Problems solved by technology

[0004] However, the characteristics of both communication protocols, CIS and BIS, are that the encoded audio data is sent a limited number of times within a fixed communication interval to ensure low delay, synchronization and communication performance of audio transmission. However, in more and more In complex interference and fading environments, especially when there is long-distance transmission with occlusion, it is often difficult to guarantee communication quality or communication reliability with limited multiple transmissions

Abstract

The invention discloses an audio data transmission method, system and device. The method comprises the following steps of when judging that communication quality between any one of a first audio datareceiving device and a second audio data receiving device and sound source equipment does not meet the preset requirement, the other audio data receiving device starts to receive first sound channel audio data and the second sound channel audio data; and enabling the other audio data receiving device to forward the audio data of the corresponding sound channel to one audio data receiving device ofwhich the communication quality does not meet the preset requirement. By utilizing the characteristic that fading at different spatial positions is independent, the reliability of wireless communication is improved through spatial diversity gain, and the communication quality is enhanced.

Description

technical field [0001] The present application belongs to the technical field of wireless communication, and in particular relates to an audio data transmission method, system and device. Background technique [0002] The extensive development of Bluetooth technology has gradually improved Bluetooth products. Stereo audio playback devices such as Bluetooth headsets and Bluetooth speakers centered on smartphones have brought people a better user experience. Especially fully wirelessly connected stereo playback equipment, such as dual wireless stereo bluetooth earphones and dual wireless stereo bluetooth speakers, is especially popular. [0003] At present, in a feasible technology, the left channel audio data receiving device and the right channel audio data receiving device of the dual wireless stereo audio playback device respectively establish a CIS (Connected Isochronous Stream, connection isochronous stream protocol) or BIS with the audio source device (BIS: Broadcast I...
