Systems and methods for synchronizing wirless audio base stations

摘要

Systems and methods for adaptive OTA (over-the-air) synchronization of RF (radio frequency) base stations are described herein. Using these systems and methods, base stations in wireless audio systems can automatically identify externally sourced base station clocks and merge overlapping clock system domains, thereby eliminating the need for complex base station management and network configuration.

1. A method for extending an existing clock synchronization domain having a first primary base station and one or more secondary base stations wirelessly coupled to the first primary base station and being configured to derive a clock signal from a clock generated by the first primary base station, comprising:
periodically scanning, by a second primary base station, for a predetermined period of time for a unique identifier in a broadcast message transmitted by either the first primary base station or any of the one or more secondary base stations comprising the existing clock synchronization domain; detecting, by the second primary base station, the unique identifier in the broadcast message periodically transmitted by either the first primary base station or any of the one or more secondary base stations comprising the existing clock synchronization domain; determining that the unique identifier detected in the broadcast message is different than a unique identifier assigned to the second primary base station; and the second primary base station transitioning to be a new secondary base station in the existing clock synchronization domain, and synchronizing an internally generated clock signal with a signal in a broadcast message transmitted by either the first primary base station or any of the one or more secondary base stations.
