Here, before determining the second timing information of the second broadcast information to be transmitted, whether the first broadcast information exists in the environment may be detected, and by the detection result, whether the first broadcast information exists in the environment can be determined. In practical application, when the first broadcast information exists in the environment, the sending time of each broadcast information needs to be staggered, and when the first broadcast information does not exist in the environment, the phenomenon that the second time sequence information of the second broadcast information conflicts with the time sequence information of other broadcast information does not exist. In the environment, there may be a case where the number of broadcast information to be transmitted is excessive, the amount of data to be processed by staggering the transmission time of each broadcast information being transmitted may increase, in which case the broadcast information to be staggering the transmission time may be further defined, in practical application, the first broadcast information may be broadcast information having a higher degree of urgency, which may be reflected by the urgency of reception of the broadcast information by the intended recipient, in practical application, the degree of urgency corresponding to the broadcast information may be set by the user,

Here, in the case that the detection result indicates that the first broadcast information exists, it is indicated that the second timing information of the second broadcast information needs to be staggered with the first timing information of the first broadcast information, so that the first broadcast information and the second broadcast information are prevented from being sent out at the same time. In practical application, the broadcast information can be transmitted in the form of BIS or BIG based on the bluetooth 5.2 standard, and in the bluetooth 5.2 standard, the first detection result can be determined according to the indication information carried by other first broadcast information in the acquisition environment in the transmission process by the transmitting device, and further, the indication information can also determine the type of the first broadcast information. Fig. 4 is a schematic diagram showing a transmission sequence flow of the first broadcast information and the second broadcast information, and in fig. 4, transmission time of the first broadcast information with high urgency is shifted from transmission time of the second broadcast information with low urgency.
In the above embodiment, whether the first broadcast information exists is detected to obtain a detection result, and when the detection result indicates that the first broadcast information exists, the second time sequence information is determined according to the first time sequence information, so that according to the detection result of whether other broadcast information is sent, the sending time of the broadcast information to be sent and the sending time of the broadcast information being sent can be staggered, and therefore a receiving party can be guaranteed to receive different broadcast information.
In an embodiment, as shown in fig. 5, the detecting whether the first broadcast information exists includes:
s501: and acquiring a first identifier corresponding to the broadcast information in the transmitting state.
Here, the first identifier corresponding to the broadcast information may be used to determine attribute information of the broadcast information, and the different values corresponding to the first identifier represent different attributes of the broadcast information. In practical application, the broadcast information transmitting device may acquire the first identifier corresponding to the broadcast information in the transmission state according to the transmission protocol of the broadcast information.
S502: determining whether the first broadcast information exists in the broadcast information in the transmitting state based on the first identification.
Here, according to the first identification, it may be determined whether first broadcast information exists in broadcast information in a transmission state, wherein the first broadcast information represents broadcast information in a transmission state and having a higher degree of urgency, and then it may be determined whether the first broadcast information exists by determining an identification bit of the degree of urgency of the broadcast information, for example, different numerical identification bits may represent different degrees of urgency, and thus it may be determined whether the first broadcast information is broadcast information having a higher degree of urgency by a correspondence between the numerical value and the degree of urgency.
In the above embodiment, the first identifier corresponding to the broadcast information in the transmission state is obtained, and based on the first identifier, it is determined whether the first broadcast information exists in the broadcast information in the transmission state, and the attribute of the broadcast information is determined by the transmission protocol, so that the broadcast information can be further classified according to the emergency degree, and the transmission time of other broadcast information is staggered from the transmission time of the broadcast information with high emergency degree, so that the broadcast information with high emergency degree is ensured to be successfully received.

In practical applications, the priority of the first broadcast information is high, and the success of the transmission of the first broadcast information should be ensured preferentially, so that other broadcast information needs not to overlap with the transmission time of the first broadcast information.
In the above embodiment, the first identifier characterizes the priority of the broadcast information, and determines the broadcast information with the priority higher than the set priority as the first broadcast information, where the priority of the corresponding first identifier characterizes the priority of the broadcast information, so that the broadcast information with the higher priority can be extracted according to the priority of the broadcast information, thereby being beneficial to determining the transmission time needing to be staggered and being beneficial to successful reception of the broadcast information with the higher priority.

For example, under the bluetooth 5.2 standard, when the value of the first identifier is 0x0800, the broadcast type of the broadcast information is characterized as a game type, which represents the broadcast information for an application in a certain game type, the response time of the broadcast information can be prolonged appropriately, and the corresponding broadcast information has low emergency degree. When the value of the first identifier is 0x0080, the broadcasting type of the broadcasting information is represented as an alarm type, which represents that an emergency situation occurs, the broadcasting information should be responded in a short time, and the corresponding broadcasting information has high emergency degree.
In the above embodiment, the first identifier characterizes the broadcast type of the broadcast information, and the broadcast information of the first identifier as the set broadcast type is determined as the first broadcast information, so that the broadcast information can be distinguished according to the broadcast type, thereby being beneficial to staggering the transmission time of the broadcast information of other broadcast types and the transmission time of the broadcast information of the set broadcast type, improving the transmission efficiency of the broadcast information, and ensuring that different broadcast information can be successfully received.
In an embodiment, the first identifier characterizes a broadcast transmitting device that transmits broadcast information, and when determining whether the first broadcast information exists in the broadcast information in a transmitting state based on the first identifier, the method includes:
and determining the broadcast information of the first broadcast transmitting device identified as the setting as the first broadcast information.
Here, the first identifier may also characterize a broadcasting device that sends out broadcasting information, in practical application, may instruct the same broadcasting sending device to send out one type of broadcasting information, for example, since the broadcasting information carrying alarm information has a high emergency degree, the corresponding broadcasting information is sent out by a specific broadcasting sending, so that whether the sent broadcasting information is the broadcasting information with the high emergency degree can be determined according to the broadcasting sending device, in practical application, the broadcasting sending device that sends out broadcasting information is determined through the first identifier, and when the broadcasting information is sent out by the set broadcasting sending device, the corresponding broadcasting information is determined as the first broadcasting information.
In the above embodiment, when the first identifier characterizes the broadcast transmitting device that transmits the broadcast information, the broadcast information of the broadcast transmitting device that is set by the first identifier is determined as the first broadcast information, and according to the broadcast information that is determined to be high in emergency degree by the broadcast transmitting device, the transmission timing of other broadcast information and the transmission timing of the broadcast information that is high in emergency degree can be staggered, so as to ensure that different broadcast information can be successfully received.
S102: and sending out the second broadcast information according to the second time sequence information.
Here, the second broadcast information is sent according to the second timing information, and in practical application, when there are a plurality of broadcast information sent at the same time, the receiving party can receive one of the plurality of broadcast information, so that the receiving party may miss important information, and the second timing information is not overlapped with the first timing information, so that the sending time of the second broadcast information is staggered from the sending time of other broadcast information, and there is no sending of the plurality of broadcast information at the same time. Thus, the receiving party can be ensured to receive different broadcast information.
In the above embodiment, the second timing information is determined according to the first timing information, where the first timing information characterizes the transmission timing of the first broadcast information in the transmission state, the second timing information characterizes the transmission timing of the second broadcast information in the to-be-transmitted state, the time indicated by the first timing information when the first broadcast information is sent out does not overlap with the time indicated by the second timing information when the second broadcast information is sent out, and the second broadcast information is sent out according to the second timing information.
In an embodiment, as shown in fig. 6, the broadcasting information is characterized as audio data, and the sending the second broadcasting information according to the second timing information includes:
s601: and collecting first audio data corresponding to the first broadcast information.
Here, the second broadcasting information having a low degree of urgency may also receive the first audio data corresponding to the first broadcasting information. In practical application, when detecting the first broadcast information existing in the environment, different first broadcast information can be received at the same time.
S602: and mixing the first audio data into second audio data in the second broadcasting information based on the first time sequence information and the second time sequence information.
Here, mixing the first audio data into the second audio data in the second broadcast information based on the first timing information and the second timing information enables adding the second audio data to the first audio data for an appropriate period of time. In practical application, most of the time in the first audio data is silent, and corresponding warning sounds are emitted when emergency occurs, so that the playing effect of the second audio data in the second broadcast information is not affected when the first audio data is mixed into the second audio data in the second broadcast information.
S603: and sending out the second broadcast information subjected to the sound mixing processing according to the second time sequence information.
Here, the second broadcast information subjected to the audio mixing processing is sent out according to the second time sequence information, so that time sequence conflict with other broadcast information can be avoided, the second broadcast information subjected to the audio mixing processing carries the audio data of the first broadcast information with high emergency degree, the receiver can receive the second broadcast information, meanwhile, the receiver can obtain the audio data of the first broadcast information, the receiving efficiency of the broadcast information is improved, and meanwhile, the success rate of transmitting the first broadcast information with high emergency degree is further improved. As shown in fig. 7, fig. 7 shows a schematic diagram of transmitting the second broadcast information subjected to the mixing processing, transmitting the first broadcast information at time t1 and time t3, transmitting the second broadcast information at time t2, receiving the first audio data of the first broadcast information at time t3, mixing the first audio data into the second audio data in the second broadcast information, and transmitting the second broadcast information subjected to the mixing processing according to the second timing information, that is, at time t 4.
In the above embodiment, the first audio data corresponding to the first broadcast information is collected, based on the first time sequence information and the second time sequence information, the first audio data is mixed into the second audio in the second broadcast information, and the second broadcast information subjected to the mixing processing is sent according to the second time sequence information, so that the content of the broadcast information with high emergency degree can be added into the broadcast information with low emergency degree, and therefore, when the receiver receives the broadcast information with low emergency degree, the content of the broadcast information with high emergency degree can be obtained at the same time, the situation that the receiver cannot timely obtain the content of the broadcast information with high emergency degree is avoided, and meanwhile, the receiving efficiency of the receiver can be improved.
In an embodiment, the broadcast information is characterized as a broadcast synchronization group BIG or a broadcast synchronization stream BIG.
Here, when broadcasting information is transmitted, broadcasting information is transmitted from a single stream to a plurality of receivers using a set of synchronous streams, each stream is a BIS, and a set of BIS is a BIS, and thus broadcasting information is transmitted through the BIS or the BIS, and in practical applications, the bluetooth 5.2 standard is applied when broadcasting information is transmitted. As shown in fig. 8, fig. 8 shows a schematic diagram of a transmission flow of broadcast information.
In the above embodiment, based on the bluetooth protocol, the second broadcast information is sent out according to the second timing, so that the broadcast information can be shared among the plurality of bluetooth devices, and the power consumption of the bluetooth devices for receiving the broadcast information can be reduced.
In an embodiment, the method further comprises:
synchronizing a local clock of a broadcast transmitting apparatus that transmits the second broadcast information with a local clock of a broadcast transmitting apparatus that transmits the first broadcast information.
Here, the broadcast transmitting apparatus is provided with a local clock, so that the broadcast transmitting apparatus can transmit broadcast information according to the corresponding timing information based on the local clock of the broadcast transmitting apparatus. In practical applications, the second timing information should not overlap with the first timing information, and when a clock drift occurs between the local clock of the broadcast transmitting device transmitting the first broadcast information and the local clock of the broadcast transmitting device transmitting the second broadcast information, the transmission time of the first broadcast information overlaps with the transmission time of the second broadcast information. In order to keep the first time sequence information corresponding to the first broadcast information and the second time sequence information corresponding to the second broadcast information in a staggered state, the local clock of the broadcast transmitting device transmitting the second broadcast information is synchronized with the local clock of the broadcast transmitting device transmitting the first broadcast information, and when the local clock of the broadcast transmitting device transmitting the first broadcast information is shifted, the local clock of the broadcast transmitting device transmitting the second broadcast information can be correspondingly adjusted, so that the time sequence is not in conflict all the time.
In the above embodiment, the local clocks of the broadcast transmitting devices that transmit the second broadcast information and the local clocks of the broadcast transmitting devices that transmit the first broadcast information are synchronized, and by synchronizing the local clocks of the different transmitting devices, the situation that the clock drift causes the time sequence conflict of the broadcast information to cause that a plurality of broadcast information are transmitted at the same time can be avoided, which is beneficial to improving the probability of the receiver successfully receiving different broadcast information.
In an embodiment, the synchronizing the local clock of the broadcast transmitting device that transmits the second broadcast information with the local clock of the broadcast transmitting device that transmits the first broadcast information includes:
before determining the second timing information, synchronizing a local clock of a broadcast transmitting apparatus that transmits the second broadcast information with a local clock of a broadcast transmitting apparatus that transmits the first broadcast information.
Here, since the transmission times of the different broadcast information can be staggered by determining the second timing information, in order to ensure the accuracy of the second timing, the local clock of the broadcast transmitting apparatus transmitting the first broadcast information can be synchronized with the local clock of the broadcast transmitting apparatus transmitting the second broadcast information before the second timing information is determined, and thus the local clock of the broadcast transmitting apparatus transmitting the first broadcast information can be identical to the local clock of the broadcast transmitting apparatus transmitting the second broadcast information, and the time indicated by the determined second timing information at which the second broadcast information is transmitted can be kept not to overlap with the time indicated by the first timing information at which the first broadcast information is transmitted.
In the above embodiment, before determining the second timing information, the local clock of the broadcast transmitting device that transmits the second broadcast information is synchronized with the local clock of the broadcast transmitting device that transmits the first broadcast information, so that the transmission times of different broadcast information can be determined based on the same local clock, and thus, non-overlapping of the transmission times of different broadcast information can be ensured.
In an embodiment, the synchronizing the local clock of the broadcast transmitting device that transmits the second broadcast information with the local clock of the broadcast transmitting device that transmits the first broadcast information includes:
in the process of sending the second broadcast information according to the second time sequence information, the local clock of the broadcast sending device sending the second broadcast information is synchronized with the local clock of the broadcast sending device sending the first broadcast information at a set moment.
Here, in order to avoid that the time indicated by the first timing information and the time indicated by the second timing information and used for sending the first broadcast information overlap each other due to clock drift, the local clock of the broadcast sending device sending the second broadcast information and the local clock of the broadcast sending device sending the first broadcast information can be synchronized at a set time in the process of sending the second broadcast information according to the second timing information, so that the occurrence of clock drift can be avoided in the process of sending the second broadcast information, and the sending time of the second broadcast information and the sending time of the first broadcast information are ensured not to overlap.
In the above embodiment, in the process of sending the second broadcast information according to the second timing information, the local clock of the broadcast sending device sending the second broadcast information and the local clock of the broadcast sending device sending the first broadcast information are synchronized at the set time, so that clock drift can be avoided in the sending process, the sending time of different broadcast information can be ensured to be staggered, and successful receiving of different broadcast information is facilitated.
In an embodiment, the method further comprises:
and stopping transmitting the second broadcast information when the number of times of transmitting the second broadcast information is equal to a set threshold value.
Here, a condition for stopping transmission of the broadcast information is set, and when the number of times of transmission of the second broadcast information is equal to a set threshold value, transmission of the second broadcast information is stopped. In practical applications, the broadcast information may have multiple receivers, and when receiving the required broadcast information, different receivers no longer receive the same broadcast information, in which case, if the transmitting device continues to send the same broadcast information, the power consumption of the transmitting device increases, so that the number of times of sending the second broadcast information needs to be limited. In practical application, the threshold value may be set to ensure that most of the receivers can receive the number of times of sending the broadcast information, and in addition, limit the number of times of sending the second broadcast information, and also avoid that the second broadcast information occupies a sending period for a long time, so that the sending time of other broadcast information to be sent is staggered with the sending time of other broadcast information, thereby being beneficial to improving the sending efficiency of the broadcast information and the receiving efficiency of the receiver.
In the above embodiment, when the number of times of transmission of the second broadcast information is equal to the set threshold, the transmission of the second broadcast information is stopped, so that the transmission device can be prevented from continuously transmitting the broadcast information, thereby being beneficial to reducing the power consumption of the transmission device, and improving the efficiency of the transmission device for transmitting the broadcast information.
