US Patent 10154122 Grouping in a system with multiple media playback protocols

A network media system forms a group comprising a first networked device and a second networked device using a first media playback protocol. The network media system includes the first networked device and the second networked device. The network media system determines a group coordinator for the group using the first media playback protocol. The network media system transmits, to a media source device, a group network identity using a second media playback protocol. The media source device and one of the first networked device and the second networked device are configured to use the first media playback protocol and the second media playback protocol. The first media playback protocol and the second media playback protocol are incompatible.
