Network device for media playback

Tangible, non-transitory computer-readable media comprising program instructions, wherein the program instructions, when executed by one or more processors, cause a first network device to perform functions comprising:

• receiving, via a first network interface from a third network device, one or more messages that cause the first network device to obtain media content and operate as part of a group with at least a second network device, wherein the first network interface is configured for communication via a first communication protocol;
• obtaining media content and operating as part of the group with at least the second network device based on the one or more messages;
• while operating as part of the group with at least the second network device and obtaining the media content, (i) transmitting, via a second network interface, audio associated with the obtained media content to the second network device, wherein the second network interface is configured for communication via a second communication protocol, and (ii) causing video associated with the obtained media content to be output while the second network device outputs audio associated with the obtained media content;
• receiving, via the second network interface, a first command to adjust a volume setting from a network device different than the first network device, the second network device, and the third network device;
• based on the first command to adjust the volume setting, transmitting a first volume adjustment command to the second network device;
• receiving, via the first network interface, a second command to adjust the volume setting from the third network device;
• and
• based on the second command to adjust the volume setting, transmitting a second volume adjustment command to the second network device.

A system comprising a first network device and a second network device, wherein the first network device comprises:

• a first network interface configured for communication via a first communication protocol;
• a second network interface configured for communication via a second communication protocol;
• at least one first processor;
• at least one first tangible, non-transitory computer-readable medium;
• and
• first program instructions stored on the at least one first tangible, non-transitory computer-readable medium that are executable by the at least one first processor such that the first network device is configured to:
• receive, via the first network interface from a third network device, one or more messages that cause the first network device to obtain media content and operate as part of a group with at least a second network device;
• obtain media content and operate as part of the group with at least the second network device based on the one or more messages;
• while operating as part of the group with at least the second network device and obtaining the media content, (i) transmit, via the second network interface, audio associated with the obtained media content to the second network device, and (ii) cause video associated with the obtained media content to be output while the second network device outputs audio associated with the obtained media content;
• receive, via the second network interface, a first command to adjust a volume setting from a network device different than the first network device, the second network device, and the third network device;
• based on the first command to adjust the volume setting, transmit a first volume adjustment command to the second network device;
• receive, via the first network interface, a second command to adjust the volume setting from the third network device;
• and
• based on the second command to adjust the volume setting, transmit a second volume adjustment command to the second network device.

A set of one or more processors configured for implementation within a first network device, wherein the set of one or more processors comprises tangible, non-transitory computer-readable media comprising program instructions that are executable by the set of one or more processors such that the first network device is configured to:

• receive, via a first network interface from a third network device, one or more messages that cause the first network device to obtain media content and operate as part of a group with at least a second network device, wherein the first network interface is configured for communication via a first communication protocol;
• obtain media content and operate as part of the group with at least the second network device based on the one or more messages;
• while operating as part of the group with at least the second network device and obtaining the media content, (i) transmit, via a second network interface, audio associated with the obtained media content to the second network device, wherein the second network interface is configured for communication via a second communication protocol, and (ii) cause video associated with the obtained media content to be output while the second network device outputs audio associated with the obtained media content;
• receive, via the second network interface, a first command to adjust a volume setting from a network device different than the first network device, the second network device, and the third network device;
• based on the first command to adjust the volume setting, transmit a first volume adjustment command to the second network device;
• receive, via the first network interface, a second command to adjust the volume setting from the third network device;
• and
• based on the second command to adjust the volume setting, transmit a second volume adjustment command to the second network device.
