriented connection with the target device.

[0055] In one embodiment, when at least the first device receives a target voice data packet sent by a target device, the first device sends a target voice data packet to a second device, including: when at least the first device receives the target voice data packet, the second device sends an empty data packet or a first voice data packet to the first device; when the first device determines that the empty data packet or the first voice data packet is erroneous, the first device sends the target voice data packet to the second device.

[0056] S102: The second device determines whether the target voice data packet is incorrect.

[0057] S103: When it is determined that the target voice data packet is correct, the first device and the second device send the target voice data packet to their respective voice output devices.

[0058] In one embodiment, the method also includes: when neither the first device nor the second device receives the target voice data packet, the first device sends the received second voice data packet to the second device, and the second device sends the received third voice data packet to the first device; the first device and the second device both compare the second voice data packet and the third voice data packet bit by bit to recover the target voice data packet.

[0059] In one embodiment, the method further includes: calculating a first retransmission rate between the target device and the first device; and calculating a second retransmission rate between the target device and the second device.

[0060] The voice data compensation method of the wireless audio and video device group, when at least the first device receives the target voice data packet sent by the target device, the first device sends the target voice data packet to the second device; the second device determines whether the target voice data packet is wrong; when it is determined that the target voice data packet is correct, the first device and the second device send the target voice data packet to their respective voice output devices. It can be seen that the method realizes mutual compensation of voice data packets, reduces the loss of voice data packets, and thus improves the quality of voice communication.

[0061] The embodiments of the present invention include but are not limited to Bluetooth (including classic Bluetooth and Bluetooth low Energy (BLE)) transmission methods during voice communication, and may also utilize real-time wireless transmission methods such as Wi-Fi to achieve mutual compensation for left and right ear voices, thereby reducing data loss rate and improving voice call quality.

[0062] The following takes the voice communication between a mobile phone and a Bluetooth headset (including a main headset and a secondary headset) as an example to illustrate the above content.

[0063] An ACL connection and a SCO connection or an eSCO connection is established between the main headset and the mobile phone. The main headset and the mobile phone can exchange information, while the secondary headset can only receive voice data packets sent by the mobile phone in one direction.

[0064] The mobile phone sends voice data packets to the main headset and the auxiliary headset. The main headset determines whether the voice data packet is received. When the main headset receives the voice data packet, it sends the voice data packet to the auxiliary headset. The auxiliary headset compares the voice data packet with the voice data packet it has received, and sends the correct voice data packet to the main headset. When the main headset does not receive the voice data packet, it sends an empty data packet to the auxiliary headset, and the auxiliary headset sends the voice data packet it has received to the main headset.

[0065] After the main earphone determines that the voice data packet sent by the auxiliary earphone is correct, the main earphone and the auxiliary earphone send the correct voice data packet to their respective upper layer protocol stacks and transmit it through the speaker.

[0066] It can be seen that the embodiment of the present invention has an air compensation mechanism for voice data packets. The transmission efficiency calculation after the mechanism is implemented is:

[0067] Assume that the retransmission rate between the mobile phone and the primary and secondary earphones is P(x), where x represents the distance between the mobile phone and the primary and secondary earphones, and P(x) changes linearly with x (x can also be other environmental variables, such as the degree of co-channel interference in the air channel). The retransmission rate between the primary and secondary earphones is temporarily fixed at P(0) (the relative positions of the primary and secondary earphones are temporarily unchanged, and P(0) will also change when the interference in the air channel increases).

[0068] Calculation of comprehensive retransmission rate:

[0069] It is a special case that the main and auxiliary earphones receive errors at the same time. At this time, the retransmission rate after compensation is P(y) = P(x)*P(x). In the case of simultaneous reception errors, the most likely possibility is to rely on the Programmable Logic Controller (PLC) for compensation. If air compensation is not possible, the erroneous data can be transmitted to each other and then compared bit by bit in order to achieve the possibility of data recovery.

[0070] Table 1 Calculation variable settings

[0071] Retransmission rate between the mobile phone and the primary and secondary headsets P(x) Variable, which changes linearly with x Retransmission rate between primary and secondary headphones P(0) Can be considered as a constant Retransmission rate P(y) Retransmission rate between mobile phone headsets before compensation Retransmission rate after compensation P(y)' Retransmission rate between mobile phone headsets after compensation

[0072] Table 2 Four scenarios

[0073]

[0074] Assume that the retransmission rate between the primary and secondary earphones is P(0) = 0.03, and the retransmission rates P(x) between the mobile phone and the primary and secondary earphones are 0.03, 0.07, and 0.09 respectively. Calculate the retransmission rate difference (both ears receive errors at the same time, and only one case is calculated temporarily):

[0075] Table 3

[0076] The main and sub earphones receive the wrong signal at the same time Main earphone pair Pair of earphones 0.00087219 0.028227 0.02820081 0.00474859 0.063147 0.06308841 0.00784971 0.076167 0.07936929

[0077] It can be seen that when P(0) is constant and small enough, that is, the communication between the primary and secondary earphones is very good, as P(x) increases, the improvement in the retransmission rate is greater.
