Abstract: A system and a method of identifying which networked device of a set of networked devices is mounted at a first mounting location of mounting locations of the set of networked devices known in a management server are disclosed. Each networked device of the set of networked devices has a unique identifier. A predetermined sound is emitted using a loudspeaker of a portable device. Information specifying the first mounting location is further sent from the portable device to the management server. Upon detecting the predetermined sound using a microphone in a first networked device of the set of networked devices, the unique identifier of the first networked device is sent from the first networked device to the management server. At the management server, the unique identifier of the first networked device is then linked to the first mounting location.

Abstract: A method for distributing an audio instruction from a manager site at a client site in a distributed audio system having a plurality of client sites, a generalized audio instruction for playback of audio at the client sites is received via user input at the manager site. The generalized audio instruction includes a plurality of labels which are global in the audio system and are indicative of a time schedule category, an audio zone category, and an audio source category. Pre-defined information which associates the plurality of labels indicative of the time schedule, audio zone, and audio source categories with client site specific identifiers of a time schedule, an audio zone, and an audio source, respectively, is accessed for each of client sites. The generalized audio instruction is adapted using the pre-defined information to generate a specialized audio instruction for each of the one or more client sites.

Abstract: A mobile device includes a communications interface and a processor configured to determine whether an accessory device has been attached via the communications interface. The processor is further configured to configure a high bandwidth link to the accessory device via an initial low power link to the accessory device. The processor is further configured to connect to the accessory device via the high bandwidth link when necessary to perform an operation.
