Abstract

Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. Particularly, the embodiments described herein enable two or more playback devices to be paired, such that multi-channel audio is achieved. Such embodiments may be used to produce stereo and multi-channel audio environments for television and movies.

19. The first playback device of claim 1, further comprising a set of instructions that, when executed by the processor, cause the first playback device to carry out functions including:

after detecting the command, identifying the second playback device.

8. A method comprising:

receiving, at first playback device from a source device, multi-channel audio data comprising a plurality of audio channels;

detecting, by the first playback device, a command to form a multi-channel pair in which the first playback device is designated to play at least a first audio channel of the multi-channel audio data and a second playback device is designated to play at least a second audio channel of the multi-channel audio data, wherein the first audio channel is different from the second audio channel; and

after detecting the command, (i) sending, from the first playback device to the second playback device, at least the second audio channel of the multi-channel audio data, and (ii) playing, by the first playback device, the first audio channel of the multi-channel audio data.

9. The method of claim 8, wherein the command comprises a manual command.

10. The method of claim 9, wherein the manual command comprises a command input via one or more buttons on the first playback device.

11. The method of claim 8, wherein detecting the command to form the multi-channel pair comprises one of (i) detecting a command to form a stereo pair in which the first playback device is designated as a left speaker and the second playback device is designated as a right speaker or (ii) detecting a command to form a stereo pair in which the first playback device is designated as a right speaker and the second playback device is designated as a left speaker.
