Audio data transmission method, device and system, storage medium and earphone

Abstract

The invention discloses an audio data transmission method, device and system, a storage medium and an earphone, and the method comprises the steps: receiving pairing information which comprises an access code and broadcast isochronous group (BIG) information of a source end device, and is derived from one of the source end device and other destination end devices; adding a current synchronous broadcast event to the BIG according to the pairing information, and creating a synchronous broadcast event which is completely aligned with the source end device so as to receive audio data from the source end device or other target end devices; and broadcasting the pairing information in the next synchronous broadcast event. The method can effectively solve the problem that in the prior art, due to environmental interference, distance, blocking and other reasons, audio data transmission cannot be carried out on the target end device, the probability that BIG information is correctly received is improved in a large range, and the advantages of being more reliable and long in distance are brought to audio sharing.

Description

Technical field [0001] The present invention relates to the field of headphones, and more particularly to an audio data transmission method, a device, a system, a storage medium, and a headset. Background technique [0002] The Bluetooth Technology Alliance has released a new generation of Bluetooth audio technology -LAudio, not only in audio quality, but also adds some new practical features for Bluetooth audio, one of the important features of Le Audio, Audio sharing allows the audio source device to broadcast one or more audio streams to an unlimited number of audio receiving devices. [0003] To support audio sharing, Le Audio introduces the Broadcast ISochronousGroup, BIG and Synchronous Broadcast stream (BIADCAST ISOCHRONS, BIS). Such devices have two types: Synchronous Broadcaster and synchronous receiving devices, also known as source devices and destination devices. [0004] The sync broadcast group is created by the source device, including one or more synchronous broad...
