The application discloses a
Bluetooth earphone dynamic teaming method and
system based on Auracast protocol, and belongs to the technical field of
wireless communication and audio
processing. The method comprises the following steps: embedding a scene semantic
label in a broadcast assistant
signal by a
broadcasting device; collecting self context information by a listening device, calculating a matching weight with each broadcast source through a recommendation decision engine, and realizing intelligent sorting, filtering or automatic joining of a broadcast group. The
broadcasting device supports creating a dynamic hierarchical broadcast group with role permissions, time-
limited access codes and multiple audio sub-streams. In the overlapping coverage area, the listening device triggers intelligent switching based on
signal quality and context matching degree, and realizes seamless connection by using pre-synchronization technology. In addition, the
system synchronizes group state information through an auxiliary channel to realize state
visualization and interaction. The application upgrades Auracast broadcast from "manual, static and equal" to "automatic, dynamic and intelligent", greatly improving the convenience, management accuracy and immersion experience in the multi-user audio sharing scene.
