Techniques for Enabling Interoperability between Media Playback Systems

A method implemented by a playback device, the method comprising:

• operating as a group coordinator for a synchrony group comprising a first set of one or more playback devices and a second set of one or more playback devices;
• receiving media content for playback by the synchrony group;
• transmitting the media content to the first set of one or more playback devices via a first wireless network interface of the playback device over a first wireless data network, wherein the first wireless network interface is configured to operate in accordance with an IEEE 802.15 standard;
• transmitting the media content to the second set of one or more playback devices via a second wireless network interface of the playback device over a second wireless data network different from the first wireless data network, wherein the second wireless network interface is configured to operate in accordance with an IEEE 802.11 standard;
• and
• causing the synchrony group to play back the media content in synchrony.

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium is provisioned with program instructions that, when executed by at least one processor, cause a playback device to:

• operate as a group coordinator for a synchrony group comprising a first set of one or more playback devices and a second set of one or more playback devices;
• receive media content for playback by the synchrony group;
• transmit the media content to the first set of one or more playback devices via a first wireless network interface of the playback device over a first wireless data network, wherein the first wireless network interface is configured to operate in accordance with an IEEE 802.15 standard;
• transmit the media content to the second set of one or more playback devices via a second wireless network interface of the playback device over a second wireless data network different from the first wireless data network, wherein the second wireless network interface is configured to operate in accordance with an IEEE 802.11 standard;
• and
• cause the synchrony group to play back the media content in synchrony.
