Abstract
An audio distribution system includes an audio source; and a plurality of audio playback devices in communication with each other and with the audio source. A group of the audio playback devices are arranged to render audio content provided by the audio source in synchrony. One of the audio playback devices within the group is configured as an audio master which distributes audio content from the audio source to the other audio playback devices within the group, and one of the plurality of audio playback devices, other than the audio master, is configured as a clock master, which distributes clock information that the group of audio playback devices synchronizes to.
Claims19
An audio distribution system comprising:
- an audio source;
- an access point;
- and
- a plurality of audio playback devices in communication with each other and with the audio source,
- wherein a group of the audio playback devices are arranged to render audio content provided by the audio source in synchrony,
- wherein one of the audio playback devices within the group is configured as an audio master which distributes audio content from the audio source to the other audio playback devices within the group, and wherein one of the plurality of audio playback devices, other than the audio master, is configured as a clock master, which distributes clock information that the group of audio playback devices synchronizes to, and
- wherein the system is configured to select the clock master from among the plurality of audio playback devices based on ping times between the audio playback devices of the plurality of audio playback devices and the access point.
