Method and apparatus for remote control of an audio source such as a wireless microphone system
First Claim
1. A method for remotely controlling a set of functions related to a wireless audio system from a remote central control, said method comprising the steps of:
- providing an audio system that includes a transmitter and a receiver;
detecting an audio signal via an acoustic transducer located within the transmitter;
modulating a tone burst with a frame of data, including a header with address information, a payload and a trailer, said payload of said frame of data containing a plurality of predetermined, real time status values of monitored functions within said transmitter disposed within respective predetermined locations of the frame;
mixing the modulated tone burst with the detected audio signal;
modulating the mixed audio signal and modulated tone burst;
transmitting the modulated audio signal and tone burst from the transmitter to the receiver and storing the frame of data therein;
establishing a link between the receiver of said wireless audio system and a central control for remotely controlling the set of functions through a communication network;
determining whether or not any problems exist by monitoring said data stored in said receiver from said central control;
communicating from said remote control to said audio system appropriate remedial actions to alleviate any of said problems.

Abstract
A method and apparatus is provided for remotely controlling a set of functions for a wireless audio system from a remote control. The method includes the steps of generating a digitally modulated pilot tone, and transmitting this pilot tone within a radio communication to a wireless receiver. The digitally modulated pilot tone carries data about a plurality of functions related to an audio source and its associated transmitter. The method further includes a step of receiving the data at a wireless receiver, augmenting it by information related to the wireless receiver, and communicating the resulting data via a communication network to a remote central control. The method further includes monitoring the resulting data at the remote central control, diagnosing detected problems associated with the wireless audio system, and communicating to the wireless audio system appropriate remedial action to alleviate the detected problems.
