Abstract

Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.

First claim

We claim:

1. A first playback device comprising:
a processor; and
memory having stored thereon instructions executable by the processor to cause the first playback device to perform functions comprising:
receiving audio information;
determining whether the received audio information is low latency audio;
based on the determination that the received audio information is low latency audio, (i) selecting a first frequency channel of a first spectrum; (ii) transmitting to the…
