Abstract
A method of assigning nodes and time slots in a wireless audio node mesh network includes transmitting via a gateway node to nodes in a wireless mesh network, such that nodes in the wireless mesh network that receive transmissions from the gateway node are allocated to a first level as child nodes of the gateway node, transmitting via the first level nodes to further nodes in the wireless mesh network such that further nodes that receive transmissions from the first level nodes are allocated to a second level as child nodes of the first level nodes, and allocating non-conflicting transmission and reception time slots to the gateway node, the first level nodes and the second level nodes.

A method of assigning nodes and time slots in a wireless audio node mesh network, the method comprising:
- transmitting via a gateway node to nodes in a wireless mesh network, such that nodes in the wireless mesh network that receive transmissions from the gateway node are allocated to a first level as child nodes of the gateway node;
- transmitting via the first level nodes to further nodes in the wireless mesh network such that further nodes that receive transmissions from the first level nodes are allocated to a second level as child nodes of the first level nodes;
- and
- allocating non-conflicting transmission and reception time slots to the gateway node, the first level nodes and the second level nodes.
A playback node for an audio mesh network, the playback node comprising:
- a wireless transceiver;
- circuitry coupled to the transceiver, the circuitry configured to cause the transceiver to receive audio packets from parent playback nodes and send audio packets to child playback nodes during assigned time slots;
- a buffer coupled to the circuitry to buffer audio packets for playback;
- and
- a speaker coupled to the circuitry to create sound from the buffered packets.
A method of distributing audio packets to playback nodes of an audio system wireless mesh network, the method comprising:
- receiving audio at a gateway node of the wireless mesh network;
- transmitting audio packets to child nodes in a first level of the wireless mesh network during non-conflicting time slots;
- transmitting received audio packets to further child nodes in further levels of the wireless mesh network in parallel with receiving more audio packets;
- and
- buffering packets for a selected time at a buffer in each node prior to beginning playback of the audio packets.
