Fig. 1 is a flow chart of a conventional BIG broadcast access. Taking the main bluetooth receiving device and the auxiliary bluetooth receiving device as a pair of bluetooth headphones as an example, a plurality of BIG bit broadcast audio sources (such as broadcast source 1 and broadcast source 2 in fig. 1) may exist in the surrounding environment, when the BIG bit broadcast audio sources need to be accessed, the same bluetooth headphones may be accessed to the audio source 1 one by one, the other is accessed to the audio source 2, the same audio source cannot be ensured to be accessed, even if the same audio source is accessed, due to different access time, the situation that one headphone is accessed to the sound first, the condition that one headphone is accessed to the sound later, and the access and playing experience of the BIG bit broadcast audio are poor may occur.
In view of this, the present application provides a BIG broadcast access method, apparatus, device, system and storage medium, one of a pair of bluetooth receiving devices is used as a primary bluetooth receiving device, the other is used as a secondary bluetooth device, the primary bluetooth selects and determines a BIG broadcast audio source, and then related information is sent to the secondary bluetooth device to access, so that the problem that a pair of bluetooth receiving devices access to different BIG broadcast audio sources is avoided, and meanwhile, the primary bluetooth receiving device and the secondary bluetooth device agree on a playing time, and when reaching the playing starting time, the primary bluetooth receiving device and the secondary bluetooth device are connected to the BIG broadcast audio source together and synchronously play the audio stream, so that the problem that the audio stream is not played synchronously is avoided, and the playing experience of BIG broadcast audio is effectively improved.

The technical solution of the present application is specifically described below in conjunction with the system shown in fig. 2.
Referring to fig. 4, fig. 4 is a flow chart of a BIG broadcast access method according to an embodiment of the present application, and the method may be applied to the bluetooth system shown in fig. 2. The method comprises the following steps:
s401, the main Bluetooth receiving device determines a target BIG broadcasting audio source.
The convention herein is that: the primary bluetooth receiving device referred to in the present application refers to a device that can actively establish an LE-BIS communication link with a bluetooth transmitting device, such as a primary earpiece of a pair of bluetooth earpieces, which may be TWS (True Wireless Stereo ) earpieces. The secondary bluetooth receiving device referred to in the present application refers to a device that needs the primary bluetooth receiving device to forward the communication link information to access the LE-BIS communication link, such as a secondary headset of a pair of bluetooth headsets. The primary bluetooth receiving device may correspond to one secondary bluetooth receiving device, or may correspond to a plurality of secondary bluetooth receiving devices, which is not limited in this application.
In one embodiment, the primary bluetooth receiving device and the secondary bluetooth receiving device pre-establish a connection between the primary and secondary, and then establish a communication connection between the primary and secondary, where the communication connection may be a BLE communication connection, a classical communication bluetooth connection, or the like.
It should be further noted that, a plurality of BIG broadcast audio sources may exist in the surrounding environment of the master bluetooth receiving device, each BIG broadcast audio source may correspond to a bluetooth transmitting device, and the master bluetooth receiving device selects one of the plurality of BIG broadcast audio sources as the target BIG broadcast audio source.
In one embodiment, the master bluetooth receiving device determines a target BIG broadcast audio source, comprising: when the access broadcast operation of a user is detected or an access broadcast request of the auxiliary Bluetooth receiving device is received, acquiring a broadcast source information set in a preset communication range; and determining a target broadcast source from the broadcast source information set.
As a possible implementation, the preset communication range may be a maximum communication range that the master bluetooth receiving device can cover.
For example, when detecting an access broadcast operation of a user, or when receiving an access broadcast request of a secondary bluetooth receiving device, the primary bluetooth receiving device may start a scanning mode, start a BLE scan to scan BIG broadcast sources within a preset communication range, and the searched BIG broadcast sources are broadcast source information sets, where the primary bluetooth receiving device determines one of the BIG broadcast sources as a target BIG broadcast source.
In one embodiment, the determining a target broadcast source from the set of broadcast source information includes: and determining the broadcast source with the strongest signal strength in the broadcast source information set as a target broadcast source, or determining the broadcast source with the earliest discovery time in the broadcast source information set as a target broadcast source, or determining the broadcast source selected by the user in the broadcast source information set as a target broadcast source.
S402, the main Bluetooth receiving equipment accesses the periodic broadcast of the target BIG broadcast audio source, and determines the starting playing time according to the BIG synchronous information of the periodic broadcast.
As a possible implementation, the BIG synchronization information may be the BIG info information.
In one embodiment, the master bluetooth receiving device accesses a periodic broadcast of the target BIG broadcast audio source, and determines a start playing time according to BIG synchronization information of the periodic broadcast, including: accessing to the periodic broadcast of the target BIG broadcast audio source to acquire BIG synchronous information in the periodic broadcast; and determining the playing starting time according to the packet counting parameter in the BIG synchronous information.
For example, after determining the target BIG broadcast audio source, the master bluetooth receiving device may access to the periodic broadcast of the target BIG broadcast audio source, and obtain BIG fo information of the target BIG broadcast source from the periodic broadcast, where the master bluetooth receiving device may first determine the starting playing time of the current broadcast audio according to the BIG fo information without accessing the BIS data stream for playing.
Specifically, referring to fig. 5, a schematic format diagram of a Biginfo information provided in this embodiment of the present application is shown, where the master bluetooth receiving device may determine a start playing time according to a packet count (bisPayloadCount) parameter in the Biginfo information, for example, the start playing time is set to a time corresponding to a data packet of a bispayloadcount+n sequence, and a physical meaning of the start playing time may be to agree to receive and play a BIS audio stream from an nth data packet after a current packet count begins. Wherein N can be calculated from the estimated time T and BIS interval (BIS interval) and satisfies the following formula:
N＝T/bis interva
s403, the main Bluetooth receiving device sends the BIG synchronous information and the starting playing time to the auxiliary Bluetooth receiving device.
As a possible implementation manner, the primary bluetooth receiving device may package the BIG synchronization information and the start playing time and then send the BIG synchronization information and the start playing time to the secondary bluetooth receiving device, or may send the BIG synchronization information and the start playing time to the secondary bluetooth receiving device respectively.
In an embodiment, the primary bluetooth receiving device sends the BIG synchronization information and the start playing time to the secondary bluetooth receiving device, which may be sending the BIG synchronization information and the start playing time to the secondary bluetooth receiving device through a BLE communication connection or a classical bluetooth communication connection.
S404, the auxiliary Bluetooth receiving device receives BIG synchronous information sent by the main Bluetooth receiving device and starts playing time.
S405, the secondary Bluetooth receiving equipment accesses the periodic broadcast of the target BIG broadcast audio source according to the BIG synchronous information.
As a possible implementation manner, after the secondary bluetooth receiving device receives the BIG synchronization information and starts the playing time, the secondary bluetooth receiving device may start broadcast scanning, and select a BIG target broadcast source corresponding to the BIG synchronization information to start to access. Similarly, the secondary bluetooth receiving device may synchronize to the periodic broadcast of the BIG target broadcast source, and then start playing only when the secondary bluetooth receiving device reaches the start playing time without accessing the BIG data stream for playing.
In one embodiment, the user may initiate the operation of accessing the broadcast at the primary bluetooth device, or may initiate the operation of accessing the broadcast at the secondary bluetooth receiving device. When an operation of accessing a broadcast is initiated on the secondary bluetooth receiving device, the secondary bluetooth receiving device may transmit an access broadcast request to the primary bluetooth receiving device, so that the primary bluetooth receiving device determines a target BIG broadcast audio source according to the access broadcast request.
As a possible implementation, the access broadcast request may be sent by the secondary bluetooth receiving device to the primary bluetooth receiving device via a BLE communication connection or a classical bluetooth communication connection or the like.
S406, the auxiliary Bluetooth receiving device and the main Bluetooth receiving device synchronously play the audio data at the starting playing time.
For example, the secondary bluetooth receiving device may compare the bisPayloadCounter in the Biginfo information with the start playing time, if the start playing time is not reached, keep the state of broadcasting in the current access period but not accessing the BIS data stream, and if the start playing time is reached, access the BIS data stream and keep playing the audio data synchronously with the primary bluetooth receiving device.
For another example, please refer to fig. 6, which is a schematic diagram of a situation of BIG broadcast access according to an embodiment of the present application. Taking a main Bluetooth receiving device as a main earphone and an auxiliary Bluetooth receiving device as an auxiliary earphone as an example, firstly establishing connection between the two earphones, setting one earphone as the main earphone, and sending an access broadcast request to the main earphone when a user operates the auxiliary earphone to want to access a target BIG broadcast source. The master earphone may first scan nearby broadcast audio sources to determine a target BIG broadcast source access. Periodic broadcasts of the target BIG broadcast source are first accessed, but the BIS data stream is not accessed. The master earphone acquires the bigingfo, determines a starting playing time according to the bisPayloadcounter in the bigingfo, and then sends the starting playing time to the slave earphone together with the relevant information of the target BIG broadcast source. After receiving the related information, the slave earphone scans and accesses the corresponding target BIG broadcast source according to the related information, and does not access the BIS audio stream after receiving the periodic broadcast. The master earphone and the slave earphone are connected to start playing after the set playing starting time.
In one embodiment, the method further comprises: if the starting playing time does not meet the current playing condition, the auxiliary Bluetooth receiving device sends a request for modifying the playing time to the main Bluetooth receiving device; the main Bluetooth receiving device receives a request for modifying playing time of the auxiliary Bluetooth receiving device; the master Bluetooth receiving device modifies the starting playing time according to the playing time modification request; the main Bluetooth receiving equipment sends the modified starting playing time to the auxiliary Bluetooth receiving equipment, and updates the starting playing time with the modified starting playing time; the auxiliary Bluetooth receiving device receives the modified starting playing time of the main Bluetooth receiving device, and updates the starting playing time according to the modified starting playing time.
As a possible implementation manner, if the start-up playing time exceeds the current time, the current playing condition may not be considered to be satisfied, or if the start-up playing time does not exceed the current time, but the time of the secondary bluetooth receiving device for predicting the successful access period broadcast may exceed the start-up playing time, the current playing condition may also be considered to be not satisfied.
For example, when the start-up playing time does not meet the current playing condition, the auxiliary bluetooth receiving device may initiate a request for modifying the playing time to the main bluetooth receiving device, and after receiving the request for modifying the playing time, the main bluetooth receiving device recalculates the start-up playing time, and sends the modified start-up playing time to the auxiliary bluetooth receiving device, and at the same time, updates its own start-up playing time with the modified start-up playing time. For example, as shown in fig. 7, a situation diagram of BIG broadcast access provided in the embodiment of the present application may request the primary bluetooth receiving device to reset the start-up playing time if the secondary bluetooth receiving device does not successfully access to the periodic broadcast and misses the start-up playing time.
Therefore, the target BIG broadcast audio source can be determined through the main Bluetooth receiving device, the target BIG broadcast audio source is accessed to the periodic broadcast of the target BIG broadcast audio source, the starting playing time is determined according to the BIG synchronous information of the periodic broadcast, then the BIG synchronous information and the starting playing time are sent to the auxiliary Bluetooth receiving device, and the auxiliary Bluetooth receiving device is firstly accessed to the periodic broadcast based on the BIG synchronous information and is not accessed to the target BIG broadcast audio source.
