Abstract

Systems, methods, apparatus, and articles of manufacture to facilitate playback of multimedia content are disclosed. An example apparatus includes a network interface configured to receive audio content over a playback network. A processor comprising instructions which when executed, cause the processor to detect that a portable playback device has joined the playback network. The processor is to update a state variable to indicate that the portable playback device has joined the playback network. The processor is to play audio content received over the playback network based on the state variable. The processor is to detect that the portable playback device is not joined to the playback network. The processor is to, after detecting that the portable playback device is not joined to the playback network, update the state variable to indicate that the portable playback device is not joined to the playback network.

play back the audio content received from the audio source other than the portable playback device; and

after the portable playback device is joined to the network;

receive the audio content from the portable playback device; and

play back the audio content received from the portable playback device.

7. The playback device of claim 1, further comprising program instructions stored on the non-transitory computer-readable storage medium that are executable by the at least one processor to cause the playback device to:

receive audio content from the portable playback device after the portable playback device is connected to the network; and

play back the audio content received from the portable playback device.

8. The playback device of claim 7, further comprising program instructions stored on the non-transitory computer-readable storage medium that are executable by the at least one processor to cause the playback device to:

play back the audio content that was received from the portable playback device after detecting that the portable playback device is no longer connected to the network.

9. The playback device of claim 1, wherein the program instructions that are executable by the at least one processor to cause the playback device to determine that the portable playback has joined the zone group comprise program instructions that are executable by the at least one processor to cause to playback device to receive a request from the portable playback device to join the zone group with the playback device.

10. The playback device of claim 1, further comprising program instructions stored on the non-transitory computer-readable storage medium that are executable by the at least one processor to cause the playback device to:

after the state variable has been updated to indicate that the portable playback device is connected to the network, transmit, to the portable playback device, a household identifier that identifies the network.

11. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium is provisioned with program instructions that are executable to cause a playback device to:
