Embodiment 1

[0090] figure 2 A flow chart of an audio data communication method according to Embodiment 1 of the present application is shown.

[0091] Such as figure 2 As shown, the audio data communication method according to Embodiment 1 of the present application includes:

[0092] S201. The first device receives and demodulates audio data from the audio source device.

[0093] During specific implementation, S201 may be implemented by using common methods in the prior art, which will not be described in detail here in this application.

[0094] In this embodiment, the first device is a master device, and the second device is a slave device.

[0095] S202. Decode the audio data.

[0096] During specific implementation, S202 may be implemented by adopting common methods in the prior art, which will not be described in detail here in this application.

[0097] S203, re-encode the decoded audio data of one channel according to the predetermined encoding frame length, and then send ...

Embodiment 2

[0110] Figure 5 A flow chart of the audio data communication method according to Embodiment 2 of the present application is shown.

[0111] In this method, part of the content is consistent with the audio data communication method in Embodiment 1 of the present application, so its implementation can refer to the implementation of the corresponding content in Embodiment 1 of the present application, and the repetition will not be repeated.

[0112] Such as Figure 5 As shown, the audio data communication method according to Embodiment 2 of the present application includes:

[0113] S501. The first device receives and demodulates audio data from the audio source device through a first wireless communication link.

[0114] S502. Decode the audio data.

[0115] S503, re-encode the decoded audio data of one channel according to the encoding frame length, and send it through the second wireless communication link on the first time slot at a predetermined communication interval; ...

Embodiment 3

[0139] Figure 6 A flow chart of the audio data communication method according to Embodiment 3 of the present application is shown in .

[0140] It should be understood that the second device in Embodiment 3 of the present application is used as the receiving end in communication, that is, the aforementioned slave device. Therefore, the communication time slots and communication intervals used by it are the same as or corresponding to the communication time slots and communication intervals adopted by the first device in Embodiment 1; that is, the sending time slots of the first device in Embodiment 1 correspond to For the receiving time slot of the second device in the embodiment of the present application, therefore, the implementation of the communication time slot and the communication interval can refer to the relevant description in the first embodiment of the present application, and repeated descriptions will not be repeated.

[0141] Such as Figure 6 As shown, the ...

Abstract

The embodiment of the invention provides a wireless communication system and equipment, and the method comprises the steps that a first device receives audio data from a sound source device through afirst wireless communication link, forwards at least one part of the audio data to a second device through a second wireless communication link, and provides link information of the first device and asound source device to the second device; the second device evaluates the channel quality between the second device and a sound source device based on the link information of the first device and thesound source device; the first device evaluates the channel quality between the first device and a sound source device; and the first device determines whether to exchange a master-slave role with the second device based on the channel quality between the second device and the sound source device and the channel quality between the first device and the sound source device. The master-slave role can be effectively adjusted, and the stable performance in the communication process is ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a wireless communication system and equipment. Background technique [0002] The extensive development of Bluetooth technology has made Bluetooth products and services a part of people's lives, especially audio applications such as Bluetooth headsets and Bluetooth speakers centered on smartphones have brought great convenience to people's lives. Fully wirelessly connected dual wireless stereo playback devices, such as dual wireless stereo bluetooth earphones and dual wireless stereo bluetooth speakers, are even more popular. [0003] The left and right channel playback devices in the dual wireless stereo playback devices usually use Bluetooth asynchronous link (ACL: Asynchronous Connection-Oriented Link) to send audio data between the master device and the audio source device, and between the master and slave devices, that is, , the master device receives aud...
