Communication based on operation mode
Embodiments are provided for utilizing communication routes based operation mode. In an example implementation, while operating in a normal power mode, a playback device maintains information in a network table, the information includes first information associated with a second playback device of the networked media system and second information associated with a third playback device of the networked media system. The playback device determines that the first playback device is to enter a low power mode to draw less power from a battery of the first playback device relative to the normal power mode, and responsive to the determination, foregoing maintaining of the second information in the network table. Thereafter, the playback device determines that the first playback device is to return to normal power mode; and, and in response, synchronizes with the second playback device based at least in part on the first information for playback of audio content.

transitioning from operating in the first mode to operating in a second mode;
while operating in the second mode: (i) foregoing maintaining of the network information in the network table; (ii) receiving, via the second network interface from a mobile device, data representing audio content, and (iii) playing back the audio content via one or more audio transducers and one or more amplifiers;
transitioning from operating in the second mode to operating in the first mode; and
after transitioning back to operating in the first mode, synchronizing, via the first network interface, with a given second playback device based at least in part on the network information for playback of audio content.
9. The method of claim 8 , wherein the second mode is a low-power mode configured to consume less power than the first mode.
10. The method of claim 8 , wherein the first network interface is an 802.11-compatible network interface, and wherein the second network interface is an 802.15-compatible network interface.
