Abstract:
A wireless multi-channel audio system including an audio source with a wireless transceiver configured to communicate according to a standard wireless protocol and an audio controller, which are collectively configured to establish wireless communications with multiple audio sinks via a corresponding wireless link, to assign each audio sink a corresponding audio channel, to synchronize timing with each audio sink, and to transmit audio information for each audio channel to a corresponding audio sink via a corresponding wireless link. The audio source may inquire as to supported audio parameters, such as sample rate and audio codec, and selects a commonly supported configuration. The audio source may separate audio information into queues for each audio channel for each audio sink. The audio source transmits frames with timestamps and a common start time for synchronization, and the audio sinks use this information to synchronize timing and remain virtually synchronized with each other.
