Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
The technical scheme of the application is suitable for a Bluetooth communication scene, in particular to a scene using BIG communication in the Bluetooth communication scene. When BIG communication is used, such as when a user needs to switch to listen to a new synchronized broadcast group audio (i.e., BIG audio) nearby, the user needs to re-operate on the bluetooth receiving device to access the new synchronized broadcast group audio source. In a possible technical solution, as shown in fig. 1, an application scenario of a user switching a synchronous broadcast group audio source may be that a synchronous broadcast group audio source 1 and a synchronous broadcast group audio source 2 exist in a current environment area, and a current bluetooth receiving device receives and plays audio data of the synchronous broadcast group audio source 1, if the user wants to switch to the synchronous broadcast group audio source 2, the user needs to use a bluetooth assistant device (such as a mobile phone, a computer, etc.) to control the bluetooth receiving device to access the synchronous broadcast group audio source 2 by scanning a two-dimensional code or searching the mobile phone, etc.
As can be seen from fig. 1, if the synchronous broadcast group audio needs to be switched, the user needs to scan or search through the bluetooth assistant device, and then the bluetooth assistant device controls the bluetooth receiving device to receive the audio data of the new synchronous broadcast group audio, which is very complicated in flow, and the user needs to manually switch, so that the switching convenience of the bluetooth broadcast audio is poor.
In view of this, the application provides a bluetooth broadcast audio switching scheme, which can realize automatic switching of bluetooth broadcast audio and improve the switching convenience of bluetooth broadcast audio. The technical scheme of the application is specifically described below.
Referring to fig. 2, fig. 2 is a flow chart of a bluetooth broadcast audio switching method according to an embodiment of the present application. As shown in fig. 2, the method can be applied to a bluetooth receiving device, which can be a mobile phone, a bluetooth headset, a computer, etc. and can support synchronous broadcast group communication, and can receive and play audio data. The method shown in fig. 2 comprises the steps of:
s201, scanning audio information of the synchronous broadcast group audio within a preset range.
It should be noted that the preset range may refer to a maximum bluetooth scanning range that the bluetooth receiving device can cover.
In one embodiment, the audio information of the synchronous broadcast group audio includes at least: and the notice information, the broadcast identification and the signal strength of the synchronous broadcast group audio are provided.
In a possible implementation manner, the announcement information of the synchronous broadcast group audio may include information such as a size, a format, a transmission rate, an error handling manner, and the like of an audio data packet. The announcement information ensures that communication and data transmission between the sender and the receiver can be performed efficiently and that audio data can be decoded and processed correctly as intended.
In one possible implementation, the broadcast identification of the synchronized broadcast group audio may be used to distinguish between different synchronized broadcast group audio. The bluetooth receiving device may correspond the signal strength to the broadcast identification for identifying signal strengths of different synchronized broadcast group audio.
In one possible implementation, the signal strength of the synchronized broadcast group audio may be used to evaluate the quality of the signal and the reliability of the communication. In general, the signal strength may be related to the distance that the device has been transmitting before the synchronized broadcast group audio source, the greater the signal strength, which generally means that the distance between the devices is closer, which may indicate that the synchronized broadcast group audio has a more stable connection and better audio transmission performance, while the weaker signal strength may indicate that the distance between the devices is farther or blocked, which may be weaker.
In one embodiment, the scanning the audio information of the synchronous broadcast group audio within the preset range includes: and scanning the audio information of the synchronous broadcast group audio within a preset range according to a preset scanning period.
As a possible implementation, the preset scan period may include a scan interval and a scan window, where the scan interval refers to a time interval between two scans by the bluetooth receiving device, and the scan window refers to a time window in which the device listens for the synchronous broadcast channel in each scan. The preset scanning period may be a default interval period of the bluetooth receiving device, or an interval period set by a user according to needs.
For example, the bluetooth receiving device may automatically turn on a scan mode according to a preset scan period, in which the bluetooth receiving device may monitor a synchronous broadcast channel, and if audio information of synchronous broadcast audio is detected within a scan window, the bluetooth receiving device will receive and decode the audio information. After completing the reception and processing of the audio data of the synchronous broadcast audio within the current scanning window, the bluetooth receiving device may wait for the next scanning interval and then repeat the above scanning process.
In one embodiment, the scanning the audio information of the synchronous broadcast group audio within the preset range includes: and scanning the audio information of the synchronous broadcast group audio within a preset range by using the residual synchronous interval bandwidth, wherein the residual synchronous interval bandwidth is the bandwidth left after the currently played synchronous broadcast group audio is received.
It should be noted that the synchronization Interval (ISO) bandwidth is a dedicated bandwidth for real-time audio transmission.
As a possible implementation, the remaining idle ISO bandwidth and the ISO bandwidth that has completed receiving the audio data can be used as the audio information for scanning the synchronized broadcast group audio, except for the window used to receive the audio data of the synchronized broadcast group audio that is currently being played in every two ISO events. This way, maximization of ISO bandwidth allocation efficiency can be achieved.
For example, as shown in fig. 3, a schematic diagram of audio information of synchronous broadcast group audio using ISO residual bandwidth scanning is provided in the present application. As shown in fig. 3, the audio information of the synchronized broadcast group audio is received successfully in both the first ISO transmission period P0 data and the pre-transmitted P1 data, and the remaining ISO bandwidth of the first ISO transmission period may be used for bluetooth scanning (in some embodiments, bluetooth low energy BLE mode). In addition, since the first ISO transmission period has successfully received both P0 data and P1 data, the ISO bandwidth originally used to receive P0 data and P1 data in the second ISO transmission period may also be used for bluetooth scanning (e.g., the first BLE SCAN region in fig. 3). The second ISO transmission period is to receive the data of pre-transmission P2, but the reception is not successful in fig. 3, so the transmission window of the third ISO transmission period P2 can continue to receive the data of P3.
S202, if the audio information of the synchronous broadcast group audio meets a preset switching condition, determining the synchronous broadcast group audio as a target synchronous broadcast group audio.
As a possible implementation, the synchronized broadcast group audio may be determined to be the target synchronized broadcast group audio if: firstly, the signal intensity of the scanned synchronous broadcasting group audio is larger than that of the currently played synchronous broadcasting group audio, and secondly, the receiving success rate of the currently played synchronous broadcasting group audio is smaller than a preset success rate.
The preset success rate can be defaulted by the Bluetooth receiving device or can be customized by a user according to the needs.
As a possible implementation manner, the reception success rate may be determined according to a data packet loss rate of the synchronized broadcast group audio. For example, the bluetooth receiving device may determine the number of synchronous broadcast group data packets transmitted by the synchronous broadcast group audio transmitting end according to the audio information of the synchronous broadcast group audio, and determine the number of lost synchronous broadcast group data packets compared with the number of received synchronous broadcast group data packets, and then may determine the packet loss rate according to the following formula:
packet loss rate= (packet loss count/transmitted packet count) ×100%
Further, the bluetooth receiving device may determine the reception success rate according to the following formula:
reception success rate= (1-packet loss rate) ×100%
In one embodiment, if the audio information of the synchronized broadcast group audio meets a preset switching condition, determining the synchronized broadcast group audio as the target synchronized broadcast group audio includes: and if the signal intensity of the synchronous broadcasting group audio is greater than the signal intensity of the synchronous broadcasting group audio played currently and the receiving success rate of the synchronous broadcasting group audio played currently is less than the preset success rate, determining the synchronous broadcasting group audio as the target synchronous broadcasting group audio.
In one embodiment, if the signal strength of the synchronized broadcast group audio is greater than the signal strength of the currently played synchronized broadcast group audio and the reception success rate of the currently played synchronized broadcast group audio is less than a preset success rate, determining that the synchronized broadcast group audio is the target synchronized broadcast group audio includes: if the signal intensity of the plurality of synchronous broadcast group audios is larger than the signal intensity of the synchronous broadcast group audio currently played, and the receiving success rate of the synchronous broadcast group audio currently played is smaller than the preset success rate, selecting the synchronous broadcast group audio with the largest signal intensity from the plurality of synchronous broadcast group audios as the target synchronous broadcast audio.
For example, if the bluetooth receiving device scans that the signal strength of the new synchronized broadcast group audio is greater than the signal strength of the currently played synchronized broadcast group audio and the reception success rate of the signal strength of the currently played synchronized broadcast group audio is less than the preset success rate of the bluetooth receiving device, the bluetooth receiving device may determine that the new synchronized broadcast group audio is the target synchronized broadcast audio and execute the step S203. At this time, if the bluetooth receiving apparatus scans that a plurality of new synchronized broadcast group audios all satisfy the above condition, the synchronized broadcast group audio having the strongest signal strength may be selected therefrom as the target synchronized broadcast audio, and the step S203 is performed.
S203, switching the currently played synchronous broadcast group audio to the target synchronous broadcast group audio for playing.
As a possible implementation, the bluetooth receiving device may end the currently playing synchronized broadcast group audio first, and then perform the handover process.
In one embodiment, the switching the currently playing synchronized broadcast group audio to the target synchronized broadcast group audio for playing includes: ending the currently played synchronous broadcasting group audio and acquiring synchronous broadcasting group information; and receiving and playing the target synchronous broadcast group audio according to the synchronous broadcast group information.
It should be noted that, the content of the synchronized broadcast group information (Biginfo) includes, but is not limited to, a frequency point used by each synchronized broadcast group, how many synchronized broadcast streams each synchronized broadcast group includes, a size of a synchronization interval bandwidth, a number of retransmissions of data included in each synchronized broadcast stream, a size definition of a data packet, and encryption information.
For example, the bluetooth receiving device may end the currently played synchronized broadcast group audio first, then access the synchronized broadcast group to obtain the synchronized broadcast group information, and receive the target synchronized broadcast group audio according to the synchronized broadcast group information to play the audio.
As a possible implementation manner, please refer to fig. 4, which is a timing diagram of a synchronized broadcast event (Big event) provided by an embodiment of the present application, two parameters, big-offset and offset Unit, prescribe at what time point (time period) the bluetooth receiving device receiving the synchronized broadcast group information should be ready to start receiving audio data in the synchronized broadcast stream. When the Bluetooth receiving device successfully receives the synchronous broadcast group information once and the audio data in the first synchronous broadcast stream, the Bluetooth receiving device marks that the Bluetooth receiving device is accessed into a synchronous broadcast group of a certain audio source, and the audio source device can send the synchronous broadcast group information through a periodical synchronous broadcast event while broadcasting the audio data, so that the Bluetooth receiving device informs the starting point position of the next synchronous broadcast event according to the synchronous broadcast group information, grasps the rule of the synchronous broadcast event of the audio source device, and receives the audio data. By the above way, any Bluetooth receiving device correctly receiving the synchronous broadcast group information can join the synchronous broadcast group according to the information in the Bluetooth receiving device, receive synchronous broadcast group audio in a synchronous broadcast event and play synchronously.
In the technical scheme corresponding to fig. 2, the bluetooth receiving device scans the audio information of the synchronous broadcast group audio within the preset range, if the audio information of the synchronous broadcast group audio meets the preset switching condition, the synchronous broadcast group audio can be determined to be the target synchronous broadcast group audio, and the currently played synchronous broadcast group audio is switched to be the target synchronous broadcast group audio for playing, so that the step that a user scans a two-dimensional code by using the bluetooth assistant device or manually starts searching and switches is omitted, the bluetooth receiving device can automatically switch the synchronous broadcast group audio when the preset switching condition is met, and the convenience of switching the bluetooth broadcast audio is improved.
