WIRELESS COORDINATION OF AUDIO SOURCES

Abstract

An audio/video (A / V) hub that coordinates playback of audio content is described. In particular, the A / V hub may calculate current time offsets between clocks in electronic devices and a clock in the A / V hub based on differences between transmit times of frames from the electronic devices and receive times when the frames were received. For example, the current time offsets may be calculated using wireless ranging by ignoring distances between the A / Vhub and the electronic devices. Then, the A / Vhub may transmit, to the electronic devices, one or more frames that include audio content and playback timing information, which may specify playback times when the electronic devices are to playback the audio content based on the current time offsets. Furthermore, the playback times of the electronic devices may have a temporal relationship so that the playback of the audio content by the electronic devices is coordinated.
