[0089] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0090] Low-power Bluetooth audio broadcasting technology is becoming increasingly popular. The Bluetooth Special Interest Group (SIG), the international standardization organization for the Bluetooth protocol, has proposed a connectionless broadcast audio sharing technology, which allows Bluetooth headsets (Bluetooth devices) to listen to music without being connected to the audio source device that plays the audio, greatly improving the flexibility of audio sharing.

[0091] According to the Bluetooth technology protocol standard, multiple audio source devices can broadcast audio data on the Bluetooth low energy advertising channel and data channel. When any two audio source devices transmit audio data on the same channel, they will interfere with each other, causing the Bluetooth device to be unable to receive audio data normally. For example, see Figure 1 The diagram shows a conflict between audio source devices when broadcasting audio data. Figure 1 Taking two audio source data as an example, audio source device A and audio source device B share media audio through broadcasting at the same time. Although the two audio devices use Bluetooth frequency hopping technology when transmitting data through 2.4GHZ radio frequency technology, during the long data transmission process, the two devices still have a high probability of transmitting data on the same channel at the same time, and conflicts will occur at this time.

[0092] In the related art, when transmitting data, Bluetooth frequency hopping technology is used, for example, see Figure 2The schematic diagram of broadcast audio data shown in the figure, first, the sound source device sends an ADV_EXT_IND broadcast packet on any of the primary advertising channels 37, 38 and 39, and the ADV_EXT_IND broadcast packet carries AuxPtr data, wherein the AuxPtr data includes the channel and time point of the AUX_ADV_IND broadcast packet. Then, the sound source device sends an AUX_ADV_IND broadcast packet on any of the second-type secondary advertising channels 0-36, and the AUX_ADV_IND broadcast packet carries SyncInfo data, wherein the SyncInfo data includes the channel and time point of the AUX_SYNC_IND broadcast packet. Then, the sound source device sends an AUX_SYNC_IND broadcast packet on any of the second-type secondary advertising channels 0-36, and the AUX_SYNC_IND broadcast packet carries BIGInfo data, wherein the BIGInfo data includes the channel and time point of the audio data packet. Finally, the audio device sends an audio data packet on any of the general-purpose channels 0-36. For a Bluetooth device, after receiving the ADV_EXT_IND broadcast packet, the Bluetooth device obtains the channel and time point of the audio data packet transmission through AuxPtr data, SyncInfo data and BIGInfo data in sequence, and monitors the audio data packet at the corresponding time point and channel. Among them, the second type of secondary broadcast channel is the same as the general channel.

[0093] In the above-mentioned related technologies, although audio data packets and broadcast packets such as AUX_ADV_IND, AUX_SYNC_IND, etc. are sent in a frequency hopping manner, when multiple audio source devices are in the same environment, there is still a high probability that two audio source devices transmit data on the same channel, thereby causing interference.

[0094] In response to the above problems, an embodiment of the present disclosure provides a method for transmitting audio data, wherein a first device first obtains first broadcast information, that is, obtains at least one occupied first broadcast channel and a first time period of occupying the first broadcast channel, and then determines second broadcast information based on the first broadcast information, where the second broadcast information is used to characterize the second broadcast channel and the second time period of occupying the second broadcast channel. The second broadcast channel is a channel used to transmit the audio data of the first device, the second broadcast channel is different from the first broadcast channel, and / or the second time period is different from the first time period. Finally, in the second time period, the audio data of the first device is transmitted through the second broadcast channel, which can avoid the first device and other devices from transmitting audio data on the same channel at the same time, that is, avoid mutual interference between audio data of different devices, thereby reducing the packet loss rate of the audio data and improving the effective transmission rate.

[0095] In the disclosed embodiment, the execution subject is a first device (i.e., a sound source device), and the first device is an electronic device such as a mobile phone, a tablet, a laptop computer, a wearable device, etc. that can be connected to a Bluetooth device.

[0096] Figure 3 is a flowchart of a method for transmitting audio data according to an exemplary embodiment, which is executed by a first device, see Figure 3 , the method comprises the following steps:

[0097] Step S301: Acquire first broadcast information, where the first broadcast information includes at least one first broadcast channel that is monitored and occupied and a first time period of occupying the first broadcast channel.

[0098] Among them, the first broadcast information is the broadcast information of other devices monitored by the first device. The first broadcast information can be one or more. For example, the first broadcast information can be the broadcast information when a second device transmits audio data. Multiple first broadcast information is the broadcast information when multiple second devices transmit audio data.

[0099] The first broadcast information includes at least one first broadcast channel that has been monitored and occupied and a first time period of occupying the first broadcast channel. The first broadcast channel is a channel that is currently occupied among the channels used to transmit data. For example, the first broadcast channel can be any one of the second-class secondary broadcast channels 0-36. The first time period is the time period of occupying the first broadcast channel. Optionally, the first time period can be a continuous time period, or a time period composed of multiple discontinuous time periods. Alternatively, the first time period can also be a certain time point.

[0100] It should be noted that in addition to the first broadcast channel and the first time period, the first broadcast information may also include other information. For example, the first broadcast information may also include transmitted audio data, sending device information, receiving device information, etc. In the embodiments of the present disclosure, there is no restriction on other information included in the first broadcast information.

[0101] Step S302: Based on the first broadcast information, determine the second broadcast information, where the second broadcast information is used to characterize a second broadcast channel and a second time period occupying the second broadcast channel, where the second broadcast channel is a channel used to transmit audio data of the first device; wherein the second broadcast channel is different from the first broadcast channel, and / or the second time period is different from the first time period.

[0102] In the disclosed embodiment, in order to avoid mutual interference of audio data of different devices, it is necessary to make the audio data of different devices transmitted through different channels, or to transmit through the same channel but occupy different time periods of the channel, that is, to ensure that the audio data of different devices are not transmitted through the same channel in the same time period. To achieve this purpose, it is necessary to determine the second broadcast information of the first device based on the acquired first broadcast information.

[0103] The second broadcast information is used to characterize the second broadcast channel and the second time period occupying the second broadcast channel, the second broadcast channel is different from the first broadcast channel, and / or the second time period is different from the first time period. That is, the second broadcast channel and the second time period need to satisfy at least one of the following: the second broadcast channel is different from the first broadcast channel; the second time period is different from the first time period.

[0104] The second broadcast channel is a channel for transmitting audio data of the first device, and the audio data may be music, video sound, and the second broadcast channel is an unused channel in the channels for transmitting data, for example, the second broadcast channel is any unused one of the second-class secondary broadcast channels 0-36. The second time period is different from the first time period, which means that the second time period does not overlap with the first time period. For example, if the first time period is 8:00-8:01, the second time period may be any time period except 8:00-8:01. Optionally, the second time period may also be a certain time point.

[0105] It should be noted that, similar to the first broadcast information, the second broadcast information may include other information in addition to the second broadcast channel and the second time period. For example, the second broadcast information may also include transmitted audio data, sending device information, receiving device information, etc. In the embodiments of the present disclosure, there is no restriction on other information included in the second broadcast information.

[0106] Step S303: In a second time period, the audio data of the first device is transmitted through a second broadcast channel.

[0107] For the first device, after determining the second broadcast channel and the second time period, the audio data of the first device can be transmitted through the second broadcast channel in the second time period.

[0108] According to the method provided by the embodiment of the present disclosure, the first device first obtains the first broadcast information, that is, obtains at least one occupied first broadcast channel and the first time period of occupying the first broadcast channel, and then determines the second broadcast information based on the first broadcast information, where the second broadcast information is used to characterize the second broadcast channel and the second time period of occupying the second broadcast channel, the second broadcast channel is a channel used to transmit the audio data of the first device, the second broadcast channel is different from the first broadcast channel, and / or the second time period is different from the first time period, and finally, in the second time period, the audio data of the first device is transmitted through the second broadcast channel, which can avoid the first device and other devices from transmitting audio data on the same channel at the same time, that is, avoid mutual interference of audio data of different devices, thereby reducing the packet loss rate of audio data and improving the effective transmission rate.

[0109] In some embodiments, when the first device determines the second broadcast information based on the first broadcast information, the first device may first obtain the initial broadcast information, and then update the initial broadcast information according to the first broadcast information to obtain the second broadcast information. In this way, it is possible to avoid introducing other information when generating the initial broadcast information; or, the first device may directly determine the second broadcast information based on the first broadcast information, without first obtaining the initial broadcast information, and may obtain the second broadcast information more quickly. Figure 4 and Figure 5 The embodiments shown illustrate these two implementations:

[0110] Figure 4 is a flowchart of another method for transmitting audio data according to an exemplary embodiment, which is executed by a first device, see Figure 4 , the method comprises the following steps:

[0111] Step S401: monitor all broadcast channels in the spatial area where the first device is located.

[0112] In the embodiment of the present disclosure, the first device monitors all broadcast channels in the spatial area where it is located to determine whether there are other devices currently transmitting audio data through the broadcast channel. The spatial area where the first device is located is an area with the first device as the center and a preset distance as the radius. For example, the preset distance is 15 meters, and all broadcast channels within 15 meters of the first device are monitored. All broadcast channels refer to broadcast channels used for Bluetooth transmission. For example, all broadcast channels include primary broadcast channels 37-39 and second-class secondary broadcast channels 0-36.

[0113] In some embodiments, after the first device turns on the Bluetooth function, it monitors all broadcast channels in the spatial area where the first device is located once every preset time period. For example, the first device monitors all broadcast channels in the spatial area where the first device is located once every 1 minute.

[0114] In some embodiments, when the first device turns on the Bluetooth function and determines that audio data needs to be transmitted, it monitors all broadcast channels in the spatial area where the first device is located to obtain the usage of the broadcast channels in real time.

[0115] Step S402: when it is monitored that the second device transmits audio data through any broadcast channel, first broadcast information occupying the broadcast channel is obtained.

[0116] When it is monitored that the second device transmits audio data through any broadcast channel, it means that the broadcast channel has been occupied. At this time, the first broadcast information occupying the broadcast channel is obtained. The first broadcast information includes the occupied broadcast channel and the time period of occupying the broadcast channel, that is, the first broadcast information includes the first broadcast channel and the first time period.

[0117] In some embodiments, the first broadcast information is recorded in a channel usage list, which includes an occupied broadcast channel and a time period for occupying the broadcast channel. There is a corresponding relationship between the broadcast channel and the time period, and the same broadcast channel can correspond to different time periods, and the same time period can correspond to different broadcast channels.

[0118] It should be noted that after obtaining the first broadcast information, the first device can continue to monitor all broadcast channels. When a new occupied broadcast channel and a time period occupied by the broadcast channel are monitored, the newly monitored broadcast channel and time period are added to the channel usage list; or when it is monitored that an occupied broadcast channel and a time period occupied by the broadcast channel are no longer occupied, the no longer occupied broadcast channel and time period are deleted from the channel usage list.

[0119] Step S403: Acquire initial broadcast information of the first device, where the initial broadcast information is used to represent an initial broadcast channel and an initial time period for occupying the initial broadcast channel.

[0120] The initial broadcast information is the broadcast information generated by the first device. When generating the initial broadcast information, the first device does not consider whether the channel and time period are the same as the channels and time periods occupied by other devices. Therefore, the initial broadcast channel may be the same as the first broadcast channel, and / or the initial time period may be the same as the first time period. Optionally, the initial broadcast channel is a channel randomly selected from all broadcast channels, and the first time period is a time period close to the current time point.

[0121] It should be noted that, similar to the second broadcast information, the initial broadcast information may include other information in addition to the initial broadcast channel and the initial time period. For example, the initial broadcast information may also include transmitted audio data, sending device information, receiving device information, etc. In the embodiments of the present disclosure, there is no restriction on other information included in the initial broadcast information.

[0122] Step S404: determining second broadcast information based on the initial broadcast channel, the initial time period and the first broadcast information.

[0123] In the embodiment of the present disclosure, whether the initial broadcast information needs to be updated is determined based on whether the initial broadcast channel is the same as the first broadcast channel and whether the initial time period is the same as the first time period to obtain the second broadcast information.

[0124] In some embodiments, when the initial broadcast channel is different from the first broadcast channel, and / or the initial time period is different from the first time period, the initial broadcast information is determined as the second broadcast information. If the initial broadcast channel is different from the first broadcast channel, the audio data of the first device and the audio data of other devices are transmitted through different broadcast channels and will not interfere with each other. If the initial time period is different from the first time period, the audio data of the first device and the audio data of other devices are transmitted in different time periods and will not interfere with each other. Therefore, if the initial broadcast channel is different from the first broadcast channel, and / or the initial time period is different from the first time period, the audio data will not interfere with each other, so that the initial broadcast channel is different from the first broadcast channel, and / or the initial time period is different from the first time period, the audio data will not interfere with each other, thereby directly determining the initial broadcast information as the second broadcast information, and there is no need to modify the initial broadcast channel and the initial time period.

[0125] In some embodiments, when the initial broadcast channel is the same as the first broadcast channel, and the initial time period is the same as the first time period, the initial broadcast information is updated to obtain the second broadcast information. If the initial broadcast channel is the same as the first broadcast channel, and the initial time period is the same as the first time period, then the audio data of the first device and the audio data of other devices will be transmitted through the same broadcast channel at the same time, and will interfere with each other. Therefore, the initial broadcast information needs to be updated so that the updated time period is different from the first time period, and / or the updated broadcast channel is different from the first broadcast channel, so as to obtain the second broadcast information. Optionally, when updating the broadcast channel, the initial broadcast channel is modified to a randomly selected channel different from the first broadcast channel.

[0126] Optionally, the initial time period is updated to a second time period different from the first time period, and / or the initial broadcast channel is updated to a second broadcast channel different from the first broadcast channel, to obtain the second broadcast information.

[0127] In some embodiments, updating the initial broadcast channel to a second broadcast channel different from the first broadcast channel includes: generating a random number; and determining the second broadcast channel based on the initial broadcast channel and the random number. The random number is a value randomly generated by the first device, and the random number can be any value.

[0128] Optionally, since the broadcast channel for transmitting audio data is fixed, for example, the broadcast channel is 0-36, and the sum of the initial broadcast channel and the random number may exceed 36. In this case, when the sum of the initial broadcast channel and the random number is less than or equal to the preset threshold, the sum of the initial broadcast channel and the random number is determined as the second broadcast channel. Among them, the preset threshold is the largest broadcast channel. When the sum of the initial broadcast channel and the random number is less than or equal to the preset threshold, it means that the sum of the initial broadcast channel and the random number is still an available channel. Therefore, the sum of the initial broadcast channel and the random number is directly determined as the second broadcast channel. For example, if the initial broadcast channel is 5 and the random number is 3, then the second broadcast channel is determined to be 8.

[0129] Alternatively, when the sum of the initial broadcast channel and the random number is greater than a preset threshold, the mapping channel corresponding to the sum of the initial broadcast channel and the random number is determined according to a preset mapping relationship, and the mapping channel is determined as a second broadcast channel; wherein the preset mapping relationship is used to characterize the relationship between a numerical value greater than the preset threshold and the corresponding mapping channel, and the mapping channel is less than the preset threshold. When the sum of the initial broadcast channel and the random number is greater than the preset threshold, it means that the sum of the initial broadcast channel and the random number is not an available channel. Therefore, according to the preset mapping relationship, an available mapping channel is determined, and the mapping channel is determined as the second broadcast channel. For example, the broadcast channels are 0-36, and there are 37 broadcast channels in total. The preset mapping relationship is the remainder of the sum of the initial broadcast channel and the random number divided by 37. When the initial broadcast channel is 30 and the random number is 10, the second broadcast channel is determined to be 3.

[0130] It should be noted that when the broadcast channel determined based on the initial broadcast channel and the random number is still an occupied broadcast channel, the second broadcast channel is determined based on the determined broadcast channel and the random number, and the implementation method of determining the second broadcast channel based on the determined broadcast channel and the random number is the same as the implementation method of determining the second broadcast channel based on the initial broadcast channel and the random number. Alternatively, a random number is regenerated, and the second broadcast channel is determined based on the initial broadcast channel and the regenerated random number.

[0131] In some embodiments, when the initial time period is the same as the first time period and the initial broadcast channel is the same as the first broadcast channel, the initial broadcast channel is updated to a second broadcast channel different from the first broadcast channel, and the initial time period is determined to be the second time period.

[0132] Step S405: In a second time period, the audio data of the first device is transmitted through a second broadcast channel.

[0133] The first device broadcasts the second broadcast information, and the third device receives the second broadcast information, and the third device is a device for receiving audio data. For the third device receiving audio data, the third device receives the second broadcast information, determines the second time period and the second broadcast channel based on the received second broadcast information, and receives the audio data of the first device through the second broadcast channel in the second time period.

[0134] In some embodiments, the second broadcast information is used to characterize an initial broadcast channel, a first identifier corresponding to the initial broadcast channel, a second broadcast channel, a second identifier corresponding to the second broadcast channel, and a second time period, the first identifier is used to characterize the channel before modification, the second identifier is used to characterize the channel after modification, the first identifier is a pre-set identifier used to characterize the channel as the channel before modification, the second identifier is a pre-set identifier used to characterize the channel as the channel before modification, and the first identifier and the second identifier are identifiers permitted by the Bluetooth protocol standard. The third device receives the second broadcast information, determines that the second broadcast channel is a channel for transmitting audio data based on the first identifier and the second identifier, and receives the audio data of the first device through the second broadcast channel in the second time period.

[0135] According to the method provided by the embodiment of the present disclosure, the first device first obtains the first broadcast information, then determines the second broadcast information based on the first broadcast information and the initial broadcast information, and finally transmits the audio data of the first device through the second broadcast channel in the second time period. This can avoid the first device and other devices from transmitting audio data on the same channel at the same time, that is, avoid mutual interference between audio data of different devices, thereby reducing the packet loss rate of audio data and improving the effective transmission rate.

[0136] Figure 5 is a flowchart of another method for transmitting audio data according to an exemplary embodiment, which is executed by a first device, see Figure 5 , the method comprises the following steps:

[0137] Step S501: monitor all broadcast channels in the spatial area where the first device is located.

[0138] Step S502: when it is monitored that the second device transmits audio data through any broadcast channel, first broadcast information occupying the broadcast channel is obtained.

[0139] The implementation of steps S501 and S502 refers to the above steps S401 and S402, which will not be described in detail here.

[0140] Step S503: Determine a second broadcast channel and a second time period based on the first broadcast channel and the first time period.

[0141] Step S504: determine second broadcast information based on the second broadcast channel and the second time period.

[0142] In the embodiment of the present disclosure, in order to prevent the first device from transmitting audio data on the same channel at the same time as other devices, when determining the second broadcast information, first determine a second broadcast channel different from the first broadcast channel based on the first broadcast channel, and / or determine a second time period different from the first time period based on the first time period, and then determine the second broadcast information based on the second broadcast channel and the second time period.

[0143] In some embodiments, based on the first broadcast channel, a second broadcast channel different from the first broadcast channel is determined, and a second time period is determined, and the second time period may be the same as or different from the first time period. Alternatively, based on the first time period, a second time period different from the first time period is determined, and a second broadcast channel is determined, and the second broadcast channel may be the same as or different from the first broadcast channel.

[0144] Step S505: In a second time period, the audio data of the first device is transmitted through a second broadcast channel.

[0145] According to the method provided by the embodiment of the present disclosure, the first device first obtains the first broadcast information, then determines the second broadcast information based on the first broadcast information, and finally transmits the audio data of the first device through the second broadcast channel in the second time period. This can avoid the first device and other devices from transmitting audio data on the same channel at the same time, that is, avoid mutual interference between audio data of different devices, thereby reducing the packet loss rate of audio data and improving the effective transmission rate.

[0146] In some embodiments, in order to further avoid interference, frequency hopping transmission is adopted, that is, when transmitting audio data, multiple broadcast packets can be transmitted in sequence through different broadcast channels.

[0147] The second broadcast information includes a first broadcast packet, the first broadcast packet includes first data, the first data is used to characterize the third broadcast channel used to transmit the second broadcast packet and the third time period occupied by the third broadcast channel, the second broadcast packet includes second data, the second data is used to characterize the fourth broadcast channel used to transmit the third broadcast packet and the fourth time period occupied by the fourth broadcast channel, the third broadcast packet includes third data, the third data includes the fifth broadcast channel used to transmit the audio data packet and the fifth time period occupied by the fifth broadcast channel, and the audio data packet includes the audio data of the first device. Among them, the first broadcast packet is a broadcast packet transmitted through the main broadcast channel, and the second broadcast packet, the third broadcast packet and the fourth broadcast packet are broadcast packets transmitted through the second type of secondary broadcast packets. For example, the first broadcast packet is an ADV_EXT_IND broadcast packet, the second broadcast packet is an AUX_ADV_IND broadcast packet, and the third broadcast packet is an AUX_SYNC_IND broadcast packet.

[0148] The second broadcast channel includes a third broadcast channel, a fourth broadcast channel and a fifth broadcast channel, which may be the same or different; the second time period includes a third time period, a fourth time period and a fifth time period.

[0149] Among them, the second broadcast channel and the second time period satisfy at least one of the following: the third broadcast channel is different from the first broadcast channel; the third time period is different from the first time period; the fourth broadcast channel is different from the first broadcast channel; the fourth time period is different from the first time period; the fifth broadcast channel is different from the first broadcast channel; the fifth time period is different from the first time period.

[0150] Below through Figure 6 The embodiment shown in the figure has the same frequency hopping mode as the above Figure 4 The embodiments shown are described in conjunction with the following embodiments:

[0151] Figure 6 is a flowchart of another method for transmitting audio data according to an exemplary embodiment, which is executed by a first device, see Figure 6 , the method comprises the following steps:

[0152] Step S601: Acquire first broadcast information.

[0153] The first broadcast information includes a fourth broadcast packet, the fourth broadcast packet includes fourth data, the fourth data is used to characterize the sixth broadcast channel used to transmit the fifth broadcast packet and the sixth time period occupied by the sixth broadcast channel, the fifth broadcast packet includes fifth data, the fifth data is used to characterize the seventh broadcast channel used to transmit the sixth broadcast packet and the seventh time period occupied by the seventh broadcast channel, the sixth broadcast packet includes sixth data, the sixth data includes the eighth broadcast channel used to transmit the audio data packet and the eighth time period occupied by the eighth broadcast channel, and the audio data packet includes the audio data of the second device. The first broadcast channel includes the sixth broadcast channel, the seventh broadcast channel and the eighth broadcast channel, and the first time period includes the sixth time period, the seventh time period and the eighth time period.

[0154] For other implementations of step S601, refer to the above steps S401 and S402, which will not be described in detail here.

[0155] Step S602: Acquire initial broadcast information.

[0156] The initial broadcast information includes a first initial broadcast packet, the first initial broadcast packet includes first initial data, the first initial data is used to characterize a first initial broadcast channel for transmitting a second initial broadcast packet and a first initial time period for occupying the first initial broadcast channel, the second initial broadcast packet includes second initial data, the second initial data is used to characterize a second initial broadcast channel for transmitting a third initial broadcast packet and a second initial time period for occupying the second initial broadcast channel, the third initial broadcast packet includes third initial data, the third initial data includes a third initial broadcast channel for transmitting an audio initial data packet and a third initial time period for occupying the third initial broadcast channel, and the audio initial data packet includes audio data of the first device. The initial broadcast channels include the first initial broadcast channel, the second initial broadcast channel and the third initial broadcast channel, and the initial time period includes the first initial time period, the second initial time period and the third initial time period.

[0157] Step S603: Update the first initial data, the second initial data and the third initial data according to the fourth data, the fifth data and the sixth data in the first broadcast information to obtain the first data, the second data and the third data.

[0158] In some embodiments, an unoccupied broadcast channel is determined based on the fourth data, the fifth data, and the sixth data. When at least one broadcast channel among the first initial data, the second initial data, and the third initial data is an unoccupied broadcast channel, the first initial data, the second initial data, and the third initial data are kept unchanged, that is, the first initial data, the second initial data, and the third initial data are used as the first data, the second data, and the third data.

[0159] In some embodiments, an unoccupied time period is determined based on the fourth data, the fifth data, and the sixth data. When at least one time period among the first initial data, the second initial data, and the third initial data is an unoccupied time period, the first initial data, the second initial data, and the third initial data are kept unchanged, that is, the first initial data, the second initial data, and the third initial data are used as the first data, the second data, and the third data.

[0160] In some embodiments, the above two embodiments are combined, that is, when at least one time period among the first initial data, the second initial data and the third initial data is an unoccupied time period, and / or at least one broadcast channel among the first initial data, the second initial data and the third initial data is an unoccupied broadcast channel, the first initial data, the second initial data and the third initial data are kept unchanged.

[0161] In some embodiments, when each broadcast channel in the first initial data, the second initial data, and the third initial data is an occupied broadcast channel, and the time period of occupying each broadcast channel is the occupied time period of each broadcast channel, the first initial data, the second initial data, and the third initial data are updated to obtain the first data, the second data, and the third data.

[0162] In some embodiments, the first initial data is compared with the fourth data, the second initial data is compared with the fifth data, and the third initial data is compared with the sixth data, that is, the sixth broadcast channel is compared with the first initial broadcast channel, and the sixth time period is compared with the first initial time period, the seventh broadcast channel is compared with the second initial broadcast channel, and the seventh time period is compared with the second initial time period, and the eighth broadcast channel is compared with the third initial broadcast channel, and the eighth time period is compared with the third initial time period. Determine a third broadcast channel different from the sixth broadcast channel, and / or a third time period different from the sixth time period, determine a fourth broadcast channel different from the seventh broadcast channel, and / or a fourth time period different from the seventh time period, determine a fifth broadcast channel different from the eighth broadcast channel, and / or a fifth time period different from the eighth time period.

[0163] Optionally, only the initial broadcast channel and the occupied broadcast channel are compared, or only the initial time period and the occupied time period are compared.

[0164] For example, only the initial broadcast channel and the occupied broadcast channel are compared. If multiple first broadcast information is obtained, multiple fourth data are recorded as AuxPtr_ext, multiple fifth data are recorded as SyncInfo_ext, and multiple sixth data are recorded as BIGInfo_ext. The initial broadcast information is obtained, the first initial data is AuxPtr_self, the second initial data is SyncInfo_self, and the third initial data is BigInfo_self, and then AuxPtr_self, SyncInfo_self and BigInfo_sel are updated according to AuxPtr_ext, SyncInfo_ext and BigInfo_ext. That is, according to AuxPtr_ext, an unoccupied broadcast channel is obtained. When the first initial broadcast channel in AuxPtr_self is an unoccupied broadcast channel, AuxPtr_self is kept unchanged, otherwise the first initial broadcast channel is modified to a randomly selected unoccupied broadcast channel. Similarly, obtain an unoccupied broadcast channel according to SyncInfo_ext. When the second initial broadcast channel in SyncInfo_self is an unoccupied broadcast channel, keep SyncInfo_self unchanged; otherwise, modify the second initial broadcast channel to a randomly selected unoccupied broadcast channel; obtain an unoccupied broadcast channel according to BIGInfo_ext. When the third initial broadcast channel in BIGInfo self is an unoccupied broadcast channel, keep BIGInfo self unchanged; otherwise, modify the third initial broadcast channel to a randomly selected unoccupied broadcast channel.

[0165] Step S604: Transmit the audio data of the first device according to the first data, the second data and the third data.

[0166] It should be noted that when the second initial broadcast channel in the second initial broadcast packet is an occupied channel and the fourth broadcast channel is determined, the fourth broadcast channel and the second initial broadcast channel are both added to the modified second broadcast packet, and the fourth broadcast channel corresponds to the second identifier, and the second initial broadcast channel corresponds to the first identifier. For the third device, after obtaining the second broadcast packet, when the third device determines that the second initial broadcast channel corresponding to the first identifier and the fourth broadcast channel corresponding to the second identifier are included in the second broadcast packet, it is determined that the second initial broadcast channel is an occupied channel and data needs to be received on the fourth broadcast channel. Therefore, the third broadcast packet is received on the fourth broadcast channel in the fourth time period.

[0167] Similarly, when the third initial broadcast channel in the third initial broadcast packet is an occupied channel and the fifth broadcast channel is determined, the fifth broadcast channel and the third initial broadcast channel are both added to the modified third broadcast packet, and the fifth broadcast channel corresponds to the second identifier, and the third initial broadcast channel corresponds to the first identifier. For the third device, after obtaining the third broadcast packet, when the third device determines that the third initial broadcast channel corresponding to the first identifier and the fifth broadcast channel corresponding to the second identifier are included in the third broadcast packet, it is determined that the third initial broadcast channel is an occupied channel and data needs to be received on the fifth broadcast channel. Therefore, in the fifth time period, an audio data packet is received on the fifth broadcast channel.

[0168] According to the method provided by the embodiment of the present disclosure, the first device first obtains the first broadcast information, then determines the second broadcast information based on the first broadcast information, and finally transmits the audio data of the first device according to the first data, the second data and the third data. This can avoid the first device and other devices from transmitting audio data on the same channel at the same time, that is, avoid mutual interference between audio data of different devices, thereby reducing the packet loss rate of the audio data and improving the effective transmission rate.
